【正确答案】Now, as we enter this new century, even greater advances lie before us. Scientists are turning to new genetic databases, high-powered computers, and other tools. They are unraveling mysteries about how our bodies develop and how our brains store the memories of a lifetime. If I were a young person looking to make a contribution in this new century, I would look first to biology. It is an arena filled with important problems, fascinating questions, and a spirit of adventure. Also, like all of science, it is an arena that includes the entire world rather than any one nation. China, with its proud scientific history, is already producing some of the best researchers, but it has the potential to do even more. The world looks to the young people of China for both their brains and their hearts to help advance science and make the planet a healthier and better place for all of us.
