告诉我怎样让名词、动词、形容词、副词这四个词之间相互转化,请举词说明,马上中考了,讲得详细有重赏.

形容词、副词 之间的相互转化基本上是：形容词 adj+ly =副词adv,譬如：
kind, adj → +ly：kindly, adv
strong, adj → +ly：strongly, adv
一般以 ly结尾的词为副词,但也有少数特例,如：friend, n +ly = friendly, adj
动词以tion, sion, ment, ness, sure等结尾的变为名词
动词的过去式,一般可做形容词用；动词的现在分词（即-ing形式）,可做动名词或形容词,譬如：
shock, v → +ed（过去式）=shocked, adj（形容人的内心）震惊的,震撼的；+ing =shocking, adj（形容事物）令人震惊的,骇人听闻的
类似的还有：scare, scared, scaring; frighten, frightened, frightening; interested, interesting; pleased, pleasing, pleasure(n).
satisfy, v →satisfied, adj 满足的、满意的 →satisfying, adj 令人满意的、令人满足的 →satisfaction, n
amaze,v→ amazed,adj→ amazing,adj→ amazement, n
happy,adj→ happily,adv→ happiness,n
build, v→ building, n
teach,v→ teaching, n教导、教义
say,v→saying,n 俗话、谚语、格言 There is a saying that nothing comes easy.
等等,以上只是部分例举,中考基本上这几个形式就够用了的,上了高中建议最好参考下常用词缀的构成法,这样对扩展词汇很有帮助的.
