例314　As we discussed before, it was not until the 19th century that the newspaper became the dominant pre-electronic medium, following in the wake of the pamphlet and the book.

【结构分析】这是个典型的时间强调句，是It is not until sometime that...这种句型，表示直到某个时间才出现某个现象，比如It is not until the end of the century that we can produce a new robot. As we discussed before是个介词短语，承上启下的作用，被强调的成分是the 19th century，后面是真正的强调句that the newspaper became the dominant pre-electronic medium，后面是分词状语following in the wake of the pamphlet and the book。

【亮点回放】此句话的亮点在于强调句套上分词状语following的超级的使用，这种it is not until sometime that...句型很经典，作文写上可以妙笔生辉。

【核心词汇】

dominant　主要额

pre-electronic medium　电子出现前的媒体

the pamphlet　宣传册

【参考译文】正如我们前面讨论的，正是到了十九世纪，报纸才成为电子媒体出现之前的主导性的媒体，报纸是紧跟着宣传册和书出现而出现的。
