这是昨天卫报文章的标题：

Parkland teachers faced an impossible choice: 'Do I hold the door open, or close it?'

（我特么是该开门还是关门？）

现在的美国老师在接受日常的训练以应对当有枪手袭击学校

老师们被要求一直锁住教室门，并且躲起来让外面的人看不到里面情况，直到执法力量（law enforcement）进入学校。目的就是让教室看起来是空的。这样枪手就会离开，但是上个月Parkland, Florida 的大屠杀使得这个方法流程陷入一片混乱之中（threw procedure into disarray）因为枪手开第一枪的时候，走廊上就有很多学生。这个时候在教室里的老师就真不知道到底是该开门还是该关门了。

今天的句子：

Teachers were told to keep their doors locked at all times during lessons, and, during an active shooter crisis, to lock the door immediately and not open it. But some teachers who appeared to have followed that procedure to the letter were later attacked by Parkland students and parents for locking students out.

思考题：

Teachers who have followed rules to open the door were criticized by the students.

词汇突破:

follow that procedure 遵守那个流程

to the letter 严格地，不折不扣地

参考译文：但后来，一些似乎严格遵守了这一程序的教师却遭到帕克兰学生和家长的攻击，原因是他们把学生关在门外。

思考题答案：False

明天的句子：

Each of the recent mass shootings in the U.S. have followed a similar pattern—after the killings, there’s a nationwide pang of sadness, a hot flash of anger; but then, after several days of thoughts and prayer and Facebook debates, the conversation dies down. This one, though, seems to have had more staying power.

思考题：

what is the typical pattern after mass shooting in the U.S？
