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(外科手術(shù)) 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 （凝塊）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.

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

 A. serious illness    B. heart disease     C. heavy bleeding   D. lack of drug

What can we learn about TXA from the passage?

 A. It can only be made in England     B. It was only used in operations before

 C. It is a patented drug              D. It is mainly used in poor countries

Doctors were worried about using TXA because ________

 A. a lot of patients died unexpectedly after using it

 B. it has no treatment effect on patients

 C. it can cause blood clots or stroke

 D. they hadn’t used it on accident victims before

What do we know from the last paragraph?

 A. It is a pity that TXA wasn’t widely used on injured patients before

 B. Tests have proved that TXA can be used on children

 C. People between 5 and 45 should be injected with TXA every year

 D. Accidents are the first leading cause of death worldwide.

 A friend of mine was sitting in the living room one day when his cat dragged in a little “gift” in its mouth—a dead animal of some sort. Taking a closer look, he was surprised to  36 it as the bunny(小兔子) that  37 Mary, the young daughter of the family next door. My friend felt  38 , believing his cat had killed Mary’s bunny.
My quick-thinking friend came up with a plan.  39  from the cat’s mouth the dead animal, which by now was a     40 mess, he put it in the kitchen sink. With a little warm water and some shampoo, he tried to  41 the dead bunny as best he could. Then he took a hair dryer and blowdried the bunny  42 it looked pretty good.
Finally, under the cover of darkness, he crept into the next-door garden and placed it  43 in the cage. He managed to make the bunny look very  44 there in his little box.
The next morning, my friend looked out of the window and noticed a crowd of people  45 around the rabbit hutch(籠). Everyone seemed to be talking and pointing. My friend  46 to go over and act like any normal  47 neighbor and find out what was going on.
When he got there, Mary’s mother said to my friend, “You won’t believe this! It’s a(n)   48 thing! Mary’s bunny  49 a few days ago, and we buried that little bunny right over there…”
Have you ever tried to cover up one wrongdoing with another? Covering up only makes matters  50 .
When we get caught doing something  51 , for example, we may  52 to cover it up with a lie. But just like Mary’s bunny, the result is  53 what we expected. We  54 looking foolish. We would have been better off admitting we were wrong and accepting the  55 . What do you think of it?

A few days ago, I was having a meeting in my company. After walking out, I 36  for my car keys in my pocket, only to discover they were not there. 37 , I gave myself a quick personal pat   38  my clothes, but they were not in 39  of my pockets. So, I went back to the meeting room and looked for them in every place _ 40_I had been. Suddenly it occurred to me that I must have left them in the car. Worried and frightened, I quickly 41  for the parking lot.（停車場(chǎng)）
My wife, Diane, has 42  me many times for leaving the keys in the ignition（點(diǎn)火處）. My theory is the ignition is the 43  place so that I won’t lose them. Her theory is that the car will be   44 . As I rushed out of my company, I came to a terrifying 45 . Her theory was right. The parking lot was 46 .
Without hesitation, I called the 47 . I gave them my location（位置）and  48  that I had left my keys in the car, and that it had been stolen. Then I made the most 49  call of all.
“Honey,” I said in a low voice. I always call her “honey” in times like these. “I 50  my keys in the car, and it has been stolen.”
There was a period of 51 . I thought the call had been dropped, but then I heard Diane’s  52 .
“Ken,” she shouted, “I dropped you off!”
Now it was my time to be silent. 53 , I said, “In that case, would you please come and  54  
your dear husband?”
Diane answered, “I will... just as soon as I can have this policeman  55 I didn’t steal your car.”
