Everything About Passive Voice - Full English Lesson
TLDRThe video script offers an in-depth exploration of the passive voice in English grammar. It begins by contrasting the passive voice with the active voice, emphasizing that in passive sentences, the subject receives the action rather than performing it. The speaker illustrates how to construct passive sentences using various forms of the verb 'to be' followed by the past participle of the main verb. The script also highlights that passive voice is formed from transitive verbs, which must have an object. It further explains how to create passive sentences in different tenses, including present, past, and future, as well as passive voice questions and negatives. The video also addresses common mistakes to avoid, such as attempting to use intransitive verbs in the passive form. The speaker then delves into the reasons for using the passive voice, including focusing on the object of the sentence, avoiding repetition of the subject, omitting the doer of an action to de-emphasize responsibility or to maintain objectivity, which is particularly important in scientific and academic writing. The summary underscores the importance of the passive voice in maintaining cohesion in writing and its utility in various contexts.
Takeaways
- 📚 **Active Voice vs. Passive Voice**: The active voice has the subject performing the action (e.g., Mary gave me a book), while the passive voice has the subject receiving the action (e.g., I was given a book by Mary).
- 🔄 **Formation of Passive Voice**: The passive voice is formed using a form of the verb 'be' or 'get' followed by the past participle of the main verb (e.g., Books are written by Carlos).
- ❗ **Transitive Verb Requirement**: Only transitive verbs (verbs with an object) can be used in the passive voice because the object becomes the subject in passive sentences.
- 📉 **Passive Voice in Tenses**: Any active voice sentence with a transitive verb can be converted into the passive voice across various tenses, including present, past, future, and perfect tenses.
- 🚫 **Negative and Question Formation**: Passive voice sentences can be made negative by adding 'not' after the 'be' verb and turned into questions by moving the 'be' verb to the beginning.
- 📝 **Academic and Formal Writing**: The passive voice is often used in academic writing, scientific reports, and formal documents to maintain objectivity and focus on the action rather than the performer.
- 🔍 **Focus and Cohesion**: The passive voice can help to focus on the object of the sentence and create cohesion in writing by starting sentences with the subject of interest.
- 🤫 **Avoiding Blame or Unwanted Attention**: Using the passive voice can help to avoid assigning blame or drawing negative attention to the person performing the action in certain contexts.
- 🔄 **Repetition Reduction**: The passive voice can be used to avoid repetitively mentioning the subject, especially when the doer of the action is already clear or not important to the context.
- ❌ **Common Mistakes**: One common mistake is attempting to use the passive voice with intransitive verbs (verbs without an object), which is not grammatically possible.
- 📈 **Cohesion and Coherence**: The passive voice can enhance the flow of information in a text by strategically placing the focus on certain elements to maintain coherence.
Q & A
What is the main difference between active and passive voice?
-In the active voice, the subject of the sentence performs the action of the verb. In the passive voice, the subject of the sentence receives the action of the verb.
How is the passive voice grammatically constructed?
-The passive voice is constructed using a form of the verb 'be' followed by the past participle of the main verb. Optionally, it can include a 'by' phrase indicating the agent performing the action.
What is a transitive verb and why is it important for passive voice construction?
-A transitive verb is a verb that takes an object. It is important for passive voice construction because a verb must have an object to be transformed into the passive voice.
How can you make a sentence in the passive voice negative?
-To make a passive voice sentence negative, you simply insert the word 'not' after the first helping verb (a form of 'be').
What are some reasons for using the passive voice in writing?
-The passive voice can be used to focus on the object of the action, avoid repeating the subject, omit the doer of the action to avoid blame or negative attention, and to maintain objectivity, especially in scientific or formal writing.
How do you form a question in the passive voice?
-To form a question in the passive voice, you move the first helping verb (a form of 'be') to the front of the sentence before the subject. Unlike active voice questions, you do not need to add a new helping verb.
What is the past participle form of a verb and why is it important?
-The past participle is the third form of a verb, often used in perfect tenses and always used in passive constructions. It is important because it signifies the completed action when combined with a form of the verb 'be'.
Can all verbs be used in the passive voice?
-No, only transitive verbs (verbs that take an object) can be used in the passive voice, as the passive voice requires an object to move into the subject position.
What is the function of the 'by' phrase in a passive voice sentence?
-The 'by' phrase in a passive voice sentence indicates the agent performing the action. It is optional and can be omitted if the doer of the action is unknown, irrelevant, or if you want to avoid focusing on the doer.
How does the passive voice help in maintaining objectivity in scientific reports?
-The passive voice helps maintain objectivity in scientific reports by removing the researcher or the subject performing the action from the sentence, allowing the focus to be on the action or the research findings themselves.
What is the structure for forming the passive voice in different tenses?
-The structure for forming the passive voice in different tenses involves using the appropriate form of the verb 'be' that matches the tense, followed by the past participle of the main verb. For example, 'are written' for present passive, 'were written' for past passive, 'are being written' for present progressive passive, etc.
Why might someone avoid using the passive voice in certain contexts?
-Some people might avoid using the passive voice in certain contexts because it can make sentences sound more formal or less direct. Additionally, it can obscure who is performing the action, which may not be desirable in contexts where clarity and directness are important.

📚 Introduction to Active and Passive Voice
This paragraph introduces the concept of active and passive voice in English grammar. It explains that in active voice, the subject performs the action, while in passive voice, the subject receives the action. The paragraph uses the example of 'Mary gave me a book' to illustrate active voice and 'I was given a book by Mary' for passive voice. It also discusses the grammatical structure of passive voice, which requires a form of the verb 'be' plus the past participle of the main verb. Additionally, it clarifies that the 'by' phrase is optional and can be omitted.
🔍 Formation and Use of Passive Voice
The second paragraph delves into how to form the passive voice and when it is appropriate to use it. It emphasizes that passive voice sentences must start with a transitive verb, which is a verb that takes an object. The paragraph provides a step-by-step guide on how to convert active sentences into passive by switching the subject and object positions and using the correct form of 'be' plus the past participle. It also covers how to create passive sentences in different tenses, such as present, past, and future, and how to form negative and interrogative passive sentences.
🚫 Common Mistakes with Passive Voice
This paragraph highlights common mistakes to avoid when using the passive voice. It stresses that passive voice can only be used with transitive verbs, which are verbs that have a direct object. It provides examples of intransitive verbs, like 'happen' and 'sleep', which cannot be used in the passive voice because they do not take an object. The paragraph also demonstrates incorrect attempts to form passive sentences with these verbs, reinforcing the importance of understanding the transitive nature of verbs before attempting to use passive voice.
📝 When to Use Passive Voice
The fourth paragraph discusses various scenarios where passive voice is the preferred grammatical structure. It explains that passive voice is often used to emphasize the object of the sentence, maintain cohesion in writing by avoiding repetition of the subject, and to de-emphasize or omit the doer of an action. Examples given include academic writing, where the focus might be on the action rather than the actor, and situations where the identity of the person performing the action is unknown or unimportant. The paragraph also touches on the use of passive voice in formal or official contexts where direct attribution of actions might be undesirable.
🔑 Passive Voice in Scientific Writing
The final paragraph focuses on the use of passive voice in scientific reports and lab work. It explains that the passive voice is crucial in these contexts to maintain objectivity and to keep the focus on the research findings rather than the researchers themselves. The paragraph contrasts active voice sentences, which highlight the researchers' actions, with passive voice equivalents, which remove the researchers from the sentence and make the text more impersonal and scientific. This approach is deemed essential for presenting research in a neutral and factual manner.
