Ever since AL Gore invented it, the Internet has been a paradise for those with a creative attitude to facts. Students, for example, commission and sell essays with such ease there that online "paper mills" devoted to this trade are one of the few dotcom business models still thriving. With a few clicks of a mouse, a student can contract out any academic chore to "research" sites such as Gradersaver. com or the Evil House of Cheating.

Passage Five
Anyone who has ever attended a university knows that the quality of lecturers varies greatly. A few are very effective communicators, conveying the substance of their lectures clearly and interestingly and inspiring students to want to know more about the subject. Others produce dull lectures from which the students learn little and which are likely to kill any interest they may have in the subject. Lecturing is a major part of a university lecturer’s job and it would seem reasonable that effectiveness in this task should be a major standard in assessing a lecturer for promotion. However, it is very often the case that far more weight is given to such factors as participation in research, number of publications and even performance of administrative duties. My point of view is that a lecturer’s lecturing should be regularly evaluated and that the best people to carry out this evaluation are those directly on the receiving end.
It co
A. there are great differences among the lecturers as to their quality of teaching
B. quite a lot of teachers can produce the results students desire
C. they must be inspired to learn
D. it is too dull to attend lectures
