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.

1.       【答案】A. include
【解析】本題測試詞義搭配.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(我們的代表團(tuán)里包括2位翻譯)involve 雖然也有“包含”的意思，但其后所接的名詞大多數(shù)是非實體性名詞，所以involve 的確切含義是“（=have s a necessary consequence）必然包括某種結(jié)果，牽涉到”，例如：The war involved a great increase in the national debt.（戰(zhàn)爭必然使國家負(fù)債驟增。）根據(jù)上下文的意思 ( 貴.州,學(xué).習(xí),網(wǎng) )hTTp://wWw.gZu521.cOm來看，此處指“昆蟲中有某些人類比較大的天敵”，句中enemies是實體名詞，故此體應(yīng)選include. cover 也有“包括”之意，但主要是指“談到，涉及到”，例如：1) The discussion covered a wide range of subjects. (這次討論涉及到范圍廣闊的議題。) 2）His studies covered a wide field.(他的研究涉及到很大的領(lǐng)域) cover 作“包括，包含”解時一般不結(jié)具體的事物或動物名詞。consist 后接of,意為“由…..組成”�？梢�，本題答案非A 莫屬。
2.       【答案】C. it
【解析】本題測試結(jié)構(gòu)搭配.it 是形式賓語，其實際賓語是for us to live in the world.
3.       【答案】B. for
【解析】本題測試結(jié)構(gòu)搭配. were it not for sth. 是虛擬條件句，意為“要不是….,要是沒有….的話”。
4.       【答案】C. owe
【解析】本題測結(jié)構(gòu)型詞義搭配. owe…..to…把…..歸功于….: He owed his success o luck more than to capacity. contribute to 有助于，促進(jìn)，加�。篊ars contribute to air pollution. (汽車加劇了空氣污染)；devote sth. to 奉獻(xiàn)，致力于；dedicate … to 奉獻(xiàn)；均不符合題意。
5.       【答案】B. put
【解析】本題測試詞義搭配.put together 加在一起。put together 在句中是過去分詞短語作定語，修飾前面的all of them.
6.       【答案】A. number
【解析】本題測試詞義搭配. insect 是可數(shù)名詞。此處是指昆蟲的“數(shù)目”，故應(yīng)選number. An (或 the) amount of +不可數(shù)名詞（單數(shù)），故不能入選。plenty of +可數(shù)名詞（復(fù)數(shù)）或不可數(shù)名詞（單數(shù)），意為“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. (許多失業(yè)男子)proportion 比例。
7.       【答案】B. Moreover
【解析】本題測試邏輯搭配.moreover 意為“此外，而且”，正合題意。
8.       【答案】D. harm
【解析】本題測試詞義搭配. do harm to …對某人有害，正合題意。do damage to sth. 對….造成損害，與題意不符。do good to sb./sth. 對…有好處，與題意相悖。do與ruin不搭配，通常說cause ruin, bring about ruin, lead to ruin等
9.       【答案】A. as
【解析】本題測試結(jié)構(gòu)搭配.as 引導(dǎo)非限定性定語從句，例如：As you know, China is a country with a large population. (正如你所知道的，中國是一個人口眾多的國家)
