A cheap drug that can stop bleeding in people recently injured in an accident could potentially save the lives of tens of thousands worldwide, a new study says.

Researchers studied the effects of tranexamic acid （凝血酸）, or TXA, in more than 10,000 injured people in 40 countries who received the drug within 8 hours of being injured. The study was published in the medical journal Lancet. Doctors found that patients who got TXA had a 15percent lower chance of dying from hemorrhage than those who didn’t get it . They also had a 10 percent lower chance of dying from any other cause, including organ failure and a head injury. The study was paid for by the British government.

The drug is commonly used in wealthy countries during elective surgeries(外科手术) to stop bleeding , but isn’t used for accident victims. TXA is off-patent and made by many companies. It costs about $4.5 per gram, and a typical dose is two grams. It is usually given via an injection（注射） and would be relatively easy to introduce, even in poor countries, experts said.

Previous tests of the drug regarded its use in elective surgeries, such as heart operations, but this was the first study to test the drug on accident victims. Doctors were worried it might increase side effects such as blood clots （凝块）in the heart and lungs, strokes, or heart attacks. There was no evidence of that in the Lancet study, though the authors said it was possible they might have missed some of these incidents.

For people between 5 and 45, accidents are the second leading cause of death worldwide after AIDS, and about 600,000 injured patients bleed to death every year. Experts estimated that if TXA were readily available, between 70,000 and 100,000 lives a year could be saved. Though the drug wasn’t tested on children , experts said it would almost certainly work with them as well.

1.The underlined word” hemorrhage” in Paragraph 2 probably means ________

2.What can we learn about TXA from the passage?

3.Doctors were worried about using TXA because ________

4. What do we know from the last paragraph?

National parks in the UK are a wonder to see, run by the National Trust, a non-profit charity which maintains Great Britain's historical and natural landscapes. Britain's park Authority has made planning restrictions to protect these wilderness areas in housing and commercial activities.

Mainland England and Wales have the largest number of protected parks. The first established area was the l,438 kilometer Peak District. The first national park lies in northern and central England. The Peak District with vast beauty is thought to be the world's most visited national park after Japan's Mount Fuji.

In the northwest area of Wales lies Snowdonia National Park. This attractive, mysterious ancient landscape is home to steep mountains. Walking trails to Mount Snowdon is only one of several exciting activities for hikers.

National parks in the UK can also boast of having Britain's largest protected wetland "The Broad", just outside the village of Homing. An ideal spot for families, this 200-mile area combines waterways with an interesting intersection(交叉) of windmills, castles and an ancient Normal church.

Spreading across 885 miles of truly impressive rocky land is Lake District National Park. England's largest park attraction is spread between Edinburgh to the north and Manchester to the south. Although the land itself seems wild, almost 40,000 people live within the park. Within this district's vast borders we can find over 6,000 archaeological(考古的) sites and monuments dating back to prehistory.

The United Kingdom has taken great care to preserve its wilderness areas for the future generations, and all the parks are adventures waiting to De found which can be enjoyed by both natives and visitors.
