成年人学英文的第一课和第二课刊出后,有数位读者写E-mail给我。有一位说道:「一篇文章的每一个单字都查到解释了,但整篇文章就是看不懂,怎麼办?」另一位说:「我的文法很差,没办法写完整的英文句子,要如何补救?」当发音和字汇都掌握住学习要领之后,剩下的就是「读」和「写」了,这才符合学习英文的正确步骤:听→说→读→写。台湾传统的学习方式由「写」开始,再「读」,然后才「说」,最后再去补救「听」力,可以说是背道而行,难怪效果不彰。那麼学习「读」的要诀是什麼呢?当然最重要的是能够了解整个句子的涵义。记得初中的时候背了很多文法规则,考试的分数虽然很高,但是对「读」的能力没有帮助。连那个时候流行的「英语九百句型」,也从来没有耐心读完过。然而我们今天能够看懂中文的文章,难道是因为我们熟悉中文的文法吗?答案是否定的。同样地,一个美国人虽然能阅读报纸,但是要求他做「英文文法分析」,他可能也会傻眼。英文的句子其实不需要去靠文法书中的规则去了解,文法书只应当作参考书,在有疑惑的时候才去查阅。平常应养成「约定成俗」的习惯,就是看别人怎麼用,然后「依样画葫芦」,日积月累,文法规则就化为无形了。因此,要训练「读」的技巧,不应该是靠文法规则,而是要多读。但是在读之前,要具备「了解句子」的基本能力,这就是我们的第三课─了解英文句子的要诀。了解英文句子的关键,在於先抓住「主词」和「动词」。看到一句很长的英文句子,不要害怕:先找主词,再找动词。动词如果是「及物动词」,再去找「受词」。主词、动词、受词之外,剩下的通通当做修饰语,有的修饰主词,有的修饰动词,有的修饰受词,有的修饰全句;任何两个完整的句子都可以用连接词连接起来。以上简单几句话,就是了解英文句子的基本观念。了解英文句子的第二步是熟悉英语的五种基本句型,其中前两种与不及物动词有关,后三种与及物动词有关。以下的句子中,用大括号表示{主词}或{受词},中括号表示,剩下的部份都是修饰语。第一种与不及物动词有关的基本句型叫做「简单不及物句型」(Intransitive Verb,简称I),请背住以下五个句子
