【探究· 导学】
交流与探究
如果你想说“我已经看过某部电影，所以不想看了” “某人曾经做过什么事情”等等，该如何表达呢？首先请看下面的句子：
(1)I have seen the film. I don’t want to see it again.
(2) Have you ever read a travel brochure
(3) I have never visited the USA.
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 Present perfect 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。
构成：1. 肯定句 “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，其他人称一律用have。
小结：现在完成时
2. 否定句：
“haven’t（hasn’t）＋过去分词”。
3. 疑问句：
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, several times 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。例如： see-saw-seen;
eat-ate-eaten; break-broke-broken
go-went-gone; take-took-taken
send-sent-sent; find-found-found
make-made-made; have-had-had
你学会了吗？
