Question

this math problem is ____than that one

A so easy as B as difficult as C much difficult than D less easier than
句子中的than去掉，打错了

Answer 1

没有正确选项，C是打错吧，应该是much more diffictult 或 more difficult ,要不就是原句多了than
即：

this math problem is （C . much more difficult / more difficult ) than that one
或
this math problem is ( B as diffictult as ) that one.

加油！不明白再问！如果帮到你，请采纳，谢谢！

追问

没有打错，你认为B,D怎么样，选哪个

追答

原句中的THAN 没有，正确的答案就是B

追问

为什么不选D呢

追答

比较级前不能用less 修饰，故D错。

追问

那是不是，less 原级 than

追答

没错，但less +形容词/ 副词原形+ t han ' ……不如……‘

如This book is less interesting /difficult than that one .
=This book isn't as /so interesting/ difficult as that one .

这本书没有那本书那么有趣/难。

Answer 2

D，这道数学题没有那道简单
so+形容词原级+as，一般用于否定疑问句
as+形容词原级+as
much+形容词比较级+than
less+形容词比较级+than

追问

正确答案为B若知道原因，请告诉我

追答

那就是你题目打错了嘛，多打了一个than

追问

对你的回答更正一下，less 原级 than，而不是加比较级

追答

噢 对 记岔了
