单项选择题
—We've spent too much money recently.
—Well, it isn't surprising. Our friends and relatives()around all the time.
A. are coming
B. had come
C. were coming
D. have been coming
答案
参考答案：D
解析：
本题考查动词的时态。上句意思是：我们最近已经花掉很多钱了。下句意思是：不奇怪，我们的朋友和亲戚这段时间总来我们家。由all the time可知应该用进行时，表示持续的动作，故排除B。由句意可知这是过去到现在一段时间发生的动作，动作影响还在持续，所以应该用现在完成进行时。故选D。
