Understanding Sentence Improvement Questions

Sentence improvement questions test your knowledge of grammar rules like tense, subject-verb agreement, articles, prepositions, etc. You are given a sentence with a part bracketed and asked to choose the best alternative to replace the bracketed part or select 'no improvement' if the original is correct.

Analyzing the Original Sentence

The given sentence is: "There was hardly any traffic and my father told us the history of the place we (is trekking) to."

The bracketed part is "(is trekking)". We need to evaluate if this part is grammatically correct in the context of the entire sentence.

Evaluating the Bracketed Part "(is trekking)"

Let's look at the key elements around the bracketed part:

• The main sentence is in the past tense: "There was hardly any traffic", "my father told us the history".
• The subject of the bracketed part is "we", which is a plural pronoun.
• The verb used is "is trekking". "is" is a singular form of the verb 'to be' in the present tense. "is trekking" is in the present continuous tense.

Issues with "(is trekking)":

• Subject-Verb Agreement: The subject "we" is plural, but the verb "is" is singular. This is a violation of subject-verb agreement. A plural subject needs a plural verb.
• Tense Consistency: The rest of the sentence is in the past tense ("was", "told"). Using the present continuous tense ("is trekking") for an action happening in the past (the trekking must have happened before or concurrently with the father telling the history) creates tense inconsistency.

Therefore, the bracketed part "(is trekking)" is grammatically incorrect and needs improvement.

Examining the Improvement Options

Let's analyze each option provided to find the correct replacement for "(is trekking)".

1. was trekking

   This uses the past continuous tense ("was trekking"). However, the subject is "we" (plural), and "was" is the singular past form of 'to be'. This option fails the subject-verb agreement rule.

2. were trekking

   This uses the past continuous tense ("were trekking"). The subject is "we" (plural), and "were" is the plural past form of 'to be'. This option satisfies both the subject-verb agreement (plural subject "we" with plural verb "were") and the tense consistency (past continuous "were trekking" fits the past context of the sentence). The action of trekking was ongoing in the past when the father told the history.

3. were trek

   This option uses "were", which is the plural past form of 'to be', correctly agreeing with the subject "we". However, "trek" is the base form of the verb. The past continuous tense is formed with "were" + the present participle (verb + -ing), which is "trekking". So, "were trek" is grammatically incorrect for forming a continuous tense.

4. no improvement

   As established earlier, "(is trekking)" is grammatically incorrect due to subject-verb agreement and tense issues. Therefore, improvement is needed.

Concluding the Best Improvement

Based on the analysis, the option that correctly replaces the bracketed part, ensuring proper subject-verb agreement and tense consistency within the sentence, is "were trekking". This forms the past continuous tense "we were trekking", which correctly describes a past action happening over a period.

Additional Information on Verb Tenses and Agreement

Subject-Verb Agreement

A verb must agree in number (singular or plural) with its subject. If the subject is singular, the verb is usually singular (e.g., He walks). If the subject is plural, the verb is usually plural (e.g., They walk). The verb 'to be' is a common source of errors, especially in past tense:

• Singular Past: I was, He was, She was, It was, You were (note: 'you' is always treated as plural for verb agreement)
• Plural Past: We were, They were, You were

Past Continuous Tense

The past continuous tense is formed using 'was' or 'were' (past tense of 'to be') + the present participle (verb + -ing). It is used to describe an action that was ongoing in the past at a specific time or when another action happened. In the given sentence, "we were trekking" describes the ongoing activity that was happening when the father "told" the history.

• Structure: Subject + was/were + Verb-ing
• Example: They were playing when it started raining.
• Example: At 3 PM yesterday, I was studying.

Understanding these basic grammar rules is crucial for sentence improvement tasks.
