I.知识点归纳 一.介词的分类 1. 简单介词(如at , by , for , from , in , with , to , on) 2. 复合介词(如into, onto , within , outside) 3. 双重介词(如at about , from behind , from among, until after) 4. 短语介词(如in front of , in spite of , by means of, in addition to等);有的介词可兼作连词(如after , until等) 二.介词的作用 介词往往跟后面的宾语一起构成介词短语,在句中可充当以下成分: 1. 定语 如The boys in blue vests are the students of our school. 2. 状语 如Can you write in English ? (方式状语) 3. 表语 如 Japan is to the east of our country 4. 宾语补足语 如Make yourself at home. 三.常考易混的几种情况 1. at , in , on 和by表示时间 1) at ①表示时间的一点,时刻等 at sunrise , at daybreak , at dawn , at noon , at dusk , at midnight ②较短暂的一段时间,某个重大节日等at night , at midsummer , at Christmas , at New Year , at the Spring Festival 2) in ①用于某个较长时间(如年,月,星期,世纪,朝代,泛指的上、下午、傍晚等) ②在一段时间之后 Father will be back in a week. 3) on ① 具体的时日和一个特定的时间,如某日、某个星期几等 We began to work on our arrival. ② 某个特定的早晨、下午或晚上On the eve of victory (胜利前夕) ③ 准时,按时 on time 4)by ① 不迟于,在(某时)前 He must have finished it by now ② 在…间,在…时候 We work by day and sleep by night. 2. besides , except , but , except for , except that / when … 1)besides 表示除了…以外,还有,但用于否定句时,与except , but 同义 We have no other books besides (=except) these. 2) except 表示(某人或某物)除外 They all went to see the film except John. 3)but 意为除了,与except 同义。Except 强调被排除的部分,but 则强调整句的内容,常修饰否定意义的代词或疑问代词。 She could do nothing but wait for the next bus. / Who would play all day but Jack ?
4)except for 表示除去整体中的一部分,有除了因为…(with the exception of)的意思,它所叙述的事实或细节部分地修正句子的主要意思。 The composition is good except for a few spelling mistakes. 5)当except 用于句首时,后面往往也要加上for. Except for this , everything is in order . = Everything is in order except this. 6)连接从句时except 后要用适当连词 This suit fits me well except that the trousers are a bit longer. He does morning exercises except when it is raining. 3. in , to 和on的表示方位 1) in表示在…之内 Fujian lies in the south of China. 2) to 表示在某范围之外的地方.

It will stop the sand from moving towards the rich farmland in the south. 注意:towards还有“快要到、快接近”的意思,紧跟在后面的名词前常不用冠词。 5.介词的省略 1)表示时间时,用在next , last , this , these , yesterday , tomorrow , one , any , every , each , some和all等词之前的at , on , in通常都省略。如:this evening , yesterday morning , one day , every week 2)在某些名词词组前,可省,也可不省。如 (at ) the following weekend, (on) that day , (in) the year before last 3)表示时间的for 的省略,要看具体情况 ①以 all开头的名词短语,表示延续的时间,for 须省略I stayed with her all the morning. ②表示一段时间的短语之前,for 可省,也可不省We're been here (for) three weeks. ③否定句中 for 不能省。I haven't seen him for ten years. ④时间状语位于句首,不能省for.
