A解析试题分析:考查特殊句式。本题是由特殊句式:祈使句+连词+陈述句,转换而来。祈使句+连词+陈述句=If引导的条件句+主句。这个句型进一步转换成:名词短语+连词+陈述句。本题:An hour earlier,and we’ll finish the work ahead of time.=If we state an hour earlier, we’ll finish the work ahead of time.故A正确。考点:考查特殊句式。点评:本题是由特殊句式:祈使句+连词+陈述句,转换而来。祈使句+连词+陈述句=If引导的条件句+主句。这个句型进一步转换成:名词短语+连词+陈述句。
