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!
( )7. 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
( )8. 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.
( )9. 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
( )10. 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
