第一节（共15小题；每小题2分，满分30分）

It was getting dark when Lisa was returning from teaching out in a small community. She’d been traveling the same route for over a year and there was seldom traffic on this highway.

Lisa remembered back to her previous experiences. In those days she was constantly picking up strangers on the road. Her family became greatly concerned about her safety, but she continued the practice until the day her sister told her that one of her friends had been shot by a hitchhiker (搭便车者). That was when the family heard the promise, “No more hitchhikers, I promise!”

When she thought back to these things, she suddenly noticed that a car was parked on the road ahead. Then she saw a man waving. He was in trouble, she thought. But suddenly she remembered the promise. She knew this road well and the chances of another car coming along to help were very little. Now as the man ran toward her car she shook with fear, and didn’t know if he was truly in need. She could not leave him here in this storm. The stranger explained that his car was broken. She knew she had to break the promise. She told him to get in. They drove for an hour into the next city and she took him to a telephone box. She waited until he had made a call. When he reported back to her that a family member would soon be there for him, she wished him well and left.

Tears fell on her cheeks as she drove away. It felt as though she had been holding her breath for an hour. “I hope they’ll understand why I had to break my promise.”
