  • 考点名称:一般疑问句

    • 一般疑问句:
      是疑问句的一种。通常用yes,no来回答的疑问句叫做一般疑问句。口语中若无特殊含义,句末用升调。
      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 
      例如:
      Are you from Japan?   Yes, I am./No, I'm not.
      Do you live near your school? Yes, I do./No, I don't. 
      Can you speak French?  Yes, I can./No, I can't.

    • 一般疑问句的特性:
      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(↑)
      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。

    • 陈述句变为一般疑问句技巧:
      根据一般疑问句不同的家族,可以用不同的方法将陈述句变为相应的一般疑问句。
      1、第一家族:含be动词或情态动词的句子
      秘诀:一调二改三问号
      一调:即把句中的be或情态动词调到主语前;
      二改:改换主语称谓,即将句中的主语I\my \mines\we\our\ours等。第一人称分别改为相应的第二人称you\your\ yours等;
      三问号:句末的句号改为问号。如:
      Eg. I am an English teacher.    →    Are you an English teacher?
      Eg. We can speak English fluently.   →    Can you speak English fluently?

      2、第二家族:含行为动词(或称为实义动词)的句子
      秘诀:一加二改三问号
      一加:即在句首加助动词Do或Does;
      二改:1、把谓语动词改为原形;2、改换主语称谓(同第一家组);
      三问号:句末的句号改为问号。
      Eg. We read English every morning. → Do you read English every morning?
      Eg. Tom’s father listens to English on the radio every evening. →Does Tom’s father listen to English on the radio every evening?
      特别注意:对于第二家族一定要注意动词的还原,因为时态与数的变化已经体现在助动词上了。

      3、加强记忆口诀:
      肯变一,并不难,can 或be提在前;
      谓语若为行为动,do 或does句首用。
