七年级英语下册第二单元翻译

POLLUTION FIGHTERS
Judy is collecting some facts for a class project on pollution. She is interviewing Doctor Ray, a scientist, about trees.
JUDY Why are you so interested in trees, Doctor Ray?
DR RAY They’re the biggest and oldest living things on Earth, Judy.
JUDY But what are they useful for?
DR RAY Many things. For example, the wood in your pencil, the rubber on the end of your pencil, and the paper in your notebook all come from trees. Also, do you enjoy breathing fresh air?
JUDY Of course.
DR RAY Then you must thank trees for that, too. Trees are natural air conditioners. They cool the air and clean it. Three trees can do the job of 15 air conditioners.
JUDY You know a lot about trees, Doctor.
DR RAY Not really. Scientists are only now beginning to understand them. For example, when insects attack a tree, it can warn its neighbours. The other trees then produce a chemical to make their leaves taste bad to protect themselves. Some trees can also join their roots together underground, and pass each other food and water. Trees are communicating with one another, but we don’t know how.
JUDY Are trees in danger?
DR RAY Yes, they are in great danger. We cut down and burn a lot of trees every year. We are destroying our best fighters against pollution.
