听力原文： Good evening, welcome to the first meeting of our spring cycling season. It's a pleasure to see so many new faces here. I certainly hope that most of you will soon feel right at home with our group and bicycling will be a regular hobby for you and a part of your physical routine. Some of you may not realize that the State of New Jersey offers ample opportunities for bicyclists of all abilities. We've rolling countryside, miles of beaches, lovely hills and mountains and valleys and thousands of miles of roads. Beginners will find the shore suitable for their needs while expert riders will find that the steep trails of the region offer a challenge to their skill. In addition, New Jersey is rich in historical interest. The state abounds in colonial architecture, battlefields of the revolution and other historic sites important in the early history of the country, most are carefully preserved and restored. We organize tours to a variety of places nearly every weekend. Next Saturday's tour will relatively be a easy one. Interested cyclists will meet at 8 a. m. in the parking lot at the corner of Hamilton Street and College Avenue. The minimum time of this tour is about six hours. Each new rider must team up with an experienced rider. You can pick up a map of Saturday's tour at the information table before you leave this evening.
What is the purpose of the talk？
A．To encourage people to participate in a club activity.
B．To introduce a new kind of bicycle.
C．To inform. the beginning cyclists about New Jersey's traffic law.
D．To warn tourists about bicycling on the roadways.
Directions: You will hear three dialogues or monologues. Before listening to each one, you will have 5 seconds to read each of the questions which accompany it. While listening, answer each question by choosing A, B, C or D. After listening, you will have 10 seconds to check your answer to each question. You will hear each piece ONLY ONCE.
听力原文： Little by little, Americans are turning to solar power, tapping the strength of the sun for energy.
Solar energy is only in its infancy, however, sunlight has already been used for heating or cooling homes and office buildings in the sunny south. Experts say all signs point to the birth of the solar energy industry. Right now, an increasing number of companies are selling solar collector panels to heat and cool homes or to heat water. The glass and metal panels cost from ＄ 100 to more than ＄ 500 each, and the three or four bedroom homes usually require a dozen or more. They look like sandwiches, or very narrow flower boxes, 3 to 6 feet in width, 8 to 10 feet long, and 4 to 8 inches thick. They are usually placed in rooftops. Nobody knows how many have been sold, and in addition, many people have built their own units. It has been estimated that solar power equipment will be a ＄ 1.3 billion industry by 1995, and more a million homes will use sunlight for heat, air conditioning or to generate electricity, both in the cities and in countryside.
What do we learn about the use of solar energy in the USA？
A．It is very well established.
B．It is relatively new.
C．It is found in one million homes.
D．It is being rapidly expanded.

The creative shaping process of a technologist's mind can be seen in nearly every artifact that exists. For example, in designing a diesel engine, a technologist might impress individual ways of nonverbal thinking on the machine by continually using an intuitive sense of rightness and fitness. What would be the shape of the combustion chamber? Where the valves should be placed? Should it have a long or short piston? Such questions have a range of answers that are supplied by experience, by physical requirements, by limitations of available space, and not least by a sense of form. Some decisions, such as wall thickness and pin diameter, may depend on scientific calculations, but the nonscientific component of design remains primary.
Design courses, then should be an essential element in engineering curricula. Nonverbal thinking, a central mechanism in engineering design, involves perceptions, the stock-in-trade of the artist, not the scientist. Because perceptive processes are not assumed to entail "hard thinking", non- verbal thought is sometimes seen as a primitive stage in the development of cognitive processes and inferior to verbal or mathematical thought. But it is paradoxical that when the staff of the Historic American Engineering Record wished to have drawings made of machines and isometric views of industrial processes for its historical record of American engineering, the only college students with the requisite abilities were not engineering students, but rather students attending architectural schools.
If courses in design, which in a strongly analytical engineering curriculum provide the back- ground required for practical problem-solving, are not provided, we can expect to encounter silly but costly errors occurring in advanced engineering systems. For example, early models of high-speed railroad cars loaded with sophisticated controls were unable to operate in a snowstorm because a fan sucked snow into the electrical system. Absurd random failures that plague automatic control systems are not merely trivial aberrations; they are a reflection of the chaos that results when design is assumed to be primarily a problem in mathematics.
The author write this passage mainly to______.
A．introduce a new idea.
B．stress the importance of nonverbal thinking.
C．criticize the education for omitting an important part of knowledge.
D．propose a suggestion.
