Answer 1

分析 这篇短文主要讲述环保问题．在过去，人们不必担心对环境的保护，因为那时地球上人口稀少，自然资源似乎是无限的．今天不同了，世界已变得过于拥挤．我们正在以很快的速度消耗我们的自然资源，我们也用工厂废弃物（特别是危化品）污染我们的环境．如果我们继续这样做，人类将无法生存，总之，保护我们的环境是很重要的．

解答 106．polluting；die．细节理解题．考查我们面临的资源问题和环境问题及人类的危机．根据文章第二段"We are using up our natural resources too quickly，and at the same time we are polluting our environment with dangerous chemicals．If we continue like this，human life on earth will not survive"可知，我们过快地消耗自然资源，同时用危化品污染环境．如果继续这样下去，人类将不复存在．go on polluting our environment继续污染环境．die out（指物种、家族、习惯、观念等） 绝迹，消失； 绝种； 绝灭； 淘汰．故填polluting；die．
107．take；none．细节理解题．考查过度捕捞的危害．根据地三段"Everyone realizes today that if too many fish are taken from the sea，there will soon be none left：可知，众所周知，如果人类从海洋中捕捞过多鱼类，它们将灭绝．take…from从…拿走．too many fishes from the sea 从海洋中捕捞过多鱼类．none没有一个； 没有人，没有一人； 没有一部分，没有一点．注意，原句中take为被动语态，本题为主动语态．故填take；none．
108．crowded；birth．细节理解题．考查人口问题．根据第二段"The world has become too crowded"所说，世界已变得很拥挤．所以需要用现代方法控制人口增长．crowded 拥挤的．become too crowded变得太拥挤．另外，根据倒数第二段"The world population will not rise so quickly if people use modern methods of birth control"可知，如果利用现代计划生育措施，人口增长就不会太快．birth为名词，意思是"出生"．birth control计划生育．modern methods of birth control现代计划生育措施．故填crowded；birth．
109．earth；cleaner．细节理解题．根据最后一段"if we educate people to think about the problems，we shall have a better and cleaner living place in the future"可知，如果教育人们考虑一下目前的问题，未来我们将拥有一个更加美好和干净的地方．the earth will be better and cleaner地球将更美好和干净．the earth地球．better and cleaner既美好又干净．文章首段就提到地球．故填earth；cleaner．
110．protecting； how．主旨大意题．考查文章主题．这篇文章主要介绍怎样解决环境问题．protect the environment保护环境．the importance of protecting the environment保护环境的重要性．how to solve the environmental problems怎样解决这些环境问题．故填protecting； how．
