Answer 1

分析 used to play，am used to swimming

解答 答案：used to play，am used to swimming．表示過(guò)去常常用used to do sth，打籃球play basketball．習(xí)慣于做某事be used to doing sth，表達(dá)的是客觀事實(shí)用一般現(xiàn)在時(shí)，主語(yǔ)I，故am，故答案是used to play，am used to swimming

點(diǎn)評(píng) 1、used to do sth．
    used to 意為"過(guò)去常常"，可看作半助動(dòng)詞或情態(tài)動(dòng)詞，其后跟動(dòng)詞原形，表示過(guò)去的習(xí)慣、經(jīng)常發(fā)生的動(dòng)作或狀態(tài)．如：
    He used to be a teacher in our school．他曾經(jīng)是我們學(xué)校的一位老師．
2、be used to doing sth．
    be used to doing sth．表示"習(xí)慣于做某事"，其中to是介詞，后接名詞或動(dòng)名詞．如：
    The old man and his wife have been used to living a simple life．這對(duì)老夫婦已經(jīng)過(guò)慣了簡(jiǎn)樸的生活．
