【題目】Backward somewhat technologically ________ we are for the moment, we have confidence in our ability to catch up in time.

A. although B. if C. as D. once

【答案】C

【解析】考查連詞。A. although盡管；B. if如果；C. as雖然；D. once一旦。句意：雖然我們技術(shù)上暫時(shí)有點(diǎn)落后，但我們有信心有能力及時(shí)趕上。此處表示讓步，意義上A、C都可以，但although不用于倒裝句，as用于讓步狀語從句只能用于倒裝句，故選C。
