文法句型

thoroughly + adjective (thoroughly modern)

thoroughly + past participle (thoroughly impressed)

thoroughly + verb of emotion (thoroughly enjoyed)

用法筆記

Frequently appears with verbs that express enjoyment (enjoy, love, appreciate), approval (impress, recommend, approve), or strong emotional states (disappoint, amaze, embarrass, shock). Less natural with concrete action verbs — you would check the tyres thoroughly (sense 2) rather than thoroughly check the tyres when the focus is on manner rather than degree.

❌I thoroughly ate the whole pizza.
✅I ate the whole pizza.
💡'thoroughly' is not used to mean 'completely finish eating something'; it expresses depth or care, not simple completion.
❌He studied thoroughly the report.
✅He studied the report thoroughly.
💡when 'thoroughly' follows a transitive verb + object, it must go after the object, not between the verb and object.

verb + object + thoroughly (cleaned … thoroughly) — post-verbal position

同義詞
  • carefully

    broader — applies to any action done with caution; does not necessarily imply completeness

  • meticulously

    more formal; stresses extreme attention to small details

  • exhaustively

    even stronger — implies every possible aspect has been covered

  • comprehensively

    focuses on covering all parts rather than depth of each part

反義詞
  • carelessly

    suggests skipping steps or not paying attention

  • superficially

    indicates only the surface or most obvious parts were covered

文法句型

thoroughly + verb of examination (thoroughly checked)

verb + object + thoroughly (checked the car thoroughly)

passive + thoroughly + past participle (was thoroughly cleaned)

用法筆記

Typically modifies verbs that imply systematic or methodical action: examine, check, investigate, clean, review, search, prepare, research, test. When the verb has a direct object, thoroughly can go before the verb (thoroughly checked the brakes) or after the object (checked the brakes thoroughly); the post-object position is more neutral in spoken English.

✅She cleaned the house thoroughly.
💡'thoroughly' is an adverb, not a verb; it must modify a verb, not replace it.
❌I thoroughly forgot your name.
✅I completely forgot your name.
💡'thoroughly' is not used with verbs of forgetting or simple mental absence; use 'completely' or 'totally' instead.
