问题补充：

—What time is it? — It’s（7：45）

A. six thirty

B. forty-five past seven

C. a quarter to eight

D. a quarter past seven

答案：

A. six thirty

B. forty-five past seven

(答案→)C. a quarter to eight

D. a quarter past seven

解析：句意：——几点了？——差一刻到八点。 A .six thirty 六点半； B. forty-five past seven 表达错误，正确的说法应是seven forty-five；C. a quarter to eight 差一刻到八点； D. a quarter past seven七点过一刻。在英语中大于三十分钟时用介词to;小于三十分钟时用介词past;此处7：45，故用介词to，表示差一刻钟到八点。故选C。
