题目内容

You might think that “global warming” means nothing more than a rise in the world’s temperature. But, rising sea levels caused by it have resulted in the first evacuation (撤离) of an island nation — the citizens of Tuvalu will have to leave their homeland.

During the 20th century, sea level has risen 8～12 inches. As a result, Tuvalu has experienced lowland flooding of salt water which has polluted the country’s drinking water.

Paani Laupepa, a Tuvaluan government official, reported to the Earth Policy Institute that the nation suffered an unusually high number of fierce storms in the past ten years. Many scientists connect higher surface water temperatures resulting from global warming to greater and more damaging storms.

Laupepa expressed dissatisfaction with the United States for refusing to sign the Kyoto Protocol, an international agreement calling for industrialized nations to reduce their green house gas emissions (排放), which are a main cause of global warming.“By refusing to sign the agreement, the US has effectively taken away the freedom of future generations of Tuvaluans to live where their forefathers have lived for thousands of years,” Laupepa told the BBC.

Tuvalu has asked Australia and New Zealand to allow the gradual move of its people to both countries.

Tuvalu is not the only country that is vulnerable (易受影响的) to rising sea levels. Maumoon Gayoon, president of the Maldives, told the United Nations that global warming has made his country of 311 000 an“endangered nation”.

1.The text is mainly about___________.

A. rapid changes in earth’s temperature?

B. bad effects of global warming

C. moving of a country to a new place

D. reasons for lowland flooding

2.According to scientists, the DIRECT cause of more and fiercer storms is __________.

A. greenhouse gas emissions in industrialized nations

B. higher surface water temperatures of the sea

C. continuous global warming

D. rising sea levels

3.Laupepa was not satisfied with the United States because it did not _________.

A. agree to reduce its greenhouse gas emissions

B. sign an agreement with Tuvalu

C. allow Tuvaluans to move to the US

D. believe the problems facing Tuvalu were real

4.The country whose situation is similar to that of Tuvalu is _________.

A. Australia B. New Zealand

C. the Maldives D. the United States

A fish may not be the first creature that comes to mind when co-operation in the animal world is mentioned, but a new study has shown the caring behavior of one sea species. Scientists have found that pairs of rabbitfishes will help and support each other while feeding. While such behavior has been recorded for birds and mammals, it had formerly been thought to be impossible for fishes to exhibit the same features.

＂We found that rabbitfish pairs manage their caring activity quite firmly, thus providing safety for their partner that is looking for food,＂ says Dr. Simon Brandl. ＂In other words, one partner stays ‘on guard’ while the other feeds – these fishes just watch each others’ back,＂ Dr. Brandl says. ＂This behavior is so far unique among fishes and appears to be based on reciprocal cooperation between pair members.＂

Reciprocal cooperation, which requires an investment in a partner that is later reciprocated（报答）, is supposed to require complex cognitive and social skills — something that fishes had been considered not to have until now.

Dr. Brandl says the research shows clear support and presents interesting evidence for reciprocal support between the rabbitfish pairs.

＂There has been a long debate about whether reciprocal cooperation can exist in animals that lack the highly developed cognitive and social skills found in humans and a few species of birds and primates,＂ he said. ＂By showing that fishes — which are commonly considered to be cold, unsocial, and unintelligent — are able to have reciprocal cooperative systems, we provide evidence that cooperation may not be as special as earlier expected.＂

Professor Bellwood says that our opinion of fishes as cold creatures is slowly changing. ＂Our findings should further cause efforts to understand fishes as highly developed organisms with complex social behaviors. This may also require a change in how we study and treat fishes.＂

【题文1】 What does the first paragraph imply?

A. Rabbitfishes almost act like birds and mammals.

B. Fishes don’t belong to the animal world at all.

C. Fishes have the ability to feed each other.

D. The caring behavior is impossible for fishes.

【题文2】While one rabbitfish feeds, the other one _________.

A. is protecting its partner from any danger B. is carrying some food for its partner

C. is looking for more food for its partner D. is hiding behind the back of its partner

【题文3】 What did people use to think about fishes?

A. They have the same behaviors. B. They show no feelings for others.

C. They have high social skills. D. They support each other all the time.

【题文4】What can we infer from what Bellwood said？

A. We should change our way of eating fish.

B. The behaviors of fishes are difficult to learn.

C. More efforts are needed to understand fish.

D. Our study of social behaviors should be careful.

I think the majority of people would agree that it’s unhealthy to live in the past. After all, we’re all familiar with the new age philosophy, “Yesterday is history, tomorrow is a mystery, but today is a gift.1.. Living in the past holds us back from being able to enjoy the present moment. But are there any benefits of revisiting a previous time? Actually, yes. The past has several advantages:

Learning from our mistakes: We all know that poor choices can be some of life’s greatest teachers.2..

3.: By revisiting an unfavorable event from our past, we can often view it from a different perspective as time has passed. Being older and wiser, we are now able to reevaluate the experience and gain deeper insights and understandings of what happened and why, and how it has impacted us since. What once scarred us can now be healed through a newly-found awareness and no longer be a negative force in our lives.

Motivated by earlier successes:4.. Other times life has been difficult. Remembering the past when we were at our best can help motivate us out of our current slump(低谷) and put us back on track for success. Use your past successes to propel(推动) you on to newer and greater things.

While it’s evident that revisiting the past has several advantages, there is a warning. Just like an amusement park, it’s fine to visit but you cannot stay there forever. At some point, the park closes and all visitors are asked to leave. Enjoy the past when necessary but don’t always stay there. Use it for living in the present and planning for the future.5..

A. Moving beyond

B. That’s why it’s called the present

C. In that way, it will serve you well

D. See the mistakes as a step on the road to a solution

E. There are times when we have all enjoyed success on a variety of levels

F. Recalling times when we made mistakes can help us make better future decisions

G. So, failure is the mother of success

The summer holiday is coming. My classmates and I are talking about how to do during the holiday. We can chose between staying at home and take a trip. If we stay at home, it is comfortable but there is no need to spend money. But in that case, we will learn little about world. If we go on a trip abroad, we can broaden your view and gain knowledges we cannot get from books. Some classmates suggest we can go to places of interest nearby. I thought that it is a good idea. It does not cost many, yet we can still learn a lot.
