长难句训练:Most Southern Airways flights, but not its flight from Pederton to Dacenta, use Sarmouth airport, which because of its mountainous location is one of the world's most dangerous.its指代单数,那不能指代南航的flights,它是复数;its mountainous location 说明指的是机场而不是航线从P到D,所以its只能指代Sarmouth airport。
大部分南航航线都要使用Sarmouth airport,那是全世界最危险的机场-->南航事故率高并不是因为驾驶技术不好二是因为Sarmouth airport的关系;现在P到D的航线不用这个机场了,自然是安全的航线,用不着多花钱坐D家的飞机。
D,只在过去的几年里,从P到D的航班才D家的比南航的贵,意思是再远几年,两家的票价是一样的;同时也不能说明D的更贵的票价没有被用到增加航班安全上。属于无关选项。
