正确答案: C

社会主义制度的自我完善和发展

题目：我国社会主义改革是一场新的革命，其性质是 （ ）

解析：

 本题考查的知识点是我国社会主义改革的性质。我国社会主义改革的性质是社会主义制度的自我完善和发展。因为改革是在中国共产党的领导下进行的，它丝毫没有改变社会主义的根本制度。所以选项B错误。邓小平指出，在改革中我们必须始终坚持的根本原则是坚持公有制经济的主体地位，坚持共同富裕。这就确保了改革的性质不会改变。通过这种改革，社会主义制度会得到进一步巩固和完善。选项A是社会主义的根本任务。选项D是我国经济体制改革的目标。因此，正确答案选C。

解析：[答案] A

[单选题]Ethosuzimide, which was developed in the 1950s, is commonly used to treat epilepsy, though it is no known precisely how the drug controls convulsions. There is no anecdotal evidence that it has had an anti-aglng effect in people. The next step, Komfeld says, is to test if the drugs have an anti-aging effect on animal like flies and mice。 Very little is known about the aging process. From genetic analysis, researchers have found that an in sulin-like signaling system regulates aging and longevity. A good diet can delay aging and extend a person life span. But scientists know virtually nothing about the effect of drugs on aging. “It’s a big void, ” Konfeld said。 In addition to delaying age-related degenerative changes, the drugs also increased neuromuscular activty, suggesting a link between the neuromuscular system and the aging process。

But Komfeld said scientists will not know about the applicability of the drugs in humans until a similar study is done on humans. “What’s very encouraging is that these drugs were developed to treat humans, and they are well understood, because they’ve been used for a long time, ” he said。

解析：空前文字提到：“有理由相信这种实验结论对更高级的动物，如人类，也同样适用”。所以这一空应该继续谈到实验结果对人类究竟是不是适用的问题。选项A提到：“但是科学家们目前还不知道究竟对人类是不是适用，除非也在人类身上做相同的实验”。显然，选项A最合适。
