小学英语句型转换专项练习.doc

句型转换方法归纳
一、 改为否定句
1、 先找be动词或情态动词.假如有这些词, 直接在这些词后面加not, some 改成any, 其它照抄;
2、 假如句子中没有be动词或者是情态动词, 要在动词前面加don’t 、 doesn’t或者是didn’t, some 改成any, 其它部分照抄。
(1)首先判定句子时态, 假如句子是过去时, 则要在动词前面加didn’t, 这个动词用原形;
(2)假如句子不是过去时, 则判定主语是否为第三人称单数, 如是, 要在动词前面前加doesn’t, 这个动词改为原形, 其她情况均要在句子动词前面加don’t。
二、 改为通常疑问句（some 改成any, I改成you, my改成your, 句号改成问号, 其它照抄）

2、 假如句子中没有be动词或者是情态动词, 要在句子最前面加助动词 do 、 does或者是did, 后面动词用原形。
(1)首先判定句子时态, 假如句子是过去时, 则要在句子最前面加Did;
(2)假如句子不是过去时, 则判定主语是否为第三人称单数, 如是, 要在句子最前面加Does, 其她情况均要在句子最前面加Do
