D
  Build the highway and watch the town grow.At first a few shops appear and maybe a restaurant.Then a hotel opens. Eventually new house are built. A village is born.
  This is also how the virtual world has developed. Think of the Internet as the road carrying information between two computers.Think of the World Wide Web as the village. At first it is just a place on the virtual road where travelers meet. More travelers come bringing new kinds of information. New travelers come bringing new kinds of information.New villages are started.
  Every willage has a founder.Tim Berners-Lee is the man who wrote the software programme that led to the foundation of the Word Wide Web.How did he get the idea? He tells us on his own web site. "One of the things computers were not able to do was store in formation from different sources. The dream behind the Web is of a common space in which we communicate by sharing information."
  In 1991 his programmmes were placed on to the Internet.Everyone was welcome to use them.
  Tim Berners-Lee could have followed the Microsoft route by forming a company to sell the programmes he invented. Or he could have joined another company. But in his view the Web is a language,not a pproduct. Charging a gee for using his programmes would have slowed the growth of the Web.And other companies would make similar products to compete. Instead of one World Wide Web there would be several smaller Webs. Each would use incompatible (不相容的) software. They Web is valuable because it uses a common computer language to reach people and share information. Competing webs would lose this value.Imagine if somebody sent you a bill every time you spoke a world of English.
  In 1994 Tim Berners-Lee formed the World Wide Web Consortium,or W3C.More than 200 leading companies and laboratories are represented by W3C. Together they make sure that everyone, no matter what their equipment or solftware,can work equally on the Web.
  "The Web can help people to understand the way that others live and love. It helps us understand the humanity of people," he says.
  68.The writer's purpose in writing the first two paragraphs is to ______.
   A.give us some idea of the Internet
   B.give us some idea of the Web
   C.tell us how the idea of Web started
   D.tell us the idea of the Web is wonderful
  69.Tim Berners-Lee invented the World Wide Web in order to _____
   A.place his programmers on the Internet
   B.stop smaller webs appearing
   C.help people to form a web site
   D.let people share all kinds of information
  70.According to the text,the disadvantage of competing webs is that they would ______.
   A.slow the development of the Web
   B.destroy the whole web system
   C.lose the value of information
   D.waste a lot of money

第二部分閱讀理解
Can you imagine a classroom which misses the one thing that’s long been considered a necessary part to reading and writing? Paper. No notebooks, no textbooks, no test paper. Nor are there any pencils or pens, which always seem to use up ink at the critical(關鍵的) moment.
Such a “paperless classroom” is one that more and more schools are trying to get.  
Students never do any handwriting in the class. Instead, they use specially-designed computers. The teacher downloads texts from Internet libraries and sends them to every student’s personal computer.  
Having computers also means that students can use the Internet. They can look up information on any subject they’re studying, from maths to social science.  
A middle school teacher Judy Harrell in Florida, US, described how her class used the Web to learn about the war in Iraq in 2003.  
“We could touch every side of the country through different sites: from the forest to refuges(難民營),” she said. “Using a book that’s three or four years old is impossible.”  
And exams can go online too. At a high school in Tennessee, US, students take tests on their own computers. The teacher records the grades on the network for everyone to see and then copies them to his own electronic grade book.  
A paperless classroom is a big step towards reducing the waste of paper. High school teacher Stephanie Sorrell in Kentucky, US, said she used to give about 900 pieces of paper each week to each student.  
“Think about the money and trees we could save with the computers,” she said.  
But, with all this technology, there’s always the risk that the machines will break down. So, in case of a power failure or technical problems, paper textbooks are still widely available for these hi-tech students.
41.What does the underlined sentence “use up ink at the critical moment” in the 1st paragraph mean?
A.Pens use ink, while pencils don’t.
B.Pens get lost easily at any moment.
C.Pens may have little or no ink at the key moment.
D.Pens may not write well at the critical moment.
42.What did the middle school teacher show while using the example of her class?
A.the Web could take them everywhere.
B.the Web taught them a lot.
C.the Web is a good tool for information.
D.the Web, better than the textbooks, can give the latest information.
43.What does the phrase “break down” in the last paragraph mean?
  A.Break up.        B.Stop working.       C.Fall down.     D.Lose control.

Dear MSN,

I live in San Diego. I’m single and would like to meet people near me. Can I do this on the Internet?

Searching in San Diego

Dear Searching,

On the Internet, you could easily go looking for love in all the wrong places, but here are lots of great ways to meet singles near you.

The Web is a good place to start. MSN also has international sites for Europe, Australia and South America.

There are several California-based MSN web communities where you can meet like-minded people near you as well as city-specific chat rooms for real-time interaction (互動). Hope for some clever friends. What about a little more excitement in your online interactions? Try the “Gaming Zone!”

I also tried MSN Search, looked under the “Personal” heading and found “Relationships”. Clicked on that, then found “Ads & Personals”, by “Region” and found San Diego specific personal from there. Try it!

Also, give “IRC” (Internet Relay Chat) and “Usenet Newsgroups” a shot. Many a net romance has started and then developed in these off-the-Web communities. If you’d rather make friends F2F (face to face), the Web has some helpful dating and redating tips.

1. Searching has written this letter with the purpose of ______________.

A.getting help from MSN with his computer

B.winning the heart of a love from the web.

C.meeting single people online

D.looking for love in all the wrong places

2.According to the second letter, MSN has several advantages such as _______________.

A.shooting IRC and Usenet Newsgroups

B.giving you time and places to chat with others

C.satisfying you with whatever kind of help you want

D.supplying you with many methods to make friends

3.From the second letter we can infer that MSN treats an ordinary reader so kindly and warmly because _______________.

A.it is its duty to help those who have trouble with their computers

B.it needs to attract as many readers as possible so as to make greater benefit
