Mineral water contains________, compounds needed for muscle function and energy in the human system.
选项
A、electrodes
B、electorates
C、electrolytes
D、electromagnets
答案
C
解析
本题考点是词义辨析。本句是主谓宾结构,题空处为宾语,逗号后的内容是其同位语,故理解同位语即可确定答案。同位语的大意是:(维持)人体肌肉功能和活力所需的化合物。据此对比选项:A选项electrode意为“电极”;B选项electorate意为“选民(全体),选举区”;C选项electrolyte意为“电解质,电解液”;D选项electromagnet意为“电磁体,电磁铁”。故C选项符合句意。本句大意为:矿物质水含有电解质,这些电解质是(维持)人体肌肉功能和活力所需的化合物。
