都可用于复数可数名词和不可数名词之前。All用作不定代词时，其后常跟由关系代词that引导的定语从句，这时all that可写成what，值得注意的是：both, all用于否定句时，只是部分否定，意为―并不都……‖, ―不都是‖。
③ some, any: some多用于肯定句，any多用于否定句或疑问句中。但向对方征求意见或提出请求时，疑问句中也可用some;而any用作―任何‖解释时，可用于肯定句或条件从句中。
④ another, other，the other, others, the others: another指―又一个（些）‖或―另外一个（些）‖，如another apple, another five people等；other指―其他的‖，其后常跟名词，如other students, other rooms等；the other指两者中的―另一个‖或―另一方面‖，如She has two daughters, one is a nurse, the other is a teacher.；others指―他人‖或―他物‖（不一定是其余的全部），如After class, some students are playing chess, some are singing, others are playing basketball on the playground.；the others指（除前面提到的以外的全部），如There are fifty students in our class, twenty of us are from the city, two of us are from Dafeng, the others are from the countryside.
⑤ neither, none: neither表示―两者都不‖（与both相反），none表示―三者或三者以上都不‖（与all相反），它们都是全部否定的句子。 ⑥ (a) few, (a) little: (a) few修饰或代替可数名词，（a）little修饰不可数名词； few和little表否定意义，a few和a little表肯定意义。它们都能与副词quite, only连用，构成quite a few, quite a little（很多）和only a few, only a little(很少)。 二、代词专项练习 （1）
