托马斯和他的朋友们是一部备受欢迎的卡通动画片，它讲述了一群火车在互相帮助、探险和学习中成长的故事。而这部动画片的主题曲也成为了许多孩子们喜爱的歌曲。下面是这首英文歌曲的歌词：

They're two, they're four, they're six, they're eight

Shunting trucks and hauling freight

Red and green and brown and blue

They're the really useful crew

All with different roles to play

Round Tidmouth Sheds or far away

Down the hills and round the bends

Thomas and his friends

Thomas, he's the cheeky one

James is vain but lots of fun

Percy pulls the mail on time

Gordon thunders down the line

Emily really knows her stuff

Henry, toots and huffs and puffs

Edward wants to help and share

Toby, well let's say, he's square

They're two, they're four, they're six, they're eight

Shunting trucks and hauling freight

Red and green and brown and blue

They're the really useful crew

All with different roles to play

Round Tidmouth Sheds or far away

Down the hills and round the bends

Thomas and his friends

这首歌曲以欢快的旋律和歌词，向我们介绍了托马斯和他的朋友们的形象和性格。从歌词中可以看出，这些火车拥有着不同的角色和任务，但他们都是非常有用的团队成员。无论是在Tidmouth Sheds周围还是远离家乡的地方，他们都会在山丘和弯道上穿梭，互相帮助和学习。

托马斯是一个调皮的角色，詹姆斯则虚荣但非常有趣，珀西总是能准时地拉邮件，而戈登则是一位威风凛凛的火车。爱米丽则非常懂得自己的本领，亨利则总是呼啸着前进，爱德华则希望能帮助和分享，托比则是一个矩形的形状。

总之，这首主题曲让我们更好地了解了托马斯和他的朋友们，也让我们感受到了友谊和团队精神的力量。
