Seeing from the top, the city looks beautiful. Looking down from the top, I saw a beautiful city. Looked down from the top, I saw a beautiful city. 记忆口诀： 分词作状语，主语是问题。前后两动作，共用一主语。 主语找出后，再来判关系。主动用-ing，被动用-ed。 语法串讲·融会贯通 易错点突破：过去分词与现在分词作状语的区别 比较维度 过去分词 (done) 现在分词 (doing) 与主语关系 被动（动宾关系） 主动（主谓关系） 例句对比 Used for a long time, the book looks old. Using the book, I find it very useful. 句意 由于被用了很久，书看起来很旧。 使用这本书时，我发现它很有用。 ________ (ask) why she was late, Wendy went red in the face.
