题目内容
【题目】Forest are amazing and so are the animals that live in them. We enjoy watching TV shows about bears, bats or monkeys. We know a lot about their lives: how they find food or what they do at different times of the year. But what about smaller animals that are more difficult to see or film?
Many small animals that live in forests are very important for the soil. A French scientist, Francois Xavier Joly, is studying one of them — the millipede(千足虫).
The importance of leaves
When the leaves begin to die in fall, they turn from green to yellow and fall from the trees. As they decompose on the ground, nutrients(营养物质) are returned to the soil and carbon dioxide to the air. Life in the forest needs these nutrients. Without them, plants could not grow and there would be no food for animals such as the millipede.
Food on the forest floor
Some living things, like mushrooms, break the leaves into smaller pieces and eat them. In a few months there is nothing left of them. But for mushrooms, not all trees are the same. Mushrooms prefer some types of leaves to others. This means that some leaves take much longer to be broken down than others. Sometimes it takes years. So what happens to these? This is where the millipede can help.
More on the menu
The millipede also likes leaves and it eats any type. But when it has finished, it produces waste. This waste then becomes the food of mushrooms. When mushrooms eat leaves they choose only certain types but when they eat waste, they will eat any kind. This is how the millipede turns dead leaves into food for others and helps life continue.
So next time you are walking through a forest, remember that something may be having a meal right under your feet.

【解析】文章介绍森林里的一种小生物,对森林土壤非常重要的千足虫。
【1】推理判断题。根据文章第一段的句子But what about smaller animals that are more difficult to see or film?但是那些很难被看到或者被拍到的更小动物呢?下文举了千足虫的例子,可知千足虫太小了以至于不容易被人们看到。故选C。
【2】词义猜测题。本段说到,秋天树叶变黄,从树上落下来。这里当它们在地面上decompose,营养物质回到土壤里。以及结合下文This means that some leaves take much longer to be broken down than others.可知这里decompose的意思是“Break down分解”,故选A。
【3】细节理解题。根据文章倒数第二段的内容But when it has finished, it produces waste.This waste then becomes the food of mushrooms. When mushrooms eat leaves they choose only certain types but when they eat waste, they will eat any kind.千足虫吃完树叶会产生粪便。这种粪便成为了mushrooms的食物,当mushrooms吃树叶时,它们选择特定的类型,但是当它们吃粪便时,任何种类都可以。可知文章提到mushrooms,是为了说明千足虫给mushrooms提供食物。故选B。
【4】推理判断题。根据文章第一句Forest are amazing and so are the animals that live in them.森林“amazing”,住在森林里的动物也很“amazing”。下文作者介绍了森林中很重要的小动物—千足虫,可推断,在作者看来,千足虫是很“amazing”的生物。故选D。
