【題目】China ________ (change) a lot in the past 40 years and now it is playing an important role on the world stage.

【答案】has changed

【解析】

句意:中國在過去的40年里發(fā)生了很大的變化,現(xiàn)在它正在世界舞臺上發(fā)揮著重要的作用。

根據(jù)in the past 40 years,可知句子時態(tài)用現(xiàn)在完成時,其結(jié)構(gòu)為has/have+動詞的過去分詞;主語是China,第三人稱單數(shù),助動詞用has,change的過去分詞是changed;故答案為has changed。
