scrape (the bottom of) the barrel to use the worst people or things because that is all that is available (因别无选择)将就，凑合用 scrape /skreɪp/ v. 用工具刮；刮掉；擦伤；挖坑 barrel /'bær(ə)l/ 大桶，用来载运啤酒、威士忌、食糖、汽油等各种货品。 它的出处可能是酒桶里仅仅剩下桶底那一丁点儿的酒了，实在要喝就只能刮桶底。刮桶底取上来的酒有沉淀甚至还混着木屑，会好喝吗? 想必不行，所以刮桶底是百般无奈才出此下策的。 Richard's in the team? You really are scraping the bottom of the barrel! 理查德进队了?你真是没人可用了!
