be used to接動(dòng)詞原形， 表示“被用來做某事”（如1）;而be / get used to后接名詞、代詞或動(dòng)詞-ing形式，表示“習(xí)慣于;適應(yīng)”（如3和4）。

ability既指天賦的“能力”(如3)，也指培養(yǎng)造就而獲得的“本領(lǐng)；才能”或已經(jīng)表現(xiàn)出來的實(shí)際“能力”(如1和4)。
capacity 用于物時(shí)，指“（容納接受的）能力”（如7）;生產(chǎn)能力（如5），有時(shí)可翻譯為“容量;容積”；用于人時(shí)，一般不指體力，多指才智、道德等方面，尤其指接受能力等（如4）。
potential表示“潛在的能力;可能性”（如2和6）。
