单项选择题
关于具体行政行为的效力，下列哪一选项说法是正确的
A．具体行政行为的拘束力一经生效即产生
B．具体行政行为的确定力指具体行政行为一经生效，当事人即应当遵守
C．具体行政行为的执行力在争议期经过后才能产生
D．具体行政行为的拘束力、确定力和执行力是冲突的，不能并存的
答案
参考答案：A
解析：[考点] 具体行政行为的效力 具体行政行为有三种效力，即拘束力、确定力和执行力。拘束力实际上是一种法律推定的效力。具体行政行为一旦生效拘束力就随之产生，无论是行政主体、行政相对人，还是其他的机关、组织和个人，均应遵守，故A项正确。确定力在争议期过后产生，就是一种最终确定的效力。它指的是具体行政行为在法律上最终地、实质地被确定下来，从而不再更改的效力，B项错在确定力产生时间上。执行力在履行期过后产生，C项不正确。具体行政行为在履行期过后，其拘束力、确定力和执行力即是并存的，D项不正确。
m deeply influenced by her. About two years ago, I borrowed a video called “Speed,” in which Sandra played a role. At that time, I still didn’t know who she was. But after seeing that great movie, I was totally struck! Her performance and smile really attracted me. At that time, I started collecting everything about Sandra from magazines, TV and newspapers. But unfortunately, I couldn’t find much information in my hometown. That really disappointed me. All I could do was to get on the internet. Luckily, there were many foreign web sites. I was really happy then. But there was a big problem for me: the Web sites are all in English. So, English became an important part in my life. I decided to learn English well and to be able to read and understand everything. The craziest thing I’ve ever done was to record all her movies, film previews（预告）and interviews. I listened to them over and over every day. When I heard any word that I didn’t understand, I would look them up in the dictionary. That was a good for me because I could learn them in a very short time. It does work, and I never get tired of doing this. It’s been two years since then, and my listening and reading abilities are better than before. I can even chat with my foreign friends on the internet. I should say from the bottom of my heart, “Thank you so much, Sandra.”
