I’ll never forget one special day at the beach. My mom and dad took me there to go beachcombing (赶海). There were many shells on the beach. I picked up the shells and put them in my bucket. Suddenly, I found a blue crab in a crack (缝隙) between two rocks. I used long tongs (钳子) to pick it up. “I caught it! What a big one!” I shouted like I had found treasure (宝物).
