因新冠确诊病例上升，纽约市将从本周四起再次关闭学校转为网课

纽约市长Bill De Blasio在告诉家长们：“为了阻止再次上升的确诊病例，纽约市决定在本周四开始再次关闭学校，转而远程学习。” 市长还说：“纽约市本周三测试确诊新冠的阳性率达到了3%，这个阳性率是纽约市关闭教室的标准。”

The shuttering of the nation’s largest school system had been anticipated for days after de Blasio told parents on Friday to have a plan in place in case the city decided to close schools for in-person learning, NBC News New York reported. Remote learning will begin Thursday, the mayor said in breaking the news over Twitter. The mayor said the city would close classrooms if the citywide positivity rate, or the percent of Covid-19 tests that are positive, hits an average of 3%. That was reached on Wednesday.  source
