教你如何让肯定句变否定句、一般疑问句和特殊疑问句

例如：I play football. I don't play football. He plays football. He doesn't play football I played football. I didn't play football 如何变一般疑问句：（1）句子中有be, can, will的,把be , can , will 提前,I 通常变成you.例如：He is tall. Is he tall?I can swim. Can you swim?They will go to the park. Will they go to the park? (2) 句子中没有be, can, will的,在句子前面加do, does, did.原形：do；第三人称单数：does； 过去式：did.注意,加上do,does,did 后,动词要用原形.例： I play football. Do you play football? He plays football. Does he play football? I played football. Did you play football?如何变特殊疑问句特殊疑问句 = 特殊疑问词﹢一般疑问句语序.首先要找对特殊疑问词,疑问词有what, when, how, where, how many,how much,what time, how old……其次会变一般疑问句.例如：I get up at 6 o'clock. 划线的如果是6 o'clock.疑问词就用What time,I get up at 6 o'clock. Do you get up at 6 o'clock? 合起来就是What time do you get up?划线部分去掉,不能自问自答.
