第1题

听力原文：Narrator Listen to part of a discussion in a physics class. The professor is dis

cussing Forces. Professor Well, today wed talk about Force and its representation. Student A So what is force？ Professor Well, actually, a force is a push or pull upon an object resulting from the objects interaction with another object. Whenever there is an interaction between two objects, there is a force upon each of the objects. When the interaction ceases, the two objects no longer experience the force. Forces only exist as a result of an interaction. Student A [interrupting] You mean if a force exists, there should be two objects. Am I right？ Professor Thats right. Er, ...For simplicity sake, all forces, interactions, between objects can be placed into two broad categories. One is contact force; the other is force resulting from action-at-a-distance. Student B [ interrupting] Action-at-a-distance？ Professor Yeah, first lets talk about contact force. Contact forces are types of forces in which the two interacting objects are physically in contact with each other. Examples of contact forces include frictional forces, tensional forces, normal forces, air resistance forces, and applied forces. These specific forces will be discussed in more detail later in Lesson 2, as well as in other lessons. Student A Uh...so many forces fall into this category. Then, what is "force resulting from action-at-a-distance"？ Professor Er, ...Action-at-a-distance forces are types of forces in which the two interacting objects are not in physical contact with each other, yet are able to exert a push or pull despite a physical separation. Examples of action-at-a-distance forces include gravitational forces, such as, the sun and planets exert a gravitational pull on each other despite their large spatial separation; even when your feet leave the earth and you are no longer in contact with the earth, there is a gravitational pull between you and the Earth. Next, electric forces, such as, the protons in the nucleus of an atom and the electrons outside the nucleus experience an electrical pull towards each other despite their small spatial separation; and magnetic forces, for example, two magnets can exert a magnetic pull on each other even when separated by a distance of a few centimeters. These specific forces will be discussed in more detail in other lessons. Student B Thats magic! I am quite familiar with the phenomenon you mentioned just now, but before this class, I had no concept of these categories of forces. Student A Er, I know very little about this, too. Professor Actually, forces exist in our daily life. Force is a quantity which is measured using the standard metric unit known as the Newton. A Newton is abbreviated by an "N". To say "10. 0 N" means 10. 0 Newtons of force. Student A [ interrupting] So Newton is the standard metric unit of force？ Professor Thats true. In fact, a force is a vector quantity. As we learned in an earlier unit, a vector quantity is a quantity which has both magnitude and direction. To fully describe the force acting upon an object, you must describe both the magnitude and the direction. Thus, "10 Newtons" is not a full description of the force acting upon an object. In contrast, "10 Newtons downwards" is a complete description of the force acting upon an object; both the magnitude, "10 Newtons", and the direction, "downwards", are given. Student B Uh, thats quite complex and easy to make a mistake. Professor Yeah. ...because a force is a vector which has a direction, it is common to represent forces using diagrams in which a force is represented by an arrow. Such vector diagrams were introduced in an earlier unit and will be used throughout your study of physics. The size of the arrow is reflective of the magnitude of the force and the direction of the arrow reveals the direction which the force is acting. Such diagrams are known as free-body diagrams. Furthermore, because forces are vectors, the influence of an individual force upon an object is often canceled by the influence of another force. For example, the influence of a "20 Newton upward" force acting upon a book is canceled by the influence of a "20 Newton downward" force acting upon the book. In such instances, it is said that the two individual forces "balance each other", meaning there would be no unbalanced force acting upon the book. Student A That sounds interesting. Then, there should be other situations in which two of the individual vector forces cancel each other, the so-called balance, yet a third individual force exists that is not balanced by another force. Professor Thats the point. Next time we will learn how to draw the free-body diagrams, which can help you to understand the situation more easily. Now get ready to answer the questions. You may use your notes to help you answer. 24. What is the discussion mainly about？ 25. How does the professor emphasize his point about force classification？ 26. What are two key factors of force description？ 27. According to the discussion, what forces belong to action-at-a-distance forces？ Listen again to part of the conversation. Then answer the question. Professor Well, actually, a force is a push or pull upon an object resulting from the objects interaction with another object. Whenever there is an interaction between two objects, there is a force upon each of the objects. When the interaction ceases, the two objects no longer experience the force. Forces only exist as a result of an interaction. Student A [Interrupting] You mean if a force exists, there should be two objects. Am I right？ 28. What can be inferred about student A？ Listen again to part of the conversation. Then answer the question. Professor Thats the point, next time we will learn how to draw the free-body diagrams, which can help you to understand the situation more easily. 29. What does the professor mean when she says this？ Professor Thats the point.Narrator Listen to part of a discussion in a physics class. The professor is discussing Forces. Now get ready to answer the questions. You may use your notes to help you answer.

What is the discussion mainly about？

A．The metric unit of forces.

B．The magnitude and direction of various forces.

C．The two kinds of forces and their features.

D．The diagrams of forces.

Tips on Job Search

Marketing You in the Employment Marketplace

You will have to become a salesperson in order to sell yourself in the employment marketplace. And you will have to learn to sell yourself according to the way your customer buys. Meet the customer needs first in order to meet your personal needs. Become customer-driven instead of product-driven.

The first step in the customer-driven marketing process is to understand the market in general and what potential customer needs may be. It does not do any good to have a super product if there is no market for it. There has to be an established need or want in the job market that is satisfied by the product you are intending to sell.

Do you know what your market is？

Who are your potential customers？

What are the specific needs of customers in your market？

The next step in the customer-driven marketing process is to develop your product according to the specific needs of the marketplace. Have you developed your product to meet the specific market needs？ Unfortunately, most students end up taking a major with little or no thought about their intended market.

While it is not the purpose of this guide to go into the entirety of career planning, I will forewarn you that if you are not able to: (1) identify your market, and (2) identify your product in relation to the market needs, you will fail either totally or partially in your job search. So consider yourself forewarned--you need to have a roadmap, an automobile, and a full tank of gas before you start on your trip. Most of us plan our vacations better than we plan our careers. The first step in your job search is to plan the direction you will take toward the type of career you will be seeking. If you have no plan for where you are going, any road will take you there. Don't start off your life blindly or in a random direction. Please make sure you know where you are going before you start your journey of a lifetime.

Prepare to Make an Investment

I have heard literally hundreds of college students talk about how they were going to "coast" in their final year right up to graduation. Your class load may be down, your work load may be lower, and in general, you are finally ready to start living the good life.

Have you forgotten something？ If you don't have a job yet, you are spending fools' gold by coasting through your final year. It's a trap. Many students end up spending their final year hitting all the parties, developing a flourishing romance, or just "taking it easy". And then they talk about how they were "too busy" to look for a job when they come up empty at graduation.

Sorry to crash your party, but until you have landed a job, you still have work to do. In fact, more work than you have done to this point. If you want to be a success in your career, you have to be prepared to make an investment--now!

First of all, you will need to invest your time. You should plan on dedicating a minimum of five hours per week and sometimes as much as fifteen to twenty hours per week to your job search. I know that sounds like a lot of time, but get ready--there is even more, You should also plan to use your Fall, Winter and Spring Breaks for full-time job searching. Your breaks are nonrefundable time that should be banked directly to your job search account. I realize I may be stepping on a lot of Florida party animal toes by recommending job search over Daytona, but this is the time for a reality check. One week in the sun could end up burning you badly at graduation. And don't make excuses that you cannot possibly fit anything else into your "crowded schedule". If you are taking more classes than you need to, drop them. If you are attending more social engagements than you need to, avoid them. Stop volunteering for everything that comes along. You onl

The making of weathervanes devices fixed on the top of buildings to show directions of the

wind is an ancient skill, going back to early Egyptian times. Today the crater is still very much alive in the workshop that Graham Smith has set up. He is one of the few people in the country who make hand-cut weathervanes. Graham's designs are individually created and tailored to the specific requirements of his customers. "That way I can produce a unique per signalized item", he explains. A lot of my customers are women buying presents for their husbands. They want a distinctive gift that represents the man's business or leisure interests."

It's all a far cry from the traditional cock, the most common design for weathervanes.

It's was not a cock but a witch on a broomstick that featured on the first weathervane Graham ever made. Frieds admired his surprise present for his wife and began asking him to make vanes for them. "I realized that when it came to subjects that could be made into them, the possibilities were limitless," he says.(46). He had served an apprenticeship as a precision engineer and had worked in that trade for 15 years when he and his wife, Liz, agreed to swap roles—she went out to work as an architectural assistant and he stayed at home to look after the children and build up the business.

That was five years ago and he has no regrets about his new direction. "My previous work didn't have an artistic element to it, whereas this is exciting and creative," he says. "I really enjoy the design side."(47). He works to very fling detail, aways seeking approval for the design of the silhouette from the customer before proceeding with the hand-cutting.

Graham also keeps plenty of traditional designs in stock, since they prove as popular as the one-offs. "It seems that people are attracted to handcrafting," Graham says. "They welcome the opportunity to acquire something a little bit different"(48).

"I have found my place in the market. People love the individuality and I get a lot of saris faction from seeing a nondescript. shape turn into something almost lifelike," he says(49).

"And nowadays, with more and more people moving to the country, individuals want to put an exclusive finishing touch to their properties. It has been a boost to crafts tike mines(50)."

American and Danish buyers in particular are showing interest. "Pricing," he explains, "depends on the intricacy of the design. "His most recent request was for a curly-coated dog.

Whatever the occasion, Graham can create a gift with a difference.

[A] Graham has become increasingly busy, supplying flat-weathervanes to clients worldwide.

[B] Graham decided to concentrate his efforts on a weathervane business.

[C] Last month, a local school was opened with his galleon ship weathervane hoisted above it.

[D] "For centuries, weathervanes have kept communities in touch with the elements, signaling those shifts in wind direction that bring about changes in the weather," he explains.

[E] Graham has no plans for expansion, as he wants to keep the business as a rural craft.

[F] Graham has now perfected over 100 original designs.
