2．AVATAR director James Cameron is now taking his camera deep into the ocean．
On March 25，he did alone submarine（潜水艇）dive nearly 11 kilometers down to the deepest place in the ocean，the Mariana Trench（马里亚纳海沟）in the westem Pacific．
Compared with the colorful forest of Avatar，the Mariana Trench is dark and icy cold Cameron became the first person to explore the deepest valley in the ocean since two men made a 20-minute trip there in 1960．
"I felt like I literally（真正地）had gone to another planet and come back"Cameron told the Associated Press after returning from his dive．"It's really the sense of isolation（与世隔绝），realizing how tiny you are down in this big，black and unexplored place．"
The filmmaker has spend the past few years working with his team of engineers to design and build the submarine called Deepsea Challenger．Unlike ordinary submarines，it is wrapped（包围）in cameras and lights so that Cameron can film the ocean from the inside．
The minute-long video that Cameron took while under the sea has been released by the National Geographic．There are no words in the video，but there is something fascinating about this extremely quiet and distantplace．Cameron said be was thankful that he had had the chance to go there．
"There had be a moment where I just stopped，and took it in，and said，‘This is where I am at the bottom of the ocean，the deepest place on Earth What does that mean？'"Cameron told reporters．
The Mariana Trench was once thought to be of little interest to scientists．It was assumed that nothing could live under so much pressure and with so little light，But in recent years scientists have found creatures there like fish and shrimps （虾）that can resist the heavy pressure．They are also trying to figure out what role deep-sea trenches play in earthquakes．
Cameron told the BBC that he does not want this dive to be one-time thing．He wants to use it as a platform for further ocean exploration

分析 本文讲述了《阿凡达》导演詹姆斯．卡梅伦带着他的相机乘坐"深海挑战者"潜艇去马里亚纳海沟探险并全程拍下深海景色．
解答 41．C 写作意图题．本篇文章目的是为了告诉读者卡梅伦去马里亚纳海沟的探险．
42．C推理判断题．由第六段中的There are no words in the video，but there is something fascinating about this extremely quiet and distantplace．Cameron said be was thankful that he had had the chance to go there．可知卡梅伦他在深海所看见的事情感到惊喜．A"感到着急 被隔阂"；B"为安全担忧"；D"征服了整片海域而兴奋"均与文章不符．
43．A 理解推理题．由第五段中的Unlike ordinary submarines，it is wrapped（包围）in cameras and lights so that Cameron can film the ocean from the inside．可知"深海挑战者"与一般潜艇的区别是安装了海底拍摄装置，以供卡梅伦拍摄海底的景象．
44．B 理解推理题．由第三段卡梅伦成为了1960年两人作了20分的深海旅行之后的第一人，可知A项不对．由倒数第二段可知科学家对马里亚纳海沟不太感兴趣，它里面没有生物存在，但是近些年科学家已经发现有如虾的生物存在，还试图找出深海海沟在地震过程中所扮演的角色．故B正确，CD两项错误．
45．B 理解推理题，根据第二段 he did alone submarine（潜水艇）dive nearly 11 kilometers down to the deepest place in the ocean，the Mariana Trench（马里亚纳海沟）in the westem Pacific．他独自一人驾驶潜水艇去探险；第五段提到The filmmaker has spend the past few years working with his team of engineers to design and build the submarine called Deepsea Challenger．他和团队花了数年的时间去设计和修建 Deepsea Challenger等，可知，詹姆斯．卡梅伦是一个极富挑战精神的人，故选B．
点评 本文讲述了《阿凡达》导演詹姆斯．卡梅伦带着他的相机乘坐"深海挑战者"潜艇去马里亚纳海沟探险并全程拍下深海景色的一个故事，题目涉及多道细节理解题，做题时结合原文和题目有针对性的找出相关语句进行仔细分析，结合选项选出正确答案．推理判断题也是要在抓住关键句子的基础上合理的分析才能得出正确答案，切忌胡乱猜测，一定要做到有理有据．
