VOA一分钟英语：怎么区分 see，look，watch？

动词 “see、look” 和 “watch” 都可以用来描述用眼睛 “看” 的动作，但它们所描述的 “看” 的方式和对象是不同的。动词 “see” 表示 “看见”；动词 “look” 可以指让他人 “看过来”；动词 “watch” 表示 “正在观看”。
 
Hello, I'm Sam from BBC Learning English. And in this episode, we're going to look at the differences between see, watch and look. All three are verbs and all three involve using your eyes.
See can have many non-literal meanings, but its basic meaning is 'to have the ability to use your eyes'. I can't see anything! Or it can mean 'to notice something with your eyes'. Did you see the full moon last night? It was huge!
To look means 'to turn your eyes towards something so that you can see it'. They said that if I look carefully at the painting, I can see a flower.
And watch is to 'look at something for a period of time' – really looking carefully. Right now, you are watching this video and paying very close attention, I'm sure.
