Overview
How This Grammar Works
Eu acho que devemos agir(I think we should act), you'd say,
É preciso agir(It's necessary to act), which carries more weight. Similarly,
É importante considerar todos os ângulos(It's important to consider all angles) conveys an objective truth.
Vendem-se carros aqui(Cars are sold here / One sells cars here) focuses on the action of selling cars, not who is doing the selling. This is widely used in official documents and academic papers.
there is/are, as in Há muitas razões para essa conclusão(There are many reasons for this conclusion). This contrasts with the more informal ter, often used in spoken Portuguese.
Observou-se que...(It was observed that...),
Verificou-se que...(It was verified that...), or
Constatou-se que...(It was found that...) allow you to present findings objectively, attributing the observation to a general process rather than a specific individual. For example,
Verificou-se que os dados são consistentes(It was verified that the data are consistent) lends credibility and formality to your report.
Common Mistakes
- 1✗ Wrong: Eu acho que é necessário mais investigação.
Eu acho (I think). The correct version uses the impersonal expression É necessário to present the statement as an objective fact or requirement, lending more authority and formality to the writing.- 1✗ Wrong: Os problemas resolvem-se facilmente.
solve themselves) instead of the impersonal/passive se. The correct understanding is that the problems *are solved* by an unspecified agent, which is the objective and formal use of the se particle.- 1✗ Wrong: Tem muitas opções disponíveis.
there is/are). While ter is frequently used impersonally in informal spoken Portuguese, it should be avoided in C1-level objective writing.

Quick FAQ
How can I make my Portuguese writing sound more formal and less personal, especially at a C1 level?
To achieve a C1 level of objectivity, focus on using impersonal expressions like É preciso and É importante, the formal se passive voice, and impersonal verbs such as haver for existence. Also, incorporate formal research phrases like Observou-se que....
What's the main difference between using se for reflexivity and for objectivity/passivity in Portuguese grammar?
When se is reflexive, it indicates the subject performs an action on itself (Ele lavou-se - He washed himself). When used for objectivity or passivity, se indicates an action without specifying the agent, or that an action is performed on an object, making the sentence impersonal (Vendem-se casas - Houses are sold).
Is it ever acceptable to use ter instead of haver to mean there is/are in formal Portuguese writing?
While ter is very common in informal spoken Portuguese to mean there is/are (Tem muita gente), in formal and academic writing, haver (e.g., Há muita gente) is the correct and preferred choice for expressing existence impersonally.
Besides É preciso and É importante, what are some other common impersonal expressions for formal Portuguese writing?
Other useful impersonal expressions include É necessário (it's necessary), É fundamental (it's fundamental), É evidente que (it's evident that), Convém (it's advisable), and Urge (it's urgent).
Cultural Context
Eu acho or Tem), mastering these impersonal forms is crucial for conveying credibility and authority in any professional written communication. They demonstrate a sophisticated command of the language, signaling a high level of linguistic proficiency and an understanding of the nuances expected in formal discourse.重要な例文 (8)

よくある質問 (6)
É bom que você váと言うのが正解です。
É proibido entrada。定冠詞 'a' がある場合は一致させます。 É proibida a entrada。Analisou-se が好まれます。Vendem-se casas が正解です。ただ、日常会話や簡易的な看板では非常に一般的で意味は通じますが、C1レベルの試験では間違いとされます。
