The patient has tried quite a few kinds of medicine,but ______ had any effect on his disease.A.none B.nothing C.neither D.no one

问题描述:

The patient has tried quite a few kinds of medicine,but ______ had any effect on his disease.
A.none B.nothing C.neither D.no one

A
表示没有一种药

B是没有什么的意思
C用于两者之间
D用于修饰人

答案为A。
none做代词,代指上文的medicine,“这名病人尝试了很多种药,但没有一种对他的病有效。”
B. nothing什么也没有;
C neither两者中一个也不行;
D no one没有一个人

这个病人已经试过相当多种类的药物了,但是--对他的疾病没有任何效果
这类根据句意是否定的表达,并且这个否定的代词要代指medicine 
所以选 none 可以指人也可指物
nothing表示事物
neither 两者都不
No one代指人
希望对你有帮助哦~

The patient has tried quite a few kinds of medicine,but ______ had any effect on his disease.
