PART 1
语法导学
感悟规律 重点难点剖析
感知以下课文原句，完成方框下的小题
◆语法感知
过去分词可以在句中作前置定语和后置定语。如在句___中作后置定语，相当于一个定语从句(which were spoken by his teacher)，在句___________中则作前置定语。
1
2，3，4，5
◆语法精析
过去分词作定语1.意义：及物动词的过去分词作定语往往表示被动和完成；不及物动词的过去分词作定语不表示被动，只表示完成。(1)表示被动和完成a polluted river一条被污染的河流those funded children那些被资助的孩子(2)只表示完成，不表示被动fallen leaves落叶the risen sun升起的太阳
2.位置：单个的过去分词作定语时，通常放在所修饰词的前面；过去分词短语作定语时，通常放在后面，其作用相当于一个定语从句。The student dressed in white is my daughter.＝The student who is dressed in white is my daughter.穿白色衣服的那个学生是我女儿。注意：过去分词作定语和现在分词作定语的区别：(1)语态不同：现在分词表示主动；过去分词表示被动。They will make full use of these recycled materials.他们会充分利用那些可循环利用的材料。The house standing at the corner of the street was built in 2019.矗立在街道角落的那所房子建于2019年。
(2)时间关系上不同：现在分词表示动作正在进行；过去分词表示动作已经完成。
the changing world变化着的世界the changed world改变了的世界
boiling water沸腾的水boiled water开水
