He felt very sad that though he worked veryindeed,he was not able to jump.

A. hardly; high

B. hard; high

C. hardly; highly

D. hard; highly

答案：

A. hardly; high

(答案→)B. hard; high

C. hardly; highly

D. hard; highly

解析：句意：他感到很难过，虽然他很努力，他还是不能跳的很高。第一空填hard副词“努力”，hardly“几乎不”，第二空填high副词“高地”表示具体的概念，highly“高地”，表示的是抽象的概念，选B。
