反義詞

文法句型

single + noun

用法筆記

Frequently used in negative and emphatic contexts: 'not a single…', 'every single…'. Compare with the determiner 'a' — 'single' adds emphasis that the number one really matters. Distinguish from sense 3 (SEPARATE): this sense focuses on counting one, not on viewing something as an individual unit.

常見錯誤

I ate a single apple, not two.
I ate only one apple.' or 'I ate a single apple (for emphasis).
💡'a single' is correct for emphasis, but plain 'one' is more natural in neutral counting.

2. having no husband, wife, or romantic partner.

a single person

用法筆記

This is the most common everyday meaning of 'single'. For people who have never married, use 'never-married' for precision; 'single' covers both never-married and divorced people who are not currently in a relationship. Can also be used as a noun in the plural: 'singles' (see noun sense 5).

常見錯誤

I'm single with no kids.
I'm single and have no children.
💡'single with no kids' is acceptable in informal speech but avoid in writing; 'single' alone covers the relationship status.

例句

  • separate

    emphasises being apart from others

  • distinct

    formal, stresses clear differences between items

反義詞

文法句型

each single + noun

every single + noun

用法筆記

Often paired with 'each' or 'every' to stress that every individual member of a group matters separately. Distinguish from sense 1 (ONE): sense 1 counts 'just one' in total, while sense 3 singles out each item in a larger set. Distinguish from sense 4 (SINGLE-SIZE): sense 4 says something is designed for use by one person, not that it is being considered separately.

4. meant for a person on their own, such as a bed or room that fits just one occupa

4.形容詞B1
釋義

meant for a person on their own, such as a bed or room that fits just one occupant.

例句

collocation: 'single bed'

collocation: 'single room'

同義詞
反義詞

文法句型

single + bed / room / portion

用法筆記

Only used before nouns describing items that come in different sizes for different numbers of people (beds, rooms, seats, servings). For 'single room' this is also a countable noun (see noun sense 7). Not to be confused with sense 3 (SEPARATE): a 'single bed' is a bed for one person, not a bed that is being considered on its own.

常見錯誤

I need a single ticket for one person.
I need a single ticket' (this is the ticket type) or 'I need one ticket.
💡'single ticket' already means one-way ticket (British) or one admission; it does not usually mean 'for one person'.
