so...as和as...as有什么区别

米有……

在意思上它们是一样的,只是在用法上有一点区别。
一般在否定句中多用so...as,而在肯定句中多用as...as.
eg.
1.The box is as big as that one.
2.This shirt is not so tide as that one.

好像前者只能用于否定?
后者既能用于否定也能用于肯定~

前者一般用在否定句

在意思上它们是不一样的,在否定句中既可以用not as ...as...也可以用not so...as,而在肯定句中只能用as...as...
He is as clever as you.(He is not as/so clever as you.)
但下面的句子要特别注意:
1) I'll come back as soon as possible.
2) The clouds are as white as snow.
3) He is so strong as to lift a big stone.(so...as to do:那么......以至......)

so...as只用于否定句中,as...as用于一般句或否定句中

so...as用于否定句
