Key:
1. D。根据第二段作者给出的“explanation”（解释）可将答案定位到第三段、第四段，可以看出K博士在第一堂课就向学生声明每堂课都会有一个谎言，因此选择D选项。从后文第六段可以看出，K博士说谎的目的是为了吸引学生的注意力，不是因为他喜欢说谎，排除A。从第六段第二句可以看出，刚开始的谎言是比较“obvious”（明显的），排除B。C选项文中没有提到。
2. C。从第七段可以看出，随着课程的进展，每节课的谎言变得越来越隐晦了（“increasingly subtle”），越来越难被发现了，因此选择C选项，同时排除D选项。从第十段可以看出（“…there was no lie…”，并不是每节课都有一个谎言的，排除A选项。从第四段第二句话“Your job, as students, among other things…”可以看出，学生们的任务是在做其他事情的同时要找出哪一句话说谎了，没有提及找谎话是最重要的事情，B选项错误。
3. D。从第六段“…focus our attention…”和第九段“…work in study groups…”可以看出利用“Lie of the Day”，K博士促使学生们集中注意力并进行小组学习，因此选择D选项。其他选项均在文中找不到明显线索。
4. A。根据题干中“most technically difficult lecture”将答案范围定位在第十段之后。根据对第十一段到十三段的理解，在学生们怎么也找不到本堂课的谎言的时候，K博士告诉学生们其实他第一节课的时候说谎了——不是每节课都有谎言，因此选择A选项，同时排除D选项。从第十二段“Exhausted from…”可以看出，学生们感到筋疲力尽，但并没有感到乏味，排除B选项。C选项错在时间。
5. B。文章讲述了作者最喜爱的教授K博士的故事，K博士在第一堂课的时候告诉学生们每节课都会有一个谎言，学生们没有人怀疑这句话，但实际上最难的一节课上并没有谎言，作者也意识到了不能盲目地相信接收到的信息，结合文章的主要内容，选择B选项。A、D选项文中没有提到。针对C选项，K博士使用了让学生找他讲课中的错误这种方法促进学生学习，使课堂更有趣，但这不是最后一段所体现的，所以排除。

III. Language study
1. As the quarter progressed, the Lie of the Day became more subtle, and many ended up slipping past most students unnoticed until a particularly alert person stopped the lecture to flag it.
释义：随着学期的推进，“本日谎言”开始变得更隐晦了，很多都溜过去没被学生注意到，直到有个别特别警觉的人打断讲座，把谎言指出来。
分析：本句中的as表示“随着……”，end up doing …表示“以……告终”。Flag在这里的意思是“指出”。

2 .... but what made Dr K’s technique genius was, during the most technically difficult lecture of the entire quarter, there was no lie.
释义：K博士的手法的过人之处在于，在整个学期中专业最难的课上，他都没有说谎。
分析：本句中的what引导名词性从句作主语，what引导名词性从句相当于名词词组，可以用作句子的主语、宾语或表语等。例如：What he said was perfectly true.

3. Exhausted from having our best theories shot down, we nodded.
释义：我们因为最好的理论被推翻而筋疲力尽，只能点头同意。
分析：Exhausted from ...为过去分词短语作状语，表示原因，该分词短语的主语和主句的主语一致。例如：Not knowing what to do, I telephoned the police.
shoot down意思是“彻底推翻(be very critical of sb’s ideas, opinions, etc)”。例如：All his theories have been shot down.

4. My previous lecture was completely on the level.
释义：我之前的这个讲座是完全真实的（没有谎言）。
分析：本句中的on the level意为“诚实的（地），坦率的（地）”。例如：My story was completely on the level.
