英语单词词性转换规则
一、动词(v.)→名词(n.)

visit—visitor, invent—inventor,collect—collector等. 注意:1)以不发音的e结尾的动词,在词尾加-r. 例如:drive—driver, write—writer等.
2)以辅音字母开头并以元音字母加辅音字母结尾的单词,应双写末尾的辅音字母再加er。
例如:run—runner, win—winner,begin—beginner等.
2.在动词词尾加上-ment 变成名词
例如:achieve—achievement (成就)
advertise—advertisement//advertising(广告)
agree—agreement disagree—disagreement amuse—amusement (娱乐) improve—improvement(争吵) commit(奉献)—commitment develop—development (发展) 有些单词比较特殊,需把动词后的e去掉再加ment. 例如:argue—argument(争论)
3.在动词词尾加上-(t)ion/(s)ion变成名词
例如: attract—attraction; instruct—instruction;
invent—invention discuss—discussion; express—expression educate—education;
graduate—graduation; operate—operation (去e再加"ion")
compete—competition; organize—organization (把e改成其他字母再加"tion") decide—decision conclude—conclusion (把de改为s再加"ion") describe—description描写,描绘 (这是特例,不规则变化)
4.在动词词尾加上-ance变成名词 例如: appear—appearance (外貌;出现) perform—performance (演出) accept—acceptance (接受)
5.在动词词尾加-ing变成名词 (方法与动词变为现在分词的方法相同)
例如:meet—meeting build—building wait—waiting bathe—bathing say—saying(谚语) mean—meaning
注意:以辅音字母开头并以元音字母加辅音字母结尾的单词,应双写末尾的辅音字母再加
-ing

sit(坐)—seat (座位) succeed—success(成功) tour—tour(旅游)/ tourist (游客)
二、动词(v.)→形容词(adj.)
1.动词后面加able,以e结尾的动词则去e加able,表示具有此性质,特点或属性. 例如: afford-affordable;love-lovable
2.动词后面加ed,以e结尾的动词则直接加d,表示被动性的属性或特点. 例如: scatter-scattered use-used
3不规则的动词则必须记忆,记住其过去分词形式.规律不大,意义同(b).

如: noise—noisy, ice—icy, shine—shiny(发亮的), taste(口味)—tasty(甜的)
2.名词后面加-ed,以e结尾的直接加d.
例如: spot(斑点)—spotted(有斑点的); talent—talented (有天赋的) organize—organized 有组织的; balance—balanced(平衡的)
3.一些抽象名词在词尾加-ful可以变为形容词
