阅读理解Sarah and her best friend, Alex, loved exploring the forest near their neighborhood. One day, while they were exploring through the woods, Sarah stepped upon a shiny rock hidden under a pile of leaves. Excitedly, she said to Alex, "Look at what I found! It looks like a valuable diamond. Promise not to tell anyone! It's just a secret between you and me." Alex nodded, agreeing to keep it a secret.
Later that afternoon, Sarah and Alex met their friend, Emily, in the neighborhood. Unable to control her excitement, Alex told Emily about the treasure Sarah had found. Emily was very curious（好奇的）and wanted to see it, but Sarah quickly stopped them, reminding Alex of their promise. However, Emily's younger brother, Jack, happened to hear their conversation and spread the news to everyone in the neighborhood.
Soon, Sarah's neighbors began to visit her house, hoping to have a look at the mysterious treasure. They knocked on Sarah's door one by one, each asking if they could see it. Sarah and Alex were taken aback by all the attention and didn't know how to deal with the situation.
As the neighbors crowded around, Sarah's mom came out to see what was happening. She gently told the neighbors that the rock they wanted to see was not as special as they thought. It was just a common quartz（石英）Sarah had found in the forest. The neighbors were understanding and soon left with smiles on their faces.
Sarah and Alex learned that some secrets should only be kept between close friends. Sharing secrets with everyone can lead to misunderstandings and unwanted attention. They also realized the importance of trust and honesty in friendship, promising to keep each other's secrets safe in the future.
