Here is a man who believed in his own ability even as a boy, and that confidence helped shape his adult life. At the turn of the last century, a young boy quit school to help with the family expenses. When he was fifteen, he became interested in automobiles and worked in a garage. He subscribed to a correspondence home study course on automobiles and, after a long day in the garage, studied at the kitchen table by lamplight. When he felt ready, he walked into the Frayer-Miller Automobile Company of Columbus, Ohio. When Mr. Frayer noticed him, he asked, "Well, what do you want?" "I just thought I'd tell you I'm coming to work here tomorrow morning," the boy replied. "Oh! Who hired you?" "Nobody yet, but I'll be on the job in the morning. If I'm not worth anything, you can fire me." Early the next morning the young man returned to the plant. Noticing the floor was thick with metal shavings and accumulated dirt, the boy got a broom and set out to clean the place. Because of his self-confidence and work ethic, the boy's future was predictable. He went on to stand out in many fields, including automobile racing, piloting World War I planes and founding what was to become one of America's largest airline companies -- Eastern Airlines. People who become more confident habitually encourage themselves. Without confidence, we are not likely to move far in the direction of our dreams. But become our own best friend and almost anything will be possible. It is important that we always believe in ourselves. In order to reach victory, we must believe in ourselves even when we make mistakes and fall short. Question: We can learn from the boy's words that _ . Options: A: he believed in himself B: he looked down upon others C: he was very generous D: he wanted to show off his competence

Millions of them, all black. Cars were rare. Yet since my arrival in Beijing last year, I've found the opposite is true. There are millions of cars. However, people still use their bicycles to get around. For many, it's the easiest and cheapest way to travel today. Bicycles also come in different colors---silver, green, red, blue, yellow, whatever you want. It's fun watching people biking. They rush quickly through crossroads, move skillfully through traffic, and ride even on sidewalks . Bicycles allow people the freedom to move about that cars just can't provide. Eager to be part of this aspect of Chinese culture, I decided to buy a bicycle. Great weather accompanied my great buy. I immediately jumped up on my bicycle seat and started home. My first ride home was orderly . To be safe, I stayed with a "pack" of bikers while cars on the streets came running swiftly out of nowhere at times. I didn't want to get hit. So I took the ride carefully. Crossing the streets was the biggest problem. It was a lot like crossing a major highway back in the United States. The streets here were wide, so crossing took time, skill and a little bit of luck. I finally made it home. The feeling on the bicycle was amazing. The air hitting my face and going through my hair was wonderful. I was sitting on top of the world as I passed by places and people. Biking made me feel alive. Question: According to the author, why are bicycles still popular in China today? Options: A: Because they are convenient and inexpensive. B: Because they are traditional and safe. C: Because they are colorful and available. D: Because they are fast and environment friendly.

Throughout history people have sought answers to these questions and others. Various myths offer the hope of great longevity. In the imaginary land of Shangri-La, for example, people are said to lead a charmed existence for a thousand years. The Spanish explorer Ponce de Leon was convinced that he would find the Foundation of Youth in what is now the state of Florida. According to the Bible, Methuselah lived to be more than 900 years old. The subject of longevity is fascinating, and scientists study individuals such as Jeanne Calment to learn about the aging process. Calment died in 1997 in Arles, France, at the age of 122. She never married, and she lived in her own apartment until moving to a retirement community when she was 109. Most scientists agree that bodies will last, at best, about 125 years. This potential has changed little since modern human beings appeared more than 100 thousand years age. Recent improvements in medicine and the environment have extended life expectancy, especially for those from poorer parts of the world. It is not clear, however, whether such improvements will lengthen life expectancy beyond a certain point. Life expectancy is the number of years an infant can be expected to live, given the conditions into which it is born. Life expectancy, therefore, is affected by nutrition, medical care, and social and political circumstances. An individual's genetic makeup is also an important factor. Children from long-lived families can hope to enjoy long lives themselves. According to recent data, the average life expectancy worldwide in 1998 was 67 years. This can be compared with an average life expectancy of 77 in the United States. In 1970 the average life expectancy worldwide was 61 years, or 6 years less than it was in 1998. This same period saw a drop in infant mortality --- the death of a child before the first birthday---from 80 births out of 1,000 to 54... Question: Infant mortality is defined as _ . Options: A: the number of children born alive B: the kinds of behavior typical of very young children C: the number of children, out of 1,000 births, who die before their first birthday D: the typical and obvious thoughts of very young children
