The future of coal lies in clean and efficient utilization.
有时最简单的旋律承载着最深刻的情感。
A theory should not attempt to explain all the facts, because some of the facts are wrong.
未来属于那些能够跨越界限合作的人。
我遇到的那些让我钦佩的人,无一例外都比我读的书多。
生命的历史是生存的历史。
Hope is a good thing, maybe the best of things, and no good thing ever dies.
