Above all19A.through B. acrossC. in D. over20A.help B. favorC. doubt D. treat答案与解析1A从文章的下文中可知，小男孩是抢钱包的，所以他手里拿的作案工具是“刀”。所以该题的正确答案为A项。2C从后面的Diaz对那个孩子所进行的教育可知， Diaz在心中已经“意识”到了那天晚上会有大的改变。而imagine的意思为“想象
18、”； understand的意思为“理解”； explain则为“解释”；只有realize是“意识到”的意思。故该题的正确答案为C项。3B从下文中的那个小孩拿着钱包，可以推出Diaz在此处是把钱包“递给”了他，故应该用pass，所以该题的正确答案为B项。4D从后面的Hey, wait a minute可知Diaz是在后面喊，故应该用call。故该题的正确答案为D项。5Dlose是在不知道东西具体在哪里遗失的情况下用的，而forget则是“忘记”的意思；从文章的意思来看， Diaz是提醒那个男孩是否“忘记东西”，而不是提醒他“丢掉了什么东西”。所以该题的正确答案为D项。6C被抢劫的人问抢劫犯是
19、否“忘记了什么东西”，抢劫犯当然感觉到“吃惊”，故应该用surprised。所以该题的正确答案为C项。7D从文章的第一句，我们不难发现该故事是发生在晚上，故该题的正确答案为D项。8C从文章的第一句中的snowy说明天气很冷，故Diaz要给他外套让他“保暖”。故该题的正确答案为C项。9D年轻人看着Diaz，“并且”问他为什么这样做；“看”和“问”是并列发生的动作。故该题的正确答案为D项。10B这里Diaz和那个男孩都知道抢劫犯是冒着坐监狱的危险作案的，坐监狱当然就失去“自由”，故此处应该用freedom。因此该题的正确答案为B项。11A上一句提到的“a few dollars”，很显然他是需要钱
20、了，故此处应该用money。所以该题的正确答案为A项。12C从下文中的他们在一起吃饭不难判断Diaz很“高兴”和那个青年一起吃饭。所以此处应该用happy。故该题的正确答案为C项。13D从下文中的“they headed into Diazs favourite restaurant together”可知那个年轻的抢劫犯同意接受Diaz的邀请，故此处应该用accept。所以该题的正确答案为D项。14D他们要到餐馆去吃饭，所以他们不可能坐在街道上或厨房里，故可以排除A、B两项；他们应该是坐在“餐桌”旁边，故应该用table。另外在第19题后面的“the table without thinki
21、ng”有明确的暗示。所以该题的正确答案为D项。15A根据下文中的“he was beginning to see that kindness wasnt such a strange thing”可知Diaz对餐馆里的人非常友好，所以要用kind。故该题的正确答案为A项。16B该句的意思为“我没有想到人们真的会有那样的行为举止？” behave的意思为“行为举止”，而act的意思为“表演”， listen意为“听”； appreciate是“鉴赏；感激”的意思。所以该题的正确答案为B项。17B从下文中的“hed have to get the check和and Diaz paid for t
22、he dinner”不难推知他们该付账了，因此是“账单”来了，所以要用bill。故该题的正确答案为B项。18Cas a result的意思为“结果”； in other words“换句话说”； above all“首先”； after all“毕竟”。该句的意思为：他毕竟还拿着Diaz的钱包。故该题的正确答案为C项。19Bacross指在物体的表面通过， over指从物体的上面通过， through指从立体空间内通过， in则是在里面。小孩是把钱包从桌子表面滑过去的。故该题的正确答案为B项。20D从下文中的暗示“they treat you right”不难发现该题的正确答案为D项。.阅读理
23、解Arctic ice has reformed rapidly this winter after a record summer low, but it still covers less of the Arctic Ocean than it did decades ago. March is the month where Arctic sea ice traditionally hits its highest extent after the Northern Hemisphere winter and Antarctic sea ice reaches its lowest ex
24、tent.Arctic sea ice reached a record low this past summer, with 23 percent less sea ice cover than the previous record low and 39 percent less than the average amount that has previously spanned the Arctic Ocean in the summer months.The area of ocean covered by sea ice isnt the only factor in the “h
25、ealth” of the Arctic ice. Arctic sea ice comes in two types: older, thicker perennial ice that has survived at least one summer melt season and younger, thinner seasonal ice that forms in the winter and melts again in the summer. Seasonal ice melts more easily because its thin and salty, and so its
26、easily affected by winds and currents.Colder temperatures in parts of the Arctic increased the amount of thin, seasonal ice that formed this winter. So while Arctic sea ice was dominated by perennial ice in the past decades, its mostly now younger, newlyformed ice. But because the majority of the ic
27、e is young and thin, it would be more susceptible to summer melt.Some of the seasonal ice could become perennial sea ice if summer conditions are cooler than normal. But, one cold summer isnt going to do it and one cold winter isnt going to do it. Numerous years of colder temperatures would be neede

29、ing for the time being.C. The area for the Arctic ice was increasing.D.

30、the Arctic sea ice.B. The perennial ice.C. The seasonal sea ice.D. The Antarctic sea ice.答案与解析B细节判断题。根据文章第三段，冰是由季节性的冰和永久性的冰共同组成的，但是季节性的冰容易融化而永久性的冰是长久的，所以永久性的冰的面积的多少更能够决定北极冰的健康性。故答案选B项。3According to the text, we know that the perennial sea ice _.Ais not only thick but also saltyB. mainly stays on the
31、 islands in the ArcticC. can be made out of the seasonal iceD. covers less sea in winter than in summer答案与解析C细节判断题。选项A错在salty上，具有salty的是seasonal ice；选项B the perennial sea ice应该是待在海中而不是岛上的；根据文章最后一段，选项C所说的是正确的；选项D应该是冬天的冰的面积要比夏天的多而不是少。故答案选C项。4The underlined word “susceptible” in the fourth paragraph means _.Aeasily influencedB. difficultly movedC. easily broken D. easily impressed答案与解析A词义猜测题。因为冰形成时间很短而且很薄，所以对于夏季的融化是很容易受到影响的。而另外三个选项在词义与语境的结合上不恰当。故答案选A项。
