15、表示过去经常反复发生的动作，常和often, always等频率副词连用。例如：I saw him in the street yesterday. 昨天我在街上看见他了。Li Mei always went to school on foot last year. 去年李梅总是步行上学。一般过去时的构成我们主要来学习谓语动词为实义动词的一般过去时的构成。动词过去式的构成：(1)规则动词过去式的构成有四条规则：一般在动词原形末尾直接加上-ed。如：look-looked。以不发音的字母e结尾的动词，去e再加-ed。如：live-lived。末尾只有一个辅音字母的重读闭音节，先双写这个辅音字母，

16、再加-ed。如：stop-stopped。末尾是辅音字母+y结尾的动词，先变y为i，然后再加-ed。如：study-studied。(2)不规则动词的过去式需特殊记忆。如：am(is)-was, are-were, go-went, come-came, take-took, have (has)-had等。 一般过去时的几种句型肯定句结构为：主语+动词的过去式+其它。如：He went to the toy store yesterday. 他昨天去玩具店了。否定句结构为：主语+did not (didnt)+动词原形+其它。如：He didnt go to the toy store ye

17、sterday. 他昨天没去玩具店。一般过去时的一般疑问句的构成：Did+主语动词原形其它？如：1) -Did you go to Beijing last week?-Yes, we did. (No, we didnt.)2) -Did you meet the businessman before?-No, I didnt. (Yes, I did.)一般过去时的特殊疑问句的构成：疑问词did+主语动词原形其它？如：1) -What did you do last night?-I did my homework.2) -Where did you go last week?-I wen

18、t to Shanghai with my parents.一般过去时口诀一般过去时并不难，表示过去动作、状态记心间。动词要用过去式，时间状语句末站。否定句很简单，didnt 站在动词原形前，其它部分不要变。一般疑问句也好变，did放在句子前，主语、动词原形、其它部分依次站。特殊疑问句也简单，疑问词加一般疑问句记心间。最后一条请注意，动词过去式要牢记。典型例题操练：1.I _ (watch) a cartoon on Saturday. 2. Her father _(read) a newspaper last night. 3. We _ to zoo yesterday, we _ to

19、 the park. (go) 4. _ you _ (visit) your relatives last Spring Festival? 5. _ he _(fly) a kite on Sunday? Yes, he _. 6. Gao Shan _(put) up the picture last night. 7.
