我的理解有一个地方和陈老师的解答不同， 我认为over the past year 应该是后置定语修饰efforts. 其它赞同陈老师的解答。

Officials familiar with the calls say (that 省略)the efforts have not been a departure from the administration’s efforts over the past year to push oil producers to keep production levels high after Russia’s invasion of Ukraine, which has roiled global markets

解答如下：供网友参考

【1】over the past year 为介词短语作时间状语，修饰不定式短语 to push oil producer....

【2】to push oil producers...为不定式短语修饰前面名词efforts

【3】after Russian's invasion of Ukraine为介词短语作时间状语，修饰不定式短语to push oil producer...

备注(1):over the past year(在过去1年时间里)为总的大时间范围，after Russian's invasion of Ukraine(在俄罗斯入侵乌克兰之后)属于大时间范围里的小时间范围，这2个时间状语都是用来修饰不定式短语to push oil producers to keep production levels high(推动石油生产商保持高产量水平)

【不定式短语 to keep production level high为不定式宾语oil producers的宾语补足语，即push sb/sth to do sth 推动/督促某人/某物做某事.】

备注(2):over the past year to push oil producers to keep production levels high after Russia’s invasion of Ukraine(过去一年里在俄罗斯入侵乌克兰后推动石油生产商保持产量高位的)整个不定式短语修饰前面名词efforts(努力)。
