最后一段:
In common with all mammals, reptiles and birds, their remote ancestors were marine fish and before that various more or less worm-like creatures stretching back, still in the sea, to the primeval bacteria.
看蓝色字体的描述,龟的祖先与爬行动物及鸟类的祖先一样,是海鱼,在海鱼之前,是或多或少像蠕虫的生物,可追溯至仍生活在海里的原始的细菌。
看看本句子分析中用到的阅读技巧
(1)插入语有时以两个逗号隔开,分析句子时,可以先忽略掉他们。在这里reptiles and birds是解释前面的mammal(哺乳动物)。
(2)确定that 的指代,这里that 指的是fish. 所以这里的worm-like creatures(可追溯至 primeval bacteria)是fish的祖先。
所以:龟的演进过程:worm-like creatures (早期primeval bacteria)-> marine fish->tortoises (3)stretching back to.. 修饰creatures
(4)in the sea, 做插入语,阅读时忽略掉,这样才能把stretching back to 里的back 和 to关联起来。
