Before the mid nineteenth century, people in the United States ate most foods only in season. Drying, smoking, and salting could preserve meat for a short time, but the availability of fresh meat, like that of fresh milk, was very limited, there was no way to prevent spoilage. But in 1810 a French inventor named Nicolas Appert developed the cooking and sealing process of canning. And in the i850s an American named Gall Borden developed a means of condensing and preserving milk. Canned goods and condensed milk became more common during the 1860s, but supplies remained low because cans had to be made by hand. By ]880, however, inventors had fashioned stamping and soldering machines that mass produced cans from tinplate. Suddenly all kinds of food could be preserved and bought at all times of the year.
Other trends, and inventions had also helped make it possible for Americans to vary their daily diets. Growing urban populations created demand that encouraged fruit and vegetable farmers to raise more produce. Railroad refrigerator ears enabled growers and meat packers to ship perishables great distances and to preserve them for longer periods. Thus, by the 1890s, northern city dwellers could enjoy southern and western strawberries, grapes, and tomatoes, previously available for a month at most, for up to six months of the year. In addition, increased use of iceboxes enabled families to store perishables. An easy means of producing ice commercially had been invented in the 1870s, and by 1900 the nation had more than two; thousand commercial ice plants, most of which made home deliveries. The icebox became a fixture in most homes and remained so until the mechanized refrigerator replaced it in the 1920s and 1930s.
Almost everyone now had a more diversified diet. Some people continued to eat mainly foods that were heavy in starches or carbohydrates, and not everyone could afford meat. Nevertheless, many families could take advantage of previously unavailable fruits, vegetables, and dairy products to achieve more varied fare.

听力原文： Television or TV is a modem wonder of electronics. It brings the world into our own home in sight and sound. Experiments leading to modem television took place more than a hundred years ago. By the 1920s, inventors and researcher had turned the early theories into working models. Yet it took another thirty years for TV to become an industry.
As an industry, TV provides jobs for hundreds of thousands who make TV sets and broadcasting equipment. It also provides work for actors, technicians, and others who put on programs. As an art, television brings the theatre and other cultural events into the home. Its influence on the life of average people is incalculable: it can influence their thoughts, their likes and dislikes, their speech, and even their dress. It can also add to their store of knowledge. Through advertising, television helps businesses and manufacturers sell their products to millions of persons. Television has brought political campaigns closer to the voters than in former days. Educational TV stations offer teaching in various subjects ranging from home nursing to art appreciation. Many large schools and universities have closed-circuit television equipment that will telecast lectures and demonstrations to hundreds of students in different classrooms, and the lecture can be put on video tape to be kept for later use. Some hospitals use TV to allow medical students to get close-up views of operations.
The programs that people watch are not only local and national ones. Since the launching of the first communication satellite, more and more programs are televised "live" from all over the world. Television viewers in San Francisco were able to watch the Olympic Games in Tokyo by means of a communication satellite named Syncom. And live telecasts now come from outer space: In 1969, the first astronauts landing on the moon televised their historic "moon walk" to viewers on the earth. Since then, astronauts have regularly sent telecasts to the earth.
It looks as if the uses of television in education, entertainment and communication appear to be endless. TV is certainly one of the major modem wonders of electronics in our changing world.

M: That's true. But we are especially impressed with how your influence contributes to good office relations and improved staff attitude toward the work.
W: Well, thank you. We do have a lot of good people in the office, and the new machinery is wonderful.

W: That's very true.
M: To make a long story short, the board wishes to reward your efforts by making you office manager next Monday. That means a $250 raise next month.
