介词用法知多少介词是英语中最活跃的词类之一。越是常用的介词,其含义越多。下面就简单介绍几组近义介词的用法及其搭配方法。 一. in, to, on和off在方位名词前的区别 1. in表示A地在B地范围之内。如: Taiwan is in the southeast of China. 2. to表示A地在B地范围之外,即二者之间有距离间隔。如: Japan lies to the east of China. 3. on表示A地与B地接壤、毗邻。如: North Korea is on the east of China. 4. off表示“离……一些距离或离……不远的海上”。如: They arrived at a house off the main road. New Zealand lies off the eastern coast of Australia. 二. at, in, on, by和through在表示时间上的区别 1. at指时间表示: (1)时间的一点、时刻等。如: They came home at sunrise (at noon, at midnight, at ten o’clock, at daybreak, at dawn). (2)较短暂的一段时间。可指某个节日或被认为是一年中标志大事的日子。如: He went home at Christmas (at New Year, at the Spring Festival, at night). 2. in指时间表示: (1)在某个较长的时间(如世纪、朝代、年、月、季节以及泛指的上午、下午或傍晚等)内。如: in 2004, in March, in spring, in the morning, in the evening, etc (2)在一段时间之后。一般情况下,用于将来时,谓语动词为瞬间动词,意为“在……以后”。如:He will arrive in two hours. 谓语动词为延续性动词时,in意为“在……以内”。如:These products will be produced in a month. 注意:after用于将来时间也指一段时间之后,但其后的时间是“一点”,而不是“一段”。如:He will arrive after two o’clock. 3. on指时间表示: (1)具体的时日和一个特定的时间,如某日、某节日、星期几等。如: On Christmas Day(On May 4th), there will be a celebration. (2)在某个特定的早晨、下午或晚上。如: He arrived at 10 o’clock on the night of the 5th. (3)准时,按时。如: If the train should be on time, I should reach home before dark//at dusk. 4. by指时间表示: (1)不迟于,在(某时)前。如: He will come by six o’clock. Jack had made some friends by the time you came. (2)在……间,在……的时候。如: He worked by day and slept by night. 5. through指时间意为“从……开始到结束”,此时与throughout相同。如: We work hard all through the year. 三. near, by, beside, at表示“在……附近”时的区别1. near表示相对的近,实际距离可能还很远。如:Suzhou is near Shanghai. 2. by和beside都表示靠近,实际距离不可能很远,但beside比by更具体地表示出“在……旁边”的意思。如: He was sitting beside her. 3. at也有“在旁边”的意思,但多表示有目的的行为所处的位置,而by和beside仅表示位置关系。如: The students are sitting at the desks listening to the teacher. Several students are sitting by / beside the window talking about a film. 四. at, in和on表示地点时的区别 1. at表示地点: (1)用于指较小的地方。如: I shall wait for you at the station. (2)用于门牌号码前。如: He lives at 115 Zhongshan Road. 2. in表示地点: (1)用于指较大的地方。如: He lives in Shanghai. (2)虽然是很小的地方,如果说话人住在那里,也可用in。商店、学校、机关等,若看作一个地点(point)用at,若看作一个场所(place)用in。如: I met him at the post-office. I’m now working in the post-office. 3. on表示地点,一般指与面或线接触,意为“在……上;在……旁”。如: The picture was hanging on the wall. New York is on the Hudson River. 五. besides, except, except for, but表示“除……外”之间的区别 1. 基本区别三者都可表示“除外”,但besides表示一种累加关系,意指“除了什么之外,还有…”;而except或but则表示一种排除关系,意指“除了什么之外,不再有…”。如:Besides his wife,his daughter also went to see him.除他妻子外,他女儿也去看过他(即妻子女儿都去看过他)。Nobody went to see him except [but] his wife. 除他妻子外,没有一个人看过他(即只有他妻子去看过他)。注:在否定句中,besides也表示“除…之外不再有…”,与but, except同义。如:No one passed the exam besides [except] Jim.除吉姆外,没一个人通过考试。2. 关于 but 与 except(1)两者都可表示“除…外不再有…”,但含义上略有差别:but侧重指意义的几乎完整性,而except则侧重指后面除去的部分。比较:All are here but one.除一人外都到了。All are here except one.还有一人没到。(2)在现代英语中,but的介词用法十分有限,一般说来,它只能用在下列词语之后:① no, no one, nobody, nothing, nowhere等② any, anyone, anybody, anything, anywhere等③ every, everyone, everybody, everything, everywhere 等④ all, none 等⑤ who, what, where 等Everyone knows it but you.除你之外大家都知道。I haven't told anybody but you. 除你之外,我没告诉任何人。No one but he [him] showed much interest in it. 除他之外没有一个人对此有很大爱好。一般说来,若没有出现上述词汇,就不宜使用介词but,否则可能造成错句。但是except 却没有以上限制。比较:正:The window is never opened except in summer. 除夏天外,这扇窗户从不打开。误:The window is never opened but in summer.(3) but一定不能用于句首,except通常不用于句首,如:除我之外每个人都累了。正:Everyone is tired but (except) me.正:Everyone but (except) me is tired.误:But (Except) me, everyone is tired.注:except for可用于句首,表示except的意思:正:Except for me, everyone is tired.3. 关于 except 与 except for:except主要用来谈论同类的东西,而except for 则主要用来谈论不同类的东西,有时含有惋惜之意。如:All compositions are well written except yours.除了你的作文外,其他的作文都写得很好。His composition is good except for a few spelling mistakes.他的作文写得不错,只是有几处拼写错误。4. 关于 except for 与 but for:except for主要表示排除,but for主要表示一种虚拟条件(与虚拟语气连用)。如:Except for me, everyone passed the exam. 除了我之外,大家都通过了考试。But for my help, she would not have passed the exam. 若不是我的帮助,她就不会通过考试。But for the atmosphere plants would die. 假如没有大气,植物就会死亡。5. besides的其他用法besides除用作介词外,还用作副词,其意为“此外”、“而且”,可用于分句句首(通常用逗号隔开)或句尾。如:I don't want to go; besides, I'm too tired. 我不想去,而且我也太累了。This car belongs to Smith, and he has two others besides. 这部车是史密斯的,此外他还有两部。六. above, over, on, up表示“在……上”之间的区别 1. above指“……上方”,表示相对高度,不一定在正上方,其反义词为below。如: We’re flying above the clouds. 2. over指“在……正上方”,表示垂直上方,其反义词为under。如: The bridge is over the river. 3. on表示“在……上面”,与物体表面接触,与beneath相对。如: There is a map on the wall. The earth felt soft beneath our feet. 4. up表示动作的方向往上,反义词为down。如:Please hang the picture up. 七. by, through, with表示“方式、方法、手段”之间的区别 1. by表方式: (1)表示以一般的方法或方式。如: No one in those days could live by writing poems. (2)表示传达、传递的方式或媒介。如: How did you send the letter, by airmail or by ordinary mail? (3)表示用交通工具、通讯工具后接名词单数,不加冠词。如: He came by train, but his wife came by bus. 注意下面两句的区别: Did you come by train? Did you come in his car / on my bike? “by +抽象名词”构成的词组有:by accident / by chance / by diligence / by effort / by force / by heart / by luck / by mistake / by hard work. 2. through表示“以;通过;经由”。如: He succeeded through hard work. 3. with表示方式 (1)表示行为方式,意为“以;带着;用”。如: We are well provided with food and clothing. (2)表示使用具体的工具或手段。如: He writes with a pen. 注意:在表示手段时,by, through, with有时也可换用,但with的意思更明确。如: Through / By / With his efforts he succeeded in making so many useful inventions. 八. through, with, from, for, at表示原因的区别 1. through表示原因,作“因为”解,常和neglect, carelessness, mistake, fault等词连用,表示偶然或消极的原因,如疏忽、过错、不慎等。如: He cut himself through carelessness. The experiment failed through one fault of ours. 2. with表示原因,指由于外界而影响到内部,意为“因为;由于”。如: The little girl was shivering with cold. 3. from表示动机、疲劳、痛苦、死亡等原因。如:She did it from a sense of duty. died from/of4. for常表示为了某一目的、事业的原因。如:Forgive me for keeping you waiting. 5. at表示原因,指“听到;看到;想到”等。如:At the news they felt very glad. 九. 介词的搭配方式 1. 介词可与名词搭配。如:answer to, key to, the reason for, the cause of, advice on, by means of, lack of, a picture of等。 2. 介词可与形容词搭配。如:be afraid of, be active in, be tired of, be bored with, be prepared for, be suitable for, be familiar to / with, be free from等。 3. 介词可与动词搭配。如:talk about, prevent…from, belong to, get over, depend on, object to, refer to, look forward to, make up for, devote/dedicate to等。your
