17、country.=It rained heavily and caused severe flooding in that country.大雨滂沱,造成了那个国家严重的水灾。6.表示方式或伴随现在分词作方式或伴随状语,分词的动作和谓语动词的动作同时发生。表示伴随或方式的现在分词(短语)可与句子一起转换成and连接的并列成分。My father sat in the armchair,glancing through a newspaper.=My father sat in the armchair,and glanced through a newspaper.我父亲坐在扶手椅上浏览报纸。
18、三、现在分词作状语的其他情况1.现在分词作状语时,可以根据意义在其前加上相应的连词(词组)when,while,since,until,once,though,although,as long as,so long as,unless,as if,as though,even if,even though等,表示更加明确的含义。有时这类结构也可视作状语从句的省略。When crossing the street,do be careful.过马路时务必要小心。Dont evaluate childrens marks while having dinner.吃饭时不要评价孩子们的分数。Once
