Do you ever pull your phone out of your pocket, thinking it is vibrating （振动） , only to find that it isn't?
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 brain's 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 isn't.
Ideally, you match the four states correctly.However, sometimes your brain decides that the consequences of missing a call are more serious than a "false alarm".Therefore, you become more sensitive to vibrations so that you don't 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 that's 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 can't 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 information that's coming from your eyes, ears and skin, and you can't 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 it's vibrating.It's 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 people's ability to collect information
C.happens when our brains react sensitively to false signals
D.helps our brains to make quick and accurate decisions
2.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.
3.Why is the fire alarm used as an example in this passage?
A.To help us understand the cause of phantom phone vibration better.
B.To show us the fire alarm is as sensitive as the phone vibration.
C.To tell us the phone vibration usually happens when a fire breaks out.
D.To convince us it's important to check our phones like checking a fire alarm.
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 they're 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.

Ever notice your phone dies faster in cold weather? But why? As LiveScience reports, it all comes down to chemical reactions within the battery.
If you were to open any smartphone, you'd probably find a Li-ion(锂离子)battery running the show. Inside the battery, there are two poles, a positive pole(正极)and a negative pole(负极), and how much charge your phone has all depends on which side the ions stay. A fully charged battery will be jam-packed with ions on the positive end, while a dead battery will have all the ions stored in the negative end.
Your phone is powered as the individual ions travel in solution(溶液)from one pole to the other, but a cold temperature doesn't cause the Solution flow in the battery itself. If it flowed, the ions would have to go somewhere, but they actually stay put when it gets cold. The cold temperature causes chemical reactions that slow down the current(电流). The only other time this smaller current is sent through the battery is when all the ions have been spent, so your phone mistakenly reads the slowdown as being out of power.
Now, how can you get yourself out of this situation? Dr. Stephen J. Harris, a chemist at the Lawrence Berkeley Lab, says whatever you do, don't charge it. Your fully charged battery isn't lacking ions, and the cold temperature isn't allowing more ions to be pulled into the anode. They pass through the solution as solid lithium, which can really do some serious damage to the battery cell itself.
The only way to get the battery back to life is to let it return to its normal operating temperature. We recommend leaving it in your pocket or spending a few minutes inside away from the bitter cold.
1.What do we know about the battery?·
A.We can just charge one side of it.
B.A dead battery stores no ions inside.
C.It's full with all ions on the negative end.
D.Smartphones are powered by Li-ion batteries.
2.What makes the phone dead in the cold weather?
A.The lack of ions. B.The loss of solution.
C.The slowdown of the current. D.The disorder of the ions.
3.What might Dr. Stephen agree to do when your phone dies in the cold?
A.Leave it in the cold. B.Warm it in the pocket.
C.Get it charged immediately. D.Restart it immediately.
4.What may be the best title of the text?
A.Reactions Inside the Battery B.Ways to Keep Phones Alive
C.Cold Weather Kills Your Phone D.How Phones Work Under Cold Weather
