Supply a topic sentence for each paragraph.Beaches ______________________________. Thailand has miles of empty beaches. The beaches there are beautiful, clean, and uncrowded, even in summer. People can spend the whole afternoon on a beach and not see many people there. However, in Japan, the beaches are very crowded. When you visit some popular Japanese beaches you can hardly find a place to sit down. The beaches in Northern Europe are different in another way. Most people go to the beach only to sunbathe because the water is cold. The beaches are rocky along the French Riviera, not sandy as they are on tropical islands. Each type of beaches — empty or crowded, sandy or rocky — has its own special characteristics to enjoy.
