　　Explorer (探险者、探测器)of the Extreme Deep

　　1. Oceans cover more than two-thirds of our planet. Yet, just a small fraction(一部分) of the underwater world has been explored. Now, Scientists at the Woods Hole1 Oceanographic Institution in Massachusetts are building an underwater vehicle that will carry explorers as deep as 6,500 meters . The new machine, known as a manned submersible(潜艇;潜水器) or human-operated vehicle , will replace another one named Alvin which has an amazing record of discovery, playing a key role in various important and famous undersea expeditions. Alvin has been operating for 40 years but can go down only 4,500 meters . Its about time for an upgrade, WHOI researchers say.

　　2. Alvin was launched in 1964. Since then, Alvin has worked between 200 and 250 days a year, says Daniel Fornari, a marine geologist(地质学家)and director of the Deep Ocean Exploration Institute at WHOI. During its lifetime, Alvin has carried some 12,000 people on a total of more than 3,000 dives(潜水;跳水).

　　3. A newer, better versions of Alvin is bound to reveal even more surprises about a world that is still full of mysteries, Fornari says. It might also make the job of exploration a little easier. We take so much for granted on land, Fornari says. We can walk around and see with our eyes how big things are. We can see colors, special arrangements.

　　4.. Size-wise, the new HOV will be similar to Alvin. Itll be about 37 feet long. The setting area inside will be a small sphere, about 8 feet wide, like Alvin, itll carry a pilot and two passengers. It will be just as maneuverable(机动的，可调动的). In most other ways, it will give passengers more opportunities to enjoy the view, for one thing. Alvin has only three windows, the new vehicle will have five, with more overlap(重叠) so that the passengers and the pilot can see the same thing.

　　5. Alvin can go up and down at a rate of 30 meters every second, and its maximum speed is 2 knots , while the new vehicle will be able to ascend (上升)and descend at 44 meters per second. Itll reach speeds of 3 knots, or 3.5 miles per hour.

　　题目详解：

　　1. 首先，请大家关注这篇出现在08年教材中的新增篇目。第一个原因是因为它所涉及的内容是我们理工类比较常考的;第二是由于单词的难度也属于C级的。做阅读的老规矩还是先看文章的标题来大致了解文章的大意：Explorer (探险者、探测器)of the Extreme(极度的、极端的) Deep(深度、深处)

　　我们可以知道该文章应该讲的是和海洋探测有关的内容。人类对于海洋仍然有很多不解之谜。所以这是一篇值得我们好好学的文章。

　　接下来，一起阅读首段首句看能否了解到文章的大意：

　　Oceans(海洋) cover(覆盖) more than(超过) two-thirds(三分之二) of our planet(行星). Yet(相当于but, 表示转折关系，特别关注这种词，有可能是主题句。), just(相当于only, 仅仅) a small(小) fraction(一部分) of the underwater(合成词， under + water, 水下的) world(世界) has been explored(该词和标题中的explorer是同根词，意思是探测、探索。).

　　2. 接下来，看看所给的题，通过阅读题干我们知道它们是细节题，而细节题的主要解题顺序是文章进行的顺序。因此，我们先阅读第一题：

　　1.What is Alvin?

　　A) A research(研究) institute(协会、学院).

　　B) A transporting (运输)vehicle(车辆、工具).

　　C) A submersible(潜艇).

　　D A scientist(科学家).

　　Oceans cover more than two-thirds of our planet. Yet, just a small fraction(一部分) of the underwater world has been explored. Now, Scientists at the Woods Hole Oceanographic Institution in Massachusetts(美国的洲名) are building(修建、建造)an underwater vehicle(一个水下的工具) that(引导的是定语从句，所以后面句子的主语仍然是an underwater vehicle)will carry(携带、运送)explorers as deep as(asas像。。。一样) 6,500 meters .1. The new machine(新的机器), known as(被看作是) a manned(是man的合成词，载人的) submersible(潜艇;潜水器) or human-operated(由人来操控的) vehicle , will replace(动词，相当于take the place of, 意思是代替、替代) another one named(被称做，过去分词做定语) Alvin which(引导定语从句)has an amazing(令人吃惊的) record(记录) of discovery(探索、发现), playing a key role in(在。。。方面起者关键作用) various(各种各样的)

　　important and famous undersea expeditions(探险、考察). Alvin has been operating(运行) for 40 years but can go down(下沉) only 4,500 meters . Its about time for an upgrade(升级), WHOI researchers(研究人员们) say.

　　分析并得出结论：通过对该段第二、第三句话意思的了解，可以确定答案就是C。

　　3. 接下来，我们一起阅读第2题：

　　2.Which of the following statements is NOT a fact about Alvin?

　　(下面有关Alvin的陈述哪一个是不正确的?)

　　A) It can carry explorers as deep as 6,500 meters.(它可以将探测者带到6500米的深处。)

　　B) It has played a key role in various important undersea expeditions。(它在各种各样的海底探险方面起着关键的作用。)

　　C) It was launched in the sixties of the twentieth century. (它是在20世纪60年代被发射的。)

　　D) It has been used for more than 40 years.(它已经被使用超过40年。)

　　分析：这是一道标准的细节题，因此应该从文章中出现了Alvin的语句中找答案，并排除正确的，留下的便是我们要找的。首先，得回到第一段刚才读过的句子里看看：从第二句开始的意思是：科学家正在研制一艘可将研究人员带到6,500米深处的潜水装置，而它将替代 Alvin，因为 Alvin 只能潜到4,500米深处。还有一层意思：Alvin已经运行了40多年，而且在各种各样重要的和著名的海底探险中起着重要作用，与B，D的表述吻合，而答案A，就是一个错误的表述。但如果错误答案在最后呢，因此，我们仍需要对剩余的答案从文章里找到支持它们的语句。看第二段：

　　Alvin was launched (发射)in 1964. Since then(自从那时开始), Alvin has worked between 200 and 250 days a year(一年工作200至250天), says Daniel Fornari, a marine(海洋的) geologist(地质学家)and director of the Deep Ocean Exploration Institute at WHOI. During its(代词，指代Alvin) lifetime(一生、终生), Alvin has carried some(放在数词前面，表示大约，相当于about) 12,000 people on a total of more than 3,000 dives(潜水;跳水).

　　得出结论：第一句话就是答案C的表述。所以，最终确定答案是A。

　　4.看第三题：

　　3. a world that is still full of mysteries refers to (一个充满了神秘的世界指的是。。。)

　　A) The earth.(地球) B) Out space. (太空)

　　C) The ocean.(海洋) D) Mars.(火星)

　　细节题。请看第3段，然后根据这句话的前后文，猜出句子中单词所指。

　　A newer(更新的), better (更好的)versions (版本)of Alvin is bound to(固定词组：一定会) reveal(揭示、显示，同义词：show) even (甚至)more(更多的)surprises (惊喜)about a world that is still full of mysteries, Fornari says. It(代词，指代A newer, better versions of Alvin) might(表推测，可能) also make the job of exploration(该词是explore的名词) a little easier(轻松、容易). We take so much for granted (这是一个值得大家记住的习语，意思是认为。。。理所当然)on land(在陆地上), Fornari says. We can walk around(四处走) and see with our eyes(用我们的眼睛) how big things are. We can see colors(色彩), special arrangements(特殊的安排).

　　在回答这道题时，有一部分考生会把答案选择为A， 认为是地球，那你就错了，别忘了这篇文章的主旨是探测海底世界，而且通过我们对前面内容的学习也已经知道，Alvin就是一个海底潜水装置，因此答案只可能是C。 我在这里再一次，提醒各位：做阅读理解题目时一定要牢记文章的主题，不能选偏离主旨的答案。

　　5.看最后两题，发现题干和关键词几乎一致：都和HOV有关。

　　4. In what aspects are the new HOV and Alvin similar?(在什么方面新的HOV and Alvin是相似的)

　　A) Size尺寸. B) Speed.速度 C) Capacity.容量 D) Shape.形状

　　5. In what aspects are the new HOV and Alvin different? (在什么方面新的HOV and Alvin是不同的)

　　A) Offering better views.提供更好的风景 B) Speed.

　　C) Size. D) Both A and B.

　　扫视一下文章最后两段可以确定答案应同时在第4段，第5段中出现：

　　Size-wise(大小适中), the new HOV will be similar to(与。。。是相似的) Alvin. Itll be about 37 feet(英尺) long. The setting area(区域) inside(里面的) will be a small sphere(球体), about 8 feet wide(宽), like Alvin, itll carry a pilot(飞行员) and two passengers(乘客). It will be just as maneuverable(机动的，可调动的). In most other ways(在大多数其它方面), it will give passengers more opportunities(机会) to enjoy(欣赏) the view, for one thing. Alvin has only three windows, the new vehicle will have five, with more overlap(重叠、折叠) so that(以便于，表目的) the passengers and the pilot can see the same thing(同样的东西).

　　Alvin can go up and down at a rate(以。。。的速度) of 30 meters every second(每秒), and its maximum(最大) speed is 2 knots (节), while(而) the new vehicle will be able to ascend (上升)and descend (下降)at 44 meters per second. Itll reach speeds of 3 knots, or 3.5 miles per hour.

　　分析总结：看完这一段我们总结一下，看看相似和不同之处分别是什么：

　　第四段的头三个句子告诉我们，HOV 和 Alvin 在体积上和容量上相似。所以 D 是正确选择。

　　第四段最后两句告诉我们，Alvin 只有三个窗户，而 HOV 有五个。最后一段告诉我们，两艘潜水装置的上下活动速度和行进速度有所差别。所以 D 是正确选择。
