　　DDT, the most powerful pesticide the world had ever known,exposed nature’s vulnerability.Unlike most pesticides, which effect- __1__ tiveness is limited to destroy one or two types of insects,DDT is __2__ capable of killing hundreds of different kinds at once. Developed in 1939, it firstdistinguished itself during the World War II, cleaning __3__ South Pacific islands of malaria-causedinsects for U.S. troops, while __4__in Europe being used as an effective de-lousing power. Its inventorwas awarded by the Nobel Prize. __5__ When DDT became available for civilian use in 1945, therewere only a few people who expressed the second thought about this __6__ new miracle compound.One was nature writer Edwin Way Teale,who warned, “A spray as discriminate as DDT can upset theeconomy __7__ of nature of all insects are good, but if they are killed, things __8__ go out of kilterright away.” Another was Rachel Carson, who wrote to the Reader’s Digest to propose an articleabout series of __9__ tests on DDT being conducted not far from which she lived in Maryland. __10__　　答案：

　　1.which—whose。whose在这⾥作关系限定词，与effectiveness构成名次词组在关系分句⾥作主语。whose的主语可以是⼈，也可以是物。

　　2.destroy—destroying。be limited to 词组⾥的to并不是不定式标记to，⽽是介词to，要谨访介词to“冒充”不定式to。其他类似的词组还有be opposed to, object to, get used to等等。考试⼤

　　3.cleaning—clearing。clean和clear这对形近⽽且意近的动词容易被混淆，但是clean指“使某地⽅没有灰尘，使⼲净”，⽽clear强调“清理不需要的东西，⽽且clear 可与of连⽤，⽽clean很少。（这两个词的改错之前也有遇到过，⼤家都要记住啦！）

　　4.caused—causing。此句中malaria－causing insects 相当于insects that caused malaria，因此是主动关系，所以应选择-ing形式。

　　5.by－/。the Nobel Prize实际上是award的`另⼀个宾语，还原成主动结构是…awarded theinventor the Nobel Prize.所以这⾥应删掉by。

　　6.the－/。短语second thought或second thoughts意为“仔细斟酌，三思”，如：Robert didn’t give asecond thought to borrowing $2,000 from him.

　　7.discriminate－indiscriminate。discriminate有“区别”之意，indiscriminate意为“不加以选择，不分青红皂⽩”。从上下⽂来看DDT的特点是没有分辨性：它既能杀死有害的昆⾍⼜能杀死有益的昆⾍。　　8.but－and/so。本句的两个意群的关系是顺接，不是转折，因此应选⽤顺接的连词，如and和so等。

　　9.^series－a。series这个名词属于单数复数同形，它经常与a和of构成词组a series of表⽰“⼀系列的”。

　　10.which－where。from这个介词后⾯应接⼀个介词表具体⽅位，因此这⾥只能⽤表⽅位的副词where。
