题目

though typically about two inches taller now than XX years ago,today"s people ..请帮我分析下
Though typically about two inches taller now than 140 years ago,today's people apparently reached their limit in the early 1960s 这个句子,前面的分词作状语,省略的—省略的内容“today's people are” .分词作状语,后面的动词不是得发生形式变化吗?是不是把being省略了.是不是原来应该是Though typically (being)about two inches taller now than 140 years ago这样..把being也省略了?

答案

though 2 inches taller than last year, he has potential to grow even taller.
though 20% higher than the last quarter, the sales volume will not reach the peak until X'mas.

这两句的结构和你提问中的完全一样,主句的时态根据语境各自不同.动词是否发生形式变化也完全取决于想要表达的意思.

从句中并不需要 being 的成分,也不是被省略的.
