用of还是for

在以某些形容词作表语时,句子的真正主语是一个动词不定式,我们常用代词it作句子的形式主语,而将其真正的主语动词不定式移到表语形容词后面。这时,不定式前常用介词引出不定式的逻辑主语。例如:1.It is wiseforhi mto get away.他走开是明智的。2.It is wiseofhi mto get away.他很明智,他走开了。不少同学不知如何选择of和for,对这两个介词所引导的逻辑主语在意义上有何差异感到很难理解。本文想就这一问题作一点探讨,仅供参考。一、分清两类不同的形容词第一类:easy,hard,difficult,i mport-ant,necessary,possible,i mpossible等。这类…

用for还是用of

在中学英语教材中，常常看到下面类型的句子： 　　It's very difficult for me to do it.　　It's very nice of you to lend me the bike.　　“ for＋ n.(pron.)＋动词不定式”这种结构叫做动词不定式复合结构， for后的名词或代词是动词不定式的主语，它与动词不定式 (短语 )之间具有逻辑的主谓关系。什么时候要用 of代替 for呢 ?　　如果句中用描写人物特征或品德的形容词作表语时，就要用以 of引导的动词不定式复合结构。例如，下面句子中的介词 of都不能改为 for： 　　It is stupid of him to do that.(他做那事真愚蠢。 )　　It …

Exploration of Causes for Tess''s Tragedy

A general social appearance that a great 1iterature works unfold is more abundant,specific and real than provisions of politics,history and philosophy give us.Just as Karl Marx says."The briIiiant contemporary school of novelists in England.whose eloquent and graphic portrayals of the-world have revealed more political and social truths than all the professional politicians.publicists,and moralists put together,had described every section of the middle class of ‘most respectable' pensioners and holders of government bonds,who look down on all kinds of business as something vulgar,down to the stall shopkeepers and lawyers' clerks",when he commented on the great critical realists of the 19th century.It is Thomas Hardy who was a great literature rriter in late 19th century,and his novels enjoyed great prestige among the people at that time.In his novel,Tess of the d'Urbervilles,Tess was a tragic character.Deliberating the whole novel,such a conclusion can be drawn:It was necessary to couse Tess's tragedy.She was not only the victim in Victorian time,but also the victim of the contemporary,which including her helpless parents,cruel inducer,Alec.and her nominal husband,Angel Clare.Unlucky Tess's fate urge me to explore the causes for the tragedy.

用for还是用of?

不定式的复合结构“Itis＋adj＋for（of）＋n．（sb．）＋todo”这一句型中，形容词后的介词何时用for，何时用of，这个问题一直困扰着大多数英语初学者。在这一句型中，it是形式主语，形容词是表语形容词，for（of）这一介词后的名词或代词实际上是这一形式的逻辑主语，这是一个复合不定式作主语的句型。在此句型中，如果表语形容词是指行为的性质（thenatureofanacfion），也就是说，如果这个表语形容词能修饰介词后的名词或代词，介词就用of；如果表语形容词不能修饰介词后的名词（代词），它表明动词不定式的动作是谁发出时，就用for。…     

不定式for结构和of结构

不定式是一种非谓语动词,不能单独作谓语,因此没有语法上的主语。但由于不定式表示的是动作,在意义上可以有它的主体。我们称之为逻辑主语。提起不定式逻辑主语,人们首先想到的会是“for 名词(宾格代词) 不定式”的复合结构。如:It is important for us to study English well.然而,有时不定式的逻辑主语须要用“of 名词(代词宾格)”才行。例如:It is kind of you to help me.而不能说:It is kind for you to help me.
