如果有一句：I have a car.改为否定句是I don't have a car 还是直接把have改变?还有把h I have a car改为一般疑问句,否定句 I have a car I don`t have a car.与I don have any cars有何不同? 把I have a good kite改为否定句 I don't have much money to buy a car同义句 my parents have a car!改为否定句 i don't have enough money .so i think i will buy a u____ car I have a bag.改为否定:I have not a bag.I don't have a bag.哪个对? I don't have enough money,so I want to buy a u___ car I beg you to marry me even though I don't have a car did not I have a basball.改为否定句
