It is well that young men should begin at the beginning and occupy the least important positions．21 of the leading businessmen of Pittsburgh had a serious responsibility placed upon them at the very 22 of their career．They were 23 to the broom(扫帚), spending the first hours of their business lives 24the office．
And here is the basic 25 of success, the great secret: 26 your energy, thought, and capital (资本) wholly on the business in which you are 27．Having begun in one line, determine to fight it out on that 28, to lead in it, adopt every 29 , have the best machinery, and know the most about it．
The companies which fail are those which have 30 their capital, which means that they have scattered their brains 31．They have investments in this, or that, or 32 , here, there, and everywhere．“Don put all your eggs in one basket” is all 33, I tell you．“Put all your eggs in one basket, and then 34 that basket”．Look round you and take 35; men who do that do not often fail．It is easy to watch and carry the one basket．It is trying to carry too many baskets 36breaks most eggs in this country．He who 37 three baskets must put one on his 38, which is likely to fall down．One 39 of the American businessman is lack of concentration．
Remember: put all your eggs in one basket, and watch that basket． 40 Emerson says, no one can cheat you out of final success but yourselves．

解析：
谁不想成功呢？你知道成功的秘诀是什么？获得成功的首要条件和最大秘诀是：把精力和财力完全集中于所干的事业上。一旦开始干那一行，就要决心干出个名堂，要出类拔萃。集中精力，把所有鸡蛋放进一只篮子并照管好那只篮子；最后，不要失去耐心，因为正如爱默生所说：“除了你自己以外，没有人能哄骗你离开最后的成功”。
21．D结合上下文的语境应该是“匹兹堡有许多大企业家在创业之初都肩负过重任”。
22．A文章开头说年轻人应该从头做起，因此本题选A，at the beginning of“在……之初”。
23．C 他们起初被安排去做卫生。
24．A与前面的broom呼应，这里表示他们被安排去做卫生，上班的几个小时就打扫办公室。
25．B从下文的叙述判断选B，用condition表示“条件”：获得成功的首要条件和最大秘诀。
26．A从后面的介词搭配判断选A，用concentrate…on表示“专心致志于”，其它动词选项的搭配为：devote…to, apply…to, bury…in。
27．B本题用be engaged in表示“忙于做某事”，相当于be occupied in doing/ with sth．。
28．D从语境判断本题选D与前面的Having begun in one line呼应。
29．A语境表示采纳各种进步与改进。本长句的含义：把精力和财力完全集中于所干的事业上。一旦开始干那一行，就要决心干出个名堂，要出类拔萃，要点点滴滴地改进，要采用最好的机器，要尽力通晓这一行。
30．D与下文的scattered呼应，本题选D：失败的企业是那些分散了资力，因而意味着分散了精力的企业。
31．A本题用also用于肯定句，修饰动词或整个句子内容，而either用于否定句的末尾，neither本身表示了否定，多用于句首，yet多用在完成时态的否定句的句末或放在句子的中间表示“然而”。
32．B与前面的this or that呼应，这里用the other(one)。
33．C从下文的叙述可知作者在批驳这句话，因此选C。
34．D从下文的“It is easy to watch and carry the one basket．”可知本题选D。
35．A这里用take notice表示“注意”：注视周围并留意看看，能这样做的人往往不会失败。
36．B本题是强调句结构：正是要拿的篮子太多才会使你的鸡蛋被打破。
37．C前面的carry已经暗示本题的答案。
38．C有三只篮子的人，两手各拿一个，另外一只就只能顶在头上，而这只篮子就很容易被摔倒。
39．A美国企业家的一个错误就是缺少集中。
40．D这里用as引导定语从句，as在从句中作宾语，指代主句的内容。整个句子的意思为：正如爱默生所说：“除了你自己以外，没有人能哄骗你离开最后的成功。”
