能源的未来在于平衡经济增长与环境管理。

The more I learn about memory, the less I trust it.

The secret of living is to own a convertible and a lake...If the sun is shining, you can rid around in your convertible and be happy...If it starts to rain, it won't spoil your day because you can just say, 'Oh, well, the rain will fill up my lake!'"”
