例句

    implies complete elimination of a disease, not just management

    broader, includes nursing and comfort beyond medical procedures

反義詞

    to fail to give medical care to someone who needs it

文法句型

treat + person + for + condition

treat + condition + with + method/substance

passive: be treated for [condition]

用法筆記

The direct object can be the person receiving care ('treat a patient'), the illness ('treat cancer'), or the body part ('treat a wound'). When specifying the illness, use 'treat someone for [condition]'.

常見錯誤

The doctor treated for his cold.
The doctor treated him for his cold.
💡'treat' always needs a direct object before 'for'.

3. to cover the cost of something nice for another person, often as a generous act

3.動詞及物A2
釋義

to cover the cost of something nice for another person, often as a generous act or to mark a special event — for instance, paying for a friend's dinner or getting yourself a spa day as a reward.

例句

Omar offered to treat his coworkers to lunch after they finished the big project.

treat + someone + to + meal

Let me treat you to a cup of coffee at the new cafe downstairs.

同義詞
  • pay for

    more transactional; lacks the generous, celebratory tone of 'treat'

  • take someone out

    phrasal verb; implies going to a restaurant or event together

文法句型

treat + someone + to + something

treat + yourself + to + something

treat + [group] + to + [food/event]

用法筆記

Always followed by 'to' when specifying what is paid for ('treat someone to lunch'). Never use a direct object without 'to' ('treat someone lunch' is incorrect). Can be used reflexively ('treat yourself') to mean doing something special for yourself.

常見錯誤

I will treat you a dinner.
I will treat you to a dinner.
💡The preposition 'to' is required before the thing being paid for.

passive: be treated + with + substance + purpose clause

Liang treated the metal surface with an anti-rust coating before painting it.

treat + surface + with + substance

同義詞
  • process

    broader; can involve any series of steps, not just applying a substance

  • coat

    specifically means covering a surface with a layer of something

文法句型

treat + material + with + substance

be treated to + verb (infinitive of purpose)

passive: is treated + adverb/purpose clause

用法筆記

Almost always found in passive voice in technical or instructional writing. The agent is often a chemical substance rather than a person. For the general sense of 'process', this term appears in manufacturing, construction, and chemistry contexts.
