问题补充：

anything, give me a call and Ill be glad to help you.

A. Had you required

B. Should you require

C. Would you require

D. Could you require

答案：

A. Had you required

(答案→)B. Should you require

C. Would you require

D. Could you require

解析：考查虚拟语气和倒装。句意：如果你有什么要求，给我打个电话，我将乐意帮助你。根据句意可知此处是对将来的虚拟，前半句是“If you should require anything”的省略形式，省略if后，需要将should提到主语前，此处should表示“假如；万一”。选B。
