例句

1. 中国人民深知，世界上没有免费的午餐，中国是一个有着13亿多人口的大国，想发展就要靠自己苦干实干，不能寄托于别人的恩赐，世界上也没有谁有这样的能力。--《习近平主席在世界经济论坛2017年年会开幕式上的主旨演讲》

1. We Chinese know only too well that there is no such thing as a free lunch in the world. For a big country with over 1.3 billion people, development can be achieved only with the dedication and tireless efforts of its own people. We cannot expect others to deliver development to China, and no one is in a position to do so.--Quoted from Keynote Speech At the Opening Session of the World Economic Forum Annual Meeting 2017
