Review the past simple tense.2. Homework附：一般过去时口诀：动词一般过去时，表示过去发生的事；be用was或用were, have,has变had；谓语动词过去式，过去时间作标志；一般动词加-ed，若是特殊得硬记。否定句很简单，主语之后didnt添； 疑问句也不难，did放在主语前； 不含be动词时如果谓语之前有did，谓语动词需还原；动词若是was,were,否定就把not添。 含be动时疑问句也不难，要把was，were放在主语前。一般过去时练习题I.请用正确动词形式填空1.      He lived (live) in Wuxi two years ago.2.      The cat ate (eat) a bird last night.3.      We had (have) a party last Halloween.4.      Nancy picked (pick) up oranges on the farm last week.5.      I made (make) a model ship with Mike yesterday.6.      They played (play) chess in the classroom last PE lesson.7.      My mother cooked (cook) a nice food last Spring Festival.8.      The girls danced (dance) at the party last night.9.      I watched (watch) a cartoon on Saturday last week.10. _Did_ you _visit_ (visit) your relatives last Spring Festival?11. _Did_ he _fly_ (fly) a kite on Sunday?
