阅读理解。 My wife Julie and I were out on the road that runs around where we live. Two dog walkers passed by and we heard one of them say, 'Never seen that dog around here before.' We looked down the hill and saw an old black dog stumbling(蹒跚) painfully up the hill. We bent down, talked gently to the dog and patted it. I checked and there was a collar. There was a phone number on the collar, but no one answered. The dog was painfully thin. It didn't have many teeth left and, well, it just seemed done. Julie ran home to get some of our dog's food while I tried to encourage the dog to come along with me. Julie got home and back again when I was only half way there. So, we sat down on the sidewalk while our new friend made short work of the food. Eventually we got her home. We gave her a blanket, more food, kept her warm and wondered what to do next. After trying for many times we got a response from the number. A lady came around with a bunch of flowers for us. She explained that Tara had been her father's dog. She was very old and should probably be put to sleep, but the lady just couldn't bring herself to do it. So, Tara was safely returned home. Here is the truth of the story: Actually Julie and I were out that morning because I was leaving. She was trying to persuade me to come back, but I wasn't hearing anything that made that sound likely. I was about to turn and go when an old, worn out dog walked between us and collapsed. Suddenly we had something more important than our problem to worry about. There was a creature in need right before us and we had to work together to help it. We did help it. And here am I writing the story in my own home, in my own family. In the song 'Love Is Not a Fight' Warren Barfield talks about marriage. At one point he sings, 'And if we try to leave, may God send angels to guard the door.' Sometimes angels come disguised (伪装) as dogs. 1. Which of the following statements is true? A.
