1. 介词概述:介词表示它与后面的名词或代词与其他句子成分的关系。介词是虚词,不能单独做句子成分。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。
2. 常用介词的意义和用法。
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 night of May 10th.
I usually get up at 7:00 in the morning.
His glasses are on the desk.
My brother is at the bus stop.
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”常用于一般过去时态;“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 come back after 6:00.
My father is coming back from Astralia in about a month.
⑶ since与for表示时间的用法区别:“since+(具体时刻/that-从句)”表示“自从…起一直到现在”,“for +(一段时间)”表示“持续一段时间”,都常用于完成时态;如:
My father has worked in this factory since 1970.
My father has worked in this factory for over 30 years.
⑷ 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”,在被动句中可以表示动作的执行者;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 write with our hands and walk with our feet.
lease speak in English.
Let’s go to the zoo by bus.
It was invented by Adison.
⑸ about与on的用法区别:都可以表示“有关…”,但是about的意义比较广,而on主要表示“有关…(专题/课程)”。如:
Tom is going to give a speech on the history of China.
They are talking about the English test.
⑹ through与across、over的用法区别: through指“穿过…(门洞/人群/树林)”; across和over可以指“跨越…(街道/河流)”,可互换,但是表示“翻过…”时只能用over. 如:
Just then a kangaroo (鼠)ran across the road.(就在那时一只袋鼠跑过路面)
There is a bridge across/over the river.(河上有座桥)
They climbed over the mountain and arrived there (他们翻过大山到达了那里)/
The visitors went through a big gate into another park.(参观者们穿过一个大门来到另一个公园)
(7)as与like的区别:两个词都表示“像……”,但是as译为“作为……”,表示的是职业、职务、作用等事实,而like译为“像……一样”,表示外表,不是事实。如:
Let me speak to you as a teacher.(我以老师的身份和你讲话。)
Let me speak to you like a teacher.(让我像一位老师一样和你讲话)
(8)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 group of people was standing in front of the hall.
In the front of the hall stood a group of people.
(12)except与besides的区别:except“除了”,表示排除掉某人物,即不包含;而besides“除了”则表示包含,即“不仅……又……”。如:
