【題目】Scientists think calculating is a necessary skill_________ they base their researches.

A. on it B. on that

C. on which D. on whose

【答案】C

【解析】考查定語(yǔ)從句。句意：科學(xué)家認(rèn)為計(jì)算是一種依據(jù)他們的研究為基礎(chǔ)的必須技能。 base on....意為“依據(jù)......為基礎(chǔ)”。a necessary skill做先行詞，指物，在后面的定語(yǔ)從句中做on的賓語(yǔ)，故選C。
