譯文：女士們，先生們，下午好！謝謝大家來聽這個講座。在我的職業(yè)生涯中，我見證了許多了不起的科學(xué)發(fā)展，但沒有一個能像基因組編輯那樣具有顛覆性。我對這一科學(xué)進(jìn)步能帶來的可能性感到萬分激動，我希望今天能與你們分享我激動的心情。職業(yè)生涯as…as…結(jié)構(gòu)定語從句Racewalkingdoesnotpoundthebodyasmuchasrunningdoes.Asmanyofyoumayalreadyknow,genesplayacriticalroleinshapingourlives.Everythingfromthecolorofoureyestoourtalentformathsdependsongenes.Thecompletesetofgenesinsideacelloralivingbeingiscalledagenome.Ourownpersonalgenomecarriesalltheinformationneededtomakeusgrowanddevelop.Italsocontainsinformationthathelpsdetermineourlifespanandaffectsourchancesofcontractingcertaindiseases.Somepeople,forexample,carryagenethatmakesthemmorelikelytocatchacertainvirusordevelopaparticularformofcancer.起至關(guān)重要作用譯文：你們可能已經(jīng)知道，基因在塑造我們的人生方面起著至關(guān)重要作用。從眼睛的顏色到我們的數(shù)學(xué)天賦，一切都取決于基因。基因組是指一個細(xì)胞或生物體內(nèi)的一整套基因。我們的個人基因組攜帶著我們成長和發(fā)展所需的所有信息。它（基因組）還包含其他信息，這些信息有助于決定我們壽命的長短并影響我們患某些疾病的概率。例如，有些人攜帶著一種讓他們更有可能感染某種病毒或患上某種癌癥的基因。后置定語affectvt.短語變形affectsb./sth.beaffectedby…受……影響affection
