Think about the purpose of a descriptive paragraph:
* To create a vivid picture of a pebble in the reader's mind.
* To appeal to the senses (sight, touch, sound, etc.).
* To provide specific details about the pebble's appearance, texture, or other features.
Now let's consider some examples:
Good Supporting Sentences:
* Its surface was smooth and worn, like polished glass.
* Tiny, glittering flecks of quartz sparkled in the sunlight.
* The pebble felt cool and heavy in my hand.
* It was the size and shape of a small, lopsided egg.
A Sentence that Wouldn't Be a Good Supporting Sentence:
* Pebbles are often found on beaches. This is a general statement about pebbles, not a specific detail about *this* pebble.
Key Takeaway: The best supporting sentences will focus on sensory details and unique characteristics of the specific pebble you're describing.
