题目

The journey around the world took the old sailor nine months,__the sailing time was 226 days.
A of which B during which C from which D for which
为什么不可以用B?在这9个月的期间,有226天航行时间……选A 和B 的区别

答案

定语从句
of which 就是指“九个月的航行时间”即：the sailing time of nine months
during which 就是指“在九个月期间”这与后面“航行时间”没有任何逻辑关系,故不可以用.
