血压大有裨益，鸡蛋与胃酶结合后产生的蛋白质与降压药物有着同样的功效。16．A　推理判断题。第一段的后半部分提到鸡蛋产生蛋白质的作用与强效降血压药物类似，此处与之相呼应，表示鸡蛋与胃酶结合后产生蛋白质的作用与药物相当。由此可推知“ACEinhibitors”是一种药。17．C　细节理解题。根据倒数第二段最后一句的内容可知，Bruce教授认为鸡蛋属于健康食物。-8-\n18．D　推理判断题。最后一段的最后一句提到几乎一半的英国人相信对鸡蛋的限制仍然适用，由此可推断这些人依旧认为每天吃一个鸡蛋对健康有害。19．A　主旨大意题。本文是一篇研究报告，第一段是文章的中心段，通读全文可知，本文意在介绍关于鸡蛋的科学发现。B文章主要讲述了AmosPeters观察到松鼠在觅食时遇到交通带来的危险，他还看到一只死了的松鼠嘴里还含着食物，他设想要为松鼠们设计一个能保证它们安全的桥。后来通过努力这个桥终于设计成功，并为世界所知，引起国际的关注，成为当地的一道风景。20．D　细节理解题。第二段的“…togivesquirrelsawaytocrossthebusyroadwithoutgettingflattenedbypassingcars.”看出建这座桥是为了保证松鼠的安全。故选D。21．B　推理判断题。题干关键词为“coffeebreakdiscussion”。由第四段“andthatday'scoffeebreakdiscussionturnedintosquirrelsafety.ThegroupofbusinessmencookedupthesquirrelbridgeideaandformedacommitteetoasktheblessingoftheCityCouncil.”可以看出在此期间，建松鼠桥的想法产生了。故选B。22．D　词义猜测题。根据本句的“Squirrelswereevenseenguidingtheiryoung”看出，是教小松鼠如何使用这个桥。故选D。23．C　细节理解题。倒数第二段的“Repairsweremadeandcrosspieceswerereplaced”看出数年之后，这座桥得到了重修。故选C。24．A　推理判断题。从最后一段的Petersdiedin1984,andatenfootwoodensquirrelsculpturewasplacednearthebridgeinmemoryofitsbuilderandhisdevotiontotheproject.看出，人们在桥附近修建雕像来纪念AmosPeters对动物的这份爱心。故选A。Ⅲ.25.before　26.much　27.up　28.success29．standing　30.included　31.different/difficult32．between　33.unforgettable　34.life仔细观察下面图画，请你给China-8-\nDaily写一篇100字左右的短文，描述一下你在路上所见的事，并就骑车人--李平的行为，简单阐明自己的感想。参考范文OnePossibleVersionOnedayLiPingwasridingfastwhenshesuddenlysawanoldwomanbeforeher.Butitwastoolatetostopimmediately.Theoldwomanwasknockeddown.LiPindidn'thelpher.Instead,shescoldedherandrodeaway.WhenLiPingstoppedherbicycle,shewassurprisedtofindhernewshoesmissing.Shehurriedbackandfoundtheoldwomanthereholdinghershoesinherhands.Shewassorryforwhatshehaddoneandapologizedtothewoman.Fromthis,Ilearnedeverybodyshouldbekindtoeachother.NeverdoasLiPindidtotheold,oryouwillfeelgreatlysorry.**************************************************结束阅读理解Eachnewschoolyearbringsfreshremindersofwhateducatorscallthesummerlearninggap.Somecallitthesummerlearningsetback.Putsimply，itmeansthelongerkidsareoutofschool，themoretheyforget.Theonlythingthey-8-\nmightgainisweight.Recentstudiesshowthatchildrengainweightmorequicklyinthesummervacationthanwhentheyareinschool.MostAmericanschoolsfollowatraditionalninemonthcalendar.Studentsgetwinterandspringbreaksandabouttenweeksofsummervacation.Someschoolsfollowayearroundcalendar.Theyholdclassesforabouteightweeksatatime，withafewweeksoffinbetween.Butmanyexpertspointoutthatthenumberofclassdaysinayearroundschoolisgenerallythesameasinatraditionalschool.Lastyear，astudyatOhioStateUniversityreportedthatyearroundstudentsdidnotlearnanymorethanotherstudents.LeadresearcherPaulvonHippelsaid“yearroundschoolsdon’treallysolvetheproblemofthesummerlearningsetback.Theysimplyspreaditoutacrosstheyear”．Acrossthecountry，theresearchshowsthatstudentsfrompoorfamiliesfallfartherbehindoverthesummervacationthanotherstudents.Expertssaythiscanbeprevented.Theynotethatmanyschoolsandlocalgovernmentsoffertheprogramsthatcanhelp.Butcallingthem“summerschools”couldbeaproblem.ThedirectorofthesummerlearningcenteratJohnsHopkins，RonFairchild，recentlywroteaboutthisissueonhisblog.HesaidthatinAmericanculture，theideaofthesummervacationisconnectedtothebeliefsaboutfreedomandthejoysofchildhood.HesaidaresearchongroupsofdifferentparentsinChicagoandBaltimorefoundthatalmostallstronglydislikedthetermsummerschool.Theysaiditcreatedanimageofchildrenbeingforcedtodoworktheymissedduringtheschoolyear.36．Whichofthefollowingistheresultofthelongsummervacation?A．Kidsbecomemuchstronger.B．Morekidsdropoutofschool.C．Kidsbecomepoorinlearning.D．Kidstakepartinallkindsofactivities.37．SomeAmericanschoolshavetheirvacations________.A．everytwomonthsB．everyfewweeksC．everythreemonthsD．everyfourmonths38．ThestudyatOhioStateUniversitysuggeststhat________.-8-\nA．thetraditionalcalendarisbetterthantheyearroundoneB．theyearroundcalendarisbetterthanthetraditionaloneC．thetraditionalcalendarisasbadastheyearroundoneD．theyearroundcalendaristhesameasthetraditionalone39．Thesummervacationismostlikelytohaveabadeffectonthekids________.A．whoaretooyoungB．whosefamiliesarepoorC．whoaretoonaughtyD．whodon’tworkhard40．AccordingtoAmericancultureduringthesummervacationkids________.A．shouldtrytheirbesttoimprovetheirlessonsB．mustchoosetotakepartinoneoftheprogramsC．shoulddowhattheylikeandenjoythemselvesD．mustbeforcedtomakeupfortheirpoorlessons36.C37.A38.D39.B40.C-8-
