61、 leader, everyone would have chosen someone like Buzz. However, at the end of the second journey, we had a different vision. 【语篇导读】本文主要介绍了作者的两次新西兰Motu河之旅。36twice根据语境可知，此处表示两次的含义，故用副词twice在句子中作状语，与下文“on the second journey”呼应。37was led根据语境及介词by可知，此处表示被动的概念，又根据上文“last year”可知，应用一般过去时，故用一般过去时的被动语态。38dev

62、elopingspend time doing sth. 意为“花费时间做某事”，为固定用法。故此处填 developing. 39without/beyond句意：毋庸置疑地服从命令是必要的。without/beyond question意为“毫无疑问，毋庸置疑”，为固定用法。40fought句意：在激流中，我们与河水搏斗并战胜了它。根据其后的overcame可知，此处是在陈述过去发生的事情，故用一般过去时。41where句意：我们把筏子划到了巴兹想让它去的地方。where引导状语从句，在从句中作地点状语。42because/since句意：在旅程结束时，我们都很兴奋、高兴，因为我们赢了。根

63、据语境可知，前后句表示逻辑上的因果关系，前果后因，故用连词 because/since。43impossible根据上文“The guide on the second journey was very softlyspoken. ”可推知，此处表示导游说话温和，在急流的噪音下不可能听到他的声音。故填impossible。44ours句意：这位安静的导游不是我们的领袖，而是一个比我们更敏感的人。空处与“whose sensitivity”呼应，故此处用名词性物主代词作宾语。45Given句意：如果给机会选择一个领导者，每个人都会选择像巴兹这样的人。分析句子结构可知，give和句子主语every

64、one之间构成逻辑上的动宾关系，故用过去分词。第三部分写作(共两节， 满分40分)第一节(满分15分)假定你是李华，计划组织一次郊游，请给你的英国朋友Chris写封邮件邀请他参加。内容包括：1参加者；2时间、地点；3活动：登山、野餐等。注意：1写作词数应为80左右；2请按如下格式在相应位置作答。_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ One possible version：Dear Chris，How is everything going these days?

67、0s, psychologist Robert Zajonc conducted a series of experiments where he showed people nonsense words and random shapes. Afterward he asked his subjects which they preferred out of everything they had been shown. In study after study, people always chose the words and shapes they had seen the most.

68、 Their preference was for familiarity. This discovery was one of the most important findings in modern psychology. But the preference for familiarity has clear limits. People get tired of even their favorite songs and movies. On the one hand, humans seek familiarity, because it makes them feel safe.

69、 On the other hand, people love the thrill of something new. This change between familiarity and discovery affects us all the timenot just our preferences for pictures and songs, but also our preferences for ideas and even people. For that reason, the power of familiarity seems to be strongest when

70、a person isnt expecting it. The opposite is also true: A surprise seems to work best when it contains some familiarity. Nobody knows this better than Raymond Loewy, who is considered to be the “father of industrial design”He had a theory that he said could help artists sell anything to anyone. He ca

71、lled it MAYA“Most Advanced Yet Acceptable”To sell something surprising, make it familiar; and to sell something familiar, make it surprising, he said. One of Loewys final tasks was to add an element (要素)of familiarity to a truly new invention: NASAs first space station. Loewys biggest contribution t

72、o the space station was that he insisted NASA install a window with a view of the earth. Today, tens of millions of people have seen this small detail in films about astronauts. It is hard to imagine a more perfect example of MAYA: a window to a new world can also show you home. _ _ _ _ _ _ _ _ _ _

73、_ _ _ _ One possible version：Through years of research, psychologist Robert Zajonc found the relationship between familiarity and preference, which affected peoples choice (要点1)However, people are dissatisfied with familiarity, and they want the thrill, so the change is important to them(要点2)Importantly, Loewy understood the best and created MAYA, a theory helping increase sales (要点3)His design used in NASAs first space station becomes a perfect example of the theory(要点4)
