小学英语必会基础知识--一般疑问句

 

          一般疑问句是小学乃至更高年级必须掌握的一个基本句型，其作用不言而喻，小学阶段包括陈述句变成一般疑问句，以及肯定和否定回答方法都是需要必须掌握的，接下来我对小学一般疑问句的相关知识加以小结，仅供参考！

一般疑问句：
一般疑问句也可称为 “yes ／ no questions”，因这种问句通常用yes ／ no来回答，相当于汉语中的“……吗？”其构成主要方式是：系动词be ＋主语＋其他成分  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．

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。
例：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。
例：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。
例：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．读法：一般疑问句一般读升调(↑)
5．一般疑问句有时也可以不用yes或 no 回答。
例：Are they in town now？
I think so.
May I sit here？
Certainly．
Does he like soccer？
Sorry I don't know．
