中 * * 党从1921午成立到1949年领导人民取得了新民主主义革命的伟大胜利，但是在1927年实际上就已经在井岗山上建立了革命根据地，一部分人民已经率先获得了解放。那么1927年在解放区实现的是 ( )
A．爆发式飞跃
B．阶段性部分质变
C．局部性部分质变
D．非爆发式飞跃
参考答案：C
解析：[注释] 部分质变有两种形式：局部性部分质变和阶段性部分质变，前者是指全局的性质未变，而局部的性质首先发生了质变，是在空间的意义上而言的；而后者则是指根本性质未变，而非根本性质首先发生了质变，是在性质或发展阶段的意义上而言的。爆发式飞跃和非爆发式飞跃则是指根本质变的两种基本形式。中国革命的根本质变一直到1949年10月1日才真正发生，在此以前都是总的量变过程，发生的质变都是部分质变。因此，正确选项为C。
阅读下面短文，并根据所读内容在表格中的空格处填入恰当的单词。 注意：每个空格只填一个单词。 “HEARTLESS”— a word you wouldn’t want to use to describe a person. But having his heart removed was what saved Craig Lewis’ life—and what made him the first living “heartless” man. The 55-year-old，dying of heart disease，was told he only had 12 hours to live， when Billy Cohn and Bud Frazier, doctors from the Texas Heart Institute, decided to try something new. They removed Lewis heart and replaced it with an artificial (人造的) one. Less than a week after the operation, Lewis was able to sit and speak. Lewis kept on living like a normal person, with only one difference—he didn’t have a heartbeat. The human heart usually pumps blood through our bodies by beating regularly. By contrast, this artificial heart pushes the blood forward with two moving blades(桨叶). If you were to touch Lewis or listen to his chest, you would not feel a heartbeat. If you hooked him up to an EKG(心电图) machine, the line would be flat. Scientists have been trying to create a working artificial heart for years. Until now, all artificial hearts either broke down or caused blocks and infections. But after five years of hard work, Dr Cohn and Dr Frazier developed this artificial heart. It is smaller and quieter than other artificial hearts and can last much longer. They tested it on 38 calves (牛犊) and all of them turned out energetic and healthy. Lewis is the first human proof that the machine is a success. The doctors will have to work more on the device and decide on a final design before it can be widely used. The US Food and Drug Administration will also need to say that the machine is safe. But this artificial heart looks likely to bring a ray of hope to thousands of patients.
