A withdrawn person is very quiet and shy, keeping their thoughts to themselves and not joining in. The picture inside the word is someone stepping back out of the room: they are still there, but they have pulled away from other people.

A withdrawn person 一個withdrawn的人 is very quiet and shy 非常安靜、害羞, keeping their thoughts to themselves 把自己的想法都藏在心裡 and not joining in 不參與別人。The picture inside the word 這個詞裡面的畫面 is someone stepping back out of the room 是一個人從房間裡往後退出去: they are still there 他們人還在, but they have pulled away from other people 但已經從其他人身邊抽離了

The important thing is the feeling behind it. 'Quiet' is neutral, 'shy' is common and harmless, but 'withdrawn' usually suggests something is wrong. It is the word teachers, doctors, and worried parents use: 'He's become very withdrawn since his father died.' 'The child was withdrawn and would not look at anyone.' It often points to sadness, depression, or shock. So it is not a nice word for someone's personality; it is closer to a warning.

The important thing 重要的是 is the feeling behind it 這個詞背後的感覺。'Quiet' is neutral 「Quiet」是中性的, 'shy' is common and harmless 「shy」很常見也無害, but 'withdrawn' usually suggests something is wrong 但「withdrawn」通常暗示有什麼地方不對勁。It is the word teachers, doctors, and worried parents use 這是老師、醫生跟擔心的父母會用的詞: 'He's become very withdrawn since his father died.' 「他父親過世後變得非常withdrawn。」'The child was withdrawn and would not look at anyone.' 「這孩子很withdrawn，不看任何人。」 It often points to sadness, depression, or shock 這常常指向悲傷、憂鬱或受到打擊。So it is not a nice word for someone's personality 所以這不是形容個性的好聽詞; it is closer to a warning 它比較接近一種警訊

Because of that, you will very often see it with 'become' or 'seem' — it describes a change, not just how someone always is: 'She has become withdrawn.' You can also use it before a noun ('a withdrawn teenager'), though after the verb is more common.

Because of that 正因為這樣, you will very often see it with 'become' or 'seem' 你很常會看到它跟「become」或「seem」一起出現 — it describes a change 它描述的是一種變化, not just how someone always is 而不只是一個人一直以來的樣子: 'She has become withdrawn.' 「她變得withdrawn了。」 You can also use it before a noun 你也可以放在名詞前面 ('a withdrawn teenager') 「a withdrawn teenager」, though after the verb is more common 不過放在動詞後面比較常見

Be careful with the spelling, because 'withdrawn' is also the past participle of the verb 'withdraw' (to take back or take out), and that use is everywhere: 'money withdrawn from the account', 'the offer has been withdrawn', 'troops were withdrawn'. Same word, completely different job. The sense here is the personality one.

Be careful with the spelling 拼法要小心, because 'withdrawn' is also the past participle of the verb 'withdraw' 因為「withdrawn」也是動詞「withdraw」的過去分詞 (to take back or take out) （拿回來或提出來）, and that use is everywhere 而且這個用法到處都是: 'money withdrawn from the account' 「money withdrawn from the account」, 'the offer has been withdrawn' 「the offer has been withdrawn」, 'troops were withdrawn' 「troops were withdrawn」。Same word, completely different job 同一個字，完全不同的功能。The sense here is the personality one 這裡講的是形容個性的那個意思
