In many remote areas of the world there _________ Yeti sightings in the last three years. A have been B has been C have had D were

解题思路：见下
解题过程：
答案：A
根据in the last three years，可知需要用现在完成时，而且主语是sightings，是复数形式，所以用there have been
解题思路：
只要是there开头，后面一定要用be，构成there be 结构。
There be的一般现在时：there is/are……
There be的一般过去时：there was/were……
There be的现在完成时：there has/have been ……
There be的过去完成时：there had been ……
另外，还有there seems to be……看起来好像有……
There used to be …… 过去有……
There happened to be……碰巧有……
