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.

For thousands of years, Polynesian people lived in the remote island of Nauru, far from western civilization．The first European to arrive was John Fearn in 1798．He was the British captain of the Hunter, a whaling ship．He called the island Pleasant Island．
However, because it was very remote, Nauru had little communication with Europeans at first．The whaling ships and other traders began to visit, bringing guns and alcohol．These elements destroyed the social balance of the twelve family groups on the island．A ten-year civil war started, which reduced the population from 1,400 to 900．
Nauru’s real troubles began in 1899 when a British mining company discovered phosphate (磷酸盐)on the island．In fact, it found that the island of Nauru was nearly all phosphate, which was a very important fertilizer for farming．The company began mining the phosphate．
A phosphate mine is not a hole in the ground; it is a strip mine．When a company strip-mines, it removes the top layer of soil．Then it takes away the material it wants．Strip mining totally destroys the land．Gradually, the lovely island of Nauru started to look like the moon．
In 1968, Nauru became one of the richest countries in the world．Every year the government received millions and millions of dollars for its phosphate．
Unfortunately, the leaders invested the money unwisely and lost millions of dollars．In addition, they used millions more dollars for personal expenses．Soon people realized that they had a terrible problem — their phosphate was running out．Ninety percent of their island was destroyed and they had nothing．By 2000, Nauru was financially ruined．Experts say that it would take approximately $433,600,000 and more than 20 years to repair the island．This will probably never happen．
小题1:What might be the author’s purpose in writing the text?
| A．To seek help for Nauru’s problems． |
| B．To tell a heartbreaking story of a war． |
| C．To show the importance of money |
| D．To give a warning to other countries |
| A．Rich and powerful | B．Peaceful and attractive |
| C．Modern and open | D．Greedy and aggressive |
A．phosphate overmining B soil pollution
C．farming activity D．whale hunting
小题4:Which of the following was a cause of Nauru’s financial problem?
| A．Its phosphate mining cost much money |
| B．It spent too much repairing the island |
| C．Its leaders misused the money |
| D．It lost millions of dollars in the civil war． |
| A．The ecological damage is difficult to repair． |
| B．The leaders will take the experts’ words seriously． |
| C．The island was abandoned by the Nauruans |
| D．The phosphate mines were destroyed |
The setting: Urban England (the cities), but also rural England (the countryside) including remote English villages．
The theme: The main theme is a teenage research of self-discovery, in this case the search for a mother from whom the hero was separated at an early age．Its other concerns are love, getting on with others, being persistent and courageous and trying to deal with doubts, troubles and worries．As the book moves to a close, James’ swimming coach says to him: “You are not like a kid obeying instructions any more．You are diving like a young man who knows where he is going．”
The characters: James is the hero of the story．He is a championship diver, and has a comfortable life with his foster parents (养父母)．Yet he also has the qualities to take him on a long journey to find his birth mother．The other characters in The Snake-Stone, James’ parents, his diving instructor, best friend, the villagers, people he meets on his journey, are pictured realistically．
The turning point: The turning point in the story comes while James’ foster parents are away in London, and he wonders about the identity of his birth mother．The only clue he has is a fossil, “the snake stone” which she left behind along with a note on which she had written: “Take good care of Sammie．It was written on a torn envelope with parts of an address still there．
The journey: Instead of going to London, James decides to find his birth mother．With help from his geography teacher, James sets out for the remote country village where his mother might be found．James has painful, challenging, but also humorous and happy travels．The mother he finally meets, Anne, has a minor yet powerful voice in the novel．He comes to understand why she left him at a stranger’s door fifteen years before．Although the meeting is not long, it leaves him with a feeling of completeness．As a journey of self-discovery The Snake-Stone also provides its readers with a happy ending．Its hero says, on returning to his foster parents, “I was home．”
