文章精要
本文讨论的是科学的进步与人类的发展。300年来，人类一直在从事各种科学活动，试图揭开科学的神秘面纱，构建现代文明。但是，科学发展到现在还只是个开端，人类在各方面都需要继续探索和努力，只有这样，人类才能不断提高对自然及自身的认识。
1．C细节题。由文章第一段最后一句There is an argument可知，人们对科学的看法是有争议的，选项c意思与其相反，故选C。D项干扰性大，对应第一段倒数第二句，表面上看与文章表述意思相反，但文章接下来说There is an argument，由此可知，有的人赞成倒数第二句的观点，有的人反对(即D项的观点)，故排除D。
2．D推断题。由文章第三段最后一句可知，人类对已有理论所采取的做法是修正或摈弃，所以D正确。AB对应第三段第二句，曲解了文章原意，C文中并未提及，均应排除。
3．D推断题。由文章第四段可知，30年前人们将DNA的发现称为生物革命，刚开始时，人们认为DNA细胞很简单，但随着时间的推移，人们发现它其实极为复杂，由此推断，人们还需要进一步研究，所以D正确。
4．A主旨题。由最后一段尤其是第一句中的there is everything to do可以看出，作者认为关于科学还有很多方面有待于进一步研究、探索，即科学仍处于起步阶段，前面的路还很长很长，所以A正确。
5．C观点态度题。通读全文可知，作者以客观的态度说明了科学的发展状况，并介绍了对待科学的不同观点，综合而言，作者对科学的态度是C(中立的)。A(批评的)，B(赞成的，满意的)，D(遗憾的)均不正确。
