arrive at可用在疑问句句末吗?就是一个句子中Which city do you want to arrive at?还是Which city do you want to arrive?

Which city do you want to arrive at?

很抱歉地告诉你，arrive一般不会用在这种疑问句里的。就算用，也不需要加上介词at。
建议改为“which city do you want to go?”

前面的

应是：Which city do you want to arrive in?
arrive+at+小地点
+in+大地点

arrive是不及物动词,接宾语需要加介词at,in.在疑问句中,放在句尾时,加不加介词取决于两个因素.一是arrive 后加不加宾语.二是疑问词是代词还是副词,代词就加,副词不必加.
如：which city do you want to arrive at?which 是疑问代词,在句子里做arrive at 的宾语,介词不能省略.
另 when are you going to arrive?arrive后没有宾语,不需要介词
where do you want to arrive?where是副词省略介词

按语法的话Which city do you want to arrive at/in?
但是正常人都不会这么说话的啊
which city do you want to go？就行了...

Which city do you wang to arrive at?
arrive at加名词 代词 动名词，which是疑问代词..
