8．The Scottish countryside will soon be home to creatures which are strange to Britain．This spring，17beavers will be released into a remote area of rivers and forests．Hunted to die out throughout Europe，beavers haven't roamedin Britain's wilderness for almost 500years．Ecologists would like to invite back other long-lost animals to help recover the natural balance．To save the country's plants from deer，which have doubled to 2million since the start of this decade，an Oxford University biologist late last year called for introducing the lynx（猞猁） that died out in Britain 1，300years ago．
Nature has long been a popular cause in Europe．British people love their countryside of fences and fields，and the Germans love their hiking forests．But in recent years people have set their sights on the more distant past，when Europe's forests were filled with elephants，rhinoceroses and big cats．Some people are even now advocating a return to the way of wilderness that dates back to the Pleistocene era，more than 11，000years ago．
Nobody is advocating allowing elephants and lions to run crazily in big cities．But supporters would give free control to a long list of small mammals，including the beaver and lynx，which some people fear could be dangerous．Some landowners are worried at the thought of beavers cutting down trees and possible floods； the Scottish parliament refused several earlier efforts to introduce the mammal．Proposals to set wolves and bears free in Britain have also met with opposition．
Although the beavers and the lynxes were popular in Europe thousands of years ago，no one is sure what effect they would have on ecosystems now．"The idea of bringing back big animals is interesting，but when you take it seriously，there are a lot of questions，"say some biologists．For example，elephants could destroy what little forest and grassland Europe has left．
The beavers of Tierra del Fuego provide a lesson．When a failed commercial fur farm released its few remaining beavers into the wild 60years ago，the population exploded，and are still harming the local people．Is this Britain's future？Supporters say no，the beaver will fit right in．Destroying nature is not a job for the wild．

41．The underlined word"roamed"most probably meansA
A．walked
B．released
C．developed
D．exploded
42．Why did the Oxford University biologist call for introducing the lynx？B
A．Because the lynx died out in Britain 1，300years ago．
B．Because the lynx can prevent the plants from being destroyed by deer．
C．Because there are too many deer in Britain．
D．Because the biologist wanted to invite back the long-lost species．
43．What can we learn from Para.3？C
A．Not all the people support setting loose wild animals in Britain．
B．Some small mammals will be out of control in Britain．
C．The landowners don't like beavers because of the possible disasters．
D．British Parliament has proposed several times to bring beavers back．
44．What is the opinion of the biologists about bringing back the mammals？B
A．They consider bringing them back to be fantastic．
B．They think bringing them back is no easy task．
C．They know for sure the result of bringing them back．
D．They think the mammals will destroy the ecosystem．
45．What can be inferred from the passage？B
A．Beavers are the most useful mammals to the balance of Britain．
B．Lynxes may get more freedom in Britain than tigers do．
C．The ecosystem in Britain doesn't need any changes．
D．Beavers released in Britain will destroy nature．

7．Climate change could affect food supplies，water resources，human health and homes．
If greenhouse gas emissions keep increasing at the current rate，global temperature is expected to rise between 2°C and 6°C by 2100．This doesn't sound much，but a 5°C change is the difference between the current warm period and an ice age．
Global warming leads to other changes in the climate：melting ice，more evaporation（蒸发），changes in geographical patterns of rainfall，heavier downpours separated by longer dry spells，more frequent heat waves，more intense hurricanes，and sea level rise．
These changes could affect crop growth as drought，increased evaporation and shrinking glaciers（冰川）disrupt water supply．Some crops could suffer heat stress．While there may be benefits in some regions，overall climate change is likely to have a negative impact on global food supplies．The impacts of climate change on agriculture will vary widely around the world．A global temperature rise of 1-2°C is expected to increase food production in some regions，particularly mid-latitude areas．But in tropical regions even a small amount of warming could reduce crop yields．A temperature rise of 3°C or more could threaten global food resources，as all regions are likely to experience negative impacts overall．
Freshwater resources could also diminish，especially in tropical regions，as rain patterns change and evaporation speeds up．Some communities could lose essential melt water as glaciers disappear，while more intense rainfall and hurricanes could cause more flooding，leading to water pollution and bacterial diseases such as cholera（霍乱）becoming more widespread．
Climate change could lead to a variety of health impacts-both positive and negative．On the negative side，scientists anticipate more cases of malnutrition，heatstroke and waterborne diseases such as cholera．Although some populations will benefit from a reduced risk of cold-related illnesses such as hypothermia，overall a warming world is likely to have negative effects on human health．
Scientists also expect damage to homes and buildings from more intense hurricanes，heavier rainfall and rising sea levels．Climate change is likely to affect infrastructure by increasing the risk of both coastal and inland flooding around the world，owing to a combination of heavier rainfall，rising sea levels and increased storm damage．Homes and buildings could also be affected by the thawing of frozen ground and greater risk of forest fires．
The consequences of climate change will have an impact on people around the world．

67．With global temperature increased by 1-2°C，D．
A．crops yields could be increased in tropical regions
B．food production could rise throughout the world
C．chances are that food resources would be threatened overall
D．mid-latitude areas are likely to experience positive impacts
68．The underlined word"hypothermia"in Paragraph 6 possibly means a serious medical condition caused byA．
A．lower temperature than normal
B．higher temperature than normal
C．more cases of malnutrition
D．cases of waterborne diseases
69．According to the passage，climate change has both positive and negative effects onC．
A．food supplies and buildings
B．freshwater resources and homes
C．human health and food supplies
D．human health and homes
70．The passage is mainly meant to tell usB．
A．how global warming leads to changes in the climate
B．how climate change affects people worldwide
C．why climate change affects our crop growth
D．why climate change contributes to all bad results．

10．One day，when I was working as a psychologist in England，an adolescent boy showed up in my office．It was David．He kept walking up and down restlessly，his face pale，and his hands shaking slightly．His head teacher had referred him to me．"This boy has lost his family，"he wrote．"He is understandably very sad and refuses to talk to others，and I'm very worried about him．Can you help？"
I looked at David and showed him to a chair．How could I help him？There are problems psychology doesn't have the answer to，and which no words can describe．Sometimes the best thing one can do is to listen openly and sympathetically．
The first two times we met，David didn't say a word．He sat there，only looking up to look at the children's drawings on the wall behind me．I suggested we play a game of chess．He nodded．After that he played chess with me every Wednesday afternoon-in complete silence and without looking at me．It's not easy to cheat in chess，but I admit I made sure David won once or twice．
Usually，he arrived earlier than agreed，took the chess board and pieces from the shelf and began setting them up before I even got a chance to sit down．It seemed as if he enjoyed my company．But why did he never look at me？
"Perhaps he simply needs someone to share his pain with，"I thought．"Perhaps he senses that I respect his suffering．"Some months later，when we were playing chess，he looked up at me suddenly．
"It's your turn，"he said．
After that day，David started talking．He got friends in school and joined a bicycle club．He wrote to me a few times，about his biking with some friends，and about his plan to get into university．Now he had really started to live his own life．
Maybe I gave David something．But I also learned that one-without any words-can reach out to another person．All it takes is a hug，a shoulder to cry on，a friendly touch，and an ear that listens．

47．When he first met the author，DavidC．
A．felt a little excited

13．The air quality has worsened in the Chinese capital since Wednesday，causing renewed discontent among residents．
Without rainfall and wind to decrease pollutants，particulate matter（颗粒物质） has been accumulating in the air．Most monitoring stations measured PM 10 （particulate matter smaller than 10 micrograms） at higher than 300 micrograms per cubic meter．In southwestern Beijing's Fangshan District，the Liangxiang station recorded 516 micrograms of PM 10 per cubic meter，the highest reading of the day，according to the Beijing Municipal Environmental Monitoring Center．More than 150 micrograms is considered harmful to health．

20．We know that sugary sodas aren't good for our bodies．Now it turns out that they may not be good for our minds，either．A new study of more than 260，000 people has found a link between sweetened soft-drinks and depression，and diet sodas may be making matters worse．
Americans drink far more sodas than people in other countries-as much as 170 liters per person per year．But the impact of this study isn't limited to the United States．"Sweetened drinks，coffee and tea are commonly consumed worldwide and have important physical consequences．And they may have important mental-health consequences as well，"study author Dr Honglei Chen said in a statement．
The study studied 263，925 people between the ages of 50 and 71．Researchers followed their consumption of drinks like soda，tea coffee，and other soft drinks from 1995 to 1996 and then.10 years later，asked them if they had been diagnosed with depression since the year 2000．More than 11，3000 of them had．
Participants who drank more than four servings of sodas per day were 30 percent more likely to develop depression than participants who did not drink sodas at all．People who stuck with fruit punch（鸡尾酒），had a 38 percent higher risk than people who didn't drink sweetened drinks．And all that extra sugar isn't the actual problem．Researchers say that the artificial sweetener aspartame may be to blame．
The study found a link but could not surely determine whether sodas and other sweet soft drinks cause depression．Still，the results"are consistent with a small but growing body of evidence suggesting that artificially sweetened beverages may be linked to poor health outcomes．"
But there's a bright side for those who can't live without their daily sodas．Adults who drank coffee had a 10 percent lower risk of depression compared to people who didn't drink any coffee，according to the study．"Our research suggests that cutting out or down on sweetened diet drinks or replacing them with unsweetened coffee may naturally help lower your depression risk，"said Chen．

41．What has the new study of more than 260，000 people found？C
A．Sugary sodas aren't good for the physical health of old people．
B．Americans have a special tooth for sweet foods．
C．Sweetened soft-drinks may increase the risk of depression．
D．Sweetened soft-drinks have important physical consequences．
42．What do we know about the process of the study？D
A．About twenty-six thousand people participated in it．
B．The oldest participants were below 80 when the study was over．
C．Most of the participants had depression when the study was over．
D．The study lasted more than ten years from the beginning to the end．
43．We infer that the underlined word"aspartame"in Paragraph 4 refers to something thatD
A．can reduce the harm of sweetened drinks
B．is used to reduce the risk of depression
C．is mainly used to make fruit punch
D．is used to make something．sweet
44．It is implied in the passage thatA．
A．more research is needed to confirm the new findings
B．the new findings aren't consistent with any previous findings
C．cutting one's sodas intake will surely reduce one's depression
D．the new findings won't have an impact on people's drinking habits
45．What should you drink in order to reduce the risk of depression？B
A．Sodas．
B：Unsweetened coffee．
C．Sugary coffee．
D．Fruit punch．

18．Do you want to live with a strong sense of peacefulness，happiness，goodness，and self-respect？The collection of happiness actions broadly categorized as"honor"help you create this life of good feelings．
Here's an example to show how honorable actions create happiness．
Say a store clerk fails to charge us for an item．If we keep silent，and profit from the clerk's mistake，we would drive home with a sense of sneaky excitement．Later we might tell our family or friends about our good fortune．On the other hand，if we tell the clerk about the uncharged item，the clerk would be grateful and thank us for our honesty．We would leave the store with a quiet sense of honor that we might never share with another soul．
Then，what is it to do with our sense of happiness？
In the first case，where we don't tell the clerk，a couple of things would happen．Deep down inside we would know ourselves as a type of thief．In the process，we would lose some peace of mind and self-respect．We would also demonstrate that we cannot be trusted，since we advertise our dishonor by telling our family and friends．We damage our own reputations by telling others．In contrast，bringing the error to the clerk's attention causes different things to happen．Immediately the clerk knows us to be honorable．Upon leaving the store，we feel honorable and our self-respect is increased．Whenever we take honorable action we gain the deep internal rewards of goodness and a sense of nobility．
There is a beautiful positive cycle that is created by living a life of honorable actions．Honorable thoughts lead to honorable actions．Honorable actions lead us to a happier existence．And it's easy to think and act honorably again when we're happy．While the positive cycle can be difficult to start，once it's started，it's easy to continue．Keeping on doing good deeds brings us peace of mind，which is important for our happiness．

51．According to the passage，the positive action in the example contributes to ourA．
A．self-respect
B．financial rewards
C．advertising ability
D．friendly relationship
52．The author thinks that keeping silent about the uncharged item is equal toB．
A．lying           B．stealing
C．cheating       D．advertising
53．The phrase"bringing the error to the clerk's attention"（in para.5）meansA．
A．telling the truth to the clerk
B．offering advice to the clerk
C．asking the clerk to be more attentive
D．reminding the clerk of the charged item
54．How will we feel if we let the clerk know her mistake？C
A．We'll be very excited．
B．We'll feel unfortunate．
C．We'll have a sense of honor．
D．We'll feel sorry for the clerk．
55．Which of the following can be the best title of this passage．D
A．How to Live Truthfully
B．Importance of Peacefulness
C．Ways of Gaining Self-respect
D．Happiness through Honorable Actions．
