Usage of 比
The character 比 is primarily used as a comparative preposition meaning "than" or "compared to". It connects two elements to express a difference in degree, quantity, or quality. For example, "这个手机比那个便宜" means "This phone is cheaper than that one."
Common Patterns
- Subject + 比 + object + adjective: This is the most common structure to compare two things.
- 比 + number + measure word + noun: To express difference in quantity or age, e.g., "他比我大三岁" (He is three years older than me).
Nuances
比 always introduces the standard of comparison and is followed by an adjective or verb phrase. It cannot stand alone without a comparison target. When used with verbs, it often appears in structures like "跑得比我快" (runs faster than me).
Common Collocations
Avoiding Confusion
Do not confuse 比 as a preposition with 比赛 (competition) or 比较 (comparison) as nouns or verbs. Also, 比 is not used for equality comparisons; for equal comparisons, words like 一样 (yíyàng) are used instead.
