你如果把信封倒過來，鑰匙就會掉出去。
take…off 把……拿開
e.g. Will you take your books off the table?

【拓展】
take away & take off
在take away 與take off 這兩個短語中，take 都是“拿、帶”的意思，away 和off 是副詞，都可以表示“離開、離去”的意思。
從字面意思及結構看，這兩個短語很容易被混淆。其實，這兩個短語的意思和用法相差很遠。
take away 可表示“拿走”、“使離開”、“減去”等意思。如：
His sister wants to take away this book.
他的姐姐想拿走這本書。
The girl was taken away from school.
女孩被帶離學校。
Take away 3 from 6 and you get 3.
6減3等于3。
