1. Does/Do the king have lots of jewels?

In this question, the subject is the king, which is a singular noun. When the subject is singular in the present simple tense, we use does as the auxiliary verb. Therefore, the correct word is does. The sentence should read: Does the king have lots of jewels? Understanding subject-verb agreement is crucial in English grammar, and this example perfectly illustrates that principle. When the subject is singular, the verb form typically ends in -s or -es. In this case, does is the correct form because it agrees with the singular subject, the king. Choosing the correct auxiliary verb ensures that your sentence is grammatically sound and clear. Think of does as the helper verb for singular subjects in questions. This rule applies consistently across various sentence structures, making it a foundational aspect of English grammar. Mastering this concept allows you to construct accurate and fluent questions in the present simple tense. By selecting does, you show a clear understanding of subject-verb agreement, which is a hallmark of proficient English usage. This question serves as an excellent starting point for understanding the broader applications of auxiliary verbs in different contexts.

2. Did/Do you clean your room yesterday?

The question involves an action that happened in the past (yesterday). Therefore, we use did, which is the past tense auxiliary verb. The correct sentence is: Did you clean your room yesterday? The word yesterday is a clear indicator that the action occurred in the past, making did the appropriate choice. Did is used for all subjects in the past simple tense, simplifying the selection process. Recognizing time indicators like yesterday, last week, or ago helps in identifying the correct tense to use. This question highlights the importance of paying attention to temporal clues within a sentence. Using did correctly conveys that the action of cleaning the room is already completed. This understanding of past tense usage is fundamental to expressing events accurately in English. By choosing did, you demonstrate a grasp of how time affects verb selection in question formation. This knowledge is invaluable for constructing clear and coherent sentences about past events.

3. Do/Does you watch TV in the morning?

The subject in this sentence is you, which takes the auxiliary verb do in questions. Thus, the correct choice is do. The sentence should be: Do you watch TV in the morning? The pronoun you always pairs with do in present simple questions, regardless of whether it refers to a singular or plural person. This rule is consistent and easy to remember, making do the straightforward choice. The question is asking about a habitual action – watching TV in the morning – which is typical of the present simple tense. Choosing do aligns with the grammatical requirement for questions involving the subject you. This example reinforces the concept that certain pronouns have specific auxiliary verb pairings. By selecting do, you demonstrate an understanding of these fundamental rules, which are essential for forming grammatically correct questions. This knowledge is crucial for both spoken and written English, ensuring clear and effective communication.

4. Did/Do Grandma play the sitar?

The question is inquiring about an action that may have happened at some point in the past. Without a specific time reference, but given the general context, did is the more appropriate choice to inquire if Grandma played the sitar at any time in her life. So, the correct sentence is: Did Grandma play the sitar? Did is used to ask about past actions or states, and it fits well here as we are asking about a general past ability or action of Grandma. While there isn't a specific time marker like yesterday, the use of did implies a question about a past activity. This distinguishes it from do, which is used for present habitual actions or general truths. Choosing did allows for a broader interpretation of the question, encompassing any time in the past. This understanding of did as a general past tense auxiliary verb is crucial for formulating questions about past experiences or abilities. By selecting did, you show an awareness of how context and tense work together to create meaning in English questions. This flexibility in using did makes it a valuable tool in your grammatical arsenal.

5. Do/Does Prashant play chess?

The subject in this question is Prashant, which is a singular noun. For singular subjects in the present simple tense, we use does as the auxiliary verb. Therefore, the correct sentence is: Does Prashant play chess? The rule of subject-verb agreement dictates that singular subjects take the auxiliary verb does in questions. Prashant, being a singular noun, aligns perfectly with this rule. This question highlights the importance of identifying the subject and determining its singularity or plurality before choosing the appropriate auxiliary verb. The question is about a general ability or habitual action, making the present simple tense fitting. Selecting does ensures that the question is grammatically correct and clear in its intent. This example reinforces the consistent application of subject-verb agreement in forming questions. By choosing does, you demonstrate a firm understanding of this core grammatical principle, which is vital for accurate English usage.

6. Do/Does they know how to swim?

The subject in this question is they, which is a plural pronoun. Plural subjects in the present simple tense require the auxiliary verb do. Thus, the correct sentence is: Do they know how to swim? The pronoun they consistently pairs with do in present simple questions, making the choice straightforward. This rule is part of the foundational knowledge of subject-verb agreement in English. The question inquires about a general ability, which is characteristic of the present simple tense. Choosing do aligns with the grammatical requirements for questions involving plural subjects. This example reinforces the concept that certain pronouns have specific auxiliary verb pairings. By selecting do, you demonstrate an understanding of these fundamental rules, which are essential for forming grammatically correct questions. This mastery is crucial for both spoken and written English, ensuring clear and effective communication.

In conclusion, mastering the use of do, does, and did is crucial for constructing grammatically correct questions in English. These auxiliary verbs play a vital role in forming questions in the present and past simple tenses. Throughout this exercise, we have explored various examples that highlight the importance of subject-verb agreement and the correct tense usage. Understanding these concepts will significantly enhance your ability to communicate effectively in English. Remember, do and does are used in the present simple tense, with does reserved for singular subjects and do for plural subjects and the pronoun you. Did, on the other hand, is used for all subjects in the past simple tense. These distinctions are fundamental to English grammar and are essential for clear communication. By practicing and internalizing these rules, you will be able to form questions with confidence and accuracy. This mastery will not only improve your written English but also enhance your spoken communication skills. Keep practicing, and you will find that using do, does, and did correctly becomes second nature. This understanding will empower you to express yourself clearly and confidently in a variety of situations. Embracing these grammatical principles will set a strong foundation for your continued language learning journey.
