passive present participle(现在分词的被动式)
____ some officials, Napoleon inspected his army. A. Followed B. Followed by C. Being followed D. Having been followed by (全国高考)
答案为B。它能否用Being followed by来代替呢？
在书面英语里，上面的 Followed by 可以用 Being followed by 来代替，因为后者无论在语法上还是在惯用法上都是正确的。要知道，过去分词和现在分词的被动式用作状语时，如表示的动作与谓语的动作具有同时性或者表示经常的情况，则在意义上有时并没有什么区别，只是这里的 being 通常省略：
-
Being attracted (= Attracted) by gravity, we'll not fall up into the air. 由于受到地球的引力，我们不会掉入空中。
-
Being asked (= Asked) to give a performance, she couldn't very well refuse. 有人请她表演个节目，她不好拒绝。
-
Being written (= Written) in haste, the composition is full of mistakes. 这篇文章匆促写成，错误很多。
-
He wasn't appointed chairman of the committee, ____ not very popular with all its members. A. considering B. being considered C. to be considered D. having considered iple (分词)
