A、they are able to adapt to life in extremely dry environments.
B、their original life form was a kind of primeval bacteria.
C、they have so much in common with sea turtles.
D、they have made the transition from sea to land more than once.
In the first form, known as primary cooperation, group and individual unite. The group contains nearly all of each individual's life. The rewards of the group's work are shared with each member. There is an interlocking identity of individual, group, and task performed. Means and goals become one, for cooperation itself is valued.
While primary cooperation is most often characteristic of preliterate societies, secondary cooperation is characteristic of many modem societies. In secondary cooperation, individuals devote only part of their lives to the group. Cooperation itself is not a value. Most members of the group feel loyalty, but the welfare of the group is not the first consideration. Members perform. tasks so that they can separately enjoy the fruits of their cooperation in the form. of salary, prestige, or power. Business offices and professional athletic teams are examples of secondary cooperation.
In the third type, called tertiary cooperation or accommodation, latent conflict underlies the shared work. The attitudes of the cooperating parties are purely opportunistic; the organization is loose and fragile. Accommodation involves common means to achieve antagonistic goals; it breaks down when the common means cease to aid each party in reaching its goals. This is not, strictly speaking, cooperation at all, and hence the somewhat contradictory term antagonistic cooperation is sometimes used for this relationship.
What is the author's main purpose in Paragraph 1 of the passage?
A.To explain how cooperation differs from competition and conflict
B.To show the importance of group organization and attitudes
C.To offer a brief definition of cooperation
D.To urge readers to cooperate more often

从供选择的答案中选出应填入下面一段英文中______内的正确答案。
Video RAM means in general all forms of RAM used to(1). image data for the video display monitor. Somewhat confusingly, the most common(2)of video RAM is called Video RAM (VRAM). All types of video RAM are special(3)of dynamic RAM (DRAM). Video RAM is really a buffer(4)the processor and the display monitor and is often called the frame buffer. When(5)are to be sent to the display, they are first read by the processor as data from some form of main storage RAM and then(6)to video RAM. From video RAM (the frame buffer), the data is converted by a RAM digital-to-analog converter (RAMDAC) into analog(7)that are sent to the display presentation mechanism such as a cathode ray tube (CRT). Usually, video RAM comes in a 1 or 2 megabyte package and is(8)on the video or graphics card in the computer. Most forms of video RAM are dual-ported. While the processor is writing a new image to video RAM, the display is reading from video to(9)its current display content. The dual-port design is the main(10)between main storage RAM and video RAM.

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]
