一、阅读下面的文字,完成1～4题。太空弹弓张唯诚月球将成为人类走出太阳系的重要基地。人类花了漫长的岁月将宇航员送上了月球,而现在我们又将花费1/4世纪的时间重返月球,并在那里建立一个永久的太空基地。其主要目的之一就是以月球为跳板探索更加遥远的星空。科学家可能还会把一些机器人送到月球上,它们要在岩石和土壤中提取氢和氧,以便制造出可供火箭使用的燃料。人们预测,第一个建立在地球之外的燃料站会首先出现在月球
First, read the following text and complete 1 to 4 questions. Space Slingshot Zhang Wei Cheng’s moon will become an important base for human beings to step out of the solar system. It took humans a long time to send astronauts to the moon, and now we will spend a quarter of a century returning to the moon and establishing a permanent space base there. One of its main purposes is to use the moon as a springboard to explore more distant stars. Scientists may also send some robots to the moon, where they extract hydrogen and oxygen from rocks and soil to make fuel available to rockets. People predict that the first fuel station built outside the Earth will first appear on the Moon.
