　　第三步：连接过渡成篇

　　If I visited the moon, there would be a problem I might be faced with: how to eat and drink.

　　On the earth, it is easy for us to eat and drink. But on the moon, the gravity is so weak that the food will float around. I would have to take all my food with me if I went to the moon.

　　So it could be put in a tube and then I would be able to suck it more easily. Perhaps I would use a straw to do it. It can prevent the food from floating away.

　　Only in this way would the problem be solved. I will have a try in time.
