【重點(diǎn)語法】
動(dòng)詞不定式做目的狀語時(shí)的用法
To cut down air pollution, we should take the bus or subway instead of driving. 為了減少空氣污染,我們應(yīng)當(dāng)乘坐公汽或地鐵而不是開車。
本句中To cut down air pollution是動(dòng)詞不定式作目的狀語。
1. 不定
9、式和不定式短語作目的狀語
不定式和不定式短語作目的狀語,主要用來修飾動(dòng)詞,表示某一動(dòng)作或狀態(tài)的目的。為了使目的意義更加清楚或表示強(qiáng)調(diào)意義時(shí),還可以在前面加 in order to 或 so as to。
例如:I've written it down in order not to forget.
He shouted and waved so as to be noticed.
在句子中作謂語動(dòng)詞的狀語的不定式或不定式短語,表示的是主語的目的,因此,其邏輯主語通常是句子的主語。比較:
To draw maps properly, you need a special pen
10、.(正)
To draw maps properly, a special pen is needed.(誤)
由 in order to 引導(dǎo)的目的狀語,既可以置于句尾,也可以置于句首,而由 so as to 引導(dǎo)的目的狀語,只能置于句尾,而不能置于句首。比較:
They started early in order to get there in time.(正)
In order to get there in time, they started early.(正)
They started early so as to get there in time.(正)
So
11、 as to get there in time, they started early.(誤)
2. 不定式的復(fù)合結(jié)構(gòu)作目的狀語
當(dāng)不定式或不定式短語有自己的執(zhí)行者時(shí),要用不定式的復(fù)合結(jié)構(gòu)(即在不定式或不定式短語之前加 for + 名詞或賓格代詞)作狀語。例如:
He opened the door for the children to come in.
She fetched several bottles which she placed on the counter for Harry to inspect.
3. 目的狀語從句與不定式的轉(zhuǎn)換
英語中的目的狀語從句
12、,還可以變?yōu)椴欢ㄊ交虿欢ㄊ蕉陶Z作狀語,從而使句子在結(jié)構(gòu)上得以簡化??煞譃閮煞N情況:
(1)當(dāng)目的狀語從句中的主語與主句中的主語相同時(shí),可以直接簡化為不定式或不定式短語作狀語。例如:
We'll start early in order that/so that we may arrive in time.
We'll start early in order to/so as to arrive in time.
(2)當(dāng)目的狀語從句中的主語與主句中的主語不相同時(shí),要用動(dòng)詞不定式的復(fù)合結(jié)構(gòu)作狀語。例如:
I came early in order that you might read my report before the meeting.
I came early (in order) for you to read my report before the meeting.
