The journey to the moon has been the first step towards future exploration（探险）space. The distance between the moon and the earth is very short indeed when compared the distances between earth and the other planets. Mars, the nearest planet to Earth is millions of miles away! Traveling to the planets will be man's next aim. Such travels will be more challenging(挑战) than the trip to the moon and certainly more adventurous( 冒险).
Recently, two American spaceships, Vikings 1 and 2, landed on Mars trying to discover whether that pla net has any life on it. So far the signs of life on Mars has neither confirmed（确认） nor ruled out. Russians have discovered that the surface of Venus(金星) is so hot that it is almost certain that there is no life there. Also the atmosphere of Venus is extremely dense(稠) and the pressure is nearly a hundred times greater than that of the earth's atmosphere.
Scientists believe man may find planets, which have the same conditions as those we have on earth, but man should realize the earth will be his only home for a long time and begin to love and care for it.
( )6. According to the passage, traveling to the planets will be_________
A. much easier and even more interesting B. far more exciting and dangerous
C. man's final aim D. man's first step
( )7. Which of the following is NOT true?
A. Mars is nearer to the earth than the moon.
B. The moon is much nearer to the earth than Mars.
C. Of all the planets, Mars is the nearest to the earth.
D. All the planets are much farther to the earth.
( )8. From the passage, we can guess__________
A. there is life on Mars
B. there is no lif e on Mars
C. the atmosphere of Mars is not so dense as that of Venus
D. Scientists will have little hope to find the answers
( )9. Man can live on under the con ditions of_____________
A. much too hot surface B. the same pressure as we get on the earth
C. normal atmosphere as we have on the earth D. both B and C
( )10. Scientists think we should take care of our earth because____________
A. no other planets are going to take the place of the earth
B. everything needed is provided by the earth
C. the only home of man will be the earth for a long time
D. the dream to find another home for man will come true
Like all the planets in our solar system, Earth and Mars go around the sun. But Earth is closer to the sun, and therefore revolves along its orbit(轨道) more quickly. Earth makes two trips around the sun in about the same amount of time that Mars takes to make one trip. So sometimes the two planets are on opposite sides of the sun, very far apart, and other times, Earth catches up with its neighbor and passes relatively close to it.
Since Mars and the sun appear on opposite sides of the sky, we say that Mars is in “opposition”. Mars oppositions happen about every 26 months. Every 15 or 17 years, opposition occurs within a few weeks of Mars’ perihelion(近日点).
An opposition can occur anywhere along Mars' orbit. When it happens while the red planet is closest to the sun (called “perihelic opposition”), Mars is particularly close to Earth. If Earth and Mars both had perfectly stable orbits, then each perihelic opposition would bring the two planets as close as they could be. So, with all these added factors, some bring us closer together than others. The 2003 opposition was the closest approach in almost 60,000 years!
Mars’ orbit is more elliptical(椭圆的) than Earth’s, so the difference between perihelion and aphelion(远日点) is greater. Over the past centuries, Mars’ orbit has been getting more and more elongated, carrying the planet even nearer to the sun at perihelion and even farther away at aphelion. So future perihelic oppositions will bring Earth and Mars even closer. Our 2003 record will stand until August 28, 2287!
( )11. Mars ______.
A. isn’t one of the planets in our solar system B. is farther from the sun than the earth
C. never meets Earth close D. and Earth have the same orbit around the sun
( )12. The time Mars takes to go around the sun is _________ that Earth needs
A. as long as B. not so long as
C. as about two times long as D. as about three times long as
( )13. Which of the following statement is not right?
A. When Mars is in “opposition”, Mars and the sun are opposite in the sky.
B. Mars oppositions happen about every 15 or 17 years.
C. An opposition can occur everywhere along Mars’ orbit.
D. Mars oppositions happen about every 26 months.
( )14. In the sentence “… Mars’ orbit has been getting more and more elongated…”，elongated means _______.
A. 伸长的 B. 拉长 C. 延长 D. (被拉得)细长的
( )15. From the passage, we can know the next perihelic opposition _______.
A. is the closest approach in almost 60,000 years
B. will bring Earth and Mars even farther
C. will happen on August 28, 2287
D. is in 2003

A Little Help from the Sun
Even though Mars doesn't always come close enough for astronomers（天文学家）to get a good look at it when Earth speeds past, scientists have an opportunity to launch a spacecraft to Mars every 26 months.
Unlike vehicles in science fiction movies, spaceships don't just take off in any direction. Escaping（避开）Earth's gravitational pull requires a lot of energy. Even then, without an extra push, a spacecraft would never reach the orbit of Mars.
To get a spacecraft to Mars, scientists time the launch so the spacecraft reaches Mars when the red planet is on the opposite side of the sun from Earth. This way, they take advantage of solar gravity, which causes a spacecraft to “fall” toward the sun, traveling in an arc around it. This moti on follows physical laws described by Isaac Newton and Johannes Kepler in the 17th century.
”What you want to do is launch the spacecraft so it goes around the sun to meet Mars, ” says Jah. “We give it the least amount of energy possible and let the sun's gravity do as much as it can for us. ”
As a result, like a warrior in a Roman chariot race, the spacecraft comes up on Mars from behind. But instead of sailing past, it slows down and lands.
1．Do scientists have an opportunity to launch a spacecraft to Mars every 26 months?
______________________________________________________________
2. If a spaceship wants to escape Earth’s gravit ational pull, what does it need?
______________________________________________________________
3．When can the spacecraft get to Mars by the scientists’ opinion?

4、Who described the physical laws that were mentioned in the passage in the 17th century?

5．What’s the Chinese meaning of the sentence “What you want to do is launch the spacecraft so it goes around the sun to meet Mars”?
