英语句子判断正误

都不对，第一句回答应该是when did you arrive in beijing最好，回答是I arrived at five

第二句回答是I am staying in my uncle's home.

前两句正确,这里的动词"arrive"的进行时,可以表示将来的意思.
而"stay"这个动词不行,因此后两句错误,应改为:

Where will you stay?
I will stay in my uncle's home.

When will you arrive Beijing?
I will arrive at five .

Where are you going to stay?
I am going to stay in my uncle's house.

将来时常见的是 will + noun
或者 be going to + noun

这两个组句子都对。

第一组用进行时，表示马上要发生的事情。根据句子的描述，显然是在提问的当时，就已经知道对方马上就到北京了。

第二组用进行时，表示现在的状态。
