(改为一般疑问)______ he _____ any meat in the fridge 牛刀小试句型转换He read some books in English.( 改为否定句)He _______ _______ _______ books in English.思路点拨:显然,原句主语是he,谓语read是read读的过去式,需借助did构成过去时态。根据句意和英文提示,可知填(1).didn' t (2)read (3)any牛刀小试She did some hard work last week.(改为否定句)She didn't _____ any hardwork last week.思路点拨:根据原句是过去时态,变否定句借助助动词didn’t,谓语动词变成原形,故填do。牛刀小试Liza was late for school because she was ill. (对划线部分提问)______ _______ Lisa late for school 思路点拨:句意:Liza上学迟到了,因为她生病了。本题要求我们对划线的部分进行提问,原句中划线的部分是because引导的一个原因状语从句,故疑问词应该是why,再将原来的was提前。答案: Why; was03 动词变化规则变化1.一般情况下,直接在词尾加ed2.以不发音的字母e结尾的动词加-d3.辅音元辅结尾的重读闭音节词,先双写这个辅音字母,再加ed .play —playeddrop —dropped4.以辅音字母加y 结尾的词,先改 y为 i,再加edstudy —studiedlive —lived原形 过去式 原形 过去式am/is/are 是 was/was/were eat 吃 atebecome 变成 became fall 摔倒 fellbring带来 brought feel 感觉 feltbuy 买 bought fly 飞 flewcan 能够 could get 得到 gotcome 来 came give 给 gavecut 切,砍 cut have/has 有,患病 haddo/does 做 did hurt 受伤 hurtdraw 画画 drew keep 保持 keptdrive 驾驶 drove make 制作 made不规则变化表原形 过去式 原形 过去式put 放 put go 去 wentread 阅读 read ride 骑 rodesay 说 said take 拍照,拿 tooksee 看见 sawsing 唱歌 sangsleep 睡觉 sleptwear 穿 worewill 将 wouldwrite 写 wrotethink 想 thought不规则变化表04 强化训练一、写出下列动词的过去式。1. is 2. visit 3. visit 4. study 5. run 6. swim 7. sleep 8. write 9. love 10. stop waslivedransleptlovedvisitedstudiedswamwrotestopped二、用所给动词的适当形式填空1.Tom and Mary ___________ (come) to China last month.2.Mike ____________(not go) to bed until 12 o’clock last night.
