We began to open to the outside world in the late 1970s.    ,there have been great changes in the country.

A．As a result of

B．As a result

C．First of all

D．After all

答案

B

解析

试题分析：考查固定词组，As a result of意思“……的结果”，As a result意思“结果”，First of all意思“首先”，After all意思“究竟”，句子意思“在上个世纪70年代末，我们开始对外开放，结果，我们国发生了很大的变化”，所以选B
点评：固定词组open to the outside world意思“对外开放”， in the late 1970s意思“上个世纪70年代末”，固定句型begin to do sth意思“开始做某事”，固定词组要靠平时多记多积累。
