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 built closetogether 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）。

For years, the local wildlife had been changing, and the townsfolk had noticed that the animals seemed to be evolving at an unprecedented rate. The town’s most famous naturalist, Dr.Evelyn Carter, decided to investigate this phenomenon. After months of research, she and her team uncovered the secret: a previously undiscovered mineral, known as “Evolium,” found deep within the town’s forest, was causing the animals to evolve rapidly.Dr. Carter’s findings were groundbreaking. The mineral seemed to stimulate the animals’ DNA, leading to genetic mutations that enhanced their physical and cognitive abilities. The most remarkable of these mutations was the appearance of a new species of bird, which Dr. Carter named the “Greenfield Glider.” These birds had longer wings, sharper beaks, and an enhanced abilityto navigate complex environments. The Gliders were soon becoming a symbol of hope and innovation in the town.Questions:1.What was the main focus of Dr.Evelyn Carter’s research?A) The impact of the new mineral on the local wildlife.B) The evolution of the town’s human population.C) The economic benefits of the new mineral.D) The history of the town of Greenfield.2.What effect did the Evolium mineral have on the animals in Greenfield?A) It caused them to become extinct.B) It made them more aggressive.C) It stimulated their DNA, leading to genetic mutations.D) It had no effect on their evolution.3.What is the significance of the Greenfield Glider?A) It is a rare bird species that is on the brink of extinction.B) It is the town’s mascot, representing its hope for innovation.C) It is the first bird to be discovered in the town’s history.D) It has no special features and is no different from other birds.Answers:1.A) The impact of the new mineral on the local wildlife.2.C) It stimulated their DNA, leading to genetic mutations.3.B) It is the town’s mascot, representing its hope for innovation.三、完型填空（15分）Complete the following passage with the most appropriate options.In the small town of Greenfield, the local library was facing a dilemma.

He observed that the Nile River Delta was in fact a series of sediment deposits built up in successive floods. By noting that individual floods deposit only thin layers of sediment, he was able to conclude that the Nile Delta had taken many thousands of years to build up. More important than the amount of time Herodotus computed, which turns out to be trivial compared with the age of Earth, was the notion that one could estimate ages of geologic features by determining rates of the processes responsible for such features, and then assuming the rates to be roughly constant over time. Similar applications of this concept were to be used again and again in later centuries to estimate the ages of rock formations and, in particular, of layers of sediment that had compacted and cemented to form sedimentary rocks.②It was not until the seventeenth century that attempts were madeagain to understand clues to Earth's history through the rock record. Nicolaus Steno (1638-1686) was the first to work out principles of the progressive depositing of sediment in Tuscany. However, James Hutton (1726-1797), known as the founder of modern geology, was the first to have the important insight that geologic processes are cyclic in nature. Forces associated with subterranean heat cause land to be uplifted into plateaus and mountain ranges. The effects of wind and water then break down the masses of uplifted rock, producing sediment that is transported by water downward to ultimately form layers in lakes, seashores, or even oceans. Over time, the layers become sedimentary rock. These rocks are then uplifted sometime in the future to form new mountain ranges, which exhibit the sedimentary layers (and the remains of life within those layers) of the earlier episodes of erosion and deposition.③Hutton's concept represented a remarkable insight because it unified many individual phenomena and observations into a conceptual picture of Earth’s history. With the further assumption that these geologic processes were generally no more or less vigorous than they are today, Hutton's examination of sedimentary layers led him to realize that Earth's history must be enormous, that geologic time is anabyss and human history a speck by comparison.④After Hutton, geologists tried to determine rates of sedimentation so as to estimate the age of Earth from the total length of the sedimentary or stratigraphic record. Typical numbers produced at the turn of the twentieth century were 100 million to 400 million years. These underestimated the actual age by factors of 10 to 50 because much of the sedimentary record is missing in various locations and because there is a long rock sequence that is older than half a billion years that is far less well defined in terms of fossils and less well preserved.⑤Various other techniques to estimate Earth's age fell short, and particularly noteworthy in this regard were flawed determinations of the Sun's age. It had been recognized by the German philosopher Immanuel Kant (1724-1804) that chemical reactions could not supply the tremendous amount of energy flowing from the Sun for more than about a millennium. Two physicists during the nineteenth century both came up with ages for the Sun based on the Sun's energy coming from gravitational contraction. Under the force of gravity, the compressionresulting from a collapse of the object must release energy. Ages for Earth were derived that were in the tens of millions of years, much less than the geologic estimates of the lime.⑥It was the discovery of radioactivity at the end of the nineteenth century that opened the door to determining both the Sun’s energy source and the age of Earth. From the initial work came a suite of discoveries leading to radio isotopic dating, which quickly led to the realization that Earth must be billions of years old, and to the discovery of nuclear fusion as an energy source capable of sustaining the Sun's luminosity for that amount of time. By the 1960s, both analysis of meteorites and refinements of solar evolution models converged on an age for the solar system, and hence for Earth, of 4.5 billion years.译文地球的年龄①希腊历史学家希罗多德是最早有记录的推测地球年龄的观察家之一，他生活在大约公元前480年到公元前425年。
