passive: be supposed to be [adjective]

同義詞
  • assume

    stronger — taking something for granted without evidence, often as a starting point for reasoning

  • presume

    stronger — based on reasonable probability rather than mere guesswork

  • guess

    less formal and more uncertain — based on little or no evidence

反義詞
  • know

    to be certain of something through proof or experience

文法句型

suppose + that-clause

suppose + so

用法筆記

The passive construction 'be supposed to' has a separate meaning related to obligation or expectation (e.g. 'You are supposed to wear a helmet'). Do not confuse it with this active sense.

常見錯誤

I am suppose to call him.
I am supposed to call him.
💡the past participle 'supposed' is needed after 'be' in the passive. 'Suppose' alone is active.
I suppose it is true, but I have no evidence.
I assume it is true, but I have no evidence.
💡'suppose' is more tentative and suggests some basis; 'assume' works better when there is no evidence at all.

同義詞
  • guess

    less formal and less emotionally charged — simply estimating rather than reluctantly accepting

  • expect

    more neutral — implies prediction without the sense of reluctance

文法句型

I suppose + that-clause (reluctant)

subject + supposed + would/could

用法筆記

Common in first-person 'I suppose...' to soften an unpleasant admission. The tone is reluctant rather than neutral. In third person, the reluctance is often conveyed through context such as 'after all' or 'would have to'.

clause-initial So I suppose you expect…

同義詞
  • I gather

    less confrontational — implies deduction rather than annoyance

文法句型

I suppose + you + think/expect (rhetorical)

用法筆記

Always in first person 'I suppose...' and followed by a rhetorical claim that the speaker finds unreasonable. The tone is sarcastic or confrontational — never neutral. Common in spoken arguments.

常見錯誤

Using this sense in formal writing: 'I suppose you think the report is fine.' (sarcastic tone is inappropriate for business reports)
It seems you are satisfied with the report.

例句

「也許你是對的,」Anong 說。「好吧,算是吧,」Caleb 回答。

short response: I suppose so

I suppose the cheaper option makes more sense with our budget.

好吧,便宜的選擇以我們的預算來說確實比較合理。

同義詞
  • I guess

    more casual and common in American English; slightly less reluctant in tone

  • concede

    more formal — used in debates and formal discussions

反義詞
  • deny

    to state that something is not true

文法句型

I suppose so

I suppose + clause (reluctant agreement)

用法筆記

Often appears as the short response 'I suppose so' or 'I suppose you are right.' Unlike sense 2 (UNWELCOME TRUTH), the focus here is on conceding a point in an argument, not on reluctantly facing an unpleasant fact.

5. used to make a suggestion or request less direct and therefore more polite

5.動詞及物B2
釋義

不如

委婉提出建議或請求

used to make a suggestion or request less direct and therefore more polite

例句

I suppose we could take a short break now and finish later.

我們不如先休息一下,等會兒再繼續。

I suppose we could (polite suggestion)

I suppose you could help me carry these boxes upstairs.

或許你可以幫我把這些箱子搬上樓。

I suppose you could (polite request)

同義詞
  • perhaps

    adverb used to soften suggestions; not a verb but serves a similar polite function

  • maybe we could

    more casual and slightly less tentative

文法句型

I suppose we could…

Suppose I/we… (direct polite offer)

I suppose you could…

用法筆記

The structure 'Suppose I/we…' (without 'I' before 'suppose') functions as a direct polite suggestion. The full 'I suppose we could…' form is softer and more hesitant. Both are common in British English for polite requests.

常見錯誤

Suppose you help me?' (sounds incomplete)
I suppose you could help me.' or 'Suppose I help you.
💡the polite suggestion structure works best with 'I' or 'we' as the subject of 'suppose'.

6. to require a particular situation or fact to be true as a necessary basis for so

6.動詞及物B2
釋義

預設

需要某條件成立事物才能合理

to require a particular situation or fact to be true as a necessary basis for something else to make sense or work properly

例句

The plan supposes that everyone will agree to work on Sunday.

這個計劃預設每個人都同意週日上班。

abstract subject: The plan supposes that…

This recipe supposes you have a food processor at home.

這個食譜預設你家裡有食物調理機。

同義詞
  • presuppose

    more formal and technical; implies a logical or philosophical precondition

  • require

    more general — can apply to people, things, or conditions

  • take for granted

    more informal — assuming something without checking

文法句型

plan / theory / budget / rule supposes that…

用法筆記

Unlike the other senses, the subject here is always an abstract thing (plan, theory, budget, system) — never a person. This sense is formal and common in academic, technical, and business contexts.

常見錯誤

I suppose your help.' (using this sense with a person as subject)
The plan supposes your help.
💡this sense requires an abstract subject.
