2、Stress Lessen CourseDoreen Sykora is now a juniｏｒat McGill University. She had a difficult time when she first began college. She said, "I was always well prepared fｏｒmy examinations. But I would go in to class to take the exam, ａｎｄ　I would fall apart. I could not answer the questions correctly-even though I knew the answers! I would just blank out because of nervousness ａｎｄ　fear". Histoshi Sakamoto, an anthropology student at Temple University in Tokyo reports similar experiences. These two young students were experiencing something called test anxiety. Because when a student worries ａｎｄ　is stressed about a test, his ｏｒher mind does not work as well as it usually does. The student cannot write ｏｒthink clearly because of the severe tension ａｎｄ　nervousness. Now there are special university courses to help students. In these courses, advisors ａｎｄ　psychologists try to help students by teaching them to manage test anxiety. Such a course helps students learn to live with stress ａｎｄ　not fail because of it. First students take a practice test to measure their worry level. If the tests show that their stress level is high, the students can take a short course to manage the fear. These courses teach students how to relax their bodies. They get training to become calm in very tense situations. By controlling their nervousness, they can let their minds work more easily. Learned information then comes out without difficulty on a test. Doreen Sykora saw immediate results after taking such a course. She now has enthusiasm about the relaxation methods. "Mostly, what I do is imagine myself in a very calm place. Then I imagine myself picking up a pencil. I move slowly ａｎｄ　carefully. I breathe easily ａｎｄ　let all the tension out. With each breath, more worry leaves me. It really works too. My grades have improved greatly! I\'m really doing well at McGill now. This relaxation method works not only on examinations, but it has improved the rest of my life as well". FｏｒHistoshi in Tokyo, the results were much the same. He is enjoying school a lot more ａｎｄ　learning more. What is the similarity between Doreen Sykora ａｎｄ　Hitoshi Sakamoto?【单选题】

A.Students from the same university.

B.Failing in all the examinations.

C.Experiences of test anxiety.

D.Having the same poｏｒstudying habits.

5、An Intelligent CarDriving needs sharp eyes, keen ears, quick brain, ａｎｄ　coordination between hands ａｎｄ　the brain. Many human drivers have all. these ａｎｄ　can control a fast-moving car. But how does an intelligent car control itself ?There is a virtual driver in the smart car. This virtual driver has "eyes," "brains", "hands" ａｎｄ　"feet", too. The mini-cameras on each side of the car are his "eyes," which observe the road ａｎｄ　conditions ahead of it. They watch the traffic to the car\'s left ａｎｄ　right. There is also a highly automatic driving system in the car. It is the built-in computer, which is the virtual driver\'s "brain". His "brain" calculates the speeds of other moving cars near it ａｎｄ　analyzes their positions. Basing on this information, it chooses the right line fｏｒthe intelligent cars, ａｎｄ　gives instructions to the "hands" ａｎｄ　"feets" to act accordingly. In this way, the virtual driver controls his car. What is the virtual driver\'s best advantage? He reacts ______. The mini-cameras are sending images continuously to the "brain". It completes the processing of the images within 100 milliseconds. However, the world\'s best driver at least needs one second to react. Besides, when he takes action, he needs one more second. The virtual driver is really wonderful. He can reduce the accident rate. considerably on expressway. In this case, can we let him have the wheel at any time ａｎｄ　in any place? Experts warn that we cannot do that just yet. His ability to recognize things is still limited. He can now only drive an intelligent car on expressways. 【单选题】

A.rapidly

B.smoothly

C.slowly

D.hardly

正确答案:A

答案解析:空白所在的句子说“他（虚拟司机）……反应”，结合前句内容（什么是虚拟司机最大的优势？）及常识判断A（迅速地）最可能成为答案。
