Uint4（1）Inheritance in object-oriented programming allows a class to inherit properties(性能，道具) from a class of object.（2）The language used 0 and 1 is called machine language.（3）C++ is an often considered to be a superset of C , but this is not strictly true.（4）Most C code can easily be made to compile（编译）correctly in C++. （5）C++ is an enhanced version of the C language.（6）Methods are similar to the functions of procedure-oriented （面向过程）programming.（7）An object is simply an instance（实例）of a class.（8）Polymorphism gives object the ability to represent to messages from routines when the object’s exact type is not known.（9）It is a computer program that translates a series of instructions written in one computer language into a resulting output in another computer language.（三）Unit5（1）The operating system is also responsible for keeping track of the activities in the computer system.（2）Real-time operating system are used to control machinery,（机械，机器）scientific instrument and industrial systems.（3） A multi-user operating system allows many different users to take advantage of one computer’s resources simultaneously.（4）The OS is a large program made up of many smaller programs.（5）The OS control how the CPU communicates with other hardware components.（硬件组件）（6）The OS also makes computer easier to operate by people who don’t understand programming languages.（7）Operating system are constantly being improved or upgraded as technology advance.（8）Windows is custom-made to run with Intel CPU and Intel-compatible CPUs，such as Pentium IV.（9）It is a common term for a computer fault that brings down a software program or operating system .It is also refer to the failure of a hard disk drive.(三)Uint6（1）A data structure is a specialized format （格式，板式）for organizing and storing data.（2）Data structure organize data in ways that make Algorithms （算法）moreefficient.（3）An object-oriented approach to data structures （数据结构）brings together both data abstraction and procedural abstraction.（4）Once problem are Abstracted ,（抽象的）it becomes apparent that seemingly different problems are essentially similar or even equivalent in a deep sense.（5）Abstraction allows Common solutions to seemingly different problems.（6）Integer is amounts to a particular collection of anxious or rules that must be obeyed.（7）When a call is made to Algorithms, (算法)all the variable local to the callingroutine need to be saved by the system , otherwise the new function will overwrite the calling routine’s variables.（8）Computers in which the disk is attached to one machine, known as the file server.（文件服务器）Uint7（1）A database consists of a file or a set of files.（2）Fields are the basic units of data storage .（数据存储）（3）The external level defines the different views of the database as required by the external or user programs.（4）One user program may not require all the data in the database.（5）The conceptual level describe the entire database.（6）Object-based logical models are used for describing data at the conceptual （概念上的）and viewlevels.（7）For relationships involving two entity （实体）sets, there can be relationships like one-to-one，one-to-many, many-to-one，and many-to-many.（8）There are various data types to choose from, such as character，numeric ,data ,or other.Unit8（1）A compiler（编译器）is a computer program that translates a computer programwritten in one computer language into an equivalent program.（2）Translation from a low level language to a high level one is also possible. （3）Compiles also exit which translate to a another.（4）Cross compilers are useful when bringing up a new hardware platform for the first time.（5）Since the intermediate level code （中级水平代码）is machine-like in character，but not in form ,it will normally vary with the machine for which the object code is being generated.（6）Intermediate code can be converted directly into the object language （目标语言）by the code generate.（7）Obviously code generation is highly machine-dependent.（8）When the object machine is altered ，the code generator（编译发生器）must be extensively revised.三、阅读理解（10题*2分）四、完形填空五、翻译（第七章重点考）。
