　　25 In its country of Germany, the hot dog was called the frankfurter. It was named after Frankfurt, a German city. Frankfurters were first sold in the United States in the 1860s. Americans called frankfurters “dachshund sausages”. A dachshund is a dog from Germany with a very long body and short legs. Dachshund sausages first became popular in New York, especially at baseball games. At games they were sold by men who kept them warm in hot-water tanks. As the men walked up and down the rows of people, they yelled, “Get your dachshund sausages! Get your hot dachshund sausages!” People got the sausages on buns, a special bread.

　　One day in 1906, a newspaper cartoonist named Tad Dargan went to a baseball game. When he saw the man with the dachshund sausages, he got an idea for a cartoon. The next say at the newspaper office he drew a bun with a dachshund inside ---not a dachshund sausage, but a dachshund. Dorgan didn’t know to spell dachshund. Under the cartoon, he wrote “Get you hot dogs!”

　　The cartoon caused deep interest and excitement, and so was the new name. If you go to a baseball games today, you can still see sellers walking around with hot-water tanks. As they walked up and down the rows they yell, “Get your hot dogs here! Get your hot dogs!”

　　The main purpose of the passage is to show_____.

　　A the home country of the hot dog

　　B the origin of the hot dog

　　C the selling of the hot dog

　　D the cartoon of the hot dog

　　26 All of us eat every day, but most of us don’t understand nutrition. How much do you know about good nutrition? Are the following statements true or false?

　　1. People who don’t eat meat can stay healthy.

　　True. As long as people eat enough milk, eggs and meat alternated, they can get enough protein.

　　2. Fresh vegetables cooked at home are always more nutritious than canned vegetables.

　　False. The difference depends on how vegetables are prepared than whether they are fresh or canned. Vegetables cooked in too much water lose a great amount of vitamins.

　　3 Food eaten between meals can be just as good for health as food eaten at regular meals.

　　True. Nutritional value depends on what type of food you eat, not when you eat them. Eating an egg or an orange between meals can contribute to a good diet.

　　4. Taking extra vitamins beyond the recommended daily allowances won’t give you more energy.

　　True. It’s widely believed that extra vitamins provide more energy. But taking more than the body needs doesn’t make it function better, not more than overfilling your gas tank makes your car run better.
