Sentence Improvement — SSC CGL English
Sentence improvement is error spotting with a twist: instead of finding the error, you choose the correction — and one option is always "No improvement". That last option is a psychological trap. Roughly one in five answers is "No improvement", but anxious candidates fix sentences that were never broken. The discipline: name the rule being violated before touching the options. No rule, no change.
1. What SSC actually asks
Tier 1: 2–3 Q · Tier 2: 5–8 Q. A sentence with a bracketed/underlined segment, three rewrites of that segment, and "No improvement". Tier 2 versions use longer segments where two things change at once — one option fixes the grammar but breaks the meaning, and one fixes both.
2. The eight error zones (scan in this order)
| # | Zone | Trigger words | Classic fix |
|---|---|---|---|
| 1 | Tense sequence | if, since, after, by the time | If I (would have) known → had known |
| 2 | Subject–verb agreement | one of, each, the committee, news | One of my friends (are) → is |
| 3 | Conjunction pairs | no sooner, hardly, scarcely, not only | No sooner… (when) → than |
| 4 | Fixed prepositions | senior, junior, prefer, superior | senior (than) → senior to |
| 5 | Gerund vs infinitive | deny, avoid, enjoy, look forward to | denied (to steal) → denied stealing |
| 6 | Comparatives | than, of the two, any other | better than (any) player → any other player |
| 7 | Parallelism & modifiers | lists, "-ing" openers | likes reading and (to swim) → swimming |
| 8 | Indirect speech | asked, told, said | asked me (that why) → asked me why |
3. The pairings you must know cold
Conjunction pairs (breaking the pair is the #1 Tier-1 question):
- No sooner … than (never when)
- Hardly / Scarcely … when (never than)
- Not only … but also · Neither … nor · Both … and · Lest … should
Latin comparatives take to, not than: senior to, junior to, superior to, inferior to, prior to, prefer X to Y.
Gerund-only verbs: avoid, deny, enjoy, mind, suggest, finish, admit + -ing. Also every "to" that is a preposition: look forward to hearing, accustomed to working, addicted to playing.
4. The method
- Read the full sentence — the error zone is often outside the bracket's first word (a since early in the sentence forces a tense later).
- Name the rule. Scan the eight zones; say the violated rule to yourself. If no zone fires after a full scan → No improvement.
- Prefer the minimal fix. The correct option changes the least while fixing the named rule. An option that rewrites everything usually smuggles in a new error or shifts the meaning.
- Re-read with the fix inserted. It must sound complete — right tense, right pairing, no dangling modifier.
5. Solved PYQ-style examples
Q1. No sooner did the bell ring (when) the students rushed out. Solution. "No sooner" pairs only with than. (Had the sentence begun with "Hardly", the pair would be "when".)
Q2. If I (would have known) about the meeting, I would have attended it. Solution. Third conditional: the if-clause takes past perfect, never "would have" → had known. The "would have" belongs in the main clause only.
Q3. She is senior (than most of) her colleagues. Solution. Latin comparative: senior to → "senior to most of her colleagues."
Q4. He denied (to have stolen) the wallet. Solution. Deny takes a gerund → having stolen.
Q5. I look forward (to hearing) from you. Solution. No improvement. Here to is a preposition, so the gerund is correct — the tempting "to hear" would be the error. This is the trap in reverse.
6. Exam protocol
- Name the violated rule before reading options; options are written to suggest errors that don't exist.
- If two options both fix the grammar, choose the one that preserves the original meaning and changes less.
- Never pick an option you can't attach a rule to — "sounds better" is how the distractors are designed to win.
- Expect "No improvement" to be right roughly 15–20% of the time; picking it should feel like a positive finding (full scan, no rule fired), not a surrender.
- 30–40 seconds per question; sentence improvement is a volume topic in Tier 2 — bank the time for Reading Comprehension.
