选必3 Unit2 Reading: Life on a space station Living in space is every would-be astronaut's dream. My six-month stay on a space station has come to an end, and it has been a challenging but magical adventure. I bet you'd love to know what daily life is like up in space and how it differs from that on the Earth—the low gravity definitely makes ordinary things strange! 1. would-be astronaut's dream准宇航员的梦想 2. a challenging but magical adventure. 充满挑战但神奇的冒险 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 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.As well as doing these biological experiments, we carry out experiments in other research fields. I have been working on one experiment which locates and tracks lightning over large regions of the Earth. Hopefully, it will cast new light on the Earth's climate and lead to better lightning protection. With so much going on the space station needs a lot of maintenance, so we constantly check support systems and do some cleaning. 6. The routine tasks that
