单选题 Please be informed that all telephone calls ______ in our database for quality assurance and employee training purposes.
A. will record
B. will be recording
C. will have recorded
D. will be recorded

【正确答案】 D
【答案解析】这道题考查的是动词变形。因为每一个备选答案中都有“will”,所以没有必要纠结于时态。再看空格前面,主语是“all telephone calls”,即主语是“物”。我们应该知道,如果主语是“物”,后面的动词一般都用“被动语态”,因此可以得出“all telephone callsare recorded”。接下来,我们只要把它变成将来时,就能得出这句话的正确说法,即“alltelephone calls will be recorded”,所以答案是(D)。
