81. In a survey conducted for eCornell, the DL division of Cornell University, less than a third of the respondents expected the quality of the online course to be as good as the classroom course.

　　主干：... less than a third... expected the quality... to be as good

　　解析：句中两个逗号间的内容（the DL division of Cornell University）是插入成分，用以解释说明eCornell。本句是简单句，谓语部分用了复合宾语（动词+宾语+宾补结构），不定式to be...在句中作宾语quality 的补语。as good as...是同级比较结构。

　　译文：在为康奈尔在线（康奈尔大学远程教育学院）做的一次调查中，只有不到三分之一的受访者预计在线课程的质量与在校课程的一样好。
