Teaching Design Procedure 1.The basic flow chart of teaching Revision → Presentation and exercise →Test for goal → Summary →Post-teaching 2.Teaching situation: Step1: 动词-ed形式作定语 过去分词作定语往往与被修饰的词靠得很紧, 渐渐地成为一个复合词。这种分词叫分词形容词 (the Participle Adjective), 实际上相当于一个单纯的形容词, 除表示“完成”的动作之外, 还表示“被动”的意义。如： spoken English (英语口语)；iced beer (冰冻啤酒)；cooked food (熟食); fried chips (炸土豆条); 【重点和难点】——前置定语和后置定语 1. 不及物动词的过去分词也可作定语，一般作前置定语，不表示被动意义，只强调动作完成。如：fallen leaves落叶；retired workers退休工人；the risen sun升起的太阳。 2. 如果被修饰的词是由every / some / any / no + thing / body / one所构成的复合代词或指示代词those或these等时，即使是单一的过去分词作定语，也要放在被修饰词的后面。如： There is nothing changed here since I left this town. 3. 过去分词短语有时还可用作非限制性定语，相当于一个非限制性定语从句，前后用逗号分开。如： Some of them, born and brought up in rural villages, had never seen a train. 用作前置定语的过去分词通常来自及物动词，带有被动意义和完成意义。例如： We like skating in the frozen lake in the winter. =We like skating in the lake which has been frozen in the winter. How many finished products have you got up to now? =How many products that have been finished have you got up to now? a) 来自不及物动词的过去分词很少能单独用作前置定语，能作这样用的仅限以下几个词，这时仅表示完成意义，不表示被动意义。例如： a retired worker=a worker who has retired an escaped prisoner=a prisoner who has escaped a faded / withered flower=a flower that has faded / withered fallen leaves=leaves that have fallen the risen sun=the sun that has just risen a returned student=a student who has returned vanished treasure=treasure that has vanished b) 用作后置定语的过去分词通常也来自及物动词，表示被动意义和完成意义。这时过去分词相当于一个定语从句。例如： Things seen are better than things heard. =Things which are seen are bet
