　　第五步：过渡衔接联成篇

　　If I went to travel in space, there would be a problem I might be faced with: how to eat and drink in outer space.

　　I would have to take all my foods with me if I went to space travel, but in outer space, the gravity is so weak that the food will float around if it is solid.I must make sure that it is specially made as liquid space food.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 eat it.It can prevent the food from floating away.Only in this way would the problem be solved.I might have a happy visit to space in that way.I will have a try in time.
