题型:单项选择题 A1/A2型题

One summer vacation in my college, my roommate Ted asked to me to work on his father’s farm in Argentina. The idea was exciting. Then I had second thoughts. I had never been far from New England, and I had been homesick my first few weeks at college. What about the language? The more I thought about it, the more the idea worried me.

Finally, I turned down the invitation. Then I realized I had turned down something I wanted to do because I was scared and felt depressed(沮丧). That experience taught me a valuable lesson and I developed a rule for myself: do what makes you anxious(焦虑); don’t do what makes you depressed.

In my senior year, I wanted to be a writer. But my professor wanted me to teach. I hesitated. The idea of writing was much scarier than spending a summer in Argentina. Back and forth I went, making my decision, unmaking it. Suddenly I realized that every time I gave up the idea of writing, that downhearted feeling went through me.

Giving up writing really depressed me. Then I learned another lesson. To avoid the depression meant having to bear much worry and concern.

When I first began writing articles, I often interviewed big names. Before each interview I would get butterflies in the stomach. One of them was the great composer Duke Ellington. On the stage and on television, he seemed very confident. Then I learned Ellington still got stage fright(害怕). If Ellington still had anxiety attacks, how could I avoid them? I went on doing those frightening interviews. Little by little, I was even looking forward to the interviews. Where were those butterflies?

In truth, they were still there, but fewer of them. I had learned from a process psychologists(心理学家) call “extinction”. If you put an individual in an anxious situation often, finally there isn’t anything to be worried about, which brings me to a conclusion: you’ll never get rid of anxiety by avoiding the things that caused it.

The point is that the new, the different, is definitely scary. But each time you try something, you learn, and as the learning piles up, the world opens to you.
