1、so... that...句型中的so是副词,常常用来修饰形容词或副词,意思是“如此/这么…以致于…” 常用句型为:①主语+谓语+so+adj. / adv. + that从句。 如:The boy ran so fast that I couldn't catch him.
②so+形容仿弊词+a(n)+单数名词+that从句。如: She made so good a meal that we all ate far too much.
2、形容游唯词最高级前通常要加定冠词神大培the,而当形容词最高级前有序数词、物主代词、指示代词或名词所有格等限定词修饰时,最高级前不用the。这里second就属于序数词了,所以不加定冠词the。
