据专家权威分析，试题“将下列句子改成否定句和一般疑问句。1. Mary is having supper ..”主要考查你对  一般疑问句，主谓一致  等考点的理解。关于这些考点的“档案”如下：

一般疑问句主谓一致

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。

考点名称：主谓一致

• 英语中的一致主要包括主语和谓语在人称和数上的一致、时态一致、名词和其代词的一致。
  主语和谓语保持一致叫主谓一致，即谓语动词的形式必须随着主语单、复数形式的变化而变化。

• 主谓一致原则:
  1、语法上的一致
  所谓语法一致原则，即主语和谓语的语法形式在人称和数上取得一致。
