题目内容
Most people think of racing when they see greyhounds(灰狗)and believe they need lots of exercise. They can actually be quite lazy! Greyhounds are good at fast races but not long-distance running. They do need regular exercise but they like to run for a short burst and then get back on the bed or a comfortable seat. Another misunderstanding is that greyhounds must be aggressive(好斗的)because they are big in size. In fact greyhounds love people and are gentle with children.
Greyhounds can live for 12 14 years but usually only race for two or three years, and after that they make great pets. They don’t need a lot of space, don’t make a lot of noise, and don’t eat a lot for their size.
Normally, greyhounds can be as tall as 90 cm. There is, however, a small-sized greyhound, which stands only 33 cm. Greyhounds come in a variety of colors. Grey and yellowish-brown are the most common. Others include black, white, blue, red and brown or a mix of these.
Greyhounds have smooth body coats, low body fat and are very healthy. Because they’re slim(苗条的)they don’t have the leg problems like other dogs the same height . But they do feel the cold, especially since they would much rather be at home in bed than walking around outside.

Farming was once the chief way of life in nearly every country. People cannot live without food, and nearly all their food comes from crops and animals raised on farms. Not many people farm for a living any more, but farming remains the most important work in the world.
Before the nineteenth century, the typical American family lived on a small farm. They raised pigs, cattle, sheep, chickens, and planted corn, fruits, garden vegetables, and wheat. Everyone worked long and hard, but the results were often poor. Families barely harvested enough food for themselves. This situation began to change during the last half of the 1800's and it changed remarkably(明显地) in the next century.
Scientific methods and labor-saving machinery have made farming increasingly productive. The development of improved plant varieties and fertilizers has helped double and even triple the production of some major crops. More scientific animal care and animal raising have helped increase the amount of meat and products that animals produce. At the same time, the use of tractors and other modern farm equipment has sharply reduced the need for farm labor.
As farming has become less important as a way of life in the United States, it has become more important as a source which offers materials to industry. Today's successful farmers are experts not just in agriculture but also in accounting, marketing, and finance. Farms that are not run in a similar way have great difficulty surviving.
