- Master common adjective-preposition collocations.

O que você vai aprender
Link ideas with clauses of contrast, purpose, and reason; use adjective + preposition pairs; and distinguish during, for, and while.
-
Clauses of Contrast, Purpose, and ReasonSubordinate clauses add meaning to main clauses. Contrast clauses show opposition (although, even though, despite). Purpose clauses show why (to, so that, in order to). Reason clauses explain cause (because, since, as).
-
Adjective + Preposition: Interested IN, Good AT, Afraid OFMany adjectives are always followed by a specific preposition. These are fixed collocations that must be memorised — the preposition cannot be changed.
-
During, For, and While: Expressing TimeDuring + noun (refers to a period). For + duration (how long). While + clause (subject + verb, two things happening at the same time).
-
Indirect Questions: Could You Tell Me Where...?Indirect questions are politer and more formal than direct questions. After the introductory phrase, use statement word order (not question word order) — no inversion, no do/does/did.

Erros comuns
The adjective 'interested' always takes 'in', not 'on'.
In indirect questions, the verb must come after the subject.
'During' is used for a noun event, while 'for' is used for a duration of time.
