势和缺点”；downandout“被打倒在地”。7．A句意：我希望你少说多做。这样事情才能变好。根据句意可知说话人希望对方“少”说话，多工作。any修饰比较级时一般用于否定句或疑问句，因此B项不正确。此空白处需要“较少”之意，排除C和D两项。8．A考查过去分词的用法。此处abandoned意为：被放弃的。句意：一千多万美金的研究费用损失在废弃的核安全项目上。9．C句意：打开窗户，我们对面就是一座大山，高耸入云，像摩天大楼。opposite在……对面；against与我们背对，相反方向。10．B句意：大多数人通过电视目睹了我们的载人飞船在太空中翱翔，这一事件极大地激励着我们。witness当场见到，目击，符合句意。seek寻找，探索，寻求；undertake从事；glance看一下，扫视。11．D句意：他致命的错误成了被攻击的目标，因为这个错误丧失了进军世界杯16强的机会。target目标，靶，受批评的对象，符合句意。12．D句意：每年的春节晚会不仅仅给我们带来许多快乐，还造就了许多超级明星，如小沈阳。annual每年的，按年度计算的，符合句意。空格前有the，故排除A、B、C三项。13．A句意：一位女士说话像放连珠炮似的是不礼貌的，听听别人的意见也很有必要。pause暂停，中止，符合句意。standfor代表，象征，表示；predict预言，预告，预测；oppose反对，反抗，与(某人)较量。14．B考查动词词义。flee既可作及物动词，又可作不及物动词；D项的时态不对；A、C项缺少介词from。15．Cdragoneself表示“蹒跚着前进”。句意：他气喘吁吁地在大街上蹒跚前进，可能病得不轻。【语篇解读】作者利用开会之余的周末时间，进行自驾旅游观光活动。尽管他们在寻找道路方面遇到一些麻烦，但是欣赏了野外美丽的风景，心情十分愉悦。16．B根据下文Myconference可知，作者来伦敦的主要目的是参加会议。17．A根据句中duringtheweek可得出答案。18．C根据句中rentacar可得出答案。19．D作者打算利用周末时间，开车出去观光，这是一种想法。20．B根据句中afterspendingalmostayearintheUK可知，Rebecca在英国待了将近一年后回到了美国。21．A结合整个句子可知，这里是setoutfor(aplace)这一搭配。22．D这里用area指代前面提到的thesouthofWales。23．C文中提到themainmotorways和themorelocalroads两种交通道路，两者相比，themainmotorways节省时间。24．B他们选择themorelocalroads是为了欣赏路两边的风光，故用sothat。25．C结合下文可知，这里说明行动的顺序，发生在行动之初，用firstly。26．D根据前句Wegotalittlelost可知，由于迷路，他们最终走得稍远了一些。endupdoingsth.表示结果。27．B根据语境可知，他们预先打算好了路线。28．A根据句中thatwouldtakeustotheabbey可知，这里指路线。29．D根据后句Itwasaspectacularview可知，这里指他们到达那里的时间。30．C根据句中werealizedthat可推断，这里指“在那个时刻”。31．A根据后句中aboutfood可得出答案。32．C根据语境可知，他们一直在观看景色，因此把吃饭的事情忘记了。33．D根据句中hadallday和语境可推断，他们一整天就喝了点可乐，用what。34．C忙了一整天，又没有吃饭，这个时候的感觉除了饿以外，当然是累了。35．A根据后句中returnedsafelytoourhotel可知，他们返回了伦敦。36．D细节理解题。由第三段第三句可知柯氏喙鲸是通过发出信号，并等待信号返回来寻找食物。37．B细节理解题。根据最后一段可知柯氏喙鲸听力的过程为B项。38．A推理判断题。根据第一段第二句可推断喉咙对柯氏喙鲸听力很重要，故选A项。【语篇解读】本文是说明文。全文说明了光污染带来的
