问题 单项选择题

Mobility is one of the characteristics often ______ executives, and they must accustom themselves to moving quite regularly.

A.demanded of

B.asked for

C.expected from

D.called for

答案

参考答案:A

解析:demand of“向……要求”,demand sth. of sb. (或from sb. )“要求某人做某事”;ask for“向……要……”;ask me for the book“向我要书”;expect of“指望,期望”,不接from;call for“要求;需要”,如:This invitation does not call for an answer. 这请帖不需要答复。对于executive来说,mobility是一种要求,不是指望,这与后半句中的must呼应,所以应用demanded of。
