确实要看上下文,因为"本来"的意思太多了。 1.in the first place 我本来就没指望他会来。（所以他没来我也不吃惊）I didn't expect him to come in the first place. (so I wasn't surprised he didn't show up.) 我们在讨论一个本来不是问题的问题。We are discussing a problem that should not exist in the first place! 2.直接用过去时 我本来就知道的（不用你说）I KNEW it. 3.used to 她本来是个乖孩子(现在变了) She used to be a well-behaved girl. 4.should have / could have 你本应该阻止他(你却没有) You should have stopped that guy. 我们本来可以赢的(输得冤枉) We could have won the game.
