我看到他们在山上滑雪想知道他们的计划是在那里度过整个假期还是只是短暂停留?我会问一句Are they staying in the mountains for their vacation or are they just stopping there for a few days?

他们计划在那座山脉中度过整个假期。看看，这正是语言学习中的一种情况： Im on my way to the airport and will be flying home tonight. Where are you going Im going home. See how that works Theyre saying the same thing but it sounds different based on the context. So practice speaking in this way

Are they staying in the mountains for their vacation or are they just stopping there for a few days他们将待在山上度假，还是只是住几天.

Their plan is to spend their entire vacation in the mountains.不说谎。

他们打算在山上度假，所以他们在那里停留整个假期。不说话就听个笑话吧！

他们计划在山上度过整个假期，所以答案是staying.ゃすいでしょう。

他们是去度假的地方吗（Are they staying in the mountains for their vacation）.没有任何上下文信息，无法确定他们的计划。

他们计划在山上度过整个假期。正是如此，他们将在那里度过整个假期。

Staying指的是在某个地方住下来，所以你会得到的答案是他们将度假期间住在山顶。没有任何疑问的表达方式能比这样更了。
