非谓语动词和从句的转换

非谓语动词和从句的转换----一.不定式（短语）与从句的关系1.不定式（短语）在句中作主语，其功能相当于一个主语从句，因此二者之间可以转换。

(1).To be able to help you is really an honor.(=That I’m able to help you)(2).He seemed to know the way.(=It seemed that he knew the way.)(3).Bush is said to have decided to attack North Korea.(= It is said that Bush has decided to attack North Korea.)2.不定式（短语）在句中作宾语或宾补，相当于一个宾语从句(1).We still don’t know when and where to build a school.(宾语)(=when and where we should build a school)(2).I advised him to go and see the doctor.(宾补)(=that he should go and see)(3).He thought it a great pity not to have invited her. .(宾语)(=That he hadn’t invited her.)3不定式（短语）在句中作表语.，相当于一个表语从句(1).My suggestion is for them to leave as soon as possible.(=that they should leave)(2).My chief purpose has been for them to get a good understanding.(=that they can get a good understanding)4.不定式（短语）在句中作定语.，相当于一个定语从句(1).The question will be discussed at the conference shortly to open in Beijing.(=that is shortly to open in Beijing)(2).All dead, I was the only one to grow up. (=that grew up)5.不定式（短语）在句中作目的．结果状语.，相当于一个目的．结果状语从句(１).He came to the area in order/so as to study the folk music there.(=in order/so that)(2).The lady was so excited as not to say a word.(=so excited that she could n’t…)7.不定式（短语）在句中作原因状语.，相当于一个原因状语从句(１)I trembled to think of being punished by the boss.(=because I though of being punished by the boss)(2).We were disappointed to have lost the game.(=that we have lost the game)二．动名词（短语）与从句的关系1. 动名词（短语）在句中作主语，相当于一个主语从句(１).Your going away (=That you went away) made the professor angry.(2).Mary’s not being made monitor (=That Mary was not made monitor ) made us sad.被动的动名词在句中作主语时一般不能省(3).Being called a fool(=That he was called a fool) hurt Bob badly.2. 动名词（短语）在句中作宾语或宾补语，相当于一个宾语从句(1).I remember being taken to Beijing(=that I was taken to Beijing) when I was five.(2).He admitted having married Mary to a soldier(=that he had married Mary to a soldier).3.动名词（短语）在句中作表语.，相当于一个表语从句(1).My duty is serving the people heart and soul (that I’ll serve the people heart and soul).(2).The problem is his not having prepared his lessons for the exam(=that he hasn’t prepared his lessons for the exam)(3).The difficulty is Mary’s being caught between the two trees(=that Mary is caught between the two trees).4.介词＋动名词（短语），相当于一个从句(宾语从句或同位语从句 0(1）He was afraid of being scolded by his mistake.(=that he was…)(2).He was astonished at her knowing you.(=that she knew you)(3).We heard the news of our team having won.(=that our team had won)三．分词（短语）与从句的关系1.分词（短语）作定语，相当于一个定语从句(1）The hospital was an old building built in 1931(=that was built in 1931).(2).Do you know the girl standing over there(=who is standing over there)?(3).The man speaking to us the other day(= who spoke to us the other day) has gone to Japan.本节值得注意的问题：现在分词短语作定语时，所表示的动作不能先于谓语所表示的动作，也不可以表示将来。

另外，一般不用现在分词的完成式作定语，所以，下列句子都是错的：Here is Mr. Li coming from Beijing. (应改为who has come from Beijing)Those having finished their work can go home now. (应改为who have finished)The man giving us a lecture last week left for Shenzhen this morning. (应改为who gave us)2.分词独立结构，相当于一个状语从句，其中伴随状语多与并列句转换(1）Weather permitting(=If weather permits), we’ll have the match tomorrow.(2).The dark clouds having disappeared(=When the dark clouds had disappeared), the sun shone again.(3).The monitor being ill(=As the monitor was ill) we’d better put the meting off.(4).Other things being equal(=If other things are equal), I’d buy the black dress.(5).Given more time(=If we were given more time), we could have done it better.(6).He came back, his hands tied to his back(=and his hands were tied to his back).3.分词短语，相当于一个状语从句(1）On arriving(=As soon as I arrive) there, I’ll telephone you.（时间）(2).(While)waiting(=While I was waiting )for the bus, I caught sight of her．（时间）(3).Educated(=As he was educated ) by the party, he became a great fighter.（原因）(4).Not having received(=Because I hadn’t received an answer, I wrote to him again.（原因）(5).(If) given(=If we had been given )enough time, e could have done it better.（条件）(6).(Though) having made(=Though he had made) great achievements, he didn’t pride.(让步)４．分词短语作状语，可表伴随，结果，相当于and 的并列句，也可和with 转换(1）He died, leaving his daughter much money. ()(=with),(=and left)(2).The teacher entered the lab, followed by our students.(=and he was followed by our students =with us following him=and we followed him) 5.分词短语在句中作宾语或宾语补足语，相当于一个宾语从句(1）He found the windows broken.(=He found that the windows were broken.)(2).I felt my heart beating fast at the news of bomb explosion.(=I felt that my heart was besting fast at the news of bomb explosion)四．特殊转换1. 动名词复合结构相当于从句(1）Sophia’s having seen them(=That Sophia had seen them) didn’t surprised us.(2).I can’t bear his (him) staying up so late(=that he stays up so late).(3).We encourage students’ living in the school(=that students live in the school).(4).What was disappointing was our not being able to go for a picnic (that we were not able to go for a picnic).2. there+being+其他成分(1）There being nothing to do, we played games.(=Because there was nothing to do) (原因) (2).They closed the store, there being no customers.(=Because there was no customers) (原因)。
