>Arecibo Observatory collapses
美阿雷西博望远镜坍塌
The instrument platform of the 305-meter telescope at Arecibo Observatory in Puerto Rico collapsed overnight, according to the National Science Foundation.
美国国家科学基金会确认，位于波多黎各的阿雷西博望远镜的设备平台坍塌。阿雷西博望远镜口径305米，是地球上最强大的望远镜之一，坍塌是对它的最后一击。
It's a final blow to one of the most powerful telescopes on Earth that has aided astronomical discoveries for 57 years and withstood hurricanes, earthquakes and tropical storms.
工作57年来，阿雷西博望远镜为众多天文发现提供了帮助，并经受住了飓风、地震和热带风暴的考验。
Engineers assessed the damage and determined that all three of the telescope's support towers broke off, sending the 900-ton instrument platform plummeting down to the dish below.
工程师已评估了损坏情况，确定望远镜的三个支撑塔全部断裂，重达900吨的设备平台坠落到下面的碟形反射盘上。
The telescope's support cables also dropped.
此外，望远镜的支撑钢缆也已断裂。
The collapse occurred just weeks after NSF announced that the telescope would be decommissioned and disassembled through a controlled demolition after sustaining irreparable damage earlier this year.
几周前，美国国家科学基金会宣布，阿雷西博望远镜在今年早些时候遭受了无法修补的损毁，将被关闭并以可控方式拆除。
>UK approves Pfizer vaccine
英国批准辉瑞新冠疫苗
Britain has become the first country in the West to approve a COVID-19 vaccine for public use.
英国成为首个批准新冠疫苗供民众使用的西方国家。
The UK Department of Health and Social Care confirmed in a statement to British news agencies that the vaccine developed jointly by American drugmaker Pfizer and Germany's BioNTech would be distributed starting next week.
英国卫生和社会保健部在一份发给英国媒体的声明中证实，美国制药商辉瑞和德国生物新技术公司联合研制的新冠疫苗将从下周起开始发放。
Pfizer was the first of three major Western pharmaceutical companies to apply in both the US and Europe for emergency use authorization.
辉瑞是三家大型西方制药公司中首个在美国和欧洲同时申请紧急使用授权的公司。
In line with planning in the US, British front-line healthcare workers, care home residents, the very elderly and people with underlying conditions that make them particularly vulnerable to COVID-19 complications are expected to get the first doses of the vaccine.
同美国的计划一样，英国一线的医护人员、养老院居民、高龄老人和特别容易发生新冠肺炎并发症的基础病患者将优先接种新冠疫苗。
Pfizer's vaccine, like the Oxford and Moderna formulas, requires two doses about a month apart. 辉瑞疫苗和牛津、莫德纳的疫苗一样，都需要接种两剂，间隔时间一个月。
Matt Hancock, Britain's top public health official, noted the logistical complexities of distributing the Pfizer vaccine, which needs to be stored at around -94 degrees Fahrenheit, but said Britain would get its first 800,000 doses delivered next week.
英国卫生部部长汉考克指出了发放辉瑞疫苗在物流传输上的复杂性，该疫苗需要在零下94华氏度(零下70摄氏度)的温度条件下储存，但他表示下周第一批疫苗共80万剂将运送到英国。
The UK has a total of 40 million doses of the Pfizer vaccine on order, enough to fully treat 20 million people.
英国共下单了4000万剂辉瑞疫苗，足以让2000万人接种。
