最后一个it 直接把我，撂倒了，不知道指代啥 感觉but后的句子好乱，求指点作者: slgbond 时间: 2012-9-27 19:09
顶起来，有没有好心人答复啊。。作者: nancy716 时间: 2012-9-27 20:50
it 指代this statement,也就是至题目的B选项,第二个it指代converting the Hevelia airstrip to a full-service airpot，意思就是 B选项这个陈述表明一个靠近G机场的未经开发的跑道可能是缓解G机场飞机延误的更好的办法（与在40英里外修建Hevelia跑道相比），但是这个陈述没有告诉我们任何把H跑道转变成全方位服务的机场后的结果.我觉得but后面的句子可能是but it tells us nothing about the effects that converting the Hevelia airstrip to a full-survice airport would have if it were carried out.作者: slgbond 时间: 2012-9-27 21:29

were it to be carried out是 if it were to be carried out 的倒装 是个虚拟语气； were to是 is to的过去时，虚拟语气中is am 的过去时都用were
