    Artificial(假的) flowers are used for scientific as well as for decorative purposes. They are made from a variety of materials, such as wax and glass, so skillfully that they can scarcely be distinguished from natural flowers. In making such models, painstaking and artistry are called for, as well as thorough knowledge of plant structure. The collection of glass flowers in the Botanical Museum of Harvard University is the most famous in North America and is widely known throughout the scientific world. In all, there are several thousand models in colored glass, the work of two artist-naturalists, Leopold Blaschka and his son Rudolph.?
    The intention was to have the collection represent at least one member of each flower family native to the United States. Although it was never completed. It contains more than seven hundred species representing 164 families of flowering plants, a group of fruits showing the effect of fungus diseases, and thousands of flower parts and magnified details. Every detail of these is accurately reproduced in color and structure. The models are kept in locked cases as they are too valuable and fragile for classroom use.?

    1. 1.

      Which of the following is the best title for the passage??

      1. A.
        An Extensive Collection of Glass Flowers ?
      2. B.
        The Lives of Leopold and Rudolph?
      3. C.
        Flowers Native to the United States?
      4. D.
        Material Used for Artificial Flowers?

      It can be inferred from the passage that the goal of Leopold and Rudolph was to _______.?

      1. A.
        create a botanical garden where only exotic flowers grew?
      2. B.
        do a thorough study of plant structure?
      3. C.
        make a copy of one member of each United States flower family?
      4. D.
        show that glass are more realistic than wax flowers?
    3. 3.

      The underlined word “it” refers to _______.?

      1. A.
        the intention
      2. B.
        the collection ?
      3. C.
        one member
      4. D.
        each flower family?
    ACB
    1.短文说明了美国the Botanical Museum of Harvard University收藏玻璃花的目的、收藏品的丰富、精致的细节等内容,所以用An Extensive ?Collection? of Glass Flowers作标题最合适。?
    2.　根据第二段的“The intention was to have the collection represent at least one member of each flower family native to the United States.”可知收藏的目的是把美国所有的花都复制一种。
    3.　根据它前后的内容:目的是使收藏能代表美国的每一类花,尽管还没有完成,只能是收藏还没有完成。?

    To what degree can a computer achieve intelligence (智力)? The answer to this question may lie in a newly-developed US computer program called Smarter Child and the Internet．

    If you ran into Smarter Child online , you would be surprised at this kid’s huge memory．It can recite many facts． For example , Smarter Child knows every baseball player in every team this season．

    He knows every word in the dictionary and the weather in every major city areas across the US．However , if you ask Smarter Child other questions , you get stranger answers．A question about Smarter Child’s age returns． “One year, 11 days, 16 hours, 7 minutes, and 47 seconds!” Asking where he lives gets , “In a clean room in a high-tech building in California．”

    Smarter Child uses the vast information on the World Wide Web as his memory bank．To answer questions about spelling , for instance , Smarter Child goes to American Heritage Dictionary online．For the weather , he visits www．intellicast．com．

    Some scientists believe that by joining the many systems of the Internet , an artificial being with the combined knowledge of , say , Albert Einstein, Richard Nixon and Britney Spears could be born．However if Smarter Child wants to think and learn on his own like the boy-computer David in the movie A．I．, Artificial Intelligence , he must overcome two problems．

    The first is that computers find it difficult to read web pages because the files are labeled in different ways．That’s why programmers need to tell Smarter Child where to look for the weather．It would be a much more difficult task to let him find it himself．

    Another problem is that while Smarter Child can process (处理) information more exactly and faster than any human , he lacks common sense—a basic grounding of knowledge that is obvious to any young child．

    67．From the text we can infer that www．intellicast．com is a website___________．

             A．which is specially designed to help Smarter Child

             B．where we people can find Smarter Child

             C．where weather forecasts are made

             D．which is about artificial intelligence

    68．It is probably most difficult for Smarter Child to_______．

             A．tell us how to spell a difficult word

             B．tell us how the American government is run

             C．provide us with a famous poem by Shakespeare

             D．learn how to tell right behaviors from wrong ones。

    69．Which of the following is TRUE according to the text?

             A．Smart Child has his own memory bank big enough for all kinds of information．

             B．A．I．Artificial Intelligence is probably the name of a film about a boy-computer．

             C．Smart Child can recognize different files and find information needed on his own．

             D．We have similar product now which has the knowledge of Einstein , Nixon and Spears．

    70．Which of the following is the best title for the passage?

             A．A New Web Child          B．Smarter Child

             C．The Future of Internet      D．Intelligence Development

    Remembering names is an important social skill. Here are some ways to master it.

    Recite and repeat in conversation

    When you hear a person’s name, repeat it. Immediately say it to yourself several times without moving your lips. You should also repeat the name in a way that does not sound forced or artificial.

    Ask the other person to recite and repeat

       You can let other people help you remember their names. After you’ve been introduced to someone, ask that person to spell the name and pronounce it correctly for you. Most people will be pleased by the effort you’re making to learn their names.

       Admit you don’t know

       Admitting that you can’t remember someone’s name can actually make people relaxed. Most of them will feel sympathy if you say, “I’m working to remember names better. Yours is right on the tip of my tongue. What is it again?”

       Use associations.(联想)

       Link each person you meet with one thing you find interesting or unusual. For example, you could make a mental note: “Vicki Cheng-tall, black hair.” To reinforce(加强) your associations, write them on a small card as soon as possible.

       Limit the number of new names you learn at one time

       When meeting a group of people, concentrate on remembering just two or three names. Free yourself from remembering every one. Few of the people in mass introductions expect you to remember their names. Another way is to limit yourself to learning just first names. Last names can come later.

       Go early

       Consider going early to conferences, parties and classes. Sometimes just a few people show up on time. That’s fewer names for you to remember. And as more people arrive, you can hear them being introduced to others—an automatic review for you.

    1.Most people will feel ______ when you try hard to remember their names.

       A. moved         B. annoyed       C. delighted     D. discouraged

    2.If you can’t remember someone’s name, you may ____________.

    A. tell him the truth        B. tell him a white lie

    C. ask him for pity         D. ask others to help you                

    3. When you meet a group of people, it is better to remember ________.

    A all their names          B. a couple of names first

    C. just their last names     D. as many names as possible

    4.What does the text mainly tell us?

    A. Tips on an important social skill.  B. Importance of attending parties.

    C. How to make use of associations.  D. How to recite and repeat names

    四、阅读理解（共15小题；每小题2分，满分30分）

    Another man-made wonder of the United States was built long before the nation was established. About 900 years ago, the Ancestral Puebloan people built villages high in the walls of canyons in Colorado, where 600 cliff dwellings are now part of the Mesa Verde National Park.     

    Visitors can stand at the top of the mesas and look into the dwellings almost hidden in openings of the rock walls. The Puebloan people cut small steps into the rock, which connected buildings containing hundreds of rooms.

    The rock walls have protected the buildings from severe weather in the area; therefore, they remain mostly unchanged in the hundreds of years since they were built.

    Our final man-made wonder is in the northwestern city of Seattle, Washington. The Space Needle was built as the central structure for the 1962 World's Fair.           

    The 184-meter-tall structure was designed by Edward Carlson, which has a wide base on the ground, with its middle narrow and a large ring-like structure on top. The structure was meant to look like a "flying saucer," a vehicle that was popular in science fiction space travel stories.  The saucer includes an observation area and eating place. The restaurant slowly turns to provide visitors with a 360 degree view of Seattle.

    The Space Needle, only costing about $4,500,000, was not very costly, and was designed and completed in about a year and opened on the first day of the World's Fair.

    Today, the Space Needle is the most popular place for visitors to Seattle. And it remains the internationally known symbol of the city.

    56.What the passage before this one can be about?

    A.Some natural wonders in the world.

    B.Sightseeing in the US.

    C.Some other artificial wonders in the US.

    D.American geography.

    57. What does the underlined word “dwelling” mean?

             A. village                    B. house                     C. canyon                   D. step

    58. Which of the following descriptions about the Space Needle is TRUE?

             A. It is a man-made wonder in Washington, D.C..

             B. Edward Carlson built the structure.

             C. It has a ring-like structure on top.

             D. It remains the internationally known symbol of the US.

    59. What is the passage mainly about?

             A. Visiting the US                        B. Man-made wonders in the US

             C. Wonders in the world           D. Famous places in the US
