英语肯定句、否定句、一般疑
小学英语肯定句、否定句、一般疑问句和特殊疑问句的详解
肯定句，否定句，一般疑问句的用法
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。然后做出肯定回答和否定回答。如： I'm a student.→ Are you student?
Yes, I am. No , I’m not
We're watching TV．→ Are you watching TV？
Yes, we are. No, we aren’t.
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。然后做出肯定回答和否定回答。如：
He can swim now． →Can he swim now？
Yes, he can. No, he can’t.
The children may come with us→ May the children come with us？
Yes, they are. No, they aren’t.
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，(句子中没有be动词am , is , are.) 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？
Yes, I do. No, I don’t.
She wants to go to the movies.→ Does she want to go to the movies？ Yes, she does. No, she doesn’t.
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。
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
一般疑问句这种问句通常用yes ／ no来回答，相当于汉语中的“……吗？”其语序是：系动词be ／助动词／ 情态动词＋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．
