  听力原文： The key question for any only child is this: Why were you an only child？ It's a key question for at least two reasons. If your parents had wanted several children, but could have you only, they are most likely to pour into you all the energy and attention that had been intended for several children. I call this the "Special Jewel" phenomenon. Only children, or special jewels often arrive when their parents are older-- usually in their thirties. These special jewels can become very spoiled and serf - centered. On the other hand, you may be an only child be cause your parents planned for only one and stuck to their plan. Your parents may give you a very strict and well-structured education to make you a little adult. Many only children grow up feeling unhappy because they always had to be such little adults. (33) A．Those who are themselves spoiled and self-centered. B．Those who expected to have several children but could only have one. C．Those who like to give expensive jewels to their children. D．Those who give birth to their only children when they are below 30.
