单元重点句型
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. 【句式解析】 a. 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）”。 b. 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。
