Sentence completion traps punish answers that mean the right idea but break grammar or the word limit. NO MORE THAN TWO WORDS AND/OR A NUMBER. You copy a phrase that does not fit the gap, add an extra word “for clarity,” or change plural form. Read the whole stem aloud with your answer inside; if it sounds wrong or exceeds the limit, it scores zero.

Why gap-fill punishes form, not just meaning
Instructions cap words and numbers; the stem fixes grammar around the gap. Examiners test whether your answer completes the sentence exactly, not whether you remembered a related phrase nearby.
Completion mistakes that repeat
| Trap | Example | Result |
|---|---|---|
| Extra article | Limit 2: write "the water" | Zero if only "water" needed |
| Wrong form | Gap needs adjective; you copy noun | Zero |
| Long phrase | Copy three words when limit is two | Zero |
Pairs with double-blank gap-fill traps and flow-chart completion traps.
Framework: read stem → proof → fit
1. Read the whole stem
Note grammar before and after the gap, noun slot, verb tense, preposition.
2. Pull exact proof
Underline the phrase in the passage; do not paraphrase yet.
3. Count words
Articles and hyphens count, trim to the instruction cap.
4. Aloud check
Read the completed sentence once; if it jars, the collocation is wrong.
Key takeaways
- Sentence completion scores form and count, not ideas alone.
- Read the stem grammar before hunting the passage.
- Count every word, including articles, against the limit.
- Aloud check catches collocation traps synonyms hide.
