Witnessing time难句剖析学案

牛津译林版  选修九  Unit 2

1. The Western or Roman alphabet is a Greek invention, as is the marathon, which is a long distance race named for a Greek messenger who ran from Marathon to Athens to report a victory at the battle of Marathon in 490 BC.西方字母表或罗马字母表就是希腊人的发明，正如马拉松比赛一样。马拉松比赛是一项长跑运动，是为纪念一位希腊信使而设立的。公元前490年，他从马拉松平原一直跑到雅典去报告马拉松战役的胜利。

剖析：1）as is the marathon 是非限制性定语从句，修饰先行词a Greek invention；

2）which is. . . in 490 BC是非限制性定语从句，修饰先行词the marathon；

3）named for. . . in 490 BC是过去分词短语作定语，修饰a long distance race；

4）who ran. . . in 490 BC是限制性定语从句，修饰先行词a Greek messenger；

5）to report a victory at the battle of Marathon in 490 BC是不定式短语作目的状语。

拓展：分析句子结构时要从前往后层层分解，找出关键词是根本。

剖析：1）in order to引导的是目的状语；
