any
1.在否定句里，用any或every意思大不相同，该特别注意，如I do not know any (one) of them是“我对于他们一个也不认识”；I do not know every one of them是“我对于他们并不个个都认识”。
但I do not know any (one) of them虽然只有一个意思，I do not care to know any (one) of them却可能有两个意思：“我对于他们一个也不想去认识。”或“我对于他们并不任何一个都想去认识。”（哪个我想去认识，哪个我不想去认识，我自己有主张。）这第二个意思跟I do not care to know every one of them相仿。Not any person has read all these books也可能有两个意思：“没有人把这些书都读过。”或“并不是任何人把这些书都读过。”这里第二个意思跟Not every person has read all these books相仿。
2.在否定词后面用any既然是完全否定的意思，所以在要表示一部分的否定便不可用any，却该用some，比较下面各句：
I do not know any of them. （我对于他们一个也不认识。）
I do not know some of them. （我对于他们有几个不认识。）
If you do not know any of these words,... （假使你对于这些词一个也不识，…）
If you do not know some of these words,... （假使你对于这些词有几个不识，…）
3.把any用在主语里而在谓语里用否定词，这种说法是不合习惯的（我只见过一次），如可以说No man can do it，但不可说Any man cannot do it。下面几句都不可说：
Any book is not perfect. （该说No book is perfect。）
Any of his brothers is unmarried. （该说All his brothers are unmarried或None of his brothers are married。）
Any friend of mine knows no French. （该说None of my friends know French。）
Any language cannot be mastered in half a year. （该说No language can be mastered in half a year。）
4.any不可指两个人或物中间的任何一个，如不可说any of my two brothers，该把any改作either。
5.the＋属于最高级的词＋of any...是一个普通而不合理的结构，如He is the most handsome of any man I know和He has the best knowledge of English of any one of my friends。这两句可以改作He is the most handsome of all men I know或He is more handsome than any other man I know和He has the best knowledge of English of all my friends或He has a better knowledge of English than any other of my friends。
6.any用在属于比较级的词的前面，作at all解，如Is that any better? 和I will not do it any more。这种用法是英美通用的。在美国any往往用作at all解而并不用在属于比较级的词的前面，如I cannot help him any和He did not mind this any。any用作at all解，也用在different前面。例如：Is this any different from that?
7.I may leave here any time (that) I want to (leave here)里的that通常是省去的。
