We all know the Internet does not run fast enough. What we often do not know is why. When a Web page is slow downloading, we usually blame the kind of computer we have, the speed of the connection or the time of day. But in fact there are other things that can figure in, and they are often hidden. Did you know that there are only 13 “root name servers” in the world, serving all 150 million people using the Internet? A root server is a computer that holds the routing information for the naming system of the Internet. It allows your computer to connect with the host computer of, for example, all the www. apple. com pages. It’s like an electronic directory. Each request for a Web page generates at least two transactions well before any real content is communicated—one from the customer to find the name server, and one from the server to confirm the information to the customer. All that back-and-forth generates huge data traffic, so there is some of your slowdown. Significantly, only three of the root name servers are outside the United States in London, StockAholm and Tokyo. This means that an awful lot of Net access generated outside the United States has to go to one of the servers there to find its way. That makes it slow for users. Of course, as with many things about the Internet, the Washington area has a particular advantage. As many as four name servers are here. One is in Hemdon at Network Solutions Inc, and one is College Park at the University of Maryland Computer Science Center. The other two are maintained by the Defense Department's Network Information Center in Vienna and the Army Resource Lab in Aberdeen, Md. But the military rotates(轮换)the servers among secret locations for security purposes. The Net is “distance insensitive”. In other words, the fact that sites are close to each other does not necessarily mean that traffic will move between them faster than between far-apart sites. Singapore and Phnom Perth, for example, are about 750 miles apart. A data trip from one to the other and back takes 1,100 milliseconds. But from Singapore to Los Angeles, which is many more times distant, the data trip is just 400 milliseconds. This has a lot to do with capacity (容量)— the fattest “pipes” of access are to the top-level Internet servers, the backbone computers of the Net, the ones that function like trunk lines, providing long-distance interconnections. If you and the computer host of the page you want to reach are both near a big pipe, signals will travel between you very quickly, even if you are very far away from each other. But even if you are close together the signal will travel slowly if you have a small connecting line.55. Which of the following is the correct description about “root name servers”？A. A root name server is a route for all the Internet's naming systems.B. A root name server is a web page connecting with all the computers.C. A root name server is a hosting computer connecting with web pages.D. A root name server will connect your computer with the hosting computer.56. According to the passage, the speed that a signal travels from one site to another is mainly influenced by ______. A. the distance between two placesB. the capacity of the Internet serverC. the sensitivities of two computersD. the distance between two web sites57. This passage mainly talks about ______.A. why it's slow going on the NetB. all the problems on the InternetC. the root name servers in the worldD. how to request a web page on the Net58. From the passage, we can infer that ______.A. people in America can get access to the Net fasterB. nowhere has more advanced root name servers than in HemdonC. most Net access has to find their ways from American name serversD. distance insensitivity is another factor that affects the signal on the Net英语答案
Research that went into developing the highly specialized technology for space travel has resulted in many unexpected practical applications back on earth. Out of the engineering that produced rocket motors, liquid propellants (推进剂), space suits, and other necessities of space flight came by-products that no one had anticipated. Equipment and procedures designed for astronauts and space flights have been successfully adapted for use in medicine, industry, and the home. These valuable products of space research, called spin-offs, have improved the quality of life on earth in many ways.Some of the best-known examples of spin-offs from space research are found in hospitals and doctors' offices. One such example is the sight switch, which was originally developed to allow astronauts to control their spacecraft without ______ their hands. The sight46.

Do You Want to Achieve Your Coals? Then Make a List! A research shows that if you want to achieve things, you need to start making lists. Many people believe that list making is only for the super-organized. In fact, making lists can be good for all of us! For one thing, making lists can help us deal with stress. If you're feeling stressed out about all of the tasks you have to do, writing them down can help you to see that there is an end in sight. Lists can also help you to become more creative, as many well- known writers and artists can tell you. This is because making lists can help you to recover memories and other things that you may have forgotten otherwise. Crossing items off a list when you have completed a task is a great feeling. If you feel anxious, try to include a couple of small tasks on your list-making your bed, for example. When you cross the item off, you will feel as if you have achieved something. Remember that lists don't always have to be to-do lists. They can also be a way of celebrating your achievements. Why not make a list of places you've traveled, of websites you like, or of the things you've managed to do-a“got done"list rather than a“to-do”list? This can remind you that although there's a lot to do, there's also a lot that you've successfully achieved. 1/5 46. According to the writer,_46_ is not just for very organized people. 请输入答案...

Reading comprehension Not long ago, when out-of-town relatives would stay with me for the weekend, my favorite part of each visit happened after the kids went to sleep. We'd pour ourselves wine and chat until nearly midnight, laughing about old memories and sharing new stories. These days, the dynamic is completely different. Everyone gathers where we used to regale each other with amusing anecdotes, but there's silence instead of laughter as everyone checks e-mail accounts, text messages and Facebook feeds. We might eventually pour some wine and talk, but everyone keeps a mobile phone in his or her lap the whole night, and the conversation is often interrupted. Whenever this happens,I yearn wistfully (渴望地) for the days when my relatives and I would focus all of our attention on each other and really connect. ... —— 1/5 1. What does the author most likely expect people to do? A Not to check the mobile phones during conversation. B Not to be addicted to mobile games. C To have higher levels of empathy than before. D To have more conversations and fewer texts.

The increase in international business and in foreign investment has created a need for executives with knowledge of foreign languages and skills in cross-cultural communication. Americans, however, have not been well trained in either area and, consequently, have not enjoyed the same level of success in negotiation in an international arena as have their foreign counterparts. Negotiating is the process of communicating back and forth for the purpose of reaching an agreement. It involves persuasion and compromise, but in order to participate in either one, the negotiators must understand the ways in which people are persuaded and how compromise is reached within the culture of the negotiation. In many international business negotiations abroad, Americans are perceived as wealthy and impersonal. It often appears to the foreign negotiator that the American represents a large multi-million-dollar corporation that can afford to pay the price without bargaining further. The American negotiator’s role becomes that of an impersonal supplier of information and cash. In studies of American negotiators abroad, several traits have been identified that may serve to confirm this stereotypical perception, while undermining the negotiator’s position. Two traits in particular that cause cross-cultural misunderstanding are directness and impatience on the part of the American negotiator. Furthermore, American negotiators often insist on realizing short-term goals. Foreign negotiators, on the other hand, may value the relationship established between negotiators and may be willing to invest time in it for long-term benefits. In order to solidify the relationship, they may opt for indirect interactions without regard for the time involved in getting to know the other negotiator. Clearly, perceptions and differences in values affect the outcomes of negotiations and the success of negotiators. For Americans to play a more effective role in international business negotiations, they must put forth more effort to improve cross-cultural understanding. [共5题](1)What kind of manager is needed in present international business and foreign investment? [本题2分]A. The man who represents a large multi-million-dollar corporation. B. The man with knowledge of foreign languages and skills in cross-cultural communication. C. The man who is wealthy and impersonal. D. The man who can negotiate with his foreign counterparts.

question or statement.Hot pot is a traditional dish in China. It is believed to date back more than 1,000 years to the time of the Jin Dynasty. Hot pot's origins can be found in the dining practices of Mongolian horsemen who rode across the steppe and into northern China. Legend has it that the Mongols used their helmets as pots to simmer (炖) broth (汤底) over open fires, and cooked chunks of meat in the broth.Hot pot cooking seems to have spread to northern China during the Tang Dynasty. In the regional variations developed with different ingredients such as seafood. In the centuries that witnessed the growth of the Song Dynasty, hot pot moved — and changed — further south, with each successive region adapting it to their local ingredients and tastes.The ingredients in a hot pot vary a lot from region to region. Perhaps the most famous hot pot is the Chongqing or Sichuan hot pot. It features a dark red broth chock-full (塞满了的) of spices, chili peppers, and the uniquely mouth-numbing Sichuan peppers. In Beijing and elsewhere in the north, hot pot broth tends to be mild and, compared to its racy southern "cousins", a little light. In the northeast of China, a kind of local sauerkraut (酸菜) is used to add some tang (强烈的味道), making the broth a bit sour. People can choose a version of hot pot according to their taste.1 Hot pot is believed to date back more than 1,000 years to the time of _______.A. the Jin Dynasty B. the Tang DynastyC. the Song Dynasty D. the Yuan Dynasty

The Harry Potter series, written by J.K. Rowling, is perhaps the most popular set of novels of the modern era. With seven books and many successful films to its name, the series has gathered about 15 billion dollars in sales. How did the series become so popular? The reason can be broken down into several areas.The first book in the series was rejected 12 times before it was picked up by Bloomsbury—a small publisher in England. So receiving this contract was Rowling's first step to success. However, getting a book contract does not ensure the success of a book. The story was soon loved by children and adults alike. In light of this, Bloomsbury Publishing published a second version of the books with “adult” (less colorful and more boring) book covers. This made it easier for a full range of ages to enjoy the series.Another factor that worked like a charm was that the publisher and Rowling herself, through the books, conducted midnight releases, promotions, and pre-ordering more readers. Customers who feared that their local bookstore would run out of copies responded by pre-ordering over 700,000 copies before the July 8, 2000 release.What does the underlined word “releases” (Para. 3) mean?A. The activity that frees or expresses energy or emotion.B. The announcement about the book’s publishing information.C. The sales of books that is available only at midnight.
