11．Health officials in Canada are very busy these days．They are placing chickens at fixed po ints all along their 2，500km border （边境） with the United States of America．
It's not a joke，nor have the Canadians gone mad．They are using these chickens to see if the West Nile virus （病毒） is still around．The virus infects birds，so the chickens have a chance of catching the virus and fall ill．The West Nile virus is spread among humans．It killed seven people in New York last year．
Countries around the world are realizing that it may just be possible to stop certain kinds of people from entering their land．However，it is very difficult to stop viruses traveling from one end of the earth to another．When they travel to new places，they get used to the environment very easily and sometimes start destroying the local plant and animal life．These biological polluters are called smart polluters．
These smart polluters can be carried across borders of countries unknowingly．Just as we humans are travelling across the world more often than earlier，these biological polluters have also started journey much more．They slide into airplanes through their wheels．They dig into objects that travelers may be carrying from one country to another．
There are some good examples of how these polluters work．The water hyacinth （水葫芦） of South America is blocking lakes in China and Africa．Tree snakes from Papua New Guinea are busy eating up some birds in the country of Guam，which breaks its natural balance．
That's why the customs （海关） officials in many foreign countries prevent people from bringing in a small plant，or an object made of wood that is in its natural form．The customs officials have these rules because these varieties （多样性） of plants are special to certain places．The plants have the power to spread new illnesses among native plants and animals．Biological polluters always create problems in places where they do not belong．They could be special varieties of plants，bugs or even animals．
48．Why are Canadian officials placing chickens along the border？B
A．To help clean up the border．
B．To see if the virus is still around．
C．To protect the chickens from falling ill．
D．To make sure that the birds can find food．
49．Which of the following is TRUE？C
A．People find it difficult to travel from one place to another．
B．Plants always create problems in places where they belong．
C．Biological polluters may destroy the local plant and animal life．
D．Viruses spend a long time getting used to the local environment．

12．Every morning my father buys a newspaper on his way to work．Every evening my mother looks through magazines at home．And every night，I look at the posters with photos of David Beckham and Yao Ming on my bedroom wall before I go to sleep．Can weimagine life without paper or print？
  Paper was first created about 2，000 years ago，and has been made from silk，cotton，bamboo，and since the 19th century，from wood．People learned to write words on paper to make a book．But in those days，books could only be produced one at a time by hand．As a result，they were expensive and rare．And because there weren't many hooks，few people learned to read．

    Today information canbe received online，downloaded from the Internet rather than found in books，and information can be kept on CD-ROMs or machines such as MP3 players．
      Computers are already used in classrooms，and newspapers and magazines can already be read online．So will books be replaced by computers one day？No，I don't think the Yao Ming posteron my bedroom wall will ever be replaced by a computer two metres high!
