look、watch 和see 的区别:1. 从词义上看:look 通常表示主动地、有意识地“看”,侧重指看的行为;see 通常指看的客观结果,即“看见”;watch 也指有意识地看,但往往指仔细地盯着看事物的变化。如:I looked hard but saw nothing. 我认真看,但什么也没看见。The cat is watching the mouse. 猫儿盯着老鼠。If you watch (look) carefully, you will see how I do it.你要是仔细观察(看),你就能看出我是怎样做的。2. 从是否及物来看:(1) look 通常为不及物动词,若需后接宾语,其后须接介词(如at, for, after 等)。如:Look at the blackboard. 看黑板。He is looking for his wallet. 他在找钱包。有时 look 也用作及物动词,表示“仔细打量”。如:He looked me up and down. 他上下打量我。
