【题目】书面表达
China began relaxing the controversial one-child policy in January 2014, allowing couples to have a second baby if the mother or father was an only child. China will allow two children for every couple, the state-run Xinhua News Agency reported, a move that would effectively dismantle(废除) the remnants(残余) of the country’s one-child policy that had been eased in recent years. China, now a nation of more than 1.3 billion people, instituted a policy of one child per couple to control population growth in the 1970s. The move was hailed as a major liberalization of the three-decades-old restriction. Nationwide, nearly 1 million couples eligible under the new rules had applied to have a second child, state media reported at the time. Health officials had said that the policy would lead to as many as 2 million new births when the policy change was first announced. |
