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 102 essays 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.

开始性疲劳是因为我们一直在拖延任务，而且我们拖延的越久，我们就会越觉得疲惫。故正确答案为A。
根据文章第二段最后一句 “And the longer we delay it, the more tired we feel.” 我们越拖延，我们越感到疲惫。
“start-up fatigue”理解不清致错。
作者针对开始性疲劳的解决方法就是：把最艰难的工作放在第一位处理。故正确答案为D。
根据文章第三段最后一句 “always handle the most difficult job first” 优先处理最困难的工作。
“handle”理解不清致错。
故B项正确。A项，意为“当一个人开始一项困难的任务之前”，C项，意为“如果这个工作相当无聊”，D项，意为“在找到解决办法之后”，均不符合文意。故正确答案为B。
根据第五段第二句 “Its difficulties appear so great that, however hard we work, we fail again and again” 可推断，能力型疲劳是尽管我们工作的很努力但是我们还是一遍又一遍的失败。故当所有的解决办法都失败的时候一个人会感到能力型疲劳。
未能精准定位“fail again and again”致错。
在“我”精疲力竭睡了一觉之后，“我”的脑海里清晰地出现了一个解决方法。故正确答案为D。
根据倒数第二段第一句 “An hour later, I woke up suddenly with the solution clearly in mind” 。
“clearly in mind”理解不清致错。
A项，意为“成功建立于失败之上”，B项，意为“怎样处理能力型疲劳”，D项，意为“疲劳：健康问题的早期信号”，均不符合文意。故正确答案为C。
文主要针对两种不同类型的疲劳作者给出了解释和解决办法，并通过自己的例子给出了证明。第一段和第二段是总领全文段落，引出两种不同的疲劳；第三段和第四段是对于“开始性疲劳”给出的定义、解决方法和作者自身的经历；第五段到第八段是对于“能力型疲劳”给出的定义、解决方案和自身经历，最后一段是对于中心的升华。由此可知，文章是关于克服疲劳走向成功的文章。
不能清楚的概括全文。
