    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   Yes, it does. / No, it 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.   We have some meat.   The students like smart teachers.   ★变疑问句在句首加do   Do you want to have a bath?   Do we have any meat?   Do the students like smart teachers?   ★变否定句在主语和动词之间加don't.   You don't want to have a bath.   We don't have any meat.   The students don't like smart teachers.   ★肯定回答及否定回答   Yes, I do. / No, I don't.   Yes, we do. / No, we don't   Yes, they do. / No, they don't.
