We visited the moon in our spaceship④！Before we left, Li Yanping explained to me⑤that the force of gravity⑥would change three times on our journey and that the first change would be the most powerful. Then we were off⑦. As the rocket rose into the air, we were pushed back into⑧our seats because we were trying to escape the pull⑨of the earth's gravity. It was so hard that we could not say anything to each other ⑩. Gradually⑪the weight lessened⑫and I was able to talk to him. “Why is the spaceship not falling back to⑬the earth? On the earth if I fall from a tree I will fall to the ground.”I asked.“We are too far from⑭the earth now to feel its pull，”he explained, “so we feel as if there is no gravity at all. When we get closer to⑮the moon, we shall feel its gravity pulling⑯us, but it will not be as strong a pull as⑰the earth's.”I cheered up⑱immediately and floated⑲weightlessly⑳around in our ①名词visit后接to，意为“到……的旅行”，to为介词。

We were amazed to watch the fire_________on the outside of the the space.Now I know much more about gravity.Going through the articleLast month I was lucky enough to have a chance to make a trip into space with my friend Li Yanping, an astronomer. We visited the moon in our spaceship! Before we left, Li Yanping explained to me (that) the force of gravity would change three times on our jounary and that the first changed 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 earth’s gravity. It was so hard that we 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 feel as if there is no gravity at all. When we get closer to the moon, we shall feel its gravity pulling us, but it will not be as strong a pull as the earth’s ” . I cheered up immediately and floated weightlessly around in our spaceship cabin watching the earth become small and the moon larger.When we got there, I wanted to explore immediately. “Come on,” I said. “If you are right, my weight will be less than on the earth because the moon is smaller and Iwill be able to move more freely. I might even grow tall if I stay here long enough. I shall certainly weight less!”Ilaughed and climbed down the steps from the spaceship. But when I tried to step forward, I found I was carried twice as far as on the earth and fell off. “Oh dear,” Icried, “walking does need a bit of pratice now that grativity has changed.”After a while I got the hang of it and we began to enjoy ourselves.Leaving the moon’s gravity was not as painful as leaving the earth’s. But returning to the earth was very frightening. We watched, amazed as fire broke out on the outside of the spaceship as the earth`s 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 grativity! Do you think we could visit some stars next time?”“Of course ” he smilded, “which star would you like to go to? ”。
