1. We often provide our children with toys, footballs or basketballs, _______ that all
children like these things.
A. thinking B. think C. to think D. thought
解析:A. 逻辑主语we与think是主动关系,根据语义,所有的孩子喜欢这些东西,所以选A.thinking。
2.Whenever he was asked why hewas late for class, he would answer carelessly, always
______ the same thing.
A. saying B. said C. to say D. having said
解析:A. 逻辑主语he与say是主动关系,所以选A.saying。
3.Don't sit there________ nothing. Come and help me with this table.
A. do B. to doC. doing D. and doing
解析:C. 此句为祈使句。祈使句的主语为说话的对象you,即do的逻辑主语you与之构成主动关系,且do伴随着sit,故选C . doing。非谓语中只有现在分词能做伴随状语,并 表主动。
4.When ______ different cultures, we often pay attention only to the differences without noticing the many similarities.
A. compared B. being compared C. comparing D. having compared
解析:C. when从句补充完整为when we compare different cultures, 逻辑主语we与 compare为主动关系,所以选C.comparing。D项表示发生在谓语动词之前的动作,故不合适。
5.The wild flowers looked like a soft orange blanket__________ the desert.
A. covering B. covered C. cover D. to cover
解析:A. blanket与cover为主动关系,因此选A.covering。
解题关键:
第一,现在分词的主动语态doing与逻辑主语是主动关系,被动语态being done与逻辑主语是被动关系。如:(1) The front door being repaired, we had to enter through the back door. “being repaired”与逻辑主语“the front door”是被动关系。(2) The man, pretending to read a newspaper, glanced at the man seated next to a woman. “pretending”的逻辑主语“the man”与之构成主动关系。
第二,现在分词的时态是通过其动作和句子的谓语动词的动作的先后来确定的。doing /being done表示与谓语动词同时或之后发生,having done /having been done表示动作发生在谓语动词之前。如:(1) Not having received a reply, he decided to write again.“not having received”发生在“decided”之前。(2) The secretary worked late into the night, preparing a long speech for the president.“preparing”与谓语动词“worked”同时进行。
总之,解答非谓语动词题牢记“三部曲”:①确定选项在句中所作的成分,确定使用非谓语还是谓语。②明确非谓语动词的逻辑主语,在主动和被动中做出选择。③结合主句的谓语动词判断动作是已经完成的、正在进行的还是将要去做的。
