Subject + Verb + 得 + 比 + B + Adjective
比 can function as a preposition introducing the standard of comparison before the verb or adjective. In this pattern, 比 marks the thing being compared against. For example, 他跑得比我快 means "He runs faster than me," where 比我 sets up the comparison before the adjective 快.
