science moves forward,they say,not so much through the insights of great men of gennius as because of more ordinary things like improved techniques and tools.

參考答案:

要點(diǎn)：本句中not so much through the insights of great men of gennius as連接狀語，意思是“與其說...不如說...”。they say可以放在句首，放在句首是主謂結(jié)構(gòu)，放在此處是插入語，造成句子的，翻譯時(shí)按主謂結(jié)構(gòu)譯出。

譯文：他們說，科學(xué)的發(fā)展與其說源于天才偉人的真知灼見，不如說源于改進(jìn)了的技術(shù)和工具等更為普遍的東西。
