写作题

阅读下面的短文, 然后按照要求写一篇150词左右的英语短文.

                                                        No One Dares to Help

     On a recent Sunday, I was buying groceries in a supermarket when I heard the sound of a car

accident. It was close but not very close, so I continued shopping.

     As I took a right turn on Munadhama Street, I saw a man lying on the ground in a small pool of

blood. He wasn't dead.

     The idea of stopping to help or to take him to a hospital crossed my mind, but I didn't dare. Cars

passed without stopping. Pedestrians and shop owners kept doing what they were doing, pretending

nothing had happened.

     I was still looking at the wounded man and blaming myself for not stopping to help. Other shoppers

peered at him from a distance, sorrowful and sympathetic, but did nothing.

     I went on to another grocery store, staying for about five minutes while shopping for tomatoes,

onions and  other vegetables. During that time, the man managed to sit up and wave to passing cars.

     No one stopped. No one did anything. No one lifted a finger.

The wounded died alone the street. The only reaction came from a woman in the grocery store. In a low

voice, she said, "My God, bless his soul."

     An offer of aid could have saved the man's life.
