秘訣三、being done 表示“正在被”,一般不作狀語,只作定語。非謂語動詞的完成時形式to have done或having done強調(diào)該動作發(fā)生在句子謂語動詞之前。
例5.to reach them on the phone, we sent an email instead.
A. Fail B. Failed
C. To fail D. Having failed
【解析】根據(jù)句意“我們沒有打通電話,就給他們發(fā)了個郵件”,沒有打通電話應(yīng)該發(fā)生在發(fā)郵件之前,所以用having done,答案為D。
例6.Tim Bemers-Lee is generally considered _____ the World Wide Web, on which all the information is shared by all.
A. to have founded B. having founded
C. founding D. to found
【解析】根據(jù)句意,Tim Bemers-Lee創(chuàng)立萬維網(wǎng)應(yīng)該是過去的事情,而且be considered后面應(yīng)該用動詞不定式,所以應(yīng)該用to have done,答案為A。
