✔ 最佳答案
used to
used + infinitive ( with to ) ,
used + infinitive 表示一個 * 現在已中斷 * 的過去的習慣 ,
或與現在不同的過去狀況 ,
e.g.
She used to dislike Tom but she quite likes him now .
He used to drink beer ; now he drinks wine .
若沒有和現在作對比 , 只述說過去的習慣 , 可用 would ,
Every morning Tom would kiss Ann and set off for work .
used 作形容詞時 , 意為 accustomed ( 已習慣於某事 ) ,
be used to 的 to 是 preposition ,
be used to + noun / pronoun / gerund ,
e.g.
I am used to noise .
I am used to working in a noisy room .
( 意指我在嘈雜的房間工作過 , 因此吵鬧聲不會打擾我 , 我不介意 )
I used to 跟 I am used to 是不同的 ,
