一、too... to ...的意义 too...to...句型形式是肯定的,但表达否定意义,表示"太……而不能……"。too的后面接形容词或副词的原级,to的后面接动词原形,构成动词不定式。too...to...句型是简单句。例如: He is too young to join the army.他年龄太小,不能参军。 二、动词不定式的逻辑主语 动词不定式所发出的动作,其执行者与整个句子的主语不同指一个人或物时,需要在动词不定式前加上一个逻辑主语(for sb.)。例如: The maths problem is too difficult for me to work out.这道数学题太难我不能解出它。 三、too...to...结构表示肯定意义的情况 1. too前面含有表示否定意义的词,例如: not, never, nothing等时,too... to...结构不表示否定意义。例如: One is never too old to learn.活到老,学到老。 2.如果在too...to...结构的前面出现了only,不仅免去了其否定意义,反而加强了它的肯定语气,only too相当于very或very much。例如: I shall be only too pleased to get home.我将极高兴地回家。 3. too后为表示情感的形容词,例如:glad, pleased, happy, sad等时,表示的是肯定意义。例如: He is too sad to hear the bad news.听到不幸的消息他太悲伤了。 四、too...to...结构与... enough to...结构及so...that...结构的相互转换 1.将too...to...结构转换为...enough to...结构时要注意:①enough前的形容词或副词须是too前面形容词或副词的反义词;②...enough to ...句式须用否定式;③too...to...结构有逻辑主语时,...enough to...结构也要加上逻辑主语。例如: She is too young to do the work.→She isn't old enough to do the work. 2.将too...to...结构转换为so...that...结构时要注意:①so...that...结构是复合句,so的后面接形容词或副词,that的后面接从句;②that后面的从句要用否定形式。例如: She is too young to do the work.→She is so young that she can't do the work.
