beenruined点拨句意为：我遭遇大雨，我的衣服被淋坏了。ruin表示的动作发生在gotcaught之后，故排除B、D两项。此处表示被动，所以C项正确。,11.anyhow无论如何Anyhow,youcantry.无论如何你可以试试。Idontcarewhatyousay;Imgoingtodoitanyhow.比较:somehow意为“以某种方式;不知怎么地”,12.IamnowtrulyfilledwithhappinessthatIamadevotedfriendandhelperofthehumanrace!点拨that引导同位语从句，具体说明happiness的内容。that是连词，在从句中不充当任何成分。英语中用that引导同位语从句的情况比较常见，但有时也可以用连接副(代)词how,when,where,whether等来引导同位语从句。注意：if,which不能引导同位语从句。,如：Ihadtheimpressionthatshechoseherwordswithcare.在我的印象中，她选词很小心。Iheardthenewsthatourteamhadwon.我听到了我们队获胜的消息。lhavenoideawhenhewillbeback.我不知道他什么时候回来。Hemustanswerthequestionwhetherheagreestoitornot.他必须回答他是否同意这样一个问题。,I.根据下列各句句意及所给单词的首字母或汉语提示，写出该单词的正确形式。1.ThesalesgirlaskedmeifIhadtheexacts_,sincetheshophadnochange.2.Theinventionofaircraftcausedar_inourwaysoftraveling.3.WiththedevelopmentoftheInternet,theWorldWideW_hasbecomeavaluableinformationsourceforus.,sum,revolution,Web,练习,4.A_intelligenceisthestudyofhowtomakecomputersdothingsthatpeoplecando.5.TheweathermeninBeijingareplanningtofirer_todriveawayraincloudsduringthe2008Olympics.6.Twofemaletouristswererobbedoftheirmoneyand_(可移动的)phoneswhilewalkinginthestreet,sotheyfeltveryupset.7.ThecrowdcheeredwildlyatthesightofLiuXiang,whobroketheworldrecordinthe110-meterhurdle_（比赛）.,Artificial,rockets,mobile,race,8.Theyusethe_（管子）totransportoilfromthewesttotheeast.9._（人类的）facialexpressionsdifferfromthoseofanimals.10.Wewillsoonarriveatthepointwherewecanfindalltheknowledgeofhumankindonacomputer_(网络).,tube,Human,network,II.用括号内所给词的适当形式填空。1.Tryto_(simple)yourexplanationforthestudentstohelpthemunderstandbetter.2.Ifyouwanttoknowaboutthehotel,youcancallthe_(operate)tofindouttheinformation.,simplify,operator,3.Theboyisverycleverandheshowshigh_(intelligent)instudy.4._(real)isnotthewayyouwishthingstobebutthewaytheyactuallyare.5.Bobis_(total)differentfromhisfather,whoisverytall.6.Theyagreedtoacceptmy_(apply)forjoiningtheirteam.,intelligence,Reality,totally,application,7.Hissuccessinbusinessbrought_(happy)tohisparents.8.Wewillmakea_(person)visittothestudentshome.9.Hisspeechis_(logical)organizedandsoundsgreat.10.Idisagreethattheageof_(technology)revolutionhasended.,happiness,personal,logically,technological,III.用适当的介词填空。1.Istayedawakeonenight_myselftoenjoythebeautifulmoonlight.2._timeanimalshavedevelopedmanywaystostayawayfromtheirenemies.3.Hehastakenupphotography_ahobby.4.Leaves_holesinthemaresignsthatinsectshavebeenaround.,by,Over,as,with,5._thenon,Rickgotupearlyeverydayandhewasneverlate.6.Wevelearnedmanykindsoflanguages_theWorldWideWeb.7.Twogirlsjumped_happinessonthesand.8.Astimegoes_,ourlifewillimprovegreatly.,From,through/on,with,by/on,IV.每空填一词，使该句与所给句子的意思相同。1.IalwaysdothehouseworkandIalsolookafterthe
