单选题(79) In the last 500 years, nothing about people--not their clothes, ideas, or languages--has changed as much as what they eat. The original chocolate drink was made from the seeds of the cocoa tree by South American Indians. The Spanish introduced it to the rest of the world during the 1500's. And although it was very expensive, it quickly became fashionable. In London shops where chocolate drinks were served became important meeting places. Some still exist today. The potato is also from the New World. Around 1600, the Spanish brought it from Peru to Europe, where it soon was widely grown. (80) Ireland became so dependent on it that thousands of Irish people starved when the crop failed during the "Potato Famine" of 1845--1846, and thousands more were forced to emigrate to America. There are many other foods that have traveled from South America to the Old World. But some others went in the opposite direction. Brazil is now the World's largest grower of coffee, and coffee is an important crop in Colombia and other South American countries. But it is native to Ethiopia. It was first made into a drink by Arabs during the 1400's. According to an Arabic legend, coffee was discovered when a goatherd name Kaldi noticed that his goats were attracted to the red berries on a coffee bush. He tried one and experienced the "wide-awake" feeling that one-third of the world's population now starts the day with.

单选题A handwritten note from Albert Einstein sold for more than $1.5 million at an auction(拍卖 会). He gave the note to a hotel porter in Japan in 1922. Einstein was not carrying money when the porter came to his room. (78) He was unable to give a cash tip, as a guest normally would. Instead he gave a tip on how to live life. "A calm and modest life brings more happiness than pursuit of success combined with constant restlessness," Einstein wrote. The note was written in German. It was written on notepaper from the Imperial Hotel in Ginza, Tokyo, where Einstein was delivering a series of lectures. He was traveling to Asia when news that he had won the Nobel Prize for Physics reached him via telegraph. Einstein was unable to attend the prize-giving ceremony in Stockholm. Gal Wiener is head of the auction house in Jerusalem, Israel, where the note was sold. He said Einstein told the hotel porter to keep the note since it "will probably be worth more than a regular tip". Bidding(拍卖中的出价) on the note began at $ 2,000. It was expected to sell for no more than $ 8,000. But 25 minutes later, the auction house made the major sale. (79) A second Einstein note was also sold at the auction . It went for more than $200,000. "Where there"s a will, there"s a way," the note says. The identity of the person or group that sold the notes has not been made public. Nor has that of the buyer or buyers.
