A.小议too...to结构

《大学英语》第二册第十单元课文前面有这样一句话:Are we too quick to blame and slow to praise?看到这个句子,你一定会想到too...to结构,此句可以套用too...to结构来理解吗?下面我们就来学习有关too...to结构的情况.
一、too...to结构通常表示否定意义,意思是"太……不能","太……不会".例如:
It's too early for us to go yet.现在太早了,我们不会去的.
1.too...to结构相当于so...that...not.例如:
It is too late for us to catch the train.→It is so late that we can not catch the train.太晚了,我们赶不上火车了.
2.有时候,当too...to do结构中的do既可作及物动词,又可作不及物动词时,含有too...to结构的句子往往产生歧义.例如:
Tom is too selfish to help.→Tom is too selfish to help others.汤姆太自私了,不会帮助别人.→Tom is too selfish to be helped by others.汤姆太自私了,别人不会帮助他.
3. too...for也表示否定意义,相当于too...to,意为"太……不适合(不能)".例如:
He is too young for the work.=He is too young to do the work.他太年轻,不适合这份工作.
It's too cold outside for jogging.=It's too cold outside to go jogging.外面太冷了,不能去跑步.
二、too...to结构并不一定都表示否定意义,遇到下面几种情况时,too...to结构表示肯定意义.
1.当too前面有only, all, not, but, never, simply, just等词时,too...to结构表示肯定意义.例如:
I am only too pleased to see you.非常高兴见到你.
You know but too well to hold your tongue.你深知少说为妙.
2. 当too后面是 eager, anxious, pleased, kind, willing, inclined, ready, glad, quick等词时,too...to结构表示肯定意义.例如:
I am too eager to go there. 我太想去那里了.
3. too...to结构的否定形式表示肯定意义,有两种变法:
一是在too前加not,构成not too...to,通常否定整个too...to结构而表示肯定含义,意为"并不太……,所以能……".例如:
The article is not too difficult to translate.这篇文章并不太难,很容易翻译.
She is not too angry to speak up. 她不太生气,能够说出话来.
另一种方法是在不定式to do前加not,通过否定不定式而表示肯定含义,大致相当于so...that one can,意思是"太……一定能(不可能不)……"、"太……忍不住(不免)……".例如:
He is too clever not to understand the importance of this question.=He is so clever that he can understand the importance of this question.他太聪明了,一定能(不可能不)懂得这个问题的重要性.
She was too angry not to say what she thought.=She was so angry that she could not but say what she thought.她太气愤了,忍不住要说出心里的话.
看过上面的内容,我们再来看看《大学英语》第二册第十单元课文前面的这句话:Are we too quick to blame and slow to praise?这个句子当然可以套用too...to结构来理解,但它属于第二种情况,表示肯定意义.此句应译为:"我们是不是指责太快而表扬太慢了呢?"

B.too...to 结构表示肯定含义的情况
【too...to 结构表示肯定含义的情况】
我们知道too...to结构一般表示否定含义,意为"太...以致于不能"
eg:He is too old to work.
但too...to在下列情况下却表示肯定含义:
⑴当too前或to前有否定词构成双重否定时.
eg:English is not too difficult to learn.
英语并不太难学.
He is too wise not to see that.
他很聪明,不会不懂这一点.
⑵当too后是glad,pleased,happy,delighted,satisfied,ready,willing,kind,apt,
good,true,easy,near,careful,well,early,delicious,eager,anxious等形容词或副词时.
eg:They are too anxious to leave.
他们急于离开.
He is too ready to help others.
他总是乐于助人.
与这些词连用时,too前还常加上only,all,but,just,simply等副词,意思不变,因为这些词加上too后与very同义.
eg:I'm only too glad to see you .
见到你非常高兴.
They are but too pleased to hear the news.
他们听到这个消息,非常高兴.
⑶与cannot连用时.
eg:You cannot be too careful(=You can never be careful enough) to do your homework.
你做作业越仔细越好(=无论怎样仔细也不过分).
⑷当不定式在句中作定语或真正的主语时.
eg:There are too many problems to be solved.
有很多问题有待解决.
It is too much to say that he is a fool.

够全！
