介词：
1、介词的主要用法：
介词是一种虚词,不能独立使用。介词之后一般有名词或代词(宾格)或相当于名词的其他词类、
短语或从句作它的宾语,即构成介词短语。有些介词是由两个以上的词构成的短语介词,如：

3、介词短语的句法作用：
介词短语相当于一个形容词或副词,可用作状语、定语和表语。如：The man came
<down the stairs>.(状)(那个人走下楼来)/The woman <with a flower on her head> is from the
countryside.(定)(头上戴花的妇女来自乡下)/The teacher is now with the students.(表)(老师现
在和学生在一起)
4、介词短语在句子中的位置：
介词短语做状语时,如果表示时间/地点,可以放在句首或句尾,如果表示方向/方
式/伴随/涉及/原因/目的/比较,一般放在句尾；介词短语作表语时放在连系动词之后；介词
短语作定语时,只能放在被修饰的名词之后。如：He wanted to find a good job in Shanghai
the next year.(状语)(他想来年在上海找份好工作)/ They searched the room for the thief.(他们
在房间里搜索小偷) / The letters are for you.(表语)(信是给你的)/ Have you seen a cat with a
black head and four white legs?(定语)(你看见一只黑头白腿的猫了吗？)
5、重要注释：
⑴ this / that / these / those / last / next / a / every / each等词构成的时间短语,前面不用
任何介词。如：Every year travellers from abroad come to visit Pingyao.(每年都有国外的游客来游览平窑镇)/ He had a bad cold that week.(那个星期他患重感冒)
⑵ 记住一些固定词组： on foot(步行), at night(在晚上), play with(玩耍……),look out
of(朝…外面看), with one’s help(在…的帮助下),look after(照料…),look for(寻找…),on a
bike(=by bike)骑车, help sb. with(帮某人做…)等等。
6、某些介词的用法辨析：
⑴ 时间或地点介词in、on、at的用法区别：表示时间时, in表示在一段时间里(在将
来时句子中则表示在一段时间之后), on表示在具体的某一天或者某天的上下午等, at表示
在某个时刻或者瞬间； 表示地点时, in表示在某个范围之内, on表示在某个平面上或与
一个面相接触,at则表示在某个具体的场所或地点。如：He was born on the morning of May
10th.(他出生于五月十日的早晨)/ I usually get up at 7：00 in the morning.(我通常在早上的七
点钟起床) / His glasses are right on his nose.(他的眼镜就架在他的鼻子上)/ He is at the
cinema at the moment.(此刻他正在电影院)
⑵ after与in表示时间的用法区别：“after+(具体时刻/从句)”表示“在…时刻之后”
常用于一般时态；“in+(一段时间)”表示“在(多久)之后”,常用于将来时态。如：He said
that he would be here after 6：00.(他说他六点钟之后会来这儿)/ My father is coming back
from England in about a month.(我父亲大约一个月以后从英国回来)
⑶ by、in与with表示方式的用法区别：都可以表示“工具、手段”,但是by主要表示
“乘坐”某个交通工具或“以……方式”, in表示“使用”某种语言/文字,with表示“使
用”某个具体的工具、手段。如：We see with our eyes and walk with our feet.(我们用眼睛看
东西,用双脚走路)/ Please write that article(文章) in English.(请你用英语写那篇文章)/ Let’s
go to the zoo by taxi.(我们打的去动物园吧。)/ It was written by Lao She.(那是老舍写的)
⑸ in front of 与in the front of： in front of“在…的前面”, 与in the front of“在…的前
部”。如：A car was parking in front of the hall.(大厅跟前停着一辆汽车)/ In the front of the
hall stood a big desk.(大厅前部立着一个大讲台)
