知识的责任。
美国，或者说波士顿，最大的魅力或许就在于责任与学术。
在查尔斯河畔，在校园的钟声里，在图书馆的灯光下，我愿意花上30年去研究一个问题，追寻一个答案。
The Responsibility of Knowledge.
Perhaps the greatest charm of the United States—or, more specifically, Boston—lies in a sense of responsibility and academic pursuit.
On the banks of the Charles River, amid the chimes of the campus bells, and under the lights of the library, I would be willing to spend 30 years researching a single question and searching for an answer.
