used to do这个短语翻译为“过去常常做某事”,例如:I used to play ball.过去我常常踢球。use doing是错误短语,没有use doing这个用法。 use的用法 1.use可以作动词和名词 (1)作动词时,“使用,利用,服用(毒品)” 过去式used,过去分词used,现在分词using. (2)作名词时,“使用,使用权,功能” 形容词useful,副词usefully 2.关于use的三个固定句型: (1)used to do sth."过去常常做某事" (2)be used to do sth."被用来做某事" (3)be used to doing sth"习惯做某事" 3.辨析: (1)used to do sth."过去常常做某事" to后加动词原形,否定句为didn't use to或used not to eg:I used to take a walk after supper every night. (我过去常常在每天晚上饭后去散步) (2)be used to do sth."被用来做某事" to后加动词原形 eg:Wood is used to make paper. (木材被用来造纸) (3)be used to doing sth"习惯做某事" to是介词,后加名词,动名词或代词 eg:He is used to getting up early. (他习惯早起) 本文来源:https://www.wddqw.com/doc/56fa8495332b3169a45177232f60ddccda38e6a6.html
