1 . Sunstroke is a condition that can quickly go from dangerous to deadly, especially if proper care isn’t given immediately.

Sunstroke, sometimes called heatstroke, is a result of the body temperature rising above the safe limit. This causes the body’s necessary functions to stop working.

It’s usually pretty easy to avoid sunstroke, as long as proper action is taken. In that case, you need to act as quickly as possible to return that person’s body to a safe temperature. Here are a few tips to help treat sunstroke.

Call for help

Call to get an ambulance as quickly as possible. This should be the first thing you do, especially if the sunstroke person has fainted (昏倒)。Also, call for help from anyone nearby if you’re in a public place. If there’s no one around, call someone nearby if they can get there sooner than an ambulance. Ask everyone to bring you as much water as possible, if there isn’t much nearby.

Get the person to a cooler area

If there’s a building nearby, aim for that. Anywhere with plenty of air conditioners and water is perfect. If a building isn’t available, bring the person to a well-shaded area.

Get the water flowing

If the person is still conscious, get him or her to drink water. If there’s a bathtub available, fill it with cool water and put the person in it.

If your water supply is limited, you have to save it. Dampen a towel or shirt and put it on the person’s body. Focus on the face, neck, and chest.

Fan the person

Getting moving air over the person cools him or her down. Use anything, a towel or sheet, a shirt, your hands, or a piece of board. This is where having many people around really helps, as they can combine to fan the entire body.

3 . Japan is known to have higher than average rates of stomach cancer. Recently, the town of Kaneyama in Yamagata Prefecture decided to get its 6, 000 residents (居民) tested.

However, the frozen urine samples (尿样) are not tested in conventional ways. Instead, Professor Masao Miyashita and his team are using them in a trial to determine if specially trained cancer-sniffing dogs can accurately detect the disease. Though the study is still in its early stages, Miyashita is thrilled with the results. He said, “In our research so far, cancer detection dogs have been able to find signs of cancer with an accuracy of nearly 100 percent.”

Researchers have known about the animals’ superior sensory skills for decades. However, their ability to detect cancer in humans came to light in 1989, after a dog sniffed out early-stage malignant melanoma (恶性黑色素瘤) on a patient’s leg in London. Since then, scientists from many countries have conducted studies to test dogs’ great skill at identifying cancer chemicals.

While most dogs can be trained for the task, researchers say the best candidates are dogs that are precise, quiet, and perhaps even a little shy. The training process is similar to how dogs are taught to learn any trick — by rewarding them with treats! However, it takes much longer because the dogs have to learn to separate the “cancer scent (气味)” from the thousands of organic compounds (有机化合物) in the human body. Researchers begin by exposing the dogs to urine samples from people with cancer, people with other diseases, and patients with no health issues, Once the dogs are able to accurately identify cancer, they are further trained to detect particular kinds of cancer.

Successful as they may be, experts think dogs are unlikely to replace conventional tests. For one, it takes about seven years and costs as much as $45,000 to train a single dog. Klaus Hackner, a researcher and physician who studies dogs detecting cancer in breath samples at Krems University Hospital in Austria, is also not convinced dogs can be relied upon alone. Patients, therefore, have to receive further tests to confirm if they have the disease.

4 . Robotic surgery is one thing, but sending a robot inside the body to carry out an operation is quite another, which has long been a goal of some researchers to produce tiny robotic devices being capable of traveling through the body to deliver drugs or to make repairs without the need for a single cut, the possibility of which has just got a bit closer.

However, unlike the plot of one film—which featured a microscopic crew and submarine traveling through a scientist's bloodstream—this device could not be put into blood vessels because it is too big. While other types of miniature swallow able robots have been developed in the past, their role has mostly been limited to capturing images inside the body. In a presentation this week to the International Conference, Daniela Rus and Shuhei Miyashita of the Massachusetts Institute of Technology described a robot they have developed that can be swallowed and used to collect dangerous objects accidentally taken in.

To test their latest version, Dr. Rus and Dr. Miyashita designed a robot as a battery hunter, which might seem to be an odd task, but more than 3,500 people in America alone, most of them children, swallow the tiny button cells used in small electronic devices by accident every year. To start with, the researchers created an artificial esophagus (食道) and stomach made out of silicone. It was closely modeled on that found in a pig and filled with medical liquid; the robot itself is made from several layers of different materials, including pig intestine (肠),and contains a little magnet. This is folded up and wrapped in a 10mmx27mm capsule of ice. Once this reaches the stomach, the ice melts and the robot unfolds which is moved and guided with the 1se of a magnetic field outside the body. In their tests, the robot was able to touch a button battery and draw it with its own magnet, and during dragging it along, the robot could then be directed towards the intestines where it would eventually be gotten rid of through the anus (肛门). After it, the researchers sent in another robot loaded with medication to deliver it to the site of the battery bum to speed up healing.

The artificial stomach being transparent (透明的) on one side, the researchers can see the batteries and visually control the robots. If not, that will require help with the help from imaging system, which will be a bit more of a challenge, but Dr. Rus and Dr. Miyashita are determined to succeed.

5 . Phototherapy （光线疗法）is a type of medical treatment that includes exposure to light bulbs or other sources of light to treat certain medical conditions. There are different types of phototherapy and various techniques.    1    

Phototherapy has been used to treat medical conditions since as far back as 3,500 years ago when the Egyptians and Indians used sunlight to treat skin conditions.    2     Widely regarded as the founder of modern phototherapy , he treated a skin condition called lupus vulgaris with sunlight and ultraviolet （紫外线）radiation. From then on, usage of phototherapy in medical fields grew, techniques were refined and developed, and it eventually gained widespread acceptance.

    3     This means it's not a permanent treatment and you may have to receive many follow-up treatments—also known as maintenance therapy—of it over your lifetime to maintain （维持）the results.

When used for skin conditions, phototherapy is generally considered safe.     4    Also there are some long-term side effects associated with it, the most serious of which are skin cancer and premature skin aging.

    5     However, you should consult with your doctor before you attempt to use it at home to ensure you're using it right, getting the most benefits with the least side effects.

A．phototherapy also has its limitations and shortcomings.

B．In this case, you are advised to stop using it immediately.

C．Phototherapy is a great choice for treating many conditions.

D．Which type to use depends on the condition that is being treated.

E．The effects of phototherapy for skin disorders are usually temporary.

F．However, short-term side effects are redness, dry skin and blisters （疱）.

G．Modern phototherapy, using artificial light sources, began with Niels Ryberg Finsen.

6 . One of the important, but seldom-discussed, problems in healthcare reform is how to take care of our aging population as people continue to live longer. According to a new study from the MacArthur Research Network on an Aging Society, by 2050 Americans may live 3.1 to 7. 9 years longer than the government expects. That would mean women would live 89 to 93 years and men 83 to nearly 86 years. The researchers base their conclusion on "rapid advances in biomedical（生物医药）technology that delay the start and progression of major deadly diseases or that slow the aging process・”

While this is good news, especially for the young, the life expectancy, which is in excess of（超过）the government's estimates, would raise costs sharply for Medicare and Social Security. If the study's predictions are accurate, the total cost for those two programs through 2050 could be between $ 3. 2 trillion and $ & 3 trillion higher than the US Census Bureau（人口普查局）and the Social Security Administration currently expect.

And that's only the beginning. With anticipated scientific breakthroughs in coming decades, people could eventually live to 150 years of age, says Dr. Steven Joyal, an official of the Life Extension Foundation (LEF) a nonprofit organization that promotes research on how we can live longer and healthier. The MacArthur paper, in fact, says that some experts believe the average life expectancy could hit 100 by 2060.

What's more, Joyal says, the conquest（战胜）of disease and the slowing of the aging process will lead to a sharp decline in disability, allowing people of advanced age to function as well as they did when they were much younger. "In other words, a 90-year-old person could have the same mental and physical capacity as somebody 40 or 50 years old."

1. What does the new study show?

A．Americans will live much longer by 2050 than they do now.

B．Great progress has been made in the US in public security.

C．Few people pay attention to the health care reform in the US.

C．Healthcare reform.

D．New research in health cam.

3. What problem may a longer life expectancy in the US lead to?

A．The aging process will speed up.

B．It adds to the chance of being disabled.

C．The old will have some mental problems.

D．It will increase public costs for the government.

4. Which of the following can be the best title for the text?

A．Life for Senior Citizens in the US

B．The Longer Life Expectancy in the Future

C．The Disadvantage of Longer Life Expectancy

D．What Can Be Done to Support So Many Aged People

7 . Imagine going to the doctor to get treatment for a terrible fever.     1     The robot detects (检测) the cause of your fever, travels to the appropriate system and provides medication directly to the infected area.

    2     They’re called nanorobots (纳米机器人) and engineering teams around the world are working to design robots that will eventually be used to treat everything from fever to cancer.

In recent years researchers have been building nanorobots out of a familiar material—the same stuff that makes human life possible.     3     DNA is literally all around (and in) you —you just can’t see it. If you were to look inside almost any cell inside any living creature, you would find DNA.

This might sound surprising—especially since these nanorobots don’t need batteries or any power source. Instead, they work by using the natural structure of DNA. These nanorobots “crawl” on DNA. Sometimes researchers refer to these things as DNA “spiders”.     4     A nanorobot could, perhaps, destroy just a cancerous cell, for example, but leave healthy cells alone.

    5     But the future is bright for DNA-built nanorobots. One day, perhaps DNA-made machines will swim around in the human body, delivering medicine to diseased cells or helping doctors diagnose problems. Or maybe they’ll help build the smallest computers the world has ever seen.

A．These nanorobots are made of DNA.

B．Nanorobots made from DNA aren’t useful yet.

C．In other words, the DNA nanorobot destroys the track as it goes.

D．This description will give you a simple picture of the legs of a DNA nanorobot.

E．Being able to make such a tiny thing move in a certain way might be useful for health.

F．Instead of giving you a pill or a shot, the doctor puts a tiny robot into your bloodstream.

G．In fact, we’re not that far off from seeing devices like this actually used in medical procedures.

8 . 阅读下面材料，在空白处填入适当的内容（1个单词）或括号内单词的正确形式。

High quality technologies, strong teamwork and humanistic care have contributed to the successful treatment of a     1     (critical) ill COVID-19 patient at the First Affiliated Hospital of Guangzhou Medical University in Guangdong province.

The novel coronavirus patient survived after     2     world record 111 days on an extracorporeal membrane oxygenation machine（体外膜肺氧合机）. The patient,     3     also had relied on a respirator to breathe for over 150 days, was discharged from the hospital last Thursday.

Zhong Nanshan, a top respiratory disease expert and an academician at the Chinese Academy of Engineering, said many of his foreign counterparts said it was a     4     (medicine) "miracle" for a seriously ill COVID-19 patient to recover after being on an ECMO for 111 days.

Zhong said they never gave up on the man, "As long as there is a glimmer of hope we do it     5    all costs," Zhong said.

ECMO is a machine     6     (use) to replace heart and lung function in open-heart surgery. In simple     7     (word), it allows the heart and lungs to rest, by pumping and oxygenating a patient's blood outside the body.

The patient, who was transferred to the First Affiliated Hospital of Guangzhou Medical University from another local hospital on Feb 4,     8     (send) to the intensive care unit and connected to the ECMO on Feb 9 when his condition     9     (worse). In addition to providing medication, the medical staff took turns caring for and looking after him in the ward.

Liu Xiaoqing, director of the hospital's intensive care medicine unit, said     10     preserving life is the most basic requirement, medical staff also should have the patient's future in mind. "We should not only enable them to live, but also live with quality," she said.
