问题 Linda feels exhausted because she ______ so many visitors today.

选项 A、has been having
B、had been having
C、was having
D、had had

答案 A

解析本题考查现在完成进行时。现在完成进行时have/has been doing的用法是指动作或状态从过去某时开始，持续到现在，可能继续下去，也可能刚刚结束，而且本题主句谓语动词为一般现在时，所以从句也应该与现在时有关。如：He hasn’t been having much luck since he came here．(他自从到这儿没交多少好运。)
