低于 dīyú to be lower than
怎么记住“低于”: 低 low + 于 at = to be lower than.
汉字
用法
- 低于 (dīyú) is a formal comparative verb meaning 'to be lower than,' used mainly with numbers and statistics: 低于平均水平 (dīyú píngjūn shuǐpíng) - below the average level.
- It's the written/technical counterpart of the everyday construction 比…低 (bǐ…dī); 低于 is common in reports, data, and specifications, while 比…低 is more natural in casual speech.
- 低于 directly takes its object after it (低于100元), unlike 比…低 which needs 比 before the comparison term - mixing the two patterns is a common learner error.
例句
- 这个工作需要不低于300美金。 Zhège gōngzuò xūyào bù dīyú 300měijīn.No less than three hundred dollars was needed for the work.
