Writing a jurnal entry sbut living in space
Read the passage and answer the questins.
In space, even the mst straightfrward, everyday tasks can be quite difficult fr astrnauts wh are spending mnths n bard a spacecraft. In this zer gravity wrld, there is n up r dwn, and while sleeping n the ceiling might sund like fun, astrnauts need t be strapped t sleeping cmpartments t prtect themselves frm injury.
Althugh nt many peple enjy ding husewrk, astrnauts need t find the self-discipline t keep the small interir f their spacecraft clean; even using a vacuum cleaner t stp dust frm getting int the air filters. A vacuum cleaner als cmes in handy fr fetching items that are flating arund ut-f-reach!Astrnauts als need t keep themselves clean. T d this, they use special sap and shamp which d nt need t be rinsed ff with water. After brushing their teeth, they spit int a twel.With n gravity t push against, astrnauts’ bnes and muscles can becme weak. In rder t stay fit, astrnauts have t exercise n a regular basis.
And while sme fd items, such as cakes and fruit can be eaten in mre r less the same way that they are n Earth, water needs t be added t much f the fd that is eaten in space. Nnetheless, a menu fr a hungry astrnaut can still be varied and balanced, ften including sup, prawn sandwiches, as well as fruit yghurt. And as salt and pepper wuld simply flat away, astrnauts are prvided with these in liquid frm. Carrying ut these everyday tasks effectively helps the astrnauts stay healthy and fcus n their wrk in space — after all, imagine what wuld happen if they caught a cld and started t sneeze!
What is the main reasn why everyday tasks are less simple in space?Why is it imprtant fr astrnauts t exercise regularly?
Everyday tasks are less simple mainly because f the zer gravity in space.
It’s imprtant fr astrnauts t exercise regularly because with n gravity t push against, astrnauts’ bnes and muscles can becme weak in space. Exercising regularly can help them stay fit.
What else d yu knw abut life n a spacecraft?
Lwer bdy lses strength, s astrnauts need t exercise every day.
The heart and bld change in space. (In space, withut the pull f gravity, the bld mves t the upper bdy and head.)
Water in the bdy als des the same thing. It makes the astrnauts’ faces lk puffy (浮肿的).

I was lucky enugh t be chsen as a visitr t the space statin! After an exciting blast int rbit, I culdn’t wait t lk thrugh the space statin windws int deep space! Yu can imagine my disappintment when I didn’t see many stars. The astrnauts laughed and explained t me that we were still in the sunlight, s f curse we culdn’t see much, because the light was t bright. Shrtly after, we passed int Earth’s shadw, and I lked ut f the windw t see the mst amazing number f stars! I felt very excited! This is the mst unfrgettable experience n the statin.
Sn after that, it was time fr dinner. The thing I nticed mst was nt the zer gravity measures fr eating, but the fact that the fd didn’t have much taste. And my nse felt blcked. It turns ut these things are related, because in zer gravity, yur face swells up mre. After that, it was time t get strapped int bed. It was a bit hard t sleep in zer gravity — my arms kept flating away, and I wke up t see them right in frnt f my face, instead f lying n the bed like they wuld n Earth.Despite even simple things being harder t d, I really enjyed being in zer gravity, and I lved being able t flat arund instead f having t walk. It’s a pity my stay n the statin was s shrt. It wuld have been great t stay lnger and learn mre abut life in space!
