look (at)
Look：注视，专注看（强调专注）；常常还用来提醒对方注意某个细节。例如：
- Look! It's snowing!
- 快看啊！下雪了！
- Look at this photo! Isn't it beautiful?
- 快看这个照片，很漂亮不是吗？
- I'm looking but I don't see it.
- 我在努力瞧，就是看不见它啊。
When we use look with an object, we say look at object
Look后要跟宾语，后面加at就可以了。
例如：
- John looked at Mary.
- 约翰注视了玛丽。
See：看见，看到（强调结果）；详解：表示某个事物已映入眼帘，或许都不需思考，睁眼就可见。
例如：
- I can see a cloud in the sky.
- 我可以看见天上的云朵。
- I suddenly saw a bird fly in front of me.
- 我突然看见一只鸟从我面前飞过。
- Didn't you see Ram? He was waving at you.
- 你看见Ram了吗？他刚在向你挥手。
Watch：观看，观察；详解：需要主动积极看，看的东西往往是要移动或改变的，而不是一直静止的事物。
例如：
- I like watching motor racing on TV.
- 我喜欢在电视上看赛车比赛
- If you watch that egg for long enough you'll see it hatch.
- 如果你观察那个鸡蛋时间够长，你会看到它孵化。
watch or see for movies, concerts, TV etc?
Watch或see都可搭配电影，音乐会，电视等对象吗？
In general, we use see forpublic performances and watch for television at home.
通常，我们用see搭配公开的表演，用watch表达在家看电视。
例如：
- We're going to see Johnny Depp's latest movie at the cinema tonight.
- 今晚我们要去电影院看约翰尼德普的最新电影。
- Did you ever see Michael Jackson live on stage?
