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.

Ultralight（超轻型的) airplanes are a recent development in aviation that provide what avia

Ultralight(超轻型的) airplanes are a recent development in aviation that provide what aviation enthusiasts have long been seeking: an inexpensive airplane that is easy to fly. The ultralight plane was born of the marriage of the hang glider and the go-kart(微型单座赛车) engine around 1974, when John Moody mounted a 12-horsepower go-kart engine on his Icarus Ⅱ hang glider.

Today’s ultralights are not just hang gliders with engines; they are" air recreation vehicles". Modem ultralight planes use snowmobile(雪地机动车)engines that let them cruise at about 50 miles per hour, climb at about 500 feet per minute, and carry combined payloads of pilot and fuel up to about 200 pounds, which is about equal to an ultralight plane’s weight when empty. More than ten thousand ultralight planes were sold last year at prices ranging from $ 2,800 to $ 7,000. But the main reason for the increasing popularity of these aircraft is not that they are inexpensive, but that they are fun to fly.

The modern ultralight plane would look very familiar to the earliest pioneers of aviation. Otto Lilienthal made more than 2000 flights in Germany in the 1890’s in what were actually hang gliders. Octave Chanute designed and built many early hang gliders. Augustus Herring, Chanute’s assistam, used these gliders as models for a glider that he built for him self. On this glider, Herring installed a compressed-air motor and flew 267 feet in 1898. The Wright brothers' Flyer was the grandfather of today’s ultralight plane. The pilot sat right out in the open, just as in modem ultralights, and used con trois that were much the same as those used in today's machines.

Though most ultralight planes are used for pleasure flying, some are also used for crop dusting, aerial photography, and even military observation service. The likelihood is that further uses will be found for ultralight planes, but their greatest use will continue to be as air recreational vehicles.

The author seems to feel that ultralight airplanes are ______.

A．a toy for the rich

B．nothing but hang gliders

C．a new development that meets the needs of aviation enthusiasts

D．the most important development in aviation since the Wright brothers' Flyer

Inertial guidance is the name given to those types of systems which guide and keep track o

f the location of vehicles which are free to move in three dimensions. Vehicles which move only on a plane surface, such as ships or automobiles, require only an accurate compass, sextant, and clock to keep track of their present position. When a vehicle can travel up or down as well as north or east, it is much more difficult to fix its position. An inertial platform. is used in inertial guidance to measure vehicle altitude and acceleration which are then integrated to provide position and velocity. The inertial platform. consists of three gyroscopes and three accelerometers mounted in the inner gimbal of the four gimbal platform. The purpose of the inertial platform. is to allow the vehicle to move in any direction about the inner gimbal containing the gyros and accelerometers, without disturbing or turning them from their original orientation. Thus the gyros and accelerometers do not mm when the vehicle turns so they sense altitude and acceleration with respect to their original inertial reference frame. If the acceleration is always known with respect to this original inertial reference frame, it can be integrated to provide velocity and then integrated again to provide distance. Thus the distance and velocity of the vehicle with respect to its starting point are known.

Inertial guidance systems are used today in airplanes, submarines, and spacecraft. They display for the pilot his pitch, roll and yaw angles, his heading, his speed, and his latitude and longitude. These are very important items to have readily available, whether one is in a high speed vehicle with very low visibility due to poor weather, or in a spacecraft traveling in lunar orbit. The main features of inertial systems are that they are automatic and do not require any external information. Thus, the pilot does not have to feed in any information except the original position and altitude. Inertial systems serve a need on fast moving vehicles moving in a three dimensional plane, where position information is required by the pilot almost constantly.

It can be interred from the article that an inertial guidance system is similar to

A．a gyroscope.

B．a high speed vehicle.

C．a navigator.

D．a submarine.

听力原文：W: Today we have with us Dr Michael White, a space scientist, to tell us about a

new space plane that British scientists are working on. Firstly, Dr White, could you tell us what the space plane looks like？

M: Well, it looks just like an ordinary plane, really. It’s about the same size as a plane, and it can carry about 50 passengers.

W: But it doesn’t act like an ordinary plane, does it？

M: No, it’s much faster. For example, you could fly from London to Beijing in only 30 minutes.

W: My goodness! And how does it work？

M: Well, shortly after taking off, the plane leaves the earth’s atmosphere and goes into orbit around the earth until it returns to the ground.

W: So it’s really a kind of space rocket.

M: Not really, no, for two reasons. First, a space rocket can only be used once, but this space plane can be used for many times. Second, while the plane is traveling through the atmosphere, the pilot can fly it just like an ordinary plane.

W: It sounds very exciting.

材料：

MV Oakland completed loading in the port of Buckie in the early evening．The master，an experienced shiphandler，personally manoeuvred Oakland out of harbour．The chief officer joined the master on the bridge shortly before clearing the northern breakwater．Once clear of the breakwater the course to steer to make for the open sea was 295° leaving the shoreline and some rocks to port and the West Muck rocks to starboard. From his previous experience and earlier advice from the pilot who had brought the vessel into port，the master knew that this course cleared the south rocks by about 750m and West Muck rocks by about 450m．

A light beacon which marked the West Muck rocks and lay some two and three quarter cables to the north-west of the northern breakwater was not lit．Neither the master，nor the mate was aware of this．Once clear of the harbour the master became distracted by the working light of a vessel at anchor about 0.5 mile distant on his starboard and thought he was to port of his intended track．He altered course to starboard to regain it and，once he thought he was back on track，altered back to port．Moments later Oakland grounded on the West Muck rocks．

The following morning Oakland was refloated on the rising ride with the aid of a tug．

问题：

It is inferred that MV Oakland was brought alongside at Buckie by _____．

A.a pilot

B.the master

C.the chief mate

D.an experienced shiphandler

Prior to his first altering course to starboard，the master thought he deviated to port of his intended track steaming too far away from ______．A.the northern breakwater

B.the shoreline

C.West Muck rocks

D.the south rocks

The master most possibly mistook the working light of a vessel at anchor as the light marking ______．A.the shoreline

B.the south rocks

C.the northern breakwater

D.West Muck rocks

Of the following，______ is not the lesson of this accident．A.The master of a vessel making an occasional visit to a port is less likely to have accumulated sufficient handling experience

B.An experienced master should not be too confident of his ability to undertake what appears to be a straightforward act of pilotage

C.When conducting your own pilotage，it is always necessary to check with the harbour authorities to ensure you know of any local notices to mariners

D.Steering is one of the oldest skills of seamen，but it is not just as important today as it ever was

听力原文： O'Hare Airport and Hartsfield-Jackson International Airport in Atlanta, Georgia

each claims to be the world's busiest airport. O'Hare may be the world's busiest airport. Or it may be only the second busiest. But everything about it is big.

The Federal Aviation Administration says more than nine hundred thirty thousand flights traveled through O'Hare last year. During that time, more than sixty-nine million passengers passed through O'Hare.

Most of these people were waiting for connecting flights. As they waited, they could shop at many airport stores. They could eat at airport cafes. They could exercise at a health club or do office work in a business-support center. They could take their children to a flight museum or visit the airport's religious center.

The huge O'Hare Airport of today is very different from its beginning. It started as a military air base and factory in the nineteen forties. The center produced planes for World War Ⅱ. Later, the airport was named for Navy pilot Edward O'Hare. He was killed in an action during the war after being honored with medals for bravery.

Big as O'Hare airport is today, however, it is not big enough. Too many airplanes crowd the runways where they take off and land. Delays and cancellations interfere with air traffic across the country. Officials say sixty-five percent of the flights at O'Hare were delayed during the first seven months of this year. This was the worst record among the nation's major airports.

To improve the situation, the governor of Illinois signed the O'Hare Modernization Act last year. The Act calls for building another runway. Existing runways would be moved and extended. More buildings are planned. The project will cost more than six-and-one-half-thousand-million dollars. When all that is completed in the next eight years, busy O'Hare Airport can get even busier.

Last year, how many flights traveled through O' Hare according to the Federal Aviation Administration？

A．930,000.

B．970,000.

C．913,000.

D．914,000.
