The strangeness of living in space is apparent from the moment we sleep.Due to the near absence of gravity in space, we have to attach ourselves so that we don't float around.We usually sleep in private quarters, which are more like large cupboards, or in sleeping bags attached to the walls or the ceiling.It's strange that we try to sleep with no pressure against our back, but the unusual beds don't bother us any more.After about eight hours of sleep, we start our day of work. The routine tasks that occupy most of the day are demanding, but they can also be extremely rewarding.Our main mission is to conduct scientific research.We need to evaluate the effects of low gravity on animals and plants.Creatures such as mice, fish and mosquitoes have also been sent to the station! In a low-gravity environment, we can learn more about changes in cells and microorganisms under the microscope. ?[高频词汇] [佳句背诵] ●阅读理解 1．What makes ordinary things strange The low gravity. 2．Why do astronauts have to attach themselves while sleeping Due to the near absence of gravity in space.
