It is + adjective +‘of’...+(not)‘to’-infinitive 的结构及用法

在无锡市中考指导意见中的考试要求有语言知识点和语言技能。语言知识点中语法内容要求识记,理解和应用。所以在平时的学习中同学们必须完全掌握《考试大纲》中的语法项目。在9A Unit1,语法重要是It is + adjective +‘of...+(not)‘to’-infinitive, Verb to be + adjective + enough + ‘to’-infinitive.今天我在这儿主要讲的是It is + adjective +‘of’ ...+(not) ‘to’-infinitive.在讲这个知识点之前,我们先来看几个中考题。

【中考链接】

(1) It’s very nice ____you ____my parents your best wishes.(2011•无锡)

A. of; sending B. of; to send

C. for; to send D. for; sending

(2) ―The said sorry to me, but I wouldn’t listen.

A. forgive B. not forgive

C. to forgive D. not to forgive

(3) 在业余爱好上花些时间对我们来说是必要的。(2011•无锡)

It is necessary ________ on our hobbies.

要想解答上面的中考题,先来看9A Unit1 P13有这样一个句子:It is kind of your mum and dad to organize this party for us .你的父母亲能够为我们组织这么一个聚会真是太好了。1) to organize this party在这里不定式结构是作原因状语。不定式结构作状语通常可表示目的、结果、原因等意义。2) 本句中最主要的语法知识点在于It is + adjective +‘of’ ...+(not) ‘to’-infinitive这个结构。It实际上是一个形式主语,句子真正的主语是后面的不定式 to do sth.一般情况下,为了保持句子结构的平衡,为了避免主语过长,我们常常用it作句子的形式主语,而把真正的主语放在句子末尾。本句实际上等同于 To organize this party for usis kind of your mum and dad. 我们也可把他分解成两个简单句: Your mum and dad is kind .They organize this party for us.相信你通过下面的做做练练中一定能完全掌握这个句型。

一、 请同学们用这个句型做热身运动,合并下列句子

1. You are kind . You help me with my homework

____

2. Sandy is careless. She makes a lot of mistakes.

____

3. She is selfish. She cares only about herself.

____

4. He is silly. He does not forgive others for their faults.

____

5. Daniel is modest. He doesn’t show off in front of his classmates

____

相信你的答案一定是:

1. It’s kind of you to help me with my homework.

2. It’s careless of Sandy to make a lot of mistakes.

3. It’s selfish of her to care only about herself.

4. It’s silly of him not to forgive others for their faults.

5. It’s modest of Daniel not to show off in front of his classmates.

在上面的句子中出现的形容词kind, careless, selfish, silly, modest都是描述行为者的性格品质的形容词,在这个句型中强调行为者的性格品质的特征时用介词 “of ”。

二、 让我们巩固学到的句型,做一做下面翻译的练习

1. 你把报纸拿给我真是太好了。

____bring me the newspaper.

2. 你的父母亲为我们组织这个晚会真是考虑周到。

____this party for us.

3. 比利能想出这么多好点子真是富有创造性。(Billy)

____with so many good ideas.

4. 西蒙总是把东西弄得一团糟.

____such a mess.

5. 她不想到别人真是自私。

____others.

三、 同学们借你一双慧眼,请用of 或for 填空。

1. It is nice ____ you to help me.

2. It was generous ____ him to pay for the meal for us.

3. It was careful ____ the girl to look after her pet dog well.

4. It was clever ____ him to say good-bye.

5. It’s brave ____ Spiderman to help the weak.

6. It is easy ____ me to speak English.

7. It is quite difficult ____ the child to lift such a heavy box.

8. It was hard ____ him to mend the car.

9. It is important ____ a dancer to be healthy.

10. It’s necessary ____ us students to have sports for an hour every day.

思考1-5题中斜体的形容词和6-10题中斜体的形容词有什么不同?

很明显1-5题中斜体的形容词是描述行为者的性格品质的形容词,强调行为者的性格品质的特征所以我们用介词“of ”,6-10题中斜体的形容词是描述整个不定式的情况如何或怎样的形容词,这个我们已经学过,在强调整个不定式的情况如何或怎样时用介词“for ”。

通过上面的学习与巩固,一开始的3个中考题的答案一定很清楚了,他们是:

(1) 答案解析It’s+ nice/good/clever/careless/ careful of sb. to do sth.是个固定结构,同时这里的nice表示主观情感或态度的形容词,故答案选B。

(2) 答案解析It is + adj. + of sb. +(not)to do sth.的结构,根据句意:不原谅别人的错误是愚蠢的。故答案选D。

(3) 答案解析for us to spend much time(这里necessary表示客观情况的形容词)。

同学们让我们再练一练,相信你最棒,你会成功的!
