一樣,先來(lái)看看不定式的結(jié)構(gòu)。

1. to be done

2. 不定式還有完成式的被動(dòng)式,結(jié)構(gòu)為to have been done

3. 在There be句型中: 不定式用作定語(yǔ)修飾主語(yǔ)而表示被動(dòng)意義時(shí),一般情況下,既可以用主動(dòng)形式,也可以用被動(dòng)形式。

1、好了,總的結(jié)構(gòu)句式不外乎以上三種。但是在實(shí)際運(yùn)用中,不定式到底用主動(dòng)形式還是被動(dòng)形式,往往取決于句子的意思,即意思上為主動(dòng)就用主動(dòng)形式,意思上為被動(dòng)就用被動(dòng)形式:例如:

Did it need to be done this morning?

這事今天早上久做完嗎?

She can’t afford to buy a house of her own。

她現(xiàn)在還買不起自己的房子。

Whether you are right? or?not Is going to be tested by time。

你是否正確,需要時(shí)間來(lái)判定。

2、不定式的完成被動(dòng)式表示發(fā)生在謂語(yǔ)動(dòng)作之前的被動(dòng)動(dòng)作:

I’m honored to have been given the chance to stand here and let my voice heard by all

of you.

我非常榮幸能夠站在這里演講。

It’s said to have been dismantled 20 years ago

據(jù)說(shuō)這在20年前就被拆除了。

She asked to be sent to the USA for further study。

3、there be 句型中的不定式被動(dòng)語(yǔ)態(tài)

There were so many passengers need to be transferred。

很多滯留的旅客需要被轉(zhuǎn)移。

There was business to be taken care of.
