Have是英语中最常用的动词之一.它具有双重作用──既可用作助动词,又可用作一般动词.现结合初中英语课本简述如下：一、作助动词,帮助构成各种完成时态：I have just washed my clothes.我刚洗完衣服.When I got there,the train had already left.我到时,火车已经开走了.助动词have和has常可分别缩略为-’ve,-’s.所以I’ve=I have,We’ve=We have,He’s=He has,It’s=It has.但是,当have(has)处于句末时,不能用缩略形式.如：──Have you finished your homework?──Yes,I have.(不能用yes,I’ve.)二、作一般动词,主要有以下几种用法：1.表示“有”；.如：It has no eyes and no ears.它既无眼又无耳.当表示“有”时,have的疑问式和否定式有两种构成方法.第一种方法是不用助动词.把have提到主语前面构成疑问式,在have后加not构成否定式.如：Has Mary any story-books?玛丽有故事书吗?I haven’t any paper.我没有纸.第二种方法是用助动词do构成其疑问式和否定式.如：Do you have any tea here? 你这儿有茶吗?I don’t have a ruler. 我没有尺子.英国人多用第一种方法,美国人多用第二种方法.在两种方法都正确的情况下,应当注意,用哪种形式提问,必须用同样的形式回答.如：A：Have you an eraser?B：Yes,I have.(No,I haven’t.)A：Do you have an eraser?B：Yes,I do.(No,I don’t.)表示“有”时,have不能用进行时.如不能说：I’m having a bike.(×)在口语中,人们常用have got来代替have表示“有”.如：He has got a car.他有一辆车.Have you got a knife? 你有小刀吗?2.和具有动作含义的名词连用.如：Let me have a look.让我看看.We’re going to have a swim in the lake.我们打算在湖中游泳.这样用时,have只表示动作,不表示什么意义,动作的实际内容是其后边的名词所包含的.所以：to have a look=to lookto have a swim=to swimto have a rest=to rest不过,用“have+名词”的形式往往含有“一次”“一会儿”等意思.3.和其他各词连用,表示“上(课)”“吃(饭)”“开(会)”等.如：We have breakfast in the morning.我们早上吃早饭.What lessons did he have yesterday?昨天他上什么课了?They are having a meeting.他们正在开会
