Question

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 (投資)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.
4. In Line 2, the phrase received its day in the sun most probably means ________.
A. came to the public mind                    B. had its turn in the sunlight
C. was regarded as a solar energy                  D. came from the energy of the sun
5. Which of the following statements is supported by the passage?
A. 1, 700 scientists attended the conference.
B. A quarter of American businessmen were present at the conference.
C. Foreign policy-makers accounted for a quarter.
D. Three-quarters of the representatives were from the U. S.
6. Of the total supply in 2010, biomass in the U. S. will be________.
A. 5%              B.20%              C.10%              D.15%
7. Which of the following is not regarded as biomass energy?
A. Willow and seaweed.                     B. Wood and grains.
C. Water and alcohol mixture.              D. Crops and oil mixture.
8. A suitable title for this passage would be ________.
A. An Energy Conference                    B. Approval of Biomass Energy
C. Bio-Energy for Automobiles       D. Keys to Energy Crisis

4.   詞義題。根據(jù)其前面的often forgotten as a promising alternative to oil (人們過去常忘記它是一種很有前途的油的代用品)，推及現(xiàn)在received its day in the sun之意為：受到大家的關(guān)注。
5.   細(xì)節(jié)題。根據(jù)第一段第二句可知選D。
6.   細(xì)節(jié)題。根據(jù)第一段最后一句可知選C。
7.   判斷題。由第一段第二句及第二段最后一句可知seaweed和willow被視為生物能；由第二段第一句及第三段第一句可知wool bark和grams被視為生物能；由第三段第一句可知alcohol與water的混合物被視為生物能；因此crops與oil的混合物也應(yīng)被視為非生物能，故選D。
8.  主旨題。文章雖然提到開會(huì)，但并沒有介紹會(huì)議的情況，故排除選項(xiàng)A；文章中雖然提到過用生物能使汽車行駛，但不只是汽車，故排除選項(xiàng)C；文章雖說可用生物能代替石油，但并沒有說，它就是緩解能源危機(jī)的關(guān)鍵，排除D。
