- Year. well, I--- all night preparing for my history exam. I can hardly keep my eyes open.
A stayed up B have stayed up C have been stayed up D will stay up选什么为什么

【stay up】熬夜

甲： 又喝了一杯咖啡？ 这已经是你午饭后的第三杯了！
乙： 是呀，我（昨晚）整夜没睡准备历史考试。我现在眼睛都睁不开了。

【答案】A 根据情景（对话发生在下午、乙昨夜熬夜、现在熬夜已经停止）选择过去式

will stay up..
他将整夜不睡觉准备历史考试.所以需要喝咖啡
stayed up, have stayed up, have been stayed up 都是过去,而这里的情况时还没发生的.应该用will
