阅读理解     China will follow up on its successful mission (任务) to the far side of the moon by sending a probe to Mars next year, one of its top space scientists said Sunday. Wu Weiren, chief designer of China's lunar exploration program, said the red planet was the natural next step. "Next year we'll launch a Mars probe to orbit around the Mars, land on it and probe it," he said. China will also send another probe to take back samples from the moon's surface.     Wu's comments came as a Mars simulation(模拟) base opened in Qinghai's Qaidam Basin. According to the state-run Global Times, while the red rocky area bears a strikingly similarity to Mars, it's extremely difficult to simulate Mars due to its special natural features and hostile environment—low air pressure, strong radiation and frequent sandstorms, as well as vast differences in geography.     China didn't send its first satellite into orbit until 1970, by which time America had already landed an astronaut on the moon, but it's been catching up fast. Since 2003, China has sent six crews into space and two space labs into Earth's orbit. In 2013, China successfully landed a rover, Yutu 1, on the moon, becoming only the third country to do so.     Last December, China landed another probe and a rover, Yutu 2, on the far side of the moon. Progress has been slow going since then: due to the extreme conditions there, the rover often has to hibernate to preserve its capabilities for further exploration, Wu said. "The temperature there is minus 190 degrees Celsius, which all components and parts cannot stand. So we let it sleep for a while, making sure it can spend the night safely. A few days ago, it woke up automatically to work. We've gained lots of data in the past few days, and we're going to make the data known to the world,” Wu said. （1） What's China's next step in its space exploration? A . To get back a probe from Mars. B . To probe Mars next year. C . To land a rover on Mars successfully. D . To open a Mars simulation base. （2） Which does the underlined word "hostile" in Paragraph 2 probably mean? A . Stable. B . Uncertain. C . Unfavorable. D . Friendly. （3） What can be learned from the last paragraph? A . Yutu 2 often has to hibernate to save its energy. B . The data from Yutu 2 is accessible to the world. C . Progress has been steady in the past exploration. D . Yutu 2 can survive the moon's extreme conditions. （4） Which of the following has China achieved in exploring space? A . Two space labs have been set up. B . Six crews were sent into space in 2003. C . Samples from the moon have been taken back. D . China became the third to send a satellite to Earth's orbit. 答案： B C D A
