听力原文: When cars first started appearing on the streets of the world, few people took them seriously. They were toys--playthings for grown men who didn't have much to do. No one thought that the automobile would become the world's most popular means of transportation.

When Henry Ford started selling his Model T in 1908, he changed all that. Ford believed that a car should be low-cost transportation that everyone could afford. So he decided to make such a car. First, he wanted a dependable automobile that wouldn't break down easily. Then he wanted a simple engine that almost anyone could fix.

Ford wanted to sell the car at a low price, so he had to make it at a low cost. Thus he made only one model and designed one color--black.

In 1932, the Duesenberg brothers produced a car that many people think it was the most luxurious automobile ever made--the Duesenberg SJ. Every Duesenberg car was custom-made, so each one was different. But it usually weighed about 7,000 pounds and had a very wide wheelbase--150 inches. It also had a 400 horsepower engine that could drive the huge car from zero to 100 miles per hour in 17 seconds.

The inside was very luxurious, too. It had the best silk, leather, silver and wood. A Dusenberg car was definitely expensive but rich people often felt that they had to own one. Unfortunately, the car cost so much to produce that the company lost money. In 1937, after making only 500 of them, the Duesenbergs stopped producing this kind of cars forever.

(33)

A.The two models of cars.

B.The history of car industry.

C.The development of cars in America.

D.The structure of Duesenberg cars.

听力原文: In preparing a book, I asked several successful executives to tell me what they thought students should study if they wanted to succeed in business. They listed only a few technical subjects accounting and finance, for example. But time and again, these executives identified philosophy as one of the most important areas you can study for learning how to think in a disciplined, analytical, and imaginative way.

The way that philosophy helps you see the world is no less real than its practical benefits to your career. Studying philosophy exposes you to a wide range of problems that you wouldn't meet otherwise. It simply lets you see more of the world. It stretches your imagination. It challenges you to come up with your own answers to tough issues that do not have ready-made solutions.

Studying philosophy helps you to develop insight into some of life's great puzzles and to fashion your own vision of what life is all about. As you go through life, you will be challenged all along the way to make decisions about who you are and what's important to you. Philosophy helps you develop a sense of what life is all about and where you're going.

In fact, Socrates, one of the first great philosophers, thought that philosophy is the single most important element in making our lives worthwhile. "The unexamined life," he said, "is not worth living." In Socrates' mind, at least, philosophy makes it possible for us to control our own destiny.

(33)

A.A senior executive.

B.A professor.

C.A playwright.

D.A science teacher.
