问题
单项选择题
He painted his bedroom black. It looks dark and dreary. He should choose a different color.
A．had to choose
B．should have chosen
C．must have chosen
D．could have been choosing
答案
参考答案：B
解析：[分析] 词语运用 “should/ought to+ have+动词-ed形式”用来评论过去“应该做”而实际并未做的动作，含有批评的意思。本句意为：他将自己的卧室粉刷成黑色，看上去又黑暗有沉闷；他本应选一个不同的颜色。因此选项B为答案。
