Riches and Romance From France's Wine Harvest
September is harvest time. And with bunches of grapes swinging (摇滚) in the wind, the vineyards of southern France are getting ready to celebrate it.
The yearly wine festival is held in honour of Bacchus, the Roman god of wine. It's a fun time with parties, music, dancing, big meals and, of course, lots of wine.
French wine-making began more than 2,500 years ago. The world's oldest type of vine grows in France and always produces a good quality wine. Today France produces one fifth of the world's wine, and some of the most famous varieties.
The top wine-producing areas are Bordeaux, Burgundy and the Loire Valley. Champagne, a drink used in celebrations, is named after the place where sparkling (有气泡的)wine was first produced in 1700.
Wine is made from the juice of freshly picked grapes. It is the sugars that turn into alcohol.
Traditionally, people used to take off their shoes and crush the grapes with their bare feet to bring out the juice. Nowadays, this practice is usually carried out by machines.
Each wine producing region has its own character, based on its type of grapes and soil.
The taste of wine changes with time. Until 1850, all French champagne was sweet. Now, both wine and champagne taste slightly bitter.
The drink has always been linked with riches, romance and nobleness. Yet the French think of it in more ordinary terms.
They believe it makes daily living easier, less hurried and with fewer problems.
"All its links are with times when people are at their best, with relaxation, happiness, long slow meals and the free flow of ideas." wrote wine expert Hugh Johnson.
All French people celebrate the grape harvest every September.

【B8】

A. had they found
B. should they find
C. could they find
D. did they find

In history books, objective information about the political life of a country is presented; that is, facts about politics are given, but opinions are not expressed. Art, on the other hand, is subjective (主观的): it reflects emotions and opinions. The great Spanish painter Francisco Goya was perhaps the first truly "political" artist. In his well-known painting The Third of May, 1808, he criticized the Spanish government for its abuse (滥用) of power over people.
In the same way, art can reflect a culture's religious beliefs. For hundreds of years in Europe, religious art had been almost the only type of art that existed. Churches and other religious buildings were filled with paintings that described people and stories from the Bible. Although most people couldn't read, they could still understand the Bible stories in the pictures on church walls. By contrast, one of the main characteristics of art in the Middle East was (and still is) its absence of human and animal images. This reflects the Islamic belief that statues (雕像) are not holy.
More can be learned about a culture from a study of art history than general history because ______.

A. art history shows us nothing but the political values
B. general history only focuses on politics
C. art history gives us an insight (洞察力) into the essential qualities of a time and a place
D. general history concerns only religious beliefs, emotions and psychology
