此题选D。她应该知道山顶是非常冷的，因为她刚从那里下来。

v.    理应; 应当，应该; 宜;    

[例句] I think I ought to get back to work.

我想我该回去工作了。

Answer 2

此题应该选择D. ought to know （应该知道）
从下文看 “因为她刚从山顶下来，所以，应该知道山上很冷”。

Answer 3

A - would know. 连接上文下里和动词时间只有这个合理通顺。

Answer 4

我觉得应该选
she can know that it was very cold on the mountain，搭配和语感来的

Answer 5

d 应当知道
