內(nèi)容簡(jiǎn)介

介詞 “at、on” 和 “in” 都可以用來(lái)表示人或事物所在的位置或地點(diǎn)。其中，哪個(gè)詞表示 “在物體的表面上”？哪個(gè)指 “在立體空間內(nèi)”？看視頻，聽(tīng)主持人 Sam 講解 “at、on” 和 “in” 在表示位置時(shí)各自的用法。

文字稿

Hello, I'm Sam and in this lesson we're going to look at the differences between at, in and on for location.

At can be used to talk about a single specific location. I'm at work. Or: I'm at the BBC right now.

On is used in relation to a surface. I'm sitting on a chair.

And in is used to talk about a three-dimensional space, usually with four walls. It's similar to 'inside'. I'm in a room.

So to help you remember these rules, try to think of a concert:

I'm at the front. The band is on the stage. And my friends are in the crowd.

And where are you right now?

用法總結(jié)

1. 我們用 “at” 來(lái)表示 “在具體的位置”。 

• I'm at work.
• I left my keys at home.

2. 我們用 “on” 來(lái)表示 “在物體的表面上”。

• I'm sitting on a chair.
• The pen is on the desk.

3. 我們用 “in” 來(lái)表示 “在立體空間內(nèi)”，在這種情況下，“in” 與 “inside” 用法相似。

• I'm in a room.
• The cat is in a box. 

4. 想象在一場(chǎng)演出中，不同人員的所處方位，記憶 “at”、“on” 和 “in” 在表 “位置” 時(shí)的用法：

• I'm at the front. The band is on the stage. And my friends are in the crowd.
