教师招聘英语知识点：非谓语动词（二）

对非谓语动词做状语、定语和宾语补足语的逻辑主语不明确

【易错题1】_______twice,the postman refused to deliver our letters unless we changed our dog.

A.being bitten

B.bitten

C.having bitten

D.to be bitten

【解析】考生容易误选A项，认为这里应该用被动语态。其实过去分词也表示被动，知识过去分词表示的被动是已经完成的被动，为现在分词的被动是正在进行的被动。the postman与bite之间是被动和完成的关系，所以答案为B。

【答案】B

【错因透视】过去分词短语作状语，与句子的主语是动宾关系，而且表示已经完成的动作。作状语的过去分词短语改写为状语从句的时候，往往是改为被动语 态形式。如：Seen from the hill(=When it is seen from the hill)，the city looks magnificent.Depressed(=Since he was depressed), he went to see hiselder sister。They came in，followed by some children.=They came in and were followed by some children.更多真题及资料请加小编微信65210638领取
