N---of my parents can speak English

N___of my parents can speak English
应该填 Neither 解析如下：
1.none这个词很有意思,首先它是一个代词,也就是代替前边或后边提到的事物,如果没有提到就不用none.比如How many students are there in the cinema.None.none就代表只没有学生,可能有别人,How much tea is there in the glass,None.none就代表只没有茶,但有别的,但也句子无关了,none只代表前边提到的学生和茶没有.像None of us likes swimming.none就只代表我们中没有人.
2.Neither这个词也是代词不过它限定的是后边的东西必须是两者,Neither就表示两者任一者都没有.看似半否,实则全否.
3.none可以代表后边的东西必须是三者或三者以上.
