B
Today, the bicycle is the primary method of transportation for the human race. About 1.6 billion bicycles are in use around the world --- in big cities, along remote country lanes, and in the smallest villages ---and hundreds of millions of bikes are produced every year to meet the continuing demand for cheap wheeled transport.
Yet the bicycle is hardly a new vision of how humans move around. Historians speculate(猜测) about Leonardo da Vinci’s 1940s drawings and a 1580s stained glass window in England that appear to describe a two-wheeler. The first widely recognized two-wheeler in actual use, however, was the pedal-less Celerifere, a toy of the French upper class in the 1970s. The more famous Draisienne followed that toy in 1816, still without pedals. The front wheel could be steered, and this two-wheeler was eventually mass-produced in Europe, particularly in England. Ernest Michaux added cranks(曲轴) to the two-wheeler in 1855, which started a revolution in human transportation --- the Velocipede.
By 1870, complicated metal Velocipede were in production in Europe and the United States. Over time, they gave way to the “Ordinary” or high-wheeler. The Ordinary was the beginning of the heyday(全盛期) of bicycling. It was speedy and capable of long trips on poor roads, so it was soon in widespread use. At that time a skilled person might earn 25 cents an hour in wages, but a good Ordinary sold for $75 to $125, making it more expensive than building a house. Nevertheless, they sold at a furious pace.
Ordinaries had a big problem, however. When the front wheel came up against any obstacle that it could not roll over, the bike simply threw the rider headfirst onto the ground. Called a “header”, this characteristic problem inspired the “safety bicycle” in the 1980s. With two wheels of equal size, plus a roller chain(齿轮) transmission, the safety bicycle was with a slight adaptation, they attracted thousands of women to cycling. Many historians point to the safety bicycle as the beginning of women’s rights.
In England, in 1909, the Raleigh bicycle, equipped with a 3-speed hub, started to be produced. In the 1930s, British-built “lightweight” bicycles, suitable for the packed earth of country roads, were being imported into the United States. The early 1980s saw the creation of the “Freestyle” or trick bicycle. And in the late 1990s, the road bike and the mountain bike proved to be the dominant machines of the decade.
Today, the bicycle continues to be the most energy and cost-efficient transportation device in the world.

One day, President Lincoln went to a party. At the gathering, a man called Douglas was repeatedly talking about Lincoln’s low position in life and saying that he first met Lincoln when he was a shop assistant at a village shop. Finally he said, “And Mr. Lincoln was a very good waiter too.”
People burst into laughter, but they quieted down when Mr. Lincoln said quietly.
“Gentlemen, what Mr. Douglas has said is true. I did keep a grocery(杂货店), and I did sell cotton, candles and cigars, and sometimes whiskey(威士忌酒). But I remember that in those days Mr. Douglas was one of my best customers. I often stood on one side of the counter(柜台) and sold whiskey to Mr. Douglas on the other side, but the difference between us now is: I have left my side of the counter, but Mr. Douglas still sticks to his as firmly as ever.”

In nature, you may see many insects and animals of different colors. Have you ever wondered why?
Locusts (蝗虫)are super delicious food for birds, but it is not always an easy job for birds to catch them. It is neither because locusts are good jumpers or runners nor because they are smarter than their enemies(敌人). The reason is that the colors of locusts change with the colors of crops (庄稼). When crops are young, locusts look green. But when autumn comes, locusts change to the yellow and brown color as crops do.
Brown bears, tigers and other animals move quietly through forests. They can’t be seen easily by their enemies. This is because they have colors similar to the trees. For the same reason, polar bears that live on a land of snow and ice are white. Butterflies (蝴蝶)and bees living among the flowers are colorful like flowers. Soil insects are mostly dark-colored and they live under the soil in a dark and wet environment. However, insects with colors different from plants can easily be found and eaten by others. So in order to survive, they have to hide themselves in the daytime and appear only at night.
Have you ever noticed some even stranger acts(行为)? The ink fish in the sea can send out some very black ink when it faces danger. As the ink spreads over, its enemies will find themselves in a dark world. At the same time the ink fish immediately swims away. That is how it keeps itself safe though it is not strong at all.

A.do not have bright colors
