以下是引用camuer在2006-10-7 14:56:00的发言:a错在and 后面不能再有 because,and前后应该是两个名词结构,删除because后还得删除charcoal使replaced成为过去分词作定语,a才算对 b错在 in addition to 后面的名词结构从语义上说是主要的,它前面的名词结构是修饰in addition to 后面的名词结构;而整个句子的宾语“the replacement of charcoal by coal for the fuel used in the smelting of iron ore” 在逻辑上是主要的,如此便是矛盾 从Dictionary.com上查到: 7. | in addition to, as well as; besides
|
如此,Over the course of the eighteenth century a tripling in the average output of ironwork was due to the replacement of charcoal by coal for the fuel used in the smelting of iron ore, as well as several improvements in blowing machinery. 还有什么错吗? 请高人指点一二! |
