【考点】O5：科教类阅读；P3：深层含义；P5：猜测词义
【分析】一项实验表明﹣﹣从小帮忙做家务和其他事情的孩子，长大后也不会太差，甚至非常出色．本文先从一个叫John的男孩的事例开始说起．John从小就要帮忙做事情，其他小朋友都很同情他．然而，等他长大后，他却大有作为﹣﹣有满意的工作，幸福的婚姻，健康的体魄而且生活得更加快乐．Vaillant的实验时长40年，在这 40年里，对456名来自波士顿的青少年进行了长期的跟踪．最后发现﹣﹣从小开始帮忙做事的孩子建立起了较强的责任感，独立，自信以及其他能力，这些孩子能够容易与更广泛的人群建立良好的人际关系，能够获得丰厚的收入以及解决问题的能力﹣﹣知道如何与人协作以达到共同的目标．因而，从本文可知，无论什么年龄，有事做都非常重要，从小就需要培养孩子的做事能力．有能力的人知道怎样与人合作，以及知道工作并不是一切，高情商是获得精彩人生的必需
【解答】46．A 细节理解题．由原文第一段可知，John 长大后有了美满的婚姻和生活．B项没有提及；C 项没有提及父母让 John 做各种事情的目的，但从全文可以知道，是为了锻炼他的能力；D 项错误，由第一段原句可知 other kids felt sorry for him，是为他难过
47．D 分析理解题．原文第二段找到 Villiant 的话，Boys who worked in the home or community gained competence and came to feel they were worthwhile members of society
（在家里或社群里获得能力的孩子会感受到自己的社会价值），以及最后一句 Andbecause they felt good about themselves，others felt good about them（因为他们对自己的感觉良好/对自己的肯定度高，所以别人也对他们的感觉良好），因而是解释孩子们感觉良好的原因，故选D
48．C 细节理解题．由第三段 Points were awarded for part﹣time jobs，housework，effort in school，and ability to deal with problems．可知，分数奖励自兼职，家务劳动，在学校 的表现以及解决问题的能力．因而，答案为C
49．C 推理判断题．由 sharp 这个句子后面紧接着的句子提到的数据和内容可知，从小做事情和长大后成为什么样的人之间的联系非常明显．故 sharp 意为 clear anddefinitely．故选 C
【答案】B
【解析】深层理解题．最后一段 The most competent adults are those who know how to dothis．Yet work isn't everything．（有能力的人知道怎样与人合作，以及知道工作并不是一切），可知，表达的同样的意思是﹣﹣高情商是获得精彩生活的必需．故选B
【点评】考生需要了解作者的写作结构及写作目的﹣﹣先从一个男孩的事例说起，再到Villiant的实验，用实验来说明，最后提出观点﹣﹣懂得与人合作，是获得精彩人生的必需
20．（12.5 分）Failure is probably the most exhausting experience a person ever has．There is nothing more tiring than not succeeding
We experience this tiredness in two ways：as start﹣up fatigue（疲惫） and performance fatigue．In the former case，we keep putting off a task because it has either too boring or too difficult．And the longer we delay it，the more tired we feel
Such start﹣up fatigue is very real，even if not actually physical，not something in our muscles and bones．The solution is obvious though perhaps not easy to apply：always handle the most difficult job first
Years ago，I was asked to write 102essays on the great ideas of some famous authors．Applying my own rule，I determined to write them in alphabetical（按字母顺序），never letting myself leave out a tough idea．And I always started the day's work with the difficult task of essay﹣ writing．Experience proved that the rule works
Performance fatigue is more difficult to handle．Though willing to get started，we cannot seem to do the job right．Its difficulties appear so great that，however hard we work，we fail again and again．In such a situation，I work as hard as I can﹣then let the unconscious take over
When planning Encyclopaedia Britannica （《大英百科全书》），I had to create a table of contents based on the topics of its articles．Nothing like this had ever been done before，and day after dat I kept coming up with solutions，but none of them worked．My fatigue became almost unbearable
One day，mentally exhausted，I wrote down all the reasons why this problem could not be solved ． I tried to convince myself that the trouble was with the problem itself， not with me．Relived，I sat back in an easy chair and fell asleep
An hour later ， I woke up suddenly with the solution clearly in mind ． In the weeks that followed，the solution which had come up in my unconscious mind provided correct at every step．Though I worked as hard as before，I felt no fatigue．Success was now as exciting as failure had been depressing
Human beings，I believe must try to succeed．Success，then，means never feeling tired
