第1题 (20) 分
We don’t have beds in the space shuttle, but we do have sleeping bags. During the day, when we

are working, we leave the bags tied to the wall, out of the way. At bedtime we untie them and take

them wherever we’ve chosen to sleep.

On most space shuttle flights everyone sleeps at the same time. No one has to stay awake to watch

over the spaceplane; the shuttle’s computers and the engineers at Mission Control do that. If

anything goes wrong, the computers ring an alarm and the engineers call us on the radio.

On the space shuttle, sleep-time doesn’t mean nighttime. During each ninety-minute orbit the sun

“rises ” and shines through our windows for about fifty minutes; then it “ sets ” as our path

takes us around the dark side of the earth. To keep the sun out of our eyes, we wear black sleep

masks.

It is surprisingly easy to get comfortable and fall asleep in space. Every astronaut sleeps

differently. Some sleep upside down, some right side up. When it’s time to sleep, I take my bag,

my sleep mask, and my tape player with earphones and float up to the flight deck. Then I crawl

into the bag, and float in a sitting position just above a seat, right next to a window. Before I

pull the mask down over my eyes, I relax for a while, listening to music and watching the Earth go

by beneath me.

第4题 (20) 分
In many stories on TV and in science-fiction books, men travel to faraway stars. They have quick,

easy journeys. But so far, men have been able to reach only the earth’s own moon.

Suppose a man wanted to reach a distant star. Even if he traveled his whole life, he would have to

move faster than the speed of the light. Nothing can move that fast except light itself.

Strange things happen to an object when it moves rapidly. The object weighs more. An object moving

at 86 percent of the speed of light is twice as heavy as it is at rest. A stick appears shorter. A

clock runs more slowly. A man would not age so fast as he would on the earth.

Light travels more than 186,000 miles a second, or about 11 million miles a minute. In one year,

light travels six trillion miles. That great distance is called a light-year. It is used to

measure distance in space.

The star closest to our sun is Alpha Centauri. It is more than four light-years away. If one

traveled at the speed of light, he could make a round trip to Alpha Centauri in nine years. But,

even at that speed, he could not reach Alcaid (北斗星) in the handle of the Big Dipper. A one-way

journey to Alcaid would take almost 200 years.

1.阅读理解 (2) 分

A、the earth we live on

2.阅读理解 (2) 分

A one-way journey to Alcaid would take _________ .

A、about nine years
B、less than four years
C、almost 200 years
D、less than 100 years


3.阅读理解 (2) 分

Why do we measure the distance in light-years instead of miles?

A、Units of light-years sound better.
B、Using light- years reduced the number of figures used.
C、We used to measure distance in light-years long ago.
D、We do not make mistakes when we use light-years.


4.阅读理解 (2) 分

If a stone moved at the speed of light, it _________ .

A、would weigh twice more than it is motionless
B、would weigh as much as it is on earth

第5题 (20) 分
Today a pilot is totally dependent on what the air traffic controller on the ground tells him. He

can not see enough to be safe. Flightwatc

h is an instrument intended to help him.

On a screen in front of the pilot, there will be a map of the airspace around the plane. The pilot

’s own flight level or height and his own plane at the centre of the screen will show up. On the

map any other planes in the airspace will appear as blobs (点状)of light with “tails” showing

the direction of their flight. The flightwatch map is unusual, for the other planes are not shown

at their true ranges (范围), but at their distance away in flying time. That gets over the

problem of fast planes being too far away to be seen but likely to make contact in seconds and

slow planes that are close enough to be seen but so slow that there’s no chance of contact for,

say, ten minutes.

The pilot will be able to see on the screen whether another plane’s course conflicts with his

own. 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 avoiding action if

necessary. The screen will show him whether his action puts him in danger from yet another

aircraft.

Technically, the system will be quite complex. Computers will be necessary on the ground and in

each aircraft to enable flightwatch to collect data about the planes’ courses and to calculate

the distances between planes. But such small computers are now quite cheap, simple and reliable.
