dtodivorce.他们已经决定离婚，这并不令人吃惊。ItisregrettablethatTomshouldleavesosoon.真遗憾汤姆这么快就要离开了。(2)It＋be＋n.(ornounphrase)＋thatclause.Itisagreatpleasurethatsheiswellagainandcangotoheroffice.她身体恢复了，可以去上班了，这真让人高兴。Itisapitythatsheshouldrefusetoacceptthissuggestion.真遗憾她拒绝了这个建议。(3)It＋be＋v.－ed＋thatclause.ItissaidthatIsaacwillaccompanyhisparentstovisitEurope.据说艾莎克将陪父母去欧洲访问。ItissuggestedthateachchildrenshouldsingasonginEnglishattheparty.建议每个学生都得在晚会上唱支英文歌。(4)Itseems/happens...＋thatclause.Itseemsthattheyareinurgentneedofhelp.好像他们现在急需帮助。Ithappensthattheprettiestbirdsaretheworstsingers.很碰巧，最漂亮的鸟是最差的歌手。要注意的是这种结构与强调结构的区别。试比较：ItwasTonythatmanagedtohelpherintime.是托尼及时设法帮助了她。ItwasthenthatClairerealizedthatTonyhadopenedthecurtainsofthefrontwindow.也就在这时候，克莱尔才意识到托尼早就把前边窗户的窗帘拉开了。5．SoClaireborrowedapileofbooksfromthelibraryforhimtoread，orrather，scan.于是，克莱尔从图书馆借了一堆书给托尼阅读，或者说给他浏览一下。(1)apileof/pilesof＝alotof[来源:学科网ZXXK]Therewereapileofmagazinesonthedesk.桌子上有一堆杂志。I'vegotpilesofworktodothisevening.今天晚上我有一大堆工作要做。(2)orrather：awayofcorrectingsomethingyouhavesaid，ormakingitmoreexact.HelivesinLondon，orrather，inthesuburbsofLondon.他住在伦敦，更准确地说是在伦敦郊区。Youhavetobesixteenforcheaptickets—orratherundersixteen.你得是16岁才能买便宜的票，更准确地说是16岁以下。6．...youcannothavewomenfallinginlovewithmachines.,……总不能让女人爱上机器。这句话的结构是have＋n.＋doing，have的意思是causesb.todo，它与have＋sb.＋do结构的意思有时略有不同，前者讲的是过程，后者叙述的是当时的情况。AssoonasIgotthere，ItriedtohaveJohnfindmeahouse.我一到那里，就试着让约翰给我找房子。Shehadusalllaughingatherjokes.她的笑话让我们大笑。另外，在have＋n.＋doing结构中，如果have用作否定时，其意思是notpermitorallow。Ican'thaveyougoingeverywhereanddoingnothingallday.我不能让你整天无所事事地东游西逛。7．Asimovhadbothanextraordinaryimaginationthatgavehimtheabilitytoexplorefutureworldsandanamazingmindwithwhichhesearchedforexplanationsofeverything，inthepresentandthepast.阿西默夫不仅有超凡的想象力，使他能对未来世界进行探索，而且还有着惊人的智力，使他对现在的和过去的各种事物作出解释。这个句子稍微有点复杂，现简要地分析一下：Asimovhadbothanextraordinaryimaginationandanamazingmind是这个句子的重要部分，动词不定式toexplorefutureworlds修饰ability，withwhich引导的定语从句修饰anamazingmind。withwhich是“介词＋which(whom)”的结构，其介词的选择受到一定的限制：或与前面的名词搭配有关(本句就是这样)，或与后面的动词或者词组搭配有关。Heseemedtobelookingforthewordswithwhichhecouldexpresswhathewasthinkingabout.他好像正在找能表达他想法的词语。Thecar，forwhichIpaidalotofmoney，isnowoutofdate.我花很多钱买的这辆小汽车现在过时了。二、文化背景知识RobotArobotcanbedefinedasaprogrammable，self－controlleddeviceconsistingofelectronic，electrical，ormechanicalunits.Moregenerally，itisamachinethatfunctionsinplaceofalivingagent.Robotsareespeciallydesirableforcertainworkfunctionsbecause，unlikehumans，theynevergettired；theycanendurephysicalconditionsthatareuncomfortableorevendangerous；theycanoperateinairlessconditions；theydonotgetboredbyrepetition；andtheycannotbedistractedfromthetaskathand.Theconceptofrobotsisaveryoldoneyettheactualword“robot”wasinventedinthe20thcenturyfromtheCzechoslovakianwordrobotorroboticmeaningslave，servant，orforcedlabor.Robotsdon'thavetolookoractlikehumansbuttheydoneedtobeflexiblesotheycanperformdifferenttasks.,Earlyindustrialrobotshandledradioactivematerialinatomiclabsandwerecalledmaster/slavemanipulators.Theywereconnectedtogetherwithmechanicallinkagesandsteelcables.Remotearmmanipulatorscannowbemovedbypushbuttons，switchesorjoysticks.Currentrobotshaveadvancedsensorysystemsthatprocessinformationandappeartofunctionasiftheyhavebrains.Their“brain”isactuallyaformofcomputerizedartificialintelligence(AI)．AIallowsarobottoperceiveconditionsanddecideuponacourseofactionbasedonthoseconditions.Arobotcanincludeanyofthefollowingcomponents：effectors—“arms”，“legs”，“hands”，“feet”sensors—partsthatactlikesensesandcandetectobjectsorthingslikeheatandlightandconverttheobjectinformationintosymbolsthatcomputersunderstandcomputer—thebrainthatcontainsinstructionscalledalgorithmstocontroltherobotequipment—thisincludestoolsandmechanicalfixturesCharacteristicsthatmakerobotsdifferentfromregularmachineryarethatrobotsusuallyfunctionbythemselves，aresensitivetotheirenvironment，adapttovariationsintheenvironmentortoerrorsinpriorperformance，aretask－orientedandoftenhavetheabilitytotrydifferentmethodstoaccomplishatask.RobotTimeline270BCanancientGreekengineernamedCtesibusmadeorgansandwaterclockswithmovablefigures.1818—MaryShelleywrote“Frankenstein”whichwasaboutafrighteningartificiallifeformcreatedbyDr.Frankenstein.1921—Theterm“robot”wasfirstusedinaplaycalled“R.U.R.”or“Rossum'sUniversalRobots”bytheCzechwriterKarelCapek.Theplotwassimple：manmakesrobotthenrobotkillsman!1941—SciencefictionwriterIsaacAsimovfirstusedtheword“robotics”todescribethetechnologyofrobotsandpredictedtheriseofapowerfulrobotindustry.1942—Asimovwrote“Runaround”，astoryaboutrobotswhichcontainedthe“ThreeLawsofRobotics”：Arobotmaynotinjureahuman，or，throughinaction，allowahumanbeingtocometoharm.ArobotmustobeytheordersbyhumanbeingsexceptwheresuchorderswouldconflictwiththeFirstLaw.ArobotmustprotectitsownexistenceaslongassuchprotectiondoesnotconflictwiththeFirstorSecondLaw.1948—“Cybernetics”，aninfluenceonartificialintelligenceresearchwaspublishedbyNorbertWiener.1956—GeorgeDevolandJosephEngelbergerformedtheworld'sfirstrobotcompany.1959—Computer－assistedmanufacturingwasd
