    nearly synonymous but slightly more general; includes hospital emergency room staff who may not go to the scene

文法句型

first responder

emergency responder + verb (arrive / help / rescue)

responder + at / on + [location]

用法筆記

Often used in the compound noun 'first responder', which describes a person with special training who is among the first people to arrive at an accident or emergency. The plural 'responders' is very common when referring to organised response teams (police, fire, medical services working together).

常見錯誤

The firefighter is a first responder to the scene.
The firefighter is a first responder at the scene.
💡'first responder' is a role title, not a verb phrase; use 'at' or 'on' for location, not 'to'.

scenario: forum posting with multiple responders in a reply context

同義詞
  • respondent

    more formal; preferred in legal, research, and official contexts

  • answerer

    very rare in modern English; use 'responder' or 'respondent' instead

  • replier

    informal and less common; 'responder' is the standard choice

文法句型

responder + to + [question / message / email]

adjective + responder (quick / slow / first)

用法筆記

Less formal than 'respondent'. This sense is common in everyday workplace communication (emails, meetings, chat groups). The pattern 'first responder to + [question/topic]' is particularly frequent in meeting contexts but is distinct from the compound 'first responder' in sense 1.

He is a fast responder.
💡The adjective must come before the noun in English noun phrases.

  • interviewee

    specific to face-to-face or telephone interview settings

文法句型

survey responder

responder + in + [study / survey / poll]

responder + to + [questionnaire]

用法筆記

In formal research writing, 'respondent' is more common than 'responder'. However, 'responder' appears frequently in spoken research contexts, data reports, and informal academic discussion. The preposition 'in' (not 'of') is used: 'responders in the study'.

常見錯誤

There were 200 responders of the survey.
There were 200 responders in the survey.
💡Use 'in' (not 'of') when stating the number of participants in a study.

4. a patient whose medical condition improves as a result of a specific treatment,

4.名詞C1
釋義

有反應者

對治療產生正面療效的病人

a patient whose medical condition improves as a result of a specific treatment, drug, or therapy — for example, a cancer patient whose tumour shrinks after chemotherapy, or a person whose blood pressure drops after taking medication.

例句

About sixty percent of patients were good responders to the new cancer drug.

大約六成的患者對這種新的抗癌藥物出現治療反應。

pattern: good/poor responder + to + [treatment]

Doctors classified Henry as a responder because his symptoms improved after six weeks of treatment.

醫師判定 Henry 為有反應者,因為他的症狀在治療六週後有所改善。

verb: classify + as + a responder

同義詞
  • respondent

    not used in this medical sense; 'respondent' is legal/research, not clinical

  • good responder

    specifies that the response was strong or complete

  • partial responder

    indicates that improvement was present but limited

反義詞
  • non-responder

    a patient who does not improve with the given treatment

文法句型

responder + to + [treatment / drug / therapy]

good responder / poor responder

用法筆記

Primarily used in medical research and clinical contexts. The term is often paired with its opposite 'non-responder'. The preposition 'to' is required before the treatment: 'a responder to the vaccine'. In everyday hospital conversation, doctors may say 'he responded well' rather than 'he was a responder'.

常見錯誤

She is a responder of the treatment.
She is a responder to the treatment.
💡Use 'to' (not 'of') when specifying the treatment a patient responded to.
