在有了足够的词汇量、较为完备的语法知识和句法结构知识之后，接下来就是对每节课所学习的词汇进行扩展，如利用联想的手段，进一步了解与某个特定词汇相关的同义词、近义词、反义词，派生词等。
学习者要明白词形转换一般主要有两个方面：一是曲折变化，就是指名词的复数形式-s，-es；动词的单数第三人称-s，-es；动词的现在分词-ing；动词的过去分词-ed；以及形容词和副词的比较级-er，或者more，最高级-est或者most。
另一方面是派生变化：包括前缀法（一般改变单词的词义，不改变单词的词性）和后缀法（一般改变单词的词性）。
当然，其中还包括多个单词的合成法，这也是词形转换考题中不可忽视的一部分。
掌握词形转换的基本规律之合成法（1）直接合成①形容词+名词——名词：sweetheart，恋人，情人；gentlemen,绅士；newcomer,新来的人；briefcase,公文包。
②形容词+名词——形容词：short-term,短期的；first-rate,一流的；first-hand,一手的；high-grade,高年级的。
③名词+名词——名词：notebook,笔记本；sunglasses,太阳镜；newspaper,报纸；headline,标题；thumbnail,图钉；gravestone,墓碑；fireplace壁炉。
④名词+形容词——名词：airtight,密封的；snow-white,雪白的；self-confident,自信的；color-blind,色盲的；seasick,晕船的；blood-red,血红的；home-sick,想家的；coal-black, 煤黑的；ice-cold,冰冷的。
⑤动词+ 副词——名词：feedback,反馈；sit-in,**；set-up,组织；check-out,结账；take-off,起飞；breakthrough,突破；comeback，回归。
（2）先变化后合成①名词+及物动词+ er——复合名词：best-seller,畅销书；lie-detector,测谎仪；lady-killer, **；type-writer,打字机；tape-recorder,录音机；pain-killer,止疼药；watch-maker,手表制造商；record-holder,纪录保持者；tax-payer,纳税人。
高中英语词形变换汇总(1)直接加-s.如：book→books， pen→pens， ruler→rulers， watch →watches， phone→phones.(2)以 s， x， ch， sh结尾的加-es.如：bus→buses， box→boxes，brush→brushes， watch→watches.(3)以辅音字母加 y结尾的改 y为 i再加-es.如：family→families，baby→babies.(4)以元音字母加 y结尾的直接加-s.如：boy→boys， toy→toys.(1)有些名词的复数形式是不规则的，必须熟记。
如：child→children，foot→feet， tooth→teeth， goose→geese， mouse→mice， man →men， woman→women等。
(2)单复数同形的名词。
如：fish(鱼)，deer(鹿)，sheep(绵羊)，works(工厂)，means(方法)等。
在动词后面加-s。
如：play→plays， like→likes， do→does， teach →teaches.在动词词尾加-ed。
如：clean→cleaned， visit→visited， work→worked， look→looked.有些动词的第三人称单数形式是规则的，如go→goes， do→does，see→sees等；有的不规则，如have→has。
