試題分析：考查if條件句的省略倒裝：句意：如果他沒(méi)有酒后駕駛，就不會(huì)出事了。因?yàn)槭呛瓦^(guò)去相反的虛擬條件句，用if he had not driven…，當(dāng)虛擬條件句的謂語(yǔ)部分含有were, should, had時(shí)，我們可以將連詞if省略掉，而將were, should, had置于句首。這里的Had he not driven ="if" he had not driven…，是和過(guò)去相反的虛擬語(yǔ)氣條件句，選A。
考點(diǎn)：考查虛擬語(yǔ)氣的省略倒裝
點(diǎn)評(píng)：當(dāng)虛擬條件句的謂語(yǔ)部分含有were, should, had時(shí)，我們可以將連詞if省略掉，而將were, should, had置于句首。注意：對(duì)于條件從句含有should而主句使用陳述語(yǔ)氣或祈使語(yǔ)氣的句子也可以采用以上方法進(jìn)行省略和倒裝。如果條件從句為否定式，注意要將not置于主語(yǔ)之后，而不置于主語(yǔ)之前。
