Draw a conclusion: “过去分词与它相关联的名词时是被动关系”Step 3Ask the students to observe the position of the past participle when it is attributive. Draw a conclusion: “单个分词作名词的定语时，其位置在名词前；分词以短语形式出现则其位置在名词后”Step 4Ask the students to analyse the sentence components of participles or participles in three examples.(1) Most people just use the shortened name: “the United Kingdom” or “the UK”.
