鲁云平回答：

　　1.A2.C3.C4.A 　　分析：　　人的寿命和什么有关呢？波士顿大学的ThomasPerls博士指出除了人的居住环境、健康低脂、低碳的饮食，积极的心态和有规律的锻炼外，人的基因也在人的寿命中起着重要作用。而且一个人越长寿，他的基因就起的作用就越大。1.A细节理解题。从文章首段butexceptional(特别的)longlifemayhaveevenmoretodowithyourgenes.可知大多数人的寿命和基因有关，所以A选项正确。2.C细节理解题。根据文章第三段Hispreviousworkhasshownthatamongmostelderlypeoplewholiveintotheir70sand80sabout70%canowetheirlonglifetoenvironmentalfactors判断Perl认为百分之七十到八十的人长寿和环境因素有关，所以C选项正确。3.C细节理解题。根据文章第三段中的heisthefirsttoacknowledgethatlivinglongerisn’tlikelytobesimplyamatterofgenes.可知C选项内容错误。4.A主旨大意题。作者在文章首段提出研究人员发现基因谱能准确预测哪些人能够长寿，然后就此展开详细叙述，由此可知最佳题目应该是GenesMayPredictWhoLivesto100，故A选项正确。　　考点：　　考查科学知识类短文阅读。
