  小学英语语法总结:一般现在时

  英语中的时态一共有八种,它们是:一般现在时、现在进行时、一般过去时、现在完成时、一般将来时、过去进行时、过去完成时、过去将来时。

  今天我们所要讲的就是第一种: 一般现在时——表示一般性,经常性的动作或一般性事实。

  1、含有be动词的句子

  He is a teacher.

  The girl is very beautiful.

  Tim and Jack are students.

  ★变疑问句将be动词移到句首

  Is he a teacher?

  Is the girl very beautiful?

  Are Tim and Jack students?

  ★变否定句在be动词后面加not

  He is not a teacher.

  The girl is not very beautiful.

  Tim and Jack are not students.

  ★肯定回答及否定回答

  Yes, he is. / No, he is not.

  Yes, she is. / No, she is not.

  Yes, they are. / No, they are not.

  2、不含有be动词的句子,即含有一般动词的句子。

  (1)第三人称单数及单数名词

  He likes books.

  She likes him.

  The dog likes bones.

  ★变疑问句在句首加does, 动词变为原型

  Does he like books?

  Does she like him?

  Does the dog like bones?

  ★变否定句在主语及动词之间加doesn't, 动词变为原型,原句中的动词不再有第三人称变化。

  He doesn't like books.

  She doesn't like him.

  The dog doesn't like bones.

  ★肯定回答及否定回答:

  Yes, he does. / No, he doesn't.

  Yes, she does. / No, she doesn't

  注意:第三人称单数形式一般在动词后面加S,不要和名词复数混淆,变否定句或疑问句时名词复数没有任何变化。

  (2)其他人称及复数名词

  I want to have a bath.
