I watch TV on weekends和They cleaned their classroom yesterday.改成一般疑问句要有说明(⊙o⊙)哦,如果有,赏分在加(⊙o⊙)哦

Do you watch TV on weekends?
Did they clean their classroom yesterday?
很高兴为你解答！
老师祝你学习进步！
请及时采纳哦！多谢你的问题！^_^

1. When do you usually watch TV?（这是问行为习惯的）
2. When did they cleaned classroom?

改成一般疑问句 的一般方法：

1.对于助动词、情态动词、be动词作谓语的，掉换主谓位置。
2.对于实意动词作谓语的，动词原型借助do，三人称单数借助does，过去式借助did，加在句首，再把谓语改为动词原型。
1.Do you watch TV on weekends?
2.Did they clean their classroom yesterday?

Am l watch TV on weekends?
Did they cleam their classroom yesterday?

第一个do you watch tv on weekends?
第二个did they clean their classroom yesterday?
ok加分吧

一般疑问句就是实意动词最谓语由　do／does／did这类词来引导
还有就是　助动词，情态动词，be动词的，直接提前发问
1．　do　you　watch　Tv　on　weekends？
2．　Did　they　clean　their　classroom　yesterday？
希望对你有帮助哦～
