The Anasazi settlements at Chaco Canyon were built on a spectacular scale with more than 75 carefully engineered structures, of up to 600 rooms each, connected by a complex regional system of roads. 做语法题我们不妨先找到各个选项的硬伤 A were多余 C had been时态错 D and with each改变意思 E each had been 时态和each都用错 很容易得到B正确 然后来说B的结构问题 句子主干settlements were built on a scale. 这里值得一提的是 我以前曾经把每个SC的主干都抽出来 发现核心都是很单一 意思集中表达一个点 其他部分都是修饰 解释说明 伴随等等 这里也是一样的 with结构是做限定修饰成分修饰scale的 什么样的scale呢 告诉你blablabla 后面的connected是修饰structures的 过去分词做后置定语 中间的of up to 600 rooms each也是修饰structures的 夹在中间是为了不引起歧义而清楚的修饰structures 平时我们说的是后应该是这样的 settlements were built on a scale with 75 structures, each of up to 600 rooms. each部分做独立主格.但是无奈后面还有connected 做后置定语 我们就只能把each部分放中间了 不然的话放在句末 ....roads, each of up to 600 rooms还以为each是说road呢
