underthemicroscope.日常工作占用了一天里大部分时间，要求很高，但它们也会非常有意义。我们的主要任务是进行科学研究。我们需要评估低重力对动植物的影响。诸如老鼠、鱼、蚊子等生物也被送到了空间站！在低重力环境下，我们可以通过显微镜更多地了解细胞和微生物的变化。para.3Aswellasdoingthesebiologicalexperiments,wecarryoutexperimentsinotherresearchfields.IhavebeenworkingononeexperimentwhichlocatesandtrackslightningoverlargeregionsoftheEarth.Hopefully,itwillcastnewlightontheEarth'sclimateandleadtobetterlightningprotection.Withsomuchgoingon,thespacestationneedsalotofmaintenance,soweconstantlychecksupportsystemsanddosomecleaning.除了做这些生物实验，我们还开展其他研究领域的实验。我一直在做一个实验，可以定位并追踪地球上大片区域的闪电。希望这个实验能使人们进一步了解地球气候，并更好地做好雷电防护。空间站里发生那么多事情，需要大量的维护，所以我们经常检查空间站的支撑系统，并做一些清洁工作。para.3Themostchallengingworktakesplacewhenweneedtoperformtasksoutsidethespacestation,suchastestingnewequipment,monitoringscientificexperimentsorrepairingthespacestation.Inthecircumstances,it'stimeforaspacewalk.First,weputonourspacesuits,whichallowustobreatheinspaceandprotectusfromexposuretothecoldandradiation.当我们需要在空间站外面执行任务时，例如测试新设备、监测科学实验或修理空间站,就会产生最具挑战性的工作。在这种情况下，是时候来场太空行走了。首先，我们穿上太空服，它们可以让我们在太空中呼吸，保护我们免受寒冷和辐射的伤害。para.4Thenweheadout,andsometimes

everycoupleofmonths.考虑到低重力环境，太空中的饮食也大不相同。大多数食物都是脱水或冻干的。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只能每隔几个月从地球运到空间站。para.5Saltandpepperareonlyinliquidform,sothattheywillnotfloatawayandblocktheairpipes.However,liquidscan’tbeeasilycontrolledinspace.Wemustdrinkwateroranyotherliquidsoutofabagthroughathintubeofplastic.Furthermore,tokeepourbodyhealthy,wemustensureabalancedsupplyofnutrientsbytakingpills.盐和胡椒粉仅以液体的形式存在，这样它们就不会飘来飘去，堵塞通气管。但是，液体在太空中不容易控制。我们必须用塑料细管，从袋子里面喝水或其他液体。此外，为了保持身体健康，我们必须吃药来保证营养的均衡补给。para.5ExercisingWhyandhowdoastronautshavetoexerciseinthespacestation?Whataboutthefrequency?1.Itisofvitalimportancetotheirhealthtoavoidthelossoftheamountofmuscleandbonemass.3.Theydisciplinethemselvestodoatleasttwohourseveryday.
