【特别提醒】 为强调-ing 形式所表达的意义，在-ing 形式短语前可用连词、介词或副词。 ◆“when/while+-ing 形式”强调-ing 形式与谓语动词的动作同时发生。 （如例句 7） ◆“before + -ing 形式”强调-ing 形式在谓语动词所表示的动作之后发生。 （如例句 8） ◆“after+动词的-ing 形式”强调-ing 形式在谓语动词所表示的动作之前发生。 （如例句 9） ◆“on/upon + -ing 形式”表示“一（刚）……就……”。 （如例句 10） ◆“thus + -ing 形式”表示结果。 （如例句 11） ◆“though /although+ -ing 形式”表示让步。 （如例句 12） Ⅱ. 动词的-ing 形式的否定形式 动词的-ing 形式的否定形式为“not+-ing 形式”。 （如例句 13） 【难点点拨】 动词的-ing 形式作状语应该注意的问题： ◆现在分词作状语时，其逻辑主语必须与句子的主语一致，且为主动关系。 ◆独立成分作状语。 常见的有： generally speaking 一般地说； strictly speaking 严格地说； frankly speaking 坦率地说；exactly speaking 确切地说；judging from/by 由……判断出。 （如例句 14） 语法巩固练习 句型转换。(每空一词) 1.
