What are they? Oh, they're robots. Have you seen a robot? Have you used a robot?

A writer first used the word robot in 1921 in a play. Since then, many languages use the word robot. A robot is a machine that does work by itself. Robots do all kinds of work for people. They can make plastic food boxes, put a box around ice cream, or even make a watch. Most robots do not look like people. Most robots stand still, and have one arm that can do different kinds of work. The arm can lift and hold things. A robot arm can use tools. For example, some robots are used to paint cars. The paint would be dangerous for people, so the robots paint the cars. Some robots can move. They have cameras for eyes, and they can feel with their robot hands. Robots can be used under the sea to find ships; some robots are used in space; some robots go into volcanoes where people cannot go.

Today, robots are helping doctors; robots are helping to make highways; robots are helping to make tall buildings; robots are helping people cut grass. What would you like a robot to do for you?

Do you think that French fries are really French? French fries are called "pommes frites" in France and they are not from France. French fries come from Belgium(比利時) originally. French fries are made of potatoes, and they are cut and fried. The fried potatoes are called French fries because they were fist seen by Americans in Belgium, but they were fried in the French way. The French way is to fry potatoes twice with a small pause in the middle.
During World War I, there were a lot of hungry American soldiers in Northern France and Belgium. They ate French fries in Belgium. After the war was over, the soldiers went back home to America. However, they missed French fries so much that they made French fries at home. That's how French fries were fist introduced to America.
French fries were called Belgian fries once, but the name was finally changed to French fries. Sometimes French fries are just called fries.
French fries are one of the most popular potato foods in America. American fast food restaurants such as McDonald's and Burger King have French fries on their menus. French fries are freshly fried, and usually served with hamburgers.
If you visit any fast food restaurant in America and order a hamburger, you will probably hear "You want fries with that?"Why don't you think about the history of French fries a little while, and say "Yes, please. Thank you."
