Language is always changing. In a society where life continues year after year with few changes, the languages do not change either. The earliest known languages had difficult grammar but a small, limited vocabulary. Over the century, the grammar changed, and the vocabulary grew. For example, the English and Spanish people who came to America during the sixteenth century gave names to all the new plants and animals they found. In this way, hundreds of new words were introduced into English and Spanish vocabularies. Today life is changing very fast,and language is changing fast too.

There are several major language families in the world. Some scientists say there are nine main families, but other scientists divided them differently. The languages in each family are connected, and scientists think that they came from the same parent language. About 3% of the people in the world speak languages that are not in these major families.

1. The early language had many words and easy grammar.

A. T B. F

2. In the next few hundred years we can expect language to change a great deal.

第6题

For more than 600 years people have complained that youngsters cannot write proper English
anymore. Two universal truths emerge: languages are always changing, and older people always worry that the young are not taking proper care of the language. The problem is that conservatism works differently on writing than it does on speech. Writing is more permanent, so people choose their words carefully and conservatively. It is slow and considered, so people can avoid new usages widely seen as mistakes. It is taught carefully by adults to children, which naturally has some conservative influence on the written language. And it is often edited, so a young journalist with a casual style. may well be edited to a more traditional one by an older editor. Speech is different: instead of permanent, slow, considered and taught, it is impermanent, fast, and learned naturally by children from their surroundings. Speech will— at almost any level of language conservatism—change faster than written language. In this imperfect world, then, written language only partly reflects speech. Younger writers introduce spoken or new words or usages into their writing, annoying their elders as they do. But no one dare to be casual in spelling: English-speakers are stuck with an ancient system. Liberties with grammar—making the written language look like the spoken one— should be few and cautious. Giving the written language a little room to change, but not too much, is the only way to enjoy the best of both stability and vitality. The alternative— perfectly conservative writing—will make writing less and less like the language future generations will speak, and thus less relevant to writing about the world they live in.

It can be learned from Paragraph 1 that older people worry that______.

A.youngsters have too many complaints

B.spoken language is changing too fast

C.their English is not as good as before

D.youngsters are careless with language use

16.Read Passage 1 , and then answer Questions 16-20 briefly. Write your answers on the Answer Sheet.

Passage 1

Verbal skills in another culture can generally be mastered if one studies hard enough. But nonverbal skills are much more difficult to learn. Nonverbal behavior. includes areas such as eye contact , facial expressions , postures , gestures , and the use of time , space , and territory. The messages sent by body language and the way we arrange time and space have always been open to interpretation. Does a raised eyebrow mean that your boss doubts your statement or just that she is seriously considering it? Does a closed door to an office mean that your coworker is angry or just that he is working on a project that requires concentration? Deciphering nonverbal communication is difficult for people who are culturally similar , and it is even more troublesome when cultures differ.

In Western cultures , for example , people perceive silence as negative. It suggests rejection , unhappiness , depression , regret , embarrassment , or ignorance. However , the Japanese admire silence and consider it a key to success. A Japanese proverb says , "Those who know do not speak; those who speak do not know." Over 60 percent of Japanese businesswomen said that they would prefer to marry silent men. Silence is equated with wisdom.

16. According to the author , what does nonverbal communication include?

17. What is the main idea of Paragraph One?

18. "Those who know do not speak; those who speak do not know." What does this Japanese proverb imply?

19. Understanding body language within the same culture group is very easy , is it?

20. What does silence mean in Western cultures?

Assembly Language

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

Interviewer: Jane, you've recently returned from Japan. How long did you live there?

Jane: For five years.

Interviewer: And why did you go to Japan in the first 21?

Jane:Well, a Japanese exchange student was living with my family, and he got me interested in going to Japan. He encouraged me 一 22一 to get a teaching job there and even offered me a place to stay until I found an apartment—at his mother's house in Tokyo.

Interviewer: So you went?

Jane: I did. When I arrived his mother was very helpful, but she didn't speak much English and I didn't speak any 23 .We managed to communicate, somehow, with gestures and mime, or sometimes we would both use dictionaries.

Interviewer: In what ways is life in Japan —24— from life in the United States?

Jane:In just about every aspect. A big change was using public transportation in Tokyo instead of a car. Trains, subways, and other transportation in Japan are very good, though crowded. You get used 一 25一 more often, because, without a car, you have to carry your groceries home. But I was really glad to be rid of my car. Another thing is the low crime rate in Tokyo and other big cities in Japan. I always felt —26— and never worried about crime. That's pretty unusual in almost any big city in the world today.

Interviewer: Did you have any difficulties adjusting?

Jane: Well, at the beginning it was hard not knowing the language. At first I learned survival Japanese, so I could get by in everyday situations, but anything technical was difficult for me to understand. I took classes, but it was slow going, and I didn’t always express myself because I was afraid of —27— mistakes. I wish I had taken more risks一I would probably have learned the language faster. Another thing I had to get used to was living in a culture where the majority of people looked different from me. I knew I'd always be an —28— in some ways.

Interviewer: What about Japanese food?

Jane: Overall, the diet there is a healthy one-low fat. Oh, there were many Japanese specialties that I liked, and others that I didn't like so much. The food wag very different, but I didn't expect to eat American style. there. I expected to eat Japanese style. and though,—29— Japanese products. I think Japanese food preparation takes a long time and I didn't have a lot of time to prepare food, so much of my experience comes from eating in restaurants.

Interviewer: What advice would you give to someone going to live overseas for the first time?

Jane: Do some of the things I didn't do: Before you go, read as much as you can. Find out about the culture, the customs, the holidays, the traditions. Learn a little bit of the language if you can and the way people express politeness. Be flexible. Living in another culture is like seeing the world through a new pair of glasses—at first everything—30—confusing. But if you keep your eyes open,eventually everything becomes clear. Unfortunately, a lot of people just close their eyes.
