为防校园枪击案，美国得州多个学区要求学生背透明书包
Dallas joins other Texas school districts in requiring clear or mesh backpacks after Uvalde massacre

The Dallas school district announced Monday that it will require students to carry clear or mesh backpacks to class, joining other Texas districts in implementing new security measures following the Uvalde school massacre.在乌瓦尔德校园枪击案发生后，达拉斯学区7月18日宣布，和得克萨斯州其他学区一起实施新的安全措施，要求学生携带透明或网状背包上学。

"We acknowledge that clear or mesh backpacks alone will not eliminate safety concerns," the district said in its announcement. "This is merely one of several steps in the district's comprehensive plan to better ensure student and staff safety."达拉斯学区在公告中表示：“我们承认，仅仅凭透明或网状背包并不能消除安全隐患，这只是学区全面安全计划中的措施之一，目的是更好地确保学生和教职员工的安全。”

The decision was made based on feedback from students and parents, as well as recommendations from a safety task force at the district, the district said.该学区表示，这一决定是根据学生和家长的反馈以及学区安全工作组的建议做出的。

The Dallas school district isn't the only one in Texas stepping up security measures.达拉斯学区并不是得州唯一一个加强安全措施的学区。

A school district in Greenville, about 50 miles northeast of Dallas, announced in early June a shift to clear backpacks and that it would implement additional security measures for the upcoming year, which include keeping classroom doors locked at all times and limiting access points into its schools.位于达拉斯东北约50英里的格林维尔学区6月初宣布，将规定学生携带透明背包，并将在来年实施更多安全措施，包括始终锁住教室门，限制进入学校入口等。

After the 2018 shooting that claimed the lives of 14 students and three adults at Marjory Stoneman Douglas High School in Parkland, Florida, students were required to carry clear backpacks when they returned to school after spring break.2018年，佛罗里达州帕克兰的马乔里·斯通曼·道格拉斯高中发生枪击案，造成14名学生和3名成年人死亡。此后，学生们在春假后返回学校时被要求携带透明的背包。

In Texas, several of the districts have specified that students will be able to carry small non-transparent pouches in their backpacks to hold personal items like money and hygiene products.得州一些学区已经规定，学生可以在背包中携带小的不透明袋子，以存放现金和卫生用品等个人物品。

Some students have to pass through metal detectors when they get to school every morning, and many around the nation undergo active-shooter training.一些学生每天早上上学时必须通过金属探测器，全美各地许多学生都接受了主动射击训练。
