Outside, I heard the sounds of cats crying. I couldn’t stop- I would have to look for the cats after the fire was put out.It took a long time to finally bring the big fire under control. No one inside was hurt. At that point I was free to find out where the cat noises were from. There was still a lot of smoke and heat coming from the building. I followed the meowing to the sidewalk in front of the garage. There, crying and huddled together, were five frightened kittens . They must have been inside the building, as their fur was badly hurt.I wanted to find the mother cat. It was obviously that she had gone into the burning garage and carried out all her babies, one by one----unbelievable.We finally found her. Her paws and face were blackened, and her fur was burned all over. You could even see her reddened skin under the burned fur. She could hardly move. I picked her up, and she relaxed in my arms as much as her pain would allow. I was determined to save this brave little cat and her family.The veterinarian told me they would watch the kittens and their mother for the night, but they weren’t confident about the about the mother’s chances.About a week later, I found out she was going to live. We named her Scarlet because of her reddened skin.I was happy to see Scarlet get together with the kittens again. She touched each of them, nose to nose. She had risked her life five times-and it had paid off. All of her babies had survived.As a firefighter, I see heroic acts every day. But what Scarlet showed me that day was the kind of bravery that can only come from a mother’s love.小题1:Which f the following is TRUE according to the story?A．The writer went to look for the cats as soon as he heard them cryingB．The firefighters put out the fire quickly and no one was hurt.C．The writer didn’t find the cats until the smoke and heat were gone.D．The mother cat moved all her babes out of the fire to a safe place.小题2:Why was the writer determined to save the cats?A．Because he was amazed at the mother cat’s courage.
