      2.疑问副词用在句首。

    • 疑问代词与疑问副词的区别:
      1. 疑问代词做对陈述句的主语,宾语或定语提问,即做句子的主语,宾语或定语,如what, who/ whom, whose.
      eg. Who is talking ? What can you see?
      Whose shirt is this?
      2.疑问副词对时间,地点,方式等状语提问,如when, where, how 等.
      eg. When is your birthday? Where are you going?
      How do you know?
      常见的疑问代词:what  who  which  whom(只做宾语)
      疑问副词:how  where  when
      还有whether是疑问连接词。

    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?
