主语可能是分词动作的执行者,句子的 主语也可能是分词动作的承受者。,但在一些表示说话者态度的固定表达方式中,分词短语的逻辑主语和句子的主语是不一致的。这种结构常见的有:,1)generally/strickly/+speaking,2)Judging from/talking of/allowing for.,3)Considering that/seeing that,/supposing that,注意:现在分词作状语的几个特性。,时间性,。与谓语动词同时发生,用一般时,如发生在谓语动作之前时则用完成式,having done,。,语态性,。与句子的主语之间的关系,是主谓关系或动宾关系。,人称一致性,。分词的逻辑主语就是句子的,主语。,1._ the program,they have to stay there for another two weeks.,A.Not

was,lost,in thought.,They were deeply,moved.,注意,:,被动结构与系表结构的区别,这两种结构形式都是,be+,过去分词。,这两种结构的主要区别是,:,被动语态强调所发生的动作,而系表结构表示的是主语的特点或状态。,The cup was broken by my little brother.,(,被动结构,),The cup is broken.(,系表结构,),2.,过去分词,作定语,过去分词,作定语,它的逻辑主语就是它所修饰的词,有以下三个特点,:,A.,及物动词的,过去分词作定语和它的逻辑主语的关系是被动的。所表示的时间概念是完成。,The building,built last year,can hold 1,000 people=The building,that was built last

is seen from the top of the hill,the town,=,When,the town is seen from the top of the hill,the town,2),作,原因状语,Deeply,moved,by the story,the children began to cry.,=,As/Because,they were deeply moved

引导并列句子,因此,前面也是个独立句子,故选C。,2._many times,he still couldnt understand it.A.Having been told B.To be toldC.He was told D.Though he was told,分析:,句中用逗号隔开,且无连词引导,因此,前面不是句子结构,只是句子的一个成分,故选A,用非谓语动词作状语。,二、分析逻辑主语,非谓语动词虽不能作谓语,但仍具有动词特点,其逻辑上的动作执行者就叫做逻辑主语。非谓语动词作状语时,其逻辑主语须和句子的真正主语一致。若不一致,则须加上自己的逻辑主语。,1._no buses,we have to walk home.,2._Sunday,I shall have a quiet day at home.,A.There being B.It were C.There were D.It being,分析:句1.表示“没有公共汽车”,应用“there be”结构,即逻辑主语是“the buses”,故选A。句2.同理选D。,三、分析语态,分析语态就是在确定逻辑主语之后,分析非谓语动词和逻辑主语在搭配使用时是主动还是被动关系。,1._from space,the earth looks blue.2._from space,we can see the earth is blue.A.Seen B.Seeing C.To see D.See,这两个题选项中的非谓语动词都没有加自己的逻辑主语,因此其逻辑主语就是句子的主语。,分析:句1.“地球被看”,表被动,故选A,用过去分词表被动。句2.我们“主动看”即表主动,故选B。,四、分析时态,,在选定了主动或被动后,还要考虑动作发生的时间问题,即时态。,1.The building _now will be a gym.2.The building _next year will be a gym.3.The building _last year is a gym.A.having been built B.to be builtC.being built D.built,分析:句1中 now 说明大楼正在被修,故用进行式,选C。句2中next year 说明大楼将在明年被修,故用表将来的不定式,选B。句3中 last year 说明大楼已被修,但不能选A,因为现在分词的完成式不能作定语,故用过去分词,选D。,Thank you!,GOODBYE,
