  介词   (一) 知识概要   介词在英语中用法很活,也无一定规律可循。在初中范围内还应学一个记住一个,特别是那些和动词的特殊搭配。这样长期下去不断学习自然会总结出一套自己的规律来。下面是一般的规......

  [析] since用来表达主句动作的开始时间,所以其引出的从句中应为过去时,而不能用完成时态

  [误] I can help you repair this bike. You will get it after two hours.

  [正] I can help you repair this bike. You will get it in two hours.

  [析] 中文经常讲两小时之后来取,两天内会修好,而这个介词在英文中要用in而不要用after。其原因有二,①after 多用于过去时,如:I arrived in New York. After three days, I found a job in the bank. ② after 加时间是表达一个不确定的时间范围,如:after three days, 即三天之后的哪一天都可以。所以在许诺若干时间内会完成某事时,一定要用介词in。

  [误] Three days after he died.

  [正] After three days he died.

  [正] Three days later he died.

  [析] after 与 later都可以用来表达一段时间之后,但它们所处的位置不同,after 在时间词前,而later在时间词后。

  [误] She hid herself after the tree.

  [正] She hid herself behind the tree.

  [析] after多用来表达某动作之后,所以有的语法书中称它为动态介词,如:I run after him. After finishing my homework, I went to see a film. 而behind则多用于静态事物之后。

  [误] There is a beautiful bird on the tree.

  [正] There is a beautiful bird in the tree.

  [析] 树上长出的果实,树叶要用on, 而其他外来的人、物体均要用in the tree.

  [误] Shanghai is on the east of China.

  [正] Shanghai is in the east of China.

  [析] 在表达地理位置时有3个介词:in, on, to。 in表示在某范围之内; on表示与某地区接壤;to则表示不相接。如:Japan is to the east of China. 

  [误] I arrived at New York on July 2nd.

  [正] I arrived in New York on July 2nd.

  [析] at用来表达较小的地方,而in用来表达较大的地方。at常用于at the school gate, at home, at a bus stop, at the station, at the cinema, at a small village。

  [误] He lived in No. 3 Beijing Road.

  [正] He lived at No. 3 Beijing Road.

  [析] 在门牌号码前要用at, 并要注意它的惯用法:at the end of the street, at the foot of the mountain, at the top of the page。

  [误] There is a colour TV set at the corner of the hall.

  [正] There is a colour TV set in the corner of the hall.

  [析] 在屋内的角落应用in,而墙的外角用at,如:There is a tree at the corner of the street.

  [误] This weekend I'll stay in Uncle Wang's.

  [正] This weekend I'll stay at Uncle Wang's.

  [析] 要注意英文的特殊表达法,如:at a tailor's shop (裁缝店)=at a tailor's, at the doctor's (去看病) at the bookseller's (在书店) at uncle Wang's (在王叔叔家)

  [误] Do you know there is some good news on today's newspaper?

  [正] Do you know there is some good news in today's newspaper?

  [析] 在报纸上的新闻要用in, 而在具体某一版上,或某一页上则要用on。

  [误] The school will begin on September 1st.

  [正] School will begin on September 1st.

  [析] 这里的school应看作不可数名词泛指学校的课程,即开学之意。要注意,有些活动场所当表达正在从事该种活动时不要加冠词,如:at table (吃饭), When I came to Tom's home, they were at table. 还有: at desk (学习),at work (工作) at school (上学), in hospital (住医院) at church 作礼拜如加上定冠词则另有他意,如:at the school 即在学校工作或办事,in the hospital 即在医院工作或去看望病人。

  [误] In my way to the station, I bought a newspaper to kill time.

  [正] On my way to the station, I bought a newspaper to kill time.

  [析] 译文为:在去车站的路上我买了份报纸,为的是消磨时光"在……的路上"应用on one's way…。而 in the way 有挡道之意,如:Please move the chair it is in the way。

  [误] Look, the door is open, Maybe someone broke into.

  [正] Look, the door is open, Maybe someone broke in.

  [正] Look, the door is open, Maybe someone broke into the office.

  [析] in是表达一个静止状态,在与break连用时其后不加介词宾语,而into则是动态介词,与break连用时要加介词宾语。

  [误] I'll leave Beijing to Shanghai tomorrow.

  [正] I'll leave Beijing for Shanghai.

  [正] I'll leave for Shanghai.

  [析] leave for 是离开某地去某处的固定搭配,不可将for改为别的介词。这样的搭配还有:start for 动身前往某处,set out for, sail for。

  [误] I'm sorry. I have to get out the bus at next stop.

  [正] I'm sorry. I have to get out of the bus at next stop.

  [析] get in, 与 get out是两个相反的词组。get in 为上车,而get out为下车,但语法家认为这里的in与out为副词,所以其后不能接名词,我们可以讲We'd better get in. 或We'd better get out. 还有一组词组有关上下车:get on/off(a train, a ship, a struck) get into/out of (a car, taxi…)

  [误] Be careful The temperature of the water is ninety degrees over zero.

  [正] Be careful. The temperature of the water is ninety degrees above zero.

  [析] over 与 above 在作为比某物高的意思时有时可以互换。但在垂直方向上的高矮时,即正上方时则要用above.而泛指上方时用over.

  [误] There is an old stone bridge above the river.

  [正] There is an old stone bridge over the river.

  [析] over还有一意为"跨越,横跨"。

  [误] The Dead Sea is under the sea level.

  [正] The Dead Sea is below the sea level.

  [析] 在垂直下方要用below.也就是讲above与below互为反意词,over与under也是反意词。

  [误] There is a big tree in the front of the house.

  [正] There is a big tree in front of the house. 

  [析] in front of 是在物体外部的前面,而in the front of 是在物体内部的前面,如:The driver sits in the front of the bus.

  [误] It took them two days to walk across the forest.

  [正] It took them two days to walk through the forest.

  [析] across 作为介词有两个主要意思:① 横过,如:I want to walk across the street.② 对面,如:There is a post office across the street,而through 多用于三维空间中的穿越。across则多用于平面上的横过。如:The little girl ran across the room to meet her mother.

  [误] The sun sets toward the west.

  [正] The sun sets in the west.

  [析] towards也可用作toward,它主要表达朝向某方向运动,但不一定到达,如:He ran toward(s) the mountain.而在表示方位east, west, north, south 时,其前面要用in。要注意的是这4个词可以用作副词,如:I went south. 也可用作名词,如:I went to the south.也可用作形容词,如:I went to the south part of China.

  [误] Do you have no other clothes except those?

  [正] Do you have no other clothes besides those?

  [析] beside 是"在……旁边",如:The students stood beside their teachers.而besides是"除……之外,不仅……而且……,除了……以外还有……", 如:I studied English besides French, when I was in college. 而except 则是从同一类物体中去掉某一部分,如:I come here every day except Sunday. 而except for 是指去掉不同种类的事物,如:The room is clean except for two chairs. 而except that则要加从句。

  [误] Can I write the exam paper with ink?

  [正] Can I write the exam paper with a pen?

  [正] Can I write the exam paper in ink?

  [析] with后要加拿得起来放得下的工具,而墨水、颜料等原料则要用in。

  [误] I'm earlier today. I came here by his car.

  [正] I'm earlier today. I came here in his car.

  [析] 在交通工具前加介词by,但不能再有任何指示代词或冠词,否则要改换相应的介词。by taxi=in a taxi

  by train=in a train

  by bicycle=on a bicycle

  by ship=on a ship

  [析] be good at 为"擅长某事",而be good for somebody为对某人很好。

  [误] It was good to you to help my little boy.

  [正] It was good of you to help my little boy.

  [析] 这句话应译为:你真太好了,帮助了我的小孩。而be good to somebody 是对某人态度好。如:Her mother is good to everyone.
