【简答题】
Most English people have three names: a 1 name, a middle name and the family name. Their 2 name comes last. For example, my full name is Jim Allen Brown. Brown is my family name. My parents give me 3 names. People sometimes don't use their 4 name very much. So Jim Allen Brown is usually called Jim Brown. People 5 use Mr., Miss, Mrs. before their first name. So you can say Jim Brown, or Mr. Brown, 6 you should never say Mr. Jim. Sometimes people ask me about my name. “ When 7 you born, why did your 8 call you Jim ?” they ask, “ Why did they choose that name ?” The answer is they didn't call Jim. They called me James. James was the name of my grandfather. In England, people usually call me Jim for 9 . That's because it is shorter and 10 than James.
