答案没问题。我看了刘振民的书，其中时态那一章的讲述说到，during时间短语较少与现在完成时连用，而in短语却通常与现在完成时态连用。大家有没有不同意见？

during 一定跟完成时态的说法是有问题的。
我在词典上找到during 的解释：

prep.
1. 在...的整个期间
2. 在...期间的某一时候
举例：
prep.
1. Don't speak during the meal.
吃饭时别说话。
2. They met and fell in love with each other during the Second World War.
他们在第二次世界大战期间相遇并相爱。
