Life on a space station The daily life in space differs from that on the Earth—the low gravity definitely makes ordinary things strange! Due to the near 1.absence(absent) of gravity in space，we have to attach ourselves so that we don't float around.We usually sleep in private quarters，2.which are more like large cupboards，or in sleeping bags.Our main mission in space is 3.to conduct (conduct) scientific research.We need to evaluate the effects of low gravity 4.on animals and plants.The space station needs a lot of maintenance，so we 5.constantly (constant) check support systems and do some cleaning. The most 6.challenging (challenge) work is performing tasks outside the space station，such as testing new equipment，monitoring scientific experiments or repairing the space station.Most food in space 7.is dried (dry) or freeze­dried because fresh fruit and vegetables can only be delivered to the space station from the Earth every couple of months.8.Considering(consider) low­gravity's negative effects，we discipline ourselves to do at least two hours of exercise every day.Exercise in space is not your average workout.We have to be tied onto specially 9.designed (design) exercise equipment to stop ourselves from floating around. As the space station travels at 10. a speed of about 17，500 miles per hour，we get to see the sunrise every 90 minutes.In these precious moments，all the challenges of life in space seem worth it. 学科网（北京）股份有限公司 $$
