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

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]

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]
