句型变换·陈述句变疑问句

1. 变成一般疑问句

将陈述句变成一般疑问句,要根据陈述句中的谓语动词及其时态确定疑问形式。其句型特点一般是:助动词或情态动词 + 主语 + 谓语 + 动词 + 其他?如:

The policeman told the boys not to play football in the street.

________ the policeman ________ the boys not to play football in the street?

答案:Did, tell

2. 变成特殊疑问句

将陈述句变成特殊疑问句时,常用的方法是“一选,二移,三变,四代”。

“一选”就是选择疑问词,被选择的疑问代词有:what, which, who, whose;疑问副词有:where, when, why, how;疑问副词词组有:how long, how often, how soon, how far, how many, how much, how old等。

“二移”就是把be动词,助动词或情态动词移到句首。

“三变”就是将原句中第一个单词的首字母改为小写(专有名词除外),将some, something等改为any, anything等,将句号改为问号。

四代就是将选好的特殊疑问词替代划线部分。如:

At the age of three, David weighed 20 kilos. (就划线部分提问)

________ did David weigh at the age of three?

答案:How much

3. 变成选择疑问句

将陈述句变成一般疑问句,在问号前加上“or + 所给的被选择部分”。如:

Most young men like popular music. (用 rock music 改为选择疑问句)

________ most young men like popular music ________ rock music?

答案:Do, or
