　　IhavegotalotofinterestingscientificknowledgefromthebooksofNationalGeographicReadingExpeditions,someofwhichareaboutlife,physics.Ireallycan’thelplosingmyselfinthecolorfulpicturesandclearwordsinthebooks.Afterreadingthebooks,Ihavebeenconsideringaquestion:

Whatifwelivedwithoutscience?

    Greatchangeshavetakenplaceintheworldwiththehelpofscience.Inthepast,lifewasnasty,brutishandshort.Itishardtoimaginehowourforefatherscoulddowithoutsomanyconveniencesthatmodernsciencebringsabout.Backthen,onlyasmallgroupofpeopleenjoyedtheveryfewcomforts.Butthemajorityofpeopledidn’tevenhavesufficientfood,letalongtheirprivilegetobeeducated.Anyway,itissciencethatchangestheworldandmakespeople’slifebetterandbetter,althoughitalsoleadstosomebadaspectsatthesametime.

　　Fromthediscoveryofthegravitytothefirststeponthemoon,wehumanbeingshaveexperiencedalongprocessofdevelopingscience.Andnow,thisprocessisstillcontinuingmuchfaster.Neworganismsarealreadybeingengineered,andnewgeneticallymodifiedcropspromisebenefitsfromhigheryieldsandlessuseofharmfulchemicalsandsoon.Alotofexamplesareshowingthispoint.Inthefuture,changesarelikelytobeevenmuchgreaterassciencereachesouttoshapelifeitself.Maybeoneday,thepossibilitythatlifeexistedonMarsbillionsofyearsagowillbepotentiallyoneofthegreatestdiscoveriesofourtime.Itistheforceofthecompetition,wehumanbeings’inquiringmindandinitiativethatbringaboutthenon-stoppeddevelopmentofscience.Therefore,itisdifficultandimpossibletopreventsciencefromchangingtheworldandourlifeaswell.
