The first robots were invented in the 1920s. Robots have appeared in many American films. In some films, they are stronger, faster and cleverer than people. In real life, robots are mainly used in factories. They do some dangerous and difficult jobs for humans. Robots also help disabled people, for example, blind people. Today many blind people have guide dogs to help them. In the future，guide dogs might be robot dogs.
One kind of robot guide dog has wheels. It moves in front of the owner. It is very clever. It knows the speed of its owner's walk. The owner wears a special belt(带子)．This belt sends instructions to the owner from the dog, such as “stop here”“turn left” or “turn right”．
In the United States, another kind of robot helps disabled people to take care of themselves in their daily lives. The robot hears the sound of its owner's voice. It follows instructions such as “turn the page” or “make a cup of coffee”．
Robots are also used in American hospitals. They can do simple jobs. At one hospital, for example, a robot takes meals from the kitchen to patients' rooms. It never gets lost because this robot has a map of the hospital in its computer memory.
Though robots can help people in many different ways, they will never take the place of humans.

A.回答问题
Sometimes the greatest inventions are invented by mistake.The greatest mistake of all time could be those delicious snacks in your corner drugstore.
One day,a woman was making chocolate cookies.When she ran out of chocolate powder (粉),she took out a chocolate bar and divided it into little pieces.She added the pieces to her cookie dough (面团) and baked (烘烤) it in the oven.She thought that the chocolate would melt (融化) in the oven and make chocolate cookies.Far from melting,the pieces of chocolate stayed hard.When she took them out of the oven,she had chocolate chip cookies!
Another accidental invention was made by Frank Epperson,an eleven-year-old boy.In 1905,Frank sat outside on a winter evening,mixing up a big bottle of powdered soda pop (苏打汽水).Frank accidentally left the bottle out during the night.When he went outside the next morning,he found the things in the bottle frozen (冷冻) with the mixing stick stuck in the middle.Frank pulled out the frozen pop and tasted it.It was delicious! That year,Frank started selling Epperson Icicles for 5 cents each.He later changed the name to Popsicles.
So, next time you drop your hamburger into your ice-cream or your cooked potatoes into your chicken soup,don’t worry! Some of the most delicious foods in the world were invented that way!
46.What was divided into pieces by the woman

Great inventions are the symbols of the social development.Some inventions are so useful that they make our life become more colorful and convenient.
My invention is a special pen.It is used for taking notes quickly.The pen has a microchip(微芯) that can store a list of common words which you will use.When you are writing, you just need to write the short forms with the pen, press a button on the pen and all the short forms will change into the actual words.Is it amazing
All in all, as middle school students, we should have scientific exploration spirit and take an active part in creating and inventing.
