解答：

她每两天服用半片，所以一片药可用 $4$ 天。 $60$ 片药可用 $60 \times 4 = 240$ 天。

按每月约 $30$ 天计算，约为 $240 \div 30 = 8$ 个月。

所以正确答案是 D。

She takes half a pill every two days, so one pill lasts $4$ days. Then $60$ pills last $60 \times 4 = 240$ days.

At about $30$ days per month, that is roughly $240 \div 30 = 8$ months.

Thus, the correct answer is D .
