The Threat to Kiribati
The people of Kiribati are afraid that one day in the not-too-distant future, their country will disappear from the face of the earth-literally. Several times this year, the Pacific island nation has been flooded by a sudden high tide. These tides, which swept across the island and destroyed houses, came when there was neither wind nor rain. “This never happened before," say the older citizens of Kiribati.
What is causing these mysterious high tides? The answer may well be global warming. When fuels like oil and coal are being burned, pollutants (污染物) are released; these pollutants trap heat in the earth's atmosphere. Warmer temperatures cause water to expand and also create more water by melting glaciers (冰川) and polar (级地的) ice caps.
If the trend continues, scientists say, many countries will suffer. Bangladesh, for example, might lose one-fifth of its land. The coral (珊瑚) island nations of the Pacific, like Kiribati and the Marshall Islands, however, would face an even worse fate-they would be swallowed by the sea. The loss of these coral islands would be everyone's loss. Coral formations are home to more species than any other place on earth.
The people of these nations feel frustrated. The sea, on which their economies have always been based, is suddenly threatening their existence. They don't have the money for expensive technological solutions like seawalls. And they have no control over the pollutants, which are being released mainly by activities in large industrialized countries. All they can do is to hope that industrialized countries will take steps to reduce pollution. 第5部分：补全短文 阅读下面的短文，文章中有5处空白，文章后面有6组文字，请根据文章的内容选择5组文字，将其分别放回文章原有位置，以恢复文章原貌。
Should the U.S. halt human space flight?
The Columbia accident has revived the debate on whether the rewards of
human space exploration are worth the risks
No. I was a teacher when men first landed on the moon in 1969, and I remember how it moved my students and this country. 1 And we haven't ventured outward since then. That's 30 years too long! America's human space-flight program 'is adrift, with no clear vision or goals beyond the completion of the International Space Station.
I want NASA to establish a phased series of goals over the next 20 years, including human visits to asteroids that cross the Earth's orbit, establishing a research and living facility for humans on the moon, and human expeditions to the surface of Mars and its moons. 2
An astronaut is today's Christopher Columbus, who sailed into the unknown and discovered the Americas. The knowledge we gain from having actual people exploring can never be replaced by robots. 3 Robots are useful, but humans can do things that robots can't.
The real obstacle we face in overcoming the drift in the nation's human space-flight program is not technological and it's not financial. 4
The lesson from the Columbia accident is net that humans don't belong in space. 5
A Instead, we should honor the memory of the lost astronauts by pushing our exploration of space future.50
B Astronauts are key to this expanded exploration.47
C It's the lack of commitment to get started.49
D Until then, we should stop risking people's lives by sending them into space.
E It is now more than 30 years since the last American left the surface of the moon and returned to Earth.46
F Our ability to send humans into space and have them return gives us amazing information about ourselves and our universe.48 第6部分：完形填空 阅读下面的短文，文中有15处空白，每处空白给出了4个选项，请根据短文的内容从4个选项中选择1个最佳答案。
The American Family
In the American family the husband and wife usually share important decision making. When the children are 1 enough, they take part as well. Foreigners are often surprised by the permissiveness (宽容) of American parents. The old rule that "children should be seen and not heard" is rarely 2 , and children are often allowed to do 3 they wish without strict control of their parents. The father seldom expects his children to listen to him 4 question, and children are encouraged to be 5 at an early age. Some people believe that American parents carry this freedom 6 far. Others think that a strong father image, would not 7 the American values of equality and independence. Because Americans emphasize the importance of independence, young people are expected to 8 their parental families by the time they have 9 their late teens or early twenties. Indeed, not to do so is often regarded as a 10 , a kind of weak dependence.
This pattern of independence often results in serious 11 for the aging parents of a small family. The average American is expected to live 12 the age of 70. The job-retirement age is 13 65. The children have left home, married, and 14 their own households. At least 20 percent of all people over 65 do not have enough retirement incomes. 15 the major problem of many elderly couples is not economic. They feel useless and lonely with neither an occupation nor a close family group.
