Because of these changes, the face of education and access to education are different today. The most obvious change is that there are different things to teach. In fact, there is much more to t

3、each. Learning and research have increased greatly in the past century. Great advances in science mean that there is much more information to teach. Some of the ideas of the past were wrong, so the content of books is different. For example, in a beginning biology class today, more than 70% of the i

4、nformation that students learn today was not known twenty years ago. Thats an important reason for change! As scientists learn more, there will be more for students to learn. Another reason for changes in education is that there are new teaching tools. For centuries, schools had no books. The teache

5、rs gave by lessons explaining ideas to students. Today teachers and students use books, including e-books. They also use technology. For example, many of them use computers, video, and on-line communication. There are even electronic classrooms. Through interactive instructional television networks

6、(IITV), a teacher can teach students in different places. Their IITV classrooms use radio signals or satellite communication to carry the communication from tower to tower. There are differences between the traditional classroom and the IITV classroom, of course. However, most of these differences a

7、re easy to overcome. Perhaps one student wants to have a private conversation with the teacher. If teacher and student talk on the IITV network, there is no privacy. Everyone else in the class can hear what they say. Therefore, their conversation, must happen over telephone lines or through electron

8、ic mail (e-mail). No one really knows how this change in students ability to talk privately with a teacher changes the educational experience. Some students decide not to talk to the teacher because it cannot happen naturally after class. She could send an e-mail message or decide not to bother the

9、teacher. This lack of personal contact with the teacher is just one potential problem. Another is that the students in different classroom places cannot speak with one another as easily. One solution to this drawback is the class chat room. To facilitate students conversation about a topic, the teac

10、her can set up an Internet chat room or a bulletin board. A number of general topics are posted, and the students can write in their thoughts on the topic. Some students are shy of using these kinds of communication tools. Perhaps they dont have access to the equipment, or maybe they dont know how t

11、o get to a chat room on the Internet. Communication among students is possible, but it takes place through a medium that is different from voices in a classroom. On the other hand, there are great advantages to teaching through IITV. Great numbers of students can “attend“ the class. Education is not

12、 limited to those who are near a university. Another advantage is the ability to show things to students. Every IITV classroom has a padcam TM. This special camera focuses on any picture, book page, or object that the teacher wants the students to see. The camera focuses on a rectanglethe pad. A tea

13、cher can put a picture, for example, on the pad of the padcam TM. The padcam has a zoom lens. Therefore, the teacher can focus on tiny things in the picture and make them much bigger than life. Art history teachers and anthropologists love the padcam TM. They use it to make their lessons more intere

14、sting. They can show details with ease. Computer programs such as Power Point connect easily to the electronic equipment in interactive television. Therefore, the presentation of ideas can happen quite well. The teacher can put the main ideas on the screen, so the students know what the main ideas o

15、f the lesson are. Another advantage is the ability to include videos in lessons. It is easy to show movies or parts of cinemas. Furthermore, there can be a videotape record of every lesson. A student who misses a class can watch the tape. Then he knows exactly what happened in class! Students change

16、 from generation to generation. The students of today learn in different ways from their grandparents forty years ago or their parents twenty years ago. Todays students grew up under different conditions. Most of them have always had electricity. Perhaps they have always had television. They grew up

17、 with technology. The things that a person has always known seem natural to him or her. Of course, there is always change. Changes in society happen slowly, one at a time. Therefore, people usually accept changes as natural. For older people, the changes today seem to happen very fast. They find it

18、more difficult to keep up with the changes. Younger students are used to a faster speed of living. They accept the speed as something natural. The new technology, the change in personality of students, and the changes in content all affect education today. Schools look different, teachers do differe

19、nt kinds of teaching, and students learn different things. It is impossible to tell how education will change in the next generation.

Now most of these prehistoric desert people (36) 1the countryside throughout the year. You might think that theyre wandering aimlessly.

Myers is the founder of Auburn Universitys

39、Institute for Biological Detection Systems, the main task of which is to chase the ultimate in detection devices-an artificial nose. For now, the subject of their research is little more than a stack of gleaming chips tucked away in a laboratory drawer. But soon, such a tool could be hanging form th

40、e belts of police, arson (纵火) investigators and food-safety inspectors. The technology that they are working on would suggest quite reasonable that, within three to five years, well have some workable sensors ready to use. Such devices might find wide use in places that attract terrorists. Police co

41、uld detect drugs, bodies and bombs hidden in cars, while food inspectors could easily test food and water for contamination. The implications for revolutionary advances in public safety and the food industry are astonishing. But so, too, are the possibilities for abuse: Such machines could determine

42、 whether a woman is ovulating(排卵), without a physical exam-or even her knowledge. One of the traditional protectors of American liberty is that it has been impossible to search everyone. Thats getting not to be the case. Artificial biosensors created at Auburn work totally differently from anything

43、ever seen before. Aromascan, for example, is a desktop machine based on a bank of chips sensitive to specific chemicals that evaporate into the air. As air is sucked into the machine, chemicals pass over the sensor surfaces and produce changes in the electrical current flowing through them. Those cu

44、rrent changes are logged into a computer that sorts out odors based on their electrical signatures. Myers says they expect to load a single fingernail-size chip with thousands of odor receptors(感受器), enough to create a sensor thats nearly as sensitive as a dogs nose. （分数：88.50）(1).Which of the follo

45、wing is within the capacity of the artificial nose being developed?（分数：17.70）A.Performing physical examinations.B.Locating places which attract terrorists.C.Detecting drugs and water contamination.D.Monitoring food processing.(2).A potential problem which might be caused by the use of an artificial

46、nose is_.（分数：17.70）A.negligence of public safetyB.an abuse of personal freedomC.a hazard to physical healthD.a threat to individual privacy(3).The word “logged“ (Line 4, Para. 5) most probably means “_“.（分数：17.70）A.presetB.enteredC.processedD.simulated(4).To produce artificial noses for practical us

47、e, it is essential_.（分数：17.70）A.to develop microchips with thousands of odor receptorsB.to invent chips sensitive to various chemicalsC.to design a computer program to sort out smellsD.to find chemicals that can alter the electrical current passing through(5).The authors attitude towards Larry Myers

48、 work is_.（分数：17.70）A.cautiousB.approvingC.suspiciousD.overenthusiasticNot all decisions are alike. Nor is every decision made in the same manner. Although some actions you undertake derive their basis from newly made decisions, there are other instances when decision-making does not really take place. The latter, according to Deacon and Firebaugh, may involve routine, programmed, impulsive or intuitive action. When you wake up in the mo
