Hello! My name is Lisa, and I am a lioness. I live on the open grasslands of Africa with my family. Lions living in a group are called a pride.
My father is strong and powerful. He and his cousin are the leaders of our pride. The other members are my mother, her sisters, and their children.
The area where a pride lives is big! We roar (咆哮) to tell each other where we are and to warn strangers to stay away.
Come to meet my new baby brother. His name is Leon. See the spots on his fur? We lions are born spotted or striped (有条纹的). As we grow older, the spots gradually disappear.
Lionesses usually spend their entire lives with their birth pride, but Leon will leave when he is about three years old. He’ll run around with a male (雄性的) friend or relative for a few years until they take over a pride of their own.
But for now, we have lots of fun together. We often play and fight for hours, which can help us practice skills that we will need for hunting.
We lions keep ourselves very clean. Just like a house cat, I clean my fur with my tongue. We clean for each other, too, to show we’re friends.
Lions like to sleep for most of the day. We hunt in the cool evening. Female (雌性的) lions hunt more often than male lions. We work together as a team. At the right moment, we attack and kill our prey. Then we share it. Male lions usually eat first. Females eat next. Baby lions are the last to eat. The smallest one gets the least food.
Since we are full, it’s time to go to find a nice place for a sleep. Bye!
【小题1】From the text, we can learn that Lisa comes from______.
| A．Asia | B．Africa | C．Europe | D．America |
| A．the animal that is hunted |
| B．the animal that is dangerous |
| C．the animal that is powerful |
| D．the animal that is ill |

Nuclear power's danger to health, safety, and even life itself can be summed up in one word: radiation.
Nuclear radiation has a certain mystery about it, partly because it cannot be detected by human senses. It can't be seen or heard, or touched or tasted, even though it may be all around us. There are other things like that. For example, radio waves are all around us but we can't detect them, sense them, without a radio receiver. Similarly, we can't sense radioactivity without a radiation detector. But unlike common radio waves, nuclear radiation is not harmless to human beings and other living things.
At very high levels, radiation can kill an animal or human being immediately by killing masses of cells in vital organs. But even the lowest levels can do serious damage. There is no levels of radiation that is completely safe. If the radiation does not hit anything important, the damage may not be serious. This is the case when only a few cells are hit, and if they are killed immediately. Your body will replace the dead cells with healthy ones. But if the few cells are only damaged, and if they reproduce themselves, you may be in trouble. They can grow into cancer. Sometimes this does not show up for many years.
This is another reason for some of the mystery about nuclear radiation. Serious damage can be done without the victim being aware at the time that damage has occurred. A person can be irradiated(辐射)and feel fine, then die for cancer five, ten, or twenty years later as a result. Or a child can be born weak as a result of radiation absorbed by its grandparents.
Radiation can hurt us. We must know the truth.
【小题1】Which of the following statements is true?
| A．Nuclear radiation is just like common radio waves. |
| B．Nuclear radiation can cause cancer to human beings. |
| C．Nuclear radiation can be detected by human senses. |
| D．Nuclear radiation can be safe to human beings if its level is low. |
| A．By damaging its heart. |
| B．By killing a few cells. |
| C．By hitting any place in its body. |
| D．By killing many cells in important organs. |
| A．die of cancer after many years |
| B．die immediately |
| C．have a child who may be born weak |
| D．all of the above |

A blind baby is doubly handicapped. Not only is it unable to see, but because it cannot receive the visual stimulus（刺激）from its environment that a sighted child does, it is likely to be slow in intellectual development. Now the ten-month old son of Dr. and Mrs. Dennis Daughters is the subject of an unusual psychological experiment designed to prevent a lag（滞后）in the learning process. With the aid of a sonar-type electronic that he wears on his head, infant(婴儿) Dennis is learning to identify the people and objects in the world around him by means of echoes(回声).
The device is an improvement of the “Sonicguide”, an instrument produced by Telesensory Systems, Inc., of Palo Alto, Calif, and used by blind adults in addition to a smart or guide dog. As adapted for Dennis, it consists of a battery-powered system about the size of a half dollar that is on a headgear. A transmitter sends out an ultrasonic(超声的) pulse that creates an 80 degree cone of sound at 6 feet. Echoes from objects within the cone are perceived (felt) as sounds that vary in pitch(音调) and volume(音量) with the size and distance of the object.
The closer an object is, the lower the pitch, and the larger the object, the louder the signal. Hard surfaces produce a sharp ping, while soft ones send back signals with a slightly fuzzy quality. An object slightly to the right of Denny’s sends back a louder sound to his right ear than to the left. Thus , by simply moving his head right and left and up and down, he can not only locate an object but also get some notion of its shape and size, thanks to the varying qualities of sounds reaching his ears as the cone of ultrasound(超声波) passes its edges. Dennis likes to use the device to play a kind of peek-a-boo with his mother. Standing on her knee and facing her directly, he receives a strong signal in both ears. By turning his head away, he makes her seem to disappear. “From the first time he wore it,” says Mrs. Daughters, “it was like a light going on in his head.”
What remains to be determined is how well the device will help Dennis cope with his surroundings as he begins to walk and venture further into his environment.
Meanwhile, Telesensory, Inc, is working on the development of sonar(声纳) device with somewhat the same sensitivity as Dennis’s for use by school-age children.
【小题1】Dr. and Mrs. Daughters’ research is directed to ________.
| A．helping the blind to see and learn as well as others |
| B．benefiting the learning process of blind children |
| C．solving blind children’s psychological problems |
| D．finding out how children develop intellectually |
| A．he already lags behind the sighted children |
| B．he leads a life as normal as any other children |
| C．he is at the early stage of the learning process |
| D．he has the aid of a sonar-type electronic device |
| A．Its first design was designed for blind adults. |
| B．Its battery is as small as a half-dollar coin. |
| C．It is functionally similar to a sane and guide dog. |
| D．It has been improved by Telesensory Systems, Inc. |
| A．the edge of an object |
| B．the edge of the device |
| C．the boundary of Dennis’ movement |
| D．the boundary of the sound pitch. |

If English means endless new words, difficult grammar and sometimes strange pronunciation, you are wrong. Haven’t you noticed that you have become smarter since you started to learn a language?
According to a new study by a British university, learning a second language can lead to an increase in your brain power. Researchers found that learning other languages changes grey matter. This is the area of the brain which processes information. It is similar to the way that exercise builds muscles.?
The study also found the younger people learn a second language, the greater the effect is.
A team led by Dr Andrea Mechelli, from University College London, took a group of Britons who only spoke English. They were compared with a group of “early bilinguals” who had learnt a second language before the age of five, as well as a number of later learners.
Scans showed that grey matter density(密度)in the brain was greater in bilinguals than in people without a second language. But the longer a person waited before mastering a new language, the smaller the difference.?
“Our findings suggest that the structure of the brain is changed by the experience of learning a second language,” said the scientists.?
It means that the change itself increases the ability to learn.?
Professor Dylan Vaughan Jones of the University of Wales, has researched the link between bilingualism and maths skills. “Having two languages gives you two windows on the world and makes the brain more flexible(灵活的),”he said. “You are actually going beyond language and have a better understanding of different ideas.”
The findings were matched in a study of native Italian speakers who had learned English as a second language between the ages of two and 34. Reading, writing, and comprehension were all tested. The results showed that the younger they started to learn, the better. “Studying a language means you get an entrance to another world,” explained the scientists.
【小题1】The main subject talked about in this passage is ______.
| A．science on learning a second language |

| A．make people believe language learning helps grey matter work well |
| B．prove that one needs more practice when he (she) is learning a language |
| C．to show the importance of using the language when you learn the language |
| D．say language is also a kind of physical labor |
| A．a researcher on language learning |
| B．an English native speaker |
| C．an active language learner |
| D．a person who can speak two languages |
| A．the ability of learning a second language is changing all the time |

Cold weather can be hard on pets, just like it can be hard on people. Sometimes owners forget that their cats are just as used to the warm shelter as they are. Some owners will leave their animals outside for a long period of time, thinking that all animals are used to living outdoors. This can put their pet in danger of serious illness. There are things you can do to keep your animal warm and safe.
Keep your pets inside as much as you can when the weather is bad. If you have to take them out, stay outside with them. When you’re cold enough to go inside, they probably are too. If you must leave them outside for a long time, make sure they have a warm, solid shelter against the wind, thick bedding, and plenty of non-frozen water.
If left alone outside, dogs and cats can be very smart in their search for warm shelter. They can dig into snow banks or hide somewhere. Watch them closely when they are left outdoors, and provide them with shelter of good quality. Keep an eye on your pet’s water. Sometimes owners don’t realize that a water bowl has frozen and their pet can’t get anything to drink. Animals that don’t have clean and unfrozen water may drink dirty water outside, which may contain something unhealthy for them.
【小题1】The word shelter in paragraph one means:
| A．warm clothes | B．a hiding place | C．proper temperature | D．diet food |
| A．They are often forgotten by their owners. |
| B．They like to stay in warm places. |
| C．They build their own shelters. |
| D．They are used to living outdoors. |
| A．To keep company. |
| B．To keep them from eating bad food |
| C．To help them find shelters. |
| D．To know when to bring them inside |
| A．run short of clean water | B．dig deep holes for fun |
| C．dirty the snow nearby | D．get lost in the wild |
| A．To solve a problem |
| B．To give practical advice |
| C．To tell an interesting story |
| D．To present a research result. |

Dreams can be familiar and strange, fantastical or boring, but some dreams might be connected to the mental processes that help us learn. In a recent study, scientists found a connection between nap-time dreams and better memory in people who were learning a new skill.
In the study,99 college students between the ages of 18 and 30 each spent an hour on a compute, trying to get through a virtual maze（迷宫）.The maze was different place each time they tired—making it even more difficult. They were also told to find a particular picture of a tree and remember where it was.
For the first 90 minutes of a five-hour break, half of the participants stayed awake and an half were told to take a short nap .Participants who stayed awake were asked to describe their thoughts. Participants who took a nap were asked about their dreams before sleep and after sleep—and they were awakened within a minute of sleep to describe their dreams.
Stickgold, a neuroscientist（神经科学家）,wanted to know what people were dreaming about when their eyes weren＇t moving during sleep.
Four of the 50 people who slept said their dreams were connected to the maze. Some dreamed about the music that had been playing when they were working ; others said they dreamed about seeing people in the maze. When these four people tried the computer maze again, they were able to find the tree faster than before their naps.
Stickgold suggests the dream itself doesn‘t help a person learn—it＇s the other way around.He suspects that the dream was caused by the brain processes associated with learning.
All four of the people who dreamed about the task had done poorly the first time, which makes Stickgold wonder if the dreams show up when a person finds a new task particularly difficult. People who had other dreams, or people who didn＇t take a nap, didn＇t show the same improvement.
【小题1】Before having a short nap, participants of the experiment were asked to .
| A．stay in a different place in the maze |
| B．design a virtual maze which is difficult to get through |
| C．experience the experiment and try to remember something |
| D．get through a virtual maze on a computer from the same place |
| A．Participants who took a nap were required to express their thoughts. |
| B．Some dreams may encourage people to invent something new. |
| C．Participants who dreamed about films could finish the task more easily. |
| D．Participants whose dreams had something to do with the maze could find the tree faster. |
| A．every person may dream about what they learned |
| B．people＇s brain processes may still be connected with their learning in their dreams |
| C．once people＇s eyes stop moving, they are sure to dream about something |
| D．no matter how fantastical or boring, dreams are connected with people＇s life |
| A．Dreams Are Strange | B．Not All Dreams Are True |
| C．Dreaming Makes Perfect | D．Stickgold, a Dream Expert |

Wikipedia: The Online Know-It-All
If you want to find out a piece of information about anything, the best place to search for it is Wikipedia. The name “Wikipedia” is from the Hawaiian word wiki, meaning “quick”. This online encyclopedia (百科全书) is written by thousands of people around the world. Anyone with Internet access can write, add or make changes to Wikipedia articles if he or she finds it incorrect or not well written. In this way, people who know a lot about a certain subject can write about it even if they are not university professors. But contributions cannot damage Wikipedia because many experienced editors are watching pages and techies (技术专家) can write editing programs to keep track of or correct bad edits. Where there are disagreements on how to present facts, editors work together to arrive at an article that fairly represents current expert opinion on the subject.
Wikipedia is quite different from paper-based reference sources in important ways. Unlike printed encyclopedias, it is continually created and updated, with articles on historic events appearing within minutes, rather than months or years.
What’s more, Wikipedia includes articles written in about 285 languages. This fact makes it one of the few websites on the Internet that are truly international. It was started in 2001 by Larry Sanger and Jimmy Wales, as a free online English-language encyclopedia project. Since its creation, it has grown rapidly into one of the largest reference websites, attracting nearly 500 million unique visitors monthly. There are more than 77,000 active contributors working on more than 22,000,000 articles in different languages. As of today, there are 4,396,866 articles in English.
So, if you are looking for some information, why not try Wikipedia? It’s free, multilingual，and informative.

Until recently, the "science of the future" was supposed to be electronics and artificial intelligence. Today it seems more and more likely that the next great breakthroughs in technology will be brought through a combination of those two sciences with organic chemistry and genetic engineering. This combination is the science of biotechnology.
Organic chemistry enables us to produce marvelous synthetic materials. However, it is still difficult to manufacture anything that has the capacity of wool to conserve (保存) heat and also to absorb moisture. Nothing that we have been able to produce so far comes anywhere near the combination of strength, lightness and flexibility that we find in the bodies of ordinary insects.
Nevertheless, scientists in the laboratory have already succeeded in "growing" a material that has many of the characteristics of human skin. The next step may well be "biotech hearts and eyes" which can replace diseased organs in human beings. These will not be rejected by the body, as is the case with organs from humans.
The application of biotechnology to energy production seems even more promising. In 1996 the famous science fiction writer, Arthur C. Clarke, many of whose previous predictions have come true, said that we may soon be able to develop remarkably cheap and renewable sources of energy. Some of these power sources will be biological. Clarke and others have warned us repeatedly that sooner or later we will have to give up our dependence on non-renewable power sources. Coal, oil and gas are indeed convenient. However, using them also means creating dangerously high levels of pollution. It will be impossible to meet the growing demand for energy without increasing that pollution to catastrophic (灾难性的) levels unless we develop power sources that are both cheaper and cleaner.
It is attempting to think that biotechnology or some other "science of the future" can solve our problems. Before we surrender to that temptation we should remember nuclear power. Only a few generations ago it seemed to promise limitless, cheap and safe energy. Today those promises lie buried in a concrete grave in a place called Chernobyl, in the Ukraine. Biotechnology is unlikely, however, to break its promises in quite the same or such a dangerous way.
【小题1】According to the passage, the science of the future is likely to be ________.
| A．electronics | B．biotechnology |
| C．genetic engineering | D．nuclear technology |
| A．as good as wool |
| B．as good as an insect's body |
| C．better than natural materials |
| D．not as good as natural materials |
| A．to transplant human organs |
| B．to make artificial hearts and eyes |
| C．to produce drugs without side effects |
| D．to make something as good as human skin |
| A．Biological power will keep all its promises. |
| B．Biological power is cheaper than nuclear power. |
| C．Biotechnology can solve all our future energy problems |
| D．Biological power may not be as dangerous as nuclear power |

According to body language expert Robert Phipps，the way people sleep at night actually determines a lot about the type of personality they have.Phipps has identified four sleeping positions that affect personality.
Phipps found that worriers，those who stress the most，tend to sleep in the fetal(胎儿的)position.He found that this is the most common bedtime position，with nearly 58 percent of people sleeping on their side with knees up and head down.The more we curl up(蜷曲)，the more comfort we are seeking，according to Phipps.
The second most common position is the log.Sleeping with a straight body，with arms at each side，as if they are standing guard at Buckingham Palace，indicates stubbornness，and these people(the 28 percent who sleep this way)often wake up stiffer than when they went to sleep.
“The longer you sleep like this，the more rigid your thinking is and you can become inflexible，which means you make things harder for yourself，”according to Phipps.
Yearner(向往型)sleepers are next on the list.About 25 percent of people sleep in this style—on their side with arms stretched out in front，looking as if they are either chasing a dream or perhaps being chased themselves.Yearners are typically their own worst critics，always expecting the best results，explained Phipps.These people often wake up refreshed and eager to face the challenges of the day ahead.
Perhaps the most peculiar(奇怪的)of sleep styles is the freefaller position.This sleep style makes up 17 percent of the population.They sleep face down with arms stretched out.These people，according to Phipps，feel like they have little control over their life.Not only is this the strangest of sleep styles，but also the least comfortable，and people may wake up feeling tired and have no energy.
In conclusion，Phipps has only one more thing to add：“A good night's sleep sets you up for the following day and our sleeping positions can determine how we feel when we wake.”
【小题1】Which of the following is the best title of the passage?
| A．A Good Night's Sleep Sets You Up for the Following Day |
| B．Your Personality Depends a Lot on How You Sleep at Night |
| C．How You Sleep at Night Affects What You Do the Next Day |
| D．Which Sleeping Position Helps You Sleep Comfortably |
| A．stubborn | B．flexible |
| C．comfortable | D．strange |
