look at ,look,have a look的区别

答案

look at ,look,have a look表示“看”时的区别如下：
1.look at是词组,at是介词,所以后面接名词、代词宾格或V-ing形式,例如：
Don't look at me like that.
别像那样看着我!
2.look是单词,一般常用于现在进行时且放在句首,例如：
Look!The girl is singing under the tree.
看!那个女孩正在树下唱歌!
3.have a look是词组,其中的look是名词（在以上两个中是动词）,其后一般常接at,例如：
——May I have a look at your new dictionary?
——Sure.
——我可以看一下你的新字典吗?
——当然（可以）.
