21、 and he was followed by a group of his students.老师走进教室，后面跟着一群学生。三、学习过去分词作定语时，注意过去分词所在的位置单独的过去分词作定语常常置于其所修饰的名词前You should improve your spoken English.过去分词短语作定语常常置于其所修饰的名词后He is a teacher respectedby all his students.不及物动词的过去分词作定语当与其所修饰的名词构成逻辑上的动宾关系时，必须在该动词后使用必要的介词He is the student laughed at by all people just now.专心-专注-专业
