第三人称单数用has，其余用have.现在完成时的否定式直接在助动词后面加上not、疑问式是把助动词提到主语之前。
以study 为例，其否定式、疑问式和简单回答形式如下：（2）用法：1）现在完成时通常表示在说话之前已经完成的动作或存在的状态。
说话人强调的是该动作或状态对现在的结果或影响。
My daughter has just gone out. 我女儿刚出去。
I’m sure we’ve met before. 我肯定我们以前见过面。
She has arrived. 她到了。
2）表示持续到现在的动作或状态，往往和包括现在在内的表示一段时间的状语连用，如recently, already, just, lately, fo r…, since…,yet等。
如：I haven’t heard from her these days. 这些日子我没有收到她的信。
We haven’t seen you recently. 最近我们没有见到你。
They have been away for two years. 他们离开已经两年了。
She has been with us since Monday.★注意：a)since和for的区别since后接时间点，如1993，last term, yesterday, the time I got therefor后接一段时间，表示“长达多久”，如ten years, a while, two days等。
