What does the underlined sentence “But finally it’s greatly liberating” mean?
A、It is of great use.
B、It can set people free.
C、It is difficult.
D、It is troublesome.
【正确答案】:B
【题目解析】:句意理解题。本句实际上是考查难词liberate的含义,该词意为“解放,给予自由”,同时根据文章的大意:对别人说“不”你能节省大量的时间,可知通过拒绝别人你能享有更多自由,由此可知该题答案为B。A的说法过于笼统,C和D都是消极含义,都是错误的。
