Normally not such model answer, just remind yourself the "tense" is present tense, 4 photos means each photo around 8 words to describe....i will write like:
"Today, I go to Happy Farm with my parents. We take a lot of photos inside the garden. I see some children throw stones to harm (or hurt) the ducks. I am very angry and stop them all at once."
Sam goes to Happy Farm with his parents. He looks at the corn, carrots, strawberries and watermelons. Two children throw stones into the pond. Sam is angry and tells them it hurts the ducks. The children say sorry and leave.
