拇指英语说，分享英语学习心得，技巧和方法。让英语学习变得更有趣，更简单。

在英语学习中，词汇量的大小是衡量英语水平的重要标志。通常词汇量越大，运用英语的能力就越强，反之亦然。许多英语偏弱的学生将词汇的学习与记忆比作“拦路虎”，以至谈虎色变，毫无信心。因此，有意识地学习词汇策略将可以帮助学生更科学，高效，简单地积累大量词汇，从而达到事半功倍的效果。本词汇积累策略系列，将会从近义词(synonyms)，反义词(antonyms)，前缀(prefixes)，后缀(suffixes)，同音异义词(homophones)等角度来探讨词汇的学习和积累。本系列，适合小学中高年级及初中学生学习。

The Root Word plic: 词根 graph/ graphy

词根graph，这个词根来自希腊语，本意就是“刻”，在某个东西的表面上留下刻痕。古人没有笔，都是通过刻的方式来记录信息，所以这个词根又引申为写，画。它既是个动词词根，又是个名词词根，表示文字、图画，写下的东西。

比如单词autograph，前面的auto表示“自己，亲自”，后面的graph表示写。合起来就是亲自去写，特指亲自去写自己的名字也就是亲笔签名。

词根graphy也可以表示写，或者表示对某一主题的研究。以上这二个词根都可以和不少的前缀及后缀组合成新的单词。

下面我们首先来看看下面方框中的词干。请大家在这些词干后加上词根graph 或者graphy来构成新的单词。然后将这些单词和下面的英语解释配对。
