根据短文内容，回答下列问题。 I think the Dream (梦想号) is the best ship in the world now. What is the Dream like? The ship is very beautiful. There are different rooms on the ship-the first class (头等舱), the second class and the third class. The first class rooms are the best rooms. People can do some sports if they want. There is a swimming pool and a gym on the ship. There are also many restaurants on it. People can eat their favorite food. If they feel bored, they can listen to music. If they like quiet places, they can go to the libraries. There are two libraries on the ship. One is for the first class, and the other is for the second class. The people of the third class can't go to the libraries. 1. What is the name of the ship in this story? 2. Which is the best, the first class, the second class or the third class? 3. Is there a computer room on the ship? 4. How many libraries are there on the ship? 5. Can all the people go to the libraries?
