单选题Seeing the World Centuries Ago If you enjoy looking through travel books by such familiar authors as Arthur Frommer or Eugene Fodor, it will not surprise you to learn that travel writing has a long and venerable history. Almost from the earliest annals of recorded time individuals have found ready audiences for their accounts of journeys to strange and exotic locales. One of the earliest travel writers, a Greek geographer and historian named Strabo, lived around the time of Christ. Though Strabo is known to have traveled from east of the Black Seawest to Italy and as far south as Ethiopia, he also used details gleaned from other writers to extend and enliven his accounts. His multivolumed work Geography provides the only surviving account of the cities, peoples, customs, and geographical peculiarities of the whole known world of his time. Two other classic travel writers, the Italian Marco Polo and the Moroccan Ibn Battutah, lived in roughly the same time period. Marco Polo traveled to China with his father and uncle in about A. D. 1275 and remained there 16 or 17 years, visiting several other countries during his travels. When Marco returned to Italy he dictated his memoirs, including stories he had heard from others, to a scribe, with the resulting book [[ millione being an instant success. Though difficult to attest to the accuracy of all he says, Marco's book impelled Europeans to begin their great voyages of exploration. Ibn Battutah's interest in travel began on his required Muslim journey to Mecca in 1325, and during his lifetime he journeyed through all the countries where Islam held sway. His travel book the Rihlah is a personalized account of desert journeys, court intrigues, and even the effect of the Black Death in the various lands he visited. In almost 30 years of traveling it is estimated that Ibn Battutah covered more than 75,000 miles.

单选题Immigration and Problems Hundreds of thousands of people supporting immigration rights in the US filled streets all over America in early 2006. Many held signs and American flags and asked to be treated as citizens--not criminals. Many of these supported legislation from Senator John McCain that would open a path to citizenship to immigrants who were already in the country illegally. Proposed legislation from other politicians called for stricter measures--including rounding up undocumented immigrants and sending them back to their home countries. Canadian officials say that immigration applications continue to rise. Some want to keep the doors open. They need the labor. About 400,000 immigrants were allowed into the country in 2005, according to the Canadian Government statistics. However, all this growth means that cities need to adapt. Newcomers don't always make a smooth transition into jobs for which they are skilled. So industries are using mentoring programs to help new immigrants find proper jobs. With the large numbers of undocumented African immigrants arriving in the Canary Islands and showing no sign of abating, the Spanish Government has decided to get tough. There will be no more mass amnesties for illegals, and anyone coming to Spain without permission will be sent back, the government has announced. About 23,000 migrants landed on the islands in 2006, and riots have erupted in some crowded reception centers. This has promoted local authorities to appeal to the United Nations for help. France's new immigration and integration law gives the government new powers to encourage high-skilled migration. It takes effect in 2007. The new law authorizes the government to identify particular professions where France has a talent shortage. Then the government will help these identified employers find immigrant workers with needed skills or qualifications. The selected foreign employees will be granted "skills and talents" visas, valid for three years. But some concern that it'll cause brain drain in developing countries.

单选题G8 Summit Leaders of the Group of Eight Major Industrialized Nations (G8) will meet in Scotland in July this year. Representatives from China, India, Mexico, South Africa and Brazil have also been invited. Here's what the G8 leaders want from the meeting. British Prime Minister Tony Blair wants the G8 to cancel debt to the world's poorest countries. He wants them to double aid to Africa to 50 billion pounds by 2010. He has also proposed reducing subsidies to Western farmers and removing restrictions on African exports. This has not got the approval of all members because it will hurt their agricultural interests~ On climate change, Blair wants concerted (共同的 ) action by reducing carbon emissions (排放). US President George W. Bush agrees to give help to Africa. But he says he doesn't like the idea of increasing aid to countries as it will increase corruption. Bush said he would not sign an agreement to cut greenhouse gas emissions at the summit, according to media. The US is the only G8 member not to have signed the Kyoto Protocol (京都议定书). Although the US is the world's biggest polluter, Bush so far refuses to believe there is sufficient scientific data to establish beyond a doubt that there is a problem. French President Jacques Chirac supports Blair on Africa and climate change. He is determined to get the US to sign the climate change deal. German Chancellor Gerhard Schrader remains doubtful of Blair's Africa proposals. Schroder's officials have dismissed the notion that money will solve Africa's problems as "old thinking". Berlin says that African states should only receive extra money if they can prove they've solved the corruption problem. Russian President Vladimir Put in was doubtful about the value of more aid to Africa. But he has seen a way to make this work to his advantage. Put in intends to use the aid to Africa as a springboard (跳板) next year to propose aid to the former Soviet republics of Georgia, Uzbekistan, Tajikistan and Moldova. Japanese Prime Minister Juicier Koizumi's priorities are a seat on the UN Security Council, for which he will be lobbying (游说) at the summit. And he's concerned about the Democratic People's Republic of Korea's nuclear weapons programmed.
