英语词性变换归纳及练习

一、名词变为形容词的方法

1. 在名词后面加-y可以变成形容词(尤其是一些与天气有关的名词)。例如：rain—rainy, cloud—cloudy, wind—windy, snow—snowy, health—healthy, luck—lucky等。

注意：1)如果名词以重读闭音节结尾，且词尾只有一个辅音字母，这时应双写词尾的辅音字母再加-y。如：sun—sunny, fun—funny等。

2)少数以不发音的e结尾的名词变为形容词时，应去掉e再加-y。例如：noise—noisy, ice—icy 等。

2. 一些抽象名词在词尾加-ful可以变为形容词。例如：care—careful, thank—thankful, help—helpful, use—useful, beauty—beautiful等。

3. 一些表示国家的名词可以在词尾加-ese, -ish或-n构成表示国籍、语言的形容词。例如：China—Chinese, Japan—Japanese, England—English, America—American, India—Indian, Australia —Australian(注意Canada—Canadian)。

4.在名词后加-ous变为形容词。例如：danger—dangerous等。

5. 在名词后加-ly变为形容词。例如：friend—friendly, love—lovely等。

6.在名词后加-less构成含有否定意义的形容词。例如：care—careless(粗心的)，use—useless(无用的)，hope—hopeless(没希望的)，home—homeless(无家可归的)等。

7. 一些以-ence结尾的名词，把ence改为ent变成形容词。例如：difference—different, silence—silent等。

二、动词变为名词的方法

1.词形不变，词性改变。例如：work, study, water, plant等可以用作动词，也可以用作名词。

2. 一些动词在词尾加上-er或-or之后就变成了表示“某一类人”的名词。例如：work—worker, teach—teacher, sing—singer, jump—jumper, play—player, learn—learner, visit—visitor, invent—inventor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)以重读闭音节结尾，且末尾只有一个辅音字母的动词，应双写末尾的辅音字母，再加-er。例如：run—runner, win—winner，begin—beginner等。

3. 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, wash—washing, swim—swimming, shop—shopping, begin—beginning等。

三、形容词变为副词的方法

一般在形容词的词尾加-ly可以变成副词。例如：quick—quickly, slow—slowly, loud—loudly, sudden—suddenly 等。但是，以下几点值得注意：

1. 一些以“辅音字母+y”结尾的形容词，要把y改为i再加-ly。例如：happy—happily, angry—angrily, lucky—luckily, heavy—heavily, noisy—noisily 等。

2. 有些以-ble或-le结尾的形容词，去掉e加-y。例如：possible—possibly, terrible—terribly等。

3. 少数以e结尾的形容词，要去掉e再加-ly。例如：true—truly等。但绝大多数以e结尾的形容词仍然直接加-ly。例如：polite—politely, wide—widely等。

4. 以-l结尾的形容词变为副词时仍然要在词尾加-ly，而不是只加-y。除非是以-ll结尾的才在词尾只加-y。例如：usual—usually, careful—carefully, useful—usefully, full—fully等。
