一个句子中有三个动词的情况，通常被称为并列句或复合句，其中包含两个或更多的简单句，并通过并列连词（如and, but, or等）连接。以下是一些例子：
1. She is dancing ballet, singing songs, and playing the piano.
2. He got home, took off his shoes, and lay down on the sofa.
3. I ate breakfast, brushed my teeth, and went to school.
4. The dog chased its tail, barked loudly, and wagged its tail.
5. They ran, jumped, and cheered at the game.
在这些例子中，每个例子都包含了至少三个动词，它们通过逗号分隔，构成了并列结构。这种句子结构在叙述中很常见，用于描述一系列相关的动作或事件。
