“不知道要寄出” 英文怎樣寫?
Didn't know it / that should be mailed
OR
Didn't know (I / we) should send it by post
mail 或 post 作動詞用是指 ‘寄出信件(letters)或包裹(parcels or packages)’等。
必定要用 past tense ‘didn't know’, 因為你說或寫這一句時已肯定知道要寄出那些東西, 不能用 ‘don't know’。所有之前不知道的/忘記的, 現在知道/記起了, 需要用過去式動詞如 ‘I didn't know that’、‘I forgot to bring the bag’。
