第二题（the chairman of the school board announced a plan to build two new elementary schools during an interview with a local news reporter.)(修改打括号的句子）答案是E.“during an interview with a local news reporter, the chairman of the school board announced a plan to build two new elementary schools”.放在句首是修饰谓语announced 的.如果E这个选项中的”during...reporter"没有打逗号,也是修饰谓语announced 的.如果“during..reporter"放在句子最后,就像原句一样,但用逗号隔开,则属于错误表达.
不知c选项 是如何表达的.无法回答.
然后是第六题（the beaver is the largest rodent in north america, it) has a large, flat, nearly hairless tail, webbed hid feet; and short front legs swith hairy claws.答案是D,"the largest rodent in north america, the beaver".
the beaver是同位语
如果加个being冠词需要改为类指的a 即being a largest rodent in north america,则是现在分词短语作状语
所以在E选项前面加个being不对
