26、词原形”，should可省略；也可用urge sb. to do sth.。由于urge后跟宾格her，故排除A、D。答案为C。5A考查固定短语。be well aware of “对非常清楚”；be well worth “非常值得”；be content with “对满意”；be satisfied with “对满意”。句意为：当尤塞恩博尔特准备在伦敦奥运会卫冕的时候，他很清楚他将为观众带来什么。因此答案为A。6A考查副词辨析。narrowly “勉强地，以毫厘之差”； slightly “稍微地”，强调程度；nearly “接近，几乎”； lightly “轻轻地；轻松地；容易地；不
27、费力地”。本句意为：令他们欣慰的是，他们的学生刚好勉强从摇晃的大楼中逃脱。7B考查形容词词义辨析。句意：任何和小孩待过的人都知道男孩和女孩应对相似情况的方式是不同的。be aware of 意识到。8A考查副词辨析。句意为：喜欢听好音乐是一回事，自己能演奏好又完全是另外一回事。A项表示“完全”；B项very一般用在形容词、副词、限定词前面，也可表示“正是”；C项rather表示“相当，很”，可用于形容词、副词、比较级、限定词以及too等的前面；D项much表示“很多”，可修饰比较级。根据句意及用法选择A项。9C考查短语辨析。in the meantime “同时，在期间”。句意：你去买水果，同
28、时我来做早餐。at all time “无论何时”，on other hand “另一方面”，均不符合题意。10C考查非谓语动词。cant help doing sth.禁不住/情不自禁做某事，不符合题意；cant help do/to do sth.不能帮助做某事。11B考查宾语从句。句意：确保门关上了，且所有的灯都关上了之后，那个男孩打开门进了他的卧室。checked后跟了两个宾语从句，第一个从句的引导词that省略了。12D考查交际用语。当别人赞赏你的时候，应该从礼貌的角度表示感谢。13A考查句子结构及look forward to 的基本用法。本句主语是the foreign frie
29、nds，you referred to是定语从句，所以谓语动词使用are，构成现在进行时；短语look forward to中的to是介词，用动名词形式作其宾语。14B考查scare的用法。句意：在街道的拐角处，一些青年人威胁小学生交出钱来。scare sb.into doing sth.“威胁某人做某事”。15C考查副词用法。句意：当妈妈回顾他们婚姻初期时，她不知道他们是如何在如此少的金钱的情况下顺利度过那些日子的。当名词前有few，little(少), many 或much修饰时用副词so，而不用such，又因为money为不可数名词，故选C。.A研究表明，噪声污染对海洋生物带来了危险，科

32、B判断推理题。由文章的最后一句话They want to prevent noises from harming creatures in the ocean.可知，科学家将来要采取措施阻止噪音对海洋生物的伤害。B自古以来，海底丰富的资源一直吸引着人类。然而，从事深水潜水探索，却不是一件轻松的工作。本文向我们介绍的就是深水潜水员所面临的困难和挑战。20B主旨大意题。由文章结构可以看出，文章首先点明了海洋对人类的重大意义，然后提出了文章要说明的主题：To explore deep water, man faces even more dangers and problems.下文围绕这一主题作了
33、详细的说明。21A细节理解题。由第三段的最后一句(under great pressure)以及前文的叙述可知。22C细节理解题。由最后一段的If the diver rises too quicklyThe diver is then suffering from the bends.可知，潜水员得减压病(the bends)的原因是在海水中上升得太快。23B推理判断题。从文章内容可以知道，在深海潜水时，人会面临更大的危险和更多的麻烦(more dangers and problems)，包括呼吸、高压造成的不适，甚至会得减压病。由此可以判断：人在深海是很不舒适的。解答此题的关键是准确理解选
