（单词翻译:单击）

　　现在分词的完成被动式表示分词的动作发生在谓语的行为之前，且动作由逻辑主语所承受(即与逻辑主语是被动关系)。

　　【例如】

　　Having been given such a good chance, he planned to work hard.

　　Having been experimented several times, this new product will be putsintosmass production.

　　All the compositionsshavingsbeen written and collected, the teacher dismissed¹ the students.
