1 Chimpanzees (黑猩猩) will soon be extinct (灭绝). If the present rate of hunting and habitat (栖息地) destruction continues, then within 20 years, there will be no chimpanzees living in the wild. But this is more than an environmental or moral tragedy
(悲剧). Chimpanzee extinction may also have profound implications (含意) for the survival of their distant relatives - human beings.
2 In 1975 the biologist Marie-Claire King and Allan Wilson discovered that the human and chimpanzee genomes (基因组) match by over 98%. Compare this to the mouse, used as model for human disease in lab tests, which shares only 60% of its DNA with us. In fact, chimpanzees are far more similar to humans than they are to any other species of monkey. As well as resembling us genetically, chimps are highly intelligent and able to use tools. These facts alone should be enough to make protection of chimps an urgent priority (优先). But there is another, more selfish reason to preserve the chimp.
3 The chimpanzees' trump card (王牌) comes in the field of medical research. Chimpanzees are so similar to humans that veterinarians (兽医) often refer to human medical textbooks when treating them. Yet chimpanzees do show differences in several key areas. In particular, chimps are much more resistant to a number of major diseases. It is this ability that is so interesting.
4 For example, chimps seem to show a much higher resistance than humans to HIV, the virus that causes AIDS. Indeed, their use as experimental animals in AIDS research has declined because they are so resistant.
5 By sequencing the chimp genome and pinpointing (找到) the place where the chimpanzee DNA sequence differs from that of humans, scientists hope to be able to discover which part of the genetic code gives chimps their increased resistance to some diseases. This, they hope, will allow them to develop new and more effective treatments for the human forms of these diseases. Such treatments could include the production of new drugs or even the alteration (
) of the human geneti

篇 Water
The second most important constituent (构成成份) of the biosphere (生物圈) is liquid water. This can only exist in a very narrow range of temperatures, since water freezes at 0℃ and boils at 100℃. Life as we know it would only be possible on the surface of a planet which had temperatures somewhere within this narrow range.
The earth's supply of water probably remains fairly constant in quantity. The total quantity of water is not known very accurately, but it is about enough to cover the surface of the globe to a depth of about two and three-quarter kilometers. Most of it is in the form of the salt water of the oceans - about 97 per cent. The rest
is fresh, but three-quarters of this is in the form of ice at the Poles and on mountains, and cannot be used by living systems until melted. Of the remaining fractional which is somewhat less than one per cent of the whole, there is 10-20 times as much stored underground water as there is actually on the surface. There is also a tiny, but extremely important fraction of the water supply which is present as water vapor in the atmosphere.
Water vapor in the atmosphere is the channel through which the whole water
circulation (循环) of the biosphere has to pass. Water evaporated (蒸发) from the surface of the oceans, from lakes and rivers and from moist (潮湿的) earth is added to it. From it the water comes out again as rain or snow, falling on either the sea or the land. There is, as might be expected, a more intensive evaporation per unit area over the sea and oceans than over the land, but there is more rainfall over the land than over the oceans, and the balance is restored by the runoff from the land in the form of rivers.
31 Liquid water only exists
A in the center of the earth.、B on the surface of our planet.
C in the coastal areas of the earth.、D in a very narrow range of temperatures. 32 The total quantity of water on Earth
A has greatly increased in recent years.、B remains almost unchanged. C is decreasing constantly.、D is affected by global warming. 33 Most of the fresh water on Earth
A is in the form of ice at the Poles and on mountains
B is stored underground.、C is found in rivers and lakes. D comes from the rain.
34 The word \
A a large area.、B a very small amount.、C an important system. D a major source of information 35 There is more of rainfall
A over the mountains than over the rivers.、B over the rivers than over the mountains、C over the land than over the oceans.、D over the oceans than over the land.
篇Mind-reading Machine
A team of researchers in California has developed a way to predict what kinds of objects people are looking at by scanning (扫描) what's happening in their brains.
When you look at something, your eyes send a signal about that object to your brain. Different regions of the brain process the information your eyes send. Cells in your brain called neurons (神经元) are responsible for this processing.
The fMRI (functional Magnetic Resonance Imaging) (功能性磁振造影) brain scans could generally match electrical activity in the brain to the basic shape of a picture that someone was looking at.
Like cells anywhere else in your body, active neurons use oxygen. Blood brings oxygen to the neurons, and the more active a neuron is, the more oxygen it will consume. The more active a region of the brain, the more active its neurons, and in turn, the more blood will travel to that region. And by using fMRI, scientists can visualize (使?显现) which parts of the brain receive more oxygen-rich blood - and therefore, which parts are working to process information.
An fMRI machine is a device that scans the brain and measures changes in blood flow to the brain. The technology shows researchers how brain activity changes when a person thinks, looks at something, or carries out an activity like speaking or reading. By highlighting the areas of the brain at work when a person looks at different images, fMRI may help scientists determine specific patterns of brain activity associated with different kinds of images.
The California researchers tested brain activity by having two volunteers view hundreds of pictures of everyday objects, like people, animals, and fruits. The scientists used an fMRI machine to record the volunteers' brain activity with each photograph they looked at. Different objects caused different regions of the volunteers' brains to light up on the scan, indicating activity. The scientists used this information to build a model to predict how the brain might respond to any image the eyes see.
In a second test, the scientists asked the volunteers to look at 120 new pictures. Like before, their brains were scanned every time they looked at a new image. This time, the scientists used their model to match the fMRI scans to the image. For example, if a scan in the second test showed the same pattern of brain activity that was strongly related to pictures of apples in the first test, their model would have predicted the volunteers were looking at apples.
36 What is responsible for processing the information sent by your eyes? 、A The magnetic system in the brain.、B The central part of the heart. C Neurons in the brain.、D Oxygen-rich blood.
37 The function of an fMRI machine is
A to show how neutrons take in oxygen-rich blood. B to measure how dense the blood is in the brain.
C to identify which parts of the brain are processing information、D to record how much oxygen the brain consumes.
38 The expression \A marking the parts of the brain that are processing information.
B giving light to the parts of the brain that are processing information. C putting the parts of the brain to work.
D preventing the parts of the brain from working. 39 The researchers experimented on
A animals and objects.、B fMRI machines.、C thousands of pictures. D two volunteers.
40 Which of the following can best replace the title of the passage?
A Your Thoughts Can Be Scanned.、B Recent Development in Science and Technology、C A Technological Dream.、D An Intelligent Robot.
篇Youth Emancipation in Spain
The Spanish Government is so worried about the number of young adults still living with their parents that it has decided to help them leave the nest.
Around 55 percent of people aged 18-34 in Spain still sleep in their parents' homes, says the latest report from the country's state-run Institute of Youth.
To coax (劝诱) young people from their homes, the Institute started a \
Emancipation (解放)\
Economists blame young people's family dependence on the precarious (不稳定的) labor market and increasing housing prices. Housing prices have risen 17 percent a year since 2000.
Cultural reasons also contribute to the problem, say sociologists (社会学家). Family ties in south Europe - Italy, Portugal and Greece - are stronger than those in middle and north Europe, said Spanish sociologist Almudena Moreno Minguez in her report \ Key for Understanding\
\ir private life is organized,\
In Spain - especially in the countryside, it is not uncommon to find entire groups of aunts, uncles, cousins, nieces and nephews (外侄/侄子) all living on the same street. They regularly get together for Sunday dinner.
Parents' tolerance is another factor. Spanish parents accept late-night partying and are wary of setting bedtime rules.
\call the father a fascist,\ sociologist at Carlos III University in Madrid.
Mothers' willingness to do children's household chores (家务) worsens the problem. Dionisio Masso, a 60-year-old in Madrid, has three children in their 20s. The eldest, 28, has a girlfriend and a job. But life with mum is good.
\
41 The \ A live in an independent way.、B fight for freedom.
C fight against social injustice.、D get rid of family responsibilities.
42 It can be inferred from paragraph 5 that family ties are stronger in Portugal than in A Greece.、B Finland.、C Spain.D Italy.
43 Young people's family dependence can be attributed to all the following factors EXCEPT
A parents' tolerance.、B housing problems.、C unwillingness to get married. D cultural traditions.、、
44 Which of the following statements is NOT true of Dionisio Masso? A、She has a boyfriend.、B、She is 60 years old.
C、She has three children.、、D、She lives in Madrid.
45 The phrase \ A tired of.、B afraid of.、C worried about.、D cautious about.

Reduce Packaging
Pressure increased recently on British supermarkets and retailers to reduce
packaging as part of an anti-waste campaign. (46) Britain generates 4.6 million tons of
household waste every year by packaging.
Dozens of people have expressed anger at the excess of plastic wrapping.
Campaigners have called on Britain to learn from other European countries. (47) When returned bottles are put in a vending machine (自动售货机), the deposit is refunded. Environmentalists
warn that Britain lags behind in this.
There were reports of growing unease among consumers over the amount of packaging they have to de
al with. Trade standards officers also object to excessive
packaging. (48)
In response to a campaign by Britain's The Independent newspaper, leading
supermarkets have pointed to various initiatives to win the public confidence. (49)
But campaigners said retailers and the government could learn much from anti-waste practices on t
he Continent. In Sweden, non-recyclable batteries have been
taxed since 1991 to encourage a switch to alternatives. (50) In Germany, plastic bags are unheard of in supermarkets and deposits are paid for reusable plastic and glass beverage bottle
