问题 People in other parts of the world have been______(observe) Christmas for many centuries.
选项
答案 observing
解析 本题考查动词的时态。has／have been doing为现在完成进行时，表示从过去某时开始一直持续到现在的动作，并且还将持续下去。例如：It has been raining all day．It is still raining right now．(raining是在现在right now之前的一段时间里一直在持续的动作。)此句中have been observing表示从过去到现在一直过圣诞节，并且还将延续。
