In the city I live in, some seats on every bus come in orange color, different from the rest which are blue. Those seats are intended for (预留) a certain group of people—the old and some who need special care, such as the disabled or those with small babies. So you can often see young people choose to take others seats i1. of the orange ones if possible.

One day, my friend Lisa got on a bus and found the only untaken seat was an orange one. She hesitated(犹豫) for a moment and slowly walked to it and s2. down. As the bus went on, passengers(乘客) gather from stop to stop and the bus became really crowded(拥挤) . At that time, someone near the door asked loudly if there was anybody who would like to o3. a seat to the old man who had just got on the bus. On hearing it, Lisa looked a4. to see where the old man was. She was even about to get up but found it d5. for her to stand up. Thinking that someone near the old man would help him, she remained(保持) seated. In fact, she had another r6. for sitting but she said nothing. To her s7. , she soon became the target of criticism(批评的目标) from some people standing beside her.

“Shameless,” a voice said.

“Morality decays(道德败坏),” another voice added.

Lisa kept s8. as the short conversation went. She didn’t want to say anything. She “should” feel ashamed(羞愧). Lisa turned her face to the window to hide her embarrassment(尴尬).

If you were a passenger on that bus, would you stand out against her and blame(责怪) her for not giving up her seat? If I hadn’t known the story of Lisa’s side, I would. However, the truth is: Lisa had just a small o9. in hospital last week and was in recovery (恢复). Her doctor had told her to sit instead of s10. as much as possible. The long bus trip would give her trouble if she stood all the way.
