--- Kitty, do you know ______?
---Sure, about forty minutes.

A．when did their class meeting begin.

B．where their class meeting was held

C．how often their class meeting is held

D．how long their class meeting will last

答案

D

解析

试题分析：句意：凯蒂，你知道他们的班会开了多长时间吗？当然，约四十分钟。在宾语从句中只能使用陈述句语序，不能使用疑问句语序，结合答语中about forty minutes.可知该选D。
