1、Unit3LanguageinuseModule2ExperiencesGrammar现在完成时(1)如果你想说“我已经看过某部电影,所以不想看了”、“某人曾经作过什么事情”等等,该如何表达呢?首先请看下面的句子:Ihaveseenthefilm.Idon’twanttoseeitagain.(2)Haveyoueverlookedatatravelbrochure?(3)IhavenevervisitedtheUSA.以上句子的谓语动词有一个共同的特点就是“have/has+动词的过去分词”,用于表示在以前的某个时间曾经做过
2、的、发生的事情,这种行为对目前有某种影响,如(1);还可以表示到目前为止曾经经历或没经历的事情,如(2)(3)。我们把这种时态称为“现在完成时”。现在完成时Presentperfect构成:1.肯定句现在完成时的肯定句式是“have(has)+过去分词”。注意:该句式中的have或has是助动词,has用于第三人称单数,其它人称一律用have。定义:表示过去发生或已经完成的某一动作对现在造成的影响或结果。Summary2.否定句:现在完成时的否定句式是“haven’t(hasn’t)+过去分词”。3.疑问句:现在完成时的一般疑问句
3、式是把助动词have或has提到主语之前。回答用Yes,…have(has)./No,…haven’t(hasn’t).连用时间状语:already,yet,ever,never,just,before,severaltimes等。动词过去分词的变化形式大部分与动词过去式形式相同,但是不规则动词的变化形式没有规律,需要记忆,比如:see-saw-seen;be-was,were-beeneat-ate-eaten;break-broke-brokengo-went-gone;take-took-takensend-sent-sen
