Everyone may all have the experience of feeling anxious and stressed when having a rough day or having some troubles. Different people may choose different ways to deal with it, and for most people a break for a 10-minute walk may be quite useful.

Anyway, here is another way around: to get a piece of chewing gum, and chew it. According to a Swinburne University of Technology study, gum-chewing has been found to “relieve anxiety, improve alertness(机敏性) and reduce stress among individuals in a laboratory setting.”

Some may argue that a laboratory is not the same as an office. But check out the conditions of the study: individuals were monitored while performing “a group of ‘multi-tasking’ activities.” Doesn’t it sound like the situation in the office?

Here’s a summary of some of the study’s findings:

Gum chewers showed a reduction in anxiety as compared to non-gum chewers by nearly 17 percent during mild stress and nearly 10 percent in appropriate stress.

Gum chewers showed improvement in alertness over non-gum chewers by nearly 19 percent during mild stress and 8 percent in moderate stress.

Improved Performance: Chewing gum resulted in a big improvement in overall performance on multi-tasking activities.

Although these aren’t major improvements, every little bit works and chewing a piece of gum is a lot quicker and easier than slipping outside for a 10-minute walk. So, how does gum work this magic? In part it does so by lowering the level of cortisol(皮质醇)—a steroid(类固醇) hormone that is released in response to stress in your system.

A few words of advice before you reach for the gum: don’t crack your gum, and be sure to chew it with your mouth closed. In fact, I’d say keep the gum out of meetings, because it really looks impolite to others around you.

199×年×月×日7时30分，××次特快旅客列车，运行到高新线罗家站至高台山站间2km+26m无人看守道口处，与某县新民镇个体大客车相撞，造成65人死亡，4人重伤，5人轻伤的特大路外伤亡事故。
1月31日，担当××次特快列车牵引任务的某机务段内燃机车东方红(3)型0007号，列车编组16辆，总重850t，列车于7时26分，由罗家站通过后，以95km/h的速度运行至该道口鸣笛标前，司机按规定鸣笛示警，在距道口约150m处，司机发现列车运行前方左侧公路上，有一辆大客车由北往南向道口方向行驶，司机立即鸣笛示警，但大客车没有停车迹象，机车司机果断采取紧急制动停车措施，该列车在非常制动状态下与抢越道口的大客车中部相撞，大客车被撞粉碎，机车第二轴两轮被垫脱轨，越过道口457m处停车。汽车乘客当场死亡59人(含司乘2人)、重伤l0人(医院抢救中死亡6人)，轻伤25人。
根据现场勘查和调查认定，肇事道口标志齐全，铺面平整，设备完好。造成这起事故的主要原因是大客车驾驶员薛某违章抢越道口所致。大客车在通过无人看守道口时没有停车，严重违反了《中华人民共和国道路交通管理条例》第44条第2款“通过无人看守道口时，须停车嘹望，确认安全后，方准通过”和国家七部委经交[1986]161号文件第19条关于“车辆、行人通过没有道口信号机的无人看守道口及行人过道时，必须停车或止步瞭望，确认两端均无列车开来时方准通行”的规定。严重违章是造成此次事故的直接原因。此外，大客车定员60人，实际载客94人(含司乘2人)严重超员，加之两侧玻璃有霜，影响瞭望，为此次事故的发生埋下了隐患。
这起事故是大客车驾驶员薛某严重违章抢越道口所致。司机薛某是这起特大路外伤亡事故的直接责任者，本应追究其刑事责任，但因其在事故中死亡，故不再追究。个体业主魏某对此起事故负有责任，由铁路执法机关依法追究其责任。
防止同类事故的措施
1．强化对机动车辆和驾驶员的安全管理和教育。各级政府和主管部门要采取有效的对策，解决机动车辆管理中存在的问题。对所有机动车驾驶人员进行一次全面的安全教育，摆正安全与效益的关系，尤其对个体客车的驾驶员，要做到一车不漏，一人不丢，真正树立安全第一，安全就是效益的思想。
2．发挥三级道口管理委员会的作用。各级道口管理部门要认清形势，明确任务，健全组织，加强动态检查，对易于发生事故的无人看守道口推行有偿监护，确保行人车辆通过道口的安全。
根据以上情形回答下列问题，1～3题为单选题，只有一个正确的答案，4～8题为多选题，有两个或两个以上的正确答案。

这起事故的直接原因是( )。

A．××次特快列车司机未及时停车

B．××次特快列车超速行驶

C．该道口无人看守

D．大客车驾驶员薛某抢越道口

E．大客车严重超载
