问题
选择题
______ to improve our environment?
A．What do you think we should do
B．Do you think what we should do
C．What do you think should we do
D．Do you think what should we do
答案
答案：A
题目分析：句意为：为改善环境你认为我们该做些什么？当主句是Do you think这种一般疑问句时候，一般都把do you think放于宾语从句的引导词后，此时do you think是句子的插入语，后面的句子要改为陈述句，所以是we should do，故选A。
