题目分析：这篇短文介绍了四则广告，一个是出售一辆自行车，一个是寻求一位英国男性为室友；一个是寻找公文包的寻物启事；一个是捡到了一个公文包的招领启事。
小题1:细节理解题。根据第一则广告可知这是一则出售商品的广告，所以想买自行车可以找张颖；故选A。
小题2:细节理解题。根据第二则广告中Male（男）—English native speaker可知李想找一位以英语为母语的室友来共住一室为的就是提高自己的英语水平；故选B。
小题3:细节判断题。根据第三则广告并没有提到公文包是谁丢的，所以A错误；第四则广告Brown briefcase with some money See: Joseph Hofman in Chemistry Dept（系）可知Hofman发现了一个里面有一些钱的一个棕色公文包；但是他并不一定就是一名老师，很有可能就是一名化学系的学生，所以B项错误；而包里面有钱，但并没有提到有书，所以C项错误；故答案为D。
