Part III: Reading Comprehension

Questions 41 to 45 are based on the following passage.

It would be a fairly accurate statement to say that, when I was in elementary school and high school, I was a painfully shy child. I usually kept to myself, had only a few friends, and rarely spoke in class. My parents were always very busy, so they never pushed me to become more involved in activities and meet more people. I was perfectly happy by myself. I spent much of my time with my nose buried in a book.

The only times that I ventured away from the comforts of my bedroom were when I explored the seemingly endless aisles of stocked bookshelves at my favourite bookstore.

In retrospect, it was no surprise that I read with such an

incredible appetite. Reading was my escape. My favourite books were adventure and travel stories—stories that brought the readers to exotic, unexplored, or dangerous places. These were places I longed to go, and they were adventures I yearned to experience, but I knew it was all just a fantasy. I had a hard time working up the nerve to talk to a fellow classmate, I knew there was no way I could travel around the world and live out one of these adventures. Therefore, I read. I read every book I could find that promised adventure, excitement, or escape. By the time I graduated from high school, I had probably read more books than our school had in its library. It was quite an achievement, but no one knew about it except for me. I told no one because I had no one to tell. My only friend was Justin, and that relationship only existed because we

had been next-door neighbours for fifteen years.

Like most of my classmates, I applied to college and eventually worked up the courage to go. It wasn't easy. I had lived at home with my parents my whole life, and I rarely ever thought about leaving. However, it had finally become inevitable; I couldn't stay with them forever. I attended a local college and moved out to live in a dormitory with a roommate. It would be an understatement to say that I was nervous. I was terrified.

My roommate's name was Greg, and the first few weeks of school were very awkward. He kept trying to start conversations and be friendly. I was able to answer his questions, of course, but I found it difficult to keep the conversation going. I just wasn't used to it—I had no practice at this sort of thing. Then one day I returned from an afternoon class and found him reading a Jack London book. Suddenly, I found that I had a hundred questions to ask Greg. Did he like Jack London? Which was his favourite book? Did he read a lot? What other authors did he like? The list was endless.

To my surprise, Greg was also in love with adventure and travel books. One of his dreams was to travel around the world and follow in the footsteps of some of history's greatest explorers. There must have been magic at work that day. It was as if my shyness suddenly disappeared. Greg and I talked for hours about our favourite books and dreams of travel. I also found it easier to talk to other people at school and make friends since that day. I felt like the world opened up to me. So many things suddenly seemed possible. In fact, Greg and I are planning a great adventure for this summer! It may have taken me a while, but I finally found a way

to break out of my shell and start enjoying life.

41. Which of the following is a rite of passage that helped the

writer to become less shy?

A. Attending high school.

B. Reading many books.

C. Attending college.

D. Planning a great adventure.

42. In which paragraph does the author compare his desire to read to hunger?

A. Paragraph 1.

B. Paragraph 2.

C. Paragraph 4.

D. Paragraph 5.

43. Which of the following would make the best title for this passage?

A. A Painfully Shy Child

B. My College Life

C. Travels with Greg

D. Breaking Out of My Shell

44. "It would be an understatement to say that I was nervous. I was terrified." What does the writer

mean by this statement?

A. He wasn't nervous at all.

B. He was mildly nervous.

C. He was as nervous as usual.

D. He was extraordinarily nervous.

45. Which of the following statements can you infer from the passage?

A. Jack London wrote exciting stories.

B. Jack London wrote dull stories.

C. Jack London wasn't a famous writer.

D. Jack London was the writer's favourite writer.

第三章作业参考答案 3-03 网络适配器的作用是什么？网络适配器工作在哪一层？ 答：网络适配器功能主要包括：对数据进行串/并传输转换；对数据进行缓存；实现以太网协议；过滤功能；同时能够实现帧的传送和接收，对帧进行封装等。 网络适配器工作在物理层和数据链路层。 3-04 数据链路层的三个基本问题（帧定界、透明传输和差错检测）为什么都必须加以解决？ 答：封装成帧就是在一段数据的前后分别添加首部和尾部（在首部和尾部里面有许多必要的控制信息）构成一个帧。接收端能从收到的比特流中准确地区分出一个帧的开始和结束在什么地方； 透明传输使得不管所传数据是什么样的比特组合，都必须能够正确通过数据链路层，具体说就是解决二进制比特流中出现与帧定界符相同的位流问题； 差错检测可以检测出有差错的帧，并将其丢弃掉，从而降低了数据传输的比特差错率。 3-07 要发送的数据为1101011011。采用CRC的生成多项式是P(x)=x4+x+1 。试求应添加在数据后面的余数。 数据在传输过程中最后一个1变成了0，问接收端能否发现？ 若数据在传输过程中最后两个1都变成了0，问接收端能否发现？ 采用CRC检验后，数据链路层的传输是否变成了可靠的传输？ 答：（1）因为P(x)=x4+x+1，所以p=10011。n比p少一位，所以n=4 采用CRC校验时，被除数是：11010110110000，除数是：10011，得余数1110。 即添加数据后面的余数（帧检验序列）是1110。 （2）若数据在传输过程中最后一个1变成了0，即11010110101110除以10011，得余数为0011，不为0，接收端可以发现差错。 （3）若数据在传输过程中最后两个1都变成了0，即11010110001110除以10011，得余数为0101，不为0，接收端可以发现差错。 （4）出现以上两种情况，由于接收端均发现错误，丢弃相应的帧，而CRC校验方法没有对应的重传机制，数据链路层并不能保证接收方接到的和发送方发送的完全一致，所以，在数据链路层的传输是不可靠的。 3-14常用的局域网的网络拓扑有哪些种类？现在最流行的是哪种结构？为什么早期的以太网选择总线拓扑结构而不使用星形拓扑结构，但现在却改为使用星形拓扑结构？ 答：常用的局域网的网络拓扑有：星形网、环形网和总线网。 现在最流行的是星形网。 早期的以太网将多个计算机连接到一根总线上，当初认为这种连接方法既简单又可靠，在早期人们认为：有源器件不可靠，无源的总线结构更加可靠，所以，早期的以太网选择了总线结构。 但是实践证明，连接有大量站点的总线式以太网很容易出现故障，后期出现的集线器采用专用的ASIC芯片，一方面可以将星形结构做得非常可靠，另一方面，使用双绞线的以太网价格便宜、使用方便，因此现在的以太网一般都是用星形结构。 3-16 数据率为10Mb/s的以太网在物理媒体上的码元传输速率是多少码元/秒？ 答：码元传输速率即为波特率。 以太网使用曼彻斯特编码，这就意味着发送的每一位都有两个信号周期。标准以太网的数据速率是10Mb/s，因此波特率是数据率的两倍，即20M码元/秒。 3-20 假定1km长的CSMA/CD网络的数据率为1Gb/s。设信号在网络上的传播速率为200000km/s。求能够使用此协议的最短帧长。 答：1km长的CSMA/CD网络的单程传播时延τ=1/200000=5×10-6s，即5us，往返传播时延为2τ = 10us。 为了能够按照CSMA/CD工作，最短帧的发送时延不能小于10us。以1Gb/s速率工作，10us可以发送的比特数为：10×10-6×1×109=10000bit。 所以，最短帧长为10000bit或1250Byte。

3.Many products for sale seem to scream at us, "Buy me! Buy me!" Advertising is a big busin ess in our world with many products competing for our attention. Think of the last time you boug ht clothes. You probably noticed the variety of colors, patterns, fabrics and brands you could choo se from. Which kind of soft drink would you like to have today or what kind of computer do you want? Advertisers are skilled in the art of making their products look the best to appeal to our se nses. But products aren't always what they seem. Sometimes advertising is deceptive and as cons umers ,we must be careful about what we choose to buy. It is important to learn to compare prod ucts and identify our purpose in purchasing the things we need. But the good thing about advertising is that it helps people to make decisions and refine thei r choices. In the United States, the Ad Council creates timely public service messages to the nation. Th eir purpose is to raise awareness of public problems that citizens can respond to. Inspiring ads ca use individuals to take action and even save lives. Pollution in America, for example has been red uced over the years because of the creative Public Service advertisements that the council provid es" Please, please don't be a litter bug, 'cause every 'litter bit' hurts." Many families have taught t heir children to place litter in the trash can in response to this catchy phrase, which has affected g enerations as each succeeding generation has taught their children not to litter. 4.Nature imposes difficult conditions upon the earth from time to time . The tornado and fo rest fire destroy natural resources ,homes and other structures ,and very often harm or kill peopl e . Technological tragedies happen with little or no warning as we see trains crash and airplanes f all from the sky shortly after take-off. As tragic as calamities are , they seem to bring out the best in human nature . people trained in em ergency care arrive at the scene and begin assisting the inj ured .Others come with equipment to remove debris. Men , women ,and young people willingly c ome to the scene of an accident , hoping to be of help in some way . These selfless acts of kindne ss make our world a better place . compassion eases the wounds of calamities. American Airlines flight number 587 crashed less than three minutes after taking off from JF K Airport in New York in November,2001. Witnesses s aw an engine fire develop on the plane’s nu mber one engine located under the left wing of the aircraft .seconds later ,the airliner crashed int o eight homes ,completely destroying four of them .All 260 people aboard the airplane were kille d along with six people at the crash site ,leaving many people to mourn the loss of their loved on es .the residents (people who live in the area of the crash ) rallied together to comfort those griev ing, while others removed bodies from the wreckage and did the necessary clean-up. 工程实施困难的条件下在地上的时候。龙卷风和森林火灾破坏自然资源,房屋和其他建筑物,和经常伤害或杀死人。技术的悲剧发生在很少或没有预警,因为我们看到火车事故,飞机起飞后不久就从天空坠落。一样悲惨的灾难,他们似乎显示出人性中最好的。在急诊受训的人到达现场并开始帮助受伤的人则跟设备清除残骸。男人,女人,和年轻人自愿来到事故现场,希望能有帮助。这些无私的善举让我们的世界变得更美好。同情减轻灾害的伤口。 美国航空公司587号航班坠毁不到三分钟后从纽约肯尼迪机场起飞,11月2001。目击者看到一个引擎火灾发展在飞机上的1号引擎位于下飞机的左翼,接着后,客机坠毁八家,完全摧毁了四个260名乘客的飞机遇难连同6人在事故现场,造成许多人悼念失去的亲人,居民(住在崩溃的面积)聚集在一起,安慰那些悲伤,而另一些人则从残骸,并把尸体移走必要的清理。 5.Success can be reached in different ways by people in different careers. Bill Gates began at age to program computers,His vision for personal computing has been central to the success of M icrosoft Corporation, the company he founded with his childhood friend in 1975 . The former CEO of General Electric, Jack Welch, is a business legend. A famous quote by Mr. Welch is,” Chang before you have to. ”He believes in leading by example and encourages his empl oyees to do their best every day. Michael Jordan s aid,”I accept failure, but I can’t accept not trying.” He is one of the best athl etes to ever play team sports. His great smile, athletic achievements, and pleasant personality ha ve made him one of the most famous athletes in the world. Michael Jordan spent a lot of time pla ying basketball as a child but in senior middle school he was taken off the team . Instead of giving up , he worked through adversity and became the greatest basketball player yet .

金融学网上作业参考答案.doc

1. 结合人民币汇率变动趋势及相关数据分析汇率的作用 解答： 目前，我国实行的是有管理的浮动汇率制度，人民币汇率由市场供求决定，中国人民银行通过市场操作维持人民币汇率的相对稳定。实践证明，实行有管理的浮动汇率制度是符合中国国情的正确选择。加入WTO以后，随着贸易和投资的变化，国际收支的变化可能会较大，同时也会面临更大的外部冲击。为此，我们将继续实行以市场供求为基础的有管理的浮动汇率制度，在保持人民币币值基本稳定的前提下，进一步完善汇率形成机制。增强本外币政策的协调，发挥汇率在平衡国际收支，抵御国际资本流动冲击方面的作用。 自2005年7月21日起，我国开始实行以市场供求为基础、参考一篮子货币进行调节、有管理的浮动汇率制度。本次汇率机制改革的主要内容包括三个方面： 一是汇率调控的方式。实行以市场供求为基础、参考一篮子货币进行调节、有管理的浮动汇率制度。人民币汇率不再盯住单一美元，而是参照一篮子货币、根据市场供求关系来进行浮动。这里的"一篮子货币"，是指按照我国对外经济发展的实际情况，选择若干种主要货币，赋予相应的权重，组成一个货币篮子。同时，根据国内外经济金融形势，以市场供求为基础，参考一篮子货币计算人民币多边汇率指数的变化，对人民币汇率进行管理和调节，维护人民币汇率在合理均衡水平上的基本稳定。篮子内的货币构成，将综合考虑在我国对外贸易、外债、外商直接投资等外经贸活动占较大比重的主要国家、地区及其货币。参考一篮子表明外币之间的汇率变化会影响人民币汇率，但参考一篮子货币不等于盯住一篮子货币，它还需要将市场供求关系作为另一重要依据，据此形成有管理的浮动汇率。这将有利于增加汇率弹性，抑制单边投机，维护多边汇。 二是中间价的确定和日浮动区间。中国人民银行于每个工作日闭市后公布当日银行间外汇市场美元等交易货币对人民币汇率的收盘价，作为下一个工作日该货币对人民币交易的中间价格。现阶段，每日银行间外汇市场美元对人民币的交易价仍在人民银行公布的美元交易中间价上下0.3%的幅度内浮动，非美元货币对人民币的交易价在人民银行公布的该货币交易中间价3%的幅度内浮动率稳定。 三是起始汇率的调整。2005年7月21日19时，美元对人民币交易价格调整为1美元兑8.11元人民币，作为次日银行间外汇市场上外汇指定银行之间交易的中间价，外汇指定银行可自此时起调整对客户的挂牌汇价。这是一次性地小幅升值2%，并不是指人民币汇率第一步调整2%，事后还会有进一步的调整。因为人民币汇率制度改革重在人民币汇率形成机制的改革，而非人民币汇率水平在数量上的增减。这一调整幅度主要是根据我国贸易顺差程度和结构调整的需要来确定的，同时也考虑了国内企业进行结构调整的适应能力。 放弃单一盯住美元，不仅表现为以后的人民币汇率制度更富弹性，而且在于发挥汇率价格的杠杆作用，以便用汇率价格机制来调节国内外市场资源流向，以便促进短期宏观经济的目的(因为，汇率如同利率一样是短期宏观调控主要手段)。人民币汇率以市场供求关系为基础，今后人民币汇率水平的变化，完全取决于实体经济的变化，取决于国内经济的发展水平，而不是理论模型的高估或低估。这也预示着人民币汇率水平可能会有向上或向下的浮动。 目前人民币的汇价趋势是不断升值，这种趋势对中国经济和世界经济都会带来深远的影响。人民币汇率升值的趋势是顺应中国经济发展的表现，它对缓解中国贸易顺差会有一定的作用。人民币升值趋势对中国的贸易不会有太大的负面影响。中国的贸易仍然会有很大的发展，只是出口商品的构造会更加高度化，出口产品的附加价值会越来越高。中国人天生会做生意，又能吃苦。另外人们应该更多的关注人民币升值对国内经济平衡、产业构造调整的作用。
