Is your family interested in buying a dog? A dog can be a pleasant companion（伙伴） to your family, but if you choose the wrong kind of dog，you will have a lot of troubles.
Families should sit down and thoroughly discuss the possible problems before buying a dog. Even if the children in your family are the ones who want the dog, the parents are the ones who are really responsible for seeing that the animal is properly cared for. If you don’t know much about dogs, it is a good idea to go to the library for books about different kinds of dogs, as well as books about how to train a young dog. In reading about the different breeds(种类)you should know that a dog described(描述)as very alert(机敏灵活的)may be too active. When a book describes a dog as an excellent hunting dog, it probably means that the dog won’t be happy living in a small house. Dog breeds vary(变化)in popularity as the years go by. One of the most popular dogs these days is the German shepherd（牧羊犬）. This is because it provides protection as well as companionship（陪伴）. The family should be warned that these dogs grow up to be very big, and may be too powerful for children to control. If space is limited, a toy dog may be a good choice. These dogs are very small and easy to train. They don’t need to be walked daily, since they can exercise in the home.

We often talk about ourselves as if we have permanent genetic defects(缺陷) that can never be changed. “I’m impatient.” “I’m always behind.” “I always put things !” You’ve surely heard them. Maybe you’ve used them to describe .
These comments may come from stories about us that have been for years—often from childhood. These stories may have no in fact. But they can set low expectations for us. As a child, my mother said to me, “Marshall, you have no mechanical （操作机械的） skills, and you will never have any mechanical skills for the rest of your life. ” How did these expectations my development? I was never to work on cars or be around . When I was 18, I took the US Army’s Mechanical Aptitude Test. My scores were in the bottom for the entire nation!
Six years later, , I was at California University, working on my doctor’s degree. One of my professors, Dr. Bob Tannbaum, asked me to write down things I did well and things I couldn’t do. For my strong points, I down, “research, writing, analysis, and speaking. ” For the , I wrote, “I have no mechanical skills. ”
Bob asked me how I knew I had no mechanical skills. I explained my life and told him about my performance on the Army test. Bob then asked, “ is it that you can solve mathematical problems, but you can’t solve easy mechanical problems?”
Suddenly I realized that I didn’t from some sort of genetic defect. I was just living out expectations that I had chosen to . At that point, it wasn’t just my family and friends who had been my belief that I was mechanically hopeless. And it wasn’t just the Army test, either. I was the one who kept telling myself, “You can’t do this!” I realized that as long as I kept saying that, it was going to remain true. , if we don’t treat ourselves as if we have genetic defects that we can never get over, we can do well in almost we choose.
