Takeaways

• 😀 The subject is a key term in a sentence, directly related to the verb. It can be a noun, pronoun, or phrase.
• 😀 To identify the subject, always start by finding the verb and ask 'who' or 'what' is performing or receiving the action.
• 😀 The subject can appear before or after the verb in a sentence, but it is essential to relate directly to the verb.
• 😀 The subject is not a person but a term that connects with the verb, and it can have different types (simple, compound, implied).
• 😀 Active voice: The subject performs the action, e.g., 'The teacher makes videos.'
• 😀 Passive voice: The subject receives the action, e.g., 'The videos are made by the teacher.'
• 😀 The agent of the passive voice is the entity performing the action, e.g., 'by the teacher' in 'The videos are made by the teacher.'
• 😀 Transforming an active sentence to passive involves shifting the subject to the receiver of the action and introducing the agent.
• 😀 To verify if a sentence is passive, try reversing it to active and check if the agent becomes the subject.
• 😀 The agent of the passive voice is introduced with prepositions 'por' or 'pelo/pela,' depending on gender and number.
• 😀 Understanding how to identify and use the subject and agent in both active and passive voice enhances sentence construction and analysis skills.

Q & A

What is the main focus of the video?

The main focus of the video is to explain the difference between 'sujeito' (subject) and 'agente da passiva' (agent of the passive) in Portuguese grammar, specifically how they function in sentences.

What is a 'sujeito' in a sentence?

A 'sujeito' (subject) is a term that is essential in a sentence and refers to the part that performs the action or suffers the action, typically related to the verb. It can be a noun or a pronoun.

How can we identify the subject in a sentence?

To identify the subject, first find the verb in the sentence, then ask 'who' or 'what' is performing or receiving the action. The answer to that question is usually the subject.

What are the types of 'sujeito' mentioned in the video?

The types of 'sujeito' mentioned include: sujeito simples (simple subject), sujeito composto (compound subject), sujeito oculto (hidden subject), sujeito indeterminado (indeterminate subject), and oração sem sujeito (sentence without a subject).

What is the importance of the verb in finding the subject?

The verb is crucial because it establishes the relationship with the subject. The subject is the term directly related to the verb, and this relationship helps in identifying the subject in the sentence.

What does it mean when a sentence is in the passive voice?

In the passive voice, the subject receives the action rather than performing it. The focus is on the action being done to the subject, not on who is performing the action.

What is the role of the 'agente da passiva' (agent of the passive)?

The 'agente da passiva' (agent of the passive) is the term that performs the action in a passive voice sentence. It is typically introduced by the preposition 'por' or 'pelo'.

How can you transform a sentence from active to passive voice?

To transform a sentence from active to passive voice, the object of the action becomes the subject, and the subject of the active voice becomes the agent of the passive voice. For example, 'Professor Noslen faz vídeos para o YouTube' becomes 'Vídeos são feitos pelo Professor Noslen'.

What does the term 'agente da passiva' refer to in a passive voice sentence?

In a passive voice sentence, the 'agente da passiva' refers to the term that carries out the action, like the 'by' phrase in English (e.g., 'by the teacher').

Can you give an example of a sentence with a passive subject and its corresponding agent of the passive?

Sure! An example is 'Os erros foram corrigidos pelo professor' ('The errors were corrected by the teacher'). In this case, 'os erros' is the passive subject, and 'pelo professor' is the agent of the passive.
