Question

--- 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

Answer 1

D

試題分析：句意：凱蒂，你知道他們的班會開了多長時間嗎？當然，約四十分鐘。在賓語從句中只能使用陳述句語序，不能使用疑問句語序，結合答語中about forty minutes.可知該選D。
