目前我们学过的在句子中做谓语的动词有两类：
1.be动词 am, is was are were 2.实意动词除了be动词以外，都是实意动词。 我们平常用的那些动词，例如，eat ,look .teach.see.hear.等
☆助动词dodid
do有两个词性，一个是助动词，做助动词的时候 没有词义，只是协助动词。
2.它也可以用来表示在过去某段时间里经常 发生的习惯性动作。 My faBiblioteka Baiduher often went to work by bus last year.When I was a child, I often listened to music.
一般过去时的句子里常常有一个意义 较具体的过去时间状语。 如：last night (week ,month , year , century , etc.) , yesterday , the day before yesterday , yesterday morning ( afternoon , evening ) , in 1999 , two hours ago ( one week ago , tree years ago , …)等等。
1. I was played computer yesterday. I played computer yesterday. 2. They were baked bread in the kitchen last Sunday. They baked bread in the kitchen last Sunday.
一般过去时句中谓语动词是实意动 词的时候，变成否定句和疑问句， 都要借助于助动词did, 否定句在助 动词did后面加not,疑问句用did来 提问 (注意：只要出现助动词，后 面动词一定要还原）例： She played computer last Sunday. She didn't play computer last Sunday. Did she play computer last Sunday?
一般过去时谓语动词的变化： 1.be动词变成was或were 2.实意动词变成过去式： (1)一般情况下，动词词尾加 -ed ，如： work ---worked play---played want----wanted (2)以不发音的 -e 结尾动词，动词词尾加 -d，如： live---lived move----moved taste---tasted hope---hoped (3)以辅音字母 + y结尾的动词，把-y变为-i 再加-ed， 如： study---studied copy---copied cry---cried carry---carried (4)以一个辅音字母结尾的重读闭音节动词，双写词尾 辅音字母，再加 -ed，如： stop ---stopped trip--tripped
一个是实意动词，表示“做”的意思，比如 do homework
否定句和疑问句
一般过去时句中谓语动词是be 动词的时候，否定句在be动词( 即:was或were)后加not，一般 疑问句把was或were调到句首。 例： It was hot yesterday. It wasn't hot yesterday. Was it hot yesterday?
一般过去时
1.用来描述在过去某个时候发生的动作或存 在的状态。 例： He was here yesterday. I got up at six thirty yesterday morning. My father was at work yesterday afternoon. Did you have a good time last summer?
清对清,浊对浊。元音后面还是浊,/t/、/d/后面发 /id/。其余后面常发浊。 1. 在轻辅音[p] [k] [f] [s] 等后加ed读轻辅音 /t/ ： asked cooked worked looked talked picked helped surfed 2. 在浊辅音[b] [g] [v] [z] [m]等及元音后加ed读浊 辅音/d/ ： lived listened closed opened watered 3. 在/t/ /d/ 之后读 /Id/ ： add --- added need --- needed shout --shouted wait --- waited want ---wanted played
