老人与海鸥读后感及心得200字文/沈雨萱这几天我们学了《老人与海鸥》这篇课文令我感触很深!这篇课文讲述了老人和海鸥的深厚感情。老人每天要步行20余里到翠湖,那是海鸥经常出没的地方。每天他都去那里,不管风霜雨雪也坚持去,老人只为了给海鸥送餐,跟海鸥相伴。老人喂海鸥的时候,要撮起嘴,把饼干定很小心地放在栏杆上,退开一步,海鸥们应声而来,很快把饼干丁扫得干干净净。“我”还听见了老人对海鸥的起的名字……老人死后,海鸥们翻飞盘旋、连声鸣叫,老人与海鸥永远分不开……我知道了:老人与海鸥分不开,人与动物分不开,我觉得老人在天堂也注视着海鸥。老人和海鸥朝夕相处使海鸥通了人性。在生活中也有这样的动物,比如猫、狗,人们与猫朝夕相处,使猫一见主人回来就往主人身上扑……老人与海鸥与不分离!今天,我们学了《老人与海鸥》这篇课文。这件事主要讲了一位很普通的昆仑市民——吴庆恒,他在1985年遇到一只到昆仑过冬的红嘴鸥,他就知道他所在的那个村子便幸福了,所以,他就以每个月的退休金给海鸥买食物吃,他知道海鸥爱吃饼干,但由于它们的嘴太小了,没办法吞下整个饼干,老人想了想每天把饼干弄成丁,他每月的退休金只有What’snext?ComputerandInternetplaygamesgatherinformationdoshoppingcommunicateforhomeworklistentomusicwatchmovies……DoyouknowthefollowingthetermsaboutthecomputersandtheInternet?softwareharddiskdownloaduploadbloge-mailwebsitehomepagepasswordviruswebfanshackersurftheInternet’scometothereadingFastreadingandpickouttheitemsmentionedinthetext.1.anabacus2.acalculatingmachine3.changeofmysize4.virus5.theAnalyticalMachinemadebyCharlesBabbage6.transistor7.harddisk8.connectedbyanetwork9.chatroom10.servethehumanrace★★★★★★1.Whichtype/styledoesthetextbelongto?2.Mainidea:Thisisashorthistoryofthe__________ofthecomputer.3.WhydoesthewriterusethetitleWHOAMI?A.Description(描写)B.Naration(叙述)C.Exposition(说明)D.Argumentation(议论)Personification(拟人）thefirstperson—simple,vivid（生动）,interesting,understandable.developmentthecomputerIrefersto_____________.164218221940s1970sNowCarefulreading.Finishthetimelinebelow.The“analyticalmachine”wasmadebyCharlesBabbage.Thefirstfamilyofcomputerswasconnectedtoeachother.Thecomputerbeganasacalculatingmachine．1936Thecomputergrewrapidlybothinsizeandinbrainpower.Thecomputerhadgrownaslargeasaroom.1960sManynewapplicationshavebeenfoundforthecomputer.Computersconnectpeopleallovertheworldtogether.Nowhaveyouknownmydevelopment?Para1Para2Para3TopicsentenceSupportingdetails1.calculatingmachine……1.tube……1.communitions2.finance……CarefulreadingreadthepassageagainandcompletethechartCarefulreadingReadparagraphoneandcompletethechart.ParagraphoneTopicsentenceSupportingdetails1.OvertimeIhavebeenchangedquitealot.1.calculatingmachine2.analyticalmachine3.universalmachine4.pc5.laptopPC()analyticalmachine()calculatingmachine()laptop()universalmachine12345Changesinsize•1._______________(earlier)•2._______________(inthepast)•3.____________________(modern)notverybighugesmallerandthinnerReadparagraphtwoandcompletethechart.ParagraphtwoTopicsentenceSupportingdetailsThesechangesonlybecomepossibleasmymemoryimproved.5.worldWideWeb1.tubes2.transistors3.smallchips4.networkParagraphthreeTopicsentenceSupportingdetailsSincethe1970smanynewapplicationshavebeenfoundforme.Readparagraphthreeandcompletethechart1.communications2.finance3.trade4.robots5.mobilephones6.medicaloperations7.spacerockets8.ProvidealifeofhighqualityIwasbornasa___________machinein1642.WhenIwasyoung,Iwasgoodatsimplifyingdifficultsums.About2hundredyearshadpassedbeforeIcouldthink_________andproducequickeranswers.Atthattime,Iwascalledan___________machine.In1936,Iwasbuiltasa___________machine.Ihadtheabilityto_______anymathematicalproblem.Fromthenon,Igrewrapidlybothin_______andmemory.AfterIstoredmymemoryon__________insteadofintubes.Ibecame_______insizebut_________inintelligence.logicallysolvesizetransistorssmallercleverercalculatinganalyticaluniversalSummaryInthe1960s,Icouldbeconnectedwithothercomputersbya___________.Fromthenon,Iwasabletosharemyknowledgewithothersthroughthe________________.Afterthat,Ihadmanynew______________.Now,Iamgladtoservehumanbeingsasa________friendandapleasanthelper.networkWebapplicationsdevotedAstimewentby,Ibecameevensmaller,forIputmymemoryonaverysmall______,whichmademebecomePCandlaptop.chipWorldWideDiscussionEverycoinhastwosides,sodoestheInternet.NowdiscusstheadvantagesanddisadvantagesofthecomputerandInternetingroupsandthinkwhatweshoulddo.Homework1.Practicereadingthepassage.2.WriteashortpassageabouttheadvantagesanddisadvantagesofthecomputerandInternetandwhatweshoulddo.
