Discovering Useful Structures
分词作状语
一、分词有形容词副词的特征，作定语或作状语
二、分词作状语时相当于状语从句
①分词作时间状语
相当于一个由when，while或after等引导的时间状语从句
②分词作原因状语
相当于一个由as，since或because等引导的原因状语从句
③分词作条件状语
相当于一个由if，once或unless等引导的条件状语从句
④分词作让步状语
相当于一个由though，although或even if，even though等引导的让步状语从句
⑤分词作方式或伴随状语
若有连词as if，就转换为as if引导的方式状语从句；若无连词，则转换为并列结构。
三、现在分词表主动，过去分词表被动。
四、状语从句中若主语和主句主语一致，则可换成分词作状语
状语从句换分词作状语三步曲：
1.看从句主语和主句主语是否一致；（大前提，一致能换，不一致不能换）
2.若一致找从句谓语动词是什么。核心的谓语动词，助动词不算
3.判断主语和从句谓语关系，主动用现在分词，被动用过去分词

在英语中，谓语只能是动词，不是谓语的动词全部改成非谓语动词。独立主格结构在句中作状语，多用于书面语。 独立主格结构本身不是句子，在句子中作状语，表时间、原因、条件、伴随、目的及状态等。

Henry Norman Bethune was a Canadian doctor with a very creative mind and a determination to help people. As a small boy, he became very interested in medicine and decided to become a doctor. After he graduated from medical college in 1916, Bethune worked as a doctor in England, the US, and Canada. He reinvented or redesigned over 10 medical instruments to make them more useful. In 1938, Bethune left for China, after he heard that many people were dying in the war. Despite the difficult situation, Dr Bethune did whatever he could to assist the Chinese people. He helped to organise hospitals, taught doctors and nurses, and showed people how to give first aid. Sadly, Dr Bethune passed away in November the following year and was buried in Shijiazhuang. After Dr Bethune’s death, Chairman Mao Zedong wrote an article in memory of him, in which he praised Dr Bethune as a hero to be remembered in China.
