初三上冊英語知識點歸納

to+動詞原形

(1)作主語

動詞不定式作主語時,句子的謂語動詞常用單數(shù),其位置有以下兩種: (1)把不定式置于句首。

如:To get there by bike will take us half an hour.

(2)用it作形式主語,把真正的主語不定式置于句后,常用于下列句式中。

如:

It+be+名詞+to do It's our duty to take good care of the old.

It takes sb+some time+to do How long did it take you to finish the work?

It+be+形容詞+for sb+to do It is difficult for us to finish writing the composition in a quarter of an hour.

It+be+形容詞+of sb+to do It is stupid of you to write down everything (that) the teacher says.

It seems(appears)+形容詞+to do It seemed impossible to save money.

在句型中,常用表示客觀情況的形容詞,如:difficult,easy,hard,important,impossible,necessary 等;

在句型中,常用careless,clever,good,foolish,honest,kind,lazy,nice,right,silly,stupid,wise等 表示贊揚或批評的詞。

在不定式前的sb,可看作其邏輯主語。這一句式有時相當于Sb is+形容詞+to do句式 ,如:It's kind of you to help me with my English.=You are kind to helpme with my English.

(3)舉例

(1) It's easy (for me) to do that.我做這事太容易了

easy, difficult, hard, important, possible, impossible, comfortable, necessary, better;

the first, the next, the last, the best, too much, too little, not enough

1、It's so nice to hear your voice.

聽到你的聲音真高興。

2、It's necessary for you to lock the car when you do not use it.

當你不用車的時候,鎖車是有必要的。

(2) It's very kind of him to help us. 他幫助我們,他真好。

Kind, nice, stupid, rude, clever, foolish, thoughtful, thoughtless, brave, considerate(考慮周到的), silly, selfish(自私的)

例句:

1、It was silly of us to believe him. 我們真愚蠢,竟然相信了他。

2、It seemed selfish of him not to give them anything. 他不給他們任何東西,這顯得太自私了。

注意:

(1) 其他系動詞如,look,appear等也可用于此句型

(2) 不定式作為句子成分時,動詞用單數(shù)形式。

(3) 當不定式作主語的句子中又有一個不定式作表語時,不能用It is… to…的句型

(對)To see is to believe. 眼見為實。

(錯)It is to believe to see.

初三上冊英語知識點梳理

動詞不定式作賓語

后面能接不定式作賓語的動詞有:agree, ask, choose, decide, forget, hope, learn, want, wish, would like等。

1、We hope to get there before dark. 我們希望天黑以前到那兒。

2、The man decided to do it herself. 那個男人決定自己做那件事。

動詞不定式作賓語的注意事項(2點)

1. 有些動詞既可跟不定式作賓語,也可跟動名詞作賓語,但含義不同:

remember to do 記住要做某事

remember doing 記得曾經做過某事

forget to do忘記要做某事

forget doing 忘記曾經做過某事

stop to do 停下來去做某事

stop doing 停止做某事

go on to do 繼續(xù)做另一件事

go on doing 繼續(xù)做原來在做的事

2. 不定式作賓語時,如帶有賓語補足語,則要把不定式放到后面,用it作形式賓語,構成“主語+動詞+it+賓補(形容詞、名詞)+不定式”結構。

如:He found it very difficult to get to sleep.他發(fā)現(xiàn)很難入睡。

動詞不定式作賓語補足語

1. 后面能接to不定式作賓語補足語的動詞有:ask, order, teach, tell, want, wish, help等。

The teacher told us to do Exercise 1. 老師要我們做練習一。

I want both of you to go. 我要你們倆去。

We helped her (to) repair her bike. 我們幫助她修理自行車。

2. 使役動詞let, have, make及感官動詞see, watch, notice, hear, feel等要以不帶to的不定式作賓補。

Let’s have a rest. 我們休息一會吧。

I saw him come in. 我看見他進來了。

感官動詞后既可跟不帶to的不定式作賓補,也可跟v-ing作賓補,前者表示動作的全部過程已結束;后者表示動作正在進行。

I saw him come downstairs.我看見他下了樓。(說明他下樓了這件事)

I saw him coming downstairs.我看見他在下樓。(說明他下樓時的情景)

初三上冊英語知識點提綱

動詞不定式作定語

不定式作定語一般放在所修飾的詞的后面。

I need something to eat.

Do you have something to read?

Tom was so excited that he had no word to say.

He is really a fool only to eat.

The man to stand here just now is our English teacher.

The doctor had no way to save the patient.

注意:

(1)作定語的不定式是由及物動詞組成,被修飾的名詞或代詞與不定式之間存在方位或方式關系需要有介詞。

I am looking for a room to live in. 我正在找一間住房。(方位關系)

We have many things to do experiments with.

我們有許多做實驗的東西(方式關系)

(2)作定語的不定式是由“be + adj + prep”構成的動詞短語。

Here there isn’t any book for me to be interested in.

We have done many things to proud of. 我們做了許多引以自豪的事。

初三上冊英語知識點總結

動詞不定式作主語

To give is better than to receive.

To reach there on foot is impossible.

動詞不定式作主語時,可以用it 代替,把實際主語不定式放在后面。

It’s better to give than to receive.

It’s impossible to reach there on foot.

It’s + adj + for sb. to do sth.

It’s not difficult for me to study English well.

It’s easy for him to work out this math problem.

在這個句型中,如果形容詞與不定式的邏輯主語關系密切,并且形容詞用來說明邏輯主語的性質、品質、特點等,由of引出邏輯主語。這類形容詞主要有nice, kind, good, wrong, right等。
