A
Some people are pessimistic(悲观的) when they think about the future. They say that, a hundred years from now, we will have used most of the earth's resources. We will have polluted our seas badly, and be unable to eat fish from them. We will have made the air so dirty that we will need to wear masks. The world's population will have doubled, and we will have used all the countryside for housing; there will be no farmland left.
Other people believe that man adapts very easily. They have a different idea of the future. How, in their views, will people be living in a hundred years' time?
One architect(建筑师) believes that man will move off the land. He suggests that the city of the future will be a huge, pyramid－shaped(金字塔形的) building, which will be floating on the surface of the sea. About 5,000 families will be living there, and the building will contain shops and schools as well as homes. By living on the sea, we will give farmers more land to grow crops.
As for oil, people will no longer need it: we will be heating our homes with power from the sun. And we will not be short of minerals, because there are plenty under our oceans. At the moment, we do not have the technology to get them out. But, in a hundred years' time, the optimists say, the new sea cities will be using these resources.
What will be in the shops in the year 3000? What will people be wearing? How will people be traveling?
Scientists who make predictions about the future suggest that, by the year 3000, shops will no longer exist. Computers will have replaced them; and people will order goods from home.
People will be wearing very light, thin clothes. By this time, scientists will have invented a fabric(织物) that keeps us cool in hot weather and warm in cold weather.
As for travel, the experts say that most people will be using public transport. Electric cars will be traveling through the streets day and night. Anybody will be able to stop one and use it.
An interesting picture. Unfortunately, we will not be there to see if these predictions come true.
语篇解读：本文主要介绍了人们对未来生活的不同看法以及人们对未来生活的预测。
1．Pessimists believe that in the future ________.
A．the seas and oceans will be full of houses
B．we'll have used up all the resources
C．we will not have enough fish to eat from the seas
D．we will have polluted the air so badly that it will be impossible for us to breathe
[解析] 细节理解题。由文章第一段的第四句“We will have made...to wear masks.”可知，悲观的人认为一百年之后，因为空气受到严重污染，人们必须要戴着面具，故D项正确。A项是一位建筑师的假想，不符合题干要求；B项应为大部分资源被用完而非全部；C项应为海水因受到污染导致鱼不能食用，故排除。
[答案] D
2．Optimists suggest that in the future ________.
A．all the land will be too polluted to be cropped on
B．pyramids will be most commonly－used houses
C．people will be using the power from the sun instead of oil
D．we will be short of materials even though we get them from under the oceans
[解析] 细节理解题。由文章第四段第一句可知，人们将不再使用石油，而是利用太阳能来取暖。其他选项与原文不符。
[答案] C
3．Scientists have made the predictions EXCEPT ________.
A．electric cars will be going along the streets continuously
B．the resources under the oceans will never be used up
C．people will order goods from home
D．people won't suffer from cold any longer
[解析] 细节理解题。文章最后四段是科学家的推测。倒数第二段第二句提到日夜运作的电车；倒数第四段末句提到人们将在家中订购物品；倒数第三段末句提到新发明的织物会使我们觉得冬暖夏凉；只有B项文中未提及。
[答案] B
