    Have you seen a yellow-and-black salamander (火蜥蜴)? How about a scarlet frog? Scientists haven’t spotted either species in more than 20 years. What happened to them? Are the creatures still out there, or are they extinct?
    Those are questions that scientists hope to answer. They recently set out around the world in search of those and other long-missing amphibians. An amphibian is an animal that spends part of its life in water and part on land. Frog, toads(蟾蜍), and salamanders are amphibians.
    The experts are looking for about 100 species. They are searching at least 14 countries on five continents. They will look for the salamander in North America. They hope to find the scarlet frog in South America. They’re also looking for species in Africa, Asia and Australia.
    Scientists are hopeful that they’ll find the amphibians—and soon! If the creatures are out there, they may need help. Many amphibians are endangered. The animals face many dangers including pollution and diseases. People cut down the forests where they live.
    “If researchers can find the missing creatures, they might be able to figure out how to save them,” explains expert Robin Moore. He began searching for the amphibians earlier this month.
    “This search will tell us a lot about how amphibians are doing,” Moore told WR News. “I don’t know what we will find, but that makes the search even more exciting.”
    Lost in the Wild
    Scientists’ hunt for missing amphibians is under way. Read about some of the species they hope to find.
    Turkestanian salamander
    This salamander is a mystery to scientists. Experts found a few of them more than 100 years ago, but none have been seen ever since.
    Gastric brooding frog
    Experts first discovered this frog in 1914 in eastern Australia. It may be extinct because of disease and habitat loss.
    Rio Pescado stubfoot toad
    Last sighting: 1995, in South America
    Scientists hope to find this spotted toad in rivers and rainforests in Ecuador. The animal faces threats including pollution and disease.
    小题1: Which of the following animals hasn’t been seen for over a century?
    A．Rio Pescado stubfoot toad.
    B．Gastric brooding frog.
    C．Turkestanian salamander.
    D．Scarlet frog.
    小题2:It can be learned from the passage that _____.
    A．the scarlet frog used to live in Africa
    B．researchers have no way to save amphibians
    C．the scientists will search 14 countries at most
    D．Robin Moore has begun his search for amphibians
    小题3: Why do the scientists want to find the missing amphibians?
    A．Because they want to rescue the missing amphibians.
    B．Because they want to set up a scientific program.
    C．Because they want to do a scientific research on the missing amphibians.
    D．Because they want to publish a report about the missing amphibians on WR News.
    小题4: What does Moore think of the search for endangered amphibians?
    A．It’s hopeful.B．It’s interesting.
    C．It’s tiring.D．It’s dangerous.

    小题1:C
    小题2:D
    小题3:A
    小题4:B

    小题1:C 细节理解题。由文中的Turkestanian salamander Last sighting: 1909, in Asia可知答案。
    小题2: D 细节理解题。由第五段中的He began searching for the amphibians earlier this month.可知，Robin Moore已经开始寻找濒危两栖动物了。
    小题3:A 细节理解题。由第五段第一句话可知，科学家们发起这项寻找濒临灭绝的两栖动物的活动的目的是拯救它们。故答案为A。
    小题4: B 推理判断题。由第六段“This search will tell us a lot about how amphibians are doing,” Moore told WR News. “I don’t know what we will find, but that makes the search even more exciting.”可知，Moore认为这个寻找过程会很有趣。

    An alcohol breath test (ABT) is often used by the police to find out whether a person is drunk while driving.In the United States，the legal blood alcohol limit is 0.08% for people aged 21 years or older，while people under 21 are not allowed to drive a car with any level of alcohol in their body.A “positive” test result，a result over the legal limit，allows the police to arrest the driver.However，many people who tested positive on the test have claimed that they only drank a “non­alcoholic” energy drink.Can one of these energy drinks really cause someone to test positive on an ABT？Researchers in Missouri set up an experiment to find out.
    First，the amount of alcohol in 27 different popular energy drinks was measured.All but one had an alcohol level greater than 0.005%.In nine of the 27 drinks，the alcohol level was at least 0.096%.The scientists then investigated the possibility that these small levels of alcohol could be discovered by an ABT.They asked test subjects to drink a full can or bottle of an energy drink and then gave each subject an ABT one minute and 15 minutes after the drink was finished.
    For 11 of the 27 energy drinks，the ABT did find the presence of alcohol if the test was given within one minute after the drink was taken.However，alcohol could not be discovered for any of the drinks if the test was given 15 minutes after the drink was consumed.This shows that when the test is taken plays an important role in the test result.The sooner the test is conducted after the consumption of these drinks，the more likely a positive alcohol reading will be obtained.
    小题1:What is the legal alcohol level for a 20­year­old driver in the US?
    A．0.000%.　B．0.005%.
    C．0.080%.　D．0.096%.
    小题2:What is the purpose of the Missouri experiment?
    A．To introduce a new method of calculating blood alcohol levels.
    B．To discover the relation between energy drinks and ABT test results.
    C．To warn people of the dangers of drinking energy drinks.
    D．To change the current legal alcohol limit for drivers in the United States.
    小题3:The underlined word “subjects” in Paragraph 2 refers to________.
    A．the things that are being discussed
    B．areas of knowledge studied in school
    C．the participants in an experiment
    D．the people who belong to a country
    小题4:Which of the following affects the ABT test result most for energy drink consumers?
    A．The age of the person who takes the test.
    B．The place where the test is given.
    C．The equipment that the test uses.
    D．The time when the test is taken.
    小题5:Which of the following is true according to the passage?
    A．A driver whose blood alcohol level is found to be 0.1% will be arrested.
    B．No energy drinks really cause anyone to test positive on an ABT.
    C．Few popular energy drinks contain alcohol in them.
    D．Those taking an ABT 15 minutes after drinking alcohol cannot be found out.

    Research has shown that two-thirds of human conversation is taken up not with discussion of the cultural or political problems of the day, not heated debates about films we've just watched or books we've just finished reading, but plain and simple ____.
    Language is our greatest treasure as a species, and what do we ____ do with it? We gossip. About others' behaviour and private lives, such as who's doing what with whom, who's in and who's out-and why; how to deal with difficult ____ situations involving children, lovers, and colleagues.
    So why are we keen on gossiping? Are we just natural ____, of both time and words? Or do we talk a lot about nothing in particular simply to avoid facing up to the really important issues of life? It's not the case according to Professor Robin Dunbar. In fact, in his latest book, Grooming, Gossip and the Evolution of Language, the psychologist says gossip is one of these really____issues.
    Dunbar ____ the traditional view that language was developed by the men at the early stage of social development in order to organize their manly hunting activities more effectively, or even to promote the exchange of poetic stories about their origins and the supernatural. Instead he suggests that language evolved among women. We don't spend two-thirds of our time gossiping just because we can talk, argues Dunbar—____, he goes on to say, language evolved specifically to allow us to gossip.
    Dunbar arrived at his cheery theory by studying the ____ of the higher primates（灵长类动物）like monkeys. By means of grooming--cleaning the fur by brushing it, monkeys form groups with other individuals on whom they can rely for support in the event of some kind of conflict within the group or____ from outside it.
    As we human beings evolve from a particular branch of the primate family, Dunbar ____ that at one time in our history we did much the same. Grouping together made sense because the bigger the group, the greater the ____ it provided; on the other hand, the bigger the group, the greater the stresses of living close to others. Grooming helped to ____ the pressure and calm everybody down.
    But as the groups got bigger and bigger, the amount of time spent in grooming activities also had to be ____ to maintain its effectiveness. Clearly, a more ____ kind of grooming was needed, and thus language evolved as a kind of vocal（有声的）grooming which allowed humans to develop relationship with ever-larger groups by exchanging information over a wider network of individuals than would be possible by one-to-one ____ contact.
    小题1:
    A．claimB．descriptionC．gossipD．language

    Password (密码) strength has been a topic about the Internet lately. I have seen lots of clever methods for generating and remembering strong passwords. Some are better than others, but in my opinion, none are adequate. Here's the problem: It doesn't matter how strong your passwords are if you use the same one on multiple sites. All it takes is for a site to get hacked(侵入), like Gawker media, or even Sony did, and now your super­strong password has been stolen, and every site on which you used that password has been accessed.
    So, the bottom line is that no matter how strong your passwords are, and no matter what clever tricks you use to help you remember them, if you surf internet often, the only truly secure password system is what you need.
    Enter LastPass. It's not the only password manager out there, but I like it the best. You create ONE strong password that you have to memorize and use it to access your LastPass database. The LastPass database is stored online, on LastPass's servers. LastPass recognizes the site you're on and automatically logs you in (after, optionally, asking you to re­enter your master password). LastPass also has automatic form fill and automatic password generation. This means that you can have a different, unique, very strong password for every site you log into, but you only have to remember one master password. It's the best of both worlds.
    One argument against LastPass is that if their database is attacked, then all of your sites are in danger, and that's true, but given that their entire line of work is keeping that information safe, I'm willing to take that chance. The alternative is rolling dice(掷骰子) or picking phrases to create passwords, writing all of them down on a piece of paper or something, and then having to manually type them in when I go to a site. A terrible mess.
    There is a free version of LastPass, with some additional features unlocked if you pay a $12 a year subscription.
    ­Joshua Bardwell 
    小题1:The writer thinks using the same password everywhere is ________.
    A．dangerousB．convenient
    C．appropriateD．adequate
    小题2:When using Lastpass, users have to remember ________.
    A．all passwords used
    B．the last password
    C．unique password each time
    D．the master password only
    小题3:Critics are against Lastpass because ________.
    A．they have better ways to create password
    B．they think rolling dice is more convenient
    C．they have no faith in Lastpass database's safety
    D．Gawker media and Lastpass were hacked once

    A．share his experience
    B．introduce a product of good quality
    C．advertise his product

    Pupils remember more and behave better when 3D images areused in lessons，research suggests.They are quicker to learn andabsorb new concepts，and display higher levels of concentration.
    Professor Anne Bamford，of the University of the Arts，London，studied the effectiveness of 3D content in 15 schools across seven countries，including the UK.Pupils in 3D classes can remember more than those in the 2D classes after four weeks，improving test scores by an average of 1 7 percent compared with eight percent for 2D lessons.They gave more detailed answer to the tasks and were more likely to think in 3D, using hand gestures and mime(模仿动作) to answer the test questions successfully.
    The teachers commented that the pupils in the 3D groups had deeper understanding，increased attention span, more motivation and higher engagement in the lessons.
    Children are used to 3D with the rise of computer games that use the technology­90 percent of those in the study had seen a 3D film.Schools would need 3D­enabled projectors(投影仪)，laptops with good picture capabilities,3D software and glasses for children to introduce animations(动作) into classrooms.
    But Danny Nicholson，an educationist，said the technology would be impractical to use inschools and could be costly.He said，“While I think the idea of 3D technology is very interesting，I worry that 3D is a bit of an expensive gimmick(小玩意儿)．There are a few cases where a true3D image might help，but most of the time，good 2D models that can be moved would be just aseffective.”
    In the US，one school district in Colorado is already in the process of having 1,000 3Dprojectors fixed in classrooms.And the University of Caledonia, which carries out scientific research into the Lake Tabon Basin, has used 3D presentations with Grade Six pupils.Those who watched the 3D presentations were more engrossed and reported a general increase in their interest in science compared with students who watched the 2D version.
    小题1:What is the main idea of the first three paragraphs?
    A．There are slight differences between 3D and 2D images.
    B．Pupils perform better when 3D images are used in classes.
    C．Schools have difficulties in making full use of 3D technology.
    D．3D technology is always more effective than 2D technology.
    小题2:Danny Nicholson holds the view that 3D ________.
    A．is of no help in classes
    B．has a bright future in classes
    C．is more practical than 2D models
    D．may not be affordable for schools
    小题3:What can we learn from the last paragraph?
    A．3D technology will replace 2D models in the future.
    B．Many pupils are now more Interested In science than before.
    C．Teachers will use the 3D technology through specific training.
    D．3D will soon be put into use in one school district in Colorado.
    小题4:The underlined word “engrossed” in the last paragraph means ________.
    A．absorbedB．annoyed

    　　Bananas are one of the world’s most important food crops. They are also one of the most valuable exports. Bananas do not grow from seeds. Instead, they grow from existing plants. Bananas are threatened by disease because all the plants on a farm are copies of each other. They all share the same genetic weaknesses. For example, the Cavendish banana is most popular in North American and European markets. However, some kinds of fungus organisms easily infect the Cavendish. Black Sigatoka disease affects the leaves of Cavendish banana plants. The disease is controlled on large farms by putting chemicals on the plants’ leaves. Farmers put anti-fungal chemicals on their crops up to once a week.

    Another fungal disease is more serious. Panama disease attacks the roots of the banana plants. There is no chemical treatment for this disease. Infected plants must be destroyed. Panama disease has affected crops in Southeast Asia, Australia and South Africa. There is concern that it may spread to bananas grown in the Americas. This could threaten an important export product for Central and South America.
    The International Network for the Improvement of Banana and Plantain supports research on bananas. The group has headquarters in France and other offices in the major banana-growing areas of the world. The group says that more research must be done to develop improved kinds of bananas. The group says that fungal diseases mainly affect only one kind of banana. In fact, there are five hundred different kinds of bananas. Food and Agriculture Organization of the United Nations has said that the Cavendish banana represents only 10% of world production.
    The U. N. agency says farmers should grow different kinds of bananas. This protects against diseases that affect only one kind. Experts warn that disease may cause the Cavendish banana to disappear. This happened earlier to another popular banana because of its genetic weakness against disease.
    小题1:What does this passage mainly tell us?
    A．Bananas are the world’s most important food crops.
    B．The risk to a popular banana shows need to grow other kinds.
    C．There are five hundred different kinds of bananas.
    D．How to grow bananas in different countries.
    小题2:Bananas are threatened by disease because　　　.
    A．they grow from seeds
    B．they are one of the most valuable exports
    C．the only way to prevent it is to put chemicals on their leaves
    D．they have genetic weaknesses against disease
    小题3: Panama disease　　　.
    A．doesn’t belong to fungal disease
    B．affects the leaves of banana plants
    C．destroys bananas more seriously than Black Sigatoka disease
    D．has spread to bananas all over the world
    小题4: We can infer from Paragraph 3 that　　　.
    A．the center of the group is in the US
    B．the Cavendish banana covers only a small part of the yield of bananas
    C．the key to solving the disease is to research all kinds of bananas
    D．each fungal disease affects five hundred different kinds of bananas

    Technology and the present generation of kids go hand in hand. Taking advantage of this factor, Lim Hojoon, the designer from South Korea, has come up with an educational gadget (小装置) especially for children. 
    Kidget, as the name suggests, is a combination of two words – kid and gadget. This kid-friendly gadget has various uses. When your child is in a mood to read, it takes the form of a storybook. When the mood is to draw and color this wonder gadget turns into a perfect canvas (画布). Your child can freely give color to all his/her imaginations. Should he or she wish to have some fun, see this device change into a musical instrument. You too would enjoy doing activities with your loved one using this gadget. This touch screen device will definitely prove to be an ideal friend.
    As many parents agree, in this age of technological advancements it is much easier to introduce children to new gadgets than adults. While many adults refrain (克制) from trying out something new, kids are more than prepared to take the leap. Keeping this fact in mind, Kidget is the perfect gift for the child of the 21st century. You will be surprised to see how fast your little one gets acquainted with the device. You might even find yourself lagging (落后) behind at times.
    Kidget has another hidden advantage. It helps take the load off young shoulders. With three things rolled into one, a child has much less books, stationary items and related goods to carry. It comes with a promise to make life simpler for kids. Not only is it simple to use but also easy to carry along. The stylish protective case comes with a belt attached to it. Children up to 14 years of age, the targeted audience, enjoy the freedom that comes with it.
    小题1:The Kidget probably can’t serve as a ______.
    A．storybook B．perfect canvas
    C．musical instrumentD．television

    Kids undergo a large amount of pressure and stress during their school exams, which can often become quite overwhelming (to much) for them. It may be the first experience of stress, at this level, they have ever experienced and therefore quite frightening. Yes, you may say that it's all a part of growing up and therefore good lessons for them to learn, and to an extent I agree with you. However, it’s important to learn how to prepare for life’s challenges so that they aren’t overwhelming or scary and so that we are able to manage them the best we can.
    Here are some tips you can use during your kids exam time.
    Break their revision plan down into small parts. Doing this will help transform what once seemed like a huge impossible task into a more manageable one.
    Help them arrange properly so that the subjects they like the least (perhaps ones that require more time and effort) are worked on first; once they are out of the way, it will help reduce the worry.
    Plan week on week to make sure they are on track. Ticking items of a list each week will help them to feel good about themselves and their progress.
    Create rewards for all the ticks - a favourite TV programme, a delicious snack, an hour’s surfing the Internet, computer games or whatever it was that they enjoy the most. This will encourage them to carry on and make them feel good.
    Think of strategies on how to deal with exams calmly so their anxieties don't get the better of them.
    Talk about times in their lives when they had been successful at something and look at the qualities they used to get them there - determination, persistence, hard work, patience, positivity, dedication - discuss how they can apply these skills to their exams.
    Acknowledge that if they do their best that is good enough.
    Ensure they realize that this period in their lives will pass and that exams are only a temporary time in their lives; nothing can and does last forever.
    Ensure they keep their eye on the prize: enjoying their long summer holiday when the exams are finished; giving them something to look forward to will help to motivate them and provide a positive end in sight.
    小题1:According to paragraph 1, it’s important to learn how to prepare for exams because___.
    A．it is a part of growing up.
    B．It is the first experience of stress
    C．it helps kid release stress and do better.
    D．it is important to get a good mark in exams.
    小题2:Which subjects should be worked on first?
    A．Their best ones.B．Their favourite ones.
    C．the easiest onesD．the most difficult ones
    小题3:According to the passage, which of the following is true?
    A．Kid should become aware of the importance of exams.
    B．Kids should learn to deal with exam pressure independently.
    C．Parents should keep their kids away from entertainment.
    D．Parents should care about the psychological development of children.

    Most parents of kids under age 8 don't worry about how much time they spend watching TV or using other media, from computers to smart phones to tablets PCs, according to a new survey that found a child's use of media often reflects how much time parents spend in the similar way．
    ¨We generally found that media use is not a source of conflict in the home" for families with young children, Ellen Wartella, a researcher from Northwestem University, told USA Today． She led a survey of 2,326 parents who have children 8 and younger．It found that in 80 percent of families, children's media use was not a problem, with 55 percent “not too" or“ not at all"  concerned about it． It also showed parents have more positive than negative feelings about how media consumption affects a child's learning and the development of creativity．The exception is video games, which are viewed more negatively than TV, computers or mobile devices．“Parents rated video games as more likely to have a negative effect on children's school performance, attention time, creativity, social skills, behavior and sleep than any other medium," the researchers said in a news conference about the survey．
    ¨The findings exposes a generational shift （转移） in parental attitudes about technology's role in young children's lives," said Wartella．“Today's parents grew up with technology as a central pact of their lives, so they think about it differently than earlier generations of parents, instead of a battle with kids on one side and parents on the other, the use of media and technology has become a family affair． "
    The researchers identified three media environments created by parents: media-centric （39 percent of families） , media-moderate （45%）and media-light （16%）． Children  in media-centric families spend at least three hours more each day watching TV or using computers, video games and tablet PCs don't make parenting easier．And 88 percent of parents say they are most likely to turn to toys or activities to keep their children occupied．Slightly fewer turn to books （79%） and TV（78%）．
    The survey didn't look at how media affects children． That's a topic that the American Academy of Pediatrics has handled a number of times． The AAP says studies have found too much media use can lead to attention- problems, school difficulties, sleep and eating disorders and being fat． In addition, the Internet and cell phones can provide platforms for illegal and risky behaviors．¨By limiting screen time and offering educational media and non-electronic formats （格式）such as books, newspapers and board games, and watching television with their children, parents can help guide their children's media experience． Putting questionable content into context and teaching kids a700ut advertising contributes to their media literacy （素养） ," it says．
    The pediatricians' group says parents should have “screen-free zones"  and TV should be turned off during dinner． At most, it recommends children and teens engage with entertainment media for no more than two hours a day and that should be high-quality content． It is important for kids to spend time on outdoor play, reading, hobbies  and  using their imaginations  in free  play．“ Kids  under 2 should not use television and other entertainment media because their brains are developing quickly and they learn best from direct human interaction," the group says．
    An article on screen time by t．he Mayo Clinic also notes problems linked t．o over screen time, including  being  fat, irregular  sleep , behavioral  problems , weak  school  performance , violence  and  less time for active and creative play．
    小题1:Parents have more negative than positive feelings about media consumption like    ．
    A．computersB．smart phones
    C．video gamesD．tablets PCs
    小题2:Most parents don't worry about kid's media use because        ．
    A．they can limit the screen time
    B．they want their children happy
    C．they also grew up with technology
    D．they can teach their children themselves
    小题3:From the data of the survey, we learn       ．
    A．children in media-centric families are smarter than others
    B．children in media-light families spend one hour watching TV
    C．more than half of the parents think children's media use was a problem
    D．media-centric children spend more than three hours each day on media use
    小题4:To make parenting easier, most parents probably        ．
    A．try to persuade their children to read books
    B．ask their children questions while watching TV
    C．allow their children watching TV or using computers
    D．turn to toys or activities to keep their children occupied
    小题5:Which of the following is a suggestion by the researchers?
    A．Media use time for babies under 2 should be limited．
    B．Entertainment media use should be high-quality content．
    C．Schools should provide more time for active and creative play．
    D．Home media use should provide platforms for illegal and risky behaviors．
