Letusknowhowthesepeoplehavehelpedtomakeadifferenceinyoureyes.

ThepersonIrespectmostisthegeophysicistHuangDanian,whohelpedChinatomakemanytechnologicaladvances.

Huangwasaremarkablescientist.HehadstudiedandworkedinBritainfor18years,butwhenhefeltthathiscountryneededhim,hegaveuphiswell-paidjobandreturnedtoChina.Overthenextsevenyears,Huangworkedtodevelopmanydevicesneededfordeep-seaexploration.

Unfortunately,suchachievementsdidn'tcomecheap.Duetothefranticpaceofhisresearch,Huangwasabsentfromhisfather'sfuneral,andevenhisowncancerwentundetectedashehadnotimetoseeadoctor.Tosumup,Huangsacrificedeverythingforhisresearch,andIthinkmorepeopleshouldhonourhim.

Unit2LOOKINGINTOTHEFUTURE

CLONING:

WHEREISITLEADINGUS?

Whenitwasannouncedin2018thattheChineseAcademyofSciencesinShanghaihadcreatedtheworld'sfirstclonedmonkeys,ZhongzhongandHuahua,heateddiscussionsfollowedonline.Infact,cloninghasalwaysbeenwithus.Itisawayofmakinganexactcopyofanotheranimalorplant.Ithappensinplantswhengardenerstakecuttingsfromgrowingplantstomakenewones.Italsohappensinanimalswhenidenticaltwinsareproducedfromthesameegg.Thesearebothexamplesofnaturalclones.

Cloninghastwomajoruses.First,gardenersuseittoproducelargequantitiesofplantsforsale.Second,itisvaluableforresearchonnewplantspeciesandformedicalresearchonanimals.Cloningplantsisfairlystraightforward,whilecloninganimalsismuchmorecomplicatedanddifficult.Overtheyears,manyscientistsfailedintheirattemptstocloneanimals,buttheirdeterminationandpatiencepaidoffin1996withabreakthrough—thecloningofDollythesheep.

Thesheepcloningprocedureworkslikethis:

FemalesheepAprovidesaneggcell.

Thenucleusisremovedfromtheeggcell.

Theeggcellisreadyforanewnucleus.

FemalesheepBprovidesasomaticcell（体细胞）fortheclone.Thenucleusofthiscellcontainsallthegenesneededtoproduceanewsheep.Thenucleusistakenoutofthesomaticcell.

Withtheadvancesofscientificresearch,cloningwillhaveseveralmajorusesinthefuture.Foronething,itcouldbeusedtobreedanimalspecieswhichareendangered,orevenbringbackspecieswhicharenowextinct.Foranother,itcouldbeusedtogrowhumanorgansortissueinanimals,whichcouldbeusedforhumanorgantransplantsormedicaltreatments.Finally,cloningcouldbeusedtobreedanimalsthatwillprovideuswithhigherqualitymeat,milk,oreggs.
