汽船

The sailing ships were superseded by the steamships.

帆船已被汽船所。

The motorboat put on speed as soon as it left the pier.

汽船一离开码头就加快了速度。

Sometimes the 'classroom' is a Mississippi riverboat.

"有时候,教室就在密西西比河的汽船。"

The steamer arrived in harbor last night.

汽船是昨晚进港的。

The steamer edged off.

汽船徐徐离去。
