they had to work for the boss day and night.改为一般疑问句怎么改?
具体讲讲方法,还有遇到其他的一般疑问句怎么改?
一般疑问句是疑问句的一种.它是指用yes或no来回答的句子.其结构是:系动词be/助动词/情态动词+主语+其他成分?
1.将陈述句变为一般疑问句时,如句中有be 动词(am is are …)时,可直接将它们提至主语前.如主语为第一人称,应将其改为第二人称.如:I'm in Class 2Grade 1. → Are you in Class 2Grade We're watching TV. → Are you watching TV?2.陈述句中有情态动词(can may must …)时,也可直接将它们提至主语前,即可成为一般疑问句.如:He can swim now. → Can he swim now?The children may come with us. → May the children come with us?3.陈述句中只有一个实义动词作谓语且其时态为一般现在时,变为一般疑问句时要在句首加do或does 主语后的实义动词用原形.如:I like these animals. → Do you like these animals?She wants to go to the movies. → Does she want to go to the movies?4.一般疑问句一般读升调(↑) 5.一般疑问句有时不用yes或 no 回答.如:Are they in town now?I think so.May I sit here?Certainly. Does he like soccer?Sorry I don't know. 6.一般疑问句的第一单词总是虚词,读的时候要读轻声.
