Section 2 · Reading and Writing: meaning, manipulation and synthesis
Exam scope and assessment notes
Partial course: shared skills, topic sequences for the 2026–2029 essay lists and selected wider-topic readings, not full AS preparation. Fictional exercises are labelled as such. Source-based lessons identify real publications, dates and original StudyForA paraphrases separately from our analysis; they do not establish the current situation or represent an entire country. Portuguese examples mainly use European Portuguese; obtain specialist feedback on regional usage, language accuracy and cultural evidence. Written comparisons are self-checks, not AI or Cambridge grades. There is no pronunciation assessment, live examiner, comprehensive authenticated contemporary reading bank or calibrated full-paper marking. This lesson uses original fictional teaching material, not factual cultural reporting.
Before you begin
- Read connected Portuguese at roughly IGCSE/O Level standard
- Distinguish information supplied in a text from a personal opinion
Work on paper. Try each question before revealing help, and explain why your method works.
Quick readiness check
Which approach makes a defensible language answer?
What you will learn
- Preserve time, participants and degree of certainty during grammatical manipulation
- Use agreement and indicative or subjunctive forms appropriate to the specified meaning
Escrever e comparar
- Leia os textos e responda em português antes de abrir a comparação.
- As respostas são exemplos: uma formulação diferente pode ser válida se respeitar o texto e a pergunta.

Prática original
Os contextos e dados são fictícios. Justifique as inferências e não invente factos sobre países.
1. Corrija “Haviam duas salas e elas foi abertas pela equipa”. Explique as duas correções.
Comparar depois de tentar
Havia duas salas e elas foram abertas pela equipa. O verbo haver, com sentido de existir, usa aqui a terceira pessoa do singular. Na segunda oração, o sujeito elas é plural, por isso o auxiliar deve ser foram; abertas já concorda no feminino plural com salas.
Como melhorar
- Distingue haver impessoal do auxiliar com sujeito plural.
- Corrige a forma sem alterar o número de salas ou o agente.
Keep a meaning checklist
A grammatical transformation has two tests: the requested form must be correct, and the original meaning must survive. Note the subject, time, negation and modality before rewriting. “A equipa divulgou o horário” can become “O horário foi divulgado pela equipa”. The passive changes the focus; it does not make the action present or remove its agent when the task asks you to retain it.
Agreement follows the new structure. “As salas foram abertas” needs plural feminine abertas and plural foram. “A sala foi aberta” is singular. Do not reuse an ending mechanically after changing the noun. In ordinary formal usage, existential haver remains singular: “Havia duas salas”, rather than “Haviam duas salas”.
A condition is not an accomplished event
“Se houvesse mais voluntários, a sala abriria ao domingo” expresses a hypothetical condition using imperfect subjunctive houvesse and conditional abriria. It does not state that more volunteers exist. “Se houver mais voluntários, a sala abrirá ao domingo” presents a possible future condition. Use the version the question asks for.
A repeated past situation and a completed event also differ: “Todos os sábados, Marta estudava na biblioteca” describes a past habit. “No sábado passado, Marta estudou na biblioteca” presents a bounded occasion. When asked to change time, the context must change coherently. These are selected foundations, not an exhaustive grammar syllabus or a rule that one regional variety is the only valid Portuguese.

Worked example
Reescreva na voz passiva: “A associação reservou duas salas.” Mantenha o agente.
Show the worked solution
- “Duas salas” passa a sujeito.
- Use “foram reservadas” para o plural feminino.
- Mantenha “pela associação”.
Answer Duas salas foram reservadas pela associação. O tempo continua passado, o número de salas mantém-se e o agente continua identificado.
From guided practice to a new situation
Write your answer and reasoning first. Use a hint only if you are stuck. The model solution is for self-checking; your written work is not automatically marked.
Guided: Passe “A equipa abriu a biblioteca” para a voz passiva, mantendo o agente.
Give me a hint
Faça da biblioteca o sujeito da nova frase.
Compare my reasoning
- Identifique o objeto feminino singular.
- Use “foi aberta”.
- Acrescente o agente.
A biblioteca foi aberta pela equipa. O particípio aberta concorda com biblioteca, feminino singular. O auxiliar foi mantém o acontecimento no passado, e pela equipa conserva a informação sobre quem realizou a ação. A transformação muda o foco da frase sem acrescentar um novo acontecimento.
Look for these in your work
- Correct passive
- Agreement and tense
- Retains the agent
Independent: Complete a hipótese: “Se ___ mais lugares, todos ___ estudar aqui.” Use haver e poder numa situação hipotética.
Give me a hint
Use o imperfeito do conjuntivo e o condicional.
Compare my reasoning
- A existência de lugares é hipotética.
- Haver existencial fica no singular.
- Poder concorda com todos.
Se houvesse mais lugares, todos poderiam estudar aqui. Houvesse exprime uma situação imaginada, e poderiam apresenta a consequência possível dessa condição. A frase não confirma que os lugares adicionais existam. O singular de houvesse não depende do plural lugares, porque haver tem aqui sentido existencial.
Look for these in your work
- Uses houvesse
- Uses poderiam
- Preserves hypothetical meaning
Application: Explique a diferença entre “Marta estudava aqui todos os sábados” e “Marta estudou aqui no sábado passado”.
Give me a hint
Compare hábito e ocasião delimitada.
Compare my reasoning
- Observe a expressão temporal de cada frase.
- Associe estudava ao hábito.
- Associe estudou à ocasião concluída.
A primeira frase descreve um hábito no passado: o estudo repetia-se aos sábados. A segunda refere uma ocasião delimitada, o sábado passado. Ambas estão no passado, mas apresentam o tempo de maneiras diferentes. Trocar apenas a forma verbal, sem respeitar a expressão temporal e a intenção, pode alterar o significado.
Look for these in your work
- Distinguishes aspect
- Uses the time expressions
- Explains the change in meaning
Common mistakes
- Changing a hypothetical proposal into a fact
- Losing negation
- Using singular agreement with a plural subject
- Confusing past habit with one completed occasion
What can you explain now?
Which sentence preserves a hypothetical shortage of volunteers?
Compare with the explanation
Se houvesse mais voluntários, a sala abriria ao domingo
The condition is hypothetical; it is not a report that the Sunday opening happened.
