Question

【題目】Much time _____ sitting at a desk, office workers are generally troubled by health problems.
A.being spent
B.having spent
C.spent
D.spending

Answer 1

【答案】C
【解析】句意：上班族們坐在辦工座前太久，一般會(huì)受到健康問題的困擾。分析句子結(jié)構(gòu)可知，分詞的邏輯主語和后面主句的主語不一致，應(yīng)用獨(dú)立主格結(jié)構(gòu)。分詞主語和分詞動(dòng)作之間構(gòu)成邏輯上的動(dòng)賓關(guān)系，且動(dòng)作已完成，故用過去分詞。故選C項(xiàng)。
