某日,外面陰云密布,雷雨交加...

CC貓看著窗外說,激動地說: “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: “It seems to be raining.”

CC貓: ...

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

It seems to rain. 看來要下雨了。

It seems to be raining. 看來正在下雨。

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

1. 一般式

結(jié)構(gòu):to do / to be done

用法:動詞不定式一般式所表示的動作與謂語動詞所表示的動作同時發(fā)生或者發(fā)生在謂語動詞之后。

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

大衛(wèi)威脅說如果鄰居不賠償損失,他就報警。(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同時發(fā)生) 這里hear是感官動詞,其后不定式省略了to.

2. 進行式

結(jié)構(gòu):to be doing

用法:動詞不定式進行式表示動作正在進行,與謂語動詞表示的動作同時發(fā)生。

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

他們似乎在吃著他們在火上煮的食物。(seemed和to be eating同時發(fā)生)

3. 完成式

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

用法:動詞不定式完成式所表示的動作在謂語動詞表示的動作之前發(fā)生。

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

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

4. 完成進行式

結(jié)構(gòu):to have been doing

用法:動詞不定式完成進行式表示動作是在謂語動詞所表示的時間之前一直在進行的動作。

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

看來他已經(jīng)等了很久了。(to have been waiting這個動作在appear之前一直在進行)

教學(xué)完畢,其實如果大家對時態(tài)對句式熟悉的話,這些不定式的時態(tài)應(yīng)該也是沒問題的,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!
