Question

this problem is __ that one. A.as difficult as B.less easier than C.so easy

谢谢哦 请说明原因

Answer 1

A.
B选项easier 已经是比较级，不能加less。C选项so easy后面不能叫名词。
这道题两个关键词，this, that，所以应该是比较两者，B选项已经错了，C选项一是读不通，而是没有任何比较。A选项X is as...as Y表达X和Y一样...，所以选A

追问

如果c项是so easy as能不能选择 谢谢！！！

追答

不能，除非前面是否定句，这个搭配是not so...as， 就是说，以下说法是正确的：
This problem is as difficult as that one
This problem is not SO easy as that one.
This problem is not AS easy as that one.

Answer 2

so easy as 也不可以，它放在否定句当中，相当于 肯定句中的as easy as
