p.s. active轉passive~
最重要認清主動句中的主角 - 動詞 - 配角~
(綠色字為主要被動句~ 其他為附加的枝節~)
動詞要注意原本的 tense~ 跟住黎變~
(be [is/am/are/was/were/been/being] + past participle)
還要留意主角是否有必要存在~
(They, it 之類不知道是誰的~ 其實都可以不用加 "by___"~)
↑上面 ( ) 代表可加可不加~ [ ] 代表最好不要加~
Hope this helps~~

Used to is not a transitive verb here and hence cannot be transformed into passive form.
