市面上有甚麼適合中學生閱讀的英文雜誌？

Time & Reader Digest are pretty good for high school/ secondary school students. Or Popular science or Money.
Depends on what you want to read though...
However, if you like to read any kind of beaut magazines, like Cosmopolitan, it also helps you to learn English.

or you could just google magazines for more informations.

Hope it would help~! ^^

It depends on what are you interested in. If you are interested in sciences, whynot trying "New Scientist"

If you are looking for a job, "Recuit" is a good one too
