〖语法全解〗
一般过去时：表示过去发生的动作或存在的状态。
一、动词过去式的词形变化
1. 规则变化可概括为：“直”、“去”、“双”、“改”四字诀。
① “直”—— 一般情况下，在动词原形后直接加ed：work-- worked ,clean--cleaned
② “去”—— 以不发音的e结尾的词，直接加d：live --lived
③ “双”—— 以重读闭音节(辅音+元音+辅音)结尾的词，双写最后的辅音字母+ed： stop--stopped
④ “改”—— 以辅音字母+y结尾的词，变y为i加ed：study—studied
(5) 不规则变化特殊记
★★★规则动词过去式-ed的发音:
1) 在以清辅音结尾的规则动词后, -ed读作/ t /。worked /wɜ:kt/
2) 在以浊辅音或原音结尾的规则动词后, -ed读作/d /。lived /livd / play /pleid /
3) 以/t/或/d/结尾的规则动词后, -ed读作/id /。 visited /'vizitid/
【练习】写出下列-ed的发音。
1. finished 5. helped 2. wanted 6. called 3. needed 7. enjoyed
4. shouted 8. moved
Keys：1. /t/ 2. 3./id/ 4. /id/ 5. /id/ 6. /t/ 7. /d/ 8. /d/ 9. /d/

二、句型：
1. 肯定句：谓语动词用过去式(没有人称和时态的变化);
eg: I joined the Solar Power Club yesterday.
I was ill yesterday.
2. 否定句：将谓语动词改为“didn't+动词原形”;含有be动词和情态动词的句子，直接在其后加“not”.
eg: I didn't join the Solar Power Club yesterday.
I was not ill yesterday.
3. 一般疑问句：在句首加助动词did，句中的动词也要改为原形。含有be动词和情态动词的句子，直接将be动词和情态动词提至句首。

Were you ill yesterday?

三、一般过时的用法

四、一般过去时的时间状语
一般来说，一般过去时都有明显的表示过去的时间状语。如：yesterday., last...,...ago, in 1998, just now等等。
eg: Your mother came here an hour ago.
