In/on/at到底怎么用

In, on, at 这三个介词可以说是所有烤鸭最熟悉的单词了，从开始学英语时便开始接触，然而，你真的搞清楚，弄明白，用对了吗？小雅哥在平常的批改作文的过程中，发现同学们普遍in/ on/ at傻傻分不清楚，在这些最基本的地方犯错误，并因此拉低作文分数可就不好咯~

下面小雅哥就从修饰时间，表达方位，固定用法这三个方面来分析这些介词到底如何正确的使用！~

修饰时间
我们先来比较这几个句子：
They arrived at 5 o’clock.
They arrived on Friday.
They arrived in October. / They arrived in 1988.

修饰时间的用法应该是同学们最熟悉，最不会犯错误的了，毕竟从初中老师就开始教：时间点用at，具体某一天用on，大的时间如月份、年份等用in。如：

At the time of a day

At 11:45; at midnight; at lunch time; at sunset

On days/dates

On Fridays; on Christmas day, on my birthday

In longer time periods

In October; in 1998; in the 18^th century; in the middle ages

但同时，还有以下用法同学们需要注意：

1. Last/ next/ thus/ every等词钱不用at/ on/ ine.g. I will see you next Friday

2. In + 时间表示将来

e.g. The train will be leaving in a few minutes. (= a few minutes from now)

也可以说： in six months’ time, in a week’s time etc.

e.g. They are getting married in 6 months’ time.

3. 避免混淆on time 和 in time; at the end 和 in the end

On time = punctual, not late. 即守时

If something happens on time, it happens at the time that was planned.

E.g. The 11.45 train left on time. (准时出发，没有延误)

反义词： be late.

In time (for something/ to do something) = soon enough

e.g. will you go home in time for diner? (= soon enough for dinner)

反义词：too late

4. 避免混淆 at the end和 in the end

At the end (of something) = at the time when something ends

e.g. at the end of the month, at the end of the film, etc.

At the end of the concert, everyone applauded.

注意：并没有in the end of…这种说法

反义词： at the beginning of

In the end = finally,我们用in the end 表达最后结果发生的处境

E.g. we had a lot of problems with our car. We sold it in the end. (= finally we sold it)

反义词： at first 一开始

E.g. At first, we didn’t get on very well, but in the end we became good friends.

表达方位

In 表示在…中间，例如：

In a room/ building/ box/ garden/ town/ pool… etc.

E.g. There are some people swimming in the pool/ in the sea/ in the river.

At 表示在某一个地点，例如：

At the stop/ door/ roundabout/ reception

e.g. Turn left at the traffic lights/ at the church/ at the junction.

On 在….之上，例如：

On the ceiling/ door/ floor/ table/ wall/her nose / on a page / on an island

e.g. Have you seen the notice on the notice board / on the door?

In 与 at

There were a lot of people in the shop. It was very crowded.

很多人在商店中，很拥挤。

Go along this road, then turn left at the shop.

沿着这条路笔直走，在商店的地方左转。

In 与 on:

There is some water in the bottle.

There is a Label on the bottle.

At 与 on:

There is somebody at the door. Shall I go and see who it is?

有人在敲门。我们要不要去看看？

There is a notice on the door. It says 'do not disturb’.

门上有个告示，写着‘请勿打扰’

固定用法：

1. in hospital / in prison / in jail/ at work, etc.

住院/坐牢/工作，等等

e.g. Anna's mother is in hospital.

I'll be at work until 5.30.

Julia is studying chemistry at university.

2. At home

当我们想表达某人在家时，使用is at home 或者 is home (有没有at都可以), 但当我们想说明在家做某事时一定要说at home

e.g. Shall we go to a restaurant or eat at home?

3. At a party / at a concert etc.

在party上/ 在演唱会上/在参加某个活动时

e.g. Were there many people at the party / at the meeting / at the wedding?

4. 建筑物In 和 at 的用法

in 和 at 都可以和building连用.比如，可以说 eat in a restaurant 或者 at a restaurant; 买东西可以讲 buy something in a supermarket 或者 at a supermarket. 当我们形容某个活动发生在某个场地时，用at (e.g. a concert, a film, a party, a meeting):

e.g. We went to a concert at the National Concert Hall.

There was a robbery at the supermarket.

5. at the station / at the airport

e.g. There's no need to meet me at the station. I can get a taxi.

6. 在某人家里时，用 at somebody's house:

e.g. I was at Helen's house last night. or I was at Helen's last night.

当我们指建筑物本身时用in

e.g. It’s always cold in Helen's house. The heating doesn't work well. (not at Helen's house)

7. on a bus / on a train / on a plane / on a ship；In a car / in a taxi:

e.g. The bus was very full. There were too many people on it.
