LOOK is to direct your attention towards something. “Look” is intentional, and it is often used in this form: look + at + (object).
- Look at the sunset – it’s so beautiful!
- Look at that strange man.
- Look at the pictures I took on holiday.
- Don't look at the sun with naked eye.
- Look at me while I am speaking.
- He looked at his watch and told me the time.
- Don’t look at me like that, I didn't do anything wrong.
SEE is to perceive with your eyes, but it is not intentional (you don’t “try” to see, it just happens)
- I saw a car accident while driving home from work.
- Did you see that bird? – I wasn’t looking for it, it just appeared.
- I saw you driving to work today.
- Can you see my house over the cliff?
- Bats can see very well in the dark.
- See you tomorrow.
- You may not see much in dim light.
WATCH is to keep your eyes on something (usually something that is moving) for a long time. It is intentional.
- I’m watching TV.
- I watched the baseball game.
- All day long I just watched TV yesterday.
- I like watching the spectacular sun set every day.
- Please be quiet, I am trying to watch the world cup series.
- Do you like watching talk shows?
