Ⅱ.阅读理解
The population of the United States grows larger every year. The state that has been growing the fastest is Nevada. The city that has been receiving the most new residents (居民) is Las Vegas, which lies in the desert in Southern Nevada.
Why are so many people moving to Las Vegas? First, it is easy to find a job. Tourism is the number one industry in Las Vegas, so there are many service jobs. Workers are building thousands of new homes, buildings, and schools. The children need teachers. People need to shop for food, clothing, and cars, so the stores are looking for clerks (职员). About one third of the new residents are from California, where it is more difficult to find a job. Second, Nevada has no income tax (所得税). Most states have an income tax of 2%, 4%, 5% or more. Third, many people like the weather. Even though it's very hot in the summer, the other seasons are beautiful. There are over 250 days of sunshine each year. Finally, housing is still affordable, with the price of a new

home at about $139,500. People moving from California find that this is reasonable in comparison to homes in their state.
Las Vegas is also the wedding capital of the United States. It is easier to get married in Las Vegas than in any other city in the United States. You don't need a blood test. You don't need to wait for a week for a marriage license. It's possible to get married the same day you apply for (申请) a marriage license.
Las Vegas also has problems. Because it sits in the desert, there is not enough water. Even though water is expensive, residents have not been careful in conserving water. Next, Las Vegas has serious air pollution problems. Las Vegas is surrounded (环绕) by high mountains, some as high as 10,000 feet. These mountains hold in the pollution from the cars. At times, there are warnings not to exercise outdoors. Finally, as the city becomes larger, people are traveling farther to work and the average commute (通勤) time has been increasing.
