第1题
English has never been the only language in use over the British Isles , and it certainly is not now! Welsh is still used in Wales. Some Welsh people still speak it as their mother tongue , and it is widely taught in Welsh schools. Some people in Scotland and in Ireland still use a language that is related to Welsh. It is called Gaelic. These languages have a long history in these islands - longer than the history of English. In addition , people from
overseas have settled in England quite recently during this century. In some industrial cities , though not generally in Britain , you find groups of people who speak Polish , and other groups speaking the languages of the Indian subcontinent. A survey of North London schools in the early 1980' s found that nearly a third of the children spoke a language other than English at home.
The majority of the 55 million people living in England use English all the time. Standard English , that is , written English , is in use throughout Britain. Spoken English , however , sounds very different in different parts of the country. There is a story , a play. by the famous writer George Bernard Shaw , about a professor of English Language who can tell you someone' s address when he hears that person speak! That is exaggeration of course. Not even a Professor , who has studied the sounds of English all his life , can really do that. However ,it is true hat most people who have lived for a long time in Britain can tell a number of things about the people as soon as they speak! Usually we cannot tell the speaker' s address
, but we can guess the part of the country where the person comes from. We can tell how well educated he or she is too! If an international user of English , like anyone of you here , happens to meet speakers from , say , the North or the West of England , you may find them hard to understand. Unless you understand what is going on your confidence in your ability to use the language may be badly shaken.

ing while
their action says another？ A facial expression, crossed arms or the way they behave can show what
is really in their mind. This is body language, and we must teach our children to understand and
use it.
We often teach children to be thoughtful when they speak and write, and we also need to teach
them to be thoughtful in their body language. Giving examples is one of the ways to do that. Help
children understand that people use body language most of the time in their life. Where they're
looking when they speak, how they turn their bodies, how they place their arms and so on can give
others important information.
There will be times that people want and need to use their body language. In school or job
situations, understanding body language can make a difference. And using body language in other
situations is also helpful to personal safety and sometimes stops misunderstandings(误会).

Assembly Language
汇编语言
Introducing Assembly Language
Assembly language unlocks the secrets of your computer's hardware and software[1]. It teaches you about the way the computer's hardware and operating system work together and how application programs communicate with the operating system.
To understand a computer and it.s operating system fully, one needs to study software at various levels. One is the application program level, where such programs interact with DOS. Another is the high-level language level, where powerful statements are expanded into many machine instructions recognized directly by CPU (Central Processing Unit), as well as the way programs communicate with DOS.
What Is Assembly Language？
Assembly language is a programming language with a one-to-one correspondence between its statements and a computer's machine language. There is no single assembly language because there is no single type of computer CPU. Each assembly language is directly influenced by a computer's machine instruction set and hardware architecture.
Strictly speaking, IBM-PC assembly language refers to instructions recognized by the intel 8086-80486(CPU) microprocessor family. But there is such close interaction between the CPU, computer peripherals, the DOS operating system, and the macro assembler itself that our discussions will often include all these topics.
What Is An Assembler？
An assembler is a program that converts source-code programs into machine language. In this passage, we will refer to an assembler that generates machine instructions for IBM- compatible microcomputers. All such computers use the Intel family of microprocessors, beginning with the Intel 8088, through the Intel 80486 (and beyond). Our programs will run under the PC-DOS/MS-DOS operating system, version 3. 0 or later. The two best- known assemblers for the IBM-PC are MASM (Microsoft Assembler) and TASM (Borland Turbo Assembler).
Assembly language is a specific set of instructions for a particular computer system. It provides a direct correspondence between symbolic statements and machine language. An assembler is a program that translates a program written in assembly language into machine language, which may in turn be executed by the computer. Each type of computer has a different assembly language, because the computer's design influences the instructions it can execute.
Assembly language is called a low-level language because it is close to machine language in structure and function. We can say that each assembly language instruction corresponds to one machine instruction. In contrast, high-level languages such as Pascal[2], BASIC[3], FORTRAN[4], and COBOL[5]contain powerful statements that are translated into many machine instructions by a compiler.
Why Learn Assembly Language？
People learn assembly language for various reasons. The most obvious one may be to learn about the computer's architecture and operating system. You may want to learn more about the computer you work with and about the way languages generate machine code. Because of assembly language's close relationship to machine language, it is closely tied to the computer's hardware and software.
You may also want to learn assembly language for its utility. Certain types of programming are difficult or impossible to do in high-level language. For example, direct communication with the computer's operating system may be necessary. A high-speed color graphics program may have to be written using a minimum of memory space. A special program may be needed to interface a printer to a computer. Perhaps you will need to write a telecommunications program for the IBM-PＣ. Clearly, the list of assembly language applications is endless.
Often there is a need to remove restrictions. High-Ievel languages, out of necessity, impose rules about what is allowed in a program. For example, Pascal does not allow a character value to be assigned to an integer variable.[6] This makes good sense unless there is a specific need to do just that. An experienced programmer will find a way around this restriction or rule; nearly everything is left to the discretion of the programmer. The price for such freedom is the need to handle many details that would otherwise be taken care of by the programming language itself.
Assembly language's usefulness as a learning tool should not be underestimateＤ. By having such intimate contact with the operating system, assembly language programmers come to know instinctively is how the operating system works. This knowledge, coupled with knowledge of hardware and data storage, gives them a tremendous advantage when tackling unusual programming problems. They have a different viewpoint than programmers who know only high-level language.
Assembly Language Applications
At first, the assembly language programs presented later will seem almost trivial. Those new to assembly language often cannot believe the amount of work required to perform relatively simple tasks. The language requires a great deal of attention to detail. Most programmers don't write large application programs in assembly language. Instead, they write short, specific routines.
Often we write subroutines in assembly language and call them from high-level language programs. You can take advantage of the strengths of the high-level languages by using them to write applications. Then you can write assembly language subroutines to handle operations that are not available in the high-level language.
Suppose you are writing a business application program in COBOL for the IBM-PＣ. You then discover that you need to check the free space on the disk, create a subdirectory, write a file, and create overlapping windows, all from within the program. Assuming that your COBOL compiler does not do all this, you can then write assembly language subroutines to handle these tasks.
Let's use another example: you might have written a word processing program in C[7]or Pascal, but it performs slowly when.updating the screen display. If you knew how, you could write routines in assembly language to speed up critical parts of the application and allow the program to perform up to professional standards.
Large application programs written purely in assembly language, however, are beyond the scope of the person who has just finished this book. There are many people who write complete assembly language application program for the IBM-PＣ. The few programmers in this group are familiar with several machine architectures and assemblers, and have been programming professionally for at least several years. These fortunate individuals still had to start with a basic foundation, and this book is intended to help you acquire just that.
Above all, assembly language programmers must know their date, for without a detailed understanding of how each date type is stored(at the bit level) , one might make serious mistakes. High-Ievel programming languages intentionally shield programmers from implementation-specific details, in the name of convenience and source-code portability. Assembly language, in contrast, is highly machine-specific and imposes few, if any, restrictions.
Machine Language
Before we embark on a rather long and detailed study of assembly language, let's put it into perspective. A computer doesn't actually understand assembly language-it understands machine language. Machine language is a language made up of numbers, which can be interpreted by a computer's CPU. A CPU usually has a small program embedded directly in the chip, called microcode. The microcode interpreter translates machine instructions directly into hardware signals.
Machine language makes it possible for the CPU to perform ordinary tasks, such as moving numbers or performing arithmetiＣ. Each CPU has its own machine language; or, in the case of IBM-compatible computers, all CPUs that belong to the intel family (8088, 8086,80186,80286,80386,80486) share a common machine language. This is an example of a machine language instruction that moves 5 into the AL register: 10110000 00000101. The number is written in binary, a number system made up of only the digits 1 and 0. The first 8 bits are the operation code (op code), which identifies it as the instruction that moves an 8-bit number to the AL register. The second 8 bits are the operand[8]. The complete instruction moves the number 5 to a register called AL. Registers are high-speed storage locations inside the CPU. They are identified by two-letter names, such as AH, AL, or AX.
A CPU's instructions set is the set of machine instruciions that the CPU is able to execute. For the Intel CPU family, the instruction set is downward-compatible, meaning that an instruction that works on a lower-level processor will always work on a higher-level processor. For example, the MOV instruction[9]works on the 8088, and therefore must work on the 80286. But there are many advanced instructions for the 80286 that do not work on the 8088.
At one time, all programs were written in machine language. But it's easy to see that machine instructions are difficult for humans to read and write. This is why assemblers and compilers were created, which would convert more readable instructions, created by a text editor, into machine language. Instead of writing the machine instruction shown earlier, we would write the following in assembly language:
M o v ah, 5

第11题
If you look at a map of Europe, you'll see a group of islands--one larger island off the northwest coats, one smaller and many tiny ones. These make up what is called the British Isles (不列填群岛). The largest island of the British Isles in Britain. It is also called Great Britain. The smaller island is Ireland (爱尔兰)。
Britain is divided into three parts: Scotland, Wales and England. But sometimes the word " England" is used instead of "Britain". Why so？
In anceient times, what is Britain now used to be three different countries. People in these different counntries spoke different languages. Over many years the three countries became one. England in the largest and richest of the three and it has the most people. So the English people take it for granted that their own name stands for the whole island.
There's another thing that confuses people; sometimes you may hear people say "the United Kingdom of Great Britain and Northern Ireland. "That is the official name of the country. Northern Irelnd is only one sixth of the island of Ireland. The rest of the island is an independent state, called the Republic of Ireland. So we have the names of "England", "Britain"," Great Britain", and "the United Kingdom of Great Britain and Northern Ireland". Now do you know what each of them means？
English was first spoken in ______.
A．Britain
B．England
C．Great Britain
D．Ireland
