第一题
首先要知道句子有“,”and后连接也应该是个完整的句子.如果你选了Band后就缺少了谓语动词,构不成句子.而答案ABCD中,只有CD有谓语动词,when和and自然不能重复,所以答案是D
第十一题
定语从句
要是选C 那句子就会出现两个主语,the development 和 new types of fabrics
development led to de production
new types of fabrics既然是两句句子当中怎么能用of 来连接呢?
第十二题
,后句子的结构是主系表,即：charcoal was the chief fuel.至于used in blast furnaces是后置定语来修饰the chief fuel.
