2）句中的副词even修饰比较级taller, 它没有实际意义，只起加强语气的作用。可用来修饰形容词或副词比较级的词或短语还有much, far, still, rather, a lot, a great, deal, a little, a bit等。例如：
It’s a bit cold today. 今天有点冷。
His book is far more interesting. 他的书更加有趣。
so that he can catch the first bus.
in order that he can catch the first bus.
so as to catch the first bus.
in order to catch the first bus.
to catch the first bus.
本单元重点的语法项目是表示目的的方式，下面将表示目的的几种方式归纳如下。
1、动词不定式（包括 so as to，in order to）。
2、用so that和 in order that引导目的状语从句，从“句中一般含有情态动词can，could，may，might等。下面以“为了能赶上第一班车，他每天都起得很早”为例。
He gets up early every morning
以上是用肯定句结构。
用否定结构，注意“不定式的否定结构在to前加not; so that/ in order that 只有在主句主语和从句主语一致的情况下可以换成 so as to／in order to；in order to可放于句首，so as to则不可）
so that he can’t miss the first bus.
in order that he cant miss the first bus.
so as not to miss the first bus.
in older not to miss the first bus.
so that也可用来引导结果状语从句。在so that引导的结果状语从句中，谓语动词前不用情态动词，主从句间可有逗号隔开。例如：
Everyone said no, so that the plan was dropped. 大家都反对，计划就不再讨论了。
