I have just been watching you with the telescope I have just been watching you by the telescope

问题描述:

I have just been watching you with the telescope I have just been watching you by the telescope
I have just been watching you through the telescope
哪一个对

through
通过、透过
这里考试要点是介词,看什么东西,的确with/by都可以表示“用...(工具)”,但这里望远镜是透过看的,through是更恰当的,因此用through
