英语短语describe as的核心含义是“把……描述为……；将……说成是……”，用于表达对某人、某事或某物的性质、特征、状态等的描述或评价。
`describe + 宾语（sb/sth） + as + 宾语补足语（n./adj./doing/done等）`
其中：
宾语：被描述的人或物（如人、事物、情况等）；
as后的成分：是对宾语的定性或评价，可以是名词、形容词、现在分词（doing）或过去分词（done）。
He described his new job as a "dream come true".
（他把新工作描述为“梦想成真”。）
The book was described as a masterpiece by critics.
（评论家把这本书描述为杰作。）

（她把这场音乐会描述为“令人惊叹且难忘”。）

常常用被动结构be described as，强调“被描述为……”，更突出评价的客观性：
The city is often described as the "Paris of the East".
（这座城市常被称为“东方巴黎”。）
The novel has been described as a classic of modern literature.
（这部小说被描述为现代文学的经典。）
as后的成分：需是名词性或形容词性结构，不能直接接从句（如不能说 describe it as that it’s good，应改为 describe it as good）；
与“regard as”的区别：`describe as`更强调“具体描述”（通过细节说明特征），而`regard as`更侧重“主观看待”（认为某人/物属于某类）。例如：
She described him as tall with brown hair（具体描述外貌）；
She regarded him as a friend（主观认定关系）。
总结：`describe as`是“描述+定性”的核心短语，用于清晰表达对人/物的评价或特征描述，是英语中高频使用的表达。
