In English grammar, subject-verb agreement plays a crucial role in determining the correct form of the verb. In the sentence ‘Yuki is a student and (study/studies/studied) hard every day,’ the verb ‘studies’ is the correct choice. In this article, we will explain why ‘studies’ is the appropriate option and explore the rule behind subject-verb agreement.
Understanding Subject-Verb Agreement
Subject-verb agreement refers to the requirement that the subject and verb in a sentence must agree in number (singular or plural) and person (first, second, or third). For example, in the present simple tense, when the subject is singular and in the third person (like ‘Yuki’), the verb typically takes the -s form (e.g., ‘studies’).
In the given sentence, ‘Yuki’ is a singular subject, and since we are talking about a present-day habit or routine, we need to use the present simple tense with the appropriate verb form for a singular third-person subject.
Why ‘studies’ is the Correct Choice
In the sentence ‘Yuki is a student and (study/studies/studied) hard every day,’ the correct verb form is ‘studies.’ This is because ‘Yuki’ is a singular subject, and when using the present simple tense, the verb must take the -s form for third-person singular subjects. Therefore, the correct sentence is: ‘Yuki is a student and studies hard every day.’
The other options, ‘study’ and ‘studied,’ are not correct in this case. ‘Study’ is used with plural subjects or first and second person subjects (e.g., ‘I study,’ ‘They study’), and ‘studied’ is the past tense form, which does not fit the context of an action that occurs regularly or in the present.
Present Simple Tense and Daily Routines
The present simple tense is commonly used to describe habits, routines, and facts that are generally true. Since the sentence refers to Yuki’s daily routine of studying, the present simple tense is appropriate, and the verb should agree with the singular subject ‘Yuki.’
Examples of using the present simple tense with third-person singular subjects include: ‘She reads books every morning,’ ‘He works in the office,’ and ‘It rains often in this area.’
Other Examples of Subject-Verb Agreement
Here are some more examples of subject-verb agreement in the present simple tense:
- ‘He plays tennis on weekends.’
- ‘The dog runs in the park every day.’
- ‘She enjoys reading books.’
In each of these examples, the verb agrees with the third-person singular subject, following the rule of adding -s to the verb.
Summary
In conclusion, the correct verb form in the sentence ‘Yuki is a student and (study/studies/studied) hard every day’ is ‘studies’ because it agrees with the singular third-person subject ‘Yuki.’ The present simple tense is used to describe daily routines, and for third-person singular subjects, the verb takes the -s form. Understanding subject-verb agreement is essential for mastering English grammar, especially when forming sentences in the present simple tense.
