解析

试题分析：本文通过现在与过去情况的对比,提出了保护环境的重要性。人们知道捕鱼太多会造成渔业资源的枯竭，也知道如果过多砍伐树木会造成森林的消失，更知道过量的废物排放会造成河流的污染,然而人们对此还是明知故犯，作者对此类现象在文中进行了分析,而且提出了相应的解决方法。
小题1:C考查对上下文的推理判断能力。根据下文There were few people on the earth, and natural resources seemed to be unlimited.可知此处是讲述过去的情况,而C选项In the past, man didn’t have to think about…..也是讲述过去的状况，所以C选项内容符合语境,故答案选C.
小题2:F考查对上下文的推理判断能力。上文作者提到世界人口的激增与污染等问题,纵观选项,F项内容涉及到了这些现象的后果,故能承接上文,答案选F.
小题3:D考查对上下文的推理判断能力。根据副词 However可知此处内容是关于污染的,而且和in most countries waste products are still put into rivers or into the sea构成转折关系,故答案选D.
小题4:A考查对上下文的推理判断能力。在本段中作者提到了一些解决问题的方法,比如生产粮食的土地比饲养动物的土地能够养活更多的人,因此人们要多吃蔬菜,少吃肉, 以及控制人口增长等,由此判断A选项内容能够起到引领下文的作用,故答案选A.
小题5:G考查对上下文的推理判断能力。作者在本段中提到了一些解决问题的方法,比如控制人口增长等 ，而G选项”学会资源再利用”也是解决问题的方法之一,内容符合语境,由此判断G为正确选项.
