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.

A．control all the planes flying near the airport

Everyone knows, for example, that air-traffic controllers have more than their share of white-knuckle day. But stressful jobs are not equally stressful to all people. Some air-traffic controllers thrive on the flying circus. Their secret, says Suzane Ouellette, a psychologist at the City University of New York, is "hardiness", a balance of feeling committed, challenged and in control in the workplace.
Then again, some professions are inarguably tough to take. Doctors, lawyers and police officers routinely top suicide lists. And some jobs are plain dangerous: miners have the highest job-fatality rate in the country. Less extreme but much more widespread are the psychological hazards that result from 10 years of corporate downsizing and having to keep up with the speed and volume of computers. Dr. Rupert. Burtan, a specialist in occupational medicine, says," Many workers have too much dumped on their desks and nor enough time in which to get it all done." That complaint is often made by secretaries, who also make most stressed-out lists.
Jobs that attract idealistic types can sour（使人不愉快的） when the work seems to make little meaningful difference. Besides police officers and lawyers, inner-city teachers and journalists often fall into this category. Doctors, interns and nurses can, too, when the waves of the sick seem endless.
Why the recent wave exhausts basketball coaches? Sports give them tremendous responsibilities but, ultimately, little control. Coaches can only coach; they can't actually run the plays. But if the team loses, they still get fired. Similarly, waiters and waitresses get stiffed on tips if the cook screws up.
But experts say the toughest occupation may still be that of working mom. Many women who are bringing home the bacon are still expected to fry and serve it, too. '' There really are relatively few couples where child care and domestic work are truly shared," says Harriet Lerner, a psychologist at the Menninger Clinic. Even unemployed husbands do no more than 36percent of the housework. Now that's a study in high stress and high shame.
1．The example of air-traffic controllers is given in Para. 1 to show that .
A．it’s not easy to decide which jobs are stressful
B．nobody wants to be an air-traffic controller
C．they can easily succeed in their career
D．their job is the most dangerous one
2．The underlined word “it” in Para. 2 refers to .
A．the working time B．the speed of computers
C．the amount of work D．the size of computers
3．What makes working mothers have the toughest occupation?
A．The housework only. B．The unhappy family life.
C．The full-time job. D．Their double roles.
4．It can be inferred from the passage that .
A．people often lose interest in their jobs
B．people tend to choose wrong professions
C．it is easy to find an ideal job in modern times
D．the ideal jobs can turn stressful as well
