不定式
1. 作主語(yǔ)：The cat said, “To take roller coaster is terrible”.
不定式短語(yǔ)作主語(yǔ)時(shí)，可以直接放在句首，在疑問(wèn)句和感嘆句中，往往放在謂語(yǔ)之后，而用先行代詞it作形式主語(yǔ)。
How long did it take you to finish the task
不定式作主語(yǔ)常見(jiàn)句型：
a) It is + adj. (easy, important, difficult…) + 不定式
b) It is + n. (a pity, a pleasure, one’s duty, a shame) + 不定式
It’s my duty ____________________________. (教你們學(xué)好英語(yǔ))
c) It takes/needs/requires + some time (hours, months, days, patience…) + 不定式
It requires patience ________________________________. （做好這項(xiàng)工作）
2. 作表語(yǔ)：當(dāng)句子的主語(yǔ)是aim, idea, policy, question, suggestion, wish, task, duty, job, purpose等或者主語(yǔ)是what引導(dǎo)的名詞性從句時(shí)，后面可以用不定式做表語(yǔ)，用以說(shuō)明主語(yǔ)所包含內(nèi)容。
Our most important task now is _____________________ . (制定計(jì)劃)
注：作表語(yǔ)的不定式都帶to，但當(dāng)主語(yǔ)部分有實(shí)義動(dòng)詞do時(shí)，to可以省略。
The only thing we can do now is _________________ . (等等看)
3.作賓語(yǔ)
The cat said “Remember ________________next time!”.(別遲到)
a) 可以直接用不定式作賓語(yǔ)的動(dòng)詞很多，常見(jiàn)的有：agree, afford, tend, ask, decide, determine, expect, fail, hope, learn, intend, manage, offer, plan, promise, refuse, want, wish等。
當(dāng)不定式短語(yǔ)比賓補(bǔ)長(zhǎng)時(shí)，往往將不定式放到賓補(bǔ)后，而用先行代詞it作形式賓語(yǔ)，常用動(dòng)詞有feel, think, find, believe, consider, make等。
The cat felt it _________________________________ . (躺在草地上很舒服)
b) 不定式一般不作介詞的賓語(yǔ)，只有少數(shù)介詞如but, except等后面可以跟不定式作賓語(yǔ)。一般情況下作介詞賓語(yǔ)的不定式都帶to，如果but或except所在句子里的謂語(yǔ)動(dòng)詞都是實(shí)義動(dòng)詞do, does, did時(shí)，通常省略to。
We have no choice ______________________. (只好等)
We can do nothing __________________ . (只好等)
4. 賓語(yǔ)補(bǔ)足語(yǔ)
a) 通常作賓語(yǔ)補(bǔ)語(yǔ)的不定式要帶to，常用于以下動(dòng)詞之后：ask, tell, advise, allow, enable, expect, force, get, like, order, teach, want, invite, wish, beg等
You should get them___________________ .(立刻開(kāi)始工作)
但在謂語(yǔ)動(dòng)詞believe, find, think, feel, consider, suppose, imagine, prove等后面跟to be…作賓補(bǔ)，不跟to do…
They believe _____________________________ . (他誠(chéng)實(shí))
b) 使役動(dòng)詞let, have, make等，感官動(dòng)詞hear, feel, see, watch, notice等接不帶to 的動(dòng)詞不定式，如用在被動(dòng)語(yǔ)態(tài)則加上to
Don’t let the children ________________ . (麻煩你)
I heard someone . (敲門(mén))
He was made early by his father. (上床睡覺(jué))
5. 作定語(yǔ)：
①能帶不定式作賓語(yǔ)的動(dòng)詞，其同源名詞可以帶不定式作定語(yǔ)。常見(jiàn)的有attempt, decision, promise, plan等
He hasn’t kept his promise ____________________________. (經(jīng)常給他父親寫(xiě)信)
②常與不定式搭配的形容詞，其同源名詞一般可以用不定式作定語(yǔ)。常見(jiàn)的有ability, determination, anxiety, eagerness等
His eagerness _________________________________was quite clear.(渴望早點(diǎn)完成作業(yè))
③序數(shù)詞形容詞最高級(jí)或被only, last, next等修飾的名詞可以用不定式作定語(yǔ)：
She was the only person ______________after the earthquake. (幸存)
不定式在作定語(yǔ)時(shí)，有時(shí)與被修飾的名詞有意義上的主謂關(guān)系、同位關(guān)系、動(dòng)賓關(guān)系，如果該不定式是不及物動(dòng)詞，它后面需要加上適當(dāng)介詞。
He’s always the first to come and the last to leave. 主謂關(guān)系
I’ve no time to listen to your excuse. 同位關(guān)系
She has a meeting to attend. （動(dòng)賓關(guān)系=attend a meeting）
There’s nothing to worry about. (動(dòng)賓關(guān)系=worry about nothing)
6. 作狀語(yǔ)
①to…, in order to …, so as to …(不能放在句首)作目的狀語(yǔ)

A. in order to have received B. in order to receive C. so as to be received D. so as to be receiving
②在so…as to, such….as to, only to …結(jié)構(gòu)中不定式作結(jié)果狀語(yǔ)，其中only to…用于表示意想不到的結(jié)果。

③enough to, too…to結(jié)構(gòu)

①不定式的進(jìn)行式由to be + V-ing構(gòu)成，用來(lái)表示謂語(yǔ)動(dòng)詞動(dòng)作發(fā)生時(shí)，不定式的動(dòng)作正在進(jìn)行。
Some students pretended ________________________when the teacher came in.. (在讀英語(yǔ))
②不定式完成式由to have + V-ed構(gòu)成，用來(lái)表示動(dòng)作發(fā)生在謂語(yǔ)動(dòng)作之前。
--- Is Bob still performing?
--- I’m afraid not. He is said _______ the stage already as he has become an official.
A. to have left B. to leave C. to have been D. to be left
③不定式的被動(dòng)式分為一般式被動(dòng)to be V-ed和完成式被動(dòng)to have been V-ed。當(dāng)不定式的邏輯主語(yǔ)是不定式所表示的動(dòng)作的承受者時(shí)，不定式要用被動(dòng)語(yǔ)態(tài)。

動(dòng)名詞
1. 動(dòng)名詞的句法功能：動(dòng)名詞由動(dòng)詞加ing構(gòu)成，與現(xiàn)在分詞的形式相同。動(dòng)名詞主要起名詞作用，在句中擔(dān)任主語(yǔ)、表語(yǔ)、賓語(yǔ)和定語(yǔ)。
①作主語(yǔ) 可以直接放在句首，也可以用先行代詞it作為形式主語(yǔ)，而把動(dòng)名詞后置。
Seeing is believing. (眼見(jiàn)為實(shí))
__________ is easier than _________.(說(shuō)起來(lái)容易,做起來(lái)難)
_________________is a good hobby.(集郵)(單個(gè)動(dòng)名詞短語(yǔ)作主語(yǔ)時(shí)，動(dòng)詞用單數(shù))
動(dòng)名詞作主語(yǔ)還有以下兩個(gè)習(xí)慣表答法：
It is no use (good) + 動(dòng)名詞：做某事沒(méi)有用
It’s no use___________________________ (覆水難收)
There is no + 動(dòng)名詞 (= It is impossible to do sth.)
②作表語(yǔ) 通常是說(shuō)明主語(yǔ)的內(nèi)容，注意它與謂語(yǔ)動(dòng)詞進(jìn)行時(shí)的區(qū)別
His hobby is collecting stamps. (此句為SVC結(jié)構(gòu)) 可改為：Collecting stamps is his hobby.
He is collecting stamps. (is collecting是謂語(yǔ)動(dòng)詞進(jìn)行時(shí)，此句為SVO結(jié)構(gòu))
不能改為：Collecting stamps is he.
③作賓語(yǔ)
A. 作及物動(dòng)詞 的賓語(yǔ)(enjoy, mind, finish, appreciate, avoid, consider, delay, escape, pratise, suggest, keep(on), miss)
He got well-prepared for the job interview, for he couldn’t risk _____ the good opportunity.
A. to lose B. losing C. to be lost D. being lost
有些動(dòng)詞（attempt, begin, continue, hate, like, love）后面既可以接不定式作賓語(yǔ)，也可以接動(dòng)名詞作賓語(yǔ)，意義差別不大。通常認(rèn)為用動(dòng)名詞泛指一般的傾向性，用不定式則表示特定或具體某一種動(dòng)作。
I like swimming but I don’t like to swim in winter.
動(dòng)詞prefer后面接不定式作賓語(yǔ)時(shí)，句子結(jié)構(gòu)與按動(dòng)名詞作賓語(yǔ)是不一樣。
I prefer to drive rather than be driven.
I prefer driving to riding.
有些動(dòng)詞，如forget, remember, regret等，后面接動(dòng)名詞表示的動(dòng)作先于謂語(yǔ)動(dòng)詞動(dòng)作，不定式表示的動(dòng)作后于謂語(yǔ)動(dòng)詞。
When asked by police, he said that he remembered _____ at he party, but not ______.
A. to arrive, leaving B. to arrive, to leave C. arriving, leaving D. arriving, to leave
動(dòng)詞+it（形式賓語(yǔ)）+賓補(bǔ)+動(dòng)名詞（真正賓語(yǔ)）
I think it no use_________________________ .(告訴她真相)
We think it no good ____________________ (浪費(fèi)時(shí)間打游戲)
B. 作介詞的賓語(yǔ)
Everybody in the village likes Jack because he is good at telling and ______ jokes.
A. turning up B. putting up C. making up D. showing up
④作定語(yǔ)
動(dòng)名詞可作前置定語(yǔ)，表示所修飾的詞的用途或目的，可用for改寫(xiě)；而現(xiàn)在分詞作定語(yǔ)時(shí)，可用定語(yǔ)從句改寫(xiě)。
a sleeping car=a car for sleeping a sleeping child= a child who is sleeping
⑤作同位語(yǔ)
That’s the queen’s full-time job, __________________.這就是蟻后的專(zhuān)職工作——產(chǎn)卵。
2．動(dòng)名詞的邏輯主語(yǔ)
①人稱(chēng)代詞做邏輯主語(yǔ)時(shí)應(yīng)用所有格，即形容詞性物主代詞。
Do you minding______________________?(我抽煙)
②邏輯主語(yǔ)是不定代詞或指示代詞時(shí)，很少用所有格，而用普通格。
He was awakened by someone _____________________.(敲門(mén))
③邏輯主語(yǔ)是名詞時(shí)，用所有格，但是如果名詞為無(wú)生命物體時(shí)，則用普通格。
___________________________ made Tom angry. (瑪麗大笑)
There is no ___________________________________.(工廠盈利希望)
④在口語(yǔ)中，動(dòng)名詞如果不在句首，可以用名詞普通格或人稱(chēng)代詞賓格作邏輯主語(yǔ)。
I really can’t understand _____ her like that.
A. you treat B. you to treat C. why treat D. you treating
3. 動(dòng)名詞的完成式、一般式被動(dòng)和完成式被動(dòng)。新課標(biāo)第一網(wǎng)
