1·Is it a meatball sub?
是肉丸潜水艇吗？
2·Why? We're decommissioning outdated ships that are better than 90% of their sub fleet… unless you're really concerned that all those diesel engines will pollute the oceans.
为什么？我们那些过期的舰船正要退役，比他们90%的潜水艇都还要好…除非你是担心那些柴油动员机遇传染大陆。
3·He bit the front of the sub; boy, that - that's not a confidence builder.
它在咬潜水艇的前端，哎呀，那可不是一个有信心的建筑部位。
4·One, an old barque, had been big enough for a sub to bother with and the sub had shelled her.
一条是陈旧的敞篷汽艇，比较大。潜水艇要搞掉它还真得费点儿力气，而它也确实挨了潜艇的炮弹。
5·I was nervous enough about just coming down here in a homemade sub. I didn't realize we'd have a 5-meter shark biting it, too!
我乘坐自制潜水艇下潜已经感到很紧张了，更没有料到的是，竟然还会有5米长的鲨鱼来咬它！
