have a look at 是名词化用法吗

We went to have a look at him.

We went to have looked at him.

老师，两句子有什么不相同，a look at是抽象名词吗，这里的介词与动词组成一个短语动词了，有have a listen to him,have a take about him,have a tell abou hime,have a think about him...have a swim,等吗，这种用法有什么不同，单词与词组有名词，动词等词性，都可以这样用吗？

look at ：表示“看”的动词可以持续。

have a look at：只表示一次性动作，“看一下，看一眼”。不表示“持续性”。

【语法知识】具有动作意义的名词，在与动词have,take,give,let out 等构成短语表示一种短暂性、一次性的动作，此时，名词前的不定冠词不可缺少。

have a look 看一看 have a walk 散步　 have a break 休息一下

have a try 试一试 have a swim 游泳 take a rest 休息一下

give a laugh 大笑 give a smile 微笑

give a shout 大喊 make a choice 作选择

let out a cry 发出喊叫 let out a sigh 叹口气

(1)We went to have a look at him.（正确）(look为名词用法）

=We went to take a look at him.

=We went to look at him

备注：表示看望某人，最好用visit/see,如果拜访某人drop in on sb

We went to see him.

We went to visit him

We went to drop in on him

I'll drop in on you when I have time.

有空我来看你.

It's improper to drop in on him so casually.

这样冒冒失失去找他可不好.

(2)We went to have looked at him.（错误）

不定式作目的状语，属于将来动作，即不定式动作是在谓语动词动作之后发生的，因此不可以使用不定式完成式作目的状语。不定式完成式表示在谓语动词动作之前发生。
