The student said, "Let's play a【C3】________on the man. We will hide his shoes, and conceal ourselves behind those bushes." "My young friend," answered the professor, "we should never【C4】________ourselves at the expense of the poor. Put a coin into each shoe, and then we will hide ourselves and watch how the【C5】________affects him. " The student did so, and they placed themselves behind the bushes.

While putting on his coat he【C6】________his foot into one of his shoes; but feeling something hard, he found the coin. Wonder and【C7】________were seen upon his face.

He looked up to the heavens and uttered aloud an【C8】________thanksgiving, in which he spoke of his wife, sick and helpless, and his children without bread, whom from some 【C9】________hand, would save them from dying. The student stood there, 【C10】________affected. He said to the professor, "I feel now the truth of those words, which I never understood before: ' It is more blessed to give than to receive'. "

【C1】
G
由句子结构可知，空格处所填单词和后面的in the path一起作a pair of old shoes的补足语，因此应为动词的分词形式。lying的原形为lie，表示“平放；位于”，此处的意思是“他们看见路上________双旧鞋”，因此答案为G项lying。
【C2】
F
空格位于was后，因此应填入动词的分词形式或形容词。根据空格前面的poor man和后面的in a field close by可知，此处意思是“被雇用在附近的田地里工作的一个穷人”，所以答案选F项employed。
【C3】
N
由空格前的a可知，所填词为可数名词，作play的宾语。由下文内容可知，学生想要把那个穷人的鞋藏起来，然后自己再躲到树丛后面看笑话，因此答案选N项trick。
【C4】
A
由句子结构可知，空格处应填入一个动词作谓语，而且应是动词原形。由空格后面的at the expense of the poor和备选动词原形可知，此处的意思是“我们永远不应该以牺牲穷人为代价来娱乐自己”，所以答案选A项amuse。
【C5】
D
空格位于how引导的宾语从句中，该从句缺少主语，因此应填入名词。由上文可知，教授让学生把两枚硬币放到那个穷人的鞋里，然后他们再躲起来，目的是观察穷人发现硬币后的反应，即他的这个发现会对他有什么影响，因此答案选D项discovery。
【C6】
M
由句子结构可知，此处应填入动词作谓语，而且是动词过去式。由空格后面的his foot into one of his shoes可知，他把脚“伸”进了一只鞋里。slip除了表示“滑倒”的意思外，还可以表示“穿上”，因此M项slipped为答案。
【C7】
B
由句子结构可知，空格处应填入名词，和Wonder。并列作主语。由文义可知，那位穷人发现硬币后感到非常惊讶，下文中的his surprise Was doubled也强调了惊讶，因此答案为B项astonishment。备选的名词中，scale表示“惊恐，惊吓”，但原文并无此意，所以排除。
【C8】
E
空格位于冠词an和名词thanksgiving之间，因此应填入以元音音素开头的形容词，修饰thanks giving。由thanksgiving后的定语从句可知，那位穷人仰望天空，表达了诚挚的感激之情。因为这两枚硬币可以救活他生病的妻子和挨饿的孩子，所以答案选E项earnest。
【C9】
O
空格位于some和名词hand之间，因此应填入形容词，修饰hand。空格前的some表示 “某一个”，因为那位穷人并不知道是谁把硬币放进他的鞋里，所以答案选O项unknown。
【C10】
C
空格所在句结构完整，因此空格处应填入副词，修饰affected。由下句中学生对教授说的话“我从未像现在这样感受到‘给予比索取更幸福’这句话所蕴含的真理”可知，学生被深深地感动了，因此C项deeply为答案。
