2017雅思閱讀長(zhǎng)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(yǔ)breakthrough被介詞短語(yǔ)in the provision of……European Economic Community (EEC)修飾.而provision又被兩個(gè)介詞短語(yǔ)所修飾:一是在邏輯上與之構(gòu)成直接賓語(yǔ)的of energy from the sun,另一個(gè)是目的狀語(yǔ)for the European Economic Community。if引導(dǎo)的從句為主句的狀語(yǔ):according to引導(dǎo)的介詞短語(yǔ)也作狀語(yǔ)，其中過(guò)去分詞短語(yǔ)engaged in experiments in solar energy at EEC's scientific laboratories at Ispra，near Milan修飾scientists.作定語(yǔ)。
