Producing money requires both artistic and technological skills. Dollar bills are made so that they are interesting to look at but very hard to copy. In total, there are sixty-five separate steps required to make a dollar bill．

The money making process begins when a yearly order is sent by the Federal Reserve Board. That order will then be divided in half. Half will be done here in Washington, D.C. and the other half will be done in Fort Worth, Texas. Next, the Bureau orders special paper which is actually cloth since it is 75% cotton and 25% linen．

This paper is made so that it can last a long time. And, it is made with details that make it hard to copy. For example, bills contain security threads. These narrow pieces of plastic are inside the paper and run along the width of the bill. This special paper is also made with very small blue and red fibers．

Once the money is printed, guillotine cutters (切纸机) separate the sheets into two notes, then into individual notes．The notes are organized in "bricks," each of which contains forty one-hundred-note packages. The bricks then go to one of twelve Federal Reserve Districts, which then give the money to local banks. Ninety-five percent of the bills printed each year are used to replace money that is in circulation, or that has already been removed from circulation．

You may know that America's first president, George Washington, is pictured on the one- dollar bill. But do you know whose face is on the two, five, ten, twenty, fifty and one hundred-dollar bills? They are, in order. President Thomas Jefferson, President Abraham Lincoln, Treasury Secretary Alexander Hamilton, President Andrew Jackson, President Ulysses Grant and statesman Benjamin Franklin．

The average life span of a one-dollar bill is twenty-one months. But a ten-dollar bill lasts only about eighteen months．The one hundred-dollar bill lasts the longest, eighty-nine months．One popular question is about the two-dollar bill. This bill is not printed very often. This is because many Americans believe two-dollar bills are lucky, so they keep them．

Have you heard about Leap year?  Leap year is a year that has 366 days instead of the usual 365. It normally occurs every four years，always on an even-numbered year．The extra day is added to our shortest month. That is the second month of the year, which in non-leap years has 28 days, two fewer than any other month．    1

We also call Leap year the bissextile year．   2    In our calendar system there is a need for a leap year because the so1ar year (the time it takes the earth to go around the sun once)is actually slightly more than 365 days long. That extra day—Feb 29 every four years—helps correct the difference between our calendar and the solar calendar．

It is said that Leap year was first made part of the calendar by the ancient Roman leader Julius Caesar. His astronomers had calculated the length of the solar year to be 365 days and six hours．So Caesar declared that an extra day be added to the calendar．   3  However，Caesar’s adjustment was not completely accurate because his astronomers’year exceeded the true solar year by eleven minutes and fourteen seconds. By 1582, a difference of ten days had developed between the calendar year and the true solar year. To correct this error，Pope Gregory X III ruled that every fourth year would continue to be a leap year except for century years that could not be divided evenly by 400. By this system，century years such as 1700，1800，and 1900 were not leap years，but the year 2000 was a leap year．  4

C．This is its formal, or scientific title.

D．This may seem complicated, but it works．

E.  In a leap year, the extra day is added to the second month, giving it 29 instead of the usual 28 days．

F.  The leap year was introduced in the Julian calendar in 46 BC.

G．This is done every four years.

It was reported today that in China, 56% of people who write blogs(博客) do so as a personal diary and 83% use their blogs for sending messages to friends. It was also found that there is a strong East- West difference. In places like the US, blogs that offer information on news attract more readers but in China, blogs are more likely to be about sharing personal feelings.

It seems that bloggers can be divided into three types: IT(信息技术) bloggers, bloggers who record their ordinary feelings and media（媒体） bloggers.

When blogging first started, the IT people had the technological advantage and they took the chance to put their thoughts on the web. Some of these IT people now have had over a million people read their blogs.

The next wave of bloggers did not have any training as writers or in IT and wrote about normal daily life. Media bloggers, however, are trained writers, such as journalists and editors. When the many media bloggers showed up, the everyday bloggers lost most of their readers. Media bloggers have the advantage of knowing how to communicate well through the written words.

However, the normal bloggers are still out there and increasing in number. It seems that blogging is the new way to express your feelings. People feel like the world is listening to, or rather reading, their problems, even if they are not.

1. From the passage we know that________.

A.56% of the Chinese write blogs

B. people in US like to read blogs for news

C. the Chinese share feelings with each other mainly through blogs

D. the way that Chinese use blogs is not different from the West

2. ________wrote more blogs at the very beginning and now have more readers than others.

A.IT bloggers    B. Media bloggers    C. Normal bloggers   D. US bloggers

3. Which of the following is true according to the passage?

A. There will be more and more normal bloggers.

B. Only bloggers express their feelings through the Internet.

C. All people in the world are listening to the bloggers’ voice.

D. Media bloggers have more readers because of their popularity.

4.The underlined expression in the passage can be best replaced by “________”.

A. increased.      B. appeared .        C. arrived.          D. grew.

I am sure that everybody in his／her life has used computers．Nowadays you can feel their presence everywhere—at home，at school，at work and they certainly make life easier．On the other hand，there are people who can work without them．

    Anyway, I believe their presence is a good thing．Life with them seems less difficult and more comfortable．You can use them to choose your meal，to withdraw your money，and also to save your time，because these operations are all controlled by computers．Therefore，you can hardly imagine the modern world without them；the whole planet seems to be one big computer society．

    Nevertheless，problems can often appear in this area，too．To have a computer means you have to be quite rich and have the necessary skills to use it．However, think about questions like，“Are computers available for everyone, for rich and poor people，for people from villages and people from cities? Aren’t they too expensive? Is everyone able to learn how to use them and does everyone have the chance to access and work with them? How could everything in the future be dependent on them?” Therefore，I think our society will be divided into two parts．One part will work with them and enjoy the benefits that computers can bring and the other part will be pushed out of society and will actually be left far behind the other group．

      Another question that bothers me is，computers are important and they’re good things in our life, but they aren’t everything. They are good as a help at school, quite often as entertainment, especially for young people, as an necessary tool to help in research etc. , but I think we shouldn’t be so dependent on them, because computers are only machines and machines can’t feel anything, can’t be human and sympathetic, and every action performed by computer can be interfered(干涉) with could cause these machines to crash or work badly.

       In conclusion, I would like to say I am not against computers. I use computers too, but people should be wary all the time.

Which of the following best shows the structure of the passage?

    ①=Paragraph  ②=Paragraph2  ③=Paragraph 3  ④Paragraph4  ⑤=Paragraph5

    A．be strongly for the use of computers because of its convenience

    B．be careful with computers that will also cause problems

    C．master more necessary computer skills

    D．not do something that causes computers to work badly

In the third paragraph，the author presents his idea by       ．

      A．asking questions for people to think about

      B．giving examples to support his argument

      C．raising questions and answering them

      D．expressing his opinion directly

The author’s main purpose in writing the passage is to        ．

      A．encourage us to use computers in our society

      B．advise us to say no to computers from now on

       C．remind us to care about the problems that computers bring

      D．inform us that computers has become a necessary part of our life

Deep in the Amazon forest, thousands of people still live in isolation from the rest of the world.

In a recent press release, the Brazilian government confirmed the existence of another isolated tribe of about 200 people living in the Vale do Javari reservation. The 200 people living in the Vale do Javari reservation. The reservation, located near the Peruvian border, is about the size of Portugal. At least another 14 isolated tribes, with a total population of about 2000, call the area home.

The newly observed group lives on four large straw-roofed buildings and grows corn, peanut and other crops.

Brazil’s National Indian Foundation (BNTF) first noticed the reservation in the forest using satellite maps, but it wasn’t until April that an airplane expedition was able to confirm the tribe’s existence. “The work of finding and protecting isolated groups is part of Brazilian public policy,” said the BNIF officer for Vale do Javari, Fabricio Amorim. “To confirm something like this takes years of hard work.”

BNIF estimates there are 68 isolated tribes living in the Amazon. The organization uses airplanes to avoid disturbing the tribes through personal contact, but that doesn’t mean others are so respectful of their right to privacy.

Illegal fishing, woodcutting and hunting bring people into the protected area. Oil exploration on the Peruvian side of the border is another threat. All kinds of criminals also invade the lands of the local groups, said Amorim. The outsiders can damage the land and influence the cultures of indigenous(土著的)peoples. They can also bring diseases which can wipe out the whole population that still lack even basic antibiotics(抗生素).

Brazil’s indigenous peoples won the legal right to their traditional lands in Brazil’s 1988 Constitution, which stated that all indigenous lands shall be divided and turned over to tribes within five years. Indigenous groups now control 11 percent of Brazil’s territory, including 22 percent of the Amazon.

Allowing indigenous groups the right homelands is not just a matter of human rights. The rest of the world can benefit from their knowledge. Mark Plotkin has spent years living with the people of the Amazon and learning from their traditional healers. In his lecture, he pointed out that many useful materials and knowledge, including numerous drugs, can be gained from listening to the indigenous groups of the Amazon. Besides this, they are also more effective at protecting the land, and less expensive, than hired rangers(护林人).

1.The underlined word in the first paragraph probably means “a state of            ”.

2.From the passage we can learn that the tribes in the Amazon forest             .

3.Which of the following is TRUE according to Amorim?

4.The last paragraph is mainly about              .
