    asuccess成功的人或事asurprise奇异的事afailure失败的人或事apity可惜的事amust必要的事aworry令人担忧的事awonder奇迹agreathelp有帮助的人或事ayouth年轻人adanger危险的人或物abeauty美人(2)表示抽象的特性、状态、思维、行为的一次、一种、一类、一下、一顿等意思时,常可组成“a/an+抽象名词”或“a/an+形容词+抽象名词”结构。如:haveasleep睡觉 dieadeath死24\ntakeagreatinterest表现极大的兴趣takealook看 getahighopinion得到很高的评价makeanapology道歉haveagoodtime玩得高兴anart一种艺术adeliciousbreakfast(lunch,supper)可口的早餐(午餐、晚餐)[即境活用1] Sheis______success,______womanassheis.A./;/   B.a;aC./;aD.a;/答案:D解析:考查冠词。第一空填a,表示“一位成功人士”;第二空as引导让步状语从句时,句子需倒装且名词前不填冠词。2.Wehave_been_excavatinglayersofashalmostsixmetresthick,whichsuggeststhattheymighthavekeptthefireburningallwinter.我们一直在挖掘一层层的积灰,几乎有六米厚,这意味着他们可能整个冬天都在烧火。(1)句中的havebeendoing是现在完成进行时。完成进行时是现在完成时的强调形式,表示动作从过去某一时间开始,一直延续到现在,可能还要继续下去,通常与表示一段时间的状语连用,如:forhours,sincethismorning等,其构成是“have/has+been+现在分词”。Ihavebeenlookingformylostbookforthreedays,butIstillhaven’tfoundit.我已经花了三天的时间找我丢失的书,但还没有找到。【注意】现在完成进行时与现在完成时的区别:①二者都可以表示动作的延续,区别在于:前者更强调动作的延续性,可以说是后者的强调形式。Wehavebeenlivingherefortenyears.(强调还要继续住下去)Wehavelivedherefortenyears.(不知道是否已经结束)②在无时间状语的情况下,前者表示动作仍在进行,而后者则表示动作在过去已结束。Thestudentshavebeenpreparingfortheexam.(还在进行24\n)Thestudentshavepreparedfortheexam.(已经结束)(2)句中的suggest含义为“暗示,表明”,后面接从句时不用虚拟语气。Hispalefacesuggestsheisinbadhealth.他面色苍白,说明他身体不好。当suggest含义为“建议,提出”时,后面跟从句时要用虚拟语气thatsb.shoulddo。Isuggestedtohimthatweshouldhandletheproblemanotherway.我向他建议我们用另一种方式处理这个问题。Thedentistsuggestedthatshe(should)comeanotherday.牙医建议她改天再来。[即境活用2] (1)Thetwocountries______tomaintaintheirmilitaryequationformanyyears.A.triedB.wastryingC.havetriedD.havebeentrying答案:D(2)Thesuggestionthatthemayor______theprizeswasacceptedbyeveryone.A.wouldpresentB.presentC.presentsD.oughttopresent答案:B3.Abruptlyshesatdown,only_to_be_scooped_upbyherlaughing,shoutingsister,Luna.她突然坐下,结果被她又笑又嚷的妹妹鲁娜抱了起来。onlytobescoopedupbyherlaughing,shoutingsister,Luna是不定式做结果状语,多表示意料之外的结果。Hehurriedtothestationonlytofindthatthetrainhadleft.他匆匆忙忙地赶到车站,结果发现火车已经开走了。提示:-ing形式做结果状语多表示由于前边的动作自然而然地导致后边的结果。如:①Theycaneatapersonintwominutes,leavingonlybones.它们可以在两分钟之内把一个人吃光,只剩骨头。②Europeanfootballisplayedinmorethan80countries,makingitthemostpopularsport.有80多个国家踢欧式足球,这使得它成为最流行的运动。24\n[即境活用3] Thenewsreportershurriedtotheairport,only______thefilmstarshadleft.A.totellB.tobetoldC.tellingD.told答案:B解析:only+todo常做结果状语,故排除C、D两项。根据句意可知是“别人告诉记者”,thenewsreporters做主语,需用被动式。易错点拨自我完善·误区备考1.alternative/choice/selection(1)alternative一般强调在只有两种可能性或者行为方式之间进行的选择。(2)choice泛指从一组人或物中进行的自由选择,指选择,挑选,抉择。(3)selection含有从许多可供选择的人或物中择优选拔的意思。[应用1] (1)Thestoreoffersawide______offruitandvegetables.商店提供许多可供选择的水果和蔬菜。(2)Anunhappy_____________isbeforeyou.YourmotherwillneverseeyouagainifyoudonotmarryMrCollins,andIwillneverseeyouagainifyoudo.摆在你面前的是个很不幸的难题,你得自己去选择。如果你不嫁给柯林斯先生,你母亲就再也不想见你,而如果你要嫁给他,我就再也不愿见到你。choicealternative(3)Parentsshouldbecarefulintheir_____________ofthemoviestheiryoungchildrensee.家长们在为孩子们挑选电影时应小心谨慎。selection2.interrupt/disturb(1)interrupt打断(某人的)谈话;中断(某人的)行动(2)disturb①打扰(尤指正在工作的人); 妨碍(某人的睡眠)24\n②使烦恼(worry)[应用2] (1)Ifyougetupearly,trynotto_________anyoneelse.如果你起得早,尽量不要打扰别人。(2)You’dbetternot___________himwhenheisspeeking.当他在说话时你最好别打断他。(3)I’msorryto___________you,butcanItalktoyouforamoment?对不起,打扰你一下,我能跟你谈一会儿吗?disturbinterruptdisturb3.现在完成进行时[应用3]
