working on one experiment which locates and tracks lightning over large regions of the Earth.在低重力环境下，我们可以在显微镜下更多地了解细胞和微生物的变化。除了做这些生物学实验，我们还进行其他研究领域的实验。我一直在做一个实验，定位和跟踪地球上大片地区的闪电。开展实验，做实验开展实验，做实验在显微镜下在显微镜下Hopefully,it will cast new light on the Earths 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

circumstances,its time for a spacewalks.最具挑战性的工作发生在我们需要在空间站外执行任务时，如测试新设备、监测科学实验或维修空间站。在这种情况下，是时候来场太空行走了。para.4发生发生v.执行，做执行，做在这种情况下在这种情况下是时候做某事是时候做某事First,we put on our spacesuits,which allow us to breathe in space and protect us from exposure to the cold and radiation.Then we heat out,and sometimes perform tasks for hours at a time,with the beautiftul Earth visible

space.Most food is dried or freeze-dried.Its a luxury to eat fresh food,because fresh produce such as fruit and vegetables can only be delivered to the space station from the Earth every couple of months.鉴于低重力环境，太空中的饮食也是不一样的。大多数食物是脱水或冻干的。吃到新鲜的食物是一种奢侈，因为水果和蔬菜等新鲜农产品每隔几个月才能从地球运送到空问站。para5鉴于鉴于v.运载，递送，发布运载，递送，发布每隔几个每隔几个是一种奢侈Salt and pepper are only in liquid form,so that they will not float away and
