(改为同义句) Some people don't know how they can have fun.

　　Some people don't know ______ ______ have fun.

　　All of us eat every day, but most of us don't understand nutrition. We often make mistakes in talking about good diet.

　　For example, many people think that foods, such as rice, bread and potatoes, will make one grow fat. In fact, those foods are very good to one's health. They are good sources of many vitamins. And in comparison with steak（肉排）and beef, they contain less amount of calories.

　　Some people don't like canned or frozen vegetables, because they think fresh vegetables cooked at home are always better. This is again wrong. In fact, whether the vegetables are good or not depends more on how they are prepared. Overcooking, for example, destroys many good qualities. Vegetables cooked in too much water can lose a large amount of vitamins.

　　It is widely believed that extra vitamins provide more energy. But taking more than the body needs doesn't make it function, better.

　　It is also wrong to say that vegetables grown in poor, worn-out soil are lower in vitamins than vegetables grown in rich soil. The vitamins in our foods are in the plants themselves. However the minerals in a plant depend on the minerals in the soil.

　　In short, there are many false ideas about nutrition. We need to correct them.

　　In 1956, a sailor from Sweden was on a ship. He wrote a letter, asking any young woman to write to him. He put the letter in a bottle and threw the bottle into the sea.

　　Two years later, a man found the bottle on a beach in Italy. He read the letter and showed it to his daughter. She was 18. As a joke, she wrote to the sailor. They began to exchange letters. In a few months, they were married.

　　Here is the second story. Back in 1924, a boy from Arkansas wrote his name on the back of his picture. He put the picture in a bottle and dropped the bottle into a river.

　　The bottle was not found for many years. Then one day a man named Bill picked it up on a beach in Florida. He pulled the picture out of the bottle and looked at it.
