单选题{{B}}Passage 21{{/B}} Most people have had a dog or wanted one as their companion at some time in their lives. If you are thinking of buying a dog, however, you should first decide what sort of companion you need and whether the dog is likely to be happy in the surroundings you can provide. Specialists' advice is useful to help you choose the most suitable kind of dog. But in part the decision depends on common sense. Different dogs were originally developed to perform specific tasks. So, if you want a dog to protect you or your house, for example, you should choose the one that has the right size and characteristics. (21) {{U}}You must also be ready to devote a great deal of time to training the dog when it is young and give it the exercise it needs throughout its life, unless you live in the countryside and can let it run freely.{{/U}} Dogs are demanding pets. Cats love the house and so are satisfactory with their place where there is secure, but a dog is loyal to its master and consequently wants him to show proof of his {{U}}affection{{/U}}. The best time to buy a baby dog is when it is between 6 and 8 weeks old so that it can transfer its love for its mother to its master. If baby dogs have not established a relationship with the human being until they are over three months old, their strong relationship will always be with dogs. They are likely to be too shy when they are brought out into the world to become good pets.

单选题My father was a foreman of a sugar-cane plantation in Rio Piedras, Puerto Rico. My first job was to drive the oxen that plowed the cane fields. I would walk behind an ox, guiding him with a broomstick. For $1 a day, I worked eight hours straight, with no food breaks. It was very tedious work, but it prepared me for life and taught me many lasting lessons. Because the plantation owners were always watching us, I had to be on time every day and work as hard as I could. I"ve never been late for any job since. I also learned about being respectful and loyal to the people you work for. More important, I earned my pay. I was only six years old, but I was doing a man"s job. Our family needed every dollar we could make because my father never earned more than $18 a week. Our home was a three-room wood shack with dirty floor and no toilet. Nothing made me prouder than bringing home money to help my mother, father, two brothers and three sisters. This gave me self-esteem, one of the most important things a person can have. When I was seven, I got work at a golf course near our house. My job was to stand down the fairway and spot the balls as they landed so the golfers could find them. Losing a ball meant you were fired, so I never miss one. Some nights I would lie in bed and dream of making thousands of dollars playing golf and being able to buy a bicycle. The more I dreamed, the more I thought. Why not? I made my first golf club out of guava limb and a piece of pipe. Then I hammered an empty tin can into the shape of a ball. And finally I dug two small holes in the ground and hit the ball back and forth. I practiced with the same devotion and intensity I learned working in the field—except now I was driving golf balls with club, not oxen with a broomstick.
