>Women happier without spouse
单身无娃的女性更幸福

We may have suspected it already, but now the science backs it up: unmarried and childless women are the happiest subgroup in the population. And they are more likely to live longer than their married and child-rearing peers, according to a leading expert in happiness.
这件事可能早有人怀疑，但如今有了科学依据：未婚无娃的女性是最幸福的人群。而且，幸福研究权威专家称，这部分女性比那些已婚有孩的女性更长寿。

Paul Dolan, a professor of behavioral science at the London School of Economics, said the latest evidence showed that the traditional markers used to measure success did not correlate with happiness - particularly marriage and raising children.
伦敦经济学院行为科学领域教授保罗•多兰说，最新证据显示，用于衡量成功的传统标志——尤其是婚姻和养育小孩——和幸福无关。

Dolan said men showed more health benefits from tying the knot, as they took fewer risks. But women's health was mostly unaffected by marriage, with middle-aged married women even being at higher risk of physical and mental conditions than their single counterparts.
多兰表示，男性在婚姻中承担的风险更少，获得的健康效益更多，而女性的健康基本不会因婚姻而改善，已婚中年妇女身心受损的风险比单身女性更高。

教育部发赴美留学预警

The Ministry of Education has warned students and scholars who plan to study in the US to be fully aware of and prepared for the risk of possible visa restrictions, as more students are running into problems.
教育部近日发出警告，提醒计划赴美求学的学生和学者充分了解可能出现的签证限制风险，并为此做好准备。

For example, longer waits are required for visa issuance, valid dates have been shortened and the visa rejection rate is on the rise, it said.
越来越多的计划赴美学生正遭遇签证审查周期延长、有效期缩短以及拒签率上升等问题。

According to the China Scholarship Council, 182 government-funded students and scholars failed to get into the US because of visa restrictions from January to March - 13.5% of the total.
根据国家留学基金管理委员会的统计，今年1月至3月，中方计划公派赴美留学人员中有182人因签证问题未能成行，占计划派出人数的13.5%。

Since last year, the US has revoked or reexamined the visas of some Chinese citizens under the pretext of "counterespionage", which has spread from the natural science sector to the social sciences.
2018年以来，美国以"反间谍"为由，吊销或重新审查中方赴美人员的签证，从自然科学领域向社会科学领域扩散。
