Question

    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．

【解析】

本文为说明文。文章介绍了人们产生手机振动的幻觉的原因，并给出了解决办法。

1.细节理解题。根据第三段中的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 don’t miss anything．（然而，有时你的大脑会认为错过一个电话的后果比“误报”更严重。所以，你对振动变得更加敏感，因此你不会错过任何事情）可知，当我们的大脑对错误的信号做出敏感的反应时，电话振动幻觉就会发生。故C选项正确。

2.推理判断题。根据第三段中的This is just like the fire alarm in your home（这就像你家的火灾报警器一样），this指的电话振动幻觉，由此可推知，这个例子是为帮助我们更好地了解手机振动幻觉的原因。故B选项正确。

3.细节理解题。根据第三段中的The answer is that your brain bears a heavy burden every day．"You get a large amount of sensory(感觉的) information that’s coming from your eyes，ears and skin，and you can’t deal with all that information all the time，"（答案是你的大脑每天都承受着沉重的负担。“你的眼睛、耳朵和皮肤会产生大量的感觉信息，你不可能一直处理所有这些信息。”）可知，每天脑袋接受信息和处理信息的负荷很重，这是产生手机振动幻觉的主要原因。此题易误选C，C表达的是生活压力大。故D选项正确。

4.细节理解题。根据最后一段中的So，perhaps you should just check your phone whenever you think it's vibrating．（所以，当你认为手机在振动的时候也许你应该检查你的手机），可知，当我们感觉手机在振动时，我们应该检查我们的手机。故B选项正确。
