18、nviting Professor Hudson, a foreign teacher from Beijing University, to give us an English lesson. All of us were deeply impressed on this unforgettable English lesson. The professor began the class with an amazing English story, that attracted our attentions at once. He spoke slowly and clearly so
19、that we could follow her well. Greatly inspiring, most of us took an active part in classroom activities. After class, many students being interviewed spoke high of him. They said that never they experienced such interesting a class. From his lesson, we came to the conclusion what it is not so diffi
20、cult to learn English if we find a good way.答案与解析onby考查介词。句意：这节难忘的英语课给我们留下了深刻的印象。此处是被动语态，应该是“被”，be impressed by “对印象深刻”，故on改为by。thatwhich考查定语从句。该句是非限制性定语从句。story是先行词，指物，定语从句中缺少主语，故用which引导非限制性定语从句。that不能引导非限制性定语从句，故that改成which。attentionsattention考查名词的数。attention“关注”，是不可数名词，没有复数形式，故attentions改为attent
21、ion。attract ones attention “吸引某人的注意”。herhim考查代词。句意：他说得又慢又清楚，以便我们能听懂他的话。根据语境可知follow的宾语与主句的主语He一致，故her改为him。inspiringinspired考查过去分词。句意：深受鼓舞，我们大多数人都积极参加课堂活动。inspire和most of us之间是逻辑上的动宾关系，应用过去分词作原因状语，故inspiring改为inspired。去掉being考查非谓语动词。此处interview和students之间是逻辑上的动宾关系，且非谓语动词interview表已结束的动作，故用过去分词作后置定语，
22、故把being去掉。being done 表过去的正在进行的动作。highhighly考查副词。该处是固定搭配speak highly of“高度评价”。故high改为highly。never后加had考查倒装句。句意：他们说他们从未经历过如此有趣的一节课。结合句意可知宾语从句用过去完成时态，且否定词never位于宾语从句的开头，故主句用部分倒装，故在never后加had。suchso考查副词。such修饰的中心词是名词，而so修饰的中心词是形容词或副词，故such改为so。whatthat考查同位语从句。句意：我们得出的结论是，如果我们找到一个好方法，学习英语并不难。分析句子结构可知conclusion后的句子是同位语从句，从句在句意和结构上均完整， 应用that引导同位语从句，说明名词conclusion的具体内容，故what改为that。
