语法与词汇 You’d better let me know as soon as there is a(n) _____ position in thebranch office.
【正确答案】 D
【答案解析】句意:分支机构一有空缺, 最好就尽快告诉我。 empty,hollow, vacant均为形容词, 都有“空的”的意思: empty指“里面没有东西”, 具有“空无一物”的隐含意义, 如: This trunk is empty of its contents. hollow指“空心的, 中空的, 空洞的, 下陷的”, 如: This is a hollow tree. vacant指的是“空缺的”, 如: We have no vacant position here.而vacuum是名词, 意为“真空, 空虚”。 D项最符合语境。
