拓展：
一、肯定句变否定句的方法：
1、句中有动词be(am ,is ,are ,was , were ),情态动词时，助动词(完成时态中的have /has )，变否定句直接在这些词的后面加not;
2、行为动词作谓语时的否定句要加助动词don't / doesn't (第三人称单数）/ didn't (一般过去时），后面的动词要用原形，句在有some 时要改为any 。
如：
1).He is a student . -> He isn't / is not a student.
2).We are students . -> We aren't / are not students.
3).I will go to Beijing tomorrow. -> I won't / will not go to Beijing tomorrow.
4).He can speak English . -> He can't / can not speak English .
5).She has finished her homework . -> She hasn't / has not finished her homework.
6).He goes to school on foot . -> He doesn't go to school on foot .
7).They worked hard last term .-> They didn't worked hard last term .
8).There are some flowers in the room .-> There aren't/ are not any flowers in the room.
二、陈述句变一般疑问句的方法：
1、句中有动词be(am ,is ,are ,was , were ),情态动词时，助动词（完成时态中的have / has ），变一般疑问句直接在这些词提到句子前面，句末加问号。肯定回答是：Yes,... (am /is / are / was /were)/ 情态动词/have / has.
否定回答：No, ... ((am not /isn't / aren't / wasn't /weren't )/ 情态动词 not /haven't / hasn't.
2、行为动词作谓语时的一般疑问句要加助动词do / does (第三人称单数）/ did (一般过去时），后面的动词要用原形，句在有some 时要改为any 。肯定回答：Yes ,... do/does /did .
