試題分析：考查虛擬語氣：if條件句用had done表示和過去的事實相反，主句用would have done表示虛擬，句意：如果沒有青霉素，很多人就會死于疾病或小的傷口。選B。
考點：考查虛擬語氣
點評：虛擬語氣在條件句中的用法是：虛擬條件句 與現(xiàn)在事實相反的假設，從句是If+主語+動詞的過去式（動詞be用were)，主句是：主語+should,would, might,could＋動詞原形；與過去相反的假設從句用：If+主語+had +過去分詞，主句是：主語＋should, would, might, could ＋have done；與將來相反的假設，從句用1、If+主語+動詞過去式，主語＋should, would  do，2、If+主語+were to+ 動詞原形，加主句3、If+主語+should +動詞原形 ，加上主句的might, could＋動詞 原形
