performern[C]表演者；执行者exchange的词源义是“actofreciprocalgivingandreceiving”。它是由前缀ex-(out)和change组成，可以理解为“拿……出去换成……”，其基本义是“交换”。在原始社会，人们“物物交换”，交换自己所需要的物资。但是有时候受到用于交换的物资种类的限制，不得不寻找一种能够为交换双方都能够接受的物品，这种物品就是最原始的货币。随着商品生产和交易量逐渐增大，商人们为了谈生意就必须商定一个固定的地点定期会见，就产生了“交易所”。expressexplain表达解释ex-意为“out向外”ex-+change=？exchange■n

[C]&[U]交换；交流：anexchangestudentWouldyoulikemyoldTVinexchangeforthiscamera

[C](商品的)调换：Thestore’spolicyisnottoallowreturnsorexchanges.foreignexchange

[U](货币的)兑换：

[C]交易所：NewYorkStockExchange人与人或物与物之间的“交换”商品之间的“交换”货币之间的“交换”exchange语义网络图交换；交流(商品的)调换

(货币的)兑换交易所nv交换；交流更换；兑换交换基本义exchange“交换”的场所

交换；交流：exchangeviews/ideasBeforegraduation,studentsexchangepresentswitheachother.■vt“交换”时与with搭配“更换”时与for搭配

更换；兑换(change)：I’dliketoexchangethisdressforoneinalargersize.Youcanexchangeyourcurrencyfordollarsinthehotel.

拓展这是特朗普和希拉里在2016年竞选美国总统时的情形。据说这是美国史上最没底线的总统大选辩论。Why因为TrumpandClintonexchangedheavilyinpersonalattacks.exchange的意义由交换具体的人或物到交换抽象的东西如思想或信息的转变。如果双方心平气和地交换思想或信息，可称为“交流”。如果双方怒气冲冲地交换的内容是人身攻击(personalattacks)，严肃的说法是“争论”，通俗的说法是“互撕”。PART01随堂检测improve翻译下列句子。1.他在学校的表现进步很大。__________________________________2.我们相信，通过我们进一步的努力环境将会得到改善。_______________________________________________3.我已经很努力来提高英语水平。__________________________________Hisperformanceatschoolhasgreatlyimproved.Weareconfidentthattheenvironmentwillbeimprovedbyourfurtherefforts.I’vetriedveryhardtoimprovemyEnglish.rate根据所给汉语，用适当的词块完成下列句子。1.Thecountry’s_____________(出生率)felltoarecordlowlastyear.2.Well,that’sonegoodpieceofnews____________
