不定式作定語(yǔ)的用法

1、不定式作定語(yǔ)的用法不定式及其短語(yǔ)作定語(yǔ)，與其他短語(yǔ)作定語(yǔ)一樣，一般都放在被修飾的詞之后，通常表示一個(gè)將來(lái) 的動(dòng)作，有時(shí)也可以表示某一過(guò)去的特定動(dòng)作。一些名詞后常用不定式作定語(yǔ)，如：chance(機(jī)會(huì))，way(方法)，time(時(shí)間)等；另外，the first,the seco nd,the last,the only等作名詞或者它們作形容詞用來(lái)修飾代詞，它們或它們所修飾的代詞后，也常用不定式作定語(yǔ)。不定式作定語(yǔ)時(shí)，不定式與被修飾詞之間存在的關(guān)系復(fù)雜，有的是主謂關(guān)系；有的是動(dòng)賓關(guān)系；有 的是動(dòng)狀關(guān)系，還有的不存在主謂、動(dòng)賓、動(dòng)狀關(guān)系。1、主謂關(guān)系的(1)We must find a pers

2、on to do the work.(2) There is no one to take care of her.(3) In my family,my mother is always the first one to get up.(4) He is always the first to come and the last to leave.(5) We n eed some one to go and get a doctor.2、動(dòng)賓關(guān)系的如果不定式與被修飾的詞在邏輯上存在動(dòng)賓關(guān)系，不定式里的動(dòng)詞必須是及物動(dòng)詞。注意：是及物動(dòng)詞的，后面不要再加賓語(yǔ)，因?yàn)榍懊娴谋恍揎椩~是它的賓語(yǔ)；是

3、不及物動(dòng)詞的， 要加上適當(dāng)?shù)慕樵~或副詞讓它變成及物動(dòng)詞，只有這樣，它才能帶上前面的賓語(yǔ)。(1) He has a lot of books to read.(2) I would like a magazine to look at.(3) Here is some advice for you to follow.(4) Do you have any thi ng else to say?(5) There is no one to take care of.(6) She has nothing to worry about.3、動(dòng)狀關(guān)系的 被修飾詞如果是不定式里動(dòng)詞的狀語(yǔ)，應(yīng)多用介詞短

4、語(yǔ)。由于被修飾詞前沒有介詞，所以只能在不定式里的動(dòng)詞后加介詞。(1) Please give me some paper to write on.(2) Lets find a room to put these thi ngs in (3) I have no house to live in.(4) He has no pen to write with.(5) There are five pairs to choose from.4、 不存在主謂、動(dòng)賓、動(dòng)狀關(guān)系的被修飾詞與不定式里的動(dòng)詞不存在主謂、動(dòng)賓、動(dòng)狀關(guān)系的，被修飾詞多是些抽象名詞。(1) I have no time to g

5、o to the movie.(2)Theres no need to send for a doctor. (3) Wheres the best place to meet?(4) Is that the way to do it?(5) Im not sure about his ability to complete the task alone.現(xiàn)在分詞作定語(yǔ)狀語(yǔ)的用法現(xiàn)在分詞在句中起形容詞和副詞的作用。現(xiàn)在分詞用定語(yǔ)時(shí)相當(dāng)于一個(gè)定語(yǔ)從句； 作狀語(yǔ)表示時(shí)間、原因、條件等時(shí)相當(dāng)于一個(gè)狀語(yǔ)從句。然而，我們?cè)谑褂矛F(xiàn)在分詞時(shí) 應(yīng)注意兩方面的問題。一、作定詛現(xiàn)在分詞短語(yǔ)作定語(yǔ)逋常置所修馀的名詞

6、或代詞Z后，現(xiàn)在分詞短語(yǔ)作方置定語(yǔ) 時(shí)，應(yīng)注意下列三點(diǎn)：1. 現(xiàn)在分詞表示的動(dòng)作和謂語(yǔ)動(dòng)詞表示的動(dòng)作是一先一后發(fā)生而不是同時(shí)發(fā)生時(shí)， 不能用現(xiàn)在分詞作定語(yǔ)，應(yīng)使用定語(yǔ)從句表示。如：The teacher criticized the stude nt hav ing broke n the win dow.The teacher criticized the stude nt who had broke n the win dow.Do you know anyone hav ing lost a car ? Do you know anyone who have lost a car ?2.

7、 be ing可用狀語(yǔ)或補(bǔ)語(yǔ)，但不可作定語(yǔ)。如：Anybody being outside after ten o clock will be criticized. T)Anybody who is outside after ten o clock will be criticized.3表示經(jīng)常性或已完成的非進(jìn)行動(dòng)作的時(shí)候，不用現(xiàn)在分詞作定語(yǔ)。例如：供） The boy bringing us milk everyday is my brother.T） The boy who brings us milk everyday is my brother.二、作狀詛現(xiàn)在分詞作狀詛,我心必須

8、注意以下阿點(diǎn):1現(xiàn)在分詞作狀語(yǔ)與謂語(yǔ)動(dòng)詞的時(shí)間關(guān)系。現(xiàn)在分詞所表小-的動(dòng)作與謂語(yǔ)動(dòng)近表小的動(dòng)作同時(shí)發(fā)生時(shí)，現(xiàn)在分詞用一般式。女口：The secretary worked late into the ni ght, prepari ng a long speech for the preside nt. He sent me an E-mail, hoping to get further information.現(xiàn)在分詞所表小的動(dòng)作先:謂詛動(dòng)詞的動(dòng)作時(shí)，現(xiàn)在分同要用完成式。如：Havi ng suffered from heart trouble for years, Professor W

9、hite has to take some medici ne with him whe never he goes.Having fini shed his homework, the boy went out to play football.2. 現(xiàn)在分詞作狀語(yǔ)與主語(yǔ)的關(guān)系。現(xiàn)在分詞作狀語(yǔ)時(shí)，其邏輯主語(yǔ)與句子主語(yǔ)必須 保持一致。如果不一致，分詞應(yīng)有自己的邏輯主語(yǔ)，構(gòu)成獨(dú)立主格結(jié)構(gòu)。如：Look ing out of the win dow of our hotel room, we could see lots of mountains around.They came into the

10、 classroom, talking and laughing.Mr. Smith being absent, the meeting had to be put off.It being a fine day, we all wan ted to go out ing.3. 現(xiàn)在分詞作狀語(yǔ)時(shí)，前面可用連詞whe n, while, once等。如：Whe n talk ing to you, I always feel happy.Be careful while crossing the street.4. 現(xiàn)在分詞作狀語(yǔ)時(shí)與主語(yǔ)之間不能有并列連詞or, and, but等,因?yàn)椴⒘羞B詞

11、連接 的是兩個(gè)并列的成分，而分詞短語(yǔ)只是全句的一個(gè)狀語(yǔ)部分，但分詞與主語(yǔ)之間可用逗號(hào)。如：Having been told many times, but he still couldn t understand it.-下 Having been told many times, he still couldn t understand it.過(guò)去分詞的主要用法非謂語(yǔ)動(dòng)詞除了包括不定式、動(dòng)名詞和現(xiàn)在分詞之外，還包括過(guò)去分詞。過(guò)去分詞又 稱-ed分詞，在句中可以構(gòu)成句子的謂語(yǔ)和復(fù)合賓語(yǔ)，也可以用作句子的表語(yǔ)、定語(yǔ)和狀 語(yǔ)。一、過(guò)去分詞構(gòu)成謂語(yǔ)和作表語(yǔ)的情況1. 和某些助動(dòng)詞一起構(gòu)成句子的謂語(yǔ)：
