高三英語語法知識點1

情態動詞

一.表示許可：有may, might, can, could。其中might. could則語氣較委婉，但回答由他們引起的問句時，則不用might,could而用can。

1)May Might Can Could I keep the book for a few days? Yes, you can.

否定形式可用maynot, can not或must not，不用might not。

2)Visitorsmay not (或can not/mustn't) touch the button.

二、表示能力：can;be able to. be able to用於各種時態。在一般過去時中，若指“能夠並且通過某種努力完成某樁事”，我們必須用be able to。

1)Cats can are able to climb trees very quickly.

2)A big fire broke out last night, but everyone was able to escape from thehouse.

三、表示“責任和義務”的情態動詞有must(主觀),haveto(客觀), mustn’t 表示“不可以、不允許”，而have to否定形式：not have to/ needn't。

1)As there was no bus, we had to walk back home. (客觀條件)

2)You mustn't shout like that to your parents. (不可以、不允許)

3)You don't have to needn’t work if you don't feel well.

四、用於推測：must,may, might, can, could . 但疑問句中只能用can, could.

1)He looks pale. He__________ be ill.

2)---Who _____it be? It _____(not) be Mr. Smith, for he has just left forParis.

---It________be Mr. Brown, for he has something to discuss with me.

3)He said he didn't feel very well. He _____(not) come to the meeting thisevening.

(2. can, can’t, must 3. maymight not)

▲注意:表推測時 must, should (ought to) , may, could , might 可能性依次遞減。should, ought to“應該…”較多地用於預測將來的事。can表示理論上的可能性，用於泛指, could,might表示事實上的可能性，用於特指具體的，可能將要發生的事。

1)He should be back by now. 他現在該回來了。

2)The teacher has explained it several times. There ought to be no problem forthem.

4)A dog can be dangerous to you 狗可能給人帶來危險。(有這種可能性)

Thisdog is very clever. It may (或might/could) help you find your key.

這條狗非常聰明，他可能會幫助你找到鑰匙。指具體的事有可能發生。

一、非謂語動詞

“非謂語動詞”可分爲動詞不定式、動名詞和分詞.它在句子中的作用很多：除了不作謂語外,它可以充當主語、賓語、表語、定語、狀語與複合賓語(主語補語或賓語補語).有些及物動詞後面接不帶to的不定式作複合賓語.這些動詞歸納如下：一感(feel).二聽(hear,listento),三讓(have,1et, make),四看(see,watCh,notice,observe).再加上help somebody(to)dosomething和美國英語look at somebody do somthing.還有“二讓”屬特殊：get somebody to dosomething 與keep somebody doing.而有些及物動詞後面接動名詞(the -ing form)作賓語.這些動詞歸納爲一句話：Papa Cmakes friends.這是由如下動詞的開頭字母組成：permit,advise, practise,avoid,consider,mind,allow,keep,enjoy,suggest, finish,risk,imagine,escape,need,delay,stand(忍受).爲了容易記住,也可以編成順口溜：“允許完成練習,建議避免冒險,考慮延期逃跑,喜歡保持想象,需要反對忍受”.其相對應的動詞依次是：permit/allow,finish,practise;

advise/suggest,avoid,risk： consider, delay, escape/miss; enjoy/appreciate, keep, imagine;need/want/require,mind. can't help/can’t stand.

二、複合句

1、學生最容易混淆的是定語從句與同位語從句的區別.

例如：A、Thenews that our team has won the match is true. (同位語從句)

B、Thenews that he told us surprised everybody here. (定語從句)

關鍵的區別在於連接或關係代詞that：有意義的是定語,無意義的是同位.因爲引導定語從句的that在從句中作主語或 賓語,而引導同位語從句的that只起到連接詞的作用.

2、接着容易混淆的是引導定語從句的關係代詞that與which：that之前是不定(代詞)、序數(詞)、(形容詞)級：which之前是介詞短語與逗號(非限制性).

例如：A、Allthat we have to do is to practise every day.

B、Thefirst lesson that I learned will never be forgotten.

C、Ihave lost my pen,which I like very much.

D、Thehouse in front of which there is a garden is my home.

非謂語動詞中的易錯點

非謂語與其邏輯主語(即動作的執行者或承受者)之間有三種關係，如爲主謂關係，則用現在分詞或不定式的主動式;如爲被動關係則用過去分詞、現在分詞的被動(強調動作正在進行)或不定式的被動式(動作將進行);如既無主動也無被動關係則只能用狀語從句或獨立主格結構(即非謂語加上自己的邏輯主語)

Judging/considering/genrally?speaking/supposing?指說話者的動作，故只用主動式。如：?

Having?been?ill?in?bed?for?nearly?a?month?,?he?had?a?hard?time?passing?the?exam.?

解析：從這個句子可以看出，句詞的邏輯主語與句子的主語he一致，並且是主謂關係，所以用了現在的分詞作狀語，同時，分詞的動作明顯地發生在句子的謂語動詞動作之前，故採用了現代分詞的完成式。

In?order?to?improve?English?,?________.?

A.?Jenny’s?father?bought?her?a?lot?of?tapes.?

B.?Jenny’s?father?bought?a?lot?of?tapes?for?herself.?

C.?A?lot?of?tapes?were?bought?by?Jenny.?

D.?A?lot?of?tapes?were?bought?by?Jenny?father.?

解析：根據不定式短語我們可以推知，句子的邏輯主語應該是人而不是物，所以，應該排除CD，再就是應該是Jenny提高自己的英語，而不是她爸爸，故答案先B.?

———，we?decided?to?go?out?for?a?walk.?

A.?It?is?fine?B.?It?fine?

C.?Being?fine??fine?

解析：主句主語we與動詞短語be?fine之間既無主動關係與無被動關係，所以要加上自己的邏輯主語It，由於不存在主、被動關係，故不能選C項，而應該選D?項。?

————more?attention,?the?trees?could?have?grown?better.?A.?Given??ng?D.?Having?giving?

解析：give與主句的主語之間是被動關係，故選A.如爲主動關係則選C.?
