有读者问： 有这样一道题：
(1)The microscope is a very useful instrument_________scientists can see things that are too small to be seen with the naked eye.
A. in which B. through which
C. with which D. from which
其答案要为C。但高一课本的Galileo and Aristotle 一课中却有这样一句：
(2)He built a telescope through which he could study the skies.
据此，我认为上述句（1）选B合适，不知是否正确？
可以说with或through a microscope。但上述句（1）中which的先行词不是microscope而是instrument，故而应用with which。
