　　分析：

　　本文讲述的是科学家在研究人类是否能够活得更长更健康，以及不同的人对此问题的不同的反应。1.C推理题。根据本句weareknockingatthedoorofimmortality(永生)指我们敲响了永生的门，说明我们已经了解到了一些关于永生的秘密，结合第一段内容可知C正确。2.D细节题。根据第二段最后3行“Thereisagreatpushsothatpeoplecanlivefrom120to180years”hesaid.“Somehavesuggestedthatthereisnolimitandthatpeoplecouldliveto200or300or500years说明他认为人类永生是有可能的，故D正确。3.B推理题。这里的it就是指上一段里的“Thereisagreatpushsothatpeoplecanlivefrom120to180years”hesaid.“Somehavesuggestedthatthereisnolimitandthatpeoplecouldliveto200or300or500years.活的时间超过现在的预测。故B正确。4.A主旨大意题。本文讨论的主要就是人类在未来是否可以活的更久一点，故A项正确。

　　考点：

　　考查科普类短文阅读

　　点评：

　　对于人类是否可以活得更为久远，文章中给出了答案。属于科普类的短文，此类文章的最大的障碍是词汇以及考生对阅读内容的不熟悉，需要考生在阅读的时候有足够的耐心。要养成在上下文串联中猜测词义的能力，根据上下文中出现的同义词，近义词，反义词，以及词义的解释来理解生词。同时要抓住文章的中心，不要受其他信息的影响。要根据题目及选项以及文章的上下文串联合理的判断推理。
