The problem of robocalls has gotten so bad that many people now refuse to pick up calls from numbers they don't know.By next year，half of the calls we receive will be scams（欺詐）.We are finally waking up to the severity of the problem by supporting and developing a group of tools，apps and approaches intended to prevent scammers from getting through.Unfortunately，it's too little，too late.By the time these "solutions" become widely available，scammers will have moved onto cleverer means.In the near future，it's not just going to be the number you see on your screen that will be in doubt.Soon you will also question whether the voice you're hearing is actually real.
   That's because there are a number of powerful voice manipulation（處理） and automation technologies that are about to become widely available for anyone to use.At this year's I/O Conference，a company showed a new voice technology able to produce such a convincing human-sounding voice that it was able to speak to a receptionist and book a reservation without detection.
   These developments are likely to make our current problems with robocalls much worse.The reason that robocalls are a headache has less to do with amount than precision.A decade of data breaches （數(shù)據(jù)侵入） of personal information has led to a situation where scammers can easily learn your mother's name，and far more.Armed with this knowledge，they're able to carry out individually targeted campaigns to cheat people.This means，for example，that a scammer could call you from what looks to be a familiar number and talk to you using a voice that sounds exactly like your bank teller's，tricking you into "confirming" your address，mother's name，and card number.Scammers follow money，so companies will be the worst hit.A lot of business is still done over the phone，and much of it is based on trust and existing relationships.Voice manipulation technologies may weaken that gradually.
   We need to deal with the insecure nature of our telecom networks.Phone carriers and consumers need to work together to find ways of determining and communicating what is real.That might mean either developing a uniform way to mark videos and images，showing when and who they were made by，or abandoning phone calls altogether and moving towards data-based communications-using apps like FaceTime or WhatsApp，which can be tied to your identity.
Credibility is hard to earn but easy to lose，and the problem is only going to get harder from here on out.

1．    Reading is a complex and crucial skill that impacts the youth's ability to perform as students.Therefore，it's important to develop reading skills during childhood.A team of researchers focused on the effect of whole-body learning in instruction，known as embodied learning.
    The research included 149 children，aged 5 to 6，who had just started school.They were divided into three groups：one that stood up and used their whole bodies to shape letter sounds；a seated group that shaped letter sounds with their hands and arms；and a control group that received traditional，seated instruction during which they wrote letters by hand.
    "Our research showed that children who used their whole bodies to shape the sounds of letters became twice as proficient at letter sounds that are more difficult to learn as those who received traditional instruction" says PhD student Linn Damsgaard of UCPH's Department of Nutrition，Exercise and Sports.
    With regard to difficult letter sounds，she adds， "There are many difficult letter sounds in Danish.These sounds are particularly important because once children become skilled at them，they will be better readers.
    Associate professor Jacob Wienecke，who led the study，explains，the primary goal is to learn more about which methods can be used to give beginner readers a good start.The idea is that if，through play and movement，we can learn where their strengths truly lie，we'll create a form of learning that combines reading with play，and that's truly positive."
    Previously，the researchers showed that the children felt more motivated by teaching methods which included physical movement.Jacob Wienecke hopes this will provide an opportunity to inspire teachers and school managers to prioritize movement across subjects.
    The study also investigated whether a direct effect of embodied learning could be found on children's reading of words.This was not possible，which might be due to the fact that the children were at such an early stage of their literacy development that they could not yet use their knowledge of letter sounds to read words.

（1）What were the participants required to do in the study？

A．To pick out difficult letter sounds in Danish.
B．To learn new letters through repeated writing.
C．To learn letter sounds using different approaches.
D．To memorize some letter sounds as soon as possible.
（2）How can embodied learning get children actively involved？

A．By combining learning with games.
B．By offering them chances to cooperate.
C．By inspiring them to overcome difficulties.
D．By explaining instructions to them patiently.
（3）What does the underlined word "proficient" in Paragraph 3 probably mean？

A．terrible.
B．skilled.
C．delighted.
D．fascinated.
（4）What does Jacob expect of the research finding？

A．Encouraging educators to apply it to teaching.
B．Enabling researchers to carry out further studies.
C．Urging schools to pay attention to physical exercise.
D．Promoting harmonious teacher-student relationships.
（5）What does the last paragraph intend to tell us？

A．Children prefer learning step by step.
B．Children are too little to use their knowledge smartly.
C．Children lack enough practice to get fully improved.
D．Children's learning still relies on adults' instruction.

2．How to Work Out Your Worries by Writing
Something troubling you？You should write about it!Research indicates that people who write about a difficult situation often show improved mental and physical health.
   （1）

.It is a specific technique，and it's different from writing in a journal.The idea is to reflect honestly and thoughtfully on a particular challenge.
   Hundreds of studies over several decades have looked at the potential benefits of expressive writing.It can strengthen the immune system，including for people with illnesses such as flu，cancer and depression. （2）

   Expressive writing works because it allows you to make meaning out of a painful experience，experts say. （3）

Then translating that experience into language forces you to organize your thoughts.And creating a narrative gives you a sense of control.
   But expressive writing isn't a magical cure-all solution. （4）

.And people coping with a severe injury or depression may not find it useful to do on their own，without therapy （治療）.
   （5）

？Thinking or talking about an event can lead to reflecting，where you become lost in your emotions.Writing forces you to slow down.The mere act of labeling a feeling—of putting words to an emotion—can lessen the nervous activity in the threat area of the brain.Writing can increase someone's acceptance of his experience，and acceptance is calming.

A．Why write
B．What if you don't write
C．It can also help improve mood，sleep and memory
D．Expressive writing gave people the courage to face fears
E．It shouldn't be used as a replacement for other treatments
F．The first important step is to recognise what it is that is bothering you
G．Psychologists refer to writing about an unpleasant experience as "expressive writing"

3．At some time in your life you may have a strong desire to do something strange or terrible．However，chances are that you don't act on your impulse （沖動(dòng)），but let it pass instead You know that to commit the action is wrong in some way and that other people will not accept your behavior．
