到目前为止，全国已有7.8万名“村官”，小杨就是其中的一位。大学一毕业，小杨打破传统观念，只身来到千里之外的一个乡村任村委会主任助理。任职期间，在村党支部和村委会的领导下，她走访农户，宣传党和政府的有关方针和政策，传授农业科技知识，协助主任处理一系列村务。她刻苦学习雕刻知识，与该村艺人共同努力，使该村濒临失传的木雕工艺重放异彩，并将原先小打小闹的木雕品发展为人人喜爱的旅游纪念品。短短两年，该村的社会风气明显好转，村民的钱包鼓了起来。因此，“村官”小杨得到了领导和村民的一致好评。小杨自己也认为当“村官”是一个正确的选择。

结合材料，运用“实现人生的价值”的有关知识，说明“村官”小杨在乡村的精彩人生给我们的启示。

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.
