Question

1.soon we climbed up to the top of the mountain,____the whole city came into view

2.He climbed up to the top floor of the tower and soon his head appeared out of the window,___the whole city came into view.
1.from which 2.from where
2题的选项都为1.from which 2.from where

Answer 1

1. from which = from (the top of the moutain) 从山顶

2. from where = from (out of which) = rrom (out of the window) 从窗子外面

解释：from是一个特殊的介词，它不但可以加名词/代词形成介宾短语，而且还可以加介宾/副词。
如：I come from China.
The tiger jumped from behind the tree.
He has just retured from abroad.
此两题的区别在于对from后面的成分在句意上的不同的把握。
