     One afternoon, Kate and her brother, Bob, went out to play. Kate was eight, and Bob was ten. "Let's

go to the bridge and we can see fish in the river." said Kate.

     "I don't know…" Bob said. "Mum told us, 'Don't go on the bridge.' She said it's dangerous."

     Kate said, "I am not afraid. Are you?"

     They walked onto the bridge and began looking for fish in the river. The bridge was a train bridge.

Trains went over the bridge three times a day.

coming!" Bob shouted. "Run!" He ran to the end of the bridge. He was safe.

the  train  tracks (铁轨). There was no time to leave. She had to lie down  between  the  tracks. A few

seconds later, the train went over the girl, but  she  was not  hurt  at all. She  stood up  and said to  Bob,
