  4-8 ADCDB4. 词义题。根据其前面的oftenforgottenasapromisingalternativetooil(人们过去常忘记它是一种很有前途的油的代用品),推及现在receiveditsdayinthesun之意为:受到大家的关注。5. 细节题。根据第一段第二句可知选D。6. 细节题。根据第一段最后一句可知选C。7. 判断题。由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;由第二段第一句及第三段第一句可知woolbark和grams被视为生物能;由第三段第一句可知alcohol与water的混合物被视为生物能;因此crops与oil的混合物也应被视为非生物能,故选D。8. 主旨题。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;文章虽说可用生物能代替石油,但并没有说,它就是缓解能源危机的关键,排除D。
