Question

     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 33cm. 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.

A. to tell people how to raise greyhounds            B. to let people know more about greyhounds

解析:

56.解析  略

57.解析：这是一道推断题。从第一段“They can actually be quite lazy”和“they do need regular excise”可以推断出灰狗比较懒惰，需要锻炼，选D。从“misunderstanding”和“greyhounds must be aggressive”可知灰狗并不好斗，A不对。文中说到灰狗怕冷，所以不会总是在外面，B不对。灰狗是great pets，而不是guard dogs，C也不对。

58.解析：这是一道细节题。根据第二段最后一句，“They don’t need a lot of space, don’t make a lot of noise, and don’t eat a lot for their size ”可知它们很安静，容易照顾。

59.解析：这是一道推断题。从最后一句，“But they do feel the clod… ”可知灰狗比较怕冷，需要注意保暖。
