问题补充：
What do you think the future will be like? Here are some answers from some students.
Mary: If we don’t take good care of the earth now, our children and grandchildren will be born into a world with much pollution(污染). There will be fewer trees and more buildings, because there will be more people.
Jack: I agree with Mary. Things will be worse(更糟). The weather in the future will be much hotter. Humans(人类)won’t be able to live on the earth. They will have to look for another planet to live on.
Linda: I think the life in the future will be better. Most people in the world will use “green cars” by , so there will be less pollution and people will live to be 200 years old. As for(至于)space travel, I would say, we will visit Mars(火星)in about fifty years.

答案：
(答案→)C
解析：这篇短文讲的是人们对未来世界是什么样子的一些预测。在短文中三位同学发表了自己的观点。Mary认为将来地球上的树会更少，楼会更多，因为将来人会更多；Jack认为未来地球会变得太热而不能居住；Linda认为未来人们的生活会变得更好。
【小题1】主旨大意题。根据短文的开头What do you think the future will be like? Here are some answers from some students可知，你认为将来是什么样子的？这里是来自于一些学生的答案。这是这篇短文的中心句，下面给我们列举了三个学生对这件事情的看法。所以这篇短文主要讨论的是将来的生活。故选C。
【小题2】细节理解题。根据短文的第二段Mary所说的话中There will be fewer trees and more buildings, because there will be more people可知，Mary认为将来将会有更少的树和更多的大楼，因为将来会有更多的人。故选A。
【小题3】词义猜测题。根据这个单词所在的句子Humans(人类)won’t be able to live on the earth. They will have to look for another planet to live on. 可知，Jack觉得未来人类将不能住在地球上，他们将会寻找另一个星球来居住。这里的planet 是指像地球一样的其他星球，而不是沙漠、岛屿或海底，这些都不是人类能居住的地方。故选C。
【小题4】推理判断题。根据短文中Jack的观点The weather in the future will be much hotter.可知，Jack认为未来天气将会变得很热，所以人类将不会在地球上居住，而是要寻找其他的星球。故选B，地球将会变得太热了而不能居住。
【小题5】细节理解题。根据短文的最后一点Linda的观点中可知，Linda预测Most people in the world will use “green cars” by ，到世界上的人们将会使用绿色汽车；there will be less pollution，污染将会更少；people will live to be 200 years old，人们将会活到200岁；we will visit Mars in about fifty years，大约50年后我们将能够去火星。故一共是四件事情。故选D。
