B

　　Going to outer space is a little like going camping.You have to carry with you all the food and equipment you need for your trip，so your food can't be too heavy or hard to prepare.Plus，there are no refrigerators to keep food cold and fresh.

　　Food with all the water dried out is lightweight and doesn't spoil.So，many space foods are dried on Earth and stored in special packets.Some，such as dried pears，taste good right out of the packet.But to eat the turkey in this outer­space Thanksgiving dinner，an astronaut must add water and heat the packets.

　　On Earth，gravity is the force that keeps your feet on the ground and your sandwich on your plate.But there's no gravity in space.To keep food from floating away，astronauts on the Space Shuttle attach the packets to a special tray.The tray can be fixed to a wall or to the astronaut's lap.To prepare their food，astronauts use liquid forms of salt and pepper.The liquid sticks to the food better.Regular salt and pepper would float away，maybe up an astronaut's nose.Achoo!

　　Liquids float right out of cups and glasses，though.So astronauts drink everything from a small bag with a straw(饮料吸管) that can be closed.Astronauts say that most space foods taste pretty good.Some，such as apples and pudding are the same as the foods you eat on Earth.

　　Astronauts eat tortillas(玉米粉圆饼) instead of bread because they make fewer crumbs(碎屑)．Floating crumbs could get stuck in equipment or an astronaut's eye.
