1. 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 a 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.

【译文】根据欧洲经济共同体资深科学家在伊斯普拉(米兰附近)实验室所进行的实验表明，如果欧共体在太阳能供应这一领域的研究工作有些许增加，就能提前二十年取得该领域的突破。
【析句】多重复合句，主句为A breakthrough could be brought forward by two decades,could此处表示一种可能性，从句为if引导的条件状语从句，最后是according to引导表示参考的状语the senior EEC scientist,engaged in experiments为过去分词作定语。
