Diving is popular all over the world. It is usually done in the ocean, but divers also explore other bodies of water, including lakes, rivers, and ponds. Snorkeling (戴呼吸管潜泳) on the surface (or just below) is a common form of diving, but many people use scuba (水肺), which stands for self-contained underwater breathing apparatus. Scuba divers carry a tank of air that allows them to breathe while diving underwater.
Throughout history, people have been fascinated by life underwater, and the Professional Association of Dive Instructors (PADI) estimates that there are now 6 million active divers worldwide. They engage in many different types of diving, of which wreck, cave, commercial, and military diving are just a few. The most common form of diving is sport diving, or recreational diving, which is practiced at depths of less than 130 ft (39 m). From these depths, divers can make a straight ascent to the surface. Diving beyond this limit requires advanced training. Because pop

Movies are the most popular form of entertainment (娱乐) for millions of Americans. They go to the movies to escape their normal everyday existence and to experience a life more exciting than their own. They may choose to see a particular film because they like the actors or because they have heard the film has a good story. But the main reason why people go to the movies is to escape. Sitting in a dark theater, watching the images on the screen, they enter another world that is real to them. They become involved in the lives of the characters in the movie, and for two hours, they forget all about their own problems. They are in a dream world where things often appear to be more romantic and beautiful than in real life.
The biggest "dream factories" are in Hollywood, the capital of the film industry. Each year, Hollywood studios make hundreds of movies that are shown all over the world. American movies are popular because they tell stories and they are well-made.
