定义英语的单词不断发展、不断增加，新词的构成要服从一定的语法规则，遵循一定的规律。语言学家把这种专门研究词形变化现象和规则的学问称为词形学（Morphology），通常简称为构词法（WordFormation）。

三种主要构词方法转化（Conversion）：不借助构词词缀，把一个单词从一种词类转化成另一种词类。由于词类转化的结构，英语中就形成了大量外形相同但词类不同的词，即同形异类词。例如：filmn.电影=>filmv.拍电影

派生（Derivation）：通过加前缀和后缀构成另外一个词。

例如：happyadj.高兴的=>unhappyadj.不高兴的加前缀happyadj.高兴的=>happinessn.高兴

加后缀合成（Compounding）：由两个或更多词构成一个词。

例如：blackadj.黑的+boardn.板=>blackboardn.黑板Summary

借助构词法进行词义猜测在阅读文章的过程中，有些生词其实并不“生”，它们可能是我们所熟悉的词的“变体”。所以，可以尝试根据构词法来猜测这些词的含义。以下面段落中的红色词为例：Aftergraduatingin1953,heworkedasaresearcher.YuanLongpingrealisedthatlargerfieldswerenotthesolution.Instead,farmersneededtoboostyieldsinthefieldstheyhad.Howthiscouldbedonewasachallengingquestionatthetime.Yuanwasconvincedthattheanswercouldbefoundinthe

outputgreatly.Summary词义猜测解析：researcher是名词research（意为：“调查研究”）后面加了表示“人”的后缀“er”，所以，researcher的含义应该是做调查研究的人，即“研究员”。creation是动词create（意为：“创造”）后面加了表示名词词性的后缀“-tion”，所以，creation是名词“创造”。在self-pollinating中，“self-”这个前缀表示“自己的，自我的”；pollinate是动词“对……授粉”，后面加了“-ing”变成形容词词性。所以，self-pollinating该是形容词“自己授粉的”含义。output是介词out（意为“向外的”）和名词或动词put（意为“投，投掷，出发，放”等）构成的合成词，由于put的词义较多，单纯依靠构词法比较难猜测。结合上下文，“这种水稻使农民极大地提高了……。”，可猜到output是名词“产量”的含义。总结掌握构词法可以帮助辨认词类，了解词义，扩大词汇量，通过词与词的关系建立清晰的词汇概念，对提高英语语言能力有很大帮助。1.Thepricevaries___________(enormous)dependingonwherethewinewasproduced.
