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.

　　Spiders are not insects, 9 many people think, 10 even nearly related to them. One can tell the 11 almost at a glance, 12 a spider always has eight legs but an insect never more than six.

　　How many spiders are 13 in this work on our 14 ? One authority 15 spiders made a 16 of the spiders in a grass field in the south of England, and he estimated that there were more than 2 250 000 in one acre; that is 17 like 6000 000 spiders of different kinds on a football field. Spiders are busy for at least half the year in killing insects. It is 18 to make more than the 19 guess at how many they kill, but they are hungry creature, not 20 with only three meals a day.

　　Text 6答案

　　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。

　　2. 【答案】C. it

　　【解析】本题测试结构搭配.it 是形式宾语，其实际宾语是for us to live in the world.

　　3. 【答案】B. for

　　【解析】本题测试结构搭配. were it not for sth. 是虚拟条件句，意为“要不是….,要是没有….的话”。

　　4. 【答案】C. owe

　　【解析】本题测结构型词义搭配. owe…..to…把…..归功于….: He owed his success o luck more than to capacity. contribute to 有助于，促进，加剧：Cars contribute to air pollution. (汽车加剧了空气污染);devote sth. to 奉献，致力于;dedicate … to 奉献;均不符合题意。

　　5. 【答案】B. put

　　【解析】本题测试词义搭配.put together 加在一起。put together 在句中是过去分词短语作定语，修饰前面的all of them.

　　6. 【答案】A. number

　　【解析】本题测试词义搭配. insect 是可数名词。此处是指昆虫的“数目”，故应选number. An (或 the) amount of +不可数名词(单数)，故不能入选。plenty of +可数名词(复数)或不可数名词(单数)，意为“很多，大量的”，用于肯定句中，例如：1) There was plenty of work for girls of her age. 2) There are plenty of men out of work. (许多失业男子)proportion 比例。

　　7. 【答案】B. Moreover

　　【解析】本题测试逻辑搭配.moreover 意为“此外，而且”，正合题意。

　　8. 【答案】D. harm

　　【解析】本题测试词义搭配. do harm to …对某人有害，正合题意。do damage to sth. 对….造成损害，与题意不符。do good to sb./sth. 对…有好处，与题意相悖。do与ruin不搭配，通常说cause ruin, bring about ruin, lead to ruin等

　　9. 【答案】A. as

　　【解析】本题测试结构搭配.as 引导非限定性定语从句，例如：As you know, China is a country with a large population. (正如你所知道的，中国是一个人口众多的国家)

　　10. 【答案】C. nor

　　【解析】本题测试逻辑搭配. not … as 翻译时否定要转移到as 上。

　　本句译文：蜘蛛不像许多人想的那样是昆虫，它们甚至与昆虫几乎无关。nor引导的是延续否定句，其中省略了主语与系动词。如果把主语与系动词补上，则应为：…nor are spiders even nearly related to them. not nearly 意为“全然不”，此句中的not的否定意义由nor来体现。此外，有些语法学家认为，此类句子中nor连接的是两个并列成分，例如：For ten days I did not see him nor telephone him.
