    I still cannot believe that I am taking up this prize that I won it last year. I have to remind constantly I am really in AD 3008. Worried about the journey, I was unsettled for a first few days. As a result, I suffered “time lag”. This is similar with the “jet lag” you get from flying, so it seems you keep getting flashbacks from your previously time period. So I was very nervous and certain at first. However, my friend and guide, Wang Ping, was very understood and gave me some green tablets which help a lot.

Terry Herbert, 55, of Staffordshire, the UK, has used a metal detector (探测器)for the past 18 years to look for treasure. He’d never found anything especially valuable. But on July 5, he made a very important discovery, which also changed the way the British look at history. In a field near his home, Herbert found a huge number of ancient artifacts. The finding was announced on September 24.
Archaeologists(考古学家) are surprised by the size of the discovery. There are more than 1,300 pieces. The discovery is much bigger than any other from the Anglo-saxon era(盎格鲁撒克逊时代),said Roger Bland of the British Museum. Bland said some experts think treasures of this kind must have belonged to a king but they couldn’t be certain.
The artifacts are thought to date from between AD 675 and AD 725, a time that is sometimes called the Dark Ages. The time was marked by frequent fighting. The gold in the collection weighs 5 kilograms. It suggests that England at the time was richer than historians thought.
Why were the gold and silver treasures buried? Archaeologists believe it could have been to hide them from enemies, a common practice at the time.
The findings could become one of Britain’s top archaeological finds. So far, experts have looked at 1,345 pieces and there are still more to come. It may take a year to look at the whole finding.
Herbert found the treasure while he was searching in a friend’s field over five days in July. He said his discovery was more fun than winning the lottery. “This is what treasure hunters dream of, finding stuff like this. The great amount there is just unbelievable,” he said.

A、he had researched the area and was sure there was treasure there.

B、the treasure has changed people’s understanding of early English history.
C、the treasure is proving a big help to the British economy.
D、it is the find that many British treasure hunters have been hoping for years.
3、On the basis of the article, which of the following is TRUE?
A、It might take three years for scientists to look through all of the treasure.
B、Ancient English people buried treasure in the fields for future use.
C、At the time England was a more violent and religious land than historians thought.

根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。(注意:如选E涂AB;选F涂AC;选G涂AD)

  1   People use money to buy food, furniture, books, bicycles and hundreds of other things they need or want. When they work, they usually get paid in money.

Most of the money today is made of metal or paper.   2   One of the first kinds of money was shells.

Shells were not the only things used as money. In China, cloth and knives were used. In the Philippine Islands, rice was used as money for a long time. Elephant tusks, monkey tails and salt were used as money in parts of Africa.

The first metal coins were made in China. They were round and had a square hole in the centre.   3  .

Different countries have used different metals and designs for their money.   4    Sweden and Russia used copper to make their money. Later some countries began to make coins of gold and silver.

But even gold and silver were inconvenient if you had to buy something expensive. Again the Chinese thought of a way to improve money.   5   The first paper money looked more like a note from one person to another than the paper money used today.

Money has had an interesting history from the days of shell money until today.

 

A. The first coins in England were made of tin (锡).

B. But people used to use all kinds of things as money.

C. No one knows for certain when people began to use money.

D. People strung (串连) them together and carried them from place to place.

E. Money, as we know, is all made of paper.

F. They began to use paper money.

G. Today anyone will accept money in exchange for goods and services.

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
