18．　　Hello, everyone! Welcome to the world famous Night Safari in Singapore (新加坡). It's the first of its kind. Before you start your unbelievable journey (旅程) this evening, I would like to introduce you to our unusual zoo.
　　It opened on May 26, 1994 at a cost of 63 million Singapore dollars. Today, this "theme zoo" is home to more than a thousand animals from 120 species (物种) that are active at night. We have Indian rhinos, Malaysian tigers, Nile hippos, Asian elephants and much more! About 1.1 million people visit us every year.
　　Night Safari's location in the tropical forest (热带雨林) of Singapore is perfect, because it's similar to the animals' natural environment (自然环境) in Africa and Asia. To give the animals as much freedom as possible, moats (沟) and glass walls, not cages (笼子), keep them apart. The moats look very natural, like small rivers! Do not fear — animals are safe from each other, and you are safe from the animals!
　　There are a couple of things we ask of all visitors. First, bright light (亮光) may scare the animals, so please turn your camera flash off. Secondly, these animals don't like loud noises. Please help us keep the experience quiet and speak in a low voice.
　　Are you ready? Whether you ride on our tram (电车) or simply walk on the path (小路), we know you will love the Night Safari.

19．　　Tiffany, a 16-year-old girl, is very shy. In September, her best friend, Sophie, moves abroad with her family because she has to study in America. She even says she will not come back for a few years. Tiffany becomes lonely and helpless. "I am really sad when I hear the bad news and I don't know what to do," Tiffany recalls (回忆). "I stays in my room for a whole week. Then my aunt takes me to a sports club one Saturday and I see so many young people playing sports there. I sign up (报名) for the beginner's classes in volleyball and from that day on I often play this sport. Now I practice twice a week there. It is wonderful playing sports in this club and I make lots of friends as well. What's more, I feel I am much healthier than before."
　　For most people, that is one of the attractions (吸引人之处) of joining a sports club. You can get to know other young people who have the same interests. You don't have to sit down and talk to strangers (陌生人). You go in for sports and it is easier to understand your partners on the same team. Now Tiffany gets on very well with her friends, and now she is not a shy girl any more. She also gets more confidence.
　　Try to do regular (规律的) sports. The mind needs exercise as well as the body.
