so...that...如此……以致于……
...so that...以便于,为了
“so...that...”句型的意思是“如此/这么……以致于……”,常引导结果状语从句
一、 so...that...句型中的so是副词,常常用来修饰形容词或副词,常用句型为：主语+谓语+so+adj./ adv.+ that从句.例如：
二、 在“such...that...”句型中,such修饰名词,意思也是“如此……以致于……”但当名词前有many、much、(a) few、(a) little等词修饰时,句子中要用“so...that...”而不能用“such...that...”.
三、 so与that也可连起来写,即变成：...so that ...(以便 / 为了……),引导目的状语从句.例 1.Please open the window so that we can breathe fresh air.
四、以“so...that”引导的结果状语从句可以转换成不定式的简单句,即可转换为“...enough to...”或“...too...to”句型,但这种转换必须符合下列条件：
1.当主句和从句的主语一致,且that从句是肯定句时,可用“enough to do sth.”来转换.例如：
The man is so strong that he can lift the heavy box.→
The man is strong enough to lift the heavy box.
2.当主句和从句的主语不一致,且that从句是肯定句时,可以用“enough for sb.to do sth.”来替换,但须注意不定式的宾语要省略.例如：
The question is so easy that I can work it out.→
The question is easy enough for me to work out.
3.当主句和从句的主语一致,且that从句是否定句时,可以用“too...to”来替换.例如：
The girl is so young that she can't dress herself.→
The girl is too young to dress herself.
4.当主句和从句的主语不一致,且that从句是否定时,如果要用“too...to...”替换“so...that...”,则用介词for引出动词不定式的逻辑主语,可以用“too...for sb.to do sth.”来替换,注意不定式的宾语要省略.
The bag is so heavy that she can't move it.→
The bag is too heavy for her to move.
