A new study suggests the Apple Watch was able to identify abnormal heart rates that could be linked to a serious heart condition.

More than 400,000 Apple Watch users volunteered for the study. It was a project of researchers at the Stanford University School of Medicine. Apple, the American technology company, provided money for the study. Results were recently presented at a major conference on heart health in New Orleans, Louisiana.

The researchers looked for signs of atrial fibrillation, also called “a-fib”, the most common form of irregular heartbeat. Some people with a-fib feel changes in their heartbeat, while others do not. Because of this, many people do not know they have the condition. People with untreated a-fib are about five times more likely to suffer a stroke. In the United States, a-fib causes an estimated 130,000 deaths and 750,000 hospitalizations each year.

People taking part in the study wore the Apple Watch for extended periods. The devices contain an app that continuously gathers information without users having to do anything. It uses the watch’s light sensor technology to measure blood flow. The system is designed to identify changes that might show an irregular heartbeat.

The researchers said that out of those taking part, about 2,000 subjects received a warning from the device that they might have a problem. Those individuals were then asked to contact a doctor, who decided whether they should receive more close watch for a possible irregular heartbeat.

Lloyd Minor, head of Stanford’s School of Medicine, said in a statement that the results show great promise in using technology to create “more predictive and preventive health care”. Doctor Minor added that a-fib is just one example of a condition devices can help identify in the future. “This study opens the door to further research into wearable technologies and how they might be used to prevent disease before it strikes,” he said.

But some health researchers warned against making any general judgements based on the Apple-financed study. They have called for much more research to measure the effectiveness of wearable devices to identify signs of disease. Richard Kovacs, who was with the American College of Cardiology and was not involved with the study, told the Associated Press that despite the results, the Apple Watch system “is not perfect.” He noted that since the study did not have a comparison group getting regular ECG measurements, there is no way of knowing if the device missed heartbeat problems. This could give users a false sense of security, he said.

Other experts agreed that more studies are needed before similar device-based health observation systems are widely recommended.

1. What does the new study mainly find out?
A.Apple Watch can warn of heart problems.B.Apple Watch can protect people against a-fib.
C.Abnormal heart rates can cause a stroke.D.Heart problems can be identified and cured.
2. Apple Watch identifies irregular heartbeats by _____.
A.measuring the wearer’s heart ratesB.sending information to the wearer through an app
C.extending the time of wearing itD.monitoring the wearer’s bloodstream
3. Which of the following might be what Lloyd Minor means in his statement?
A.It’s difficult for doctors to predict and prevent disease now.
B.A-fib is just one example of a condition that causes heart problems.
C.Wearable technologies might identify and treat any disease one day.
D.There are more possibilities of development in wearable technology.
4. It can be concluded from the passage that _____.
A.wearable technologies are developing fast but shouldn’t be applied to medicine
B.the study results are inspiring but more proofs are needed to ensure the accuracy
C.the study is sponsored by a commercial company so the results are a little unfair

文章大意:这是一篇说明文。文章讲述了不同国家的人们对待精神方面的疾病的处理方法的差异。

【推荐1】At some point in life, many people develop a mental problem. While most people get over it, for others it doesn’t go away easily.

The WHO says that about 20 percent of teenagers worldwide suffer from mental illness. It’s thought that the number of teenagers with mental illness around the world will increase by half by 2022. It will become one of the main causes of illness, and even death.

In China, the picture isn’t bright, either. About one tenth of teenagers under the age of 17 have a mental health challenge.

The world is changing fast. Study and relationships have always caused stress, but today the stress is much higher than before, the WHO said.

A research centre in Oxford University says that young people today have big stresses at school. For example, they experience bullying. In a 2017 report, the centre noted that the Internet was a special source of stress. Online, young people often see “messages about perfection” and this causes the young “great uncertainty about their futures”, says the centre.

Also, according to China Daily, Chinese people don’t ask for help with their mental problems. They fear that others will think less of them if they say that they are in mental trouble. Elaine Peng, a US mental health educator, makes a similar point. And in the UK, over three quarters of young people believe their mental problems have a social stigma. It is reported in 2017 that a quarter of young UK people wouldn’t ask for help if they developed a mental problem.

Young people who don’t ask for help for their condition may be creating problems for themselves in the future. Elaine Peng warned that, “If we hide our mental health, it may remain a problem forever.”

“My message for young people is, if you feel something is wrong within you—ask for help,” he told China Daily.

1. Which of the following is NOT the cause of stress according to the passage?
A.Heavy schoolwork.
B.Being bullied at school.
C.Some information from the Internet.
D.Certainty about the future.
2. Why don’t Chinese people ask for help with their mental problems?
A.They can keep their mental health secret.
B.They can get over them in time.
C.They are afraid of being looked down upon.
D.They don’t think them serious.
3. What does the underlined word “stigma” most probably mean?
A.Impression.B.Shame.C.Aid.D.Injury.

【推荐2】It was not until I was 9 years old that I found out my father was ill. It was 1994, but I can remember my mother's words as if it were yesterday: "Kernel, I don't want you to take food from your father, because he has AIDS. Be very careful when you are around him." AIDS wasn't something we talked about in my country when I was growing up. From then on, I knew that this would be a family secret. My parents were not together anymore, and my dad lived alone. For a while, he could take care of himself. But when I was 12, his condition worsened. My father's other children lived far away, so it fell to me to took after him.

We couldn't afford all the necessary medicine for him, and because Dad was unable to work, I had no money for school supplies and often couldn't even buy food for dinner. I would sit in class feeling completely lost, the teacher's words muffled as I tried to figure out how I was going to manage. I did not share my burden with anyone. I had seen people reacted to AIDS. Kids laughed at classmates who had parents with the disease. And even adults could be cruel. When my father was moved to the hospital, the nurses would leave his food on the bedside even though he was too weak to feed himself.

I had known that he was going to die, but after so many years of keeping his condition a secret, I was completely unprepared when he reached his final days. Sad and hopeless, I called a woman at the nonprofit National AIDS Support. That day, she kept me on the phone for hours. I was so lucky to find someone who cared. She saved my life.

I was 15 when my father died. He took his secret away with him, having never spoken about AIDS to anyone, even me. He didn't want to call attention to AIDS. I do.

1. What does Kernel tell us about her father?
A.He had stayed in the hospital since he fell ill.
B.He worked hard to pay for his medication.
C.He told no one about his disease.
D.He was carefully attended by the nurses on his deathbed

3. Why did Kernel keep her father's disease a secret?
A.She wanted to obey her mother.
B.She was afraid of being looked down upon.
C.She found no one willing to listen to her.
D.She thought it was shameful to have AIDS.
4. What’s the author’s purpose in writing the text?

【推荐3】The deadliest Ebola(埃博拉病毒) outbreak in recorded history is happening right now. The outbreak is unprecedented(空前的) both in the number of people who have gotten sick and in the geographic scope. And so far it’s been a long battle that doesn’t appear to be slowing down.
Ebola is both rare and very deadly. Since the first outbreak in 1976, Ebola viruses have infected thousands of people and killed roughly killed 60 percent of them. Symptoms can come on quickly and kill fast.
The current outbreak started in Guinea sometime in late 2013 or early 2014. It has since spread to Sierra Leone and Liberia, including some capital cities. And one infected patient traveled on a plane to Nigeria, where he spread the disease to several others and then died. Cases have also popped up in various other countries throughout the world, including in Dallas and New York City in the United States.
The Ebola virus has now hit many countries, including Guinea, Liberia, Sierra Leone, Nigeria, Senegal, and the United States. The virus, which starts off with flu-like symptoms and sometimes ends with bleeding, has infected about 6,500 people and killed more than 3,000 since this winter, according to the World Health Organization on September 30, 2014.
There are some social and political factors contributing to the current disaster. Because this is the first major Ebola outbreak in West Africa, many of the region’s health workers didn’t have experience or training in how to protect themselves or care for patients with this disease.
Journalist David Quammen put it well in a recent New York Times article, “Ebola is more dangerous to humans than perhaps any known virus on Earth, except rabies(狂犬病) and HIV. And it does its damage much faster than either.”
Hopefully, researchers are working to find drugs, including a recent $50 million push at the National Institutes of Health. And scientists are working on vaccines(疫苗), including looking into ones that might be able to help wild chimpanzees, which are also susceptible to the disease. The first human Ebola vaccine trial is scheduled to start in the spring of 2015.
1. According to the passage, which of the following about Ebola is true?
A.The Ebola outbreak now is the biggest one in history.
B.Ebola breaks out quickly but it is under control now.
C.Ebola is deadly and common so it kills a lot of people.
D.Ebola killed about 60 thousand people quickly in 1976.
2. The Ebola virus was brought to Nigeria by         .
A.a flying birdB.an infected passenger
C.hot African weatherD.a health organization
3. The last paragraph mainly tells us that         .
A.it will be a huge waste when researchers spend lots of money finding a cure
B.the vaccines can be effective to wild chimpanzees but not to the humans
C.there will be an optimistic future in which we can defeat the disease
D.we can use the vaccine to cure the patients completely in 2015’s spring
4. What is the best title of the passage?
A.Ebola ---- The African Local Disaster
B.Ebola ---- The Newly-Found Disease
C.Ebola ---- A More Effective Vaccine
D.Ebola ---- The Deadly Virus Outbreak
