     The snow lasted until last Friday. I opened the window this morning and saw the sun  but I felt much

colder.

     "You'd better go to work on foot , dear,"said my husband,"It is dangerous for you to drive."

     I thought him right and agreed. It would take me about forty minutes to go my hospital. There was

about an hour left, so I started, with a bag of sandwich for breakfast. In the streets there was thick snow

and ice and the traffic was less than before and people walked carefully. Suddenly I saw a car going fast.

The driver tried to pass the crossing before the lights turned red. Maybe he didn't see two boys in the

middle of the street. His car knocked down(撞倒)one boy and stopped just in front of the police box.

     People crowded around the boy at once. I rushed out of the gathering crowd (聚集的人群)and was

going to look him over. But a man pushed me aside and said,"Step back(向后退),please. I,ve had a

course in first aid(急救)."

     I had to stand and watch his ministrations(救助) for a few minutes. Then I said to him,"When you

need a doctor, sir, I,m already here."
