Frank Woolworth was born in Rodman, New York., in 1852. His family were very poor farmers, and there was never enough to eat. Frank decided he did not want to be farmer. He took a short business course, and went to work as a salesman in a large city.

Woolworth realized he had a natural skill for showing goods to attract people’s interest, but he soon learned something more important. One day his boss told him to sell some odds and ends (小商品 ) for as much as he could get. Frank put all these things on one table with a sign which said FIVE CENTS EACH. People fought and pushed to buy the things and the table was soon cleared.

Soon afterwards, Woolworth opened his own store., selling goods at five and ten cents. But he had another lesson to learn before he became successful. That is, if you want to make money by selling low-price goods, you have to buy them in large quantities directly form the factories. Once, for example, Woolworth went to Germany and placed an order for knives. The order was so large that the factory had to keep running 24 hours a day for a whole year. In this way, the price of the knives was cut down by half.

By 1919, Woolworth had over 1000 stores in the US and Canada, and opened his first store in London. He made many millions and his name became famous throughout the world. He always run his business according to strict rules, of which the most important was: “ THE CUSTOMER IS ALWAYS RIGHT.”

Passage 1 Why Is it So Difficult to Swat a Fly The brains of flies are wired to avoid the swatter, US researchers said on Thursday. At the mere hint of a threat, the insects adjust their preflight stance to flee in the opposite direction, ensuring a clean getaway, they said in a finding that helps explain why flies can so easily evade swipes from their human foes. "These movements are made very rapidly, within about 200 milliseconds, but within that time the animal determines where the threat is coming and activates a set of movements to position its legs and wings," Michael Dickinson of the California Institute of Technology said in a statement. "This illustrates how rapidly the fly’s brain can process sensory information into an appropriate motor response," said Dickinson, whose research appears in the journal Current Biology. Dickinson’s team studies this process in fruit flies using high-speed digital imaging equipment and a fancy fly swatter. In response to a threat from the front, the fly moves its middle legs forward, leans back and raises its back legs for a backward takeoff. If the threat is from the side, the fly leans the other way before takeoff. The findings offer new insight into the nervous system of the fly, and lends a few clues on how to outsmart them. Dickinson, a bioengineer, has devoted his life’s work to the study of insect flight. He has built a tiny robotic fly called Robofly and a 3-D visual flight simulator called Fly-O-Vision.
