What is the difference between these sentences
It is important for us to learn English well.
“It is + adjective + for + noun/pronoun + to + verb”句型中，形容词通常是描述事物的，修饰的对象是动词不定式。这个句型往往用于表达对某人如果做某件事情的看法，说话时这个动作可能并未完成。
It is very nice of you to lend me an umbrella.
“It is + adjective + of + noun/pronoun + to + verb”句型中，形容词多是描述人物的性格、品质的形容词，修饰的对象是句子的逻辑主语，即of后的名词或代词。而且，在说这句话之前，句中的那个动作通常都已经完成。

语言技能 通过比较的方法，理解和区别相关形容词句型间在含义和用法上的差别。
情感态度 主动探究，善于发现语言的规律并能运用规律举一反三。
学习重点 学习有关形容词的三个句型。
学习难点 区分“It is + 形容词 + for + 名词/代词 +动词不定式”和学习“It is +形容词 + of + 名词/代词 +动词不定式”这两种句型的含义和用法。
温故知新
用句型“It is + adj. + for/of sb. (n. /pron.) + to do sth.”完成下列句子。
1. very important / students / learn/English
______________________________________________________________________________
2. kind / Tom / help the old people / go across the road
______________________________________________________________________________
3. brave / the firefighters / put out / the big fire
______________________________________________________________________________
4. nice / you / give me a hand
______________________________________________________________________________
5. good / you / eat / more vegetables
______________________________________________________________________________
形容词的有关句型
1. 句型：It is + adj. + for sb. (n. /pron.) + to do sth.
It is+adj.+for+sb.+to do sth.= To do sth.+is+adj.+for sb. 意为“做某事对于某人来说是……的”。
该句型中的形容词用来描述事物，常见的此类形容词有：difficult，convenient，important，impossible，possible，necessary，easy，hard等。
It's difficult for us to fall asleep. =To fall asleep is difficult for us. 我们很难入睡。
It's impossible for us to find the lost boy. =To find the lost boy is impossible for us. 我们不可能找到那个失踪的男孩。
2. 句型：It is + adj.+ of sb.(n. /pron. ) + to do sth.
It is+adj.+of sb.+to do sth.=sb.+be+adj.+to do sth. ,意为“某人做某事是……的”。该句型中的形容词用来描述不定式行为者的品质、特点等，常见的此类形容词有：nice，kind，polite，rude，clever，good，foolish，wise，wrong，cruel等。

It's foolish of you to believe him. =You are foolish to believe him. 你相信他的话真的是太傻了。
【拓展】for 与of 的辨别方法：
(1)当句中的形容词用来说明人的性格或品质时，我们选用介词of。
It is very clever of you to go with us.=You are very clever to go with us. 你和我们一起去，真是太聪明了。
(2)当句中的形容词用来说明不定式时，我们选用介词for。
It is very important for us to learn English.=To learn English is very important for us. 学英语对我们来说很重要。
3. 句型：adj. + enough + to do sth.
adj.+enough+to do sth. 意为 “足以……去做某事”。
enough是副词，修饰前面的形容词，表示程度，enough后面的动词不定式表示结果。
The boy is tall enough to reach the book on the shelf. 这个男孩足够高，能够得着架子上的书。
The towel is soft enough not to damage my skin. 这条毛巾足够柔软，不会伤害我的皮肤。
【拓展】not … enough to=too … to 太……以至于不能……
