译文：女士们，先生们，下午好！谢谢大家来听这个讲座。在我的职业生涯中，我见证了许多了不起的科学发展，但没有一个能像基因组编辑那样具有颠覆性。我对这一科学进步能带来的可能性感到万分激动，我希望今天能与你们分享我激动的心情。职业生涯as…as…结构定语从句Racewalkingdoesnotpoundthebodyasmuchasrunningdoes.Asmanyofyoumayalreadyknow,genesplayacriticalroleinshapingourlives.Everythingfromthecolorofoureyestoourtalentformathsdependsongenes.Thecompletesetofgenesinsideacelloralivingbeingiscalledagenome.Ourownpersonalgenomecarriesalltheinformationneededtomakeusgrowanddevelop.Italsocontainsinformationthathelpsdetermineourlifespanandaffectsourchancesofcontractingcertaindiseases.Somepeople,forexample,carryagenethatmakesthemmorelikelytocatchacertainvirusordevelopaparticularformofcancer.起至关重要作用译文：你们可能已经知道，基因在塑造我们的人生方面起着至关重要作用。从眼睛的颜色到我们的数学天赋，一切都取决于基因。基因组是指一个细胞或生物体内的一整套基因。我们的个人基因组携带着我们成长和发展所需的所有信息。它（基因组）还包含其他信息，这些信息有助于决定我们寿命的长短并影响我们患某些疾病的概率。例如，有些人携带着一种让他们更有可能感染某种病毒或患上某种癌症的基因。后置定语affectvt.短语变形affectsb./sth.beaffectedby…受……影响affection
