市南区中医医院贵么青岛妇幼保健医院怎么样好吗China is to do away with its controversial one-child policy, according to state-run news agency Xinhua.据中国官方通讯社新华社报道,中国将废除备受争议的独生子女政策。The ruling Communist Party reportedly announced the decision to allow two children per couple at the end of a summit to finalise its next five-year plan.据报道,在经过确定下一个五年计划的高层会议后,执政的共产党宣布每对夫妇可以生育两个孩子。Introduced in 1979, the policy limited most couples to only a single offspring.计划生育于1979实施,该政策限制大多数夫妻只能生育一个子女。Authorities argued the subsequent economic boom was a result of the law. However, a rapidly ageing population, shrinking workforce and gender imbalances now suggest otherwise.当局认为该政策促进了随后的经济繁荣。然而人口的老龄化、劳动力的下降以及男女的不平衡却与此截然不同。Limited exceptions to the policy were introduced two years ago, but China continued to suffer economically, with experts predicting it could be the first country ever to grow old before it becomes rich.政策的限制例外于两年前推出,但中国继续遭受经济上的损失,有专家预测中国可能成为第一个未富先老的国家。译文属。 /201510/406902莱阳儿童医院男科怎么样 栏目简介:《趣味青春英语视频》是外语网络电台的精品节目,通过大讲堂的网络课堂形式,能够帮助英语学习者积累一些英语背景知识,并通过互动的教学形式,帮助有效记忆英语知识。本栏目是学习趣味青春英语的好材料。201604/431263栏目简介:;Shanghai Live; focuses on big events in the city and major issues around the world, and presents them in a practical and audience-friendly manner to meet the ever-evolving needs of Shanghais English-speaking viewers,both local and expatriate.《直播上海英语电台》集中报道城市大事件以及全球热点话题,并以观众喜闻乐见的方式呈现给大家,从而满足上海本地以及上海海外人士的英语需求。201602/428162青岛人流手术哪家比较好
