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