介词为虚词,不能单独充当句子成分,必须同名词、代词、短语、句子构成介词短语,才能充当句子成分。介词短语在句中常作表语、定语、状语和补足语。介词的用法比较复杂,在英语学习中须多多注意。 想看基础知识,请看介词。
下面我们来学点介词口诀。帮你快速记单词。
一、介词及介词短语
介词像个“游离体”, 名前动后常出现,
一旦组成“某结构”, 句中成分有一位。
“介+宾”叫“介短”, 作“形、副”句里边。
“宾补、表、定、状”, 都能用得上①。
“动+介”——动词性②, “及、不及物”谓语用。
成语、习语常固定, 应用起来有弹性。
注 ①介词后面的名词、代词或数词是介词的宾语,介词和介词宾语合成介词短语。介词短语在句中的语法作用相当于形容词或副词,在句中做宾(主)语、补足语、表语、定语或状语。
②“动词+介词(副词)”组成一个动词词组或短语动词,其语法作用相当于一个及物动词或不及物动词,在句中作谓语。
二、介词在句中的位置
介词活跃句关键, 短语合成形简单,
独作成分看不见, 介短表定状可担。
before时空在之前, after之后off远。
直上 over,above斜, under,below下相反。
直到till,on表面, 穿过through,for因缘。
by表旁边in里面, with伴随by车船。
时间地点at、in、on, 二者between多among,
behind后面beside旁, 附近near沿着along。
from来自like像, 表示目的for,to当。
of所属周围round, 向上up向下down。
三、on,at,in用法巧记
on,at,in这三个常用介词都可以表示时间和地点,但具体用法不同,多数学生对它们混淆不清。现在只要记住了口诀,就可避免at,on,in的种种误用。
1. on,in,at表示时间
on“在具体某一天”①
“当某时”,动名词, arrival,death前;
用in一般“上”“下”“晚”;
on用于天,in用于月、季、年③;

at是个时间点,
“工作”“时刻”与“圣诞”⑤。

习惯用语记心间。

例 On Mother's Day, we should sned flowers to our mother. 母亲节,我们应该送花给我们的母亲。
On my arrival home,I found he had gone already.当我到家时,我发现他已经走了。
② 当early,late用于句首修饰介词短语时,尽管表示具体某一天的上午、下午、晚上,都要用in,泛指一般的上、下午,晚上也用in 。

Xiao Ming was born in December of 2004. 小明生于2004年12月。
④当 morning,afternoon,evening有前位定语或后置定语限定时,就不用in而用on。
例 on a hot (summer) noon 在一个炎热(夏天)的中午
on Monday Morning 在星期一上午
on the morning of March 8th在3月8日上午
⑤ 表示某时某刻及在work,Christmas前用at。
例 We get up at eight o’clock. 我们8点起床。

2. on,in,at表示地点
on“在之上”接触面,“靠近、接壤、左右边”①;
in“在里面”和“中间”②;
at表示小地点, “入口、车站、电影院”③;
home出现定语、冠, 须用in把at换④;
“夜间、车辆”若有限, 及“在途中”on在前⑤。
注: ①在表示地点时,指“在……之上(与表面接触)” “靠近、接壤”及“在左右边”都用on。
例 There is an English-Chinese dictionary and two grammar books on the big desk.那张大写字台上有一本英汉词典和两本语法书。

在英语中,介词(preposition)虽然是一种小词,但在作用和运用上的复杂性却不可小看。首先,可以毫不夸张地说,离开了介词的中介或连接作用,就无法表达某些最基本的思想或概念。以时间为例,大到年代,小到日月,要表示某些特定的时间或时刻,离开介词有时就会寸步难行。比如"今年"虽然可以说this year,但要表达"在2000年",就不能省略介词,而要说in 2000;"这个月"是this month,但"6月里"则需要说in June;"今天"虽然有现成的today一词,而如果是"在6月5日"就要说"on June 5th","在星期五"就得用on Friday(但在某些新闻报道里这些介词也可以省略不用)。再以位置为例,我们可以随便举出book和desk两个词,然后用介词表达出各种位置关系:the book on the desk(桌子上的书)、the book under the desk(桌子下面的书)、the book near the desk(桌子附近的书)、the book beside the desk(桌子旁边的书)等等。
介词不仅具有重要的表达意义的功能,而且在使用上也十分复杂。造成这种复杂现象的原因是多方面的。首先,单个介词(即由一个词语构成的介词,与此相对的是复合介词,比如upon,into,within,without等)本身的意义具有相当的复杂性,以in和on为例,in的基本意义是"在里面",表示一种范围,on的基本意义是"在上面",表示两种东西相接触,然而在speak in English(用英语说)和on the team(在队里当队员)两种形式中,in和on表达的则是引申意义;the boat on the lake指的是"湖上的船",但the cottage on the lake则表示"湖边的小屋"。
其次,英语中的单个介词虽然只有60个左右,但这些介词却可以同其他词类灵活搭配,构成为数众多的短语形式:
1.介词加名词构成的短语,由称介词短语,如by accident(偶然地),on purpose(故意地),for example(例如)in conclusion(总之)等。
2.由名词加介词构成的短语,比如concern for(对……的关心),love for(对……的热爱),satisfaction with(对……满意),confidence in(对……的信任),loyalty to(对……的忠诚)等等。
3.由动词加介词构成的短语,例如insist on(坚持要……),differ from(不同于,区别于),distinguish between(区别,区分),benefit from(从……得到益处,受益于……),conform to(符合)等等。
4.由形容词加介词构成的短语,比如be keen on(对……很热衷),be worried about(为……而担心),be fond of(喜欢),be strict with(对……很严格),be loyal to(终于……)等等。
上述这些搭配形式大都具有固定性,运用时常常来不得半点差错。比如比如be interested只能和in搭配构成介词短语,according和instead只能分别与to和of搭配构成两种短语介词。
此外,英语中还有一类短语介词,也即由介词加其他此类构成的短语,但作用相当于一个介词,比如in front意思接近before,in spite of和despite是一个意思,apart from和意义也很相近等等。短语介词还有很多,再如according to(根据),along with(随同……一起),because of(由于),by means of(依靠),instead of(代替),in accordance with(与……一致,依据),on behalf on(代表),owing to(由于),together with(和……一起),with regard to(关于),as for(至于),as to(至于),in view of(鉴于),for the sake of(为了……),on account of(由于)等等。
最后,单个介词还可以用在一起,这种现象称为双重介词,比如from within(从……里边),from behind(从……后边),from inside(从……里边),from outside(从外边)等等。
其三,同一个介词和不同的词语搭配或者同一个词语和不同的介词结合都可以产生不同的意义,前者如be good at(善于),be bad at(不善于),后者如agree with sb.(同意某人),agree on sth.(同意某事);在有些情况下,同一个介词和不同的词语搭配或者同一个词语和不同的介词结合有时也能产生相同的意义,前者如depend on(依靠),rely on(依靠),count on(依靠),后者如be good at(善于),be skillful in(善于)。
其四,有些结构用不用介词意义完全相同,比如consider后面的as就可以省略而意义不发生变化,而在有些结构中,有无介词意义则不完全相同,比如《红楼梦》中的刘姥姥初进大观园时会说:It is beautiful in here. 而贾府的丫鬟则会应酬说:Yes, it is beautiful here. 刘姥姥的话含有一种对比意义,即大观园和外面相比简直是两个世界,丫鬟已在贾府住习惯了,因此她的话就没有这种对比意义,所以刘姥姥就用了带有比较意义的in here,而贾府的丫鬟则用了没有对比意义的here。
除上面提到的几点外,英汉语不同的表达习惯也增加了介词学习的复杂性,比如英语说in the sun, in the moon,汉语则说"在阳光下"(英语的under the sun是"普天之下"的意思)、"在月光下";英语说The sun rises in the east and sets in the west,汉语则说"太阳从东方升起,从西方落下",或者不用介词,干脆说成"太阳东升西落";英语中的the hole in the wall, the nail in the wall, the map on the wall三个短语中用了不同的介词,而汉语则都用一个"上"字来表达:墙上的洞、墙上的钉子、墙上的地图;汉语可以直接说打某人的某个部位,英语则要先说打某个人,然后再通过介词去打某个部位:beat sb. on the head(打某人的头),同样,英语要说抓着某人某个部位,就得先说抓着那个人,然后再用by来表示被抓着的部位grasp sb. by his hand(抓着某人的手);英语中有besides和except两个词语,汉语可以用"除了"一种形式来表达,但汉语的"除外"既可以指包括,又可以指排除,在这两种不同的情况下,英语就得分别用两个介词来表示:
We all went there besides John. 除了约翰我们也去了那里。(即约翰去了,我们也去了)
We all went there except John. 除了约翰我们都去了那里。(即我们都去了,但约翰没去)
最后,为了解释英语介词用法上的复杂性和灵活多样性,我们特以from一词为例来作进一步的说明。
1.表示纯粹的分离,作"分开"、"分离"、"隔开"、"离开"解,常构成下列表达形式:
separate the good from the evil(把好的和坏的分开)
remove from the city to the countryside(从城市移居乡村)
part from a friend(断交)
depart from one's hometown(背井离乡)
keep away from dangerous things(远离危险)
flee from prison(逃离监狱)
keep (stand. aloof from the society(离群索居)
rise from table(离席)
fall from a tree(从树上掉下来)
withdraw from a meeting(离会)
move from one place to another(从一处迁至另一处)
retire from one's work(退休)
live apart from other people(离群索居)
2.表示"消失"、"消除":
The plane soon disappeared from sight. 飞机很快消失不见了。
After hearing this, the smile fled from her face. 听到这里,她的笑容立即消失了。
Let us remove all doubts from our minds. 让我们消除相互间的猜疑吧。
3.表示"禁止"、"戒除"、"免除"、"解除"、"除去"、"使免除"、"使脱离"等,有时具有否定意义,常构成下列表达形式:
remove dirt from a table(除去桌子上的灰尘)
release sb. from his suffering(解除某人的痛苦)
clear the land from trees(伐去地上的树木)
free sb. from debts(免去某人的债务)
dismiss sb. from his service(解除某人的职务)
expel (dismiss) a student from school(开除学生)
be excused from punishment(被免去处罚)
be safe from danger(没有危险)
be secure from danger(没有危险)
be free from anxiety(无忧无虑)
rescue a person from danger(救人于危难)
