36、析：applicants考查名词的复数形式。applicant为可数名词，根据thousands of可知应用复数形式。6答案与解析：to考查介词。in addition to除了之外(还有)。7答案与解析：to argue考查非谓语动词。此处作目的状语，故应用动词不定式。8答案与解析：worked考查动词的时态。此处叙述过去的动作，应用一般过去时。9答案与解析：an考查冠词。此处表示泛指，且island的读音是以元音音素开头的，故用不定冠词an。10答案与解析：most important考查最高级。根据句意可知此处表示最高级，因此填most important。关键能力提升练.阅读【语篇解
37、读】文章主要介绍了科学家为研究亚马孙雨林将如何应对将来的气候变化而对过去的雨林是如何度过冰河时期进行取样研究。1答案与解析：D细节理解题。根据文中第三段第二句“To study the past climate, scientists need to look at fossilized pollen(花粉)kept in lake mud.”可知，要研究过去的气候，科学家需要看保存在湖泥中的花粉化石。故选D。2答案与解析：B细节理解题。根据文中第三段第三句“Going back to the last ice age means drilling down into lake sedimen
38、t(沉积物)，which requires specialized equipment and heavy machinery.”可知，钻到湖泊沉积物需要专门的设备和重型机械。C选项错在light。故选B。3答案与解析：C推理判断题。本文是一篇科普文章，通常写作目的是提供信息。A选项是吸引更多人对二氧化碳的注意，和文章无关；B选项是号召人们保护雨林，此文不是强调保护雨林；D选项是警告人们远离雨林的危险，文章没有讲到雨林的危险。故选C。4答案与解析：A主旨大意题。根据第一段后两句“But if you had been there around 15,000 years ago, during
39、the last ice age, would it have been the same? For more than 30 years, scientists have been arguing about how rainforests might have reacted to the cold, dry climate of the ice ages, but till now, no one has reached a satisfying answer.”可知，人们对于雨林怎样应对气候变化一直没有满意的答案，二三段讲述的是科学家进行该研究的价值和具体实践及遇到的困难，所有这些都是
40、为了揭开原因，所以标题为“雨林的神秘”是最恰当的。B、C、D选项都仅仅是文章提到的部分信息。故选A。.七选五【语篇解读】本文是一篇说明文。作者在文中首先介绍了我们要珍惜友谊。然后作者介绍友谊对于我们意义重大的三个方面：评判、分享悲伤和失去的东西、希望。1答案与解析：C考查句意理解和上下文语境理解。后句Say one has no child even after many years of marriage and the other has many children(比如说一对(夫妇)结婚多年后没有孩子，另一对夫妇有很多孩子)以生活中的夫妇为例，只有C选项涉及到couple，It is s
41、imilar to a case of two couples.(这与两对夫妇的例子很相似。)故选C。2答案与解析：B考查句意理解和上下文语境理解。上文生活中的两对夫妇为例就是为了证明一点：我们看重我们得不到的东西，而却不关注很容易就得到的。而这一点和友谊是一样的。B选项Friendship is one such relationship.(友谊也是这种关系)。故选B。3答案与解析：E考查句意理解和上下文语境理解。后句With other people our actions and behavior are always calculated and guarded and that ta
42、kes away lots of pleasure from our life.(和其他人在一起我们的行动和行为总是被评价，这带走了我们生活中的很多乐趣)提到和其他人之间没有那么多乐趣，因此可得知E选项切题。E选项We can enjoy this freedom only with friends.(我们只有和朋友在一起才能享受这一自由。)，也就是跟朋友在一起不会互相评判，故选E。4答案与解析：G考查句意理解和上下文语境理解。本段小标题Share sorrow and lossesA friend can be depended upon to share all our problems
43、and sorrows.(分享悲伤和损失，我们可以依赖朋友分享我们所有的问题和悲伤)提到分享，故只有G选项切题。G选项This sharing may not reduce the loss but helps us unburden ourselves.(这种分享或许不能减少损失，但是可以帮助我们摆脱负担。)，故选G。5答案与解析：F考查句意理解和上下文语境理解。前句中的encouragement既是解题的关键，与答案F选项中的inspiration相照应。F选项With that inspiration, we regain confidence in ourselves.(有了这一鼓励，
44、我们就会重获信心。)故选F。.完形填空【语篇解读】世界上的许多污染问题是由大量人口涌入城市造成的。人口的迅速增长和对地球资源的不合理利用也使得自然资源濒临枯竭，人类未来的生存状况取决于人们是否能够控制人口增长速度。1答案与解析：B根据上文中的“Many of the worlds pollution problems have been caused by.”可知，人口大量涌入城市导致了污染问题。所以供应人们的需求导致了进一步的污染。lead to意为“导致”，符合语境。run across意为“不期而遇；撞见”；result from意为“产生于；由引起”；bring out意为“使显现；生
45、产；出版”。2答案与解析：B结合第二段最后一句“If the population continues to grow at.”可知，如果人口继续增加，污染也会随之变得更严重。根据语境选B项。3答案与解析：Aat. rate为固定搭配，意为“以速度”。rate意为“速度”时应与介词at连用。4答案与解析：C句意为：有些科学家把人口增长称作“人口污染”。speak of. as意为“把称作”。5答案与解析：A从上句的数字可以看出，世界人口一直在增长，所以本句表示人口数到1850年应是“达到”十亿左右。reach意为“达到”，是及物动词，可以直接加宾语。get作“达到”讲时是不及物动词，不能直接跟
46、宾语。故选A项。6答案与解析：B根据下文中的by the year 2050可知，此处讲述未来的人口状况。expect意为“预期；预料”，it is expected.意为“预计”。故选B项。7答案与解析：C根据上文内容可知，文章讲述的是世界人口问题，故选C项。8答案与解析：A从下文内容“Some of them are almost gone.”可以推断，此处指人们对资源的使用，故选A项。9答案与解析：C根据前后句内容可知，资源的枯竭是由于人们对资源的加速开采使用造成的，故选C项。10答案与解析：C上文提到人口的急剧增长带来了很多问题，由此判断如果想要解决资源问题，就要控制人口的增长，故选C
47、项。11答案与解析：D结合第一段第二句“To supply the needs of the people.”可知，要满足人类的“需求”，此处与前文相呼应。need此处为名词，意为“需求”。故选D项。12答案与解析：Apresent意为“目前的；现在的”，符合语境。13答案与解析：B根据上文内容可知，世界资源匮乏，所以不能供给更多人去利用，人类就会遭遇饥饿问题。故选B项。14答案与解析：B根据下文“Many people believe that human survival in the future _ on the answer to this question.”可知，此处讨论的是人口
48、的增长是否会以现在的速度“持续”下去。故选B项。15答案与解析：Adepend on意为“依赖”。根据前文可知，人口持续增长会导致环境污染问题，而环境污染会直接影响人类的未来，也就是说，人类未来的生存状况取决于人口增长速度的解决情况，故选A项。.语法填空【语篇解读】本文通过借用凯霍加河以前污染非常严重，经过多年的努力，艰苦的工作终于有了回报，河水变干净了的事实告诉我们：当你面对看起来不可能解决的事情时，要敢于想办法慢慢解决，不能急躁，因为很多变化都是逐渐发生的，需要很多努力，我们需要耐心一点。1答案与解析：was考查动词时态和主谓一致。根据本段第一句In 1969, the pollution
49、 was terrible along the Cuyahoga River near Cleveland, Ohio.可知本段叙述的是过去发生的事情。the Cuyahoga River near Cleveland, Ohio在过去被污染得如此地严重，所以说过去没有人能够想象到这条河被清理干净。又主语“It”为三单，故填was。2答案与解析：actually考查副词用法。本句中使用副词actually做状语修饰谓语动词caught fire，actual是形容词，不能在句中做状语，通常只做定语或者表语修饰名词。故填actually。3. 答案与解析：the考查冠词。横线后是形容词最高级mo
50、st outstanding，形容词最高级前要加the，故填the。4. 答案与解析：or考查连词。从语境可知这条河流的改变不是几天或者几个月的事情。这里是两个时间短语表示选择关系，故用or。 5答案与解析：to reduce考查固定句式。固定句式：It takes sb. sth. to do sth.某人做某事花了多少时间；句中的不定式to reduce the industrial pollution and clean the water是句子真正的主语。前面的it是形式主语。故填to reduce。6答案与解析：cleaner考查比较级。本句： the water in the ri
51、ver is _ (clean) than ever，横线后面有than，说明横线上应该使用比较级的形式。故填cleaner。7答案与解析：that/which考查定语从句。本句是一个定语从句，先行词是a habit，定语从句中使用关系代词that/which指代先行词，在句中做主语，不能省略。故填which / that。8答案与解析：amazing考查形容词。这里空格处应该用形容词，来修饰后面的名词。amazing指令人吃惊的；amazed指人感到吃惊的。本句 _ (amazed) stories中此处修饰“stories 故事”，所以要用amazing。故填amazing。9答案与解析：changes考查名词复数。横线后面是系动词are，说明横线处主语应该是一个复数形式的名词，所以用changes。故填changes。change既可以作名词也可以作动词，在此为名词。10答案与解析：patient横线前面有系动词be，说明此处应用形容词，本句是一个祈使句be patient耐心一点。patient形容词，意为“耐心的”； patience名词，意为“耐心”。故填patient。
