题目内容

　　Biomass energy（生物能）,often forgotten as a promising alternative（替代物）to oil,received its day in the sun with the gathering of the Bio-Energy World Congress and Exposition in Atlanta,Georgia,late in April,1990．Nearly 1,700 scientists,businessmen,and policy-makers,one-quarter from the foreign nations,gathered for a week to discuss various means of squeezing usable energy out of trees,crops,manure,seaweed,algae,and urban waste．Biomass in the United States contributes 2.5 percent of the total supply,but this amount can be doubled by 2000 and then doubled again by the year 2010．

　　Eight percent of Sweden's energy supply,for example,is presently coming from wood bark and pulp remainings,Sweden intends to raise this percentage by more intensive harvesting of waste food lying around in forests,and through the planting of so-called energy forests of fast-growing trees such as willow and birch．

　　Brazil is frequently pointed to as a nation with a major successful investment（投资）in energy coming from grains:it presently runs 330,000 automobiles on a water and alcohol（酒精）mixture,replacing 10 percent of its previous oil supply．Brazilian representatives（代表）at the conference said they wish to double this in five years,with a final goal of total replacement．Most of the cars are built at the factory to use the mixture,while older models are changed through low cost government programs．

答案：1．A;2．D;3．C;4．D;5．B;
解析：

(1)

本题为句子理解题。根据其前面的often forgotten as a promising alternative to oil即：人们过去常忘记它是一种很有前途的油的代用品，而现在received its day in the sun，由此可推知其意思是：受到大家的关注，故选A．

(2)

本题为细节判断题。根据第一段第二句可知选D．

(3)

本题为细节判断题。根据第一段最后一句可知选C．

(4)

本题为知识性判断题。从文章第一段第二句及第二段最后一句可知seaweed和willow被视为生物能；从第二段第一句及第三段第一句可知wood bark和grains被视为生物能；从文章第三段第一句可知alcohol与water的混合物被视为生物能；而oil不被视为生物能，因此crops与oil的混合物也应被视为非生物能，故选D．

(5)

本题为中心归纳题。文章虽然提到开会，但并没有介绍会议的情况，故排除选项A；文章中虽然提到过用生物能使汽车行驶，但不只是汽车，故排除选项C；文章虽然说用生物能代替石油，但并没有说，它就是缓解能源危机的关键，排除D．

　　A research team from Finland, the United States, China and Scotland is hopeful about the future of forests．Six experts in forestry science and economics say forest growth is on the increase in some countries and the number is rising．Professor Kauppi says the findings suggest the world may be able to reach a turning point away from deforestation(毁林)．Many experts have considered that impossible．But the researchers say it may be possible to expand the world’s forests by ten percent, or an area about the size of India, by 2050．

　　They used information released last year by the Food and Agriculture Organization．The new study looked at the fifty nations with the most forests．The researchers used a new way to measure forest resources．They considered more than just the amount of land covered by trees．They also considered forest density, tree sizes, biomass(生物量)and the amount of atmospheric carbon captured in forests．The biomass represents all plants and tree growth．

　　The researchers say growing stock increased in twenty-two of the fifty countries．And, in about half of the fifty countries, biomass and carbon storage also increased．The researchers say forest areas and biomass are still being lost in such important countries as Brazil and Indonesia．But they found gains in others, including the world’s most populous nations．They say China and the United States have had the greatest gains．And they say India has reached the right balance between forested and non-forested land．

　　In percentage terms, though, the study says that forest areas have expanded fastest in the last fifteen years in Vietnam, Spain and China．And they have shrunk fastest in Nigeria and the Philippines．Professor Kauppi says the main obstacle to forest growth is fast-growing poor populations that burn wood for cooking fuel, or sell it for quick money or clear forest for crops．But a number of scientists criticized the use of information that came from governments．They said some governments didn’t keep good records about their forests, and might not tell the truth．

　　The oldest and most common source(来源)of renewable energy known to man, biomass is one of the most important forms energy production in the United States and elsewhere．Since such a wide variety of biomass materials is everywhere－from trees and grasses to agricultural and city－life wastes－biomass promises to play a continuing role in providing power and heat for millions of people around the world．

　　According to the Union of Concerned Scientists(UCS), biomass is a kind of renewable energy source that produces no carbon dioxide(二氧化碳), because the energy it contains comes from the sun．When plant matter is burned, it gives off the sun's energy．In this way, biomass serves as a sort of natural battery(电池)for storing the sun's energy．As long as biomass is produced continuously－with only as much grown as is used－the “battery” lasts forever．

　　According to the Energy Information Administration, biomass has been one of the leading renewable energy sources in the United States for several years running through 2007, making up between 0.5 and 0.9 percent of the nation's total electricity supply．In 2008－although the numbers aren't all in yet－wind power probably took over first place because of the rapid development of wind farms across the country．

　　Producing power from biomass helps reduce some 11 million tons of carbon dioxide each year．Some homeowners also try to make their own heat by using biomass materials．Such practice may save homeowner's money, but it also produces a lot of pollution．So, the best way is to encourage power plants to use it．

(1)

Why is biomass considered as “ a sort of natural battery”?

[　　]

A．

It burns merely plant matter．

B．

It keeps producing electricity．

C．

It stores the energy from the sun．

D．

It produces zero carbon dioxide．

(2)

We learn from the text that in 2008 ________．

[　　]

A．

Wind power would be the leader of renewable energy．

B．

there was a rapid growth of electricity production

C．

biomass might become the main energy source

D．

0.5～0.9 of power supply came from biomass

(3)

Why does the author encourage power plants to use biomass?

[　　]

A．

To prevent the waste of energy．

B．

To increase production safety．

C．

To reduce pollution．

D．

To save money．

(4)

Where does the text probably come from?

[　　]

A．

A research plan．

B．

A science magazine

C．

A book review．

D．

A business report．
