【答案解析】[听力原文]
   Florida is the state where Americans and immigrants choose most to settle, shows the latest research. Population continues to move from north to south in America. Florida is expected to add five million new residents by 2030, according to the state's Office of Economic and Demographic Research. While Florida is growing, the states of Illinois, Ohio and Michigan have lost the largest numbers of residents. In 2014, Florida's population grew by over 108,000 people. The largest group packing their bags for the "Sunshine State" are young people right out of college. "Young people generally move more for education or for a job," said Stefan Rayer, a population specialist at the University of Florida. "Florida is very attractive. It has big metropolitan areas. It has good job opportunities. That's why people are moving to Florida." The state's economy is staying healthy due to the population movement. Latino and Asian immigrants are adding $150 billion worth of purchases each year.
   Q: How many new residents are expected to live in Florida by 2030?
最新的研究发现，佛罗里达州是最受美国人和移民喜爱的定居地。美国人仍不断从北方向南方迁移。据佛罗里达州的经济与人口调查办公室预测，到2030年，该州将会多出500万新居民。当佛罗里达的人口在不断增长时，伊利诺伊州、俄亥俄州及密歇根州是居民流失数量最大的几个州。2014年，佛罗里达州的人口增长量超过10.8万。带上行李来到“阳光之州”的移民中人数最多的是刚离开大学的年轻人。佛罗里达大学的人口专家斯蒂芬·拉耶说：“年轻人通常会为了求学或工作而更频繁地搬家。佛罗里达对他们来说很有吸引力。这里有大片的都市商圈，好的就业机会。这就是人们搬来佛罗里达的原因。”由于人口流动，佛罗里达的经济保持了健康发展。每年，拉美裔和亚裔的移民能给该州增加1500亿美元的消费量。
