2017雅思阅读长难句例句分析（4）

　　题目：

　　A breakthrough in the provision of energy from the sun for the European Economic Community (EEC) could be brought forward by up to two decades, if an modest increase could be provided in the EEC's research effort in this field, according to the senior EEC scientists engaged in experiments in solar energy at EEC's scientific laboratories at Ispra ，near Milan.

　　 分析：

　　全句主干为:“A breakthrough... could be brought for ward……;主语breakthrough被介词短语in the provision of……European Economic Community (EEC)修饰.而provision又被两个介词短语所修饰:一是在逻辑上与之构成直接宾语的of energy from the sun,另一个是目的状语for the European Economic Community。if引导的从句为主句的状语:according to引导的介词短语也作状语，其中过去分词短语engaged in experiments in solar energy at EEC's scientific laboratories at Ispra，near Milan修饰scientists.作定语。
