    Work your brain!

    　　Between 2 and 3 pounds of wonder, it controls everything we say, do or think, who we are and what we care about．The way we walk or laugh or figure out things．What we like and the talents we possess．How we see and talk and run and jump and process our food．

    　　The brain uses 20 percent of our body's oxygen and 20 percent of its blood．Somewhere within its protein, fat, 100,000 miles of blood vessels(血管)and 100 billion nerve cells, it helps us remember where we put our gym shoes．Change our temperature so we don't die because of the heat or cold．Speed us up or slow us down．Help us choose between orange juice or orange-flavored drinks．

    　　Its complexity are stunning, far beyond anything most of us can imagine．To keep this work of art as smooth as possible we need to eat right, exercise and keep mentally stimulated(刺激的)．

    　　Good nutrition helps brain cells communicate with each other．Exercise stimulates a hormone(荷尔蒙)in our brain that improves memory．Mental stimulation keeps you sharp even as you age．

    　　“It's very important that we tell people to be physically active and mentally active,” said neurologist Malcolm Stewart．

    　　“People cannot stop aging, but you're able to reduce the damage; you're able to keep the function up．”

    　　People generally use spices(香料)every day when preparing meals．Most of these spices are readily available in local supermarkets．However, in the 15th and 16th centuries, spices were as valuable as gold or diamonds．Spices are small plants or parts of plants, such as ginger, pepper, vanilla, and cinnamon, which are used to add flavor to our food．　　1　　 Such a use for spices actually goes all the way back to Roman times．The Romans used spices such as cumin and coriander to help preserve food．

    　　The spices came to Europe from countries to the east, such as the islands in the East Indies, Sri Lanka, and India．　　2　　 Because of the long journeys involved, they were very expensive．

    　　European sailors began to look for routes to these countries themselves in order to bring back the spices by sea．In 1498, a Portuguese explorer named Vasco Da Gama reached an East Indies island called Calicut．　　3　　 In 1519, another Spanish explorer, Ferdinand Magellan, found a new trade route by sailing west across the Atlantic Ocean, around the southern tips of both South America and Africa, and back to Europe．

    　　　　4　　 Portugal was the leader until the end of the 16th century．Spain was in control during much of the next 100 years．Then, Holland took over．The Dutch controlled the East Indies, but, in 1780, England defeated them in a famous war．　　5　　 They treated the people there badly and made them submit to the British government．

    　　India finally became independent from Britain in the 1940s．Today, it is still called“the land of spices”．In fact, at present India produces 2.5 million tons of spices each year and produced more types of spices than any other country．

    A．For centuries, Arab traders had carried the spices over land and sold them to European countries．

    B．For the next four centuries, Western countries raced each other for control of the spice trade in these new countries, which they called the“New World．”

    C．Though they might not be as valuable today as gold or diamonds, spices are still big business around the globe．

    D．Six years earlier, Spanish explorer Christopher Columbus had been looking for spices when he discovered America．

    E．The English then moved from the islands into India．

    F．The history of spice is almost as old as human civilization．

    G．In those times, spices also helped keep meat from spoiling．
