For centuries, people have wondered about the strange places that they seem to visit in their sleep. ___【小题1】___ However, they have been valued as necessary to a person’s health and happiness.
Historically people thought dreams contained messages from God. It was only in the twentieth century that people started to study dreams scientifically believing that they tell about a person’s character. ___【小题2】__ He believed that dreams allow a person to express fantasies or fears, which would be socially unacceptable in real life.
The second theory to become popular was Carl Jung’s compensation theory. Jung, a former student of Freud, said that the purpose of a dream is not to hide something, but rather to communicate it to the dreamer. ___【小题3】__ Thus, people who think too highly of themselves may dream about falling; those who think too little of themselves dream of being heroes.
Using more recent research, William Domhoff from the University of California found that dreaming is a mental skill that needs time to develop in humans. ___【小题4】___  Until they reach age five, they can not express very well what their dreams are about. Once people become adults, there is little or no change in their dreams. The dreams of men and women differ.
The meaning of dreams continues to be difficult to understand. ___【小题5】___ If you dream that a loved one is going to die, do not panic. The dream may have meaning, but it does not mean that your loved one is going to die.

A．Dreams make up for what is lacking in waking life.

B．However, people should not take their dreams as reality.

C．They have been considered as meaningless nighttime journeys.

F．They think their mind is trying to tell them something.
G．First, there was Sigmund Freud’s theory.

Alan Izhar-Bodner, an Israeli inventor, has developed a swimming suit for divers to breathe underwater without carrying heavy oxygen tanks. His suit makes use of the air that is dissolved（溶解）in water, just like fish do.
The system uses the Henry Law which states that the amount of gas that can be dissolved in a liquid is proportional (成比例的)to the pressure on the liquid. Raise the pressure ---more gas can be dissolved in the liquid. Decrease the pressure --- less gas dissolved in the liquid releases the gas. This is exactly what happens when you open a can of soda; carbon dioxide gas is dissolved in the liquid and is under pressure in the can. Open the can, releasing the pressure, and the gas fizzes(嘶撕作响)out.
Bodner's System obviously uses a special machine to lower pressure in part of a small amount of seawater taken into the system; dissolved gas is taken out. The patent（专利）reads: A self-contained open-circuit（循环）breathing instrument for use within a body of water naturally containing dissolved air. The instrument is adapted to provide breathable(可吸入的)air. The instrument contains an inlet for taking out a quantity of water from the body of water. It further contains a separator for separating the dissolved air from the quantity of water, thus gaining the breathable air. The instrument further contains an outlet for expelling (驱逐)the separated water back into the body of water, and another outlet for removing the breathable air and supplying it for breathing. The air is supplied so as to enable it to be expelled back into the body of water after it has been breathed .   
Human beings have been thinking about how to breathe underwater since they started swimming. This long-held desire plays an important part in one of the first great science fiction novels, Jules Verne's 20,000 Leagues Under the Sea.
【小题1】It can be inferred from the passage that____________ .

A．the less pressure it is, the less carbon dioxide gas is dissolved in the liquid

B．the deeper one dives into the ocean, the less gas is dissolved in the water

C．the greater pressure it is, the more carbon dioxide gas is dissolved in the liquid

D．the deeper one dives into the ocean, the more gas is dissolved in the water

【小题2】This passage is mainly about __________.

A．how Bodner invented the instrument for breathing underwater

B．why Bodner invented the instrument for breathing underwater

C．how Bodner's instrument for breathing underwater works

D．how Bodner's instrument is used by divers for breathing underwater

【小题3】From the passage we learn that __________.

A．a separator is used to expel breathable air back into the body of water

B．a separator is used to separate the air from the water so as to make use of the water

C．The breathable air removed from an outlet will eventually go back to the body of water.

D．The breathable air removed from an outlet will immediately go back to the body of water.

If there is one thing I’m quite sure about, it is that in a hundred years from now we still be reading newspapers. Not those newspapers are a necessity. Even now some people get most of the news from the television or have the radio switched on in the background or in the car. Many buy a paper only on Saturday or Sunday. But for most people a newspaper has become a habit passed down from generation to generation.
The basic British character won’t change, and one of the characteristics of the British is that we don’t much like talking to each other when we get up. So what better way is there to keep yourself thinking in the morning than to wrap yourself in a newspaper?
Over the past couple of centuries, human beings have developed a close relationship with the newspaper. It has become as natural as breathing or enjoying the sun. And it is not just the British who love newspapers. On suburban trains in Calcutta, for instance, just one person in the whole car will buy a newspaper and read aloud the best bits to his fellow passengers, much to everybody’s enjoyment.
The nature of what is news may change. What essentially makes news is what affects our lives and the big political stories, the coverage of the wars, earthquakes and other disasters, will continue much the same. I think there will be more coverage of scientific research, though. It’s already happening in areas that may directly affect our lives, like genetic engineering. In the future I think there will be more coverage of scientific explanations of why we feel as we do, whether it’s love or depression. We develop a better understanding of how the brain operates and what our feelings really are.
It’s quite possible that in the next century newspaper will be transmitted(传送) electronically from the national equivalents of Fleet Street (伦敦的舰队街，以报馆集中而著称) and printed out in our own homes. In fact, I’m pretty sure that that is how it will happen in future. You’ll be probably selecting from a menu, making up your own bespoke newspaper by picking out the things you want to read and say. You might even have an intelligent screening device (装置) to do the job for you.
I think people have got it wrong when they talk about the competition between the different media. They actually have a relationship, feeding off each other. It was once predicted that television would kill off newspapers, which hasn’t happened. What is read on the printed page is more enduring (持久的) than pictures on a flickering screen or sound lost in the sky. And as for the Internet, it’s never really satisfying to read something just on a screen.
【小题1】The author of the passage is most probably from _______________.

A．Russia

B．India

C．Britain

D．America

【小题2】According to the passage, the future of newspapers ____________.

A．will be mainly connected with scientific research

B．will report more important political activities

A．a newspaper which dares to report the truth

B．a newspaper edited to one’s own interest

C．a newspaper edited and published for the public

D．a newspaper which only covers the life of family members

【小题4】Which of the following is TRUE according to the passage?

A．It was centuries ago that newspapers came into being .

B．Televisions have taken the place of newspapers .

C．The Internet will gradually take the place of newspapers.

D．The nature of news may remain the same over generations.

Do you know blood types?
Special care must be taken in selecting new blood for a badly injured person, who would be killed by the transfusion (输血) if the blood is too different from his own.
There are four basic types of blood A. B. A B. and O. Blood type, like hair and height, comes from parents. Basically, A and B can not be mixed. AB, sometimes called the universal recipient (万能受血者), may receive A or B,. O type, often called the universal donor (万能输血者), gives his blood to any other group. Patients usually receive nothing, but salt or plasma (血浆) until their blood can be matched as exactly as possible in the blood bank of a hospital. There is a relationship between your blood type and your nationality (国籍). Among Europeans, about 42 % have type A while 45 % have type O. The fewest is the type B.
【小题1】Which of the following show the correct relationship in blood transfusion ("→"means giving blood to...)?
   

A．

B．

C．

D．

【小题2】Usually person who has been injured and lost too much blood should be given a blood transfusion______.

A．after he receives salt and plasma	B．before he feels uncomfortable
C．when the new blood fits his body	D．as soon as accident happens

【小题3】From this passage we can know that among Europeans ______ 13 % have the type B.
A. about 　　B. no more than 　　C. less than 　　D. at most

How Do Animals Catch their ZZZ's（打鼾声）？
Different creatures have developed some pretty creative ways to get their rest and stay safe． The lizard likes to sleep at the far end of small branches hanging out over a pond or lake in the rain forest． If a snake tries to slither up the branch to eat it, it will shake the branch and knock the lizard off, and the lizard will fall safely into the water． Chameleons can change color to match their surroundings in order to hide even while sleeping．
Gorillas like to sleep high in the trees． They build a new bed every night, sometimes taking up to half an hour to pile branches, twigs, and leaves into a comfortable bed． Birds also find it safe to sleep in the trees, but unless they have eggs or young chicks, they don't use a nest． They just lock their feet around a branch and hang on． A special tendon in their legs is automatically tight when they are at rest, so they won't let go and fall．
Dolphins live underwater, but must come to the surface to breathe． Scientists now believe that dolphins may sleep with only half their brain, while the other half stays awake to keep them safe and breathing． Seals also do this, lying on their sides on the surface of the water with one flipper underwater paddling to keep their noses above the surface． Some ducks may also have this ability, and actually sleep with one eye closed and one eye open．
【小题1】How does a chameleon protect itself while sleeping?

A．By changing its body colors

B．By hanging out over a pond．

C．By sleeping with half their brain．

D．By making beds with branches．

【小题2】Why will not birds fall when they are at rest?

A．They build nests and sleep in them．

B．They fall asleep automatically．

C．They have a loose tendon in their legs．

D．They lock their feet around a branch．

【小题3】How do dolphins breathe?

A．They breathe underwater．

B．They come to the surface to breathe．

C．They breathe underwater or come to the surface to breathe．

D．We don't know．

【小题4】What does the writer intend to tell us?

A．The cleverest animal is the gorilla because it can make beds．

B．Differences in habitat can lead to different living habits．

C．The ways animals catch their ZZZ's are pretty much the same．

D．In order to protect themselves most animals choose not to sleep

A 70-year study of personality suggests that pessimism is a risk factor for early death, especially among men.
　　The study results also indicate that pessimism can be linked to increased risk for sudden death from accidents or violence, according to the report published in the March issue of Psychological Science.
　　Christopher Peterson of the University of Michigan and his colleagues analyzed data from the Terman Life-Cycle Study, which began by studying California public-school children with high IQs in 1921 and followed them through their life. Most of the 1,528 children were teenagers when the study began. Those still living are now in their 80s. In 1936 and 1940, participants were asked to complete a questionnaire designed to obtain information about difficult life events and their effect on overall outlook. One such question was, “What do you regard as your most serious fault of personality or character?”
　　Pessimists were defined as fatalistic(宿命论的)people who tend to blame themselves when things go wrong and who believe that one bad event can ruin the rest of their life. They also tend to expect bad things to happen to them and feel that they have little or no ability to change their situation.
　　Males were more likely than females to be classified as pessimistic. Compared with individuals with a more cheerful and optimistic outlook, pessimists were more likely to die from accidents and violence (including suicide).
　　A pessimistic personality may lead to poor problem-solving ability, social difficulties and risky decision-making. Taken together, these variables put the pessimist at higher risk of untimely(不适时的) death, say the researchers. Such a person is less likely to avoid or escape potentially dangerous situations, the researchers concluded. “A pessimistic way of thinking in which people worry too much about bad events, predicts untimely death decades later,” according to Peterson.
【小题1】According to the passage, you may be a pessimistic person, if one failure makes you feel________.

A．other people have been unfair to you.

B．other people will help you.

C．you cannot change a bad situation.

D．you can do better next time.

【小题2】According to the passage, pessimists may feel all of the following EXCEPT________

A．helpless when faced with difficulties.

B．cheerful when faced with troubles.

C．hopeless when one bad event occurs.

D．guilty when things go wrong.

【小题3】Which of the following statements is true, according to the passage?

A．Pessimists believe that everything in life depends on fate.

B．There are more pessimists among women than among men.

C．Most pessimists will end up committing suicide.

D．All pessimists will eventually die from accidents.

【小题4】The Terman Life-Cycle Study is a research program that studies________.

A．people over 70 years old.

B．people since their childhood.

C．pessimistic people over 80 years old.

D．only younger people.

【小题5】The analysis made by Christopher Peterson and his colleagues shows that pessimistic people________

A．will die from violence if they learn to be optimistic.

B．will more likely die from violence than optimistic people.

C．will die from violence because their IQs are low.

D．will die untimely if they are not able to learn to be cheerful and optimistic.

Animals can move from place to place, but plants cannot. When an animal is under attack, it can run away or fight back. Plants certainly cannot run away, and they lack teeth and claws. But plants can defend themselves by using both physical and chemical means.
Some plants have their own ways to keep animals away. For example, the leaves of the holly plant have sharp spines (刺) that discourage grass-eating animals. Holly leaves on lower branches have more spines than leaves on upper branches. This is because the lower leaves are easier for most animals to reach.
Some plants, such as the oak tree, have thick and hard leaves that are difficult for animals to eat. Some grasses may contain a sandy material; eating such grasses wears down the animal's teeth.
Many plants also have chemical defenses. Some plants produce chemicals that taste bitter or cause an unpleasant reaction. Some plants may fight against an attack by increasing the production of these chemicals. When a caterpillar (毛虫) bites a tobacco leaf, the leaf produces a chemical messenger. This messenger sends to the roots the information to produce more nicotine. The higher levels of nicotine discourage the caterpillar.
Many plants depend on both physical and chemical defenses. A certain plant in China, for instance, has prickly (多刺的) leaves, and each prickle contains poisonous venom (毒液). A single experience with this kind of plant will teach an animal to stay away from it in the future.
【小题1】The holly plant has more spines on the lower leaves because most animals________.

A．are not tall enough	B．like the lower leaves only
C．are not clever enough	D．can get the lower leaves easily

【小题2】To defend themselves, oak trees use________.

A．chemical means	B．physical means
C．bitter chemicals	D．sandy materials

【小题3】How does tobacco protect itself against an attack from a caterpillar?

A．Its leaves fight against the attack by physical means.

B．Its roots send a messenger to discourage the caterpillar.

C．Its roots increase the production of nicotine when it is attacked.

D．Its leaves produce poisonous sand to drive the caterpillar away.

【小题4】What would be the best title for this passage?

A．Plants and Animals	B．How Plants Defend Themselves
C．Attacks and Defenses	D．How Animals Eat Plant Leaves

SEE a cell phone cover that you like on Taobao? Forget about placing an order, paying the bill online and waiting for days for it to be delivered to you. In the near future, you'll be able to get it in minutes just by hit­ting "print" on your computer.
You might find it hard to believe that you could actually "print" an object like you would a picture. But it is not that hard to under­stand how it would work. Just as a traditional printer sprays (喷) ink onto paper line by line, modern 3-D printers spread material onto a surface layer by layer, from the bottom to the top, gradually building up a shape.
Instead of ink, the materials the 3-D printer uses are mainly plastic, resin (树脂)and certain metals. The thinner each layer is --- from a millimeter to less than the width of a hair ---  the smoother and finer the object will be.
This may sound like a completely new technology, but the truth is that 3-D printing has been around since the late 1980s. Back then, it was barely affordable for most people, so few knew about it.
Last year, though, saw a big change in the 3-D printing industry--- printers became much cheaper. For example, 10 years ago a desktop 3-D printer might have cost £20,000 (200,000 yuan), while now they cost only about £ 1,000, according to the BBC.
Taken out of the factory and in­troduced to more diverse and com­mon uses, 3-D printing can create just about anything you can think of ---flutes (笛子), bikinis, jewelry, aircraft parts and even human organs. In fact, scientists from Cornell Univer­sity in New York have just made an artificial ear using a 3-D printer, accord­ing to Science Daily. The fake ear looks and acts exactly like a natural one.
However, as 3-D printing becomes more commonplace, it may bring about certain problems --- such as piracy. "Once you can download a coffee maker, or print out a new set of kitchen utensils (餐具) on your personal 3-D printer, who will visit a retail (零售的) store again?" an expert in 3-D printing told Forbes News. Even more frightening, what if anyone in the world could use a 3-D printer to print out a fully functioning gun?
【小题1】According to the article, in the future, the 3-D printing technology will ___.

A．enable people to make better purchases online

B．be applied as widely in our daily lives as computers

C．change the way we make many products

D．shorten the time it takes for people to get what they buy online

【小题2】What was the big event happening in the 3-D printing industry last year?

A．The 3-D printing technology was taken out ofthe factory.

B．The 3-D printer became more affordable forconsumers.

C．The 3-D printer was used for medical treatmentfor the first time.

D．3-D printing technology began to be used invarious fields.

【小题3】How is the last paragraph developed?

A．By analyzing a cause and an effect.	B．By making comparisons.
C．By giving examples.	D．By presenting research findings.

【小题4】What is the best title of the passage?

A．Printing out everything	B．Technology in the future
C．Online shopping disappearing	D．Great demand for 3-D printers

Looking for some inspiration or the “write” kind of ideas for your creative stories? To start with, some writers describe winter by using their five senses or their imagination. Others write on their favorite winter activity. Whatever you choose to write about, working on a winter story can always help to improve your writing skills. Now read the following story and see if it helps get rid of any icy writing block you’ ve been struggling with.
A Winter Adventure 
Beep, beep. Beep-beep: the alarm clock rang. Slowly, I got out of warm bed down onto the wooden floor which the winter had thrown its cold upon. The bitter cold temperature penetrated   （穿透）my socks and I hurried to put my feet in shoes.
Looking out of the window, I watched the white snow, soft and thick, drop onto rooftops and trees. Half an hour later, finishing the last of my hot chocolate, I prepared to enter the adventure that waited for me outside. I buttoned my jacket and fastened my boots. Hat on, I opened the door and was greeted by the winter coldness.
In the depths of winter, the early morning did not have the rush of the rest of the year. Most of my neighbours were put off by the cold, and stayed in bed until the sun had climbed higher into the sky.
Unseen by those who remained locked inside their homes, warm in their beds, I enjoyed being alone with the beauty of the wintertime. Those indoors were unable to appreciate the snow-scapes, ice crystals, frost and the crisp（清新的）breeze. For them, the coming of winter meant just the arrival of the cold.
Appreciation depends on contrasts. One cannot love the warmth of April if one has not known the freezing cold of winter. Later that year, the heat of the sun on my skin would be all the more wonderful for my memories of that cold morning and others like it.
【小题1】The underlined word “adventure” refers to____________.

B．To show readers how to work on a winter story.

C．To inspire readers to take more exercise in winter

D．To tell readers how to appreciate the beauty of winter.

American researchers found females are the more talkative sex because of a special “language protein(蛋白质)” in the brain.
The study, conducted by neuroscientists （神经学家）and psychologist from the University of Maryland, concluded that women talked more because they had more of the Foxp2 protein. The research, published in the Journal of Neuroscience, found that higher levels were found among humans that were women but in rats that were males. Their findings came after it was previously claimed that ladies speak about 20,000 words a day – over 13,000 more than men. "This study is one of the first to report a sex difference in the expression of a language-associated protein in humans or animals,” said Prof Margaret McCarthy, who led the study. In their study, the researchers attempted to determine what might make male rats more vocal than their female friends.
They separated four-day-old rats from their mothers and then counted the number of times they cried out in the “ultrasonic range”, the frequencies higher than humans can hear, over five minutes. While both sexes called out hundreds of cries, the males called out twice as often, they found. But when the pups were returned to their mother’s cage, she fussed over her sons first. Tests conducted on the parts of the brain known to be associated with vocalcalls showed the male pups have up to twice as much Foxp2 protein as the females. The researchers then increased the production in the brains of female pups and reduced it in males. This led to the female rats crying out more often and their mothers showing more interest to them. In contrast, males became less “talkative”.
The researchers then tested samples from ten children, aged between three and five, which showed that females had up to 30 per cent more of the Foxp2 protein than males, in a brain area key to language in humans.
“Based on our observations, we assume higher levels of Foxp2 in girls and higher levels of Foxp2 in male rats is an indication that Foxp2 protein levels are associated with the more communicative sex,” said Prof McCarthy.
"Our results imply Foxp2 as a component of the neurobiological basis of sex differences in vocal communication in mammals."
【小题1】From the second paragraph, we can learn that ________.

A．women always speak more words than men

B．men and male rats have low levels of language protein

C．women and male rats have similar levels of Foxp2

D．McCarthy isn’t the first to find females more talkative

【小题2】The underlined phrase “fussed over” in the third paragraph probably means______.

A．paid attention to

B．related to

C．put pressure on

D．counted on

【小题3】The researchers carried out the experiments on rats in order to _______.

A．test which part of the brain is key to language in rats and humans

B．prove the levels of Foxp2 protein in humans and rats are different

C．determine the reason why female rats are more talkative than male rats

D．discover the association between Foxp2protein and vocal communication

【小题4】Which of the following can be the best title for the passage ?

A．Tests on humans and rats	B．Why women are the talkative sex
C．Sex differences in Foxp2 protein	D．Foxp2 protein determines oral ability
