so...that...如此……以致于……
...so that...以便于,為了
“so...that...”句型的意思是“如此/這么……以致于……”,常引導(dǎo)結(jié)果狀語從句,但“so...that...”是個(gè)愛“變臉”句型,你一不留意就會(huì)出錯(cuò).“so...that...”句型及其轉(zhuǎn)換也是中考的熱點(diǎn),現(xiàn)將其用法總結(jié)歸納如下,讓我們一起來看看它是怎樣變的吧.
一、 so... that...句型中的so是副詞,常常用來修飾形容詞或副詞,常用句型為：主語+謂語+so+adj. / adv. + that從句.例如：
1. he is so young that she can't look after herself.
2. The boy ran so fast that I couldn't catch him.
3. He was so angry that he couldn't say a word.
二、 在“such... that...”句型中,such修飾名詞,意思也是“如此……以致于……”但當(dāng)名詞前有many、much、(a) few、(a) little等詞修飾時(shí),句子中要用“so...that...”而不能用“such...that...”.例如：
1. He has so much money that he can buy what he wanted.
2. I've had so many falls that I have pains here and there.
3. There is little water in the glass that I can't drink any more.
三、 so與that也可連起來寫,即變成：... so that ...(以便 / 為了……),引導(dǎo)目的狀語從句.例如：
1. I got up early so that I could catch the early bus.
2. Please open the window so that we can breathe fresh air.
3. You must go now so that you won't be late.
四、以“so...that”引導(dǎo)的結(jié)果狀語從句可以轉(zhuǎn)換成不定式的簡單句,即可轉(zhuǎn)換為“...enough to...”或“...too...to”句型,但這種轉(zhuǎn)換必須符合下列條件：
1. 當(dāng)主句和從句的主語一致,且that從句是肯定句時(shí),可用“enough to do sth.”來轉(zhuǎn)換.例如：
The man is so strong that he can lift the heavy box.→
The man is strong enough to lift the heavy box.
He was so clever that he can understand what I siad. →
He was clever enough to understand what I siad.
2. 當(dāng)主句和從句的主語不一致,且that從句是肯定句時(shí),可以用“enough for sb. to do sth.”來替換,但須注意不定式的賓語要省略.例如：
The question is so easy that I can work it out. →
The question is easy enough for me to work out.
The box is so light that he can carry it. →
The box is light enough for him to carry.
3. 當(dāng)主句和從句的主語一致,且that從句是否定句時(shí),可以用“too...to”來替換.例如：
The girl is so young that she can't dress herself. →
The girl is too young to dress herself.
I was so tired that I couldn't go on with the work. →
I was too tired to go on with the work.
4. 當(dāng)主句和從句的主語不一致,且that從句是否定時(shí),如果要用“too...to...”替換“so...that...”,則用介詞for引出動(dòng)詞不定式的邏輯主語,可以用“too...for sb. to do sth.”來替換,注意不定式的賓語要省略.
The bag is so heavy that she can't move it. →
The bag is too heavy for her to move.
It is so hot that we can't sleep. →
It is too hot for us to sleep.
