Let’s see how astronauts live and work on the space station. Eating is not a problem for astronauts now. They can choose from many kinds of food, like fruit, nuts, chicken and even seafood. They also have tea, juice and soup. But all the food is specially made to be eaten in space, and they can’t have food that crumbles (碎屑) easily. Sleeping is also different. Astronauts have to sleep in sleeping bags that are stuck to the wall. If they don’t, they will float around the room and might hit something by mistake. They usually sleep in a small room, just like a tiny bedroom. Exercising is very important. In space, astronauts start losing muscle because of no gravity. Exercise can slow down this muscle loss. They use special exercise equipment in the small gym on the station to stay fit. Working in space is busy and sometimes stressful. Astronauts do many experiments every day. When they go outside the station for a spacewalk, they have to move very carefully. They can’t make any mistakes, or it will be dangerous. 1. Why can’t astronauts eat food that crumbles easily? A. Because it is not healthy. B. Because crumbs will float everywhere and cause problems. C. Because they don’t like the taste. D. Because there is no way to keep the food fresh. 2. What do astronauts do to stop themselves from floating around while sleeping? A. They sleep on a bed. B. They tie themselves to the floor. C. They sleep in sleeping bags stuck to the wall. D.
