The vacation in space will include, firstly, an eight-week training course on an island, then rocket transport between the earth and your hotel in space, and finally a three-day stay and a return rocket trip. So, what will the cost be? For a vacation in space, guests will pay about 4.5 million US dollars. The hotel will consist of a space pod accommodating four paying guests and two astronauts. During the three days when the pod is in orbit 450 kilometers above the earth, guests will be able to look out and see the sun rise 15 times a day and travel around the world every 80 minutes. Inside the space pod, in order to beat the effects of weightlessness, they will wear special spacesuits so that they can attach themselves to the spacecraft walls. Or, if they prefer to move around in the weightless atmosphere, they can float in the pod. It all sounds so exciting that regardless of the expense, more than 200 people have expressed an interest in a space vacation, and many of them have already made reservations.1.How long will tourists spend to complete a space vacation?A.Eight weeksB.Three daysC.About eight weeks and three daysD.Not mentioned2.Can ordinary tourists afford to stay in a space hotel?A.Yes, they canB.No, they can’tC.Guests will pay about 4.5 million US dollarsD.Not mentioned3.While in space, where will tourists stay and what can they experience?A.They will stay in the pod in orbit 450 kilometers above the earth and they can experience floating.B.They will stay in the rocket transport and they can see the sun rise 15 times a day and travel around the world every 80 minutes.
