文法句型

serial + noun (criminal/offender/killer)

用法筆記

Only used before a noun (attributive position). The noun that follows is almost always a type of criminal or a harmful act. Common examples: serial killer, serial offender, serial rapist, serial arsonist, serial fraudster. The sense does not extend to non-criminal repeated behaviour (e.g. a person who watches many movies is not a 'serial movie-watcher').

He bakes cakes every weekend.
💡'serial' in this sense is reserved for criminal or seriously harmful repeated acts, not everyday habits.
The serial killer was arrested and put in jail for life.
The serial killer was convicted and sentenced to life in prison.
💡use 'convicted' and 'sentenced' rather than vague 'put in jail' for formal legal contexts.

文法句型

serial + noun (drama/novel/publication/story)

用法筆記

Used attributively before nouns related to media content. The noun typically names a type of creative work: drama, story, novel, publication, podcast. Contrasts with 'standalone' or 'one-off', which describe works that are complete in a single part.

常見錯誤

I bought a serial book.
I read a story that was published in serial form.
💡'serial' describes the publication format, not a type of book. Use 'serialised' or 'in serial form' instead.

3.形容詞B2
釋義

describes a way of sending data through a single wire or channel, where each piece of information travels one at a time in a line — for example, an older computer port that transmits data this way.

例句

Older computer mice used a serial port at the back of the machine.

serial + port for hardware connection

A serial cable sends one bit of data at a time through a single wire.

serial cable transmits one bit at a time

同義詞
  • sequential

    broader term for any step-by-step process, not specific to computing hardware

反義詞
  • parallel

    describes data transmission where multiple bits travel simultaneously through separate wires

文法句型

serial + noun (port/cable/connection/interface)

用法筆記

Technical computing term. The opposite concept is 'parallel', where multiple bits travel at the same time through separate wires. Modern computers rarely include serial ports, though the term is still used in networking and hardware specifications.

常見錯誤

My phone uses a serial charger.
My phone uses a USB charger.
💡'serial' refers to a specific data transmission standard, not a general type of cable or charger.

4.形容詞B1
釋義

placed in a specific order following a numbered system, usually for identification purposes — for example, a product number that increases by one for each new item made.

例句

Every product from this factory has a unique serial code printed on its bottom.

serial code for unique identification numbers

Eitan wrote down the serial number of his laptop in case it got stolen.

同義詞
  • sequential

    broader term meaning 'one after another', used for any ordered arrangement

  • consecutive

    emphasises that items follow each other without gaps (e.g. consecutive numbers 1, 2, 3)

反義詞
  • random

    describes items that are not arranged in any fixed order

文法句型

serial + noun (number/code/order/ID)

用法筆記

Used before nouns that refer to identifiers or labels. The most common collocation is 'serial number', which identifies a single item uniquely. 'Serial code' and 'serial ID' are also frequent. This sense does not carry any criminal or media meaning — it simply means 'in a numbered sequence'.

常見錯誤

Please tell me the serial of your phone.
Please tell me the serial number of your phone.
💡'serial' alone is not a noun meaning 'identification number'; always include the word 'number' or 'code'.
