When the world was a simpler place ,the rich were fat ,the poor were thin ,and right-thinking people worried about how to feed the hungry .Now ,in much of the world ,the rich are thin ,the poor are fat ,and right-thinking people are worrying about fatness.?
Evolution（进化）is mostly to blame. It has designed mankind to deal with lack ,not plenty .People are perfectly fit to store energy in good years to see them through lean ones. But when bad time never comes ,they are stuck with that energy ,stored around their expanding bellies.?
Thanks to rising agricultural productivity ,lean years are rarer all over the globe .According to the UN ,the number of people short of food fell from 920 m in 1980 to 799 m 20 years later ,even though the world's population increased by 1.6 billion over the period .This is mostly a cause for celebration .Mankind has won what was ,for most of his time on this planet ,his biggest battle：to ensure that he and his offspring had enough to eat. But every silver lining has a cloud ,and the result of prosperity is a new trouble.?
Fatness is the world's biggest public-health topic today—the main cause of heart disease ,which kills more ?people? these days than AIDS ,malaria（疟疾）,war; the major risk factor in diabetes（糖尿病）；heavily connected with cancer and other diseases .Since the World Health Organization labeled fatness an “epidemic（流行病）”in 2000,?reports? on its fearful results have come thick and fast.?
Will public-health warnings ,combined with media pressure ,persuade people to get thinner ,just as they ?finally? put them off tobacco? Possibly .In the rich world ,sales of healthier foods are booming and new figures suggest that over the past year Americans got very slightly thinner for the first time in recorded history .But even if Americans are losing a few ounces ,it will be many years before the country solves the health problems caused by half a century's dining to overload .And ,everywhere else in the world ,people are still piling on the pounds .That's why there is now an agreement among doctors that governments should do something to stop them.?

（2011·江西卷）D

Why should mankind explore space? Why should money, time and effort be spent exploring and researching something with so few apparent benefits? Why should resources be spent on space rather than on conditions and people on Earth? These are questions that, understandably, are very often asked.

     Perhaps the best answer lies in our genetic makeup(基因构成) as human beings. What drove our ancestors to move from the trees into the plains, and on into all possible areas and environments? The wider the spread of a species, the better its chance of survival. Perhaps the best reason for exploring space is this genetic tendency to expand wherever possible.

Nearly every successful civilization has explored, because by doing so, any dangers in surrounding areas can be identified and prepared for. Without knowledge, we may be completely destroyed by the danger. With knowledge, we can lessen its effects.

    Exploration also allows minerals and other potential (潜在的) resources to be found. Even if we have no immediate need of them, they will perhaps be useful later. Resources may be more than physical possessions. Knowledge or techniques have been acquired through exploration. The techniques may have medical applications which can improve the length or quality of our lives. We have already benefited from other spin-offs including improvements in earthquake prediction, in satellites for weather forecasting and in communications systems. Even non-stick pans and mirrored sunglasses are by-products (副产品)  of technological developments in the space, the chance to save ourselves might not exist.

While many resources are spent on what seems a small return, the exploration of space allows creative, brave and intelligent members of our species to focus on what may serve to save us. While space may hold many wonders and explanations of how the universe was formed or how it works, it also holds dangers. The danger exists, but knowledge can help human being to survive. Without the ability to reach out across space, the chance to save ourselves might not exist.

While Earth is the only planet known to support life, surely the adaptive ability of humans would allow us to live on other planets. It is true that the lifestyle would be different, but human life and cultures have adapted in the past and surely could in the future.

       A. To express his doubts.

       B. To compare different ideas.

       C. To introduce points for discussion.

       D. To describe the conditions on Earth.

       A. Humans are nature-born to do so.

       B. Humans have the tendency to fight.

       C. Humans may find new sources of food.

       D. Humans don’t like to stay in the same place.

73. The underlined word“spin-offs” in Paragraph 4 probably refers to______.

       A. survival chances                                          B. potential resources

       C. unexpected benefits                               D. physical possessions

74. What makes it possible for humans to live on other planets?

       A. O       ur genetic makeup.                             B. Resources on the earth..

       C. The adaptive ability of humans.              D. By-products in space exploration.

75. Which of the statements can best sum un the passage?

       A. Space exploration has created many wonders.

       B. Space exploration provided the best value for money.

       C. Space exploration may help us avoid potential problems on Earth.

请认真阅读下列短文，并根据所读内容在文章后表格中的空格里填入最恰当的单词。注意：每空格1个单词。

Ban Ki-moon was made the 8^th Secretary-General of the United Nations. In his speech at the ceremony of his taking office, he thanked all the Member States for placing confidence in him, and also expressed his deepest respect and appreciation to all the leaders and people of the Member States for their strong support.

His remark about the former Secretary-General, who he said had guided their Organization into the 21^st century and had made the UN truly vital to peace, prosperity and human dignity around the world, was particularly impressive. Mr Ban Ki-moon stated in his speech that he had already made up his mind to build upon the already-made achievements of the UN.

The new Secretary-General thinks the UN is needed now more than ever before. The UN’s major task in the previous century was to keep countries from fighting each other. In the new century, it is very clear that the UN’s most important task is to strengthen the inter-state system so that humanity may be better served. We need competent and responsible states to meet the needs of “we the peoples” for whom the UN was created. And the world’s peoples will not be fully served unless peace, development and human rights, the three pillars of the UN, are advanced together with great efforts and equal determination.

As the new Secretary-General, he is not as proud as people thought he might be. He said he was far from perfect and he would need the support, cooperation and trust from all the Member States. And he faithfully promised to serve them well, with all of his heart and to the best of his abilities.

There is also something exciting he said about young people. It’s his hope that young boys and girls of today will grow up knowing that the UN is working hard to build a better future for them. As Secretary-General, he will hold their hopes and hear their demands.

Main aspects in Ban Ki-moon’s speech
Expressing his (1) ______________	·to the Member States for feeling (2)___________ of him and being supportive ·to the former Secretary-General for the (3) ___________ he has made to the UN
