Passage 1

Questions 1 to 5 are based on the following passage.

     The passengers on the bus watched sympathetically as the young woman with the white cane made her way cautiously up the steps. She paid the driver and then, using her hands to feel the location of the seats, settled into one. She placed her briefcase on her lap and rested her cane against her leg.

    It had been a year since Susan, thirty-four, became blind. As the result of a medical accident she was sightless, suddenly thrown into a world of darkness, anger, frustration and self-pity. All she could cling to was her husband Mark.

    Mark was an Air Force officer and he loved Susan with all his heart. When she first lost her sight, he watched her sink into despair and he became determined to use every means to help his wife.

    Finally, Susan felt ready to return to her job, but how would she get there? She used to take the bus, but she was now too frightened to get around the city by herself. Mark volunteered to ride the bus with Susan each morning and evening until she got the hang of (摸清情况) it. And that was exactly what happened.

For two weeks, Mark, military uniform and all, accompanied Susan to and from work each day. He taught her how to rely on her other senses, specifically her hearing, to determine where she was and how to adapt to her new environment. He helped her befriend the bus drivers who could watch out for her, and save her a seat.

    Each morning they made the journey together, and Mark would take a taxi back to his office. Although the routine of going back and forth was costly, Mark knew it was only a matter of time before Susan would be able to ride the bus on her own.

    Finally, Susan decided that she was ready to try the trip on her own. Monday morning arrived. Before she left, she embraced her husband tightly. Her eyes filled with tears of gratitude for his loyalty, his patience, and his love. She said good-bye and, for the first time, they went their separate ways. Monday, Tuesday, Wednesday, Thursday... Each day on her own went perfectly, and a wild gaiety (快乐) took hold of Susan. She was doing it! She was going to work all by herself!.

When Susan got on the bus, the passengers ______.
