单选题
We recently received a memo ______ the Accounting Department requesting that all purchases over $1,000 be approved by the heads of sections.
【正确答案】
D
【答案解析】memo是一种公司内部流通的备忘录，横线 前有received a memo(收到一个备忘录)，横线后有部门名称the Accounting Department，故最符合句意的是表示出处的介词(D)from。receive，obtain，acquire，get，buy，purchase等动词一般和from连用。
