    The government in China ended his one-child policy and let families have two children instead in 2015.

    A Chinese Communist Party statement gave a number of reasons for the change in policy. The statement said the change is meant to balance population development, stop a falling birth rate(出生率)and strengthen the country's labor force(劳动力). China, with the largest population in the world, started the one-child policy in 1980. But the government allowed only a small number of couples to have two children. For example, some families in the countryside could have two children, if the first-born is a girl.

    In 2013, the Chinese government gave other couples a chance to have two children if one of them was an only child.

Jiang Quanbao, a teacher and population expert, explained how Chinese families react(反应) to the newest policy. "Too many young people in the cities are no longer interested in having a second child," he said. "People in the countryside are more interested. But some of them are already allowed to have two children." At the end of 2014, China had a population of 1.37 billion people. A total of 800 million of them have jobs. But the labor market need of labor by the year 2050. With the two-child policy, an increase in births can solve this problem.

    Boys and girls, what do you think of the two-child policy? Do you want to have a new-born brother or sister?

平分生命

       男孩与他的妹妹相依为命。父母早逝，她是他唯一的亲人，所以男孩爱妹妹胜过爱自己。

       然而灾难再一次降临在这两个不幸的孩子身上。妹妹染上重病，需要输血。医院的血液太昂贵，男孩没有钱支付任何费用。尽管医院已免去了手术费，但不输血妹妹就会死去。

       作为妹妹唯一的亲人，男孩的血型和妹妹相符。医生问男孩是否勇敢，是否有勇气承受抽血时的疼痛。男孩开始犹豫，十岁的大脑经过一番思考，终于点了点头。

       抽血时，男孩安静地不发出一丝声响，只是向着邻床的妹妹微笑。抽血完毕后，男孩声音颤抖地问：“医生，我还能活多长时间？”

       医生正想笑男孩的无知，但转念间又被男孩的勇敢震撼了：在男孩十岁的大脑中，他认为输血会失去生命，但他仍然肯输血给妹妹。在那一瞬间，男孩所作出的决定是付出一生的勇敢，并下定了死亡的决心。

       医生的手心渗出了汗，他紧握了男孩的手说：“放心吧，你不会死的。输血不会丢掉生命。”

       男孩的眼中放出光彩：“真的？那我还能活多少年？”医生微笑着，充满爱心地说：“你能活到一百岁，小伙子，你很健康！”男孩高兴得又蹦又跳。他确认自己真的没事时，就又挽起胳膊——刚才被抽血的胳膊，昂起头，郑重其事地对医生说：“那就把我的血抽一半给妹妹吧，我们两个每人活五十年！”

       所有的人都震惊了，这不是孩子无心的承诺，这是人类最无私纯真的诺言。
