复杂的定语从句的拆分和理解 例13

例13　Experts suggest that speech stages are reached at a constant age and promoted gradually according to the talents of humans, but there are cases where speech has started late in a child who eventually turns out to be of high IQ and has great talents in solving mathematical and physical problems.

【结构分析】转折前半句的主干是Experts suggest...，后面加上宾语从句that...，这个宾语从句的主语是speech stages，动词有两个分别是are reached和promoted, promoted后面加上介词短语according to the talents of humans做状语，转折后半句的主干是there are cases，后面是个定语从句where speech has started late in a child，后面再加上定语从句who eventually turns out to be of high IQ and has great talents in solving mathematical and physical problems，其中最后这个定语从句中in solving mathematical and physical problems这个介词短语修饰前面的名词。

【亮点回放】此句话的亮点在于but后面是连环定语从句，非常复杂，有who引导，有where引导，很有气势，连环定语从句也可以用于作文。

【核心词汇】

speech stages　语言阶段

at a constant age　按照年龄循序渐进

promoted gradually according to　成正比

turn out to be of high IQ　表现很高的智商

solve mathematical and physical problems　解决数学和物理问题

【参考译文】专家说语言阶段按照年龄的增加循序渐进的提高，而且语言能力与人类的语言天分成正比，但是有些个别情况是语言发育晚的孩子反而有很高的智商，而且有很高的智商解决数学和物理问题。
