英语单词前缀用法（玩转英语词汇--）

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 Prefix ad-: 前缀 ad-

前缀ad- 意思有达，到(＝ to; towards)；根据(＝ up to; according to)。ad加在在单词或词根前，还表示”做…，加强…”。比如adapt适应（ad apt能力→有适应能力）、adept熟练的（ad ept能力→有做事能力→熟练的）、adopt收养；采纳（ad opt选择→选出来→采纳）、adhere坚持（ad here粘→粘在一起→坚持）、adjacent邻近的（ad jacent躺→躺在一起→邻近的），等等。
