1.I read English every day.
否定句是直接对动词进行否定.像这句话read否定要用do not（don't）,be的则用be not（isn't,aren't）
否定句：I don't read English every day.
一般疑问句是疑问句的一种.它是指用yes或no来回答的句子.其结构是：系动词be/助动词/情态动词＋主语＋其他成分?
一般疑问句：Do you read English every day?
(这儿通常没有问自己的,都是问其他人,因此人称要改一下)
肯定回答的格式是“Yes,主语（一般是代词）+系动词be/助动词/情态动词.”
肯定回答：Yes,I do.
否定回答的格式是“No,主语（一般是代词）+系动词be/助动词/情态动词+not （一般会有缩写,don't.isn't.etc）.”
否定回答：No,I don't.
对时间进行提问,用when,然后跟一般疑问句,原来句子的时间状语去掉.
提问：When do you read English?
下边几个就不细说了吧~\(≥▽≤)/~
2.She watches tv in the evening.
否定句：She doesn't watch TV in the evening.
(she是第三人称单数,要用does)
一般疑问：Does she watch TV in the evening?
肯定回答：Yes,she does.
否定回答：No,she doesn't.
提问：When does she watch TV?
3.We do our homework every day.
否定句：We don't do our homework every day.
一般疑问：Do you do your homework everyday?
(第一个do是助动词,第二个是do our homework的do,句子的谓语,和上边一个句子类似的改一下人称比较好)
肯定回答：Yes,we do.
否定回答：No,we don't.
提问：When do you do your homework?
4.They often play basketball.(often,写错了吧：）)
否定句：They don't often play basketball.
一般疑问：Do they often play basketball?
肯定回答：Yes,they do.
否定回答：No,they don't.
提问：When do they play basketball?
再补充：上边那位说How often是有道理的,不过你这儿说对“时间”提问么.
