[A] stable [F] marvelous [K] comprise
[B] solutions [G] included [L] competitions
[C] significant [H] growth [M] combined
[D] role [I] exactly [N] challenges
[E] progress [J] consist [O] certainly [br] 【S9】
选项
答案
K
解析
分析空所在的句子结构可知,本句缺少谓语,由该句的主语important...sources以及前后文的一般现在时态可知,本空应填一原形动词,[E]、[J]和[K]入选。由后面提到的“当今市场的1%”可知,此处应该是说重要的替代能源在市场所占的份额,故答案为[K]comprise“组成,构成”,常用来表示部分构成整体,主语为部分。[J] consist“包含,包括”常用来表示整体包含部分,主语为整体。
