1、将疑问句中的肯定词改为否定词,或将否定词改为肯定词。

2、将反疑问句中的疑问语气词(怎、怎么、难道等)去掉。

3、将句末的疑问助词(呢、吗等)去掉,问号改为句号基本概念:陈述句是陈述一个事实或者说话人的看法。它包括肯定句和否定句两种。陈述句在书写时句末用句号,在朗读时用降调。疑问句是用来提问的句子,句末用问号。疑问句分为一般疑问句,特殊疑问句,选择疑问句和反义疑问句。

二、基本分类陈述句 肯定句 疑问句 一般疑问句特殊疑问句选择疑问句否定句 反义疑问句三、用法详解1、否定句1)一看句中是否有be 动词(am,is are,was,were),如果有 在其后加 not, 并把原句中的some改为any。例如:She is reading a book.---She is not reading a book.There are some apples on the tree.—There are not any (=no ) apples on the tree.2)二看句中是否有情态动词:(can ,could, may, must, will, would, should等)变化如同一中说,not 仍然放在后。例如: I can ride a bike.---I can not (=can’t) ride a book.We will hold a sports meeting next Sunday.----We will not (=won’t) hold a sports meeting next Sunday.3)三看句中是否有助动词:(have, has, had),变化如同前两说,not仍然放其后。例如:We have finished the task.----We haven’t finished the task.4)四变否定却看无,句中只有行为动(词),要提助动来完成。(don’t, doesn’t, didn’t)例如:

(1)I want a new bike.--I don’t want a new bike.(2)He wrote a letter to his pen-friend yesterday.--He didn’t write a letter to his pen-friend yesterday.(3)She always takes good care of her patients. --She doesn’t always take good care of her patients.当借助doesn’t和 didn’t 构成否定后,行为动词要还原为原形。

2、一般疑问句1)一看句中有无be (am, is, are, was, were) 只需提前就可以。例如: (1) She was a doctor five years ago.----- Was she a doctor five years ago?(2) I am reading a book.---Are you reading a book?2)二看句中谁当家,情态动词也最佳,提到句首不用问,例句强化说明它:例如: (1) They can climb up the high mountain.-----Can they climb up the high mountain?(2) I must finish my work this afternoon.----Must you finish your work this afternoon?3)三看助动(have has had)存在否,放在句首别疑它:例如: (1) The Greens have visited China already.---- Have the Greens visited China yet?4)四若不见以上三,句首加上Do, Does, Did莫等闲,再想特例全会变:例如: (1) They watch TV every night.--- Do they watch TV every night?(2) We had a big dinner just now.---Did you have a big dinner just now.(3) Her sister likes dancing.---Does her sister like dancing?当把助动词does和 did提前构成疑问后,行为动词要还原为原形。

3、特殊疑问句1)构 成:疑问词+一般疑问句2)疑问词:what(什么), who(谁), whose(谁的), which(哪个),when(何时), where(哪里), why(为何),how(怎样),how long(多久,多长时间),how far(多远),how often(多久一次),how soon(多快,多久以后),how many(问数量-可数名词),how much(问价钱;问数量-不可数名词),how old(问年龄)等。

3)解题步骤: step1:根据划线部分确定疑问词;step2:将句子变作一般疑问句;step3:去划线部分加问号。

4、选择疑问句1)构成: 一般疑问句+or+另一个备选对象Did you stay at home or at school yesterday?特殊疑问句+or+另一个备选对象Which would you like best, English, Chinese or Math?2)回 both/all/Noneeither/either
