You’re in your office when you learn there’s someone with a gun wandering outside. You can hear gunshots and screams. What do you do?
That’s the challenge for users of a new virtual (虚拟)reality program called SurviVR, designed to train employees how to deal with an active shooter situation in the workplace. The program works with HTC Vive, the virtual reality headset released earlier this year.
An active shooter situation is when an armed person or people actively shoot in a small, populated area with the intention to kill. There were 20 such situations in the United States last year and 20 the year before, according to FBI statistics, resulting in a total of 231 deaths. This year saw the deadliest active shooter situation in US history, with 49 people killed in a nightclub in Orlando.
In the training situation, users have four choices. They can lock themselves in the office. They can hide, perhaps in the office closet. They can run for an exit. Or they can use something in the office—a computer or a cup a pair of scissors-as a weapon to fight the shooter. This is an improvement on standard active shooter training. Gallo says, which typically teachers people to lock themselves in place and hide. The "lock down" method is often ineffective, he says, and has resulted in many deaths in recent years.
In the training’s basic level, no one gets killed. But as the trainings become more advanced, players who make a wrong choice be shot. There’s no blood; the screen simply turns black slowly.
If this sounds terrifying, that’s the point, says Gallo. There are plenty of training programs to teach employees how to deal with workplace violence, sometimes involving role play with toy guns. But these trainings are basically games. Gallo says, with employees relaxed and even enjoying themselves. To teach people what they really need to know for an active shooter situation, they need to be scared.
"SurviVR will take the fear and turn it into confidence." Gallo says.
1.What’s the author’s purpose of describing a dangerous scene in Para. 1?
A.To attract the readers’ attention on the new virtual reality program.
B.To show the challenge that the readers are required to face.
C.To warn the readers of the possible dangers in the working place.
D.To inform the readers of the correct response in such a situation
2.What is the suggested response in the standard active shooter training?
A.Fighting the shooter
B.Running for the exit
C.Using a computer as a weapon
D.Locking down
3.What does Gallo think of the training programs involving role play with toy guns?
A.Searing B.Violent
C.Ineffective D.Helpful
4.What would be the best title?
A.A New Virtual Reality Program on Active Shooter Training
B.What Should You Do When Meeting Gunshots in the Workplace?
C.How to Deal with an Active Shooter Situation?
D.Employees Need to Be Scared of the Workplace Violence.

Do you ever pull your phone out of your pocket,thinking it is vibrating(振动),only to find that it isnˈt?This phenomenon,which scientists call"phantom(幻觉的)phone vibration",is very common.Around 80% of people surveyed say they have imagined their phones vibrating when they were actually still.
So,what leads to this universal behavior?According to the BBC,the explanation lies in your brainˈs ability to discover signals from the outside world.When your phone is in your pocket,there are two possible states:it is either vibrating or not.Meanwhile,you also have two possible states of mind:the judgment that the phone is vibrating,or that it isnˈt.Ideally,you match the four states correctly.
However,sometimes your brain decides that the results of missing a call are more serious than a"false alarm".Therefore,you become more sensitive(敏感的) to vibrations so that you donˈt miss anything. This is just like the fire alarm in your home---it can be annoying when it goes off in response to just a tiny bit of smoke.But thatˈs a small price to pay compared to a fire really breaking out because the alarm fails to alert you.Now,you might still ask:why canˈt our brains just make every judgment correctly without being too sensitive to false signals?The answer is that your brain bears a heavy burden every day."You get a large amount of sensory(感觉的) information thatˈs coming from your eyes,ears and skin,and you canˈt deal with all that information all the time,"Michael Rothberg,a researcher at Baystate Medical Center in Springfield,US,told Live Science.
For example,the rustling(沙沙声)of clothing or the growling(咕咕声)of your stomach may both lead your brain to believe that they come from the vibration of your phone-it is like trying to hear your name being called in a noisy room.
So,perhaps you should just check your phone whenever you think itˈs vibrating.Itˈs not too much trouble to do that,is it?
1.According to this passage,phantom phone vibration ______ .
A.is common among people with mental problems
B.can measure peopleˈs ability to collect information
C.happens when our brains react sensitively to false signals
D.helps our brains to make very quick and accurate decisions
2.Why is the fire alarm used as an example in this passage?
A.To show us the fire alarm is as sensitive as the phone vibration.
B.To help us understand the cause of phantom phone vibration better.
C.To tell us the phone vibration usually happens when a fire breaks out.
D.To convince us itˈs important to check our phones like checking a fire alarm.
3.According to Michael Rothberg,which is mainly responsible for phantom phone vibration?
A.A noisy background. B.A lack of much attention.
C.A heavy burden every day. D.An overflow of sensory information.
4.What does the author suggest we do about phantom phone vibration?
A.We should always fully believe our own sense of listening.
B.We should just check our phones whenever we think theyˈre vibrating.
C.We should ignore the vibration bothering when our phones are actually still.
D.We should think of the vibration carefully before we make correct judgments.
