李辉傻瓜英语总结：有些实意形容词，变成动词，直接在形容词后边加en（deep--deepen）,动词本身尾部有e,在形容词后加n(wide--widen);我只是随便找到以上几个，还有这样的很多。如:wooden 、golden。形容词动词化我发现的新课题，赖世雄老师对吗？！

形容词解释
一。只能用作定语，不能用作表语的形容词：little，wooden ，golden，many，elder 不能说The boy is little。the watch is golden/wooden
二、只能用作表语，不能用作定语的形容词：well，ill，alone,content，unable，worth，afraid，alive ,asleep, ashamed,awake, aware.
an ill boy ,an alone village 就是错的短语,an ill idea "坏点子"ill当定语时是转义了,不是"有病的"了。
三、表示倍数常用的句型:
He is as tall a boy as I.
He is a head taller than I .
He is two years older than I
China is four times as large as Europe.
I am twice as old as you
I am twice older than you.
I am twice the age of you.
My books are twice as many as yours
China is four times larger than Europe.
China is four times the size of Europe.
I pay twice as much as it was worth.
I pay twice as much for the house .
五.与动词有区别,表示延续状态的形容词:open,dead, still静,一动也不动,常修饰动词sit,stand
The door is open/closed.不要选opened或close.有特殊意义的形容词有:closed关,close形容词是"近",不是"关"了 near,nearly,hard,hardly,most,mostly大多数
六.very修饰原级形容词副词，修饰—ing，放在名词前表示强调。
much 修饰动词，修饰比较级最高级，修饰过去分词 。
四、--ly结尾一般是副词，但有些—ly结尾是形容词的：lonely，friendly，They talk in a friendly way.lovely，ugly，silly，likely，deadly，
五。在be，seem，及物当主语的look，taste。smell，feel，sound，appear等动词后用形容词，I looked at the flower. The flower looks beautiful. He appeared (出现)suddenly. He appeared(显得) happy.
六.表示主语长期的静止状态,不强调动作的sit,stand,lie 接形容词quiet,silent,still,red,peaceful等
The valley lay quiet and peaceful
She sat silent . They stood still.
七.become,fall ,get,go,turn 表示"变得"时后跟形容词.
The leaves fell/got/went/turned yellow.
It fell/got/went/turned cold.
八.present 表示"出席的,到场的"的时候常放在名词后,the members present 表示"现在的"则放在名词前 the present members
九.live有时可用做形容词: a live fish 活鱼(形容动物，不形容人 ) The broadcast comes to you live from Beijing .实况转播 That wire is live 电线是带电的 lively 生动的，活泼的。　　His class is often lively.
十.the +adj表示一类人,是复数
The rich should help the poor.
the blind /wounded/young/old
十一.多个形容词作定语时的位置:排列顺序大致为:all/quite/such/rather限定词(包括冠词、物主代词、指示代词、数词、不定代词等) + 描绘形容词(短词在前,长词在后)+ 特征形容词(包括大小、形状、新旧、年龄等)+ 颜色形容词 + 类属形容词(包括专有形容词和材料质地形容词) + 名词性定语(包括动名词)+ 名词。
