问题补充:

A. how much it costs
B. how soon it takes
C. how long I will take
D. how many hours I will spend
答案:
A. how much it costs
B. how soon it takes
C. how long I will take
(答案→)D. how many hours I will spend
解析:句意:--你能告诉我我要花几个小时到大连吗?--坐飞机大约两个小时。cost、take、spend都有花费时间或金钱做某事的意思,但用法有区别:cost 物作主语;take通常由形式主语it做主语;spend 人做主语,spend---(in) doing sth。空格后为traveling,故选D。
