⚖️ The Same Paragraph: Run-On vs Controlled
| Run-on version (AO6 Band 2) | Controlled version (AO6 Band 4) |
|---|---|
| "The old stadium was falling apart weeds pushed through the concrete the seats were cracked some were missing altogether nobody had cared for years and now it was too late." Why it fails: No sentence demarcation across a 42-word stretch. The ideas are vivid but entirely unseparated. AO6 Band 2: some punctuation used but boundaries not controlled. |
"The old stadium was falling apart. Weeds pushed through the concrete; the seats were cracked, some missing altogether. Nobody had cared for years — and now it was too late." Why it works: full stop, semicolon, comma and dash all do different work. Three sentences, three different punctuation choices. AO6 Band 4: varied and inventive, mostly correct. |

What is a sentence fragment?
<strong>A sentence fragment</strong> is a group of words punctuated as a sentence but missing a key part — usually no main verb, or no subject, or no complete thought.<br><br><strong>Fragment:</strong> <em>“Running as fast as possible. Until she could run no more.”</em><br><strong>Fixed:</strong> <em>“She ran as fast as possible, until she could run no more.”</em><br><br><strong>Test:</strong> does the sentence have (1) a subject, (2) a main verb, (3) a complete meaning? If any is missing — it is a fragment.
What is a run-on sentence?
<strong>A run-on sentence</strong> is when two or more complete sentences are written without any punctuation between them — no full stop, no semicolon, no conjunction.<br><br><strong>Run-on:</strong> <em>“The alarm rang nobody moved.”</em><br><strong>Fixed:</strong> <em>“The alarm rang. Nobody moved.”</em><br><em>or: “The alarm rang; nobody moved.”</em><br><br><strong>Quick test:</strong> can you put a full stop anywhere in the middle and still have two complete sentences on each side? If yes — you have a run-on.
