2017雅思閱讀長難句例句分析（4）

　　題目：

　　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：

　　全句主干為:“A breakthrough... could be brought for ward……;主語breakthrough被介詞短語in the provision of……European Economic Community (EEC)修飾.而provision又被兩個(gè)介詞短語所修飾:一是在邏輯上與之構(gòu)成直接賓語的of energy from the sun,另一個(gè)是目的狀語for the European Economic Community。if引導(dǎo)的從句為主句的狀語:according to引導(dǎo)的介詞短語也作狀語，其中過去分詞短語engaged in experiments in solar energy at EEC's scientific laboratories at Ispra，near Milan修飾scientists.作定語。
