东华大学20__-20__学年第__学期期末试题踏实学习，弘扬正气；诚信做人，诚实考试；作弊可耻，后果自负College English Achievement TestBand 3（易班）Part I Reading Comprehension (Skimming and Scanning) (10%)Directions: In this part, there is a passage followed by ten statements. You will have 15 minutes to go over the passage quickly and decide whether each of the statements is true or false, or that the information is not given in the passage. Then mark the answer on the Answer Sheet.Renewable EnergyHow does energy use affect the environment?All forms of electricity generation have some level of environmental impact. However, clean energy technologies, including renewable energy and combined heat and power, have fewer impacts than other sources of electricity generation.To learn about the environmental impacts of electricity generation technologies, click on an energy source below.How clean is the electricity I use?In the United States, electricity is generated in many different ways, with a wide variation in environmental impact. Traditional methods of electricity production contribute to air quality problems and the risk of global climate change.With the advent of electric customer choice, many electricity customers can now choose the source of their electricity. In fact, you might now have the option of choosing cleaner, more environmentally friendly sources of energy.How can I make a difference?The energy decisions we make every day can encourage the development of new power sources, save natural resources, and help ensure that the quality of our environment is preserved. In many parts of the country, consumers now have the opportunity to choose the source of the power that is delivered to their home or business—including energy derived from renewable sources. "Renewable energy" generally refers to electricity supplied from renewable energy sources, such as wind and solar power (energy supplied by the sun), geothermal (energy created from the extreme heat contained in liquid rock—called magma（岩浆）—within the Earth's core), hydropower (energy derived from the movement of water as it flows downstream), and various forms of biomass (fuel from sources such as trees, wood and agricultural wastes and fuel crops). These energy sources are considered renewable because they are continuously replenished on the Earth.In addition, mobile sources of air pollution—such as cars, trucks, trains and lawnmowers—also contribute to air pollution nationwide and are an important source of air pollution in many urban areas.Hydrogen EnergyUsing hydrogen energy could help address many concerns facing our nation and our world. We believe hydrogen can contribute to resolving these issues for these reasons:Firstly, hydrogen can be made from a variety of domestic feedstocks like water, biomass, coal and natural gas.Second, hydrogen is non-toxic（无毒的）, non-poisonous and will not contribute to groundwater pollution. It does not create "fumes" or other harmful emissions; in fact, using hydrogen in fuel cells produces only electricity and pure water.Furthermore, hydrogen is a key enabler for the development and more widespread implementation of renewable energy technologies, resulting in cleaner and more efficient products in the marketplace.Fifty million tons of hydrogen is produced each year worldwide, with nine million tons being consumed in the U.S. The challenge is to bring hydrogen into the everyday lives of customers as they begin to use hydrogen-powered vehicles and other applications.Geothermal EnergyOur earth's interior—like the sun—provides heat energy from nature. This heat—geothermal energy—yields warmth and power that we can use without polluting the environment. Geothermal heat originates from Earth's fiery consolidation of dust and gas over 4 billion years ago. At earth's core—4,000 miles deep—temperatures may reach over 9,000 degrees F.Solar EnergySunlight, or solar energy, can be used directly for heating and lighting homes and other buildings, for generating electricity, and for hot water heating, solar cooling, and a variety of commercial and industrial uses. After the 1973 oil embargo（禁运）, there was a resurgence（复苏，波动再起）of interest in solar energy. Faced with a possibility of scarce oil resources, the United States government allocated $400 million per year, from a mere $1 million per year, for solar energy research. The expenditure is small compared to the expenditure on nuclear research. Currently, there is a need for allocating increased resources in solar research. Compared to the old forms of reducible energy (coal, oil, nuclear), solar energy offers a clean renewable form of energy. This presentation will provide an overview of the past, present and future of solar energy.Wind EnergyWe have been harnessing the wind's energy for hundreds of years. From old Holland to farms in the United States, windmills have been used for pumping water or grinding grain. Today, the windmill's modern equivalent—a wind turbine（涡轮机）—can use the wind's energy to generate electricity.Wind turbines, like windmills, are mounted on a tower to capture the most energy. At 100 feet (30 meters) or more aboveground, they can take advantage of the faster and less turbulent wind. Turbines catch the wind's energy with their propeller-like blades. Usually, two or three blades are mounted on a shaft to form a rotor（旋转部分，旋转器）.A blade acts much like an airplane wing. When the wind blows, a pocket of low-pressure air forms on the downwind side of the blade. The low-pressure air pocket then pulls the blade toward it, causing the rotor to turn. This is called lift. The force of the lift is actually much stronger than the wind's force against the front side of the blade, which is called drag. The combination of lift and drag causes the rotor to spin like a propeller, and the turning shaft spins a generator to make electricity.Wind turbines can be used as stand-alone applications, or they can be connected to a utility power grid（蓄电池电极板）or even combined with a photovoltaic（光电的）(solar cell) system. For utility-scale sources of wind energy, a large number of wind turbines are usually builtclose together to form a wind plant. Several electricity providers today use wind plants to supply power to their customers.Ocean Energy BasicsThe ocean can produce two types of energy: thermal energy from the sun's heat, and mechanical energy from the tides and waves.Oceans cover more than 70% of Earth's surface, making them the world's largest solar collectors. The sun's heat warms the surface water a lot more than the deep ocean water, and this temperature difference creates thermal energy. Just a small portion of the heat trapped in the ocean could power the world.Ocean thermal energy is used for many applications, including electricity generation. There are three types of electricity conversion systems: closed-cycle, open-cycle, and hybrid（混合的）. Closed-cycle systems use the ocean's warm surface water to vaporize a working fluid, which has a low-boiling point, such as ammonia（氨）. The vapor expands and turns a turbine. The turbine then activates a generator to produce electricity. Open-cycle systems actually boil the seawater by operating at low pressures. This produces steam that passes through a turbine/generator. And hybrid systems combine both closed-cycle and open-cycle systems.Ocean mechanical energy is quite different from ocean thermal energy. Even though the sun affects all ocean activities, tides are driven primarily by the gravitational pull of the moon, and waves are driven primarily by the winds. As a result, tides and waves are intermittent（间歇的，断断续续的）sources of energy, while ocean thermal energy is fairly constant. Also, unlike thermal energy, the electricity conversion of both tidal and wave energy usually involves mechanical devices.1.Renewable energy has no environmental impact.a. True.b. False.c.

Read the passages and answer the questions. Then, mark your answer on the Answer Sheet.Passage 1I hear many parents complain that their teenage children are rebelling. I wish it were so. At your age you ought to be growing away, from your parents. You should be learning to stand on your own feet. But take a good look at the present rebellion. It seems that teenagers are all taking the same way of showing that they disagree with their parents. Instead of striking out boldly on their own, most of them are holding one another's hands for reassurance（放心）。
