　　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 yellowishbrown 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.

答案：B;D;D;B
解析：

(1)通读全文可知，本文主要描述了灰狗的性格、生命年限、习性及身高、体重等特点，大体上向我们介绍了greyhounds，并提出了人们对greyhounds的错误观点，故答案应选B项。

(2)由第二段的第二句可知，“They don't need a lot of space,...”，故A项不对；由第一段的第四句可知，“They do need regular exercise...”，故B项不对；而由文中可知greyhounds不擅长长距离跑步，喜欢卧床，故不可能成为好的guard dogs，而可以成为great pets。故D项正确。
