Why, you may wonder, should spiders be our friends? Because they destroy so many insects, and insects 1 some of the greatest enemies of the human race. Insects would make 2 impossible for us to live in the world. They would devour (eat up quickly) all our crops and kill our flocks and herds, were it not 3 the protection we get from insect-eating animals. We 4 a lot to the birds and beasts who eat insects but all of them 5 together kill only a fraction of the 6 destroyed by spiders. 7 , unlike some of the insect eaters, spiders never do the least 8 to us or our belongings.

1. 【答案】A. include
【解析】本题测试词义搭配.include(= bring in as a part of the whole) 包括，包含：1) The book includes two chapters on grammar. 2) The plan includes most of your suggestions. 3) Our delegation included two interpreters(我们的代表团里包括2位翻译)involve 虽然也有“包含”的意思，但其后所接的名词大多数是非实体性名词，所以involve 的确切含义是“（=have s a necessary consequence）必然包括某种结果，牵涉到”，例如：The war involved a great increase in the national debt.（战争必然使国家负债骤增。）根据上下文的意思 ( 贵.州,学.习,网 )hTTp://wWw.gZu521.cOm来看，此处指“昆虫中有某些人类最大的天敌”，句中enemies是实体名词，故此体应选include. cover 也有“包括”之意，但主要是指“谈到，涉及到”，例如：1) The discussion covered a wide range of subjects. (这次讨论涉及到范围广阔的议题。) 2）His studies covered a wide field.(他的研究涉及到很大的领域) cover 作“包括，包含”解时一般不结具体的事物或动物名词。consist 后接of,意为“由…..组成”。可见，本题答案非A 莫属。
