The Monday edition of USA Today said sixty people have died in 84 crashes since 2000. This is more than double the number of crashes during the previous five years. Its study found that more than 10 percent of the U. S. air ambulance helicopters (救护直升机) crashed during that time and about two-thirds of the fatal crashes occurred in poor visibility.After reviewing hundreds of pages of documents and interviewing dozens of pilots, federal officials and executives with the companies that operate the flights, USA Today concluded that air ambulance companies have failed to apply safety requirements that might have saved lives. It also found that helicopters were used "excessively" for patients who weren’t severely injured.But the newspaper also noted that there are studies which show that thousands of lives are saved each year by speedy flights to hospitals. It pointed out, as well, that pilots operate in challenging situations, such as having to land on hospital roofs and being sent on life-and-death tasks to rural accident scenes despite darkness or bad weather. "I don’t know anybody in this industry who isn’t devoted to safety and devoted to what we do," Ron Fergie, president 6f the National EMS Pilots Association, told USA Today. What conclusion can you make from USA Today concerning the increasing deaths since 2000()

A. The pilots of ambulance helicopters should be blamed.
B. The air ambulance companies should be blamed.
C. Helicopters are not frequently used to save people’s lives
D. There are too many tasks for ambulance helicopters.

Although our educational system and our society generally place a high value on competition, some problems can be better solved through cooperation and some forms of learning are strengthened through cooperation. Both competition and cooperation have a place in society and can serve a useful purpose. Consequently, it is necessary to be able to engage in both processes depending on the circumstances and one’s goals.In the academic environment grades are often conceived as the major criterion (标准) for the assessment of learning. We tend to assume that the higher one’s grade average, the more one has learned, thus creating greater competition for grades. This competition can be particularly intense in fields where the financial rewards are great and opportunity is limited: law, engineering, medicine, and business.However, the measure of one’s learning is not limited to grades. It is possible to learn a great deal about a subject and receive a low grade or even no grade in the evaluation. No grade can be used to define what we learn about ourselves from sharing what we know with others. And no one can give us a grade for how we feel about ourselves and about our relationships with others. What is the main idea of the second paragraph()

A. The higher one’s grade average, the more one has learned.
B. Our education system encourages competition for higher grades.
C. Grades are regarded as the criterion to evaluate students’ performances.
D. Competition for financial rewards is more intense in some fields than in others.

Visitors exploring one of Britain’s many historic buildings might expect to see beautiful objects and learn more about history. What they won’t expect is to meet one of the former residents, and to be able to talk to them about their life and times. But, don’t worry. Although many old buildings are said to be frequently visited by ghosts (幽灵), these people are not ghosts at all.All across Britain historic sites will be brought to life by real people. They will be dressed in period costumes (clothes worn in an earlier time in history) and will recreate life as it was once lived at different times during Britain’s history. Activities like these are called "living history", and have become increasingly popular in recent years.An organization named English Heritage, which maintains historic buildings and sites across England, will organize over 500 living history events, ranging from reenactment (再次展现) of battles to traditional story-telling for children.The people who dress up in costumes and take part in these events come from all kinds of backgrounds. Some are trained actors, while others do it as a hobby. What they all have in common, however, is that they do not simply "act". Instead, they learn about every aspect of the period they are bringing to life — everything from the way people behaved to the way they spoke. The people who take part in a "living history" event must()

A. play roles like actors
B. have a common interest
C. behave and speak the way the local residents do
D. know everything about the period brought to life
