Concern with money, and then more money, in order to buy the conveniences and luxuries of modern life, has brought great changes to the lives of most Frenchmen. More people are working harder than ever before in France. In the cities the traditional leisurely midday meal is disappearing. Offices, shops, and factories are discovering the great efficiency of a short lunch hour in company lunch rooms. In almost all lines of work emphasis now falls on ever increasing output. Thus the "typical" Frenchman produces more, earns more, and buys more consumer goods than his counterpart of only a generation ago. He gains in creature comfort and ease of life. What he loses to some extent is his sense of personal uniqueness, or individuality.

Some say that France has been Americanized. This is because the United States is a world symbol of the technological society and its consumer products. The so-called Americanization of France has its critics(批评家). They fear that “assembly line(装配线)life” will lead to the disappearance of the pleasures of the more graceful and leisurely (but less productive) old French style. What will happen, they ask, to taste, elegance(优雅), and the cultivation of the good things in life to joy in the smell of a freshly picked apple, a walk by the river, or just happy hours of conversation in a local café?

Since the late 1950s life in France has indeed taken on qualities of rush, tension, and the pursuit of material gain. Some of the strongest critics of the new way of life are the young, especially university students. They are concerned with the future, and they fear that France is threatened by the achievements of this competitive, goods-oriented culture. At times, they have reacted against the trend with considerable violence.

In spite of the critics, however, countless Frenchmen are committed to keeping France in the forefront of the modern economic world. They find that the present life brings more rewards, conveniences, and pleasures than that of the past. They believe that a modern, industrial France is preferable to the old.

1.Which of the following is not given as a feature(特色) of the old French way of life?

A. Leisure.           B. Taste.           C. Elegance           D. Efficiency.

2. The passage suggests that _________.

A. the smell of freshly picked apples is no more popular with the French

B. it’s now unlikely to see a Frenchman enjoying a walk by the river

C. in pursuing material gains the French are suffering losses elsewhere

D. student critics are great in number than the people enjoying the new lifestyle

3. Which of the following is NOT true about Frenchmen?

A. Many of them prefer the modern life style.

B. They actually enjoy working at the assembly line.

C. They are more concerned with money than before.

D. They are more competitive than the old generation.

4.Which of the following best states the main idea of the passage?

A. Great changes have occurred in the French way of Life.

B. The new life style in France is facing serious criticism.

C. France has been pushed in the forefront of the world economy.

D. Frenchmen used to be lazy and only enjoy life conveniences.
