veforgottenwhatshelookslike A suchB veryC soD too 点拨 两题都考查so that 的用法 8 AndmymemorybecamesolargethatevenIcouldn tbelieveit 句型 so that 如此 以致于 与too to 句型的相互转换 Andmymemorybecametoolargeformetobelieveit egHeissooldthathecan tcarrythebox Heistoooldtocarrythebox 此结构中的that从句表示结果 Thestoneissoheavythatnoonecanliftit 比较 sothat既可以表结果 也可以表目的 9 ButIwasalwayssolonelystandingtherebymyself untilinearly1960stheygavemeafamilyconnectedbyanetwork 点拨 until表示 直到 时 在肯定句中 指从开始到结束的整段时间 谓语动词一般是延续性的 在否定句中构成not until 意为 直到 才 指到某一点动作才开始 谓语动词一般是非延续性的 其强调句是itis was notuntil that 当notuntil位于句首时 句子要进行倒装 如 Theexpertsexploredtheislanduntiltheendoflastyear 直到去年年底 专家们一直都在勘查这个小岛 Wedidn tsolvetheproblemuntilMr Smithhelpedus 直到史密斯先生帮助我们 我们才解决了那个问题 Itwasnotuntillastyearthatmyhopebecameareality Notuntilnoondiditstopraining 10 Ihavealsobeenputintorobotsandusedtomakemobilephonesaswellashelpwithmedicaloperations 1 help sb withsth协助 某人 做某事e g Amanishelpingthepolicewiththeirenquiries 有一男子在协助警方进行调查 2 aswellas也 还 而且 e g Hegrowsflowersaswellasvegetables Sheisatalentedmusicianaswellasbeingaphotographer 3 这个句子是现在完成时被动语态 其机构是 have has been 过去分词 e g Theradiohasbeenrepairedwhenwephonedtheshop 考例1 ProfessorJameswillgiveusalectureontheWesternculture butwhenandwhere yet A hasn tbeendecidedB haven tdecidedC isn tbeingdecidedD aren tdecided 点拨 本题考查动词的时态 语态及主谓一致 由yet可知要用完成时态 又因时间与地点是被决定的 故应用被动语态 此外 在什么时候和什么地点 做报告 是指同一件事 故用单数形式 考例2 Whenyougetthepaperback payspecialattentiontowhat A havemarkedB havebeenmarkedC hadmarkedD hadbeenmarked 点拨 因mark这一动作发生在get之前 且试卷是被批注 因此应用现在完成时的被动语态 11 anyhow无论如何Anyhow youcantry 无论如何你可以试试 Idon tcarewhatyousay I mgoingtodoitanyhow 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
