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
1. 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

★变疑问句三步骤：将be动词移到句首，首字母大写，句号变问号。
Is the girl very beautiful?

★变否定句在be动词后面加not
The girl is not very beautiful.
Tim and Jack are not students.
★肯定回答及否定回答

（2）不含有be动词的句子，即含有一般动词的句子
第三人称单数及单数名词

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：有了助动词的帮助，句中动词变回原形！

★肯定回答及否定回答：
Yes, she does. No, she doesn’t
