2、 three times on our journey and that the first change would be the most powerful. Then we were off. As the rocket rose into the air, we were pushed back into our seats because we were trying to escape the pull of the earths gravity. It was so hard that we could not say anything to each other. Gradua
3、lly the weight lessened and I was able to talk to him. “Why is the spaceship not falling back to the earth? On the earth if I fall from a tree I will fall to the ground.” I asked.“We are too far from the earth now to feel its pull，” he explained, “so we feel as if there is no gravity at all. When we

8、力量慢慢减小，我才能够同他讲话。我问道：“为什么宇宙飞船不会落回到地球呢？在地球上的时候，如果我从树上掉下来，总会朝地上落下去的。”李彦平解释说：“现在我们离地球太远了，感觉不到地球的拉力，所以我们感觉好像完全没有地球引力了。当我们更接近月球时，就会感到月球的引力在拉我们。但是月球的引力不像地球的引力那么大。”我立刻感到很高兴，由于失重我在太空舱里飘来飘去，我望着(身后的)地球越来越小，而(前方的)月球越来越大。When we got there, I wanted to explore immediately. “e on，” I said. “If you are right, my we
9、ight will be less than on the earth because the moon is smaller and I will be able to move more freely. I might even grow taller if I stay here long enough.

10、 twice as far as on the earth and fell over. “Oh dear，” I cried, “walking does need a bit of practicenow that gravity has changed.” After a while I got the hang of it and we began to enjoy ourselves.Leaving the moons gravity was not as painful as leaving the earths. But returning to the earth was ve
11、ry frightening.We watched, amazed as fire broke out on the outside of the spaceship as the earths gravity increased. Again we were pushed hard into our seats as we came back to land. “That was very exhausting but very exciting too，” I said. “Now I know much more about gravity! Do you think we could

14、爬下来。但当我试图往前走时，我发现自己被带到一个步幅相当于地球上两倍远的地方并且摔倒了。“天哪，”我大声说，“重力改变了，看来走路的确需要练一练了。”过了一会儿，我才掌握了走路的诀窍，我们这才开始感到自如了。摆脱月球引力不像摆脱地球引力那样痛苦。但是返回到地球的经历却是非常吓人的。我们惊奇地看着，随着地球引力的增加，宇宙飞船的外层燃烧起火。当我们回到地面时，我们又(感到)被重重地推回在座位上。我说道：“真是精疲力尽了，但也很激动人心。关于引力，我现在就懂得更多了！你认为下次我们可以去别的星球上游览吗？”“当然可以，”他笑着说，“你想到哪颗星球上去呢？”Step 1True (T) or Fal
