The cutting of forests reduced the supply of oxygen. The killing of weeds and insects by chemicals led to the wide-spread poisoning of animals and birds. The throwing of waste products into the ocean hurt life in the sea, while waste gases changed the chemical balance of the atmosphere and shut out some of the sun’s necessary life-giving rays.
And so we could go on adding more examples until in despair(绝望) we might feel like giving up the struggle to control these harmful human activities. Man is very clever at changing the world around him to satisfy his immediate needs, but he is not so clever at looking far ahead, or at thinking about what the future results of his action might be. Man may well destroy himself because of his silly action.
小题1:The first paragraph tells us that _____.
| A．all living things in nature depend on each other |
| B．everything in nature can’t exist without the help of man |
| C．man has known the importance of the balance of nature for a long time |
| D．no living thing can live naturally |
| A．all forms of life belong to a system in which all the parts can be changed for one another |
| B．it is only during the last few years that man has generally known the balance of nature |
| C．there are some living things which can exist by themselves without change |
| D．we can’t change one form of life without destroying the balance of nature |
| A．man is always anxious to control his activities within limits |
| B．man is always too eager in planning for distant future |
| C．man often fails to think about their future results of his action |
| D．man often feels that he will have to give up in despair |
| A．Cutting down woods does little harm to human beings. |
| B．Man has to pay much more attention to the future results of his present action. |
| C．Oxygen comes from forests. |
| D．The passage tells us to try our best to get as much as possible immediately. |

The Eskimo year has two main parts: a long, cold winter and a short, cool summer. Spring and fall are almost too short to be noticed. Summer is the best time, as food is usually plentiful. But it is also the time when Eskimos are very busy. Winter is never far away, and the men must bring home extra meat for the women to prepare and store, for seldom can enough animals be killed in winter to feed a family.
The Far North is sometimes called the land of the midnight sun. This is true in the middle of summer, for between April 21st and August 21st the sun never sets in Northern Greenland. But in midwinter the Far North is a land with no sunshine at all. Around Oct. 21st the Eskimos of Northern Greenland see the sun set directly south of them, and they don’t see it again until February 22nd. All places on earth get about the same amount of daylight during a year. As a result, if summer is lighter, winter has to be darker.
Winter nights in the Far North are seldom pitch-black. As in the rest of the world, the stars and moon provide a little light. The northern lights also help the Eskimo to see. And with the ground covered with snow, even a little light is reflected back to the Eskimo’s eyes.
小题1:Which of the following statements is NOT true?
| A．Eskimos do not usually eat wolves. |
| B．Eskimos like to chase one another. |
| C．Eskimos depend heavily on water. |
| D．Eskimos are meat-eaters. |
| A．Dark with a little light. |
| B．A little dark. |
| C．Not dark at all. |
| D．Extremely dark. |
| A．Eskimos are more likely to eat wolves in summer |
| B．Eskimo women are responsible for housework |
| C．meat is the main source of food for the Eskimo |
| D．hunting is an important part of Eskimo life |
Burning biomass is one way to capture its energy, but Brown hopes panda poop can teach scientists something about breaking down biomass. Pandas—or at least the bacteria in their stomachs—are very good at getting energy out of bamboo. Unlike cows, which use 4 stomachs to digest large amounts of grass, a panda has only one stomach. Bamboo comes in, and poop goes out.
Every day for 14 months, Brown and her team on this project, counted the bacteria in the poop of the two pandas, YaYa and LeLe living at the Memphis Zoo. Her studies turned up 12 species of bacteria that break down biomass, including one that had never been found in pandas. Brown says that because the poop contains bacteria that break down biomass, it could also be used to break down other types of biomass.
Now the scientists hope to identify the chemicals that help with the process of breaking down biomass and then figure out how the bacteria work. If those chemicals can be made in the lab, they could be used to turn biomass—like grass or other plants—into fuel.
Brown says she doesn’t mind handling panda poop. “It’s probably the most pleasant material to work with,” she says, “My colleagues and I have been working with other poop for a long time, and we can assure you it has a fairly pleasant smell associated with it.”
小题1:The importance of studying panda poop is _______.
| A．to create a renewable energy from plants |
| B．to explore a new way to get energy from plants |
| C．to learn a lesson of energy from panda poop |
| D．to figure out how the bacteria work for us mankind |
| a. Identify the chemicals helpful to break down biomass. b. Find the bacteria in panda poop which break down bamboo. c. Reproduce the chemicals in the lab to turn biomass into energy. d. Analyze how the bacteria in panda poop work in panda’s stomach. |
小题3:What does the author mainly want to express in the 2nd paragraph?
| A．Pandas don’t digest bamboo the same way as cows. |
| B．Pandas are capable of getting energy using stomachs. |
| C．Pandas can get energy from bamboo more efficiently. |
| D．Scientists have learnt something new from panda poop. |
| A．Sick | B．Challenging | C．Inspiring | D．Enjoyable |
Research shows that if high schools provide career-related courses，students are likely to get higher earnings in later years．The students are more likely to stay in school，graduate and go on to higher education．
In Germany，students as young as 13 and 14 are expected to do internships．German companies work with schools to make sure that young people get the education they need for future employment．
But in America, education reform programs focus on how well students do in exams instead of bringing them into contact with the working world．Harvard Education school professor Robert Schwartz has criticized education reformers for trying to place all graduates directly on the four-year college track．Schwartz argued that this approach leaves the country’s most vulnerable(易受影响的)kids with no jobs and no skills．
Schwartz believed that the best career programs encourage kids to go for higher education while also teaching them valuable practical skills at high school．James Madison High School in New York，for example，encourages students to choose classes on career—based courses．The school then helps them gain on—the-job experience in those fields while they’re still at high school．
However，even for teens whose schools encourage them to connect with work，the job market is daunting．In the US，unemployment rates for 16-to 19-year-olds are above 20 percent for the third summer in a row．
“The risk is that if teenagers miss out on the Summer job experience，they become part of this generation of teens who had trouble in landing a job，”said Michael，a researcher in the US.
小题1:In the author’s opinion, American high school leavers__________.
| A．have enough career-related courses |
| B．need more career advice from their schools |
| C．perform better in exams than German students |
| D．can get higher earnings in later years |
| A．there is no need for kids to go for higher education in the US |
| B．students should get contact with the working world at high school |
| C．education reform should focus on students’ performance in exams |
| D．teenagers in the US can’t miss out on the summer job experience |
| A．Unemployment rates for US teenagers remain high at the moment. |
| B．Students with career—based courses never have problems finding a job. |
| C．US companies work with schools to prepare young people for future employment. |
| D．High school leavers with no practical skills can’t find a job absolutely |
| A．Arguments about recent US education reform. |
| B．Tips on finding jobs for high school leavers. |
| C．The lack of career—based courses in US high schools. |
| D．Advice for American high school leavers. |
| A．discouraging | B．interesting |
| C．creative | D．unbearable |
Making connections. This technique involves taking 15 ideas and trying to find links between them. First, think about the problem you have to solve or the job you need to do. Then find an image, word, idea or object, for example, a candle. Write down all the ideas/words 16 with candles: light, fire, matches, wax, night, silence, etc. Think of as many as you can. The next stage is to relate the 17 to the job you have to do. So imagine you want to buy a friend an original 18 ; you could buy him tickets to match or take him out for the night.
NO limits! Imagine that normal limitations don’t 19 . You have as much time /space / money, etc. as you want. Think about your goal and the new 20 . If your goal is to learn to ski, 21 , you can now practise skiing every day of your life (because you have the time and the money). Now 22 this to reality. Maybe you can practise skiing every day in December, or every Monday in January.
Be someone else! Look at the situation from a 23 point of view. Good businessmen use this technique in trade, and so do writers. Fiction writers often imagine they are the 24 in their books. They ask questions: What does this character want? Why can’t she get it? What changes must she make to get what she wants? If your goal involves other people, put yourself in their 25 . The best fishermen think like fish!

Migrating or mobile animals move through several environments as they travel away from the cold of winter to warmer areas. Birds may fly from one part of the world to another, perhaps stopping at feeding grounds on the way. Whales and turtles (海龟) cover vast areas of ocean. The report says that changes in any one of the places which these animals use can cause serious harm. "Obviously these animals have developed their travelling patterns over thousands of years. But climate change is almost certain to be extreme over the next 25 to 50 years and it is extremely unlikely that these animals can change their habits fast enough," said the report author Dr Robert Hepworth.
Hardest hit by rising temperatures are turtles. Scientists have found that at higher temperatures, turtles produce far more female eggs than male ones. In parts of Malaysia, turtle birthing sites are producing only females, the report says. It also provides evidence that some turtles are more likely to develop cancer as the waters get warmer.
With birds, the main problem is climate-related damage to important areas at either end of the travels or at resting places along the way. About one-fifth of migrating birds are now in danger because of climate-related changes including rising sea levels, land loss and more violent storms, the report concludes.
Other animals picked out as particularly in danger include:
· the North Atlantic Right Whale, whose main food (tiny shrimp) is disturbed by the change in ocean flows and
· the White-Nose Dolphin, which is out-competed by other kinds of dolphins in warmer waters.
The report is not all bad news. Even with major climatic changes, protecting the environment can still help mobile animals to recover. "We need governments to start taking action at the national and international lever. “The clock is running.” said Dr Hepworth. And some animals are already adapting, with the report mentioning whales that are changing their feeding behaviour, finding new feeding grounds and new foods to eat.

| A．The effect of climate change on migrating animals. |
| B．How animals are adapting to changes in temperature. |
| C．The actions required to save migrating animals. |
| D．The need for government policies to prevent global warming. |

| D．it takes time to complete the actions |
| A．They will only produce female babies. |
| B．Their food supply will gradually disappear. |
| C．Some will suffer from higher rates of cancer. |
| D．They will be in greater danger because of more violent storms. |
| A．More storms will affect the ability of whales to find their feeding grounds. |
| B．20 percent of all birds are likely to die out because of land loss. |
| C．Migrating animals are likely to start adapting to the changes more quickly. |
| D．Warmer oceans will increase the competition between different kinds of dolphins. |
| A．They are the only animals besides humans that suffer from cancer. |
| B．They have traditionally lived longer than other ocean-based animals. |
| C．Those born nearer a hotter area are more likely to be female. |
| D．Most kinds of turtles are likely to die out within 50 years. |
