为什么用“so……that”不用“such……that”

Question

为什么用“so……that”不用“such……that”
they are (so) busy studying (that) they can't play football with us.
详细点 多举些例子 类似的如何判断
为什么这个是 so+adj.+v-ing+that
这个so应该是修饰studying的，studying是动名词为什么不用such
如何判断是修饰busy还是studying的，有类似的吗？

Answer 1

这个句子有很多从结构
总体上是结果状语从句 THAT是引导连词
主句中用“BE BUSY DOING STH"的句型这里的SO修饰的是BUSY 因此不能用SUCH 而这里"SO THAT"也是初中常见句型
这个句子的重点是要弄清句子成分 先研究整体 在研究主句 从句的具体句型
例句：
It was so cold that we did not want to go out．
It was such a cold day that we did notwant to go out．
天太冷了，我们都不想出去。

The play was so interesting that I went to see it several times．
This was such an interesting play that I went to see it several times．
这个话剧十分有趣，所以我去看过好几次。
你这个句子让人迷糊就在于他在SO THAT 句型中又加入了 BE BUSY DOING 这里PLAYING是和BUSY一起的 还是应一步一步分析 先看整体 多做些题就会判断了

Answer 2

be busy doing sth 是一个固定搭配“忙于做某事”so+形容词/副词+that... ; such+形容词+不可数名词/可数名词复数 +that ..； such+a/an +形容词+可数名词单数+ that...,e.g
1) It is such an interesting book that I want to read it again.
2) Thse are such interesting books that everyone likes to read it.
3) It is such bad weather that I have to stay at home.本回答被提问者采纳

Answer 3

"so...that..."是"因为...所以..."

"such...that..."是指程度。

例：
they are (so) busy studying (that) they can't play football with us.

他们太忙了，所以不能和我们玩橄榄球。

she has such long fingernails that can frighten people
who saw them.

她的指甲长到了吓人的地步。

Answer 4

so后面一般接形容词，就像你说的这个句子
但是such后一般接名词，比如she is such a beautiful girl that …

Answer 5

上列中so直接修饰的是busy而不是studying，所以不用such
