牛津上海版（试用本）同步练习 一、阅读理解-阅读选择（共1小题） The question whether there is life on Mars has made the public think a lot for more than a century. The closest look showed Mars to be a dusty, cold world, covered by air too thin to breathe. A British spaceship and Europe's Mars spaceship plan to land on Mars or enter orbit (轨道) around it. One of the NASA's (美国宇航局) spaceships is expected to land on Mars, the other is going to land on the opposite side of Mars later. Since 1960, over twenty spaceships sent to Mars have failed. Most have been lost on flying up or landing because those are the most difficult times of any flights. Scientists wanted to find out whether there was water on Mars. A team of scientists reported that Mars had been a dry wasteland. But weeks later, a second team reported differently that they had found some marks showed clearly that they were made by the rivers. Such marks told us that Mars was a warmer place billions of years ago—just as life first appeared here on the Earth.
