Sentence Improvement — Study Notes
Overview
Sentence Improvement is a core English grammar topic in SSC MTS Paper 1 that tests your ability to identify and correct grammatical, structural, and usage errors in sentences. You are given a sentence with an underlined portion, followed by four alternatives (typically A, B, C, and "No improvement needed"). Your task is to select the option that makes the sentence grammatically correct and contextually appropriate.
This topic typically carries 2–3 questions in the exam and requires strong command over grammar rules, tense usage, subject-verb agreement, prepositions, and idiomatic expressions. The key skill is recognizing subtle errors that make a sentence awkward or incorrect. Unlike Spot the Error where you identify the mistake, here you must actively choose the best correction. Mastering this topic improves not just your score but also your overall sentence construction ability, which helps in other sections like Fill in the Blanks and Reading Comprehension.
Success requires two things: knowing grammar rules cold and developing an ear for what "sounds right" in standard English. Regular practice trains both these skills simultaneously.
Key Concepts
- **Subject-Verb Agreement**: The verb must match the subject in number (singular/plural) and person. Collective nouns, indefinite pronouns, and compound subjects are common trap areas.
- **Tense Consistency**: Maintain logical tense throughout a sentence unless the timeline genuinely changes. Mixing past and present incorrectly is a frequent error tested.
- **Preposition Usage**: Many verbs and adjectives require specific prepositions. "Different from" not "different than," "consists of" not "consists in" — these fixed combinations appear often.
- **Articles (a, an, the)**: Correct article usage depends on whether the noun is countable/uncountable, specific/general, and whether it's mentioned for the first time.
- **Comparative and Superlative Forms**: Use comparative (better, more intelligent) for two items and superlative (best, most intelligent) for three or more. Double comparatives like "more better" are always wrong.
- **Parallelism**: Items in a list or comparison must follow the same grammatical structure. "He likes swimming, running, and to cycle" is incorrect; it should be "swimming, running, and cycling."
- **Word Order**: Standard English follows Subject-Verb-Object order in declarative sentences. Misplaced modifiers create confusion about what is being described.
- **Redundancy and Wordiness**: Phrases like "past history," "advance planning," or "revert back" contain unnecessary repetition. The improved version eliminates the redundant word.
Formulas / Key Facts
1. **Subject-Verb Agreement Rule**: Singular subject takes singular verb; plural subject takes plural verb. "Each of the boys **is** ready" (not are).
2. **Common Incorrect Prepositions**: Married to (not with), differ from (not with), comprised of (not comprised with), listen to (not listen).
3. **Article Rules**: Use "a" before consonant sounds, "an" before vowel sounds, "the" for specific/previously mentioned items, no article for general plural or uncountable nouns.
4. **Tense Markers**: By + time = Perfect tense; since/for = Present Perfect; when = Simple Past; while = Continuous tense.
5. **Pronoun-Antecedent Agreement**: A pronoun must agree in number with its antecedent. "Everyone must bring **their** book" is increasingly accepted but "his or her book" is formally correct.
6. **Conditional Sentence Types**: First conditional (will + base verb), Second conditional (would + base verb), Third conditional (would have + past participle).
7. **Common Redundant Phrases**: Return back → return; continue on → continue; added bonus → bonus; end result → result; circle around → circle.
8. **Double Negative Rule**: Two negatives make a positive in English. "I don't have nothing" is incorrect; use "I don't have anything" or "I have nothing."
Worked Examples
**Example 1**: *The teacher asked the students to* **complete their homework before the deadline expires**.
**Options**: A) before the deadline expired B) before the deadline will expire C) before the deadline expire D) No improvement needed
**Solution**: The main verb "asked" is in past tense, but "expires" is present tense, creating tense inconsistency. Since the asking happened in the past and the deadline was also in the past relative to now, we need past tense.
**Answer**: A) before the deadline expired
---
**Example 2**: *She is* **more smarter** *than her sister*.
**Options**: A) most smarter B) smarter C) more smart D) No improvement needed
**Solution**: "Smarter" is already the comparative form of "smart." Adding "more" creates a double comparative, which is grammatically incorrect. The word "more" is used with adjectives that don't have -er forms (like "more intelligent"), but "smart" becomes "smarter."
**Answer**: B) smarter
---
**Example 3**: *The committee* **have decided** *to postpone the meeting*.
**Options**: A) has decided B) are decided C) was decided D) No improvement needed
**Solution**: "Committee" is a collective noun treated as singular in British and formal American English. It represents one unit making a decision collectively. Therefore, it takes a singular verb "has" not plural "have."
**Answer**: A) has decided
Common Mistakes
1. **Ignoring "No improvement needed" option**: Students often assume every sentence must have an error. Sometimes the original sentence is correct, and you must confidently select "No improvement needed." Read carefully before rejecting the original.
2. **Choosing based on "sounds good" without grammar check**: An option might sound natural but be grammatically wrong (or vice versa). Always verify against specific grammar rules. "Between you and I" sounds fine to many people but is incorrect; it should be "between you and me."
3. **Overlooking subject-verb agreement with intervening phrases**: In "The box of chocolates **are** on the table," students focus on "chocolates" (plural) but the subject is "box" (singular), so it should be "is." Ignore prepositional phrases between subject and verb.
4. **Confusing similar-sounding prepositions**: "Comprised of" is wrong; correct is "composed of" or simply "comprises." "Different than" is American informal; formal and British usage is "different from." Learn the standard combinations.
5. **Failing to maintain parallelism in lists**: When you see a list like "He enjoys reading, to write, and painting," spot the break in parallel structure. All three should be gerunds: "reading, writing, and painting." Check that all items match grammatically.
Quick Reference
- Always check subject-verb agreement first — it's the most frequently tested error.
- Maintain consistent tense unless meaning requires a shift.
- Eliminate redundant words: "revert back" → "revert," "past experience" → "experience."
- Match pronouns to their antecedents in number and gender.
- Use "between" for two items, "among" for three or more.
- Trust grammar rules over "what sounds right" — colloquial speech often differs from written standard English.
