As a senior high student, you should 　　 your energy on how to master the skills of learning. A．impress B．spend C．concentrate D．use

Answer 1

C

试题分析：词的用法。Concentrate ...on ,集中...于spend time/money on sth/in doing sth 花时间/金钱做某事. Impress 给...印象句意：作为一个高中生，你应该把你的精力集中在怎样掌握学习的技能上。故选C 点评：注意与介词的搭配。补充：fix/focus/concentrate....on, attract/catch one’s attention to
