阅读理解
Snow forests make up about 30% of the world's total forest areas．These wonderful woodlands are not as famous as the Amazon rainforests but they are just as important．
Snow forests are found in the far north of the world，in areas that are quite cold and usually have a lot of snowfall．They lie across parts of Canada，China，Finland，Japan，Norway，Russia，Sweden and the US．Snow forests have very cold winters that can last up to six months．But even so，they are home to many kinds of animals，including foxes，mice and wolves．In the US and Canada，as many as five billion birds from more than 300 species live in the forests in the breeding(繁殖) season．
These woodlands perform an important job: helping to take in harmful gases．The gases are given off by burning coal，oil and gas，which can cause climate change．However，snow forests are facing several problems．Trees are being cut down faster and faster for their wood，which can be used for building．Some forests are being cleared to make space for new roads and houses，or to allow coal and gas industries to grow．What's worse，as the world gets warmer，Canada and Russia have seen terrible fires spread through the forests．
Luckily，environmental and wildlife groups around the world are working hard to protect snow forests．This means that cutting down trees is controlled in some areas and the forests are seen as areas of special scientific interest．When wood is needed，replanting plans and careful forest management help to reduce the human influence so that the forests are managed in a way that they can survive and regrow．

解析：推理判断题。根据“But even so，they are home to many kinds of animals，including foxes，mice and wolves．In the US and Canada，as many as five billion birds from more than 300 species live in the forests in the breeding (繁殖) season．”可知，雪林是多种动物的家园，300多个物种、多达50亿只的鸟类生活在森林中。由此推知，雪林对许多动物和鸟类都很重要。故选D。
(　C　)3．What mainly causes snow forests to be in danger

Dear students，
The environment is important to us．As students，what can we do to protect the environment
To reduce white pollution，we should use fewer plastic bags when going shopping． We can use cloth bags instead． We should try to reuse old textbooks． Therefore，people needn't cut down more trees to make paper． In order to save energy，we should use the lift less． We should also save water and electricity． And we should plant more trees so that the air will be fresher． Besides，we'd better go to school on foot or by bike． It is also good for our health．
I believe that we can make the world a better place to live in by working together．
