　　1.A 推理題，答題依據(jù)在本文第2段前半部分。這一部分提到，我們對自然界所知甚少，作者認為這是過去一百年以來生物學(xué)的重大發(fā)現(xiàn)。從這一方面講，這是一個具有啟發(fā)意義的消息。如果18世紀最聰明的啟蒙運動者被告知我們現(xiàn)在是多么無知，多么對人類的未來感到茫然，他一定會驚訝不已。由此可以推斷，他們當時自認為所知很多，能夠解決大部分的科學(xué)問題。

　　2.B 推理題，答題依據(jù)在本文第1句：科學(xué)的前景如何?這個問題實難預(yù)測。如果是真正的科學(xué)，就不能進行預(yù)測。

　　3.C 設(shè)題區(qū)在第2段后半部分。A、B、D項在該部分都有涉及，只有C項沒有提到。

　　4.A 推理題，依據(jù)見末段第2句：只要是人們能想到的問題，遲早都會得到解答。B項的意思是，由于人的智力有限，他并非能解決他能夠想到的所有問題，這與原文意思不符。

　　5.C 作者對科學(xué)所持的態(tài)度可以從本文最后兩句看出來：雖然他意識到科學(xué)面臨著巨大的困難，但還是很有信心。
