单选题{{B}}第二篇{{/B}} {{B}}New Foods and the New World{{/B}} 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 (可可树) 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 (饥荒)" of 1845—1846, and thousands more were forced to leave their homeland and move 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 "wide-awake" feeling that one-third of the world's population now starts the day with.

单选题Trying to Find a Partner One of the most striking findings of a recent poll in the UK is that of the people interviewed, one in two believes that it is becoming more difficult to meet someone to start a family with. Why are many finding it increasingly difficult to start and sustain intimate relationships? Does modern life really make it harder to fall in love? Or are we making it harder for ourselves? It is certainly the case today that contemporary couples benefit in different ways from relationships. Women no longer rely upon partners for economic security or status. A man doesn't expect his spouse to be in sole charge of running his household and raising his children. But perhaps the knowledge that we can live perfectly well without a partnership means that it takes much more to persuade people to abandon their independence. In theory, finding a partner should be much simpler these days. Only a few generations ago, your choice of soul mate(心上人)was constrained(限制) by geography, social convention and family tradition. Although it was never explicit, many marriages were essentially arranged. Now those barriers have been broken down. You can approach a builder or a brain surgeon in any bar in any city on any given evening. When the world is your oyster(牡蛎), you surely have a better chance of finding a pearl. But it seems that the old conventions have been replaced by an even tighter constraint: the tyranny of choice. The expectations of partners are inflated (提高) to an unmanageable degree : good looks, impressive salary, kind to grandmother, and right socks. There is no room for error in the first impression. We think that a relationship can be perfect. If it isn't, it is disposable. We work to protect ourselves against future heartache and don't put in the hard emotional labor needed to build a strong relationship. Of course, this is complicated by realities. The cost of housing and child-rearing creates pressure to have a stable income and career before a life partnership.

单选题"Ice Explorer" Ready For Launch The European space agency's mission to assess the state of the world's ice cover is likely to launch in February. The Cryosat -2 spacecraft will go into orbit on a Dnepr rocket from Baikonur, Kazakhstan, the agency has announced. The satellite is a rebuild of the mission that was destroyed in 2005 when its launcher failed just minutes into its flight. Cryosat - 2's radar instrument will make detailed maps of the ice that covers both sea and land at the poles. Data from other satellites has already indicated that some of this cover is diminishing at a rapid rate in response to climate change, with the biggest melting occurring in the Arctic. The completed Cryosat -2 is undergoing final checks here at the IABG technical centre in Ottobrunn near Munich, Germany, a test facility used by satellite manafacturers. It was hoped Cryosat -2 could launch in December, but the flight has been delayed now until next year. Esa said there was a queue of missions waiting for a ride on the Russian - Ukrainian Dnepr rocket. "Yes, it's frustrating, hut that's bow it is," conceded Volker Liebig, Esa's director of Earth observation pragrammes. "On the other hand it gives us a little bit more time to [ train and prepare the ground team ], which means when we do get into orbit we'll be ready to start operations rapidly because of all the work we've dobe in advance. " Mission managers are targeting 28 February for a launch. The inability of the agency to loft its satellites at a time of its choosing should become less of a problem when it has access to its new Vega rocket. Vega, which will operate out of Europe's Kourou spaceport in French Guiana, has been designed specifically to carry small institutional payloads such as Cryosat to odfit. However, the rocket is not expected to enter into service until the middle of next year. Cryosat - 2 is part of Esa's Earth Explorer programme - seven spacecraft that will do innovative science in obtaining data on issues of pressing environmental concern. The first in the series, Goce ( Gravity Field and Steadyr - State Ocean Circulation ), was launched in March.

单选题The Cherokee Nation Long before the white man came to America, the land belonged to the American Indian nations. The nation of the Cherokees lived in what is now the southeastern part of the United States. After the white man came, the Cherokees copied many of their ways. One Cherokee named Sequoyah saw how important reading and writing was to the white man. He decided to invent a way to write down the spoken Cherokee language. He began by making word pictures. For each word he drew a picture. But that proved impossible—there were just too many words. Then he took the 85 sounds that made up the language. Using his own imagination and an English spelling book, Sequoyah invented a sign for each sound. His alphabet proved amazingly easy to learn. Before long, many Cherokees knew how to read and write in their own language. By 1828, they were even printing their own newspaper. In 1830, the US Congress passed a law. It allowed the government to remove Indians from their lands. The Cherokees refused to go. They had lived on their lands for centuries. It belonged to them. Why should they go to a strange land far beyond the Mississippi river? The army was sent to drive the Cherokees out. Soldiers surrounded their villages and marched them at gunpoint into the western territory. The sick, the old and the small children went in carts, along with their belongings. The rest of the people marched on foot or rode on horseback. It was November, yet many of them still wore their summer clothes. Cold and hungry, the Cherokees were quickly exhausted by the hardships of the journey. Many dropped dead and were buried by the roadside. When the last group arrived in their new home in March 1839, more than 4,000 had died. It was indeed a march of death.

单选题Animal"s "Sixth Sense" A tsunami was triggered by an earthquake in the Indian Ocean in December, 2004. It killed tens of thousands of people in Asia and East Africa. Wild animals, 1 , seem to have escaped that terrible tsunami. This phenomenon adds weight to notions that they possess a "sixth sense" for 2 , experts said. Sri Lankan wildlife officials have said the giant waves that killed over 24,000 people along the Indian Ocean island"s coast clearly 3 wild beasts, with no dead animals found. "No elephants are dead, not 4 a dead rabbit. I think animals can 5 disaster. They have a sixth sense. They know when things are happening," H. D. Ratnayake, deputy director of Sri Lanka"s Wildlife Department, said about one month after the tsunami attack. The 6 washed floodwaters up to 2 miles inland at Yala National Park in the ravaged southeast, Sri Lanka"s biggest wildlife 7 and home to hundreds of wild elephants and several leopards. "There has been a lot of 8 evidence about dogs barking or birds migrating before volcanic eruptions or earthquakes. But it has not been proven," said Matthew van Lierop, an animal behavior 9 at Johannesburg Zoo. "There have been no 10 studies because you can"t really test it in a lab or field setting," he told Reuters. Other authorities concurred with this 11 . "Wildlife seem to be able to pick up certain 12 , especially birds... there are many reports of birds detecting impending disasters," said Clive Walker, who has written several books on African wildlife. Animals 13 rely on the known senses such as smell or hearing to avoid danger such as predators. The notion of an animal "sixth sense"—or 14 other mythical power is an enduring one which the evidence on Sri Lanka"s ravaged coast is likely to add to. The Romans saw owls 15 omens of impending disaster and many ancient cultures viewed elephants as sacred animals endowed with special power or attributes.
