1. Franklin, alng with many ther scientists, has inspired us and taught us that scientific experiments are imprtant in rder t establish the truth and t cntribute [句式分析] 结构“Franklin, alng with many ther scientists”作主语时，谓语的人称与数要与“with前面的部分”保持一致, “ in rder t d sth” 意为“为了...”, 引导“目的状语”, “ and t cntribute” 构成并列性目的状语。 [尝试翻译] 富兰克林和许多其他科学家一起启发并教导我们，为了确认真相并有助于后来的科学发现与发明，科学实验是很重要的。

2. Mre than ne accunt suggests that while Newtn was certainly inspired by a falling apple, there is n prf that it hit him n the head. [句式分析] Mre than ne+单数名词，意为“不止一个...”, 作主语时，谓语用“第三人称单数形式”； 句中“suggest”意为“表明”，引导宾语从句时，从句的谓语用“陈述语气”， 注意suggest表示“建议”引导从句的谓语用“虚拟语气（shuld +verb）”。 名词 “prf”后接that-clause为“同位语从句”——同位语从句,指的是在复合句中充当同位语的从句，属于名词性从句的范畴，同位语从句用来对其前面的抽象名词进行解释说明，被解释说明的词和同位语在逻辑上是主表关系。 [尝试翻译] 不止一种说法表明，虽然牛顿肯定是受到了一个掉落的苹果的启发，但没有证据表明它击中了他的头部。
