Oriole’s Nest

 

Picky, Picky

Scientists have no idea exactly why birds choose certain objects to build their nests. But scientists know that the main reason birds build nests is to keep their babies safe, warm and healthy.

    Baby birds grow faster and are healthier when they are warm. They also learn to fly and leave the nests sooner than birds without warm homes.

What A Yarn (紗)

Yarn is big on an oriole’s shopping list during nest building. Scientists are still trying to work out why so many birds choose white yarn over other colors for nest building.

Scientists think that the white objects remind birds of cotton fluff (絨毛) they find in the wild.

Do It Naturally  

Even though birds can help us recycle some of our junk by using it to build nests, they also need to use lots of natural things. Long grass, dried sticks, spider’s silk and mud are some of the natural ingredients that are good for nests, too.

You can make a collection box of things to leave for birds so they can help themselves. Hang a small plastic box with holes on a tree branch. Fill the box freely with nest building goodies. Hang the box on a tree and watch birds climb on board to pick through the junk to find their treasures.

Warning: Don’t let the birds turn into a tasty treat. Keep your bird station away from places where cats hang out.

For The Birds!

Stop! Don’t throw all that garbage out! Give some to the birds. Look and see how your old junk can help beautify and warm a bird’s new home.

科目：初中英語 來源：2011年北京市密云縣中考英語一模試卷 題型：閱讀理解

Farmer Ed Rawlings smiles as he looks at his orange trees. The young oranges are growing well in Florida’s weather. Warm sunshine and gentle rains, along with Ed Rawlings’ expert care, will produce a good crop（收成）of oranges this year.

However, Ed has to guard against Florida’s changeable winter weather. In January and February, temperatures can destroy Ed’s entire orange crop. Having farmed in Florida for the past 35 years, Ed is prepared for the frost(霜). When temperatures drop below freezing, Ed tries to save his crop by watering his orange trees. The water freezes and forms a thin layer(層) of ice around the trees. Strange as it may sound, this thin layer of ice actually keeps the fruit warm.

What happens is simple. When the trees are watered, the water loses heat and becomes ice. The warmth of the heat it loses is taken in by the fruit and keeps its temperature at a safe level. Ed has effectively used this method to save many orange crops.

But Ed still faces difficulties. The trees must be watered at the exact moment the temperature drops to the freezing point. Also, just the right quantity(數(shù)量)of water must be used. Too much water can form a thicker layer of ice that will break the tree’s branches(樹枝). Another difficulty is that wind blows away the heat, so Ed has to worry about not only when but also how often his trees should be watered, and how much water should be used.

Computer technology may help Ed with some of these worries. With equipment(設(shè)備), air and soil temperatures and wind speed can be measured. The information is fed into a computer which can calculate(計(jì)算) when the temperature will drop below freezing. The computer can correctly decide the quantity of water to be used and how frequently(  ) the trees should be watered. Ed finds looking after his orange trees a lot easier with the help of a computer, and, his customers will have the benefits(利益) of computer—age oranges. 

1.The passage is mainly about______.

A. a farmer expert cares for his orange trees

B. the different uses of computers

C. growing oranges in Florida’s changeable weather

D. different ways of frost protection

2.Ed tries to protect his crop by______.

    A. using a wind machine to drive away the cold air

    B. equipping his orange trees with a computer

    C. watering it at the proper time

    D. picking his fruit at the first sign of frost

3. According to the passage, the computer technology______.

    A. removes the need for frost protection

    B. prevents temperature from dropping

    C. tells farmers why outdoor temperatures change

    D. helps the farmer get a better harvest
