[1]All people have dreams and they obey the rule that if you can dream it, you can achieve it! Here are four goals for people to reach a perfect life in their future.
[2]The first goal common to all of us in health and energy. We all want to be healthy and fit, to have high levels of energy and to live free of pain and illness. Today, with the incredible advances in medical science, the quality of our health and fitness, and our lifespan, is largely determined by design, not by chance. People with excellent health habits are far healthier, have more energy, and live longer and better than people who have poor health habits. Remember that health is not everything, but without health everything is nothing!
[3]The second goal that we all have in common is to enjoy excellent relationships – intimate, personal or social – with the people we like and respect, and who                         is turn. Fully 85% of your happiness will be determined by the quality of your relationships at each stage, and in each area, of your life. How well you get along with people, and how much they     , have more impact on the quality of your life than perhaps any other factor.
The third common goal is to do work that we enjoy, to do it well, and to be well paid for it. You want to be able to get and keep the job you want, to get paid more and promoted faster. You want to earn the very most that is possible for you at each stage of your career, whatever you do.
The fourth goal we all have in common is to achieve financial independence. You want to reach the point in life where you have enough money so that you never have any financial worries. You want to be completely free of them. You want to be able to order dinner in a restaurant without referring to the price listing to determine what you want to eat.

Humankind has tried to improve its standard of living since the very beginning of civilization. Back then, as well as today, providing food and security was the basic task for a person. However, nowadays the range of required goods has expanded significantly. People feel the need for not only some primary things, such as a piece of bread and a roof over their heads, but also for various facilities and luxuries. Providing humanity with these things is connected to the use of natural resources, which requires energy. In turn, the common sources of energy we use today cause pollution, so economic growth is almost inevitably associated with environmental damage.
Economic growth is the increase in numbers of goods and services produced over time by an economy, and it's calculated in terms of real Gross Domestic Product (GDP). Before growth is calculated, inflation(通货膨胀) is adjusted in order to take into account its misleading effect on the price of goods and services. Economic growth can also be explained as the increase in expected output, which results from an increase in actual output, or total demand.
There are certain aspects of economic growth which affect the environment. The first of these is the fact that in order to produce more goods and products, at a faster rate, the construction of large industrial plants is required. These plants produce a lot of waste, leading to the pollution of water and the atmosphere, which may cause negative long- term health effects to nearby populations of animals, or people. They also lead to global warming.
Industrial manufacturing leads to the constantly increasing energy consumption. The traditional energy sources, which are commonly used nowadays, are considered to be the greatest polluters to the environment. There also exist so-called eco-friendly sources of energy. They are sometimes preferred but replacing the traditional sources with them also requires time, during which people have to make some sacrifices to support these undertakings.
In order to produce economically practical energy, a sometimes significant transformation of the natural site is often inevitable. This is expensive and, has harmful effects on the environment. Application of wind energy would Block airflows' natural speed, which is the reason for their decrease in strength, after crossing the windmill. Consequently, the pressure balance that is brought about by this current will be affected, and it is important to remember that the environment and weather conditions are directly affected by atmospheric pressure.
For these reasons, bringing about economic growth without resulting in any environmental damage is impossible.
【小题1】What does the passage mainly talk about?

A．Pollution caused by plant construction

B．Effects of windmills on the environment

C．Economic growth and human civilization

D．Economic growth and environmental damage

【小题2】According to the passage, the author holds the opinion that ____.

A．economic growth should be calculated in terms of GDP

B．use of natural resources causes no damage to the environment

C．industrial manufacturing may cause damage to the environment

D．a windmill is a perfect way to produce economically practical energy

【小题3】Which of the following shows the structure of the passage?

CP (Central Point) P (Point) Sp (Sub-point次要点) C (Conclusion)

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. The type of home you have is another. Things like insulation(绝缘) 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. And when Mother Nature says 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 begin an endless source of energy, the use of the sun has other advantages as well. The sun doesn’t offer as many problems as other energy sources. For example, fossil fuel plants add to already high pollution levels. With sola 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 this 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. Solar energy is now in its infancy. It could soon grow to become a major part of our nation’s energy supply.

57. Which statement best expresses the main idea?

A. Something about Solar Energy and Pollution. B. Solar Energy.

C. Energy and Pollution D. Energy and Money

58. Solar energy can help us save ____.

A. the earth and nature resources B. mother nature

B. Energy from natural gas would not pollute our living environment.

C. Energy from the sun would not pollute our living environment.

60. Solar energy is in its infancy, ____.

A. but it will be considered as an important part of our nation’s energy supply

B. yet we will build more power plants

C. and the supply of electricity will be rationed

D. but we don’t need practice energy rationing now
