网友回答
(答案→)teacher前面加a。
解析：
试题分析: 今天上午来自北京大学的Smith教授给我们上了一堂英语课。教授用一个幽默的英文故事开场，他说话清晰缓慢以便我们都能够听清楚。受到极大鼓励的我们都积极的参与课堂活动，从他的课上我们意识到了只要找到好的方法英语并不难学。
【小题1】1 foreign teacher from Beijing University.。此处是名词短语做Professor Smith的同位语，teacher是单数可数名词，故前面加a。
【小题2】This morning Professor Smith, …… who gave us an English lesson.。根据结构判断gave的主语是Professor Smith，而不是定语从句，所以去掉who。
【小题3】All of us were deep impressed by this unforgettable lesson。deep意思是“深的”，指具体的深度，deeply指抽象意义“深深地”，而此处指我们对他的课印象深刻，故把deep改为deeply。
【小题4】The professor began the class in an amusing English story。固定短语：begin …..with“以……开始”，故把in改为with。
【小题5】which attracted their attention at once。根据语境可知此处指吸引了我们的注意力，故把their改为our。
【小题6】Greatly inspiring, most of us took an active part in classroom activities.。动词inspire和句子主语之间是被动关系，故改为过去分词inspired。
【小题7】many students were spoke highly of him。根据上文可知本句指学生对老师评价很高，用主动形式，把were去掉。
【小题8】hey said never before have they experienced such interesting a class.在本句中主句是一般过去时，那么宾语从句应该受主句时态的影响用过去完成时，所以把have改为had。
【小题9】….. they experienced such interesting a class.。such用来修饰名词，结构为：such+ 形容词+（冠词）+名词；而so一般用来修饰形容词或者副词，修饰单数名词时结构为：so +形容词+a /an +单数名词，所以把such改为so。
【小题10】it is not so difficulty to learn English well。系动词is后用形容词做表语，故把difficulty改为difficult。
