Today a pilot is totally dependent on what the air traffic controller on the ground tells

him. He can't see enough to be safe. Flight watch is an instrument intended to help him.

On a screen in front of the pilot, there will be a map of the【21】around the plane. The pilot's own【22】level or height and his own plane at the center of the【23】will show up. On the map any other planes in the airspace will【24】as spots of light with "tails" showing the direction of their light. The flight watch map is【25】for the other planes are not shown at their true【26】, but at their distances away in flying time. This【27】the problem of fast planes being too far away to be seen【28】likely to make contact in seconds and【29】planes that are close enough to be seen but so slow that there's no chance of【30】for, say, ten minutes.

The pilot will be able to see on the screen whether another plane's course conflicts with【31】. The screen will show him the flight number of the other plane, so he can contact air traffic control and ask them about the other plane’s course. Then he can take【32】action if necessary. The screen will show him whether his action puts him【33】from yet another aircraft.

Technically, the【34】will be quite complex. Computers will be necessary on the ground and【35】each aircraft to enable Flight watch to collect data about the plane courses and to calculate the distances between planes. But such small computers are now quite cheap, simple and reliable.

A．latitude

Excitement, fatigue, and anxiety can all be detected from someone's blinks, according to p

sychologist John Stern (21) Washington University in St. Louis. Stern specialized in the study on these tiny twitches, using them as sensitive (22) of how the brain works. "I use blinks as a psychological measure to make (23) about thinking because I have very little (24) in what you tell me about what you are thinking." He says. "If I ask you the question, 'what does the phrase a rolling stone gathers no moss mean？' you can't tell me (25) you've started looking for the answer. But I can, by watching your eyes."

Blinks also tell Stern when you have understood his question--often long before he's finished asking it--and when you've found an answer or part of (26) . "We blink at times (27) are psychologically important." He says. "You have listened to a question, you understand it, (28) you can take time out for a blink. Blinks are (29) marks. Their timing is tied to what is going on in your (30) ."

Stern has found that (31) suppress blinks when they are absorbing or anticipating (32) but not when they're reciting it. People blink later, for example, (33) they have to memorize six numbers instead of two. "You don't blink," he says, "until you have (34) the information to some short-term memory store." And if subjects are cued (35) the set of numbers is coming, say, five seconds, they'll curb their blinks until the task is (36) . Similarly, the more important the information that people are taking in, the more likely they are to put their blinks on hold for (37) Pilots blink less when they're (38) for flying a plane than when they (39) their eyes from the road to the rearview mirror. But if they see the flashing lights of a state trooper behind them, their (40) will move fast to the speed-meter and back to the mirror.

"If you had to identify, in one word, the reason the human race has not achieved, and neve

r will achieve, its full potential, that word would be meetings." Thus spoke humorist Dave Barry, and many of us would agree. But it doesnt have to be this way. Some tips for having a good one: Start and end strongly. Running a productive meeting isnt rocket science. As Denver-based consultant Teri Schwartz notes, much of it boils down to opening and conducting every meeting with a purpose and closing it with a plan for "going forward." Problems arise when people forget this. "Its like flying a plane," says Schwartz. "Most crashes happen at takeoff and landing." Pick a leader. Four years ago, Clevelands KeyCorp Bank adopted a new principle: Always assign someone to lead. "The worst thing you can do is go into a meeting with no one in charge," says the banks senior EVP and chief risk officer, Charles Hyle. "It turns into a shouting match." Think small. Be realistic about what you can accomplish. "You cant solve world hunger in an hour," Schwartz says. By the same token, keep the number of attendees manageable to stimulate discussion. "When you have too many people in the room," says Hyle, "everyone clams up as if their mouths were sealed." Direct, dont dominate. "People hate it when they cant get their work done because they have to go to somebody elses meeting," says Columbia Business School professor Michael Feiner. So encourage others to speak up and get involved, especially junior staffers. "They need to believe its not his meeting or her meeting, but our meeting," Feiner says. Lay down the rules of engagement. Everyone should understand who will take notes and how decisions will be made. Remember that consensus is typically a bad thing. "It means there isnt enough dialogue or debate," says Feiner, "and thats the lifeblood of any innovative organization." Jon Petz, the author of Boring Meetings Suck, suggests assigning follow-up tasks during the final five to ten minutes, then repeating them later in a group e-mail so that theres no confusion.

In Dave Barrys opinions, meetings______.

A．have been blocking human progress

B．may fade away from the human world

C．are an important part of the human race

D．are meant to solve problems for humans
