2、 to me that the force of gravity would change 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

3、 could not say anything to each other. Gradually 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 f

8、在努力挣脱地球的引力，我们被向后推在座位上。这种引力太强了，以至于我们彼此间都不能说话了。渐渐地，这个力量慢慢减小，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 im

9、mediately. “Come on，” I said. “If you are right, my weight will be less than on the earth because the moon is smaller and I will be able to move more freely.

10、ut when I tried to step forward， I found I was carried 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

11、 leaving the earths. But returning to the earth was very 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

12、I know much more about gravity! Do you think we could visit some stars next time？”“Of course，” he smiled, “which star would you like to go to？”come on快点儿。常用于祈使句中以鼓励某人，意为“动手吧；快点儿；加油”。step forward朝前走；迈步向前twice as far as“的两倍远”。倍数表示法：倍数(twice, three times .)asadj./adv.as。fall over跌倒；摔倒动名词walking在此处作主语。d
