Eating: Astronauts in. a space*hip face a choice because of no gravity (引力). They may pick their food, use their hands and put it into their mouths. Or they may let the food stay in the air. Then they float (漂浮) to the food and get it with their mouths. Astronauts have to re-member to close their mouths tightly (紧紧地) while eating. Any crumb (碎屑) could cause big trouble. Bits of food that stay in the air can go into astronauts' noses when they are breathing.

Sleeping: Shenzhon VI astronauts sleep on the wall of the spaceship. People float in a spaceship where there isn't any gravity. So scientists fix (固定) sleeping bags to tbe wall tohelp astronauts.
