Is anyone else pre-med here? Okay, so a pretty good showing. So maybe you can relate to some of the reasons I wanted to be pretty pre-med -- part of it was the interest in the science and the biology. Also, I wanted to help people -- it seemed like a really clear way that I could have a career that was challenging and involved in science, but also helping others.

你们中有医学预科的吗？,不错，有不少人,也许你们出于和我当年,想读医学预科一样的原因,一方面是受灾科学和生物学方面兴趣的驱使,另一方面,我想帮助别人,所以我似乎应该选择。
