Most people seem to have more bad dreams early in the night, progressing toward happier ones before awakening, suggesting that they are working through negative feelings generated during the day.

　　【析句】Most people seem to have more bad dreams early in the night 是句子的主干，后面跟了兩個現在分詞結構progressing

　　toward和suggesting that ，都是作伴隨狀語，但是第一個現在分詞結構的邏輯主語是most people，而第二個的邏輯主語是

　　suggesting 前面的所有句子成分。另外，在suggesting 的賓語從句中，過去分詞結構generated during the day 作后置定語，修飾前面的

　　feelings。

　　答案：

　　多數人似乎在入睡初期做更多不好的夢，而在快睡醒前會逐漸做開心一些的夢，這說明人們會在夢里排解白天的負面情緒。
