英語四級考試語法精要

　　一、動名詞

　　1. 某些動詞后要接動名詞

　　某些及物動詞后能用動名詞而不能用不定式作賓語，其中最常用動詞的有admit, avoid, appreciate, complete, consider, delay, deny, dislike, enjoy, escape, excuse, fancy, finish, forgive, involve, imagine, can’t help, mind, miss, postpone, practise, prevent, quit, resent, risk, resist, suggest等。

　　She suggested spending another day in the mountain area.

　　There’s no way to escape doing the work.

　　She is considering asking her employer for a rise.

　　Note:

　　① 在need、want、require、deserve等動詞后的動名詞相當(dāng)于不定式的被動式

　　The clock needs/wants repairing. (=The clock needs/wants to be repaired)

　　The disabled deserve respecting. (=The disabled deserve to be respected.)

　　② 在like、hate、prefer等動詞后,如果表示一般傾向,則用動名詞作賓語;如果指具體的某次發(fā)生在將來的行動，則要用不定式。

　　I like reading books of this kind, but I don’t like to read that book.

　　She prefers walking to cycling.

　　I prefer to stay at home today.

　　③ 在remember、forget、regret等動詞后,如果用動名詞作賓語，則表示該賓語的動作發(fā)生在動詞謂語的動作之前;如果用不定式作賓語，則表示賓語的動作發(fā)生在動詞謂語的動作之后

　　I remembered locking the door. (=I remembered that I had locked the door.)

　　I remembered to lock the door (=I remembered that I was to lock the door.)

　　I regret telling you about it. (=I regret that I told you about it.)

　　I regret to tell you he has fallen ill. (=I regret that I am to tell you he has fallen ill.)

　　2. 動名詞作介詞的賓語

　　動名詞可作介詞的賓語，與介詞一起構(gòu)成介詞短語，在句中作定語、狀語或表語。

　　His dream of becoming a successful writer has come true.

　　She left without saying goodbye to us.

　　動名詞作介詞的賓語常用在某些詞組后面。這類常用的詞組主要有：be accustomed to, believe in, confess to, dream of, feel like, give up, insist on, be interested in, look forward to, object to, have an (no) objection to, pay attention to, put off, be responsible for, succeed in, be tired of, be (get) used to, worry about,等。

　　He has made up his mind to give up smoking.

　　3. 帶邏輯主語的動名詞

　　動名詞可以有邏輯主語，其構(gòu)成形式為“名詞或代詞的所有格+動名詞”。帶邏輯主語的動名詞又稱為動名詞的復(fù)合結(jié)構(gòu)，在句中用作主語,賓語,表語和介詞的賓語。在非正式語體中，如果動名詞的復(fù)合結(jié)構(gòu)在句中作賓語，也可以賓格來充當(dāng)動名詞的邏輯主語。但考生需注意的是，在各種英語測試中，專家們?nèi)詧猿衷谡秸Z體中用代詞的所有格來作動名詞的邏輯主語。

　　What do you plan to do tomorrow?

　　She hated to move from such a nice village.

　　In class teachers should try to get feedback from their students

　　2. 不定式的被動式

　　不定式有被動式，當(dāng)不定式的邏輯主語是這個不定式所表示的動作的承受者，不定式要用被動式，在句中可作主語，賓語，定語，狀語，復(fù)合賓語等。作定語時，通常表示在謂語動作后將要發(fā)生的動作。

　　The last question to be discussed today is how to do the job more efficiently.

　　She preferred to be given more difficult work to do.

　　3. 不定式的完成式

　　當(dāng)不定式的動作發(fā)生在謂語動詞的動作之前，不定式要用完成式，在句中可作賓語，狀語以及構(gòu)成復(fù)合賓語，復(fù)合謂語。

　　What we want is for you to understand the matter clearly.

　　I sent him some pictures for him to see what Paris is like.

　　6. 帶疑問詞的不定式短語

　　不定式前可以加某些疑問代詞，如who、what、which,或疑問副詞，如when、where、how、why等，構(gòu)成一種特殊的不定式短語，可在句子中作主語、賓語、表語或狀語等。

　　三、分詞

　　1. 現(xiàn)在分詞與過去分詞的區(qū)別

　　現(xiàn)在分詞與過去分詞的區(qū)別主要體現(xiàn)在時間和語態(tài)上。現(xiàn)在分詞表示正在進行的動作并表示主動的意義，而過去分詞表示已經(jīng)完成的動作并表示被動的意義。比較：

　　a changing world(一個變化著的世界);a changed world( 一個已經(jīng)起變化的世界)

　　surprising news(令人驚訝的消息);surprised people(感到驚訝的人們)

　　2. 分詞作狀語

　　作狀語時，表示時間、原因、方式、結(jié)果、條件、讓步和伴隨情況等。另外，作狀語時，它的邏輯主語應(yīng)與句子的主語一致。

　　Hearing the news, he heaved a sigh of relief.

　　Given another chance, I’ll do it much better.

　　3. 分詞作定語

　　分詞常用來修飾名詞或代詞作定語。單個的分詞作定語時，通常放在被修飾詞之前;分詞短語作定語時，通常放在被修飾詞之后。但有些單個的過去分詞作定語時，也可放在被修飾詞之后。

　　He’s a spoilt child.

　　The man standing over there is our new English teacher.

　　Where are we to get the material needed?

　　4. 分詞作賓語補足語

　　分詞可在感覺動詞和使役動詞后作賓語補足語。常用的感覺動詞主要有：see, hear, notice, watch, find, observe, smell等。常用的使役動詞主要有：get, have, keep, leave, set, make, let等。此外，分詞還可在want, like, wish, order等表示希望、要求、命令等意義的動詞后作賓語補足語。

　　She watched her baby sleeping.

　　I got my hair cut.

　　I don’t want you worrying about me.

　　5. 分詞與連詞的連用

　　分詞可與各種連詞(如：when, while, once, until, if, unless, though, although, even if, as, as if, as though等)連用。連詞+分詞(短語)的結(jié)構(gòu)在句中作狀語，相當(dāng)于狀語從句。

　　She’ll get nervous when speaking in public.

　　He went on talking, though continually interrupted.

　　6. 分詞的獨立結(jié)構(gòu)

　　分詞作狀語時，其邏輯主語與句子的主語應(yīng)該一致;否則，分詞應(yīng)有自己的邏輯主語，構(gòu)成分詞的獨立結(jié)構(gòu)。獨立結(jié)構(gòu)一般位于句首，作伴隨狀語以及在科技文章中表示附加說明時，它常位于句末。分詞的獨立結(jié)構(gòu)由名詞、代詞+分詞構(gòu)成，可以表示時間、原因、條件、方式或伴隨情況等。

　　Weather permitting, the football match will be played on Wednesday.

　　Her son having been sent to school, she began to do some shopping.

　　He returned three days later, his face covered with mud and his clothes torn into pieces.

　　完成進行式 to have been doing

　　完成式: 不定式的一般形式所表示的動作, 通常與主要謂語表示的動作(狀態(tài))同時(或幾乎同時)發(fā)生, 或是在它之后發(fā)生. 假如不定式所表示的動作, 在謂語所表示的動作(狀態(tài))之前發(fā)生, 就要用不定式的完成式。

　　完成進行式: 在謂語所表示的時間之前一直進行的動作, 就要用不定式的完成進行式.

　　The struggle was known to have been going for twenty years.

　　We are happy to have been working with you.

　　She hated to be flattered.

　　This is bound to be found out.

　　c. One of our main tasks now is to mechanize agriculture.

　　d. Do you have anything to declare?

　　e. We have come to learn from you.

　　不帶to 的不定式:

　　在“動詞+ 賓語+不定式”結(jié)構(gòu)中, 如果動詞是表示感覺意義的see, hear, watch, smell, feel, notice等, 或是表示“致使”意義的 have, make, let等, 其后的不定式結(jié)構(gòu)不帶to.

　　John made her tell him everything.

　　這類結(jié)構(gòu)轉(zhuǎn)換為被動語態(tài)時, 后面的不帶to 的不定式一般還原為帶to 的不定式.
