　　Renewable Energy

　　In the past century,it has been seen that the consumption of non-renewable sources of energy has caused more environmental damage than any other human activity. Electricity generated from fossil fuels such as coal and crude oil has led to high concentrations of harmful gases in the atmosphere.This has in turn led to many problems being faced today such as ozone depletion and global warming. Vehicular pollution has also been a major problem.

　　Therefore,alternative sources of energy have become very important and relevant to today's world.These sources,such as the sun and wind,can never be exhausted and therefore arc called renewable.They cause less emission and are available locally.Their use can. to a large extent,reduce chemical,radioactive, and thermalpollution. They stand out as a viable source of clean and limitless energy.These are also known as non-conventional sources of energy.Most of the renewable sources of energy are fairfy non-polluting and considered clean though biomass,a renewable source,is a major polluter indoors.

　　Solar Energy

　　Solar energy is the most readily available source of energy.It does not belong to anybody and is,therefore,free.It is also the most important of the non-conventional sources of energy because it is non-polluting and,therefore.helps in lessening the greenhouse effect.

　　Solar energy has been used since prehistoric times.but in a most primitive manner.Before 1970,some research and development was carried out in a few countries to exploit solar energy more efficiently,but most of this work remained mainly academic.After the dramatic rise in oil prices in the 1970s,several countries began to formulate extensive research and development programmes to exploit solar energy.

　　When we hang out our clothes to dry in the sun,we use the energy of the sun.In the same way, solar panels absorb the energy of the sun to provide heat for cooking and for heating water.Such systems are available in the market and are being used in homes and factories.

　　Solar energy can also be ursed to meet our electricity requirements.Through Solar Photovoltaic(SPV)cells,solar radiation gets converted into DC electricity directly.This electricity can either be used as it is orcan be stored in the battery.This stored electrical energy then can be used ac night.

　　Hydro Power

　　Hydro power is one of the best,cheapest,and cleanest source of energy,although,with big dams,there are many environmental and social problems.Small dams are,however,free from these problems.This is in fact one ofthe earliest known renewable energy sources.in the country(since the beginning of the 20th century).

　　In fact,for the last few hundred years,people living in the hills of the Himalayas have been using water mills.or chakki,to grind wheat.Besides being free from the problem of pollution.small hydropower plants arealso free from issues and controversies that are associated with the bigger projects.namely affecting the lives of thousands of people living along the banks of the rivers.destruction of large areas under forest.and seismological threats.

　　New environmental laws affected by the danger of global warming have made energy from small hydropower plants more relevant.These small hydropower piants can serve the energy needs of remote rural areas independently.The real challenge in a remote area lies in successful marketing of the energy and recovering the dues.Local industries should be encouraged to use this electricity for sustainable development.

　　It is a technology with enormous potential.which could exploit the water resources to supply energy to remote rural areas with little access to conventional energy sources.It also eliminates most of the negative environmental effects associated with large hydro projects.

　　Energy From the Sea-Ocean Thermal,Tidal and Wave Energy

　　On an averaige,the 60 million square kilometre of the tropical seas absorb solar radiation equivalent to the heat content of 245 billion barrels of oil.Scientists feel that if this energy can be tapped a large source of energy will be available to the tropical countries and to other countries as well.The process of harnessing this energy is called OTEC(ocean thermal energy conversion).It uses the temperature differences between the surface of the ocean and the depths of about lOOOm to operate a heat engine.which produces electric power.

　　Energy is also obtained from wavcs and tides.In some countries such as Japan small scale power generators run by energy from waves of the ocean,have been used as power sources for channcl marking buoys.

　　Biomass

　　Biomass is a renewable energy resource derived from the carbonaceous waste of various human and natural activities.It is derived from numerous sources,including the by-products from the timber industry.agricultural crops,raw material from the forest,major parts of household waste and wood.

　　Biomass does not add carbon dioxide to the atmosphere as it absorbs the same amount of carbon in growing as it releases when consumed as a fuel. Its advantage is that it can be used to generate electricity with the same equipment of power plants that are now burning fossil fuels.Biomass is an important source of energy and the most important fuel worldwide after coal,oil and natural gas.

　　Traditional use of biomass is more than its use in modern application.In the developed world biomass is again becoming important for applications such as combined heat and power generation.In addition,biomass energy is gaining significance as a source of clean heat for domestic heating and community heating applications.In fact in countries like Finland.USA and Sweden the per capita biomass energy used is higher than it is in India.China or in Asia.

　　Geothermal Energy

　　We live between two great sources of energy,the hot rocks beneath the surface of the earth and the sun in the sky.Our ancestors knew che value of geothermal energy;they bathed and cooked in hot springs.Today we have recognized that this resource has potential for much broader application.

　　The core of the earth is very hot and it is possible to make use of this geothermal energy(in Greek it means heat from the earth).These are areas where there are volcanoes.hot springs,and geysers,and methane under the water in the oceans and seas. n some countries,such as in the USA water is pumped from underground hot water deposits and used to heat people's houses.

　　The utilization of geothermal energy for the production of electricity dates back to the early part of thetwentieth century.For 50 years the generation of electricity from geothermal energy was confined to Italy and interest in this technology was slow co spread elsewhere.In 1943 the use of geothermal hot water was pioneered in lceland.

　　Co-generation

　　Co-generation is the concept or producing two forms of energy from one fuel.One of the forms of energy must always be heat and the other may be electricity or mechanical energy.In a conventional power plant,fuel is burnt in a boiler to generate high-pressure steam.This steam is used to drive a turbine.which in turn drives an alternator through a steam turbine to produce electric power.The exhaust steam is generally condensed to water which goes back to the boiler.

　　As the low-pressure steam has a large quantum of heat which is lost in the process of condensing,the efficiency of conventional power plants is only around 35%.In a cogeneration plant,very high efficiency levels,in the range of 75%-90%,can be reached.This is so,because the low-pressure exhaust steam coming out of th turbine is not condensed,but used for heating purposes in factories or houses.

　　Since co-generation can meet both power and heat needs, it has otber advantages as well in the form of significant cost savings for the plant and reduction in emissions of pollutants due to reduced fuel consumption.

　　In department stores and closets all over the world. they are waiting. Their outward appearance seems rather appealing because they come in a variety of styles, textures. and colors. But they are ultimately the biggest deception that exists in the fashion industry today. What are they? They are high heels—a woman's worst enemy (whether she knows it or not). High heel shoes are the downfall of modem society. Fashion myths have led women to believe that they are more beautiful or sophisticated for wearing heels, but in reality, heels succeed in posing short as well as long term hardships. Women should fight the high heel industryby refusing to use or purchase them in order to save the world from unnecessary physical and psychologicalsuffering.

　　For the sake of fairness. it must be noted that there is a positive side to high heels. First. heels are excellent for aerating (使通气) lawns. Anyone who has ever worn heels on grass knows what I am talking about. A simple trip around the yard in a pair of those babies eliminates all need to call for a lawn care specialist. and provides the perfect-sized holes to give any lawn oxygen without all those messy chunks of dirt lying around. Second, heels are quite functional for defense against oncoming enemies. who can easily be scared away By threatening them with a pair of these sharp, deadly fashion accessories.

　　Regardless of such practical uses for heels, the fact remains that wearing high heels is harmful to one's physical health. Talk to any podiatrist (足病医生), and you will hear that the majority of their business comes from high-heel-wearing women. High heels are known to cause problems such as deformed feetand tom toenails. The ask of severe back problems and twisted or broken ankles is three times higher for a high heelwearer than for a flat shoe wearer. Wearing heels also creates che threat of getting a heel caught in a sidewalk crack or a sewer-grate (阴沟栅) and being thrown to the ground-possibly breaking a nose. back, or neck. And of course, after wearing heels for a day. any woman knows she can look forward to a night of painas she tries to comfort her swollen, aching feel.

　　Divorce doesn't necessarily make adults happy. But toughing it out in an unhappy marriage until it turns around just might do, a new study says.

　　The research identified happy and unhappy spouses. culled (选出 ) from a national database. Of the unhappypartners who divorced. about half were happy five years later. But unhappy spouses who stuck it out often did better. About two-thirds were happy five years later. Study results contradict what seems to be commonsense, says David Blankenhorn of the Institute for American Values, a think-tank on the family. The institute helped sponsor the research leam based at the University of Chicago. Findings will be presented in Arlington, Va.. at the "Smart Marriage" conference. sponsored by the Coalition for Marriage. Families and Couples Education.

　　The study looked at data on 5,232 married adults from the National Survey of Families and Households. It included .64.5 who were unhappy. The adults in the national sample were analyzed through 13 measures of psychological well being. Within the five years, 167 of the unhappy were divorced or separated and 478 stayedmarried.

　　Divorce didn't reduce symptoms of depression, raise self-esteem or increase sense of mastery compared withthose who stayed married, the report says.

　　Results were controlled for factors including race, age, gender and income. Staying married did not tend to trap unhappy spouses in violent relationships. What helped the unhappy married turn things around? To supplement the formal study data, the research team asked professional firms to recruit focus groups totaling 55 adults who were "marriage survivors". All had moved from unhappy to happy marriages. These 55 once-discontented married felt their unions got better via one of three routes, the report says:

　　Marital endurance. "Wich time, job situations improved, children got older or better. or chronic ongoing problems got put into new perspective." Partners did not work on their marriages.

　　Marital work. Spouses actively worked "to solve problems, change behavior of improve communication".

　　Personal change. Partners found "alternative ways to improve their own happiness and build a good and happy life despite a mediocre marriage." In effect the unhappy partner changed.1. According to David Blankenhorn. people commonly believe that________.

　　A) divorce is a better solution to an unhappy marriage than staying together

　　B) divorce is not necessarily the only solution to an unhappy marriage

　　C) keeping an unhappy marriage needs much courage and endurance

　　D) to end an unhappy marriage or not is a tough decision for the spouses

　　2. Which of the following is true about the research under discussion?

　　A) It was conducted by che Institute for the American Values headed by David Blankenhorn.

　　B) It was sponsored by the Coalition for Marriage, Families and Couples Education.

　　C) Its subjects were chosen from a national database based at the University of Chicago.

　　D) Its report will be included in the schedule of the "Smart Marriage"conference.

　　3. The 13 measures of psychological well-being are used to_______.

　　A) serve as the standards for choosing the subjects of the research

　　B) serve as the ways to help adults to get over their unhappy marriage

　　C) examine all the 5232 married adults

　　D) examine all the adults in the database

　　4. The author's attitude towards divorce may best be described as ________".

　　A) critical

　　B) impersonal

　　C) arbitrary

　　D) scornful

　　5. According to the report, chose unhappily-wedded may not survive their marriage by_______.
