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．It has happened to us all：sitting on the sofa，toying with the idea of sending an old friend an unexpected text，but worrying that a message out of the blue may seem unusual or just unwelcome.
   However，research suggests such fears are unfounded，with those on the receiving end often far more grateful than the sender may expect.Dr.Peggy Liu，the lead author of the research said the team began their research because they felt a lot of people were losing touch with each other due to their concerns or fears.
   Liu and her colleagues conducted a series of experiments，based on hypothetical（虛構(gòu)的）and real-life plots，involving more than 5，900 participants.In one experiment，54 participants wrote a note to a fellow college student they hadn't been in touch for a while.This note was emailed to the latter by the researchers，who asked both the writer and the receiver to indicate how much they felt the message was appreciated.
   The results show that on average senders rated receivers' appreciation at 5.57 on a seven-point scale，while the receivers themselves rated their appreciation at 6.17.The team said this and other experiments revealed that people receiving messages appreciate them significantly more than the sender tends to expect.
   But Liu said questions remained."While we show that people typically underestimate how much others appreciate being reached out to，it remains an outstanding question how we can actually motivate people to reach out to others more，"she said."That's what we're going to do next."
   Stephen Reicher，a professor of social psychology at the University of St Andrews，said the results made sense."If the pandemic（疫情爆發(fā)） has taught us anything，it is that we have a pandemic of loneliness causing massive harm and we need to address it urgently as a matter of public health，"he said，"Feeling connected to others has consistently been shown to be good for our physical and mental health.Such connections can be remarkably effective in everything from protecting against depression to recovery from heart attacks."He added that simply feeling part of a group was equally effective.

D．Its purpose.
（3）What does Dr.Liu suggest？

A．Interviewing the study participants.
B．Making use of the findings.

3．The Hadza hunter-gatherers of Tanzania live a life that has not changed much over ten thousand years.They have no crops，no house animals，no permanent shelters.In spite of long exposure to agriculturalist groups around them，the Hadza have maintained their lifestyle.
   The story of the spread of agriculture is the story of growing population density （密度）.Villages formed，then cities，then nations.Agriculture's rise，however，came with a price. It introduced infectious diseases，social inequality，occasional famines （饑荒） and war.Professor Jared Diamond of UCLA （University of California，Los Angeles） has called the adoption of agriculture "the worst mistake in human history"— a mistake from which we have never recovered.
   Looking at the Hadza，you can see why he came to this conclusion.They do not engage in warfare.They do not live densely （稠密地） enough to be threatened by an infectious outbreak.They have no known history of famine （饑荒）.The Hadza diet is more stable （穩(wěn)定的） and varied than that of most of the world's citizens.They live almost entirely free of possessions.They enjoy an extraordinary amount of leisure time， "working" — actively pursuing food — only four to six hours a day.
   The chief reason the Hadza have been able to maintain their lifestyle so long is that their homeland is not an inviting place.Recently，however，population growth has brought a flood of people into Hadza lands.The region has generally been viewed by outsiders as unused，a Place in need of development.The Hadza，who by nature are not a combative （好戰(zhàn)的） people，have almost always moved away instead of fighting.
   There are many things to envy about the Hadza，mostly what free spirits they appear to be.Free from schedules，jobs，bosses，bills，traffic，taxes，laws，social duties and money.But who of us could live like them？It's incredibly risky.Medical help is far away.One bad fall from a tree，one bite from a snake，and you're dead.The fact is that it's too late for us to go back to the Hadza lifestyle.Of greater concern is that soon it may be impossible for them to maintain theirs.
