解析

试题分析：这篇短文主要讲述了在过去，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（资源）似乎是无限的（无限的）。今天不同了，世界已变得过于拥挤。我们正在利用我们的自然资源，在同一时间太快，我们与危险化学品污染我们的环境（化学制品）。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。
小题1:单词填空题。根据短文提示，If we continue to do this。如果我们还继续这样做，在地球上人类将不能生存。故填earth not。
小题2:英汉互译题。Our natural resources我们的自然资源，last longer持续时间更成，if引导的条件状语从句。根据上下文故填如果我们学会循环利用自然资源的话，那自然资源将会维持更长的时间。
小题3:回答问题。问我们怎样能保护鱼类？根据文中with modern fishing methods(方法) , more and more fish are caught.和We realize that if rivers are polluted with waste products from factories, fish will die.这些情况应该是禁止做的，故答案1,Don’t take too many fish from rivers and the sea. 2,Stop polluting rivers and the sea with waste products from factories.
小题4:同义句题，根据文中weknow that if the population of the world is becoming larger and larger, 可知答案为The population of the world is becoming larger and larger .
小题5:主旨题。通读全文可知本文主要讲保护环境，所以答案为In a word ,It is important to protect our environment.
