单选题Different Tastes For Vacation People like different kinds of vacations. Some go outside. Others like to stay at a hotel in an exciting city. They go shopping all day and go dancing all night. Or maybe they go sightseeing to places such as Disneyland, the Tai Mahan or the Louver. Some people are bored with sightseeing trips. They don't want to be "tourists". They want to have an adventure, to learn something and maybe help people too. How can they do this? Some travel companies and environmental groups are planning special adventures. Sometimes these trips are difficult and full of hardships, but they're a lot of fun. One organization, Earth Watch, sends small groups of volunteers to different parts of the world. Some volunteers spend two weeks and study the environment. Others work with animals. Others learn about people of the past. Would you like an adventure in the Far North? A team of volunteers is leaving from Mormons, Russia. The leader of this trip is a professor from Alaska. He's worried about chemicals from factories. He and the volunteers will study this pollution in the environment. If you like exercise and cold weather, this is a good trip for you. Volunteers need ski sixteen kilometers every day. Do you enjoy ocean animals? You can spend two to four weeks in Hawaii. There, you can teach language to dolphins. Dolphins can follow orders such as "Bring me the large ball." They also understand opposites. How much more can they understand? It will be exciting to learn about these intelligent animals. Another study trip goes to Washington State and follows orcas. We call them "Killer Whale", but they're really dolphins-- the largest kind of dolphin. This beautiful animal travels together in family groups. They move through the ocean with their mothers, grandmothers and great-grandmothers. Ocean pollution is chasing their lives. Earth Watch is studying how this happens. Are you interested in history? Then Greece is the place for your adventure. Thirty-five hundred years ago a volcano exploded there, on Santorum. This explosion was more terrible than Karate or Mount Saint Helens. But today we know a lot about the way of life of the people from that time. There are houses, kitchens, and paintings as interesting as those in Pompeii. Today teams of volunteers are learning more about people from the past. Do you want a very different vacation? Do you want to travel far, work hard and learn a lot? Then an Earth Watch vacation is for you.

单选题 Government Policies and Economy While he was off on his 1978 tour, Americans were becoming disgusted with their lot as all "emerging second-class nation", Wilson says. They began to see that incentives had to be restored to the economy. For instance, the capital gains tax was cut, an extraordinary turn-about. If it had been predicted before he went away in May, he would have said it was simply inconceivable as inconceivable as the prospect of Resorts going up 1,000 percent. This momentous transformation in the U.S. should soon bring about a huge bull market. In the 1940s and 19S0s, the last time price earning multiples were at these low levels, the investing public expected that there would be another great postwar depression. Instead, after the beginning of 1953 it became apparent that there would not be one, and price-earnings multiples got so low this time that investors felt that the country was drifting into socialism. That drift, however, may be reversing direction. Wilson believes that the bankruptcy of New York City means the discrediting of big government, that as a result there will be less government, and that things in general will go much better. From 1980's depressed levels the market could rise to twenty times doubled earnings or almost fivefold in five to seven years. Wilson believes that he'll be worth hundreds of millions of dollars before it's over.
