A. water B. ice C. plants D. life 四、阅读短文，选择正确答案： 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 Earths, 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!1. Mars _.A. isnt one of the planets in our solar systemB. is farther from the sun than the earthC. never meets Earth closeD. and Earth have the same orbit around the sun2. The time Mars takes to go around the sun is _ that Earth needsA. as long asB. not so long as C. as about two times long asD. as about three times long as3. 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.4. 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 5. From the passage, we can know the next perihelic opposition _.A. is the closest approach in almost 60,000 yearsB. will bring Earth and Mars even fartherC. will happen on August 28, 2287D. is in 2003五、根据句意及中文意思或英语解释写出句中所缺的单词：1.

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 motion 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.1Do scientists have an opportunity to launch a spacecraft to Mars every 26 months?_2. If a spaceship wants to escape Earths gravitational pull, what does it need?_3When can the spacecraft get to Mars by the scientists opinion?_4Who described the physical laws that were mentioned in the passage in the 17th century?_5Whats the Chinese meaning of the sentence “What you want to do is launch the spacecraft so it goes around the sun to meet Mars”?_九、根据短文及首字母提示，填入适当的词：Welcome to the Mars shuttle!
