You probably know what fast food is. It is cooked food that is ready almost as soon as you enter a public eating place. It does not cost much.
Most fast food restaurants are chain (连锁) restaurants. That means each one is part of a huge company. Each restaurant in the chain has the same large, colorful sign that can be easy to recognize from far away. Each offers its own carefully limited choice of foods. Each kind of hamburger or piece of chicken tastes the same at every restaurant in the chain.
The fast food industry began with two brothers in the nineteen forties. Mac and Dick McDonald owned a small, but very successful restaurant. They sold only a few kinds of simple food, especially hamburgers. People stood outside the restaurant at a window. They told the workers inside what they wanted to eat. They received and paid for their food very quickly. The food came in containers that could be thrown away. The system was so successful that the McDonald brothers discovered they could sell a lot of food and lower their prices.
Ray Kroc sold restaurant supplies. He recognized the importance of the McDonald brothers' idea. Kroc paid the McDonald brothers for permission to open several restaurants similar to theirs. He opened the first McDonald's restaurant near Chicago in nineteen fifty-five. Soon, more McDonald's were opening all across the United States. Other people copied the idea and more fast food restaurants followed.
Fast food restaurants spread quickly in the United States because of franchising. Franchising means selling the legal right to operate a store in a company's chain to an independent business person. If the company approves, the business person may buy the store for a period of years. Each restaurant also gives the company about ten percent of the money it earns in sales. Today, over seventy percent of McDonald's restaurants worldwide are owned and operated by independent businessmen and women.

Although more and more people are exercising regularly，experts note that eating right is also a key to good health.Nutritionists recommend（推荐）the “food pyramid” for a simple guide to eating the proper foods.At the base of the food pyramid are grains and fiber.You should eat six to eleven servings of bread，cereal，rice，and paste every day.Next up the pyramid are vegetables and fruits; five to nine daily servings from this group are recommended.The next pyramid level is the dairy group.Two or three servings a day for milk，yogurt，or cheese help maintain good nutrition. Moving up the pyramid，the next level is the meat，fish，beans，eggs，and nuts group，of which everyone should eat only three servings a day.At the very top of the pyramid are fats，oils，and sweets; these foods should be eaten only infrequently.?

　　You don't have to shop in health food stores to follow the guidelines.One easy way to plan menus that follow the food pyramid is shop only in the outer aisles of the grocery store.In most supermarkets，fresh fruits and vegetables，dairy，fresh meat and frozen foods are in the outer aisles of the store.Grains，like paste，rice，bread，are located on the next aisles，the first inner rows.Finally，the farthest inside of the store is where you'll find chips and snacks，cookies and pastries，soda pop and drink mixes.These are the kinds of foods that nutritionists say everyone should eat rarely，if at all.If you stay in the outer aisles of the grocery store，you won't be tempted to buy foods you shouldn't eat，and you will find a wide variety of healthy foods to choose from.Another benefit of shopping this way is that grocery shopping takes less time.?

The Mystery of the Flashing Fireflies

During summer nights fireflies flash in the darkness. They look like bright spots of light dancing on the breeze. Catching them in a jar for a few minutes can be fun. Fireflies are not really flies, though. They are winged beetles. Scientists are using these special beetles to learn more about our world.

The reason a firefly flashed its light is to find a mate. There are around two thousand species, or kinds, of fireflies. Fireflies mate only with their own species. Each kind of firefly has its own flash pattern. It is important that fireflies recognize this pattern. That way they can find bugs of their own kind. The male firefly flies around in the sky while the female firefly stays close to the ground.

For many years, how a firefly flashes its light was a mystery. Scientists now know that a firefly’s light is a cold light. It gives off all of its power as light. It does not produce heat. A normal light bulb gives off only ten percent of its power as light. The rest of the power is wasted as heat. That is why a light bulb that has been on for a while is very hot. The firefly’s light does not feel hot like a light bulb.

Scientists have also learned that fireflies have a small built-in lantern. This special lantern is located inside a firefly’s body. To create light, a gas flows through tiny tubes. This causes the firefly to light up. A firefly can also turn its light on and off quickly. This puzzled scientists. They learned that short bursts of this gas make the firefly glow. When the gas fades, the light goes out. This process happens very quickly.

Scientists know that what they learn from fireflies will be important. Medical studies using fireflies are helping scientists fight illnesses in human beings. They have made new medicines from the chemicals used by fireflies to make light. Fireflies have also helped with new discoveries. New flashlights and flares have been made based on fireflies. These new flashlights and flares produce a cold light like a firefly. This way all the power makes the light shine. This little bug may be a pleasure to watch, but it is also an important part of our lives.

Why did the author most likely include Paragraph 4?

A. To explain how fireflies make light.        B. To describe different kinds of fireflies.

C. To show how much power fireflies use.     D. To describe why fireflies make light.

Which of these is the best choice for a heading for Paragraph 5?

A. The Cool Light of Fireflies               B. Watching Fireflies Flash

C. Understanding the Patterns               D. Learning from Fireflies

A. Paragraph 2   B. Paragraph 3     C. Paragraph 4   D. Paragraph 5

The author most likely wrote this passage in order to __.
