Can you imagine astronauts ' everyday life in space? They also need to eat, s, exercise and relax. They do the same things as us, but they do tdifferently.
On the e, we put food on a plate. Gravity（重力） holds the food down and keeps it on the plate. But there is almost no gravity in space, so f can float （漂浮） away, and astronauts must eat carefully.
In space, sleeping is very different f that on the earth. Some a
like to float in the air, but most like to be in a sleeping bag. They tie （系） the bag to a wall so that they won ' t float away at night.
Exercise is very i in space. On the earth, your legs carry your body, but in space, astronauts float, so they do not u their legs often. This is very bad for their legs, so they must e for thirty minutes every day.
After a day ' s work, astronauts relax. They may listen to music, read, watch films, play games, or talk to their friends and families on the earth. Sometimes they just e floating in the air. How interesting !
