| 第3题：{{B}}Text 2{{/B}} Wesleyan President William Haden says the college plans to raise faculty pay.But he says Wesleyan is nothing without students -- "they vote with their feet" -- and the college has no choice but to address their wants and needs. He says technology has been a big part of that, and some recent graduates agree that it’s valuable -- though maybe not essential.Daniel Simmons, a 1999 graduate and also a middle-school teacher, praised the technology program. "If I had gone to another school it wouldn’t have been available to me," he saiD、"It was very convenient and it was top of the line." But as with the faculty, the quality of human instructors is a big concern among Wesleyan alumni. "A、little bit more money should have been put into keeping people," saidEvan Keeling, a 2002 graduate now pursuing a doctorate at the University of VirginiA、He found the quality in the classroom uneven, and, notably, neither he nor theDaniel Simmons came to Wesleyan because of technology. The program was a bonus, not the primary draw. Skinner, the director of admission and financial planning, acknowledged that seems widely true. Prospective students pay more attention to more tangible signs of growth. "It did open some doors for us, but would I have liked to have had a new residence hall or recreational facility I probably would have preferred that," Skinner saiD、His daily. struggle remains filling the freshman class, which may be down 50 people or more this year, due to changes in government financial aid programs and the shuttering of the nursing program. The college still accepts about 80 percent of its applicants, and no longer requires online applications. Haden acknowledges that, with the benefit of hindsight, he might have handled details of how the program was financed differently.But he makes no apologies for taking bold steps which he says have indeed set Wesleyan apart. "We needed to make a statement about our commitment to technology and our belief that it would enhance the quality of education and the preparation of our students," he saiD、"And I’m still believing that." |
B．The technology program provides scholarship for high ability freshmen.
C．The cancel of the nursing program hinders Wesleyan from recruiting students.
D．Online applications are still required if students want to enter Wesleyan.
| 第4题：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’ etters 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 him 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, and debates, in an attempt to involve students and raise their interest in the course. The purpose of this passage is to______.A．inform B．persuade C．debate D．narrate |

| 第5题：Starting with his review of Skinner’s VerbalBehavior, NoamChomsky had led the psycholinguists who argue that man has developed an innate (天生的) capacity for dealing with the linguistic universals common to all languages.Experience and learning then provide only information about the (1) instances of those universal aspects of language which are needed to communicate with other people within a particular language (2) . This linguistic approach (3) the view that language is built upon learned associations between words. What is learned is not strings of words per se (本身), but (4) rules that enable a speaker to (5) an infinite variety of novel sentences. (6) single words are learned as concepts: they do not stand in a one-to-one (7) with the particular thing signified, but (8) all members of a general class. This view of the innate aspect of language learning is at first not readily (9) into existing psychological frameworks and (10) a challenge that has stimulated much thought and new research directions.Chomsky argues that a precondition for language development is the existence of certain principles "intrinsic (原有的) to the mind" that provide invariant structures (11) perceiving, learning and thinking. Language (12) all of these processes; thus its study (13) our theories of knowledge in general. Basic to this model of language is the notion that a child’s learning of language is a kind of theory (14) . It’s thought to be accomplished (15) explicit instruction, (16) of intelligence level, at an early age when he is not capable of other complex (17) or motor achievements, and with relatively little reliable data to go on. (18) , the child constructs a theory of an ideal language which has broad (19) power.Chomsky argues that all children could not develop the same basic theory (20) it not for the innate existence of properties of mental organization which limit the possible properties of languages.
