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

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是实义动词的时候用don't have I don't have a cat.
是助动词的时候用haven't I haven't bought a car.
When do you arrive? 后面跟地点时用介词。
Which place did you live in？ Which place相当于宾语，live是不及物动词，所以要用in.

have是实义动词的时候写成don't have
做助动词的时候写成haven't
When do you arrive?是对的
Which place did you live in?是对的
两个句子的不同在于when和which这两个词的不同。

1.HAVE作行为动词时否定要写成don't have,have作为行为动词主要译为"有"比如I have an apple否定句就是I don't have an apple
当 have 作助动词时否定是haven't
比如:Have you ever been to Harbin?否定就是No I haven`t
2.arrive后接地点时加AT
