Unbreakable means it cannot be broken. The plain physical use is about objects that survive being dropped or hit: unbreakable glass, unbreakable plates for small children, an unbreakable phone case. Be honest with students about how this is really used — much of the time it is advertising language, and 'unbreakable' in a shop means 'very hard to break', not literally impossible.

Unbreakable unbreakable means的意思是 it cannot be broken不能被打破。The plain physical use最直接的物理用法 is about objects that survive being dropped or hit是指那些摔了或撞了也不會壞的東西: unbreakable glass, unbreakable plates for small children, an unbreakable phone caseunbreakable glass（摔不破的玻璃）、給小小孩用的unbreakable plates（摔不破的餐盤）、unbreakable phone case（摔不壞的手機殼）。Be honest with students about how this is really used老實跟學生說這個字實際上怎麼被用 — much of the time it is advertising language很多時候它是廣告用語, and 'unbreakable' in a shop means 'very hard to break'店裡說的'unbreakable'意思其實是「很難打破」, not literally impossible不是真的完全不可能。

The second use is just as common and more interesting: things that are not objects at all but that we imagine as things that could snap. An unbreakable promise, an unbreakable bond between two people, an unbreakable habit, an unbreakable record in sport (nobody will ever beat it), an unbreakable code (nobody can read it). In each case English is treating a promise or a friendship like a stick or a rope. There is also 'unbreakable spirit' — a person who cannot be crushed.

The second use第二種用法 is just as common and more interesting一樣常見，也更有意思: things that are not objects at all用在完全不是實體物品 but that we imagine as things that could snap卻被我們想像成「可能斷掉」的東西上。An unbreakable promise像an unbreakable promise（絕不會被打破的承諾）, an unbreakable bond between two people兩個人之間的unbreakable bond（牢不可破的情誼）, an unbreakable habit an unbreakable habit（改不掉的習慣）, an unbreakable record in sport體育界的unbreakable record (nobody will ever beat it)（永遠不會被打破的紀錄，沒有人能超越）, an unbreakable code an unbreakable code（沒有人能破解的密碼） (nobody can read it)。In each case每一個例子裡 English is treating a promise or a friendship英文都是把一個承諾或一段友誼 like a stick or a rope當作一根棍子或一條繩子在看待。There is also還有 'unbreakable spirit''unbreakable spirit'（不屈不撓的精神） — a person who cannot be crushed形容一個怎麼壓都壓不垮的人。
