datefrom表示“从开始，始于时间

,追溯到”。Bappealtosb。对有吸引力，句意：设计应该雅俗共赏，老少皆宜。appear看起来忧如是；suit,fit是及物动词，不与to连用。Doffer与provide的用法分别为：offer后跟双宾语，即:offersb。sth.;provide要用以下形式：providesb.withsth.和providesth。forsb。。29。Cprovide常用于explaintosb.sth或explainsth.tosb.结构.30。Beventually最后,终于；typically典型地,典型的做法是；particularly特别地；especially特别地；特别地；句意：典型的做法是，他会来晚尔后说对不起.31。Aattach（to）附加,系上，附上，attack侵袭，攻击；attract吸引；attribute把归功于，是由于.32.Ashow后要跟双宾语，即showsb.sth.；把忘在哪儿要用学必求其心得，业必贵于专精“forgetsth+。介词+地点。”D。观察冠词.beindangerof为固定短语，意为“有危险的"。D。观察非谓语动词.此处应用不定式的主动形式表示被动意义。35。C。观察短语动词。holdoutfor意为“坚持要"。C.观察时态。依照语境可知,Alice过去打篮球和网球，但现在已放弃，故此空用一般过去时。37。D.观察动词短语。dieaway表示“（风、声音等）渐息，渐弱”。38。D。观察非谓语动词.过去分词短语作原因状语，相当于原因状语从句Becausehewasleftinthecareofhisgrandmother。39。C.观察交际用语。thatdepends表示“视情况而定”。A。观察名词性从句。第一空用what引导主语从句；第二空用where引导宾语从句。完形填空36。C依照后文可知,天正“下着雨".37。A余者不及signing含义正确。38.DA、B不能够接sth.todo,C接sth.todo时作“认为”讲，在此不合语境。39。C打车的人自然希望过往的出租车能“停”下来。40.A依照语境可消除B、C、D（thought）接从句时，一般作“认为”讲,不合文意。41。D全句意思为：我若是不曾有乘“出租车”这一念想该多好啊！car表意不正确，它除了指出租车外，还可指其他车子。42.B“脱下”帽子以便倒掉积水.学必求其心得，业必贵于专精43.B将水从帽边倒“出”。44。A从第十九个空格后的withoutunderstandingwhatthedriverhadsaidtome中可判断出.45。D告诉司机的应是所去的地方，即“地点”。余者不合习惯表示法。46.B从他不再向住处区送客来看，他已“下”班。47.Cpickup系固定搭配,意为“搭载”。48.D依照习惯表达法选定。49.A“到这时为止”雨下得更大了。50.C鸣喇叭来督促的车子必然是“在后边”。51.B鸣喇叭是“要求”前面的车子启动.余者不合语境。52。A依照从句谓语的虚假语气形式选定.53.C从词的用法角度考虑。54.C我知道在未理解司机话的情况下，我“不该”上车。55。B从句表示的是退步关系。阅读理解56.B（细节理解题。从第一段第二、三行能够找到答案）.57.C（鉴识正误题。依照第三段的“Nearly00015plant，speciesarenativetoYunnanProvince”能够判断C项错误,而其他三项的表述都可从文中找出凭据证明它们是正确的，所以答案是

C项.）58.A（细节理解题。从末段的第二、三行能够得知答案

.）D（看法态度题.末段第一行表示了作者对旅游业的看法是兼顾利与弊，这才是最客观的看法,所以正确答案是D项。)学必求其心得，业必贵于专精C从第一段第一句话能够看出，哈雷的发现是在研究其他科学家的观察中得出的，其他选项与本文内容不符。61。B第一确定彗星下次出现的时间是1758年，尔后确定这一事件距离他展望的时间是53年,再用1758减去53年就可以得出正确答案。62。D通读全文，就可以看出全文的马虎,文章的每一段都在介绍哈雷及他的发现，别的也能够从文章的首尾句看出本文的主旨马虎。63.C本文第一句话说哈雷是一个英国科学家,故A项是错误的;从第二句能够看出，哈雷的发现是在研究其他科学家观察的基础上得出的,所以B项是错误的；从第二段最后一句可得知哈雷彗星的轨道是椭圆形的，所以消除D项。此题题材还可以够依照自己的知识来选出项为正确答案。B(文章第一句话“Millionsofyearsagodinosaurslivedontheearth。”可知恐龙生活于几百万年前.)65.D（文章第一段介绍恐龙灭绝的一个原
