优质解答

第一题D NOne of them is等于all of them are not,所以要用aren't they
第二题have ,each放在复数名词之后只起强调作用,真正的主语还是前面的复数名词.
第三题C little和much这里都是不定代词,只能用第三称单数
楼上不要误导呀
Little is also a pronoun.
In general,employers do little to help the single working mother...
Little is known about his childhood.
Much is also a pronoun.
...eating too much and drinking too much...
There was so much to talk about.
≠ little
以上摘自collins字典第五版,例句都可以看出much和little做代词时用第三人称单数
