C
Today, air travel is far safer than driving a car on a busy motorway. But still there is a danger that grows every year. Airliners get larger and larger. Some airplanes can carry over 300 passengers. And the air itself becomes more and more crowded. If one large airliner struck into another in mid-air, 600 lives could be lost.
From the moment an airliner takes off to the moment it lands, every movement is watched on radar screens. Air traffic controllers tell the pilot exactly when to turn, when to climb, and when to come down. The air traffic controllers around a busy airport like London-Heathrow may deal with 2,500 planes a day. Not all of them actually land at the airport. Any plane that flies near the airport comes under the orders of the controllers there. Even a small mistake on their part could cause a terrible accident.
Recently such a disaster almost happened. Two large jets were flying towards the airport. One was carrying 69 passengers from Toronto, the other 176 passengers from Chicago. An air traffic controller noticed on his radar screen that the two planes were too close to each other. He ordered one to turn to the right and to climb. But he made a mistake. He ordered the wrong plane to do this. So, instead of turning away from the second plane, the first plane turned towards it. Fifteen seconds later it flew directly in front of the second plane. They avoided each other by the smallest part of a second. The distance between them was less than that of a large swimming pool. This is an example of the danger that grows every year.

查看习题详情和答案>>Car crashes are the top killer of American teenagers．Most of the crashes result from distracted driving not paying attention to the road．
Ryan Didone was a fifteen-year-old passenger in a car that hit a tree．He was one of the nation's more than thirty thousand victims of traffic crashes in 2008．Nearly four thousand deaths, about twelve percent, involved drivers aged fifteen to twenty．Ryan's father, Thomas Didone, is a police captain in Montgomery County, Maryland．He said, "It was an inexperienced," immature driver who felt that he was invincible(不可战胜的), driving at night with a carload of kids．He was distracted, he was going too fast, and it ended up causing one death and some upsetting experiences and tragedy for the rest of the community."
Jim Jennings from the Allstate Insurance Company said "The number one cause of distracted-driving accidents is the mobile phone．Talking on the phone or reaching for it is like drinking four beers and driving．If you're texting while driving, you are twenty-three times more likely to get into an accident than somebody who isn't．
Reaching for a cell phone when it's going off, you're nine times more likely to get into an accident than normally driving," The insurance industry recently held a safety event near Washington for teen drivers．
At first, nineteen-year-old Kevin．Schumann easily avoided large, inflatable dolls thrown in front of the car to represent children．He also avoided orange cones representing the edge of the road．Then, as part of the test,he started texting. He hit several cones and at least one doll．
Debbie Pickford from the Allstate Insurance Company said, "Teens are especially at risk from distracted driving—and not just because they lack experience on the roads．What we know from research on teen brain development, is that teens don't really have fully developed brains until they are twenty-five years old. You put those two things together and you get a much, much higher risk.
71．We can learn from the second paragraph that _ _．
A．drivers who resulted in nearly 4,000 deaths are teenagers
B．over 30,000 victims have died from traffic crashes so far
C．it was at night that Ryan Didone died from a car accident
D．Ryan Didone's death was due to the other 's careless driving
72．According to the passage, __ is the most likely to lead to a traffic accident while you are driving．
A．reaching for a cell phone． B．texting on the mobile phone
C．talking on the mobile phone D．bringing along a cell phone
73．A safety event held by insurance industry was meant to _ _.
A．attract more teenagers to take part in it
B．make more teenagers practice avoiding large barriers
C．draw encough attention to teenagers' distracted driving
D．encourage more teenagers to pay for insurance protection
74．The passage is probably followed by a concluding paragraph about ___．
A．much higher risk B．measures to be taken
C．experience on the roads D．teen brain development
75. Of all the following, which is the best title for the passage?
A. Car Crashes —the Top Killer. B. Drunken Driving — Dangerous Enough！
C. Distracted Driving —Let's Avoid! D. Tips on Driving While Calling
