However, few of the ―tigers‖ we face in our lives cause a serious physical threat to our existence. They cause us no end of stress, triggering(引發(fā) ) the full activation of our fight or flight response. They tend to cause us to overreact to the situation in a counterproductive (事與愿違的 ) way. It is counterproductive to hit someone (the fight response) or run away (the flight response). By recognizing the symptoms, we can begin to take steps to handle the stress overload. By learning to recognize the signals of fight or flight activation, we can avoid reacting excessively (過度地 ) to events and fears that are not life threatening. In doing so, we use this extra energy to help ourselves, borrowing the beneficial effects in order to change our emotional environment and deal productively with our fears, thoughts and potential dangers. 28.

B Recently I accepted a challenge to join Naasih, a motivational speaker, on a voyage through India designed to refresh my spirit. After too many hours, Naasih and I arrived in the slum(貧民窟 ) just as the sun was breaking across the smoggy Delhi sky. It seemed as if the small houses extended for miles, an ocean of tin roofs and laundry lines. Finally, Naasih stopped and turned to me. ―Give me your bag,‖ he said. I handed it to him. I had promised to follow his directions, and in return, I was hoping to find whatever I thought was missing from my life. ―I will meet you back here at sunset,‖ Naasih said and walked away. I began to walk through the streets. No one paid too much attention to the tall, hairless man walking among them. My throat was dry, my stomach turning over with hunger. And then I saw a small house and I knocked softly on the door. A young, skinny man, no older than 25, came to answer it. As I soon found out, the man is named Sankar and he was a Lakers fan.
