Bird Migration候鸟迁徒

秋高气爽，北雁南飞，又到了候鸟迁徙的季节。当你抬头看见“人”字形或“一”字形的雁阵时，是否思考过它们是在跟随着谁的指引，又将要飞往何方？“鸟的迁徙是一个关于承诺的故事，一种对于回归的承诺。”著名导演雅克·贝汉在纪录片《鸟的迁徙》中如此说道。让我们在一堂科学课上走近这个伟大的“承诺”，看渺小的鸟儿如何穿越万水千山，抵达故乡，书写生命的奇迹。

One day， Mr Li gives his class a special science lesson.

“Today， we are going to learn about an amazing phenomenon（现象） called bird migration.” Then， he holds up a colorful picture of birds flying in a V-shape（“人”字形）.

The classroom is buzzing with excitement. Mr Li begins to explain， “Bird migration is when birds travel long distances（距离） from one place to another. They do this to find better weather and more food.”

Li Ming raises his hand and asks， “But how do they know where to go？” Mr Li smiles and replies（回答）， “Birds have a special sense of direction（方向感）. They use the position（位置） of the sun and stars， as well as landmarks（地标） like rivers and mountains， to guide them on their journey.”

Xiao Mei jumps in， “Do all birds migrate？” Mr Li says， “No， not all birds migrate. Some birds， like sparrows（麻雀） and pigeons（鸽子）， stay in one place all year round. But many birds， especially those that live in cold places， fly to warm places when winter comes.”

Chen Wei wonders， “How far do birds migrate？” Mr Li explains， “Birds can travel thousands of kilometers during migration. Some birds， like the Arctic terns（北極燕鸥）， fly all the way from the Arctic（北极） to Antarctica（南极洲） and back again， covering a distance of over 40，000 kilometers！ So， next time you see birds flying in a V-shape across the sky， remember that they might be going on an incredible（令人惊叹的） adventure！”

As the class ends， the students realize that even tiny creatures are able to accomplish（完成） great things！
