19考研英語：屠屠長難句（二十九）

1、每日一句長難句（29）

The goal of all will be to try to explain to a confused and often unenlightened citizenry that there are not two equally valid scientific theories for the origin and evolution of universe and life.

2、【分析】

該句的主幹是The goal … will be to try to explain...，explain後接的是雙賓語，即explain to sb. sth.，直接賓語是that引導的從句。該從句的主幹是there are not two theories for...，其中origin和evolution，universe和life都是and連接的並列名詞。

3、【詞彙】

unenlightened adj. 無知的，不文明的

valid adj.有效的

evolution n. 進化，發展

4、【譯文】
