A．As a result of

B．As a result

C．First of all

D．After all

Answer 1

B

試題分析：考查固定詞組，As a result of意思“……的結(jié)果”，As a result意思“結(jié)果”，F(xiàn)irst of all意思“首先”，After all意思“究竟”，句子意思“在上個(gè)世紀(jì)70年代末，我們開(kāi)始對(duì)外開(kāi)放，結(jié)果，我們國(guó)發(fā)生了很大的變化”，所以選B
點(diǎn)評(píng)：固定詞組open to the outside world意思“對(duì)外開(kāi)放”， in the late 1970s意思“上個(gè)世紀(jì)70年代末”，固定句型begin to do sth意思“開(kāi)始做某事”，固定詞組要靠平時(shí)多記多積累。
