The–ingformastheAdverbial(动词ing用作状语)现在分词用作状语

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。1.现在分词作时间状语

现在分词作时间状语时，相当于时间状语从句。可在现在分词前加连词“when,while,until”等，使其时间意义更明确。Walkinginthepark,shesawanoldfriend.分析：walk的动作是由其逻辑主语“she”发出，与句子的主语she一致，且构成主动关系，所以用动词-ing形式。＝When/while(shewas)walkinginthepark,shesawanoldfriend.2.现在分词作原因状语

现在分词作原因状语时，可转换为由since,because或as引导的原因状语从句，这类状语多放在句子的前半部分。Beingill，hecouldn'tgotoschool.＝Ashewasill，hecouldn'tgotoschool.3.现在分词作条件状语

现在分词作条件状语时，可转换为if,once或unless等引导的条件状语从句。

Workinghard，you'llmakegreatprogress.＝Ifyouworkhard，you'llmakegreatprogress.4.现在分词作让步状语

现在分词作让步状语时，相当于一个以though/although引导的让步状语从句。Workingorreading，shealwaysdidherbest.＝Whethersheworkedorread，shealwaysdidherbest.5.作方式\伴随\结果状语

现在分词作方式、伴随和结果状语时，说明动作发生的背景和情况。作伴随状语时，表示分词的动作和主句的动作同时发生，此时它可转换成并列句。Usingastick,

thepainterdrewapictureontheground.=Thepainterdrewapictureontheground

byusingastick.
