Introduction Ships and boats carry people and goods over water. Ships and boats were once the fastest way to move things.

引言 轮船和小船能载人、运货，穿越水域。 曾经，轮船和小船是运输货物最快的方式。

Early Ships and Boats The first boats were made out of logs. People used poles to push the boats.

早期的轮船与小船 最早的小船是用原木制作的。 人们用长杆撑着小船前进。

Other boats used paddles or oars. The oars pushed against the water to move the boats.

还有的小船用短桨或者长桨驱动。 船桨划动水面，推着小船往前走。

Later, people made boats with wooden frames. They covered the frames with bark or animal skins.

后来，人们造出了带有木框架的小船。 他们用树皮或者兽皮蒙在框架外面。

Frame boats were larger than log boats. Many people could row at the same time.

带框架的船比原木做的船更大。 好多人可以同时一起划船。
