Watch out, Yahoo. There is a search engine out there with super speed and accuracy. It’s very cool.
Google is the Web’s largest search engine. In just two years it has gained a reputation for surprising speed and accuracy, delivering what you are looking for in a second. The site now does this 40 million times a day --- a number achieved without spending a penny on a TV or newspaper ad.
Google doesn’t need them. In the past six months alone, the site has won a Webby (the online version of the Oscar) for technical excellence, set a new record for search engines by indexing a billion Web pages.
Yahoo still has ten times the audience, but Google consistently ranks first in customer satisfaction: 97% of users find what they are looking for most or all of the time. “You see people smile when they use it, like they’ve found something no one else knows about,” says Danny Sullivan, editor of an online newsletter.
No one is smiling more than Larry Page, 27, and Sergey Brin, 26, who seem certain to become billionaires when the company goes public, probably sometime in 2004. they make a great comedy duo(成对的表演者)。When they first met as Ph. D. students, the pair say, they found each other horrible – “I still find him horrible,” adds Brin – but driven together by a computer-science project aimed at coming up with better ways of searching the Web.
The idea behind the Google is that traditional search engines are stupid. They think relevance (关联) is based on repetition; if you type in a request for Tiger Woods, say, you’ll get websites listed according to how many times those words appear. Not only is this no guarantee of quality, but it’s also open to abuse. If you own a Tiger fan site and want to lead more people to it, simply type his name thousands of times in the site’s source code(编码).
1What does the underlined word “them” in the third paragraph refer to?
A. 40 million times              B. Speed and accuracy. 
C. TV and newspaper ads.        D. Web pages
2. Which of the following win greater customer satisfaction?
A. Yahoo        B. Tiger Woods      C. Larry Page     D. Google
3. It can be inferred that Page and Brin ______________.
A. hold very important positions in Google
B. are two ordinary computer programmers of Google.
C. used to hate each other very much
D. hold quite different opinions of computer-science
4. We can learn from the last paragraph that ___________.
A. Google is open to abuse
B. Google remains a traditional search engine
C. Google thinks relevance is based on repetition
D Google is better than traditional search engines

News that Microsoft was making a $44.6 billion bid to buy Yahoo was greeted with heated discussion by many Internet users on Friday. Here are some responses:
Mark Galeassi of Kansas City, Missouri
This is the best move for both parties. Yahoo has the ideas and Microsoft has the money to finally market these ideas correctly. Microsoft and Yahoo are a perfect fit and the deal will be good for consumers.
Scott G of New Jersey
I was a Yahoo user for years along with Hotmail from Microsoft. Then Google came along: Google Earth, Google Toolbar and Gmail. Google is so innovative (创新的) with everything they do. Yahoo and Microsoft... same old story... I don’t think the merger (合并) will do anything for either company except improve the Yahoo shareholders’ bank accounts.
Michael Glosser of Estero, Florida
Right now, Yahoo offers a lot of features and tools at no cost for all different levels of Internet users. Microsoft seeks nothing but profit. Undoubtedly, they’ll do nothing other than find ways to start removing Yahoo’s formerly non-priced features. Microsoft’s greed will ruin the great thing that Yahoo currently is.
Toni Suarez of Hacienda Heights, California
Perhaps it would bring better high technology innovations to e-mail and help in researching and developing a better Internet!
Antonio Simmons of Parkville, Maryland
Microsoft purchasing Yahoo would be nothing more than an attempt from Microsoft to further impose upon the users their poor-quality software and obtain more wealth for the company. In my opinion, they will never be able to compete with Google because Yahoo and Microsoft’s current search engines are too inferior (差的) to compete. Even if combined, they still lack.

Mr William Shakespeare and the Internet
Explanation of Contents
This is the fourth edition of these pages. It is hard to believe, but once again they are new and improved. My motive in publishing these pages remains to help and stimulate others in Shakespeare studies, and especially those who might contribute their work to the Internet. The spirit of altruism (利他主义) that originally built the Internet is not quite gone, though, sadly, through the pressure of time and profit has lessened.
A major new addition to the pages is a Shakespeare Timeline, which is an online biography mounted at this site. The problems with searching for Shakespeare resources using the available Search Engines are:
---- It is difficult to focus most searches so that you get a manageable number of relevant hits;
---- It is impossible by simply reading an abstract to make any distinction between the output of a Junior High School student and that of a professional researcher.
Another change in these pages over previous editions is the “What’s News” page.  If you come away from these pages with the feeling that they are very useful but slightly pedantic (学究的), I will have realized my goal.
An Apology
I am continually apologizing to the many who have written me requesting revisions of the pages. We are all too busy. I simply have not had the time to dedicate to these pages that I wish. But I love the material and so have, at long last, made some time to update them.
A Reminder to Young Students
These pages contain the best links I can find to Shakespeare on the Internet. As a reminder, I would say I very much enjoy hearing from people who view and use these pages. If you want to do Shakespeare research using the web, this page is a great starting point, and I keep it as current as I can. The web is in its infancy in bringing good, scholarly content to students. Don’t forget the best, if not quickest, resources are still in your library.
57. The passage is written to ____.
A. introduce the fourth edition of these pages
B. make an apology to readers
C. show off these pages to readers
D. let Shakespeare researchers buy these pages
58. Which of the following is the new addition to the pages?
A. The writer’s apology.     
B. Search Engines.
C. A Shakespeare Timeline.
D. Receiving readers’ e-mails.
59. When searching for Shakespeare resources using Search Engines, you ____.
A. will waste some time in finding what you want
B. can easily recognize what the abstract means
C. will often come into the “What’s News” pages
D. will find something special on your computers
60. Which of the following can best conclude the last paragraph?
A. The writer will often read letters from those who use these pages.
B. The writer of the passage is very selfish.
C. The web was just created four years ago.
D. Shakespeare researchers should first of all refer to these pages.

回答问题(共3小题;每小题2分,满分6分)

阅读下面短文,根据第57至第60小题的具体要求,尽可能简要回答问题,并将答案转写到答题卡上。

Before a new type of plane goes into service, every part of it is tested again and again. But there are two tests that are more important than all the others.

The first is called the “tank test”. A modern plane must fly very high in the sky. Air must be pumped into the plane so that the passengers can breathe. To test whether the plane is strong enough, it is put into a huge tank of water. If the plane can accept the pressure in the water tank, it proves that it is strong enough. If the plane is not strong enough, there will be an explosion(爆炸)in the water. Engineers can discover which part of the plane has broken. Then that part should be made stronger.

The most dangerous test happens when the new plane is going through flight tests in the air. In the test, the pilot must find out exactly what happens when the engines are all shut off at once. The plane begins to fall like a stone. It is the pilot’s job to find out how he can get control of the plane again.

These two tests are examples of how planes are made before they ever carry passengers.

58. How many kinds of tests of a new-type plane are introduced in the text? (回答词数不超过2个)

_______________________________________________________________________________

59. Where is the “tank test” carried out? (回答词数不超过7个)

_______________________________________________________________________________

60. When does the most dangerous new plane test happen? (回答词数不超过13个)

_______________________________________________________________________________
