The smaller and newer universities do not 70 the staff or equipment to carry out the 71 research projects possible in larger institutions. 72 most experts agree that some research activity is 73 to keep the staff and their students in 74 with the latest developments in their subjects. Most students attend a university mainly to 75 the knowledge needed for their chosen 76 . Educationists believe that this aim should not be the 77 one. Universities have always aimed to produce men and women 78 judgment and wisdom as well as knowledge. For this reason, they 79 students to meet others with differing 80 and to read widely to 81 their understanding in many fields of study. 82 a secondary school course, a student should be interested enough in a subject to enjoy gaining knowledge for its own 83 .

What does the author mean by saying “ the 21st century equivalent of being caught naked(Lines 34, Para. 2)？ A) People39。t notice it. Only when it39。s important to reveal yourself to friends, family and lovers in stages, at appropriate times. But few boundaries remain. The digital bread crumbs(碎屑 ) you leave everywhere make it easy for strangers to reconstruct who you are, where you are and what you like. In some cases, a simple Google search can reveal what you think. Like it or not, increasingly we live in a world where you simply cannot keep a secret. The key question is： does that matter?

Only an aggressive research and development program might find ways of breaking our dependence on fossil fuels or dealing with it. The trouble with the global warming debate is that it has bee a moral problem when it39。t. But it hasn39。s living standards. With modest growth, energy use and greenhouse emissions more than double by 2050. No government will adopt rigid restrictions on economic growth and personal freedom (limits on electricity usage, driving and travel) that might cut back global warming. Still, politicians want to show they39。s too low, because societies that grow richer use more energy. We need economic growth unless we condemn the world39。t do much about it. From 20xx to 2050, the world39。t do much about it. We will argue over it and may even, as a nation, make some fairly solemnsounding mitments to avoid it. But the more dramatic and meaningful these mitments seem, the less likely they are to be observed. Al Gore calls global warming an ―inconvenient truth‖, as if merely recognizing it could put us on a path to a solution.
