Question

janewatchestvaftersupper(改为否定句)

Answer 1

Jane doesn't watchTV after supper.

分析：
句子变否定句的方法：
1 句中有动词be，情态动词，助动词时，变否定句直接在后面加NOT
2 实义动词 作谓语，要加相应的助动词don't / doesn't (一般现在时第三人称单数） / didn't (一般过去时），原来的动词要还原。
如
1) He is a worker . 他是一名工人。
He isn't a worker. 他不是工人。
2) Jim can swim . 吉姆会游泳。
Jim can't swim . 吉姆不会游泳。
3) Jane watches TV after supper . 简晚饭后看电视。
Jane doesn't watch TV after supper . 简晚饭后不看电视。
4） They go to school on foot . 他们步行上学。
They don't go to school on foot . 他们不是步行上学。
5） She bought a pen yesterday . 她昨天买了一支钢笔。
She didn't buy a pen yesterday . 她昨天没买一支钢笔。

Answer 2

【改变前】Jane watches TV after supper.
【改变后】Jane doesn't watch TV after supper.
【解析】该句为一般现在时，主语单数三人称，该为否定句用doesn't否定，将动词还原。
