单选题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. 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, a country in Africa. It was first made into a drink by Arabs during the 1400’s. According to an Arabic legend, coffee was discovered when a person named Kaldi noticed that his goats were attracted to the red berries on a coffee bush. He tried one and experienced the “wideawake” feeling that one-third of the world’s population now starts the day with. In the last 500 years, nothing about people—not their clothes, ideas, or languages—has changed as much as what they eat.

单选题 Moving far more quickly than many had thought likely or possible, lawmakers in the 10-member House-Senate committee announced the agreement after less than 24 hours of negotiations. Senate Majority Leader Harry Reid: 'Like any negotiation, this involved give and take, and if you don't mind my saying so that is an understatement.' The agreement drops the total to ＄789 billion, while both Senate and House-passed measures exceeded ＄800 billion. A combination of low and middle income tax cuts, malting up about 35 percent of the bill, and domestic spending, its supporters say it meets President Barack Obama's goal of creating or saving as many as 4 million jobs. Susan Collins of Maine was among only 3 moderate Senate Republicans who joined the Democratic majority there. She says money trimmed from the bill reflects an effort to focus it more sharply to help the economy. 'It is a fiscally-responsible number that reflects our efforts to truly focus this bill on programs, and policies and tax relief that will help turn our economy around, create jobs and provide relief to the families of our country,' she said. Collins also pointed out the agreement increases spending on infrastructure projects, more than ＄150 billion in the proposed measure. Republican opponents kept up their criticisms, primarily that the measure contains untargeted spending and not the right level of tax relief. House Republican leader John Boehner voiced disappointment with the agreement, repeating his assertion that the measure will not create jobs quickly enough. 'It appears that they have made a bad bill worse by reducing the amount of tax relief for American families and small businesses, and adding more wasteful Washington spending,' he said. But Senator Arlen Specter, another moderate Republican who worked with Democrats, said action was required. 'This is obviously a very difficult vote in view of the large deficit and national debt which we have, but I believe it is indispensable, that strong action be taken,' he said. White House aides, including Chief of Staff Rahm Emanuel, joined in the negotiations on Capitol Hill. Lawmakers behind the agreement hope a final conference report will be ready in the next 2 days that the House and Senate will vote on. Approval would send the legislation to President Obama for signature. An eventual Senate vote is expected to mirror earlier results in which majority Democrats, with help from the 3 Republicans, achieved the 60 votes needed to overcome any procedural block. It remains to be seen how a vote will turn out in the House, where no Republicans supported a House-passed measure, but where Democrats hold a strong enough majority to pass measures easily. House Republican leaders declined to predict Wednesday how many in their party might support final legislation.
