3. May we go on board to see your cockpit? 我们上飞机看看驾驶舱好吗?
4. The ship is about to start. Let’s go on board. 船就要开了,我们上船吧。
5. The sergeant made some kind of report, and some entry in a book, and then the convict whom I call the other convict was drafted off with his guard, to go on board first. 巡官做了汇报,又在本子上做了些记录,然后便让卫兵押着我不认识的那一个犯人先上监狱船去。
