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.

"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

填句补文

Biological Clock

When the sun rises on a warm and sunny day, you can see some flowers open up. When they close late in the afternoon, other flowers open.

Biological rhythms(生物节律), like the opening and closing of flowers, happen all over nature. But not all of them are daily rhythms. Some, like the beating of our heart, happen every second. （1）Scientists use the term biological clock to describe the timing that controls biological rhythms. （2） In some animals it is probably controlled by the brain. In plants and other living things that have no brain, it must be something else.

The migration of animals happens when a signal is sent out. For example, when days become shorter, birds leave the northern parts of the world and fly south where it is warm. （3）Humans also have biological clocks that control their daily rhythms. When people travel by plane from one continent to another, they often cross many time zones. Their internal clocks don’t seem to work correctly. We call this jet lag(时差). （4）People who work night shifts also have problems with their biological clocks. They may not be as active as people who work during the daytime.

Biological clocks control many rhythms of life. （5） Doctors are looking for new ways to make travelling more comfortable and medical treatment more effective.

A. But where can you find it？

B. This makes them feel tired.

C. In the summer they fly back to have babies.

D. We are learning more and more about them.

E. Biological clocks can be adjusted.

F. Other rhythms are based on months, seasons or years.
