解析：
1.C.
在文章的第二段开头和结尾部分我们可以找到答案： It’s easy for computer crimes to go undetected if no one checks up on what the computer is doing. The computer criminals who have been caught may have been the victims of uncommonly bad luck. 电脑犯罪是很容易的，而那些被抓住的也仅仅是因为他们运气不佳而已。所以说，很多电脑犯罪者可以逃之夭夭而不受惩罚是因为他们没有被发现。
2，A.
我们可以从第二段中找到答案：But it’s disturbing to note how many of the crimes we don’t know about were detected by accident, not by systematic inspections or other security procedures.
我们不知道有多少电脑犯罪事件还没有被发现。令我们头疼的是，已知的电脑犯罪是有多少是被偶然发现的，而不是通过系统检查或安全监控。
3.D.
Because company executives are afraid of the bad publicity that would result if the public found out that their computer had been misused. 公司的管理人员认为对于电脑犯罪事件的公开对他们自己也是一种颜面扫地的事情。所以也不愿意公开这样的事情。
4.C.
文章的最后一句话暗示了电脑犯罪者的前途：带着满意的介绍信，离开这家公司又可以再寻另外的地方继续犯罪。也就是说他很容易再找到另外一份工作。
5.B.
考察文章主旨。文章主要介绍了电脑犯罪现在很难通过程序来控制，而且犯了罪的人可以轻易逃脱，而不影响日后再另谋工作。

1. The method of scientific investigation is nothing but the expression of the necessary mode of working of the human mind: it is simply the mode by which all phenomena are reasoned about and given precise and exact explanations.
(nothing but只不过， by which=by the mode )
2. It is not that the scales in the one case, and the balance in the other, differ in the principles of their construction or manner of working; but that the latter is a much finer apparatus and of course much more accurate in its measurement than the former.
(not …but 不是而是，虽然相隔很远，但是句子的主干。)
3. You have all heard it repeatedly that men of science work by means of induction and deduction, that by the help of these operations, they, in a sort of sense, manage to extract from Nature certain natural laws, and that out of these, by some special skill of their own, they build up their theories.
(分辨句子的主干: You have all heard it that men work, that they manage to extract from Nature certain natural laws, that they build up their theories )
4. And it is imagined by many that the operations of the common mind can be by no means compared with these processes, and that they have to be acquired by a sort of special training.
(it is imagined by many在翻译为汉语的时候，注意其主语。)
5. probably there is not one here who has not in the course of the day had occasion to set in motion a complex train of reasoning, of the very same kind, though differing in degree, as that which a scientific man goes through in tracing the causes of natural phenomena.

1. 科学研究的方法只不过是人类思维活动地必要表达方式，也就是对一切现象进行思索并给以精确而严谨解释的表达方式。
2. 这并比意味着面包师和卖肉者所用的磅秤和化学家所用的天平在构造原理和工作方式上存在差别，而是说与前者相比，后者是一种精确的多的装置，因而在计量上必然更准确得多。
3. 你们都多次听说，科学家是通过归纳法和演绎法工作的，他们用这种方法，在某种意义上说，力求从自然界找出某些自然规律，然后他们根据这些规律，用自己的某种非同一般的本领，建立起他们自己的理论。
4. 许多人认为，普通人的思维活动根本无法与科学家的思维过程相比，认为这些思维过程必须经过某种专门训练才能掌握。
5. 大概这里不会有人一整天都没有机会进行一连串复杂的思考活动，这些思考活动与科学家在探索自然现象原因时所经历的思考活动，尽管复杂程度不同，但在类型上是完全一样的。
