(二).Translate the following paragraphs into Chinese.(将下列各段翻译成汉语)。
1.The central processing unit (CPU) is the heart of the computer systems. Among other things, its configuration determines whether a computer is fast or slow in relation to other computers. The CPU is the most complex computer system component, responsible for directing most of the computer system activities based on the instructions provided. As one computer generation has evolved to the next, the physical size of the CPU has often become smaller and smaller, while its speed and capacity have increased tremendously. Indeed, these changes have resulted in microcomputers that are small enough to fit on your desk or your lap.
2.Personal computer software is based on specific operating systems and machines. Operating systems software defines the ‘personality’ of the computer by specifying the way in which programs are controlled, files are stored and retrieved, and how the system’s hardware components are held together. Software written to run on a specific PC operating system can’t run on another. To use PCs effectively, one must understand the capabilities of their operating systems software.
3.An application software (also called end-user program) is any program designed to perform a specific function directly for the user or, in some cases, for another application program. Examples of application software include word processors; database programs; Web browsers; development tools; drawing, paint, and image editing programs; and communication programs. Figuratively speaking, application software sits on top of system software because it is unable to run without the operating system and system software.

9. Object-orientation may increase productivity because OOA and OOD, if done correctly, result in products that are cleaner, more understandable, and easier to implement and test.
10. Functional testing tests whether the output is the expected result with the valid input.
(二).Translate the following paragraphs into Chinese.(将下列各段翻译成汉语)。
1. SQL Server is a RDBMS (Relational Database Management System) made by Microsoft. This means that the data is stored in two dimensional tables. RDBMSs all have tables called catalogs or dictionaries that contain information about the particular databases. SQL Server is designed to allow thousands of users to access the database at the same time and is a true client/server database system. It is much more secure than Access. Rights can be assigned to individual users and administrators. For example you can setup one user that can only insert data in the database but cannot delete any.
2. A high-level language is an artificial language with which we can write various instructions. This is possible not because computer processors are now so technologically advanced that they can ‘understand’ these languages. You should translate from programming languages into machine language which can be understood by the computer processors. Compilers can accomplish this task. This does mean that a high-level language program is not directly executable: it must be compiled to produce processor program, which is executable.
3. Over the last few decades there has been a tremendous growth in information technology and its impact on everyday life. Complex software systems have become critical to the operation of many systems in areas such as banking, communications, manufacturing, power generation, and transportation. Progress in computer science and accumulated experience with industrial production of software have led to the emergence of software engineering as a separate discipline. The software engineering discipline has been defined as "the application of systematic, disciplined, quantifiable approaches to the development, operation, and maintenance of software." that is, the application of engineering to software.

We will discuss the topologies of networks first, and then touch on some hardware issues, including the network devices and the types of transmission media involved.Communication networks can be classified in terms of their physical arrangement or Topologies. Three common topologies are the star, bus, and ring.

3.The basic concept of a data warehouse is the difference between data and information. Data is composed of facts that are often found in certain systems, such as data on student information at a university. In a data warehouse environment, data is only valuable when it is organized and displayed as information. Information is an integrated collection of facts and is used as the basis for decision making. The data warehouse is the data environment that can be used as the single integrated source of data for processing information.
