网考网参考答案：A
网考网解析：
在时间、条件状语从句中，当从句主语和主句主语一致的时候，可以将从句的主语和be的变化形式省略。但如果从句省略了主语和be的变化形式，而主句主语和从句主语却不一致，这时该状语从句就成了悬垂从句，如；*Although seriously damaged by the earthquake of l917，restoration work has almost brought the cathedral back to its original beauty．(damage和句子主语the restoration work无逻辑关系，而与句子宾语the cathedral是逻辑动宾关系，因此可将本句改为Although it was seriously damaged by the earthquake of 1917，restoration work has almost brought the cathedral back to its original beauty．)尽管这座教堂在1917年的地震中受到很大破坏，但修复工作使其恢复了原有的美丽。 查看试题解析出处>>
