介词 “at、on” 和 “in” 都可以用来表示人或事物所在的位置或地点。其中,哪个词表示 “在物体的表面上”?哪个指 “在立体空间内”?看视频,听主持人 Sam 讲解 “at、on” 和 “in” 在表示位置时各自的用法。
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?
1 我们用 “at” 来表示 “在具体的位置”。
I'm at work.
I left my keys at home.
2 我们用 “on” 来表示 “在物体的表面上”。
I'm sitting on a chair.
The pen is on the desk.
3 我们用 “in” 来表示 “在立体空间内”,在这种情况下,“in” 与 “inside” 用法相似。
I'm in a room.
The cat is in a box.
4 想象在一场演出中,不同人员的所处方位,记忆 “at”、“on” 和 “in” 在表 “位置” 时的用法:
I'm at the front. The band is on the stage. And my friends are in the crowd.
