小学英语语法：句型转换

英语语法之句型转换
一、改否定句
1. 表示某一否定意思。

句中一定有not。

2. 有四种情况：
(1)句中有be动词（am、is、are、was、were）
方法：直接在be动词后+ not
如：These are bananas. -------These aren’t bananas.
(2) 句中有情态动词（can, would, will, must, should, could等）
方法：直接在情态动词后加not
如：The boy can play football. ------- The boy can’t play football.
(3) 句中既没有be动词也没有情态动词，有行为动词
方法：在行为动词前加don’t，doesn’t，didn’t，动词还原。

如: They swim in summer. ------They don’t swim in summer.
He likes apples. ------ He doesn’t like apples.
Nancy watched TV last night. ------Nancy didn’t watch TV last night.
(4) 祈使句：表示请求或命令别人做某事或不要做某事。

方法：在动词前面加don’t

------ What does Su Hai get from her e-friend Anna in Hong Kong?
4.对划线部分提问的几种特殊句型：
(1) 划线部分是动词词组，划线部分要用do的适当形式来代替。

如：Su Hai gets an email from her e-friend Anna in Hong Kong.
------ What does Su Hai do in Hong Kong?
(2)对数量提问，无论数量是几，都要用How many +可数名词复数。

------ How many emails does Su Hai get from her e-friend Anna in Hong Kong?
(3)对主语提问的句子，找到疑问词，后面照抄。

如：Su Hai gets an email from her e-friend Anna in Hong Kong.
------ Who gets an email from her e-friend Anna in Hong Kong?
(4)对There be 的主语提问，what’s + 介词短语？
