将下列英语译成中文(只可使用词典)：

Programming Languages

Ten years ago the proliferation of programming languages caused many people to foresee the development of a computer-age Babel where, in total ignorance of every other language, each programmer would learn only his own chosen language. That unhappy situation has not occurred for several reasons. First, effective efforts have been made to standardize particular languages such as Fortran and Cobol. It should be pointed out that pragmatic rather than scientific considerations motivated this standardization movement. However, the second reason that Babel has been averted is that computer scientists have begun to apply the scientific method to organize the classification, comparison, and appreciation ofvarious programming languages.

Due to the efforts of McCarthy (1962), Landin (1964), Strachey (1966), Wegner (1968), and others who provided insight into operational models of computation, we can now evaluate programming languages in terms of an unifying view of computation structures. Semantics and the expressive power resulting from modularity can now be studied in terms of the data structures and the accessing paths to them established during the execution of the control statements of the language.

Integrated Software

Convenience and saved time, work, and effort are the promises ofintegrated software. The antithesis of stand-alone packages, integrated software delivers a collection of applications based upon a common user interface and sharable data.

In its most common form, the integrated product includes a word processor,a spreadsheet, and some form of database. Many packages add telecommunications, presentation graphics, and outline modules. Comprehensive products throw in desktop accessories such as calculators, calendars, DOS shells, and other utilities.

Even when stand-alone products are from the same vendor, it can be frustrating trying to move information between applications or simply trying to remember which key to press to call up the menu, That is why integrated packages appeal to many users, particularly novices. Using an integrated product saves you the headache of trying to move data in a Brand X word processor to a Brand Y spreadsheet. And because the integrated package is a single product from a single vendor, training, support, and upgrades also are made simpler. [试题解析]

第9题

There is no doubt that adults, and even highly educated adults, vary gready in the speed a

nd efficiency of their reading. Some proceed very slowly throughout; others dash along too quickly and then have to regress. Poor readers in particular may lack the ability to vary their manner of reading according to the type of reading matter and to their intentions in reading it. A good reader can move at great speed through the text of a novel or similar light reading matter. He may be able to skim a page, picking up a word or two here and there, and gain a general idea of what the text is about without really reading it. In reading more difficult material, with the intention of taking in the whole of it, he will proceed more slowly, but even then he will vary his pace, concentrating on the key words and passages , perhaps re-reading them several times and pass more quickly over the remainder. A less efficient reader tends to maintain the same speed whatever the material he reads.Consequendy, even light reading matter gives him little pleasure because he reads so slowly. But this pace may be too fast for really difficult material which requires special concentration at difficult points. A type of reading which necessitates careful attention to detail is proofreading, in which the reader, in order to detect misprints in a sample print, has to notice not so much the meaning of what he reads as the exact shape and order of letters and words in the text. This is extremely difficult for most people, since they are accustomed to overlooking such details. In fact, considerable practice is required to practice this task efficiently and it can be done only by reading very slowly, and by paying comparatively litde attention to the general meaning of the text.

The author claims that there is a difference in reading speed______.

A．among readers who have different experience

B．among all the readers

C．between the poorly educated and the highly educated

D．among the highly educated people
