C C 　　①Forests are important to our planet.Among them， snow forests play a key role.Snow forests make up about 30％ of the world’s total forest area.These wonderful woodlands are not very famous， but they are still important.Snow forests are found in the far north of the world in areas that are quite cold and usually have a lot of snow.They lie across parts of Canada， China， Finland， Japan， Norway， Russia， Sweden and the US.Snow forests stretch(延伸) for thousands of miles and cover about 17％ of the Earth’s total land area. 　　②Snow forests have very cold winters that can last up to six months， but even so， they are the habitat of many animals.Animals that live in the snow forests include foxes， hares(野兔)， mice and wolves.In the US and Canada， as many as five billion birds of more than 300 kinds live in the forests during the breeding(繁殖) season.These huge woodlands also perform a very important job：helping to take in carbon-based gases(含碳气体)， which can cause climate change. 　　③However， snow forests are in great danger.Trees are being cut down faster and faster for buildings.Some forests are being cleared to make space for new roads and houses.This harms the home of wildlife.As the world gets warmer and the weather changes， the risk of fires in snow forests puts huge areas in danger.In recent years， Canada and Russia have seen very serious fires spreading through the forests. 　　④Luckily， environmental and wildlife groups around the world are working hard to turn snow forests into protected areas.This means that cutting down trees is controlled in some areas and the forests are seen as areas of special scientific value. 　　根据语篇内容，选择最佳选项。 (　　)56.What per cent of the world’s forest areas are covered by snow forests？ A.About 17 per cent.　　 B.About 30 per cent.　　 C.About 70 per cent. B (　　)57.What does the underlined word “habitat” in Paragraph 2 probably mean？ A.Place for making things.　　 B.Place where animals live.　　 C.Place for protecting animals. B (　　)58.细节多选题Why are snow forests in great danger？ ①People cut down too many trees.　　　　　　　 ②Serious fires break out often. ③Too many animals live there.　　　　　　　 ④People build roads and houses. A.①②③　　 B.①②④　　 C.②③④ B (　　)59.What is the writer’s main purpose of writing this passage？ A.To introduce how the snow forests grow. B.To teach us how to protect the snow forests. C.To call on people to protect the snow forests. C (　　)60.文章结构图Which of the following best shows the structure(结构) of the passage？ A.　　 B.　　 C. C D A forest is like a football team.It sounds unusual， but it’s true.Each player does an important job， but they can’t win by themselves.So they work together.The same is true of all plants and animals in a forest.They depend on each other to live.We call this an ecosystem. 　　There are three roles in an ecosystem：producer， consumer and decomposer.The trees in the forest produce food by themselves.Giraffes can’t make their own food， so they consume leaves of trees.But sometimes hungry lions or other animals may eat giraffes.When animals die， their bodies become part of the soil and this helps the forest grow.Small living things like bacteria(细菌) break down the bodies quickly， giving food back to the plants.So the ecosystem can keep on going. 　　Ecosystems come in lots of kinds and sizes.A backyard or even a big sea can be an ecosystem.The key thing is that an ecosystem has to be balanced.If there weren’t animals that eat giraffes， giraffes would eat too many leaves.This wouldn’t be good for the trees， and this would make it difficult for giraffes to find food.Different weather and natural disasters can change the ecosystems.Human activities such as cutting down trees and hunting can also bring problems.For example， if people catch too many fish in the sea， birds that eat fish may not have enough food to live. 　　Ecosystems are everywhere and they play an important role.They give us clean air， fresh water and many useful things.It is necessary for us to do what we can to keep them working well. 　　根据语篇内容，按要求回答问题。 61.How many roles are there in an ecosystem？ ______________________________________________________ Three/3.　 62.If the snake lives mainly on small animals， what role does it play in an ecosystem？ ______________________________________________________ 63.What’s the most important thing in an ecosystem？ ______________________________________________________ 64.What may cause an ecosystem to change？ ______________________________________________________ A consumer.　 An ecosystem has to be balanced.　 Different weather， natural disasters and human activities.　 65.What can we do to help the ecosystem to work well？ (不超过15个词) __________________________________________________________________________________________________________________________________________________________________ We can plant trees to provide homes for animals and clean the air./We can save resources， such as turning　off lights and taps when they are not in use./… (开放性试题，言之有理即可。)　 五、选词填空(本大题共10小题，每小题1分，共10分。)
