问题 China’s economic reform is aimed at separating enterprises from the government. It has been implemented for almost 20 years, but breakthroughs______.

选项 A、have been made yet
B、have yet to make
C、have yet to be made
D、to have yet made

答案C

解析本题可用排除法。根据空格处的意思“尚未取得突破”可知A选项不正确，就排除了A。因为句子主语是“breakthroughs”，所以要被动语态，B、D选项也被排除。因此正确答案为C。
