The house is dirty because it since they moved out.

A．doesn’t clean

B．isn’t cleaned

C．hasn’t cleaned

D．hasn’t been cleaned

答案

解析

试题分析：考查时态：句意：房子很脏，因为自从他们搬出去了一直没有被打扫。时间状语是since连接的时间状语从句，和现在完成时连用，因为the house和clean是被动关系，用现在完成时的被动。选D。
点评：英语中的时态主要由动词的形式决定，因此在学习英语时态时，要注意分析动词形式及具体语境，想象在那个特定的时间动作所发生的背景，这个动作是经常性动作、一般性动作、进行性动作、完成性动作还是将要发生的动作。这题的关键是since连接的时间状语从句。
