【知識結構】
（一）、Grammar
現在完成時
如果你想說“我已經看過某部電影，所以不想看了” “某人曾經做過什麼事情”等等，該如何表達呢？首先請看下面的句子：
(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.
以上句子的謂語動詞有一個共同的特點就是“have/has+動詞的過去分詞”, 用於表示在以前的某個時間曾經做過的、發生的事情，這種行為對目前有某種影響，如(1); 還可以表示到目前為止曾經經歷或沒經歷的事情，如(2)(3)。我們把這種時態稱為“現在完成時”。
● 定義：表示過去發生或已經完成的某一動作對現在造成的影響或結果。
構成：
● 1. 肯定句
“have（has）＋過去分詞”。
注意：該句式中的have或has是助動詞，has用於第三人稱單數，其他人稱一律用have。
● 2. 否定句：
“haven’t（hasn’t）＋過去分詞”。
● 3. 疑問句：
把助動詞 have或has提到主語之前。
回答用 Yes, …have (has). /No, …haven’t (hasn’t).
● 連用時間狀語：already, yet, ever, never, just, before, several times 等。
● 動詞過去分詞的變化形式大部分與動詞過去式形式相同，但是不規則動詞的變化形式沒有規律，需要記憶。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
