有一读者问： 我在一本小册子里见到这样一段英文：
(1)The Forest of Steles in Guangzhou, embodying the full technique of southern gardening, presents the cream created by China's poets and calligraphers. Adding to it are marvellous spectacles on the Baiyun Mountain and along the Pearl River, also the new look of the South.
如何分析最后一句？ Adding to it起什么作用？
上述例（1）中的最后一句是一倒装句，但这种倒装句大都已成一固定句型，故不可还原为Marvellous spectacles...are adding to it。再如：
(2)Facing the gate is a screen wall.
(3)Covering much of the earth's surface is a blanket of water.
(4)Heading the procession was the military band.
(5)Attending the evening party were 700 students from 15 Beijing universities and colleges.
这种固定句型中常用的现在分词除上述各句中的adding, facing, covering, heading, attending外，还有standing, sitting, lying等。但在当代英语中，有不少人在活用这种句型，尤其在新闻体裁中，几乎可以用任何现在分词，如：
(6)Pioneering the reform are some enterprises in Beijing, Shanghai, Harbin and Qingdao.
(7)Throwing the hammer is champion Willion Anderson, a shepherd from the Highlands of Scotland.
在这种倒装结构中，一般主语较长，故须置于句末。现在分词须置于句首，它与其他的助动词be构成动词短语，作谓语用。
