    17．________ thoroughly，the garden looked more beautiful than ever before．（　　）
    A．CleaningB．Having been cleaned
    C．Having it cleanedD．He had cleaned it

    分析 彻底清扫后，这个花园看上去比以前更漂亮了．

    解答 答案：B
    该题考查非谓语动词作成分，本题首先排除D，因为在一个句子中如果没有并列连词（并列句）和关系词（复合句）连接是不允许存在两套主谓结构的，分析该句句子结构可知____ thoroughly在句中作状语，又因主句主语the garden与clean存在逻辑上的动宾关系，故应使用过去分词或现在分词的被动式作状语，所以排除A和C，由于非谓语动作clean在谓语动作look之前发生，所以应使用现在分词的完成式，故选B．

    点评 考查非谓语作成分时，一定要注意两点：1、非谓语动词在句中作什么成分；2、非谓语动词与逻辑主语存在的关系（主谓或动宾）
