1 . In the 12th century, physician Ibn Zuhr conducted some animal research to assess the surgical procedures that could be applied to humans. Since then, animal testing has been considered the most efficient way to develop new drugs. New medical treatments and drugs are tested on animals first to determine their effectiveness or safety levels before they are finally tested on humans. However, it remains controversial whether it is morally right or wrong to use animals for experiments.
The use of animals for medical purposes is seen to be necessary by many scientists. Researchers usually begin their trials using rats. If the tests are successful, further tests are done on monkeys before using human beings. For testing, such tiered(分层的) rounds are important because they reduce the level of error and negative side effects. Some argue that animal testing has contributed to many life-saving cures and treatments and there is no adequate alternative to testing on a living, whole-body system. Moreover, there are regulations for animal testing that limit the misuse of animals during research. They serve as evidence that animals are well taken care of and treated well instead of being intentionally harmed.
However, some other experts and animal welfare groups have opposed such practice, considering it as inhumane(不人道的) and claiming it should be banned. According to Humane Society International, animals used in experiments are commonly subjected to force-feeding, radiation exposure, operations to deliberately cause damage and frightening situations to create depression and anxiety. They also hold the view that animals are very different from human beings and therefore are poor test subjects. Drugs that pass animal tests are not necessarily safe. Animal tests on the arthritis (关节炎) drug Vioxx showed it would have a protective effect on the hearts of mice, yet the drug went on to cause about 27,000 heart attacks before being pulled back from the market.
It’s safe to say that using animals for tests will continue to be debated in many years to come. Despite the benefits of animal testing, some of the concerns need to be addressed with adequate regulations to ensure that animals are treated humanely.

2 . 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 . About 600,000 people die of heart attacks at home each year. And the survival rate (存活率) of out-of-hospital heart attacks is much lower than those that happen at the in-hospital setting.
Pumpstart, a program created by students at Boston University School of Medicine (BUSM) which is meant to teach hands-only CPR (心脏复苏术) to the general public, is effective in both teaching high school students a life-saving skill and providing medical students with a chance to take part in public health and medical education after several surveys.
High school students in the Boston area who joined in the Pumpstart program completed pre-/post surveys. The pre-surveys were carried out before they watched a 60-minute training session (培训课程) on hands-only CPR. And the post surveys were done after the training session. Medical students also completed surveys judging their comfort in learning CPR both before and after they took part in the program. The high school students reported huge improvements in CPR skills following their training from Pumpstart. And it was reported that the medical students had higher confidence levels regarding their abilities to answer questions about CPR and helping new medical students to better understand the training sessions after they joined in Pumpstart.
“Getting the general public to feel comfortable performing CPR is important to overall improved survival from heart attacks,” explained Anita Knopov, a fourth-year medical student at BUSM. “Using educational resources provided by the city medical center and offering training to inner-city high school students allow medical students to serve as both educators and experienced people in CPR within the community, while making high school students interested in the healthcare field (医疗领域). That’s what Pumpstart does.”
Knopov believes Pumpstart can serve as a model for other organizations and can have a long-term (长期的) public health influence as the bystander CPR continues to be one of the most useful factors in out-of-hospital (医院之外) heart attack survival. “Although Pumpstart is offered only in Boston, we hope that our work may stimulate the development of similar programs in other areas. And in that case we can use lots of new ‘Pumpstarts’ in other regions.”
1. What is the main purpose of Pumpstart?| A．To change people’s lifestyle. |
| B．To train students to be healthy |
| C．To improve CPR skills of the public. |
| D．To provide medical care for communities. |
| A．Pumpstart improves students self-confidence |
| B．Pumpstart performs CPR for people independently. |
| C．Pumpstart obviously reduces the risk of heart attacks |
| D．Pumpstart encourages students to work in the healthcare field |
| A．Pretty useful. | B．Widely popular |
| C．Partly confusing. | D．Fairly interesting |
| A．Check | B．Prevent |
| C．Encourage | D．Slow |
4 . Getting sick is a common part of people’s lives. But their attitudes toward being sick and hospital visits vary from country to country. This difference hasn’t been more obvious since the start of the novel coronavirus epidemic — when a great number of people are falling ill all at the same time.
The conditions in the US are getting worse quickly, which is largely due to the fact that there’s no universal health-care system. According to the 2019 US Census, 28 million people are not covered or do not have adequate health insurance, meaning that they would probably avoid getting tested for the virus, for fear of the cost of being hospitalized.
‘‘There is a strong financial reason to hide symptoms, to try to keep working and caring for children, and thus, they’re spreading the virus … simply because they have no other choice.” wrote reporter James Hamblin on The Atlantic.
Germany, on the contrary, has one of the world’s best-developed public healthcare systems that covers every citizen. People in Germany — who have ‘‘high levels of job security’’, according to the Los Angeles Times — are also more likely to follow the separation measures and stay at home without having to worry about losing their jobs.
Japan also has universal public health-care, but it brings another kind of problem: People tend to seek more medical care than necessary. According to Yusuke Tsugawa, a physician at Harvard University, Japan has three times more outpatient (门诊) visits than in the US, and patients also stay in hospital for three times longer than in the US. This often wastes medical resources, which are even more critical and precious during a global pandemic.
‘‘It isn’t good to do tests just to ease public anxiety,” Kentaro Iwata, an infectious disease expert at Kobe University, Japan, told Reuters. ‘‘If they test everyone with light symptoms, the medical system will break down.”
Indeed, a country’s healthcare system is the key to keeping its people safe - it’s also the key to whether a country can survive a crisis like the novel coronavirus pandemic.
1. Why are the conditions in the US worsening rapidly?| A．All people there avoid getting tested. |
| B．Most people there don’t have health insurance. |
| C．Most people there can’t afford being hospitalized. |
| D．All people there are not covered by health-care system. |
| A．They choose to do so. | B．They don’t want to work alone. |
| C．They are concerned about money. | D．They want to stay with their children. |
| A．They have too many outpatient visits. |
| B．They waste too much time on unnecessary testing. |
| C．They spend too much money on public health-care. |
| D．They don’t make the best use of medical resources. |
5 . Did you know it's possible to swim with whales in the ocean while lying on a hospital bed? Have you imagined experiencing your 74t birthday as a 20-something? Medical virtual（虚拟的）reality is an area with interesting and attractive possibilities. Although the field is brand new, there are already great examples of VR having a positive effect on health care. Here are some.
Have you ever lain down on a hospital bed counting the days until you leave the hospital? Brennan Spiegel and his team at the Cedars-Sinai hospital in Los Angeles introduced VR worlds to their patients to help them reduce stress and pain. With the special glasses, they could escape the four walls of the hospital and enjoy amazing scenery in Iceland, take part in the work of an art studio or swim together with whales in the ocean. So the hospital experience is improved.
As we know, the experience in a hospital is even more stressful for small children who miss their parents and friends. Now, a Dutch company made their dream possible. Through a smart phone and virtual glasses, VisitU makes live contact （实况联系） possible with a 360 degree camera at the patient's home, school or special occasions like a birthday celebration or a football game. Though staying in hospital, young patients can relax and still enjoy their lives.
Did you wonder what it feels like to grow old? Embodied Labs created "We Are Alfred" by using VR technology to show young medical students what ageing means. Everyone can be the imagined Alfred for 7 minutes, and experience what it feels like to live as a 74-year-old man. Thus it's possible to solve the disconnection between young doctors and elderly patients due to their huge age difference.
MindMotionPro, produced by the Swiss Mindmaze allows patients with a brain injury to "practice" how to lift their arms or move their fingers with the help of virtual reality. The app makes the practice of repetitive（重复的）movements fun for patients. The mental effort helps their damaged nervous systems to recover much faster than lying helplessly in bed.

8 . Doctors Without Borders, which was set up in 1971 by doctors and journalists in France, is a humanitarian (慈善的) organization also known as its French name, Médecins Sans Frontières, and handles emergencies caused by wars, infectious diseases and natural disasters. Today, the group provides humanitarian medical aid in more than 70 countries. Over 90 percent of its money comes from private sources. In 1999, the group received the Nobel Peace Prize.
Living in Emergency: Stories of Doctors Without Borders is a documentary by the movie director Mark Hopkins. It tells the stories of four doctors and their voluntary work in Liberia and the Democratic Republic of Congo. Mr. Hopkins and his crew filmed the doctors working under some of the most extreme and dangerous conditions.
Doctor Tom Krueger from the United States in the film volunteered in Liberia in 2003, after two civil wars. He said, “It was pretty much of a shock when I got here. You can’t describe the feeling of the heat in your body and the sweat running down your back, and the smell of the pus (脓) that hits your nose and of unwashed bodies in a closed room.”
Another doctor in the film, Australian Chris Brasheer, has been with Doctors Without Borders for nine years. He has served in the Democratic Republic of Congo and spent time in Liberia. He said, “No water, no electricity, no food — pretty apocalyptic really.”
Doctor Chiara Lepora from Italy also appears in the film. She spent several years working with the group. She said, “I will probably return. There are a lot of doctors who are willing to volunteer once, but not many doctors who are willing to repeat their experience.”

10 . Most people who know about diabetes think there are two kinds: type l, which you are born with, and type 2, which you get later in life from eating too much. This isn't quite right, since the two types can occur at different life stages and for a number of reasons, but the broad distinction is well rooted in the public's mind.
Now some doctors want to change that and break the disease down into five subtypes (子类型), each with its own set of risk factors, outcomes and treatments. The new claim was made by researchers based in Sweden and Finland who assessed almost 15,000 people with diabetes in those countries. They found that these people fell into one of five categories based on their blood sugar, insulin (胰岛素) production and sensitivity, and their body mass index and age. The subgroups also vary genetically.
The researchers say that two of the subtypes are mild and can be largely treated with lifestyle changes and small amounts of a standard drug. People with the three more severe forms are more likely to develop eye and kidney disease, so treating them is a must.
So far, so good. After all, this is the way medicine is heading. The more we learn about common diseases, the more we realize there is huge variation in the way they present themselves. For example, research into the genetics of several cancers has helped identify which treatments might work best for individuals.
The idea that a cheap and fairly straightforward blood test could help doctors predict the cause and prognosis (预断) of that individuals' diabetes is appealing. This is especially the case given that an estimated 9 percent of the global population are affected by the disorder and many aren’t getting the right treatment.
But the five subgroups aren't the end of the story. Diabetes just isn't that simple. For a long time, we considered the condition as being either “childhood-onset” or “adult-onset”, and this is how many people still think of the disease. Yet in the last decade, this classification was questioned as it was discovered that adults in their 40s and 50s could develop a form of the disease that looked very “childhood” like, while more children are developing type 2 diabetes. It is also quite likely that the risks and outcomes of diabetes will look different in people who live outside Sweden and Finland, such as in the Middle East whose nations have some of the highest rates of the condition in the world.
