We discuss the issue of when to help a patient die. Doctors of our generation are not newcomers to this question. Going back to my internship（实习）days, I can remember many patients in pain, sometimes in coma(昏迷), with late, hopeless cancer. For many of them, we wrote an order for heavy medication—morphine(吗啡)by the clock. This was not talked about openly and little was written about it. It was essential, not controversial.

The best way to bring the problem into focus is to describe two patients whom I cared for. The first, formerly a nurse, had an automobile accident. A few days later her lungs seemed to fill up; her heart developed dangerous rhythm disturbances. So there she was: in coma, on a breathing machine, her heartbeat maintained with an electrical device. One day after rounds, my secretary said the husband and son of the patient wanted to see me. They told me their wife and mother was obviously going to die; she was a nurse and had told her family that she never wanted this kind of terrible death, being maintained by machines. I told them that while I respected their view, there was nothing deadly about her situation. The kidney(肾) failure she had was just the kind for which the artificial kidney was most effective. While possibly a bit reassured, they were disappointed. Here was the head surgeon seemingly determined to keep everybody alive, no matter what.

Within a few days the patient's pacemaker(起搏器) could be removed and she awoke from her coma. About six months later, the door of my office opened and in walked a gloriously fit woman. After some cheery words of appreciation, the father and son asked to speak to me alone. As soon as the door closed, both men became quite tearful. All that came out was, "We want you to know how wrong we were."

The second patient was an 85-year-old lady whose hair caught fire while she was smoking. She arrived with a deep burn; I knew it would surely be deadly. As a remarkable coincidence there was a meeting for discussion going on at the time in medical ethics(道德). The speaker asked me if I had any sort of ethical problem I could bring up for discussion. I described the case and asked the students their opinion. After the discussion, I made a remark that was, when looking back, a serious mistake. I said, "I'll take the word back to the nurses about her and we will talk about it some more before we decide." The instructor and the students were shocked: "You mean this is a real patient?" The teacher of ethics was not accustomed to being challenged by actuality. In any event, I went back and met with the nurses. A day or two later, when she was making no progress and was suffering terribly, we began to back off treatment. Soon she died quietly and not in pain. As a reasonable physician, you had better move ahead and do what you would want done for you. And don't discuss it with the world first. There is a lesson here for everybody. Assisting people to leave this life requires strong judgment and long experience to avoid its misuse.

    Rate of revolution: 35.03 km/second.

    Atmosphere:

    Very thick.

    96% carbon dioxide; 3% nitrogen, and 0.1% water vapor.

    Can't support life: Suffocating carbon dioxide, thick clouds of sulfuric acid, and gases create greenhouse effect so very hot and no water.

    Nowadays, especially in China, everything seems to favor social intercourse, such as gatherings of friends, KTV, group travel, dining togethter, playing cards and Mahjong, plus the Chinese-style “street-crossing group.” Back home, discussions can still be boisterously carried on within the “circle of friends” of WeChat.

      However, these scenes cannot always ease a sense of loneliness. Zhu Ziqing, a well-known professor of Tsinghua University, signed with emotion: “My loneliness increases as scene becomes much busier.” One popular song today is also called “A lonely man in crowds.” Actually, engaging in social intercourse requires ability, while being alone involves the whole character.

    These days, it is not easy to calm down totally and return to one's true self. Willpower, intellect and discipline are required. Einstein said: “It is not your working time but your spare time that determines the possibility of whether you will be successful or not.” The “spare time” he referred to could be taken as “spending time by yourself.”

    Lonely life could be either dull, boring and tasteless or abundant, interesting and colorful, depending on one's quality, ambition and inspiration.

    Just as the body constantly requires energy, the mind and soul also demand unceasing inputs. However, information, to processed and integrated(融入)into knowledge, thoughts and feelings, instead of bustle(忙碌)seems to be the right condition. Successful careers in all walks of life worldwide have proved that “the soul grows in peace and talent is nurtured in loneliness”. In a sense, it may be reasonable to say that “Happiness tends to be shallow while loneliness involves profundity”.

    Man, in fact, needs loneliness more than happy time, and only abundant loneliness can produce quality happiness.

    Humans and many other mammals have unusually efficient internal temperature regulating systems that automatically maintain stable core body temperatures in cold winters and warm summers. In addition, people have developed cultural patterns and technologies that help them adjust to extremes of temperature and humidity (湿度).

In very cold climates, there is a constant danger of developing hypothermia, which is a life-threatening drop in core body temperature to below normal levels. The normal temperature for humans is about 37.0℃. However, differences in persons and even the time of day can cause it to be as much as 6℃ higher or lower in healthy individuals. It is also normal for core body temperature to be lower in elderly people. Hypothermia begins to occur when the core body temperature drops to 34.4℃. Below 29.4℃, the body cools more rapidly because its natural temperature regulating system usually fails. The rapid decline in core body temperature is likely to result in death. However, there have been rare cases in which people have been saved after their temperatures had dropped to 13.9-15.6℃. This happened in 1999 to a Swedish woman who was trapped under an ice sheet in freezing water for 80 minutes. She was found unconscious, not breathing, and her heart had stopped beating, yet she was eventually saved despite the fact that her temperature had dropped to 13.7℃.

In extremely hot climates or as a result of uncontrollable infections, core body temperatures can rise to equally dangerous levels. This is hyperthermia. Life-threatening hyperthermia typically starts in humans when their temperatures rise to 40.6-41.7℃. Only a few days at this extraordinarily high temperature level is likely to result in the worsening of internal organs and death.

    Educators across the US are calling for major changes to the admissions process in higher education. The Harvard school of Greduate Education, along with 80 other schools and organizations, released a report called "Turning the Tide Making Caring Common” in January, 2016. The report argues that the process schools use to choose students causes major problems.

    David Hawkins is the Executive Director for Educational Content and Policy at the National Association for College Admissions Counseling. Hawkins told Voice of America that most colleges and universities require many things from students when they apply. Schools usually ask for an essay describing a student's interests or why they want to study at that school. The schools also ask for letters from teachers or other responsible adults describing why a student is a good candidate. But, Hawkins says, the area that schools are most concerned about is a student's high school grades and standardized test results.

    The report suggests that paying attention to academic success over other qualities works well for some students but hurts others. In addition, academic success is not the most important quality a student should have. More attention should be paid to showing whether or not a student wants to do well in the world, according to the report.

    The report goes on to state that the best way to change the admissions process is by changing college applications. It suggests that schools should ask for evidence that students care about other people. But the report does have its critics. Bob Schaeffer, Public Education Director for the National Center for Fair and Open Testing, said that every few years, someone makes the same argument for changes, but no real change has happed yet. Even many of the schools that agree with the report still make no changes.

    Lloyd Thacker, Executive Director of the Education Conservancy, said that until a majority of schools agree to make the changes, there will still be problems. However, he said, the admissions process was better in the past. If bad changes can affect the process, so can good ones.

    The Taj Mahal, in Agra, India, is one of the most brilliant structures on Earth. It is nearly 400 years old. Emperor Shah Jahan had it built in memory of his wife. It took about 20 years to build the monument. Some 20,000 workers and 1,000 elephants helped get the job done. Today, the Taj Mahal is not just a symbol of cultural history. It's also India's most famous tourist attraction. About 8 million people visit it each year.

    But pollution is turning the white marble monument shades of green, yellow, and brown. The Taj Mahal stands on the polluted Yamuna River. Insects are attracted to the dirty water. They leave greenish droppings on the building. Air pollution is also a big threat. Factories and cars release pollution into the air. It sticks to the Taj Mahal's suidEace. In the 1990s, India's Supreme Court ordered hundreds of factories near the monument to close. Also, car and bus traffic was restricted. From time to time, workers clean the Taj Mahal. But doing so is difficult, expensive, and time-consuming. And it doesn't prevent the discoloration.

    On July 11, India's Supreme Court gave the city of Agra a warning: "Either you destroy the Taj Mahal or you restore it". Authorities in the city submitted a draft of an action plan on July 24. It suggests banning plastics and construction from the area. It also calls for the closing of more factories.

    "In order to preserve the Taj Mahal, people must come together to work toward a solution. There needs to be positive pressure on people to act. We need to act immediately," Sachchida Tripathi says. He worked on a 2014 study of pollution at the Taj Mahal. "We are trying," he adds, "but we need to try more."
