The official made the demand that the soldiers at once battlefront.

A. leave; for

B. to leave; to

C. left; to

D. to be left; for

答案：

(答案→)A. leave; for

B. to leave; to

C. left; to

D. to be left; for

解析：考查虚拟语气和介词：第一空填leave，因为这是同位语从句的谓语，而同位词是demand要求的时候，同位语从句的谓语用（should） do，第二空填for，leave for动身去…，句意：官员要求士兵立刻去前线。选A。
