Indonesia is known as the country of islands. It has 17,508 islands. But in recent years, the popular tourist destination has lost some of its shine.
Due to rising sea levels caused by global warming, 24 Indonesian islands have gone under the sea. Scientists say 2,000 more will disappear before 2030. In the past three years, the Southeast Asian nation also witnessed its islands destroyed by a tsunami(海啸) and typhoons.
“If no measures are taken to fight climate change, the beautiful islands will go forever,” scientists told environmental ministers from about 190 countries at a UN climate change meeting.
This week they are meeting in Bali, an Indonesian island. They are trying to reach a deal to cut the world’s emissions (排放) of CO2 , which makes the Earth warmer.
Indonesia is not alone. This year has seen more extreme weather hit the world. Canada and US suffered heavy storms and typhoons, while Australians were caught in the heaviest drought in a century.
In China, the average temperature this year went up by 1.2oC from last year, reaching the highest on record since 1951.
However, other parts of the country got too much rain. More than 700 people were killed in floods, landslides and storms. “These weather extremes are the more obvious effects of global warming,” said Song Lianchun, a climate expert.
Scientists say time is running out. To escape from the worst effects, global CO2 emissions need to be cut from the levels they were at in 2000 by 50 to 85 percent by 2050.
But in recent years climate change talks have been bogged down by arguments over who will pay the bill for cleaner technology. Developing countries are worried that the cut in emissions will slow their economic development.
“China will play a responsible and constructive rule in the meeting,” said Chinese Premier Wen Jiabao. The nation is now the world’s second largest greenhouse gas emitter(排放者). “However, developed nations should help developing nations deal with the global issue.”

C. The disappearance of more and more farmland.
D. Different amount of rain in different areas.
55. Climate change talks have been stopped because countries cannot agree on ______.
A. who should be responsible for causing climate change
B. who will pay for the cleaner technology needed

B. China will take an active part in dealing with climate change.
C. China thinks it is developed countries’ responsibility.
D. China will depend on developed countries to help it.

If your head is overheating, you are very likely to yawn(打哈欠) soon, according to a new study that has found the main purpose of yawning is to control brain temperature. The study explains several mysteries about yawning, such as why it’s most commonly done just before and after sleeping, why certain diseases lead to too much yawning, and why breathing though the nose often stops yawning.
“Brains are like computers,” Andrew Gallup, a researcher in the department of Biology at Binghamton University who led the study, said. “They operate best when cool.”
He and his co-workers Micheal Miller and Anne Clark did researches on yawning in parakeets(长尾小鹦鹉) , which have relatively large brains, live wild in Australia, often experience temperature changes, and, most importantly, do not yawn when others yawn, as humans and some other animals do.
For the study, the scientists put parakeets under three different conditions: increasing temperature, high temperature and normal temperature. While the frequency(频率) of yawns did not increase under the latter two conditions, it increased greatly when the researchers increased the temperature.
It’s now believed yawning operates like a radiator(散热器).
If air in the atmosphere is cooler than the brain and body temperatures, taking it in quickly cools blood, which in turn cools the brain. The new findings also explain why tired people often yawn. Both tiredness and sleep loss can increase brain temperature, while yawning can cool down the brain.
In the future, researchers may focus more on brain temperature and its role in diseases and their symptoms. But the new study on yawning changes the popular idea that yawns are just signs of getting tired of something.
49. What’s the best title for the passage?
A. Why don’t people yawn at normal temperature?
B. The yawn explained—it cools your brain.
C. Yawning operates like a radiator.
D. The cause of yawning—finally found out.
50. The main reason why researchers chose parakeets to do the research is that parakeets______.
A. have very large brains
B. live wild in Australia
C. are not affected by others’ yawning
D. experience frequent temperature changes
51. The writer may suggest doing all of the following to stop yawning EXCEPT______.
A. breathing through the nose
B. turning up the heat
C. enjoying some cool wind
D. putting a cold towel on your forehead
52. In which section of a newspaper would you most probably read this passage?
A. Discovery. B. Education. C. Health. D. Mystery.

In order to protect valuable energy, snails(蜗牛) basically play a game of follow-the-leader, a new study finds. Snails create trails of mucus(黏液) to help them move smoothly across the ground, mainly in search of food or a partner, but making all that mucus uses up a lot of energy.
“Snails use a lot of energy, probably a third, creating mucus,” said Mark Davies of the University of Sunderland, lead author of the study published in the journal Proceedings of the Royal Society. “This process is very tiring indeed— much more so than walking, swimming or flying.”
Davies and his workmates studied marine snails off the coast of Britain and discovered that to save some of this important energy, the snails sometimes follow the existing mucus trails laid down by other snails to get around and so only have to create a small part of the mucus needed to make a new trail.
“The fact that they can make savings has an effect on as much as they have to save more energy to do other things like reproducing,” Davies said.
The energy saving may also help snails which live in environments where food is not enough, making the energy harder to replace.
Biologists had long guessed that snails behaved this way, but this is the first study to directly observe it. Davies said that it is likely that all snails use this means of cutting energy as they work hard through life.
45. What’s the function of mucus that snails create?
A. To find their food B. To find their way back
C. To save their energy D. To help them move smoothly
46. According to the passage, which of the following statements is TRUE?
A. The snail’s life is very hard.
B. The snails don’t need much to reproduce.
C. This is the first time to do the guess.
D. The snails will replace more energy in places lacking food.
47. From the passage we know that ______.
A. snails’ trails are sometimes reused
B. snails’ food is difficult to find
C. snails can live a long life
D. only marine snails have the ability
48. What does the passage mainly talk about?
A. How snails move and work.

We are not born doubting ourselves. We learn to do it. In fact, we are usually taught to doubt ourselves. We can learn some ways that allow us to become more accepting of ourselves. Following are two behaviors that might explain the reasons why you can’t move towards greater self-acceptance.
One thing that might cause you not to accept yourself is over-generalizing about something you've done that you don’t like．For example, if you fail a test you might generalize and say, “I’m really a stupid person.” When you do this you are making a statement about all of you all of the time and not just about this one situation at this time. Instead, you might decide that your grade on this test in this subject at this time was indeed poor, and then go on to decide what you want to do about your poor grade, if anything. Getting stuck in over-generalizing discourages you from taking steps that might allow you to do better on the next exam and to build an expectation of future failure.
Having standards that are impossibly high is a second way you can not accept yourself. It may not come as a surprise to you that most of us are more demanding of ourselves than we are of others. Somehow we can tolerate the fact that other people fail, that they aren’t always kind, that they’ve done things they aren’t proud of, but we have difficulty accepting those very human aspects of ourselves. The need to be perfect is another way to set yourself up for failure and enhance the feeling that you are not acceptable. We all make mistakes. Accepting less than perfection simply means recognizing the limitations natural in being born a human being. Learn to value who you are rather than who you could become. Wouldn’t it be overpowering if we always had to do what we imagine we could do? Nobody has the time and energy to do all of that. We must make choices about what we will pursue and do them the best we can under the circumstances, which aren’t always ideal, by the way.
60．Which of the following is true according to the passage?
A. We can feel that we are perfect when we set ourselves up for success.
B. We can tolerate the fact that we’ve done things we aren’t proud of.
C. Over-generalizing might encourage you to expect the future.
D. Over-generalizing might cause you not to accept yourself.
61．What is the author’s attitude according to the passage?
A. It’s necessary for people to be perfect.
B. It’s acceptable for people to be imperfect.
C. It’s strange for people to be born with limitation.
D. It’s possible for people to do what they imagine.
62．What has caused the lack of self-acceptance?
A. Tolerance and high-level.
B. Limitation and expectation.
C. Over-generalization and high-standard.
D. Extreme difficulty and complete failure.
