没想到，如今时值考试季，有的年轻人竟然也加入了“听风者”的行列。不过，他们听的可不是敌人的电台，而是考试时旁边同学写在纸上的选择题答案“ABCD”

Didn't think,Now as the exam season,Some young people have also joined"Listen to the wind"ranks.but,They hear is not the enemy's radio,But when the exam flank classmate write on the paper choose the answer"ABCD"

听声辨答案“ABCD” Listen to sound distinguishes the answer"ABCD"

网传考试秘笈 Pass the exam and secret

　　又到各校期末考试，寒假能否过得HAPPY，就看试卷上的分数了。近日网上热传一份考试秘笈，号称仅凭邻桌的笔画声，就可判断选择题的答案。

To the schools and the final exam,Can have a HAPPY winter vacation,See the scores on the test paper for.Recently online heat transfer a test code,With only known at the sound of strokes,Can judge choice question answer.

　　这份秘笈宣称：静下心仔细听同学写在试卷上的选择题笔画声，就可“抄”下选择题的答案。为什么能这样呢？秘笈说得还挺有道理，因为选择题有ABCD四个选项，四个字母在书写时略有不同：A有三画，C只一画，BD虽都是两画，但B在书写时由于第二画有弯，比D花的时间长，仔细听不就能辨别出来了。

The secret that:Got down to listen carefully classmate to write on the paper in the multiple-choice stroke sound,can"copy"Choose the answer to the question.Why can do this?Secret said it is quite reasonable,Because choice have ABCD four options,Four letters when writing a little different:A three paintings,C a picture,Although BD is two paintings,But B when writing due to the second picture is curved,Than D it takes a long time,Listen carefully don't can distinguish out.

扬子晚报实验 Yangzi evening news experiment

真没想到，正常书写速度下 单选题居然能“听”对80% I didn't know that,Normal writing speed under single subject could"Listen to"To 80%

　　通过听声辨答案，这真能实现吗？昨日，扬子晚报记者请两位大学生进行了实验，令人惊讶的是，看似天方夜谭的“听声辨答案”还真有一定的准确率，在正常书写速度下，准确率居然能达到80%。

Through the sound distinguishes the answer,It can realize?yesterday,Yangzi evening news reporter please two college students experiment,Surprisingly,Seems the Arabian nights"Listen to sound distinguishes the answer"There is a certain accuracy,In normal writing speed down,Accuracy could reach 80%.

实验准备 The preparation

　　测试目的：单纯通过聆听签字笔在纸上书写时的声音，看看能否将ABCD四个选项准确的分辨并复写下来。

Test purpose:Only by listening to sign pen on the paper when writing voice,To see whether the ABCD four options accurate resolution and copy down.

　　测试工具：签字笔两支，普通信纸和高级光滑信纸各一张，记号笔若干。

Test tools:Sign pen two,Ordinary paper and senior smooth letter each one,Marker several.

　　测试人：扬子晚报记者(坐前排，先写)

Test people:Yangzi evening news reporter(Sit in front of the,write)

小阳：广电专业大三学生 Small Yang:Radio and television professional junior student

测试方法 Test method

　　测试分为两轮，前一轮由扬子晚报记者以正常的速度在普通纸张上书写英文字母，另两名同学“听写”。第二轮由记者以较快的速度在光滑的纸张上书写，另两名同学听写。在每轮测试，每书写五个字母稍作停顿。被测试同学凭借声音将记者所写的“拷贝”下来。

The test is divided into two rounds,Former round by yangzi evening news reporter to normal speed in ordinary paper writing English letters,Two other students"dictation".The second round by a journalist with the faster speed in smooth paper writing,Two other students dictation.In each round of test,Each writing five letters a pause.By testing the students with sound will be written in the press"copy"down.

　　尽量模拟考场环境，室内尽量杜绝杂音，为保证测试的准确性，参与测试的两个同学以一前一后的形式坐定。

Try to simulate the examination room environment,Indoor try to eliminate noise,In order to ensure the accuracy of the test,Participate in the test two classmates in the form of tandem come sit quietly.

写的越慢，“听”对的越多 Write the slower,"Listen to"The more you to

　　在第一轮测试中，因为书写的速度较慢，所以被测试同学的听写复制能力还是不错的。小菲同学听写对了17个，错误个数是3个。小阳同学听写正确数为16个，错误个数是4个。两人的测试过程都比较顺利，且错误率都没有超过20%。综合两人的测试结果不难发现，错误的地方只存在于“A”和“B”，或“A”和“C”之间的判断模糊。

In the first round of tests,Because of the writing speed is slow,So was the dictation ability test students copy or good.Phillips students dictation to 17,Mistake number is three.The little male classmate dictation right number is 16,Mistake number is four.Two people's test process is smooth,And error rate no more than 20%.Comprehensive two test results is not difficult to find,The wrong place exists only in"A"and"B",or"A"and"C"Between the fuzzy judgment.

写快了，AD、BD难分辨 Write faster,AD/BD difficult to distinguish

　　在第二轮测试中，测试同学的书写速度明显加快，所以很多字母都出现了连笔的情况，这也在无形中增加了听写者的难度。因此，两位同学的错误率较之前都有不同程度的上升。

In the second round of test,Testing students writing speed significantly speed up,So a lot of letters have appeared the cursive,This also is in virtually increased the difficulty of the listener.so,Two students are error rate before has the varying degree rise.

　　其中，错误最多的，除了原先的“A”和“B”之外，又多了“A”和“D ”。究其原因，因为字母A在快速书写时，由于连笔作用简化成了两笔，与字母D相同，因此很容易混淆。此外，把“B”听成“D”的情况也相继发生。这是因为字母B在连笔的时候，最后一个弧度会用力很轻，听写者在听的时候很难抓住最后的尾音，自然而然会以为是D。所以把B听成D也就不足为奇了。

the,Mistake most,In addition to the original"A"and"B"outside,And much"A"and"D ".Investigate its reason,Because A letter in A fast when writing,Due to the cursive action simplified become two pen,And letter D the same,It is easy to confuse.In addition,the"B"Listen to into"D"The situation is ensued.This is because the letter "B" in the cursive,The last one radian will force is very light,Listener when listening difficult to catch the last end,Naturally thought is D.So the B listen to into D no wonder.

纸越粗糙，“听”对的越多 Paper the rough,"Listen to"The more you to

　　因为在测试的环节中，被测试者主要是根据测试者的书写声音而判断字母选项的，所以声音的清晰度就是能否听写成功的最为关键的因素。而书写发出的声音就是笔尖与纸张接触摩擦所发出的声音，在这两组测试中，测试者分别使用了两种不同材质的信纸作为测试工具。一种是较为光滑的高级信纸，另一种是质感一般、纸质粗糙的普通信纸。

Because in the test in the link,Subject is mainly according to the testers writing voice and judgment letter options,So the clarity of the sound is can dictate the success of the most crucial factors.And the sound of writing is the pen and paper contact friction from the voice,In the two groups of tests,Testers are using two different material of paper as a test tool.One kind is relatively smooth senior writing paper,Another kind is the general sense/Paper rough ordinary paper.

　　测试结果表示，在光滑的高级纸上听写字母，其正确率明显低于粗糙的普通信纸。原因显而易见，由于普通信纸表面粗糙，所以测试者在书写时，笔尖与纸张表面的摩擦力就增大，也就是俗称“抓地力”更强了。摩擦力一大，发出的声音自然就大了。所以纵使是一些不容易被听到的尾音、顿笔也能让被测试者听得很清楚。而高级信纸由于其做工精良，表面抛光，所以书写时摩擦力很小。那些本来就不易被发现的尾音自然“藏匿”得更深了。

Test results said,In the smooth senior paper dictation letters,Its accuracy was significantly lower than the rough ordinary paper.Obvious reasons,Due to the common paper surface roughness,So testers when writing,Pen and paper surface friction increases,Is also commonly known as"grip"Stronger the.Friction a large,The sound of nature is great.So even if is not easy to hear some end/Meal pen can also let the testers could be heard clearly.And senior paper due to its excellent work,Surface polishing,So when writing friction force is small.Those who could not be discovered natural end"hiding"deeper.

英语专业同学准确率更高 English major students higher accuracy

　　实验中，扬子晚报记者发现了一个有趣的现象：测试的数据显示，同样的纸质，在快速书写的情况下小菲的听写正确率要比小阳高出许多。即便在正常情况下，小菲的准确率也比小阳高这又是为什么呢？其实，这靠的就是后天“培养”的能力了。

In the experiment,Yangzi evening news reporter found an interesting phenomenon:The test data shows,The same paper,Writing in a fast under the condition of the dictation phillips accuracy than small Yang much higher.Even in normal circumstances,Phillips accuracy is better than small Yang high this is why?In fact,It depends on the day after tomorrow"training"ability.

　　原来，小菲是英语专业的学生，模拟听力和语感练习这在平时上课的时候都是家常便饭。在长期的听力练习中，小菲的抓听能力变得很强，书写速度也可见一斑。

The original,Phillips was an English major students,Simulation listening and practice the language sense in time when the class is the norm.In the long-term practice of listening,Phillips grasp of the ability to become strong,Writing speed can be measured by the.

　　“其实我感觉这跟我的专业还是有一定关系的。”在学校，小菲每次上实践课都要戴着耳麦听写句子，那可是影视原声。那个难度肯定比这个测试里的单纯听书写声音大多了。“老外说话不光快，还喜欢连读，所以我们英语专业的学生都比较擅长抓尾音和单词的韵脚。我们听的次数多了，时间久了，可能自然而然地就把这个习惯带到生活里了。”小菲说。

"In fact I feel it with my professional or have a certain relationship."In the school,Phillips on each practice classes to wear a headset dictation sentence,That's the original film and television.The difficulty with this test must be higher than the simple to write most of the voice."Foreigners speak not only fast,Also like even read,So we English major students are better at catch end and words of the rhyme.We hear more often,Time is long,May naturally put the habit to the life."Phillips said.

专家解析 Expert analysis

不是特异功能 其实普通人都能做到 Not specific function in fact that ordinary people can do it

　　在东南大学附属中大医院耳鼻喉—头颈外科主任黄志纯看来，“听声辨字”算不上特异功能，“普通人都能做到。”比如电话键盘音，“从1到9，每个音的声音不一样，返回到大脑的感觉一样，仔细听上一段时间后，就可以准确辨别出来。”

In the southeast university affiliated zhongda hospital ent - head and neck surgery HuangZhiChun director looks,"Listen to sound distinguishes the word"Not a specific function,"Ordinary people can do."Such as phone keyboard sound,"From 1 to 9,Each tone of voice is not the same,Return to the brain as it is,Listen carefully in a period of time,Can accurately recognize."

　　听写字母也是同样的道理，写A、B、C、D选项，是学生比较熟悉的，写不同字母时，声音远近不一样，长短也不一样，“比如A写三画，笔尖在纸上画过的声音长，C只有一画，较短，B和D都是两下，只要仔细听通常能听出来。”黄主任认为，如果稍加训练，准确率会更高。“准确率和距离有关系，如果采取一考多卷，周围同学跟你考的不是同一张卷子，可以有效遏制这种作弊方式。”

Dictating letters is also in the same way,Write A/B/C/D option,Is the student is familiar,Write the different letters,Sound distance is not the same,Length is not the same,"Such as A write three paintings,Pen on the paper painted voice long,C only one picture,short,B and D are two times,As long as listen carefully usually can hear out."Yellow director think,If a training,Accuracy will be higher."Accuracy and distance have relations,If take a test more volumes,Around the students with your exam is not the same piece of examination paper,Can effectively curb the cheating way."

“实战”很难：要求太高，成功率太低 "Actual combat"It is difficult to:Asked too much,Success rate is too low

　　参与实验的小阳告诉记者，如果真在考场中如此作弊，恐怕成功几率不会太高。“因为必须满足诸多条件。”小阳说，首先对方必须是高材生，否则就是全听对了，他写的是错误答案，你跟着也都错了；其次，写答案时，这名同学还必须慢慢悠悠地写，快了就听不清；同时，还必须祈祷考卷选用了粗糙的纸张来打印，否则纸张越好，正确率越低。

Participate in the small Yang told reporters,If really in the examination room so cheating,I'm afraid success probability will not be too high."Because must meet many conditions."Small Yang said,First of all the other party must be a top student,Otherwise it is to listen to the whole,He wrote the answer is wrong,You follow are wrong;secondly,Write the answer,The students must also write the slowly,Fast and couldn't hear;At the same time,Must also pray papers choose the rough paper to print,Otherwise the paper, the better,Accuracy is lower.

　　扬子晚报记者随机采访了10名大学生，这样的考试秘笈真能助考吗？10人中只有2人表示，听上去还不错，有点想试试；其余8人均表示太费事，成功率太低。一名文科专业的同学说，“我们考试选择题的比例相对较低，其余都是文字解答。费半天劲，不一定能填对，何必呢？”(大学生记者 吕新阳 记者 蔡蕴琦 文/摄)
