单选题{{B}}Passage Six{{/B}} The sound of gunshots has become an all-too-familiar and unwelcome occurrence in many communities across the nation. When shots ring out, 911 calls from worried citizens may come from a large area. Unfortunately, even with numerous reports, police are often frustrated in their efforts to silence this gunfire because they cannot pinpoint the location of gunshots rapidly. A U.S. Geological Survey (USGS) scientist recognized that sound waves traveling through the air away from a gunshot are basically similar to the sound waves traveling through the ground away from an earthquake. Scientists then have adapted their methods for quickly finding the exact source of an earthquake to the problem of locating gunshots. Field testing of a gunshot--locating system inspired by earthquake technology began in 1995. After only a few weeks of testing and improving the Software, the system was locating many signals that were clearly associated with gunfire. Automatic weapons fire was the easiest to identify because of the regular time interval between individual shots. The system was more sensitive during the night, when there was less background noise from traffic and other urban activity. By the last spring, the system was undergoing final acceptance trials. Captain Jim Granucci of the Redwood City Police Department stated that "even before the system was in use, the number of illegal gunshots declined as word of its existence spread". In this test the gunshot-locating system worked remarkably well, and according to Commander Dominick Peloso of the Menlo Park Police Department, "This system, when fully developed, holds great promise for assisting police in controlling and reducing violent crime." When the results of the test were made public, there was an enthusiastic response from San Francisco Bay area residents, who asked local government officials to implement such systems in their communities. Interest was also expressed by private firms and law enforcement agencies both in California and elsewhere in the nation. Robert Showen, founder of a company that is now marketing a gunshot-locating system, said, "The USGS test demonstrated beyond a doubt that the concept was feasible and could be implemented quickly. Without this test, I would have been hesitant to invest in the development of my product."

单选题Married people live "happily ever after" in fairy tales, but they do so less and less often in real life. I, like many of my friends, got married, divorced, and remarried. I suppose, to some people, I'm a failure. After all, I broke my first solemn promise to "love and cherish until death us do part." But I feel that I'm finally a success. I learned from the mistakes I made in my first marriage. This time around, the ways my husband and I share our free time, make decision, and deal with problems are very different. I learned, first of all, not to be a clinging vine (依赖男子的妇女). In my first marriage, I felt the every moment we spent apart was wasted. If Ray wanted to go out to a bar with his friends to watch a football game, I felt rejected and talked him into staying home. I wouldn't accept an offer to go to a movie or join an exercise class if it meant that Ray would be home alone. I realize now that we were often angry with each other just because we spent too much time together. In contrast, my second husband and I spend some of our free time apart and try to have interests of our own. I have started playing racquetball at a health club, and David sometimes takes off to go to the local auto races with his friends. When we are together, we aren't bored with each other, our separate interests make us more interesting people. I learned not only to be apart sometimes but also to work together when it's time to make decisions. When Ray and I were married, I left all the important decisions to him. He decided how we would spend money, whether we should sell the car or fix it, and where to take a vacation. I know now that I went along with this so that I wouldn't have to take the responsibility when things went wrong. I could always end an argument by saying, "It was your fault!" With my second marriage, I am trying to be a full partner. We ask each other's opinions on major decisions and try to compromise if we disagree. If we make the wrong choice, we're equally guilty. When we rented an apartment, for example, we both had to take the blame for not noticing the drafty windows and the "no pets" clause in our lease. Maybe the most important thing I've learned is to be a grown-up about facing problems. David and I have made a vow to face our troubles like adults. If we're mad at each f other or worried and upset, we say how we feel. Rather than hide behind our own misery, we talk about the problem until we discover how to fix it. Everybody argues or has to deal with the occasional crisis, but Ray and I always reacted like children to these stormy times. I would lock myself in the spare bedroom. Ray would stalk out of the house, slam the door, and race off in the car. Then I would cry and worry till he returned. I wish that my first marriage hadn't been the place where I learned how to make a relationship work, but at least I did learn. I feel better now about being an independent per- son, about making decisions, and about facing problems. My second marriage isn't perfect, but it doesn't have the deep flaws that made the first one fall apart.

单选题{{B}}Directions:{{/B}} Read the following passages, decide on the best one of the choices marked A, B, C, and D for each question or unfinished statement and then mark the corresponding letter with a single bar across the square bracket on the ANSWER SHEET. Passage One Guthrie's contiguity principle offers practical suggestions for how to break habits. One application of the threshold method involves the time young children spend on academic activities. Young children have short attention spans, so the length of time they can sustain work on one activity is limited. Most activities are scheduled to last no longer than 30 to 40 minutes. However, at the start of the school year, attention spans quickly wane and behavior problems often result to apply Guthrie's theory, a teacher might, at the start of the year, limit activities to 15 to 20 minutes. Over the next few weeks the teacher could gradually increase the time students spend working on a single activity. The threshold method also can be applied to teaching printing and handwriting. When children first learn to form letters, their movements are awkward and they lack fine motor coordination. The distances between lines on a page are purposely wide so children can fit the letters into the space. If paper with narrow lines is initially introduced, students' letters would spill over the borders and students might become frustrated. Once students can form letters within the larger borders, they can use paper with smaller borders to help them refine their skills. The fatigue method can be applied when disciplining disruptive students who build paper airplanes and sail them across the room. The teacher can remove the students from the classroom, give them a large stack of paper, and tell them to start making paper airplanes. After the students have made several airplanes, the activity should lose its attraction and paper will become a cue for not building airplanes. Some students continually race around the gym when they first enter their physical education class. To employ the fatigue method, the teacher might decide to have these students continue to run a few more laps after the class has begun. The incompatible response method can be used with students who talk and misbehave in the media center. Reading is incompatible with talking. The media center teacher might ask the students to find interesting books and read them while in the center. Assuming that the students find the books enjoyable, the media center will, over time, become a cue for selecting and reading books rather than for talking with other students. In a social studies class some students regularly fall asleep. The teacher realized that using the board and overhead projector while lecturing was very boring. Soon the teacher began to incorporate other elements into each lesson, such as experiments, videotapes, and debates, in an attempt to involve students and raise their interest in the course.
