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.
1. D be used for sth被用做....
11.定语从句啊
12.D the chief fuel used 中的 used 是过去分词做定语 可以这样说
the chief fuel which/that is used 表被动 被用做......
1.空格前面的and提示所选项目应当构成与逗号前面并列的结构。如果选B，B是介词结构，前面找不到相应的语法功能一致的结构，所以错。选D，and后面构成一个完整的句子，与前面的句子并列，正确。
2.定语从句的引导词that不能省略。
3.很明显，used in blast furnaces, as well as in glassmaking, blacksmithing, and metalworking是修饰前面的fuel的。如果选B，则是想采纳定语从句的结构，也是可以的，但that后面应当加was，没有was光有that就不对了。
