英语怎样做否定句,一般疑问句,对划线部分提问,有怎样的技巧,举几个例子
把否定句,一般疑问句,对划线部分提问,给几个例子说明一下,还有怎样做这种题的技巧

一、否定句
1.主语+be动词+表语结构
变否定句,直接在be动词后面加个not就可以了.
Mr. White is a very good teacher.-->Mr. White is not a very good teacher.
2.主语+动词+其他
当此句为一般现在时,在动词之前加don't或doesn't（第三人称单数形式）,并将动词变为原形就可以了
He loves playing football with his friends.-->He doesn't love playing football with his friends.
当此句为过去时,在动词之前加didn't,并且把动词变为原形
Tom's sister graduated from high school last year.-->Tom's sister didn't graduate from high school last year.
3.主语+情态动词+动词+其他
在情态动词后面加not就可以了
I can drive a car.-->I cannot drive a car.
4.主语+have/has+动词过去分词+其他
在have/has后面加not就可以了
The students have done their homework.-->The students have not done their homework.
二、一般疑问句
1.主语+be动词+表语结构
变一般疑问句,把be动词提前,句子就变成 be动词+主语+表语结构?
Mr. White is a very good teacher.-->Is Mr. White a very good teacher?
2.主语+动词+其他
当句子为一般现在时,在句首加do或does,并且把动词变为原形,句子变成 Do/Does+主语+动词原形+其他?
He loves playing football with his friends.-->Does he love playing football with his friends?
句子为一般过去时,在句首加did,句子变成 Did+主语+动词+其他?
Tom's sister graduated from high school last year.-->Did Tom's sister graduate from high school last year?
3.主语+情态动词+动词+其他
将情态动词提前,句子变成 情态动词+主语+动词原形+其他?
I can drive a car.-->Can you drive a car?
4.主语+have/has+动词过去分词+其他
将have/has提前,句子变成have/has+主语+动词过去分词+其他
The students have done their homework.-->Have the students done their homework?
三、对划线部分提问
先找出划线部分在句子中所占得成分,找到对应的疑问词,将疑问词写在句首,再将原句变成一般疑问句,却掉划线的部分,写在疑问词后面就可以了.
Tom bought a new computer from the store yesterday.
若划线部分为Tom,Tom 是个人,且作主语,则疑问词应选Who, 此句应该为 Who bought a new computer from the store yesterday?
若划线部分为a new computer, 划线部分为物,则疑问词为what,此句应为 What did Tom buy from the store yesterday?
若划线部分为from the store,则疑问词应为Where,表示地点,此句应为 Where did Tom buy a new computer yesterday?
若划线部分为yesterday,则疑问词为When,表示时间,此句应为 When did Tom buy a new computer from the store?
