Presentation I. The present participle as the adverbial Read the sentences below and try to identify what kind of adverbial the V-ing functions as. 1. Hearing the news, they immediately set off for Shanghai. 2. Being tired, I stopped to have a rest. 3. Working harder at English,you will make greater progress. 4. Feeling exhausted, they still kept running. 5. She lay on the grass, staring at the sky for a long time. 现在分词作状语（修饰动词）时, 可表时间、原因、条件、方式、伴随、让步等情况,其逻辑主语必须是句子的主语，构成主动关系，其作用相当于状语从句或并列句。 1. 作时间状语(when, while, until) eg. Seeing the police, he made a run for the exit. 一看到警察，他就朝出口奔去。 （分析：see的动作是由其逻辑主语“he”发出，与句子的主语he一致，且构成主动关系，所以用动词-ing形式。） _______________________, he made a run for the exit. 2.作原因状语（since, because或as） eg. Being ill, he didn’t go to school yesterday. Because___________, he didn’t go to school yesterday. 3.作条件状语(if, once或unless) Working hard at your lessons, you will succeed. If ___________________________, you will succeed. Pay attention 1) 动词-ing形式作状语时,其逻辑主语必须与句子的主语一致. l Looking out of the window, the garden was beautiful. l Looking out of the window, we found the garden beautiful. Pay attention 2)当--ing表示的动作发生在谓语动词之前时,应使用完成式: having done.否定式在前加not。 1. Having finished his homework, he rushed out to play basketball. 2.Not having studied his lessons very hard, he rushed out to play basketball. Pay attention 3) V–ing 用于某些固定搭配中,表示说话人的态度;观点等,如:generally speaking, frankly speaking, honestly speaking, judging by/from（据...判断）, considering/seeing(考虑到）, supposing（假设）等 __________ his accent, he must be from the north. 根据他的口语判断，他一定来自北方。 Exercises 1.______________(try) many times before, he still couldn't overcome the difficulties. 2.His car broke down on the way, thus ________ (cause) him to be late for the election. 3.Tom walked away, __________ (complain) about the cold weather. 4.There are many goods, ________ (range) from food and drink to some electronic products. 5.________ (walk) in the street with his dog following him, he felt really free and pleased. 6. ____________ (not know) his address, I couldn't go to see him yesterday.
