Read and answer. 阅读短文，回答问题。 My name is Kate. Last Sunday, I visited my friend Amy's home. Her family were preparing for the Mid-Autumn Festival. They made mooncakes in the kitchen. The mooncakes smelled sweet. In the evening, the family sat together in the garden, ate mooncakes and watched the big round moon. It was a warm and happy night. Amy told me that people eat mooncakes and enjoy the full moon at this festival every year. Question: Which festival were Amy's family preparing for? Please write down its English name.
