1.表示时间的介词in的用法如下。表示在某一较长时间内，如世纪、年、月、季、周等一般用介词in，如：in the 1990s,in January, in(the)winter
in和during表一段时间内两词可互用。如：in the night, during the night, in the war, during the war。但略有区别：当接表示“活动”的抽象名词时多用during，接“活动”的动名词及短语时用in。如：during the discussion/in discussing the problem during her stay in Hubei/in playing basketball/during the course of/in digging the tunnel
2.在具体的某一天或某天上午、晚上、前夕，常用on。
3.表示某一时刻或某一点时间用at,如小时、分钟等。
有些时间名词前有one，each，any，every，some，all，next，last，that修饰时,不接介词。如：

4.till、until、to的用法。
(1)till(until)与持续动词连用一般用于肯定句中，与短暂动词连用一般用在否定句中。如：

但注意：在句首出现或强调句型中一般不用till而用。如：
Not until 9 a.m.did Mr.Smith come back to school.
(2) to表“终结”时常和from连用，但要注意不与from连用时的意义。如：
from July to September, from six to (till) eight(从……到……为止)，但from morning till night(从早到晚)，不能用to。

在否定句中，两词可以换用，如：He has no other hats except/besides this one.

(4) except that...“除了……一点以外”。如：He has not changed except that he is wearing dark glasses.
(5)but和except在表示“除了……以外”时可以通用，但应注意以下三点：前面有不定人词、疑问代词在意义上对称时，多用but。All but one are here. Nobody but I likes making model ships.后接不定式短语为排除对象时，多用but。He has nothing to do but wait.(前有do,后省to)；but与一些固定结构连用。have no choice but to do sth.只得做某事，can not but do sth.不得不,can not help but do sth.不得不……，but for...如不是……
7.介词的省略：
介词for表示时间的省略要求。

12. 表示“穿过……”的through和across：through表示从内部通过，与in 有关；across则表示从一端至另一端在表面上的通过，与on有关。如：Water flows through the pipe./ The old man walked across the street.
13. between, among：一般说来，between表示两者之间，among用于三者或三者以上的中间。如：You are to sit between your father and me./ He is always happy among his classmates.
