Board 常用作名词，意为”板，木板“等，经常出现用于构成复合词，如 blackboard（黑板），noticeboard（布告板）或 chessboard 等，但是 on board 却不是”在板上“的意思，它有很多延申的意思。 On board 是一个介词短语，它的字面意思是”在板上“，延伸义为”在船上（或飞机上、火车上） “，此时相当于 aboard，例如：1. on board: Have the passengers gone on board yet?乘客们登机了吗？Is there a doctor on board? We have a sick passenger.船上有医生吗？我们有一个生病的乘客。When everyone is on board, we will leave.等大家都上船了，我们就走。2. aboard:He was already aboard the plane.他已经登机了。The plane crashed killing all 157 passengers aboard.飞机坠毁，机上157名乘客全部遇难。
正是因为 on board 的这个意思， 它被用来比喻受雇于某人或与某人一起工作，因为大家都在一块”板上“；还可以延申意为“同意”，常用于搭配 on board with 中，例如： 1. on board:The entire class was on board for the excursion to the park.全班同学都准备去公园游览。It’s good to have you on board for this project.很高兴你能参与这个项目。Welcome to the company, Tom. We're all glad you're on board now.欢迎来到公司，汤姆。我们都很高兴能和你共事。2. on board with:Is the bride on board with the new seating plan?新娘同意安排吗？Is everyone on board with the new plan?大家都同意这个新计划吗？它还常用于搭配 take sth on board 中，意为”采纳，接纳“，例如：I told her what I thought, but she didn't take my advice on board.我把我的想法告诉了她，可她没有采纳我的建议。I shall be hoping that the council will take that message on board.我希望安理会能够采纳这一信息。I listened to them, took their comments on board and then made the decision.我听取了他们的意见，采纳了他们的意见，然后做出了决定。您的支持最重要！！！如果您觉得这篇文章对您有帮助，请不要吝啬在右下角点“在看”和点赞，我们将一如既往地输出更多优质的此类文章。
