比
RuleA + bi + B + adjective: "A is more ... than B." The bi-phrase comes before the adjective.
Curiosity
English puts the comparison after the adjective: "taller than him." Where does Chinese put it?
Intuition
bi is a scale that weighs A against B. You set the thing compared (bi + B) before the adjective first, then state the result with the adjective.
Visualization
Reorder the English-like [I][tall][than him] into Chinese [I][bi][him][tall]. The bi-phrase moves before the adjective.
English-like (comparison after adjective)
我subject高adjective比他standard
Chinese order (bi-phrase before adjective)
我subject比比 (comparison)他standard高adjective
Essence
A bi B + adjective. Put the degree after the adjective: gao yidian (a little), gao de duo (much). Do not put hen or feichang before the adjective (A bi B hen gao is wrong). The negative is A meiyou B + adjective ("A is not as ... as B").
Examples
我比他高。
I am taller than him.
今天比昨天冷一点。
Today is a little colder than yesterday.
这个比那个便宜得多。
This is much cheaper than that.
