Understanding Subject-Verb Agreement for Sentence Improvement
The question asks us to identify the best way to improve the bracketed part "(has attained)" in the sentence: "Great personalities (has attained) their heights by doing things differently". This involves checking for correct subject-verb agreement.
Analyzing the Original Sentence
Let's break down the sentence:
- Subject: "Great personalities"
- Verb Phrase: "(has attained)"
- Tense: Present Perfect (indicated by the auxiliary verb 'has' and the past participle 'attained')
The subject "Great personalities" is a plural noun. In the present perfect tense, the auxiliary verb must agree in number with the subject. The auxiliary verb for plural subjects is 'have', while the auxiliary verb for singular subjects (and 'I' and 'you') is 'has'.
The sentence uses "has attained". 'Has' is a singular auxiliary verb. This creates a subject-verb agreement error because the plural subject "Great personalities" is used with the singular auxiliary "has".
Subject-Verb Agreement Rules in Present Perfect
For the present perfect tense, the structure is: Subject + Auxiliary Verb (have/has) + Past Participle of the main verb.
- If the subject is singular (he, she, it, a singular noun), use 'has'.
- If the subject is plural (we, you, they, a plural noun), use 'have'.
- If the subject is 'I' or 'you', use 'have'.
In our sentence, the subject is "Great personalities", which is plural. Therefore, the correct auxiliary verb should be 'have'. The past participle of the verb 'attain' is 'attained', which is correctly used.
The correct verb phrase should be "have attained".
Evaluating the Options for Sentence Improvement
Let's examine the given alternatives:
- have attained: This option uses the plural auxiliary verb 'have' with the past participle 'attained'. This correctly agrees with the plural subject "Great personalities" in the present perfect tense.
- have attain: This option uses the plural auxiliary verb 'have' but follows it with the base form of the verb 'attain' instead of the required past participle 'attained' for the present perfect tense. This is grammatically incorrect.
- have attaining: This option uses the plural auxiliary verb 'have' but follows it with the present participle 'attaining'. This form ('have' + -ing verb) is used in the present perfect continuous tense (e.g., 'have been attaining'), not the simple present perfect. This is grammatically incorrect.
- no improvement: The original sentence "Great personalities has attained..." contains a subject-verb agreement error ('has' with a plural subject). Therefore, improvement is needed.
Conclusion on Sentence Correction
Based on the rules of subject-verb agreement in the present perfect tense, the correct verb form for the plural subject "Great personalities" is "have attained". Option 1 provides this correct form, effectively improving the sentence.
Revision Table: Subject-Verb Agreement Basics
| Subject Type | Auxiliary Verb (Present Perfect) | Example Sentence |
|---|---|---|
| Singular Noun / He / She / It | has | He has attained success. |
| Plural Noun / We / You / They | have | They have attained success. |
| I / You | have | I have attained success. You have attained success. |
Additional Information on Verb Forms and Sentence Improvement
Understanding different verb forms and how they combine with auxiliary verbs is crucial for sentence correction and achieving grammatical accuracy. The present perfect tense describes actions that happened at an indefinite time before now or started in the past and continue to the present.
The main verb 'attain' has several forms:
- Base Form: attain
- Past Simple: attained
- Past Participle: attained
- Present Participle: attaining
For the present perfect, we always use the past participle form after 'have' or 'has'. In this case, 'attained' is the correct past participle to use with 'have'.
Errors in subject-verb agreement are common. Always identify the true subject of the sentence and ensure the verb form matches its number (singular or plural).
