Growing or spreading with nothing stopping it — used when the thing growing is bad. 'If the fire is left unchecked, it will reach the houses', 'unchecked corruption', 'The disease spread unchecked through the village.' Two things about how it is used.
Growing or spreading with nothing stopping it形容一直在長、一直在擴散，沒有東西能阻止它——used when the thing growing is bad用在成長或擴散的東西是壞事的時候。'If the fire is left unchecked, it will reach the houses', 'unchecked corruption', 'The disease spread unchecked through the village.'像 'If the fire is left unchecked, it will reach the houses'（如果放任火勢不管，火就會燒到房子）、'unchecked corruption'（不受控制的貪腐）、'The disease spread unchecked through the village.'（疾病在村子裡不受控制地蔓延）。Two things about how it is used關於用法有兩件事。
First, it nearly always sits after the noun or verb, not before: 'go unchecked', 'run unchecked', 'left unchecked' are the set phrases you will meet. Second, it carries a warning: the speaker is saying 'someone should be stopping this'.
First第一， it nearly always sits after the noun or verb, not before它幾乎都放在名詞或動詞後面，而不是前面： 'go unchecked', 'run unchecked', 'left unchecked' are the set phrases you will meet'go unchecked'、'run unchecked'、'left unchecked' 是你會遇到的固定搭配。Second第二， it carries a warning它帶著一種警告的語氣： the speaker is saying 'someone should be stopping this'說話的人其實是在說「應該要有人出來阻止這件事」。
Here 'check' has its older meaning of holding something back, like a dam checking a river — nothing to do with checking your homework.
Here在這裡， 'check' has its older meaning of holding something back'check' 用的是它比較舊的意思，「攔住、阻擋」， like a dam checking a river就像水壩攔住河水那樣——nothing to do with checking your homework跟「檢查作業」的 check 完全無關。
A separate, less common use does mean 'not examined' ('unchecked baggage', 'unchecked facts'), but the growing-out-of-control sense is the one you will meet most.
A separate, less common use does mean 'not examined'另外有一個比較少見的用法，意思是「沒被檢查過」（ 'unchecked baggage', 'unchecked facts'像 'unchecked baggage'（未經檢查的行李）、'unchecked facts'（未經查證的事實)）， but the growing-out-of-control sense is the one you will meet most但「失控地擴散」這個意思才是你最常會遇到的。

computingengineeringmathematicsOf a check box: not checked (ticked or enabled).
- This pseudocode is unambiguous if we know that the previous state of all the boxes is "unchecked." Because we can't be sure of that in buggy code, a better model might be: […]
- Check boxes are a handy way to enable users to select one or more options that are not mutually exclusive. […] By default, [Microsoft] Word displays boxes unchecked.

Of a square: part of only one entry (that is, across or down, but not both).
- If there are W#95;1 "unchecked" whites (that is, those which enter into the solution of one clue only), and W#95;2 "checked" whites (those which enter into the solution of two clues), then the mean word length will be (W#95;1#43;2W#95;2)#47;C, where C is the number of clues. […] Acceptable (if unwelcome) difficulties arise when the initial letters of words occupy unchecked squares, because no hint then derives from other clues as to how that word will start. In six consecutive crossword puzzles in The Times, 16 per cent of the words had unchecked initial letters.
- On a crossword puzzle grid, you shouldn't encounter any unchecked squares – white squares that are used in an Across entry but not in a Down entry, or vice versa. If unchecked squares were allowed, that would make your life harder – you'd have only one opportunity to figure out what belongs in that square. Instead, you always get two chances to fill a square: by solving the Across clue or the Down clue.
