1524年，一位鲜为人知的意大利人维拉萨诺驾船驶进纽约港，并将该港名为安古拉姆。他对该港作了这样的描述：“地理位置十分适宜，位于两座小山的中间，一条大河从中间流过”。虽然维拉萨诺绝对算不上一个伟大的探险家，但他的名字将流芳百世，因为1964年11月21日建成的一座世界上最长的吊桥是以他的名字命名。维拉萨诺大桥由奥斯马.阿曼设计，连结着布鲁克林与斯塔顿岛，桥长4,260英尺。由于桥身太长，设计者不得不考虑了地表的形状。两座巨塔支撑着4根粗大的钢缆。塔身建在巨大的水下钢盘混凝土平台上。平台深入海底100英尺。仅这两座塔就花了16个月才建成。塔身高出水面将近700英尺。高塔支撑着钢缆，而钢缆又悬吊着大桥，4根钢缆中的每根由26，108股钢绳组成。据估计，若桥上摆满了汽车，也只不过是桥的总承载力的1/3。然而，这座桥重要特点不仅是它的规模与强度。尽管此桥很大，但它的结构简单，造型优美，实现了设计者企图创造一个“尽量用细线条勾画出一个庞然大物”的梦想。Verrazano,anItalianaboutwhomlittleisknown,sailedintoNewYorkHarbourin1524andnameditAngouleme.Hedescribeditas"averyagreeablesituationlocatedwithintwosmallhillsinthemidstofwhichflowedagreatriver."ThoughVerrazanoisbynomeansconsideredtobeagreatexplorer,hisnamewillprobablyremainimmortal,foronNovember21st,1964,thelongestsuspensionbridgeintheworldwasnamedafterhim.TheVerrazanoBridge,whichwasdesignedbyOthmarAmmann,joinsBrooklyntoStatenIsland.Ithasaspanof4,260feet.Thebridgeissolongthattheshapeoftheearthhadtobetakenintoaccountbyitsdesigner.Twogreattowerssupportfourhugecables.Thetowersarebuiltonimmenseunderwaterplatformsmakeofsteelandconcrete.Theplatformsextendtoadepthofover100feetunderthesea.Thesealonetooksixteenmonthstobuild.Abovethesurfaceofthewater,thetowersrisetoaheightofnearly700feet.Theysupportthecablesfromwhichthebridgehasbeensuspended.Eachofthefourcablescontains26,108lengthsofwire.Ithasbeenestimatedthatifthebridgewerepacedwithcars,itwouldstillonlybecarryingathirdofitstotalcapacity.However,sizeandstrengtharenottheonlyimportantthingsaboutthisbridge.Despiteitsimmensity,itisbothsimpleandelegant,fulfillingitsdesigner'sdreamtocreate"anenormousobjectdrawnasfaintlyaspossible".Part4Writing互联网给我们提供了大量的信息，也让我们的日常生活越来越便捷了，但如果我们沉迷于网络，它也会成为问题的根源。参考第15课第2句一些花钱如流水的年轻人可能永远都不会想到，他们用来买一双鞋的钱可以供父母花很长一段时间。参考第15课第3句与其把偶像名字纹在身上，或者在听到他们婚讯的新闻时心碎不已，我们能用另外的方法表达自己的对偶像的爱。比如，我们可以从名人身上汲取力量，他们依靠艰苦努力才取得了名声和财富，并努力成为更好的人。参考第15课第二段第2句人们以前总是认为只要是外国的就都是好的，我们必须从这种惯性思维中跳出来。与此同时，我们要善于发现我们文化中的闪光点，这一点很重要。参考第15课倒数第2句互联网给我们提供了大量的信息，也让我们的日常生活越来越便捷了，但如果我们沉迷于网络，它也会成为问题的根源。Theinternethasprovidedanamplesupplyofinformationforusandmadeourdailylifemuchmoreconvenient,butitcanalsobeasourceoftroubleifwegetaddictedtoit.一些花钱如流水的年轻人可能永远都不会想到，他们用来买一双鞋的钱可以供父母花很长一段时间。Withsomeyoungsterswhosquandertheirmoney,itneveroccurstothemthattheamountofmoneytheyspendonapairofshoe
