种子迁徙
大家都知道，开花的植物不能飞、跑、或步行。但是，通过种子，它们可以“迁徙”到各处。这就是为什么你每年都会见到新的植物在之前没有的地方长出来。开花植物有许多不同的颜色，大小各异，但它们都有种子。植物保存种子的部分被称为果实。有些种子被包在果实里，随之传播。其他的则掉下来，被带走，在适合的地方发芽生长。但是，它们如何来到这些新地方呢？一些种子粘到人的衣服或动物的皮毛上，从而被带往别处，那些掉下来的种子会就地萌发成新的植物，其它种子可随著风雨散落各处。无论传播的方式是什么，种子肯定能迁徙。

Traveling Seeds
Everyone knows that flowering plants cannot fly, run, or walk. But, through their seeds, they can move from place to place. That is why you see new plants growing each year where there were none before. Flowering plants grow in many different colors and sizes, but they all have seeds. The part of the plant that holds the seeds is called the fruit. Some seed travel in their fruit. Others fall out and travel to a place where they can grow. But how they get to this new place? Some seeds stick to people's clothes or animals' fur and are carried from place to place. The seeds drop off and form new plants where they fall. Other seeds may be scattered by wind and rain. However it happens, seed certainly move.
