Health officials in Canada are very busy these days. They are placing chickens at fixed points all along their 2,500 km 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.

Matt ooked at their designs and his eyes widened. “Their kites are a lot better than ours. Look! This kite looks like an airplane,and that one looks like a spaceship, but our kite is a boring diamond (菱形)!”
“What if we give it a cool-looking tail?” Allie suggested. They cheered up a little and worked together on their kite all the weekend. To make the kite look better, they added a tail with beads (珠子) and tiny mirrors.
On the day of the composition, Allie and Matt carried their kite to the starting place between the spaceship and the airplane.The rules were simple.The kite that flew the highest for the longest time won.

As he ran with the kite, he could feel the wind picking it up. He let it go and ran back to help Allie. They let out the string as far as it would go, right past the spaceship and the airplane.
