Vitamin D3 Improve Heart Function
A daily dose of vitamin D3 improves heart function in people with heart failure, a five-year University of Leeds research project has found.
Dr. Klaus Witte, from the School of Medicine and Consultant Cardiologist at Leeds Teaching Hospitals NHS Trust, led the study. He said: “This is a significant breakthrough for patients. It is the first evidence that vitamin D3 can improve heart function of people with heart muscle weakness –known as heart failure.” 1.
Vitamin D3 can be boosted by exposure to sunlight, but heart failure patients are often deficient in it even during the summer because older people make less vitamin D3 in response to sunlight than younger people. Vitamin D3 production in the skin is also reduced by sunscreen.
The study, which was funded by the Medical Research Council, involved more than 160 patients from Leeds who were already being treated for their heart failure using proven treatments including beta — blockers, ACE-inhibitors and pacemakers. 2. Those patients who took vitamin D3 experienced an improvement in heart function which was not seen in those who took a placebo.
3. Heart specialists measure heart function by taking an ultrasound scan of the heart and measuring how much blood pumps from the heart with each heartbeat, known as ejection fraction. The ejection fraction of a healthy person is usually between 60% and 70%. In heart failure patients, the ejection fraction is often significantly impaired — in the patients enrolled into the study the average ejection fraction was 26%.
In the 80 patients who took Vitamin D3, the heart’s pumping function improved from 26% to 34%. 4. This means that for some heart disease patients, taking vitamin D3 regularly may lessen the need for them to be fitted with an implantable cardioverter defibrillator (ICD), a device which detects dangerous irregular heart rhythms and can shock the heart to restore a normal rhythm.
A. Heart failure can by all means be cured by Vitamin D3.
B. Changes in heart function were measured by ultrasound.
C. In the others, who took placebo, there was no change in cardiac function.
D. Participants were asked to take vitamin D3 or a placebo tablet for one year.
E. Sunscreen will prevent people from absorbing more Vitamin D3 to a great extent.
F. The finding could make a significant difference to the care of heart failure patients.
Though the spread of good reproduction (复制品) of works of art can be culturally valuable, museums continue to promote the special status of original work and highlight the authenticity (真实) of its exhibits. Unfortunately, this seems to place severe limitations on the kind of experience offered to visitors.
One limitation is related to the way the museum presents its exhibits. Art museums are often called “treasure houses”. We are reminded of this even before we view a collection by the presence of security guards who keep us away from the exhibits. In addition, a major collection like that of London’s National Gallery is housed in numerous rooms, where a single piece of work is likely to be worth more than all the average visitor possesses. In a society that judges the personal status of the individual so much by their material worth, it is therefore difficult not to be impressed by one’s own relative “worthlessness” in such an environment.
Furthermore, consideration of the “value” of the original work in its treasure house setting impresses upon the viewer that since these works were originally produced, they have been assigned a huge value in terms of money by some person or institution more powerful than themselves. Evidently, nothing the viewer thinks about the work is going to alter that value, and so today’s viewer is discouraged from trying to extend that spontaneous, immediate, self-reliant kind of interpretation which would originally have met the work.
The visitor may then be struck by the strangeness of seeing such a variety of paintings, drawings and sculptures brought together in an environment for which they were not originally created. This “displacement effect” is further heightened by the huge volume of exhibits. In the case of a major collection, there are probably more works on display than we could realistically view in weeks or even months.
This is particularly distressing because time seems to be a vital factor in the appreciation of all art forms. A fundamental difference between paintings and other art forms is that there is no prescribed time over which a painting is viewed. Operas, novels and poems are read in a prescribed time sequence, whereas a picture has no clear place at which to start viewing, or at which to finish. Thus art works themselves encourage us to view them superficially, without appreciating the richness of detail and labor that is involved.
Consequently, the dominant critical approach becomes that of the art historian, a specialized academic approach devoted to “discovering the meaning” of art within the cultural context of its time. This is in harmony with the museum’s function, since the approach is dedicated to seeking out and conserving “authentic”, “original” readings of the exhibits.
1.The writer mentions London’s National Gallery to illustrate ______.
A.the undesirable cost to a nation of maintaining a huge collection of art
B.the conflict that may arise in society between financial and artistic values
C.the negative effect a museum can have on visitors’ opinion of themselves

A.involve direct contact with an audience
B.require a specific location for performance
C.need the involvement of other professionals
D.call for a specific beginning or ending
4.Which of the following might be the best title of the passage?
A.Original work: killer of artistic appreciation

McCoy was looking for a safe place to do drugs when something clearly out of place caught his eye: a luxurious brown leather handbag.
McCoy, 36, could relate all too well. One of his few possessions, the sleeping bag he used in an abandoned house, had recently been stolen. Remembering how angered he’d been by his own loss, he resolved to return the purse to its owner.
He began right away, starting with the address on the bill found in the handbag. After traveling much of the day and finally approaching the address on the bill, he was stopped by a woman, who asked whether she could buy the purse. McCoy refused, saying he was searching for its owner. “But I am the owner,” the woman said. “That’s my purse.”
A month earlier, Kaitlyn Smith, 29, a sales representative for a medical device company, had woken up to find her apartment broken into and her purse stolen. Now she came across a tall, messy-looking man holding it tightly. She could instantly tell he wasn’t in good shape.
At Smith’s urging, McCoy told her his story. He’d been in charge of a landscaping business until 2012, when a car accident left him addicted to drugs.
Smith, amazed this stranger had gone to such great lengths to return her bag, asked whether there was anything she could do to help. “I’m a drug addict,” McCoy warned. “I don’t want to intrude on your life; I’m probably gonna let you down.”
Unafraid, Smith gave him her phone number, saying, “If you want to go to rehab (戒毒所), call me.” She then drove him back to his neighborhood and left, thinking that would be the end of it. Two days later, she got a call.
Smith realized that McCoy was serious about getting better, so she dug into her savings account and bought McCoy a plane ticket to Florida. While there, he would call her to let her know how he was doing. “We were getting to know each other,” Smith says. “His scared, desperate voice turned into a healthy, lively one.” After 28 days at a rehab program at Johns Hopkins Hospital, McCoy is drug-free. He lives at a residential recovery center in Baltimore, and a GoFundMe page set up by Smith has covered his rent, groceries, and incidentals. His life is back on track, all because one crime victim could understand another’s loss.
1.What drove McCoy to look for the owner of the handbag?
A.The urge to find a business partner. B.The resolution to recover his sleeping bag.
C.His own unfortunate experience. D.His anger over the poor living condition.
2.What was McCoy’s initial reaction towards Smith’s intention to help?

Native people in the desert regions of the American Southwest have followed ______ strategies, encouraging tourists to visit their towns and reservations to ______ high-quality handicrafts and artwork. Some have established highly profitable stoneware businesses, while the Navajo and Hopi groups have been similarly ______ with jewelry.

Mako sharks get new protections
At the global wildlife trade meeting in Geneva, countries have decided to protect the endangered mako shark from trade. GENEVA made the proposal 1. more protections should be taken for both shortfin and longfin mako sharks and was adopted today after a 102-40 vote at the global wildlife trade summit. The vote still needs to be finalized at the full meeting at the end, when all appendix (附录) change proposals passed in committee are officially adopted.
The proposal, debated at this year’s CITES Conference, lists mako sharks under Appendix II, meaning that they can’t be traded 2. it can be shown that fishing wouldn’t threaten their chances for survival. Conservationists say this was the world’s last chance to prevent mako shark populations from collapsing.
3. (list) mako sharks on CITES Appendix II is great news for shark conservation. More than 50 of the 183 CITES members signed on as supporters of the proposal brought forth by Mexico. Nonetheless, conservationists feared that opposition from a few countries with fairly large mako fishing industries—primarily the United States, Canada, and Japan—4. tip the scale. Japan opposed the measure during the debates, and the United States announced afterward it 5. (vote) no.
In the past, the U.S. and others have supported listing other shark species under CITES, but not so in this case, 6. commercial interests. For a lot of these countries, they were happy to list shark species when it was ones they weren’t so heavily involved in fishing. Suddenly, when they’re being asked to be responsible, rather than asking other people to be responsible, they’re 7. (little) keen to take it on board.
The International Union for the Conservation of Nature, which determines the conservation status of species claims that both species of mako sharks to be endangered, saying an 8. (estimate) 50 to 79 percent population decline over three generations, or about 75 years. They 9. (target) for their fins (鳍), used in shark fin soup—a dish in Asian countries, that’s often served at weddings as a sign of respect for guests. Their meat is more edible compared to 10. of other sharks, which is often acidic and is usually sold as a byproduct of the fin trade for “pennies on the dollar”.
