Sandy had recently moved into the neighborhood with her four kids: Jane, Joe, Christopher, and her youngest, eighteen-month-old Kim. She seemed happy to have kids nearby, until she saw our dog, Sam. Sam, our shiny black dog, loved to play with the kids and protect them. But Sandy had a fear of dogs, and she started to back away as Sam approached. I grabbed Sam's collar and made him sit, trying to ease Sandy's discomfort. Sandy mentioned that she needed to get her kids ready to go to their grandmother's house. Just then, her door opened and her kids rushed out. Sandy shouted at them to stay away from Sam. The kids huddled(蜷缩) around their mom, looking at Sam cautiously(谨慎地). Emma,my daughter. showed the kids how to approach a dog slowly and properly. The kids were won over by Sam's friendly nature, but I knew it would take some time for Sandy to change her viewpoint. After that incident, we made sure that Sam didn't go near our neighbors without me present. One day, when the kids were playing across the street. I noticed the eighteen-month-old baby heading towards a small hill. I saw a car approaching and shouted to everyone to watch the baby. Without hesitation, Sam rushed out the door and ran across the street towards the baby. He ran to the boy in time to gently push the baby away from the oncoming car. The kids cheered, completely unaware of the danger. They thought Sam had come to play. Within a year, Sam had made friends with all the neighbors. Even Sandy started to warm up to Sam and would occasionally come over to give him a hug. 1. How did Sandy feel when she first saw Sam? A. Excited. B. Amazed. C. Fearful. D. Awkward. 2. What did Sandy's kids do at the sight of Sam? A. They looked at Sam with watchful eyes. B. They formed a circle to protect their mom. C. They held him by the collar to make him sit. D. They prepared to escape from the dog. 3. How did Sam save Kim from danger? A. By running in front of the car to block it. B. By pushing the baby away from the car. C. By rushing to Sandy's house to get help. D. By jumping to the front of the coming car. 4. Which of the following can best describe Sam? A. Dangerous. B. Funny. C. Brave. D. Sensitive. B When you go on vacation next time, make sure to take lots of pictures of the wildlife you sec. These photos can help save different types of wildlife because of a new field called “imageomics ” . Imageomics uses computers to study pictures of wildlife and learn information from them. Until recently, scientists didn't have the technology to analyze(分析) the data in wildlife photos. But now, machine learning and computer vision are helping researchers unlock valuable information hidden in these images. There are platforms where people can share their wildlife photos, like e-Bird, iNaturalist and Wildbook. These platforms help scientists keep track of different species and create databases. If you have rare(稀有的) photos of wildlife, it's a good idea to share them on these platforms. Scientists have limited time and resources to study all endangered wildlife in the world. By using artificial intelligence(人工智能) to analyze public photos, we can learn more about different species and their behaviors. This technology can even help us find things in photos that humans might miss. It's important to use the collected information responsibly and protect it from poachers(偷猎者). If we do that, imageomics can not only help save wildlife but also contribute to other fields like medicine and agriculture. 5. How can imageomics help scientists study wildlife? A. By offering information from wildlife. B. By analyzing the data in wildlife photos. C. By analyzing the trend of human population. D. By knowing the origin of biological processes. 6. What are the platforms where people can share their wildlife photos? A. EBird, iNaturalist and Wildbook. B. Imageomics, eBird and Wildbook. C. Imageomics, e-Bird and iNaturalist. D. Photos of wildlife, iNaturalist and Wildbook. 7. Why should people share their rare wildlife photos on platforms? A. To appreciate the beauty of wildlife. B. To contribute to the public safety. C. To inspire others to protect nature. D. To help scientists study wildlife. 8. Which can be the best title for the text? A. Computers help identify the biological features B. Poachers stop killing threatened animals C. Photos can save wild species D. Photos can protect our environment 四、完形填空(共15小题：每题2分, . 满分30分) 阅读下面短文, 从短文后各题所给的 A、B、C 和 D 四个选项中, 选出可以填入空白 处的最佳选项。 On a cold winter, I relaxed myself on the sofa after dinner.
