某日,外面陰云密布,雷雨交加...

CC貓看著窗外說(shuō),激動(dòng)地說(shuō): “It seems to rain.”

虎虎一聽,暗笑了一下,伸出手接了幾滴雨后,轉(zhuǎn)向CC貓說(shuō): “It seems to be raining.”

CC貓: ...

咳咳,我說(shuō)虎虎同志,你每次都這么揭穿CC貓偽學(xué)霸的事實(shí)真的好么?好了好了,咱不把CC貓當(dāng)炮灰使了,我們來(lái)看下偽學(xué)霸和真學(xué)霸所說(shuō)的兩句話:

It seems to rain. 看來(lái)要下雨了。

It seems to be raining. 看來(lái)正在下雨。

這兩句話的區(qū)別就在于時(shí)態(tài)不同,時(shí)態(tài)不同表達(dá)的意思就不同。那接下來(lái),我們一起來(lái)學(xué)習(xí)一下不定式的時(shí)態(tài):

1. 一般式

結(jié)構(gòu):to do / to be done

用法:動(dòng)詞不定式一般式所表示的動(dòng)作與謂語(yǔ)動(dòng)詞所表示的動(dòng)作同時(shí)發(fā)生或者發(fā)生在謂語(yǔ)動(dòng)詞之后。

David threatened to report his neighbor to the police if the damages were not paid.?

大衛(wèi)威脅說(shuō)如果鄰居不賠償損失,他就報(bào)警。(to report發(fā)生在threaten之后)

We often hear Yvonne play the piano in the sitting room.

我們經(jīng)常聽到伊馮在客廳彈鋼琴。(play和hear同時(shí)發(fā)生) 這里hear是感官動(dòng)詞,其后不定式省略了to.

2. 進(jìn)行式

結(jié)構(gòu):to be doing

用法:動(dòng)詞不定式進(jìn)行式表示動(dòng)作正在進(jìn)行,與謂語(yǔ)動(dòng)詞表示的動(dòng)作同時(shí)發(fā)生。

They seemed to be eating something they had cooked on the fire.?

他們似乎在吃著他們?cè)诨鹕现蟮氖澄铩#╯eemed和to be eating同時(shí)發(fā)生)

3. 完成式

結(jié)構(gòu):to have done / to have been done

用法:動(dòng)詞不定式完成式所表示的動(dòng)作在謂語(yǔ)動(dòng)詞表示的動(dòng)作之前發(fā)生。

The book is said to have been translated into many other languages.?

這本書據(jù)說(shuō)被譯成了多種其他語(yǔ)言。(to have been translated發(fā)生在is said之前)

4. 完成進(jìn)行式

結(jié)構(gòu):to have been doing

用法:動(dòng)詞不定式完成進(jìn)行式表示動(dòng)作是在謂語(yǔ)動(dòng)詞所表示的時(shí)間之前一直在進(jìn)行的動(dòng)作。

He appears to have been waiting for a long time.?

看來(lái)他已經(jīng)等了很久了。(to have been waiting這個(gè)動(dòng)作在appear之前一直在進(jìn)行)

教學(xué)完畢,其實(shí)如果大家對(duì)時(shí)態(tài)對(duì)句式熟悉的話,這些不定式的時(shí)態(tài)應(yīng)該也是沒(méi)問(wèn)題的,只要根據(jù)具體的意思選擇合適的結(jié)構(gòu)就行。相信大家一定和CC貓一樣恍然大悟了吧!
