句法点评：
1. However, in my opinion, students should also be encouraged to raise a question, which is the key to learning.
however表示转折，其后内容往往是作者的观点所在；which引导非限制定语从句，which指代to raise a question。
2. It is said that Einstein’s theory of relativity began with a “beautiful question” he posed—“What if I rode a beam of light across the universe?”
It is said that...为固定句式，意为“据说”；he posed是一个省略关系代词that或which的定语从句，修饰限定先行词beautiful question; pose a question 意为“提出问题”。
