Sentence Improvement / Phrase Replacement
Overview
Sentence Improvement (also called Phrase Replacement) is a staple of the SBI Clerk Prelims English section. You are given a sentence with an underlined part, and you must decide whether that part is correct as written or needs to be replaced with one of the given alternatives.
This topic tests your command of grammar rules—subject-verb agreement, tense consistency, correct preposition usage, parallelism, and idiomatic expressions. Unlike Error Spotting, where you only identify the error, here you must also select the correct replacement. The skill required is not just detection but correction.
Mastering this topic builds a foundation that helps across the English section—Reading Comprehension options often hinge on similar grammatical distinctions, and Cloze Tests require the same sensitivity to correct phrasing.
Key Concepts
- Subject-Verb Agreement: A singular subject takes a singular verb; a plural subject takes a plural verb. Watch for tricky subjects like "each," "everyone," "neither," and collective nouns.
- Tense Consistency: A sentence should maintain the same tense throughout unless there is a logical reason to shift. Past actions stay in past; present habits stay in present.
- Correct Use of Prepositions: Many verbs and adjectives pair with specific prepositions (e.g., "interested in," "comply with," "afraid of"). Wrong prepositions are a frequent error type.
- Parallelism: Items in a list or comparison must follow the same grammatical structure. "She likes reading, writing, and to swim" is wrong; "reading, writing, and swimming" is correct.
- Pronoun-Antecedent Agreement: Pronouns must match their antecedents in number and gender. "Each student must bring their book" is often tested (correct formal usage: "his or her book").
- Correct Use of Modifiers: Misplaced or dangling modifiers create confusion. "Running quickly, the bus was caught" wrongly suggests the bus was running.
- Idiomatic Expressions: Certain phrases are fixed in English. "Cope up with" is wrong; "cope with" is correct.
- Redundancy and Wordiness: Phrases like "return back," "revert back," or "repeat again" are redundant. The correct forms are simply "return," "revert," and "repeat."
Formulas / Key Facts
| Rule | Wrong | Correct |
|---|---|---|
| Subject-Verb with "each" | Each of the boys were present | Each of the boys was present |

| Preposition with "comply" | comply to the rules | comply with the rules |
| Preposition with "congratulate" | congratulate for his success | congratulate on his success |
| Parallelism in lists | I like to read, writing, and swim | I like reading, writing, and swimming |
| Redundant phrase | return back | return |
| Redundant phrase | free gift | gift |
| Idiom error | cope up with | cope with |
| Idiom error | discuss about | discuss |
| Conditional structure | If I would have known | If I had known |
| Comparative error | more better | better |
Common preposition pairings to memorize: agree with (person), agree to (proposal), consist of, depend on, differ from, prefer X to Y, superior to, inferior to, familiar with, accustomed to.
Worked Examples
Example 1
Sentence: The manager along with his team members have completed the project.
Options: (a) has completed the project (b) have been completing the project (c) having completed the project (d) No improvement
Solution: The subject is "The manager" (singular). The phrase "along with his team members" is additional information and does not make the subject plural. A singular subject requires a singular verb.
Answer: (a) has completed the project
Example 2
Sentence: She prefers tea than coffee in the morning.
Options: (a) tea over coffee (b) tea to coffee (c) tea instead coffee (d) No improvement
Solution: The correct idiom is "prefer X to Y." We do not use "than" or "over" with "prefer."
Answer: (b) tea to coffee
Example 3
Sentence: The report was so lengthy that I could not read it in one go and have to take breaks.
Options: (a) had to take breaks (b) has to take breaks (c) having to take breaks (d) No improvement
Solution: The sentence is in past tense ("was," "could not read"). The phrase "have to" is present tense, breaking consistency. It should be "had to."
Answer: (a) had to take breaks
Common Mistakes
- Ignoring the hidden subject: Students see "team members" near the verb and choose a plural verb, forgetting that "along with," "as well as," "together with," and "in addition to" do not change subject number. → Always identify the true subject before the interrupting phrase.
- Choosing "No improvement" too quickly: When nothing looks obviously wrong, students assume the sentence is correct. → Read the sentence twice; subtle errors like wrong prepositions or redundancy are easy to miss.
- Overcorrecting into awkward phrasing: An option may be grammatically possible but stylistically poor or unidiomatic. → Choose the option that is both correct and natural-sounding.
- Confusing similar prepositions: "Differ from" (comparison) vs. "differ with" (disagree); "agree to" (proposal) vs. "agree with" (person). → Memorize fixed preposition collocations.
- Misreading tense signals: Words like "yesterday," "last year," "since," and "for" indicate specific tenses. → Scan the sentence for time markers before evaluating the verb form.
Quick Reference
- True subject determines verb number—ignore interrupters like "along with" and "as well as."
- "Prefer X to Y"—never "than" or "over."
- "Cope with," "discuss," "emphasize"—no extra prepositions.
- Remove redundancy: "return back" → "return"; "revert back" → "revert."
- Maintain tense consistency—match verbs to time markers.
- When in doubt, read aloud—awkward phrasing often reveals the error.
