异想天开

• 拼音: yì xiǎng tiān kāi
• 汉字拆解: 异 = 田 + 共 (different/unusual); 想 = 相 + 心 (appearance + heart — to think/imagine); 天 = 大 + 一 (person + sky — heaven); 开 = 门 + 一 (gate + bar — to open)

含义

To have wildly fanciful or unrealistic ideas; to indulge in flights of fancy; to think the impossible.

Generally pejorative — used to dismiss ideas as impractical or absurdly optimistic. However, in contexts celebrating innovation or entrepreneurship, it may be used with a positive ironic twist to praise bold, unconventional thinking. The phrase invokes the image of a person whose imagination has ascended to heaven, detached from earthly reality.

例句

2. 那个时代的人普遍认为载人登月不过是异想天开，然而短短数十年后它就变成了现实。
3. 批评者认为，在现有技术条件下提出零碳排放城市的规划目标无异于异想天开，缺乏可行性依据。
