4、（若干时间）内“ ，常用 within。比较： the meeting will end in 30 minutes （三十分钟后）会议三十分钟后结束。 can you finish it within 30 minutes？（三十分钟内）你能在三十分钟之内完成这件事吗？ 但在过去时态中，in 可用于表“ 在若干时间以内 “，这时不要误用 during。 the job was done during a week （wrong） the job was done in a week （right ）这工作在一星期内就完成了。 4after 表示“在（某具体时间）以后“，注意不要和 in 的
5、2）意混淆。 after supper（8 oclock，the war）晚饭（八点、战）后 比较：he will be back in two hours他将在两个小时以后回来。 he returned to his hometown after the war战后他回到了故乡。 5for 表示“ （动作延续）若干时间“ ，有时可省略。 i stayed in london（for）two days on my way to new york在去纽约的途中，我在伦敦呆了两天。 6since 表示“自（某具体时间）以来“，常用作完成时态谓语的时间状语。 since liberation（198
6、0）自从解放（1980 年）以来 they have been close friends since childhood他们从小就是好朋友。 注： （1 ）since the war 是指“自从战争结束以来“ ，若指“自从战争开始以来“，须说“since the beginning of the war“。 （2）不要将 since 与 after 混淆。 比较：he has worked here since 1965 （指一段时间，强调时间段）自从 1965 年以来，他一直在这儿工作。 he began to work here after 1965 （指一点时间，强调时间点）从 196
7、5 年以后，他开始在这儿工作。 7by 表示“到的时候 “，其谓语时态的用法：动作动词常用完成时态；状态动词（be ）常用一般时态。 比较： by noon， everybody had（will have）arrived there by noon，everybody were（will be）there 到中午的时候，大家都（将）到那儿了。 以上探讨了介词表示时间概念时的用法和比较，上述介词除表示时间概念外还有其他的用法，英语学习者必须掌握其各种用法，才能灵活运用，提高自己的语言能力。 小学英语语法复习要点（一）一、名词复数规则1一般情况下，直接加-s，如：book-books, bag-
