句义 在最近的两个小时里,我一直试图和经理取得联系,但总是占线.
表示“从过去某时开始到现在为止一直持续做某事”应当用现在完成进行时.
eg The rain has been pouring for five hours.
It has been windy for a month.
其余三个选项的时态均不符合要求.
for two hours表示一段时间
所以排除A
通过语境必然不会是过去的过去所以排除C
主要考虑B.D根据题目意思我们知道主人公一直在打电话而且带有抱怨情绪
所以用have been doing表示一直进行且带埋怨色彩
最好这样说：The answer is D. Could anyone tell me why? Thanks.
