一般過去時——過去做某事
A、構(gòu)成形式：主語+動詞的過去式+其他。
注意：沒有be動詞的否定句和疑問句中，用didn’t否定和用did提問后，動詞一定要用原形。
B、判斷依據(jù)：
(1)be動詞是was、were;
(2)動詞加ed;
(3)有表示過去的時間狀語，現(xiàn)在學(xué)過的常用的表示過去的時間狀語有：just now，a moment，yesterday，last week，last night，last weekend，last year，last month，three days ago，two weeks ago，five years ago…
C、句型變換：

Yes, I was. / No, I wasn’t.
They played many games yesterday.
