1、不定式做表語(yǔ)常表示謂語(yǔ)動(dòng)詞所表示動(dòng)作之后發(fā)生的動(dòng)作。不定式一般緊跟在系動(dòng)詞如: be, seem, remain, appear等后面, 用來(lái)說(shuō)明主語(yǔ)的內(nèi)容。這類(lèi)結(jié)構(gòu)中的主語(yǔ)一般為名詞，如：idea, purpose, hope, plan, intention, wish, dream, etc.

The task of this class is practising the idioms. （現(xiàn)在分詞做表語(yǔ)）

With the help of the teacher, the students are practising the idioms. （現(xiàn)在進(jìn)行時(shí)）

過(guò)去分詞作表語(yǔ)表示主語(yǔ)所處的被動(dòng)狀態(tài)或完成某動(dòng)作的狀態(tài)。而被動(dòng)語(yǔ)態(tài)表示主語(yǔ)所承受的動(dòng)作。

下列句子慣用不定式主動(dòng)語(yǔ)態(tài).

Eg.) The house is to let/to be let. 這房子待出租。

四、不定式與分詞在句中做賓語(yǔ)補(bǔ)足語(yǔ)：

1、以下動(dòng)詞后跟不定式做賓語(yǔ)補(bǔ)足語(yǔ)：

動(dòng)詞/動(dòng)詞詞組+賓語(yǔ)+to不定式:

常見(jiàn)動(dòng)詞: want, wish, ask, tell, order, beg, allow, permit, help, advise, persuade, cause, force, warn, invite, urge, encourage, prepare, call on, would like, wait for, etc.

比較: I saw him crossing the road. He was seen _____the road.

2、動(dòng)名詞與現(xiàn)在分詞做定語(yǔ)的區(qū)別：

動(dòng)名詞做定語(yǔ)說(shuō)明所修飾名詞的用途；現(xiàn)在分詞做定語(yǔ)，表示所修飾名詞進(jìn)行的動(dòng)作。

a walking stick 拐杖（動(dòng)名詞， a stick for walking）

a sleeping car 臥鋪車(chē)廂（動(dòng)名詞， a car for sleeping）

the rising sun 正在升起的太陽(yáng)（現(xiàn)在分詞）

3、現(xiàn)在分詞與過(guò)去分詞做定語(yǔ)的區(qū)別：過(guò)去分詞做定語(yǔ)表示完成或被動(dòng)的動(dòng)作，現(xiàn)在分詞做定語(yǔ)表示主動(dòng)或進(jìn)行的動(dòng)作。

動(dòng)名詞的復(fù)合結(jié)構(gòu):

① 物主代詞或名詞所有格+ 動(dòng)名詞(作主語(yǔ)、賓語(yǔ)、表語(yǔ))

② 代詞賓格或名詞普通格+ 動(dòng)名詞(作賓語(yǔ)、表語(yǔ))

The news of the new hotel catching fire shocked everyone.= The news that the new hotel caught fire shocked everyone.

The noises of the boxes being opened and closed could be heard.

存在句的非限定形式

存在句的非限定形式是there to和there being結(jié)構(gòu)。這兩種結(jié)構(gòu)在用法上有相同點(diǎn)。為便于比較，我們把它們放在一起介紹。

1） 作介詞補(bǔ)足成分

兩種結(jié)構(gòu)都可作介詞補(bǔ)足成分。如果介詞是for，便只能用there to be結(jié)構(gòu)。

Eg.) It is too early for there to be anyone around here.

It is important for there to be a fire escape.

也能用在不及物動(dòng)詞+for之后:

They planned for there to be another meeting.

如果介詞不是for, 則要用 there being結(jié)構(gòu)。

Eg.) John was relying on there being another opportunity.

2） 作賓語(yǔ)

作賓語(yǔ)時(shí), 通常用there to be結(jié)構(gòu)。

Eg.) Members like there to be plenty of choice.

能這樣用的及物動(dòng)詞為數(shù)有限,常見(jiàn)的有expect, mean, intend, want, like, prefer, hate等。

3） 作主語(yǔ)和狀語(yǔ)

there being結(jié)構(gòu)還能用作主語(yǔ)和狀語(yǔ)。

Eg.) There being a bus stop so near the house is a great advantage.

There having been no rain, the ground was dry.

存在句的限定形式與非限定形式之間可以相互轉(zhuǎn)換。

For there to be so few people in the streets was unusual.

(=It was unusual for there to be so few people in the streets.)

有時(shí)限定形式與非限定形式還可以結(jié)合使用。

Eg.) It is said that there are troops on the frontier. =There are said to be troops on the frontier.

關(guān)系代詞的省略:

1. This is the fastest train there is to Beijing.

2. He asks for the latest book there is on the shelf.

3. ---- What did the football player you were talking to want?

---- He would like to read or listen to an account of everything there is going on in the world.
