　　【先睹为快】

　　41. G 42. D 43. E 44. B 45. C

　　【文章大意】

　　地球上曾经有过的动物中，有很多我们已无缘再见，只有通过化石我们才能对那些已消失的动物稍有了解。能够留下化石的动物一般都生活在水边，例如河、湖、海洋等。在化石中发现的最早的动物的结构都很简单，后来出现了结构较复杂的鱼类，它们长有脊椎骨，还有贝类等甲壳动物，再接着就是两栖动物和爬行动物，再后来是哺乳动物，其中一些比较后期的化石，在原始人的岩画上我们已经可以看到。

　　【答案透析】

　　41. 【答案】 G。

　　前面说人类出现之前很多动物生命形态都灭绝了，但是它们身体的骨骼等组成部分却保存在化石里。而后面则说此类岩石能告诉我们不少信息，那么可以判断中间这一部分应当也是在说明有关化石的内容，而且是我们从化石中可以获得什么内容，故可以选择出G。

　　42. 【答案】D。

　　前面说了水生动物化石的形成过程，后面说我们就会知道有很多类的哺乳动物和鸟类之类，因此中间应该继续化石形成的讨论，故可以选择D。

　　43. 【答案】 E。

　　后一句讲到了later forms are more complex，那么这必然是与前一句中所述内容进行比较，结合选项，可以判断出选项E正确，因为E中讲述了早期的一些化石。

　　44. 【答案】 B。

　　这一段在说动物的进化，鱼类——两栖动物，那么之后按照进化顺序，就应该是爬行动物，再是哺乳动物。结合选项，B最合适。

　　45. 【答案】 C。

　　接上文讲爬行动物的时代终结，之后便是哺乳动物，那么选项中讲哺乳动物的C便为正确选项。

　　Part C

　　46. In the second half of the 20th century, world output of corn, wheat and cereal crops more than tripled. Yet there is not enough to feed the rich, the aspirational and the poor in the world. A golden age has been transformed quite suddenly into a global crisis。

　　【分析】 more than在这里做副词。aspiration是指渴望，热切希望，那么句中包含在rich和poor之间，the aspirational则可以译为朝着中产阶级奋斗的人们。the poor译为穷苦的人。

　　【译文】20世纪下半叶，世界玉米、小麦以及谷物产量增长三倍多，可是仍不足以养活全世界人民，包括富人、穷人以及那些正努力朝着中产阶级奋斗的人们。黄金时代突然演变成了全球性危机。

　　47. A combination of these factors, he says, will ultimately force a complete rethinking of the way we make food。

　　【分析】主体结构是combination will force a rethinking。the way后面是一个定语从句。

　　【译文】这些因素合在一起，他说，将最终迫使我们重新思考我们的粮食生产方式。

　　48. Water was also plentiful — it takes 1,000 tonnes of water to produce a tonne of grain — and an ingenious process known as Haber-Bosch makes synthetic nitrogen fertiliser easily available to grain farmers。

　　【分析】 复合句。Water was plentiful 和 process makes fertiliser…。破折号中间的为插入语，known as 作定语修饰process，easily后面作补语。

　　【译文】水资源也比较充足——尽管生产一吨粮食就需要1000吨水——而且利用哈伯博施法的发明，使得农民们可以获得廉价的氮肥。

　　49. Eating organic product could be a partial solution, although one study suggests that the cost of avoiding intensive farm chemicals would mean a 31% increase in food prices。

　　【分析】复合句。although引导一个让步状语从句，其中that引导一个宾语从句。

　　【译文】进食有机食物或许能在一定程度上解决问题，可一项研究表明，如果要避免大量使用农业化学肥料，粮食价格将要上涨31%。

　　50. Fashionably, Mr.  Roberts believes that a local system based on easily obtainable seasonal foods that do not need to be transported huge distances would form part of a solution。

　　【分析】第一个that后面整个句子是一个宾语从句，即Mr.  Roberts believes that…，这个宾语从句的主体结构是a local system would form…，based on…为 system的定语，其中嵌套that引导的定语从句修饰seasonal foods。

　　【译文】按照普遍的观点，Roberts认为建立一种以容易获取的应季食物为基础的本地体系，以使食物不需要长距离运输，将会是解决方案的一部分。

　　Section IIIWriting

　　Part A

　　Dear John,

　　I am really happy that you can make this visit to our city. After all these years of correspondence, I cannot wait to see you, to hear your narration of your life in your city, and to discuss all those unfinished topics. However, I regret to inform you that I will not be able to meet you at the airport on time。

　　The reason is that your flight will arrive early in the morning, and the most probable time I can make to the airport will be around an hour after your scheduled landing. So would you please wait for me in the arrival lounge after you pick up your luggage? You may have a cup of coffee in the café there。

　　By the way, as we have never met I must tell you how to identify me in the crowd: I will wear a blue and white stripes polo shirt, blue jeans, and a white baseball hat. Moreover I will have a piece of China Daily at hands。

　　Hope we can meet soon。

　　Sincerely yours,

　　Roger

　　Part B

　　Groups of bees work together to produce honey. Their great efforts are unselfish, as all the honey they have produced is for an entire group rather than a single individual. The drawing above suggests that people should selflessly dedicate themselves to their community as a whole. This spirit of dedication requires faith. Selfless hard work is the embodiment of responsibility and strength。

　　The health of nations requires a spirit of devotion. Chinese teachers, doctors and athletes who all work for the benefit of their country, for example, are devoting themselves regardless of fame or fortune. They are dedicated to the society they live in. No matter what type of job one holds, one should work hard and earnestly to improve one's community。

　　The results of dedication, however, depend not only on one's willingness to give but also on one's ability. If you are enthusiastic about devoting yourself to your country, but do not have the skills it takes to do so, you cannot effect many changes. The more competent one is, the greater one's contribution will be. Therefore, it is essential that students focus on their studies and enhance their skills in order to properly give back to society。
