A build-it-yourself solar still（蒸馏器） is one of the best ways to obtain drinking water in areas where the liquid is not readily available. Developed by two doctors in the U. S. Department of Agriculture, it's an excellent water collector. Unfortunately, you must carry the necessary equipment with you, since it's all but impossible to find natural substitutes. The only components required, though, are a 5＇  5＇ sheet of clear or slightly milky plastic, six feet of plastic tube, and a container — perhaps just a drinking cup — to catch the water. These pieces can be folded into a neat little pack and fastened on your belt.

    To construct a working still, use a sharp stick or rock to dig a hole four feet across and three feet deep. Try to make the hole in a damp area to increase the water catcher's productivity. Place your cup in the deepest part of the hole. Then lay the tube in place so that one end rests all the way in the cup and the rest of the line runs up — and out — the side of the hole.

    Next, cover the hole with the plastic sheet, securing the edges of the plastic with dirt and weighting the sheet's center down with a rock. The plastic should now form a cone(圆锥体) with 45-degree-angled sides. The low point of the sheet must be centered directly over, and no more than three inches above, the cup.

    The solar still works by creating a greenhouse under the plastic. Ground water evaporates (蒸发) and collects on the sheet until small drops of water form, run down the material and fall off into the cup. When the container is full, you can suck the refreshment out through the tube, and won't have to break down the still every time you need a drink.

    Can you imagine being paid millions for playing in a sports team? That you were able to fill stadiums with people coming to see you play? That you could attract fans crazily like a superstar? ESports have made all that possible and more. The fever for video games has had a great influence on the sports industry.

    To what degree ESports, or electronic sports can be considered a sport remains a question. If we stick to the meaning in the dictionary, sport is understood to be any physical activity, whether a game or competition, that requires training and following rules. A second meaning is: all kinds of physical activities are done for health or for fun.

    Spending hours and hours in front of a computer or with a mobile phone in hand playing video games is not a physical activity. But when the voices that defend it belong to famous athletes, and when the International Olympic Committee itself is, seriously thinking about the possibility of introducing eSports in the 2020 Olympic Games, it is at least worth considering the argument.

    It is clear that eSports has had a big influence on the sports industry and its fans are increasing all the time. Athletes, sports teams, sponsors （赞助商） inside and outside the sport, and the media support the industry greatly, which attracts and satisfies the young generation. Professional video game competitions have made nearly $900 million over the past three years thanks to sponsorship and advertising. The industry is expected to make over $1.1 billion and reach 215 million users in 2019, according to a study by the consultant Newzoo.

    The big players in the eSports leagues have turned their ‘hobby' into a profession which offers a chance to gain fame or become famous. Those guys who distance themselves from the world, shutting themselves up for up to 12 hours a day in a dark room to connect with people from all over the planet through a video game, now fill large stadiums and compete for prizes that are over one million dollars. They are the envy of half the planet!

    As a famous NBA superstar, Shaquille O'Neal says “the fans themselves are the ones who opened my eyes. ESports are a great business chance and the industry cannot be left out.”

    While millions of dollars are paid around the world for these new idols, we can continue to argue whether they are sports or not. If only for fun…

    William Butler Yeats, a most famous Irish writer, was born in Dublin on June 13, 1865. His childhood lacked the harmony that was typical of a happy family. Later, Yeats shocked his family by saying that he remembered "little of childhood but its pain". In fact, he inherited (继承) excellent taste in art from his family—both his father and his brother were painters. But he finally settled on literature, particularly drama and poetry.

    Yeats had strong faith in coming of new artistic movements. He set himself the fresh task in founding an Irish national theatre in the late 1890s. His early theatrical experiments, however, were not received favorably at the beginning. He didn't lose heart, and finally enjoyed success in his poetical drama.

    Compared with his dramatic works, Yeats's poems attract much admiring notice. The subject matter includes love, nature, history, time and aging. Though Yeats generally relied on very traditional forms, he brought modern sensibility to them. As his literary life progressed, his poetry grew finer and richer, which led him to worldwide recognition.

    He had not enjoyed a major public life since winning the Nobel Price in 1923. Yet, he continued writing almost to the end of his life. Had Yeats stopped writing at age 40, he would who probably now be valued as a minor poet, for there is no other example in literary history of a poet Auden wrote, among others, the following liners:

    Earth, receive an honored guest:

    William Yeats is laid to rest.

    Let the Irish vessel (船) lie

    Emptied of its poetry.

Unhealthy health care bills, long emergency-room waits and inability to find a primary care physician just scratch the surface of the problems that patients face daily.

Primary care should be the backbone of any health care system. Countries with appropriate primary care resources score highly when it comes to health outcomes and costs. The U.S. takes the opposite approach by emphasizing the specialists rather than the primary care physician.

A recent study analyzed the providers who treat Medicare Beneficiaries(老年医保受惠人). The startling finding was that the average Medicare patient saw a total of seven doctors — two primary care physicians and five specialists — in a given year. Contrary to popular belief, the more physicians taking care of you don't guarantee better care. Actually increasing breakup of care results in a corresponding rise in costs and medical errors.

How did we let primary care slip so far? The key is how doctors are paid. Most physicians are paid whenever they perform a medical service. The more a physician does, regardless of quality or outcome, the better he's reimbursed (返还费用). Moreover, the amount of a physician receives leans heavily toward medical or surgical procedures. A specialist who performs a procedure in a 30-minute visit can be paid three times more than a primary care physician using that same 30 minutes to discuss a patient's disease. Combine this fact with annual government threats to indiscriminately cut reimbursements, physicians are faced with no choice but to increase quantity to boost income.

Primary care physicians who refuse to compromise quality are either driven out of business or to cash-only practices, further contributing to the decline of primary care.

Medical students are not blind to this scenario. They see how heavily the reimbursement deck is stacked against primary care. The recent numbers show that since 1997, newly graduated U.S. medical students who choose primary care as a career have declined by 50%. This trend results in emergency rooms being overwhelmed with patients without regular doctors.

How do we fix this problem?

It starts with reforming the physician reimbursement system. Remove the pressure for primary care physicians to squeeze in more patients per hour, and reward them for optimally managing their diseases and practicing evidence-based medicine. Make primary care more attractive food to medical students by forgiving students loans for those who choose primary care as a career and harmonizing the marked difference between specialist and primary care physician salaries.

We're at the point where primary care is needed more than ever. Within a few years, the first wave of 76 million Baby Boomers will become qualified for Medicare. Patients older than 85, who need chronic care most, will rise by 50% this decade.

Who will be there to treat  them？
