4、Puerto Rico may be part of the USA but its music and dance is a mixture of both Spanish and American rhythms（节奏）. The country, as a result, is a mixture of the new and the old. It exhibits the open American way of life yet remains the more formal Spanish influences（影响）. This is showed in the buildings, not just the difference between the old and the modern in urban areas but also in the countryside, where older buildings sit side by side with schools and houses. It is found in the cooking, too many fast food restaurants together with local cooking which has its roots in the mixture of culture of all the Caribbean and in the music --- rock music is played in beach holiday centers but in the hilly center, Puerto Rican music can be heard. Old volcanic mountains, long motionless, take up a large part of the center, with the highest peak, Cerro de Punta, at 1,338 metre in the Cordillera Central. The mountains are surrounded by a coastal plain with the Atlantic shore beaches cooled all the year round by trade winds.

The population is 3.8 million, of which about 1.5 million live in San Juan, although about another two million Puerto Ricans live in the USA. The average life is 73.8 years and GDP per person is US$12, 212, the highest in Latin America, although not up to the level of mainland USA. The people are largely a mixture of Amerindian, Taino-Arawak, Spanish and African. Most Puerto Ricans do not speak English and less than 30% speak it well. The people are very friendly and hospitable but there is law-breaking action, linked to drugs and unemployment.

3、Solar energy for your home is coming. It can help you as a single home owner. It can help the whole country as well. Whether or not solar energy can save your money depends on many things. Where you live is one factor and the type of home you have is another. Things like insulation (绝缘材料), present energy costs, and the type of system you buy are added factors.

Using solar energy can help save our precious fuel. As you know, our supplies of oil and gas are very limited. There is just not enough on hand to meet all our future energy needs. Sooner or later Mother Nature will say that's all. The only way we can delay hearing those words is by starting to save energy now and by using other sources, like the sun.

We won't have to worry about the sun's running out of energy for another several billion years or so. Besides, the sun doesn't offer as many problems as other energy sources. For example, fossil fuel(矿物燃料) adds to already high pollution levels. With solar energy, we will still need sources of energy, but we won't need as much. That means we can cut down on our pollution problems.

With all these good points, why don't we use more solar power? There are many reasons for this. The biggest reason is money. Until now, it was just not practical for a home owner to put in a solar unit. There were cheaper sources of energy.

All that is changing now. Solar costs are starting to equal the costs of oil and electricity. Experts say that gas, oil and electricity prices will continue to rise. The demand for electricity is increasing rapidly. But new power plants will use more gas, oil or coal. Already in some places the supply of electricity is being rationed (限量供应). Solar energy is now in its infancy (初期). It could soon grow to become a major part of our nation's energy supply.
