it is+形容词+for或 of或 to do有什么区别
1,It is+adj.+of sb. +to do sth中的adj.跟sb.有关,
这个adj.是用来形容sb.的,
表示某人这么做真是太adj.了.
你会发现在这个句型中你把sb.和adj.提出来可以造个句sb. is(are) adj.
如It‘s very kind of you to help me.
把里面的sb.和adj.提出来可以发现you are kind是说得通的.
2,而It is +adj.+for sb.+to do sth表示做某事对某人来说很adj.
这里的adj.是do sth.的属性
里面的sb.跟adj.没有直接联系
如It‘s difficult for you to deal with the problem.
你就不能说you are difficult了吧
"It is+adj+of(for)+sb to do sth"在运用中,是用of ... to do sth还是for ... to do sth 呢?我们可以从以下六点来区别使用它们。
一、of... to do sth只能用在句中作主语,且主语常用it代替;而for... to do sth除在句中作主语 外,还可作表语、宾语、定语或状语。例如:
It is necessary for you to learn from others. 你必须向他人学习。(主语)
My suggestion is for you to go to Beijing University. 我建议你去念北京大学 。(表语)
I have a lot of work for you to do. 我有许多工作要你去做。(定语)
二、for... to do sth在句中作主语时,其表语可以是形容词也可以是名词;而of... to do sth作 主语时,只能接形容词做表语。例如:
It is impossible for you to get there in such a short time. 你在那么短的时间内到达那 是不可能的。
It will be a mistake for you to miss the chance. 你错过那个机会将是个错误。
It was too foolish of you to do so. 你那么做真是太愚蠢了。
三、 of... to do sth在句中作主语时,句子只能是"主语+be+表语";而for... to do sth在句中 作主语时,句子既能是"主语+be+表语",也可以是"主语+谓语+宾语"。例如:
It is impolite of you to fool your teacher. 你欺骗老师是不礼貌的。
It is possible for me to spend one hour finishing the job. 我花费一个小时去完成那项 工作是可能的。
It will take one hour for me to finish the job. 完成那项工作将花费我一个小时。
四、 在for... to do sth结构中,不定式的逻辑主语可以是人或物,也可以是引导词there;而 of... to do sth结构中,不定式的逻辑主语只能是人或物。例如:
It is important for you to study hard. 努力学习对你很重要。
It is a good idea for the book to be given to her. 把这本书送给她是个好主意 。
It is a pity for there to be any disagreement in the family. 家庭不和实为憾事。
It is wrong of you to tell a lie. 你说谎是不对的。
五、 在of... to do sth结构中,of后面的名词或代词与前面的形容词(kind, clever, foolish, selfish, polite, right, wrong, careful...)有逻辑上的主表关系;而在for... to do sth结构中, for后面的名词或代词与前面的形容词(easy, hard, difficult, possible, necessary, important, heavy...)没有逻辑上的主表关系。例如:
It is kind of you to lend me so much money. 你心肠真好,借给我那么多钱 。
It is hard for you to translate the sentence into English. 你把这个句子翻译成英语是有 困难的。
但是,当这个形容词可用来说明of后面的名词或代词的性质时,easy, hard, difficult等词 也可用于of... to do sth结构中。
The beautiful girl is easy to work with. 那个漂亮女孩很好共事。
六、 有些形容词(如nice ,right, wrong, good, wise 等)既可用于of... to do sth结构,也可用于 for... to do sth结构中;但两者之间的强调重点不同,意义也有区别。例如:
It is wise of them to turn down the suggestion. 他们很明智,拒绝了这个建议。
It is wise for them to turn down the suggestion. 他们拒绝这个建议是明智的。
前句强调them是wise的;后句强调to turn down the suggestion 是wise的。
1.
当形容词是可修饰人的形容词,即sb和adj.有主系表关系时,sb前用of.如 It’s clever of you to answer the
question so quickly./ It’s kind of you to help me a
lot.这样的形容词有:kind,nice,rude,clever,silly,foolish等.
2.当形容词是不可以修饰人的形容词,即
sb和adj.没有主系表关系时,sb前用for.如 It’s easy for her to clean the window by
herself./ It’s important for us to learn English
well.这样的形容词有:easy,hard,difficult,important,necessary,dangerous等.
后者 of 是属性,it's very nice of you to help me.=you're very nice to help me. 谢谢你帮我
能转换成sb is/are +形容词的 就是 It is+形容词+of sb to do sth
for是是对于这件事情,修饰的是to stop smoking is good
of是修饰的人.=you're very nice to help me,总不能说help me is
nice吧
而用“of”时,句中的形容词用来描述某人的品行。如It is very kind of to help me carry the box.(帮我搬这个盒子,你真是太好了。),重点强调“你真是太好了”,即“You are very kind”
it is kind of you to help me "你""帮助我"真是太"好"了
it is easy to cook "煮饭"很"简单"
