第四節(jié) 不定代詞
　　不定代詞的用法區(qū)別在TOEFL中經(jīng)常出現(xiàn)，這些區(qū)別對許多同學(xué)來講比較容易混淆
　　一、比較both 和All
　　Both，either, neither都是在談到兩個人或者東西的時候用到
　　Both of them are right. (他們兩個人都對)
　　You can take either book.(兩本書你可以任意挑一本)
　　Neither of them is going to get haircut. (他們倆誰也不愿意理發(fā))
　　All of the books are worth to read. (三本書以上)
　　None of them is going to get haircut. (them指三個人以上)
　　I like any of them. (them指三個人以上)
　　二、None 和no
　　None和no都用于否定的意思。但是None是“沒有一個人或者沒有一個東西”，在句子中可以用作主語、賓語、同位語等。而No是“沒有”的意思，只能夠當(dāng)作形容詞用，不能夠作代詞用。
　　None of them knew how to do it. (不能夠說no of them)
　　No women are allowed to come in.
　　三、another, the other, others, the others
　　1．在涉及到兩個人或者東西的時候，任意取一個用one, 另外那個用the other(表示特指)
　　I have two computers; one is IBM, the other is Dell.
　　2．涉及到三個以上時，任意取一個用one, 泛指另外一個用another
　　Three people went to the meeting. One was a software programmer, another was a network expert, and the third was a college student.
　　3．涉及到三個以上時，任意取一個用one, 表示特指其他的那些用the others或者用
　　the other+名詞
　　Two of them go to Canada, the others go to America.
　　(他們中兩個人去了加拿大，其他人去了美國)
　　Two of the students go to Canada, the other students go to America.
