Scientists can look at them through telescopes(望远镜) and, in this way, they can find out a great deal(许多，大量). They know many facts about the moon. For example, they know how big and how far away it is. ②The moon is about 384,000 kilometers away from the earth. A plane cannot fly to the moon because there is no air. But a rocket can. “How can a rocket fly?” If you want to know, get a balloon and then blow it up, until it is quite big. Do not tie up the neck of the balloon, let it go! The balloon will fly off through the air very quickly. The air inside the balloon tries to get out through the neck of it, which pushes(推动)the balloon through the air. It does not need wings(翅膀)like a plane. ③___________________ Of course, the rocket is made of(由……制成) metal(金属). The metal must not be heavy but it must be very strong. There is a gas(气体) inside the rocket which is made very hot. When it rushes out of the rocket, the rocket is pushed up into the air. 1.将划线部分①改为同义句：___________________ 2.将划线部分②译成汉语：___________________ 3.从下面三个句子选出一个，将其放回到划线部分③，使其上下文通顺，合理。 A.
