Police around the world have for almost 100 years relied on lie detectors to help spot criminals. But there has long been much skepticism in the scientific and legal communities about the lie detector’s reliability. Hopefully, it could soon be no longer in use.

Researchers in Britain and the Netherlands have made a breakthrough, developing a　 more　 reliable method to help conduct interviews. Rather than just record changes in pulse, blood pressure, sweating and breathing, the new system involves monitoring full-body motions to provide an indicator of signs of guilty feelings.

There is a basic fact that liars tend to keep moving their hands and feet and so an all-body motion suit　 will pick this up. The suit contains 17 sensors that record movement in 23 joints up to 120 times per second.

“The lie detector has been around since the 1920s and by measuring physiological stress caused by anxiety, you can only get a success rate of about 60%.”, said Ross Anderson, professor of security engineering at Cambridge University.

He said the new method, by contrast, achieved a reliability rating of over 70% and he was quite sure that they would be able to do better. In one of their experiments, the team has already achieved more than 80%.

The experiment involved 180 students and employees at Lancaster University, of which half were told to tell the truth and half to lie. They were each paid ￡7.50 for their participation in the 70-minute experiment, involving two test.

Some were interviewed about a computer game “Never End” that they played for seven minutes, while others lied about playing it having only been shown notes about it.

The second test involved a lost wallet containing ￡ 5. Some were asked to bring the wallet to a lost-and-found box while others hid it and lied about it.

“Overall, we correctly classified 82.2% of the interviewees as either being truthful or dishonest.”, the report said.

But the use of all-body suits is expensive — they cost about ￡30,000 — and can be uncomfortable, so Anderson and his colleagues are now looking at low-cost alternatives.

1.The researchers used the all-body motion suit to 　　 .

A. discover people’s joint problems

B. record people’s changes in their health

C. help find out interviewees’ mental activities

D. prevent liars from moving their hands and feet

2.What is the main disadvantage of the lie detector?

A. It has a low success rate　　 B. It is very uncomfortable

C. It is too complex to use　　 D. It costs a lot of money

3.How does Anderson feel about the new method?

A. Confused　　 B. Confident

C. Doubtful　　 D. Disappointed

Captain America and Blackpanther were about to defend Earth from the criminal Thanos when Kevin Foley first noticed something was wrong. Foley, a 46-year old information-technology worker from Kyle, Texas, was heading into the theater to see Avengers: Infinity War when he realized he was having trouble breathing normally. The same symptom struck again during another movie the following night, but more severe this time. Once the cast on the second film rolled, Foley took action: he looked at his wristwatch. It was a bigger step than you might imagine, because Foley was wearing an Apple Watch equipped with medical sensors and experimental software to track basic functions of his heart. And the watch was worried. It had, according to the display, detected signs of an irregular heartbeat.

Before long, Foley was in an emergency room, where doctors hooked him up to an ECG (心电图), which showed that he was in atrial fibrillation (心房颤动), an irregular heartbeat that can lead to blood clots (血栓), stroke and other potentially disastrous diseases. Foley spent the next few days in the hospital while doctors worked to return him to a normal heart rhythm eventually turning to a procedure called electrical cardioversion to shock his heart back to normal. Foley is doing fine now. But he believes that, if not for the warning on his watch, he might not have sought help in time. “I would have never known,” he says.

Foley and his watch were part of an experiment run by Apple and Stanford’s medical school. But beginning from Dec. 6, anyone can get an on-the-fly heart checkup, assuming they’ve paid $399 or more for an Apple Watch. That’s when Apple will launch a software update that turns its latest model, called the Series 4, into a personal ECG, thanks to an innovative new sensor. Though less complicated than hospital ECG machines, the watch version can still provide basic information and warnings of potential risks worthy of a closer look by a medical professional.

1.What was Foley doing when he realized his heart condition was abnormal for the first time?

A.He was working in the theatre.

B.He was detecting his watch.

C.He was on the way to see a film.

D.He was equipping his Apple Watch with a medical sensor.

2.How can Foley’s wristwatch detect signs of an irregular heartbeat?

A.By being hooked straight up to an EGG in an emergency room.

B.By being equipped with an innovative new medical sensor.

C.By being paid not less than $399 for the latest Apple Watch.

D.By being accessible to Food and Drug Administration clearance for the heart monitor.

3.According to the passage, if someone wants to get an on-the-fly heart checkup, he or she________.

A.can buy a new Apple Watch Series 4

B.can purchase an Apple Watch of any model

C.can equip himself/herself with an ECG machine

D.can have his or her old Apple Watch updated

4.In which section of a newspaper may this text appear?

A.Entertainment. B.Sports.

C.Education. D.Health.
