Some animals can easily find their way home after a long journey.How do they make it？Scientific research shows that they are born with certain unusual abilities for direction. A certain kind of ants，for example，can count their steps to avoid getting lost.They can go as far as 110 metres and bring food home.These ants live in the open desert（沙漠），so they have nothing to guide them along the way.It's like someone walking six kilometres through a dark forest. Some fish have an unbelievable sense of smell.They can smell even a single drop of their home water in a large sea area.Some sea birds have a similar ability.They are able to make a smell map of their flying area. Some animals can sense the earth's magnetic field （磁场），while humans can't.This magnetic field guides a certain kind of fish when they swim a long way to a place and then back.How can this kind of fish do that？It is still a mystery.Scientists have no good answers yet. However，animals with such unusual abilities still have difficulty dealing with environmental changes caused by human activities.For example，many birds depend on stars for direction，but they get lost easily at night when city lights are kept on all night.To solve this problem，we can simply turn off some lights at night.Clearly，one small act of humans may mean a lot to animals.（1）Where is this passage most probably from？ ____ A．A storybook.B．An art magazine.C．A guidebook.D．A science magazine.（2）How can a certain kind of ants find their way？ ____ A．By imagining the way.B．By counting their steps.C．By bringing food together.D．By walking through a forest.（3）What does the underlined word "mystery" in paragraph 4 probably mean？ ____ A．Secret.B．Choice.C．Reason.D．Feeling.（4）What are people advised to do according to the last paragraph？ ____ A．To help animals.B．To travel at night.C．To keep city lights on.D．To develop unusual abilities.（5）Which can be the best title for the passage？ ____ A．Birds' Sense of LightB．Fish's Sense of SmellC．Animals' Sense of DirectionD．Animals' Sense of Magnetic Field

题目解答
答案
（1）推理判断题。本文是围绕"动物的方向感"展开，可以在科学杂志上看到。故选D。
（2）细节理解题。根据第二段"A certain kind of ants，for example，can count their steps to avoid getting lost."（例如，有一种蚂蚁可以计算步数以避免迷路。）可知一些蚂蚁可以通过数步数来避免迷路。故选B。
（3）词义猜测题。根据第四段"It is still a mystery.Scientists have no good answers yet."（这仍然是个......。科学家们还没有很好的答案。）可知科学家还没有答案，因此可推知划线部分"mystery"与A选项"秘密"意思相近。故选A。
（4）细节理解题。根据最后一段"However，animals with such unusual abilities still have difficulty dealing with environmental changes caused by human activities.For example，many birds depend on stars for direction，but they get lost easily at night when city lights are kept on all night.To solve this problem，we can simply turn off some lights at night.Clearly，one small act of humans may mean a lot to animals."（然而，拥有这种不寻常能力的动物仍然难以应对人类活动造成的环境变化。例如，许多鸟类依靠星星来确定方向，但它们在夜晚很容易迷路，因为城市的灯整夜亮着。为了解决这个问题，我们可以简单地在晚上关灯。显然，人类的一个小举动对动物来说可能意味着很多。）可知本段说明人类的一个小举动可能对动物意义重大，因此是建议人们要帮助动物。故选A。
（5）标题归纳题。本文介绍了动物天生就具有某些不寻常的方向感，"动物的方向感"为最佳标题。故填C。
