易错点5对现在完成进行时理解不透彻
【易错题】--- I’m s来源:91 考试网ure Andrew will win the first prize in the final.
--- I think so. He _______ for it for months.
A. is preparing B. was preparing C. had been preparing D. has been preparing
易错点7混淆各种时态的被动语态
【易错题】Why does the Lake smell terrible?
-Because large quantities of water ______.
A. have polluted B. is being polluted
C. has been polluted D. have been polluted
【中公专家解析】考生容易误选B项，原因是不知道large quantities of修饰主语时，谓语动词应该用复数，再就是以为大片的水域正在被污染。根据前一个分句可知所填动词表示过去发生的动作对现在产生的影响，时态用现在完成时，动词与主语是动宾关系，故应用被动语态。
【答 案】D
(6)was/were being done过去进行时：A meeting was being held when I was there.
(7)shall/will be done一般将来时：Hundreds of jobs will be lost if the factory closes.
(8)should/would be done过去将来时：The news would be sent to the soldier’s mother as soon as it arrived.
(2)在need，want，require，bear等词的后面，动名词用主动形式表示被动意义，其含义相当于动词不定式的被动形式。如：The house needs repairing(to be repaired).这幢房子需要修理。
(3)形容词worth后面跟动名词的主动形式表示被动意义，但不能跟动词不定式;而worthy后面跟动词不定式的被动形式。来源:91考试网 91EXAm.org如：The picture-book is well worth reading.(The picture-book is very worthy to be read.)
