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 have／has been doing的用法是指过去的动作或状态从过去某时开始，持续到现在，可能持续下去，也可能刚刚结束，多用于可延续性动作.本题主句用的是一般现在时，所以从句也应该与现在时有关。如：Hehash’t been having much luck since he came here．(自从来到这里他就不太走运。)故A项为正确答案。
