When DDT became available for civilian use in 1945, there were 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 the economy __7__of nature of all insects are good, but if they are killed, things __8__go out of kilter right away.” Another was Rachel Carson, who wrote to the Reader’s Digest to propose an article about series of __9__tests on DDT being conducted not far from which she lived in Maryland. __10__
答案及解析:
1.which—whose
whose在這里作關系限定詞,與effectiveness構成名次詞組在關系分句里作主語。whose的主語可以是人,也可以是物。
2.destroy—destroying
be limited to 詞組里的to并不是不定式標記to,而是介詞to,要謹訪介詞to“冒充”不定式to。其他類似的詞組還有be opposed to, object to, get used to等等。
3.cleaning—clearing
clean和clear這對形近而且意近的動詞容易被混淆,但是clean指“使某地方沒有灰塵,使干凈”,而clear強調“清理不需要的東西,而且clear 可與of連用,而clean很少。(這兩個詞的改錯之前也有遇到過,大家都要記住啦!)
4.caused—causing
此句中malaria-causing insects 相當于insects that caused malaria,因此是主動關系,所以應選擇-ing形式。
5.by-/
the Nobel Prize實際上是award的另一個賓語,還原成主動結構是…awarded the inventor the Nobel Prize.所以這里應刪掉by。
6.the-/
短語second thought或second thoughts意為“仔細斟酌,三思”,如:
Robert didn’t give a second thought to borrowing $2,000 from him.
7.discriminate-indiscriminate
discriminate有“區(qū)別”之意,indiscriminate意為“不加以選擇,不分青紅皂白”。從上下文來看DDT的特點是沒有分辨性:它既能殺死有害的昆蟲又能殺死有益的昆蟲。
8.but-and/so
本句的兩個意群的關系是順接,不是轉折,因此應選用順接的連詞,如and和so等。
9.^series-a
series這個名詞屬于單數復數同形,它經常與a和of構成詞組a series of表示“一系列的”。
10.which-where
from這個介詞后面應接一個介詞表具體方位,因此這里只能用表方位的副詞where。
