一般疑问句是疑问句的一种.它是指用yes（是）或no（否）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?通常回答为：肯定：Yes,+主语+提问的助动词.否定：No,+主语+提问的助动词+not.
注：
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.
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.
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.
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.
