Question

much用在肯定句还是否定句？

Answer 1

much的用法很多，有很多词性。much做副词修饰动词

时，通常只用于否定句或疑问句中，一般不能用于肯定句中（除非前面有 very, too, so 等之类的修饰语）。
如：

正：She doesn't like him much. (用于否定句，故正确)

正：She doesn't much like him. (用于否定句，故正确)

正：Does she like him much? (用于疑问句，故正确)

正：Does she much like him? (用于疑问句，故正确)

正：She likes him very [too, so] much. (其前有修饰语，故正确)
