Question

— OK, what do you want to know?

— I’m unsure _________.

A.which is the way to the Palace Museum

B.how many colors were there in a rainbow

C.that the couple have been married for a long time

D.what he has devoted himself to improving his study

Answer

A

【解析】

句意：——好的，你想要知道什么？——我不确定哪条路是去往故宫博物馆的。

考查宾语从句。which is the way to the Palace Museum哪条路是去往故宫博物馆的，陈述语序；how many colors were there in a rainbow彩虹中有多少种颜色，疑问语序；that the couple have been married for a long time这对夫妻已经结婚很长时间了，陈述语序；what he has devoted himself to improving his study语句不通顺。根据句意，空处的句子是宾语从句，从句应使用陈述句语序，故排除B项；C项为that引导的宾语从句，意为“这对夫妻已经结婚很长时间了”和主句意思不搭配，故排除；D项中引导词what有误，宾语从句的意思不通顺，由问句what do you want to know可知，想要知道的是去往故宫博物馆的道路，故选A。
