1、非謂語動詞是高中三年乃至以后的英語學習中都非常重要的內(nèi)容,在高中階段性考試和重要考試中占較大分值的比重。
非謂語動詞是指分詞(包括現(xiàn)在分詞和過去分詞)、不定式、動名詞等三種形式,即:doing , done , to do , doing 。
當然它們有各自不同的變化形式,如:
現(xiàn)在分詞 doing : 有being done(被動式) ; having done (完成式); having been done (完成被動式)
不定式 to do : 有to be done (被動式); to have done (完成式); to be doing(進行式)
動名詞 doi
2、ng : 有having done(完成式); being done(被動式) ; having been done (完成被動式)
非謂語動詞的特點: 三種非謂語動詞都具有動詞的特征,雖然它們沒有人稱和數(shù)的變化,但是它們都能帶自己的狀語或有時跟賓語。具體來講:分詞在句子中可以做定語、表語、狀語或補足語等;動名詞在句子中可以做主語、賓語、表語、定語等;不定式在句子中可以做主語、賓語、表語、定語、補足語或狀語。
下面分別對三種非謂語動詞進行講解:
一、動詞不定式
先看幾個例句,判斷不定式在句中的成分。
1.To learn a foreign languageis difficult
3、.作主語
2. His wish isto be a driver. 作表語
3.Tom wantedto have a cup of beer.作賓語
4.The teacher told usto do morning exercises . 作賓語補足語
5.I have nothingto say.作定語
6.They wentto see their aunt. 目的狀語
7.It’s easyto see their aunt.作真正主語,it做形式主語
8.I don’t knowwhat to do next.帶有連接代詞的動詞不定式作賓語
9.I heard
4、themmake a noise.不帶to 的動詞不定式作賓語補足語
掌握動詞不定式應注意的幾個問題:
1.“to” 是不定式符號還是介詞,下列短語中的to 都是介詞。
agree to object to close to , come to , lead to , refer to ,
equal to , familiar to , point to , thank to , devote to , next
to , belong to , be used to , look forward to
2. 帶to 還是不帶to
I have no choice but
5、to give in
I cannot do anything but give in
I saw him enter the classroom .
但是: He was seen to enter the classroom .(被動語態(tài)中必須還原to)
3. 動詞不定式邏輯主語是由for 作為標記的。但是有時用of .
It’s necessary for you to study hard 。表物的特征
It’s foolish of him to do it . 表人的特點
4.后接不定式作賓語的動詞有:
want , hope , wish , like , b
6、egin , try , need , forget , agree , know , promise , teach , refuse , help , arrange , dare ,
decide , determine , fail , manage , offer , prepare , continue , ask , mean , choose , expect etc.
需要賓語補足語的動詞不能用動詞不定式直接做介詞的賓語,而要用it做形式賓語。例如:通常不說We think to obey the laws is important . 而說We think it imp
7、ortant to obey the laws .
5.不定式的省略。下列短語中,如果意義明確常常省略到to 。
want to , wish to ,hope to , like to , hate to , plan to , try to , love to , have to , ought to , need to , used to , be able to
6.不定式作定語,應注意兩種關系:
1)動賓關系:
He has a lot of meeting to attend .
Please lend me something to write with .
H
8、e is looking for a room to live
He is looking for a room to live in .
He has no money and no place to live ( in ) .
I think the best way to travel ( by ) is on foot .
There is no time to think ( about ) .
2)主謂關系:
She is always the last ( person) to speak at the meeting .
---I’m going to the p
9、ost office , forIhave a letter to post . ( 邏輯主語是I )
---Thank you. But I have no letters to be posted now (邏輯主語不是I )
7.不定式作狀語,可以有以下幾種意義:
1) 原因
He is luckyto get here on time.
這種結構中常用的形容詞有:
happy , glad , delighted , pleased , sorry , eager , anxious .
lucky , fortunate , proud , angry surprise
10、d , frightened ,
diappointed , ready , clever , foolish , worthy
2) 目的

3) 結果

能跟不帶to 的不定式作補足語的動詞有:
五看: see , look at,watch, observe
11、, notice
兩聽: hear , listen to
三使: let , have make,
