1、什么时候have否定式要写成don't have而不写成haven't,举例说明一下
2、是When do you arrive at?还是When do you arrive?什么时候才用介词?Which place did you live in?和which place did you live?
有没有I haven't an apple.

1We don't have any money.
We have much money.
此时have为实意动词表示有.
2arrive后不用加介词,除非后面跟宾语（地点）,When只是一个疑问词.
3Which place did you live in?是正确的.Which place可以看作是in的宾语,如果不想要in,那么换Which place为where.
4从来没有,因为have在这里是实意动词,表示“有”,实意动词的否定式是要在前面加助动词do does did等,然后把助动词换成否定式,东don't doesn't didn't,根据人称和时态,应将这一句改为I don't have any apple.

have to的否定式是不是don't.have.to 改写成下列句子.例句：I haven't got many eggs.They don't have any stati have什么时候否定为haven't什么时候为don't have? should have done 它的否定式是 shouldn't have done 为什么都说I don't have a shirt而不说I haven't a shirt don’t have；haven’t和need的用法 haven't和don't have 有什么不同? haven't和don't have有什么区别 haven't got 和don't have有什么不同 haven't to与don't have to的用法 don't have 和 haven't 有什么区别. don't have和haven't有什么区别?
