不定代词
不定代词：不指名代替任何特定名词或形容词的代词叫做不定代词。常见不定代词如下所示：
不定代词的用法中有几点需要注意：
1. some 和any 既可修饰可数名词复数，也可修饰不可数名词。some 多用于肯定句，any则多用于否定句、疑问句和条件从句。例如：
A: Are there any apples in the fridge?
B: Yes, there are some. / No, there aren’t any.
A: Is there any water in the bottle?
B: Yes, there is some water. / No, there isn’t any water.
但是，在Would you like some tea? 这类问句中则用some, 而不用any, 这是因为问话者希望得到对方肯定的答复。
