解析：
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.
　　如:
　　Are you from Japan﹖
　　Yes I am． ／ No I'm not．
　　Is her sister doing her homework now﹖
　　Yes she is． ／ No she isn't．
　　Does he work in a bank﹖
　　Yes he does． ／ No he doesn't．
　　Do you live near your school﹖
　　Yes I do． ／ No I don't．
　　Can you speak French﹖
　　Yes I can． ／ No I can't．
　　May I go home now﹖
　　Yes you may． ／ No you mustn't．
注意：
　　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 1﹖
　　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(↑) 6.一般疑问句的第一单词总是虚词,读的时候要读轻声.
　　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．
