句型转换的方法
一、改成否定句和一般疑问句 Be句型:
1、改成否定句;在Be动词后加not。am not, is not = isn’t , are not = aren’t。 例如;He is a student.(改成否定句)He isn’t a student. 2、改成一般疑问句:将Be动词提前,主语放后。 例如;He is a student.(改成一般疑问句)Is he a student?
Do句型: 1、改成否定句;在主语后加don’t或doesn’t。※如果主语是单数第三人称,变成否定句时,谓语动词单3形式要还原成原形。
例如;I usually go to school at 7:00.(改成否定句)I don’t usually go to school at 7:00.
He goes to work by bus.(改成否定句)He doesn’t go to work by bus.
2、改成一般疑问句;在主语前加Do或Does。※如果主语是单数第三人称,变成一般疑问句时,谓语动词单3形式也要还原成原形。 例如;I usually go to school at 7:00.(改成一般疑问句)Do I / you usually go to school at 7:00?
He goes to work by bus.(改成一般疑问句)Does he go to work by bus?
Can句型:
1、改成否定句;将can变成can’t。
例如;You can clean the room.(改成否定句)You can’t clean the room. 2、改成一般疑问句:将can提前,主语放后。
例如:You can clean the room.(改成一般疑问句)Can you clean the room? There be句型:
1、改成否定句:在is或are后加not。※变成否定句时,some要变成any。 例如:There is a cat under the tree.(改成否定句)There isn’t a cat under the tree.
There are some books on the desk.(改成否定句)There aren’t any books on the desk.
2、改成一般疑问句:将Be动词提前,there放后。※变成一般疑问句时,some要变成any。
例如:There is a cat under the tree.(改成一般疑问句)Is there a cat under the tree?
There are some books on the desk.(改成一般疑问句)Are there any books on the desk?
二、一般疑问句的肯定和否定回答。 Be句型:
肯定回答:Yes, 主语 + be. 否定回答:No, 主语 + be not. 例如:Is he a student? (做出肯定和否定回答)Yes, he is. No, he isn’t. Do句型:
(1)肯定回答;Yes, 主语 + do. 否定回答;No, 主语 + don’t.
例如:Do you go to school at 7:00?(做出肯定和否定回答)Yes, I do. No, I don’t.
(2)当主语是单数第三人称时,肯定回答:Yes, 主语 + does. 否定回答:No, 主语 + doesn’t.
例如:Does she go to work by bike?(作出肯定和否定回答)Yes, she does. No, she doesn’t. Can句型:
肯定回答:Yes, 主语 + can. 否定回答:No, 主语 + can’t. 例如;Can they clean the classroom?(做出肯定和否定回答)Yes, they can. No, they can’t. There be句型:
肯定回答:Yes, there be. 否定回答;No, there be not. 例如:Are there any books on the desk?(做出肯定和否定回答)Yes, there are. No, there aren’t.
三、单复数互变
1、单数变复数:
⑴ this(这个) 变 these(这些) that(那个)变those(那些) ⑵ be动词变成复数形式 ⑶ 去掉a / an ⑷ 名词变复数
2、复数变单数:
⑴ these(这些)变this(这个) those(那些)变that(那个) ⑵ be动词变成单数形式 ⑶ 加上a / an ⑷ 名词变单数
