Did you ever wonder how some of your favorite foods, products or toys came about? Believe it or not, they may have been an accident, or a failure of some other intention. Below, we found three mistakes we’re thankful for turned out to be what they are.
1. Most historians hold that the Chinese invented fireworks in the 9th century when they
discovered how to make gunpowder. Story has it that a Chinese cook accidentally mixed together what were then considered common kitchen items and noticed they burnt. When put tightly in a bamboo tube and lit, it blew up.
2. In May of 1886, a law led John Pemberton, a pharmacist（药剂师）, to rewrite the formula(配方) for "Pemberton’s French Wine Coca,” his popular headache treatment. Containing sugar instead of wine as a sweetener, the outcome became something for Coke, which was later mixed with carbonated water. His bookkeeper suggested the name Coca-Cola because he thought the two C’s would look good together, which is how what we call Coca-Cola, a world –wide drink came into being.
3. During World War II, scientists at the University of Birmingham invented the magnetron—an important heat-producing part of the microwave oven(微波炉). While working for Raytheon Corporation after the war, the American engineer Percy Spencer was testing the magnetron when a chocolate bar in his pocket melted. He went on to test other foods including popcorn kernels, and found it to be a much more efficient way to cook. In 1947 Raytheon came out with the first restaurant microwave oven, which was six feet tall and weighed 750 lbs.   
【小题1】The right time order of the three inventions, according to the passage, should be_________.

(C)                                  
The Romans built great "aqueducts" to carry fresh water from the mountains to the cities. Many of these aqueducts are still standing today. The Romans also built great pipes under the ground to carry away the sewage. In Rome, one of these sewage pipes (sewers) is still used today; it is 2,000 years old. The Roman Emperors even set up a government health service. They built the first great public hospitals in Europe, and they paid doctors to look after poor people.                    
Then the Roman Empire fell to pieces, these civilized methods of treatment disappeared from most of Europe, for more than a thousand years. People went back to the old ways. They lived in dirty conditions which helped to cause diseases（疾病）; and they asked God to cure the disease. They shut mentally sick people in prisons. Or they  burnt them alive because they were supposed to have magic powers.                
But the work of the Greek and Roman doctors was not lost. Over a thousand years
ago, they Arabs moved into many of the Mediterranean countries. They took big parts of the old Roman lands. They translated the Greek and Roman medical books into Arabic. Arab doctors themselves make many new discoveries.
When civilization(文明) at last came back to Europe, men once again translated the Greek and Roman works on medicine into Latin. Slowly－very slowly －European doctors discovered again the things that the Greeks and Romans had known so long ago. Slowly, they began to make new discoveries. They found out more about the way the body works--the way our blood goes round our bodies, the way our nerves（神经） send messages from our brains to our muscles, the way these muscles move our bodies.
