1. so/such...that...的倒装为含有so/such的主句部分倒装,而that引导的结果状语从句不用倒装.
2. 主句部分倒装的规则是：把主句含有so/such的部分提前至句首,剩余部分如同变一般疑问句一样,再把be动词/助动词/情态动词提前,具体结构如下：
1）so + 形容词/副词 + 主句剩余部分的部分倒装 + that...
如：He ran so fast that I couldn't catch up with him.
倒装为：So fast did he run that I couldn't catch up with him.
He is so tall that he sits in the back of the classroom.
倒装为：So tall is he that he sits in the back of the classroom.
2）so + 形容词 + a/an + 可数名词单数 + 主句剩余部分的部分倒装 + that...
如：He is so clever a boy that his parents are proud of him.
倒装为：So clever a boy is he that his parents are proud of him.
3）such + a/an + 形容词 + 可数名词单数 + 主句剩余部分的部分倒装 + that...
如：He is such a clever boy that his parents are proud of him.
倒装为：Such a clever boy is he that his parents are proud of him.
4）so/such + 形容词 + 可数名词复数/不可数名词 + 主句剩余部分的部分倒装 + that...
如：There were so many students in the room that I couldn't enter it.
倒装为：So many students were there in the room that I couldn't enter it.
We had such little money that we couldn't afford this car.
倒装为：Such little money did we have that we couldn't afford this car.
3. 此等句型中的such/so的使用类似于平常我们讲的such/so的区别.
