第一題D NOne of them is等于all of them are not,所以要用aren't they
第二題have ,each放在復(fù)數(shù)名詞之后只起強(qiáng)調(diào)作用,真正的主語還是前面的復(fù)數(shù)名詞.
第三題C little和much這里都是不定代詞,只能用第三稱單數(shù)
樓上不要誤導(dǎo)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做代詞時(shí)用第三人稱單數(shù)
