句子: 中国的发展成就，是中国人民几十年含辛茹苦、流血流汗干出来的。千百年来，中华民族素以吃苦耐劳闻名于世。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。可以口译为：Our achievements in development over the past decades owe themselves to the hard work and perseverance of the Chinese people, a quality that has defined the Chinese nation for several thousand years. 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.（ ） A. 对 B. 错
