It's a fact that we all dream. Some dreams seem to last for hours, others only for seconds. Some of us have strange dreams, some have interesting dreams, and some of us have unpleasant dreams. Tests in the 1980s showed that these dreams occur within 90-minute cycles, each cycle made up of six stages. In the last stage people experience rapid eye movement, known as REM, and it is in this stage that dreaming takes place. Eighty percent of people who were woken during this sixth stage could easily remember their dreams. On the other hand, when during the first five stages (NREM), only seven percent could describe a dream.
However, of these same people woken during the first five stages, 74% were able to remember thinking activity, although they would not call it a dream. NerysDee, who has written about dreams in a book called "Your Dreams and What They Mean" says: "Perhaps during NREM sleep we are sorting out our outer mundane problems, but in REM sleep we are dealing with inside matters." She also makes the following statement about 90-minute cycle: It may also prove the reason why insomniacs who wake in the middle of the night find it impossible to get to sleep again for at least an hour and a half. In other words, until they have missed out one complete 90-minute sleep period.

A.Everyone dreams but very few can recall what they dream. |
B.Some people have long dreams and others have very short ones. |
C.People can only remember unpleasant dreams. |
D.More than eighty percent of people can remember their dreams. |

Men have always believed that they are smarter than women. Now, a study has found that while this is certainly true, men also have to deal with the fact that they are also more stupid than the fairer sex.
In the study, scientists measured the IQ of 2500 brothers and sisters and they found an uneven number of men not only in the top two percent, but also in the bottom two percent.
The study's participants were tested on science, maths, English and mechanical abilities.
Though there were twice as many men as women in the smartest group, there were also twice as many men among the dolts.
The aggregate scores of men and women were similar.
One of the study's authors, psychology professor Timothy Bates, said that the phenomenon may be because men have always been expected to be high achievers and women have been restricted to spend more time taking care of their home.
"The female developmental program may be tilted more towards ensuring survival and the safety of the middle ground.," the Daily Mail quoted Professor Bates, of Edinburgh University, as saying.
The research tallies with past results that men were more likely than women to receive first class University degrees or thirds and women secured the seconds.
It has been said that men are more ready to take risk when it comes to academics. Women have always found to be steadier in their learning.
A past study has shown that women are securing more firsts and seconds, while men are continuing to receive more thirds.
The argument for the change is that the increase of coursework at the cost of exams favors women's steady approach.
【小題1】The purpose of the passage is to tell us that ________.
A.man are smarter then women |
B.man are more stupid the women |
C.a(chǎn) new fact about the IQ of men and women has been found |
D.men are more likely to receive first class university degrees |
A.they are born stupid |
B.they have to spend more time to tale care of their home than men |
C.they don’t like to take risk |
D.they are not expected to be high achievers |

A.Women are steadier in their learning. |
B.men are more ready to take risk in everything |
C.women are securing more firsts and seconds |
D.women are doing much better in academy |
A.Why are men smarter than women? |
B.Why are men more stupid than women? |
C.How does the result go along with the past research? |

The art of reading fiction is largely a matter of inferring meanings. To infer means to understand facts which are not directly stated---only suggested. Inference is one of the commonest ways of knowing things: a child holds his knee and cries; this action implies his feeling; an observer infers that the child is hurt. To infer accurately in everyday life requires caution in observing; to infer skillfully in fiction requires caution in reading; both require disciplined imagination.
The short-story reader can expect to find certain basic elements in any story. For example, all stories involve a person or persons, in a particular setting, faced with a demand for a response. The response called for may be a physical action, such as defeating an adversary(對手) or escaping from a danger; or it may be a mental action, such as adjusting to others or within oneself. In either case, the short story is a description in two ways: first, it shows the motives for a given human action; second, it makes a point about the general human situation. Such descriptions, however, rather than being stated directly, usually are implied by the elements of the story.
When the reader of a story understands all the facts and their interrelationships, he is ready to infer the significance of the story as a whole---its comment on the human situation. This comment, or theme, is the seed from which the story grew. It is also the idea by which all the separate elements of the story are governed, while these in turn further shape and modify the theme. In addition to action, character, and setting, these elements include structure, mood, tone, and point of view.
Fiction reading requires an awareness of all the ways in which a story communicates. It also requires attention to detail. What the author provides is a network of points which serve as clues to his meaning. He invites the reader to develop the meaning by inference, actually to create much of the story himself and so make it part of his own experience.
【小題1】According to the author, "infer" means ________ .
A.knowingfactsbeyondthestatement |
B.lookingformoreevidencesforthestatement |
C.findingoutadifferentmeaningfromthestatement |

Have you ever wondered why birds sing? Maybe you thought that they were just happy.After all,you probably sing or whistle when you are happy.
Some scientists believe that birds do sing some of the time just because they are happy.However,they sing most of the time for a very different reason.Their singing is actually a warning to other birds to stay out of their territory
Do you know what a“territory”is? A territory is an area that an animal,usually the male,claims(聲稱)as its own.Only he and his family are welcome there.No other families of the same species(物種)are welcome.Your yard and house are your territory where only your family and friends are welcome.If a stranger should enter your territory and threaten you,you might shout.Probably this would be enough to frighten him away.
If so,you have actually scared the stranger away without having to fight him.A bird does the same thing.But he expects an outsider almost any time,especially at nesting(筑巢) season.So he is screaming all the time,whether he can see an outsider or not . This screaming is what we call a bird’s song,and it is usually enough to keep an outsider away.
Birds sing loudest in the spring when they are trying to attract a mate and warn others not to enter the territory of theirs.
You can see that birds have a language all their own.Most of it has something to do with attracting mates and setting up territories.
【小題1】Some scientists believe that most of the time birds’singing is actually .
A.a(chǎn) way of warning | B.a(chǎn)n expression of happiness |
C.a(chǎn)n expression of anger | D.a(chǎn) way of greeting |
A.A place where families of other species are not accepted. |
B.An area which a bird considers to be its own. |
C.An area for which birds fight against each other. |
D.A place where a bird may shout at the top of its Voice. |
A.Because they want to invite more friends |
B.Because they want to find outsiders around. |
C.Because their singing helps frighten outsiders away. |
D.Because their singing helps get rid of their fears. |
A.By comparing birds with human beings. |
B.By reporting experiment results. |
C.By describing birds’ daily fife. |

What makes humans smarter than other animals? We’ve got a bigger brain, of course. But when it comes to brains, is bigger always better?
Traditionally, scientists have thought that humans’ superior intelligence derived(源于)mostly from the fact that our brains are three times bigger than those of our nearest living relatives, chimpanzees. People even used to believe that because men have slightly larger brains than women that men are smarter.
This, however, is not the truth. Scientists at University College London in the UK have found that brain organization, and not brain size, is the key to the superiority of human intelligence, reported Live Science.
Through millions of years of evolution, our ancestors were constantly pushed to get smarter so that they could meet the demands of new environments. However, holding this growing intelligence in increasingly large brains was not the best choice because bigger brains require more energy to power. “This is when reorganization may come into play, ”said Christophe Soligo, a member of the London research team.
In the study, scientists looked at the brains of 17 species of primates(靈長目動物), including monkeys, apes and humans. They found that in the process of evolution, brains didn’t keep growing as a whole. Certain regions of the brain grew prior to others in response to species’ needs, and in this way they could make the best use of their limited brain space.
For example, when early humans were struggling to survive, the brain region in charge of using tools and finding food grew in size more than other regions. But in modern times, the prefrontal cortex(前額皮質(zhì))—the region in charge of social cognition(認知), moral judgments and goal-directed planning—grew more than the rest of the brain.
Think of the brain as a room. If a big room is poorly organized, it doesn’t necessarily store more stuff than a smaller one.
Paul Manger, professor at the University of the Witwatersrand, South Africa, explains this principle using the example of whales. He told Scientific American: “Whales have big brains, absolutely. But if you look at the actual structure of the brain, it’s not very complex. Brain size only matters if the rest of the brain is organized properly. ”
【小題1】It has recently been found that humans are smarter than the other animals mainly because .
A.they are a species of primates |
B.they have much larger brains |
C.their brain structure is more complex |
D.they were constantly pushed to get smarter |
A.the brain kept growing in size to adapt to new environments |
B.most regions of the brain didn’t change |
C.the prefrontal cortex grew more than the rest of the brain |
D.humans’ brains became increasingly simple so that humans could survive |
A.Gender makes a difference in intelligence. |
B.The size of the brain has nothing to do with intelligence. |
C.Species whose brain is organized properly tend to be smarter. |
D.Larger brains are usually organized better than smaller ones. |
A.by presenting research data |
B.by giving examples |
C.by making a comparison |
D.by analyzing cause and effect |

Two new studies suggest that modern running shoes could increase the risk of injuries to runners.
One study involved sixty-eight healthy young women and men who ran at least twenty-four kilometers a week. The runners were observed on a treadmill machine (跑步機). Sometimes they wore running shoes. Other times they ran barefoot (赤腳).
Researchers from the JKM Technologies company in Virginia, the University of Virginia and the University of Colorado did the study.
They found that running shoes create more stress that could damage knees, hips and ankle joints than running barefoot. They observed that the effect was even greater than the effect reported earlier for walking in high heels.
The study appeared in the official scientific journal of The American Academy of Physical Medicine.
The other study appeared in the journal Nature. It compared runners in the United States and Kenya. The researchers were from Harvard University in Massachusetts, Moi University in Kenya and the University of Glasgow in Scotland.
They divided the runners into three groups. One group had always run shoeless. Another group had always run with shoes. And the third group had changed to shoeless running.
Runners who wear shoes usually come down heel first. That puts great force on the back of the foot. But the study found that barefoot runners generally land on the front or middle of their foot. That way they ease into their landing and avoid striking their heel.
Harvard’s Daniel Lieberman led the study. He says the way most running shoes are designed may explain why those who wear them land on their heels. The heel of the shoe is bigger and heavier than other parts of the shoe, so it would seem more likely to come down first. Also, the heel generally has thick material under it to soften landings.
But the researchers do not suggest that runners immediately start running barefoot. They say it takes some training. And there can be risks, like running when your feet are too cold to feel if you get injured.
The study was partly supported by Vibram, which makes a kind of footwear that it says is like running barefoot. The findings have gotten a lot of attention. But the researchers say there are many problems in the way the press has reported in their paper. So they have tried to explain their findings on a Harvard Website.
【小題1】What’s the main idea of the passage?
A.Walking in high heels could cause less serious effects than running barefoot. |
B.Two new discoveries encourage people to run in high heels. |
C.Running in shoes is partly good to runners. |
D.Two new studies prove running without shoes is beneficial to runners in most cases. |
A.Toes. | B.Hips. | C.Feet. | D.Legs. |

The weather predictions for Asia in 2050 read like a story from a doomsday movie.
Many experts and green groups fear they will come true unless there is a united global effort to hold back greenhouse gas outpouring. In the decades to come, Asia---home to more than half the world’s 63 billion people-will change from one climate extreme to another, with tired farmers battling droughts, floods, disease, food shortages and rising sea levels.
“It’s not a pretty picture,” said Steve Sawyer, climate policy adviser with Greenpeace in Amsterdam. Global warming and changes of weather patterns are already occurring and there is more than enough carbon dioxide and other greenhouse gases in the atmosphere to drive climate change for decades to come.
Already, changes are being felt in Asia but worse is likely to come, Sawyer and top climate bodies say, and could lead to mass migration and widespread human disasters. According to predictions, icebergs will melt faster, some Pacific and Indian Ocean islands will have to evacuate(疏散) or build sea defenses, storms will become more intense and insect and water-borne diseases will move into new areas as the world warms.
All this comes with rising populations and demand for food, water and other resources. Experts say environmental worsening such as deforestation and pollution will probably enlarge the results of climate change.
In what could be a sign of the future, Japan was hit by a record of 10 typhoons and tropical storms this year, while two-thirds of Bangladesh, parts of Nepal and large areas of northeastern India were flooded, affecting 50 million people, destroying livelihoods and making tens of thousands ill.
The year before, a winter cold struck and a summer heat wave killed more than 2,000 people in India.
【小題1】This passage is mainly about .
A.what kind of weather we like best |
B.the weather predictions for Asia in the future and the reasons |
C.how to improve our environment |
D.that the world will not be suitable for us to live in |

Twothirds of the world's major rivers have now been disrupted with more than 50,000 dams in an attempt to store water and provide power.In the US,there are more than 85,000 dams,disrupting large and small rivers,and in most cases transforming natural flow.The most famous of these,the Hoover Dam,constructed in the 1930s,is mainly responsible for the fact that the Colorado River no longer reaches the ocean.
Dams,besides all their attractive benefits,also have negative impacts.Creating a reservoir means a large area must be flooded.Communities may lose their land,houses and culturally important sites.
Environmentally,the new reservoir can be a paradise for wildlife,especially birds;however,it can cause greenhouse gas emissions and poison the water.Also,the dramatic rise and fall of water levels during dam releases is too extreme for plants and animals to cope with,resulting in dead zones around the shores of reservoirs.Fish that lay their eggs in the shallows,for example,may find a few hours later that those sites are high and dry.
Downstream(在下游方向)of a dam,the flow may be reduced so that farmers cannot irrigate their fields.Many rivers run through national borders,which may cause conflict over precious water.Disputes have been continuing between India and Pakistan,and Turkey,Syria and Iraq,for example.
Dams don't just block the flow of water.They also prevent fish migrations,and dams are a barrier to sediment(沉淀物)flows.Instead of rushing downriver,sediments get backed up against the dam wall,which causes the reservoir level to increase over time.However,sediments which are rich in nutrients have become a problem.The fertility of the entire system can be influenced,with soils lost during seasonal rains not being replaced.
Perhaps the biggest problem can be seen in deltas,which are sinking into the oceans.Groundwater is being extracted to feed the city,causing the city to sink,and sediments washed away by the ocean are no longer being replaced.The result is that sea level rises in cities from Shanghai to Alexandria.
【小題1】The Hoover Dam is mentioned in the passage in order to show________.
A.dams play an important role in our life |
B.dams have impacted the flow of the rivers |
C.dams make people lose their land and houses |
D.dams have many benefits as well as side effects |
A.a(chǎn),c | B.c,e |
C.b,e | D.b,c |
A.will find more places to lay their eggs |
B.will face a dangerous habitat |
C.will be fed on more sediments rich in nutrients |
D.will find it easier to deal with the rise of water |
A.Their entire system will be influenced. |
B.The rainy season will last longer. |
C.They will lie below sea level in future. |
D.Rich soils will be washed away. |
A.Environmental loss of dams. |

Animals are considered to be endangered if the species is close to extinction throughout all or most of its environment. Animals become endangered for a variety of reasons.
Some animals become endangered when their habitats contain resources for humans. For example, commercial forest cutting in the Amazon Rainforest has seriously reduced the population of many animal species and lead to the extinction of other groups. Land itself is an important resource to humans since it provides us with living space, and when people replace animal habitats with human habitats, it can lead to larger loss of natural species.
Commercial and industrial operations may reduce land or water for animals and pollute their environment. Due to water pollution, the baiji, a fresh water dolphin native to China, was declared extinct, meaning it’s unlikely the population can recover. Even noise pollution from human activities can lead to the disorder of animal behavior.
Another cause that makes animals become endangered is over-fishing or over-hunting. Over-hunting whales led to near extinction of many species of whales.
The introduction of a non-native species to a habitat may make animals become endangered. The native species may not defend against a new one, and the effects can be dangerous. In Australia, the introduction of the common house cat led to the extinction of the red-fronted parakeet and has seriously damaged the populations of several small animals.
Introduced species can also bring new diseases with them. As a result, animals become endangered. Native animals may not have the power to fight against non-native diseases, and population levels can suffer. Another cause of disease is human-introduced chemicals. The use of DDT is believed to be one of the leading causes in driving the California Condor to near extinction.
When animals become endangered, the entire food chain can be affected. For example, in 2008 disease seriously harmed the honeybee, which is largely responsible for pollinating(授花粉) plants, including many fruits and vegetables. Without their pollination, a very large part of the human diet could be reduced. In fact, if the honeybee should become extinct, our life would be affected and billions of dollars would be lost. Therefore, many people argue that when animals become endangered it is in man’s own self-interest to protect them.
【小題1】The passage is mainly about ______.
A.ways of protecting animals’ habitats |
B.effects caused by species endangerment |
C.dangers of bringing in non-native species |
D.reasons why animals become endangered |
A.The extinction of the whales. |
B.The extinction of the red-fronted parakeet. |
C.The decreasing population of the dolphin. |
D.The effect of the honeybee on the human diet. |
A.Native species are likely to die from the new diseases. |
B.It’s hard for non-native species to survive. |
C.Non-native species will take up more space. |
D.Native species are so powerful for non-native species. |
A.loss of habitat | B.harmful chemicals |
C.forest cutting | D.unfamiliar diseases |
A.humans are to blame for species extinction |
B.small animals mean little to the whole food chain |
C.protection of the honeybee has cost billions of dollars |
D.humans protect animals for the benefit of themselves |
