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.
36. Gaelic is related to Welsh. ()
37. Welsh is not taught in schools anymore. ()
38. One third of the 55 million people in England speak other languages besides English at home ()
39. Written English is in use throughout Britain but spoken English sounds different in different parts of the country. ()

When faced with the decision of selecting a mode of transportation, the exporter has five basic types available from which to choose, depending, of course, upon the geographicalproximity[1] of the countries of export and import: ocean, air, rail, truck, and inland water. A sixth alternative is pipeline which transports very specialized products. The choice between available methods of transportation is usually determined by a combination of cost , time , and security.
Ocean transportation is by far the most dominant mode of international transportation , and air transport is the most " glamorous" and fastest growing. The significance of the other basic types of international transportation varies depending upon the countries involved. For example,rail and truck shipments do not constitute a significant portion of the export transactions of the United States, except perhaps for those that involve buyers in Canada. In contrast,these transport modes carry large amounts of export goods among the countries of Europe. Similarly,inland waterways are not important carriers of goods between countries except in Europe where waterways such as the Rhine and Danube rivers carry large amounts of goods among the countries through which they flow. Often the use of these relatively less important modes of transport depends upon the nature of specific products in unique geographic situations. The use of trucks to haul fresh produce from northem Mexico to the United States illustrates this practice.
Ocean transportation is widely used because it is a relatively low-cost way to transport goods, and it can easily handle large shipments. In addition, certain geographic conditions may make it impossible to use overland transportation to some foreign markets andinfeasible[2] to use it to others.
Many diverse types of products are being transported to foreign markets by air in large volume-computers, office machines, electrical and electronic equipment, automobile parts, television sets,pharmceuticals[3], certain metal manufactures, and wearing apparel to name but a few. Thus , even with existing technology, it is evident that air cargo movements are no longer confined to fast shipments of emergency supplies, goods of high value , (for example ,jewel) and perishable products (for example , fresh flowers) , although it is widely used for such products. Not only is time in transit reduced from a minimum of 10 days to a few hours, but also less handling and simpler packing requirements are involved.
Time in transit is but one of the so-called hidden costs that may be relevant. For example,concerning time in transit and the ability to put a f'acility to use sooner (thus avoiding lost sales) ,a West German company bought 230hosiery-knitting machines[4] from a US manufacturer. The machines were shipped by air at a cost of USD 224 per unit which was considerably greater than the ocean rate of USD37. 80 per unit. Delivery time was shortened by 10 days giving the Cerman manuf'acturer the opportunity to produce 207 000 pairs of hosiery, which apparently offset the transportation cost.
Small shipments may be sent by intemational parcel post, air parcel post, or air couner service rather than pay the higher minimum bill of lading charges for ocean freight or air shipment. While larger shipments are charged on the basis of weight or measurement,very small shipments are charged a set flat fee because of the costs involved in documentation and handling.
The method of transportation is usually selected by the importer. The route selected for the export shipment may be determined by either the exporter or the importer. In practice , the importer should indicate the route he or she thinks is most desirable. The final selection of the exact route,however,should generally be left to thediscretion[5] of the exporter, since the exporter is more fully acquainted with conditions surrounding the shipment in the country from which it is sent, and particularly the immediate conditions at time of shipment.

Computer Languages
计算机语言
A computer must be given instructions in a language that it understands, that is, a particular pattern of binary digital information. On the earliest computers, programming was a difficult, laborious task, because vacuum tube ON/OFF switches had to be set by hand. Teams of programmers often took days to program simple tasks, such as sorting a list of names. Since that time a number of computer languages have been devised, some with particular kinds of functioning in mind and others aimed more at ease of use-the user-friendly approach.
Machine Language
Unfortunately, the computer's own binary based language, or machine language, is difficult for humans to use. The programmer must input every command and all data in binary form, and a basic operation such as comparing the contents of a register to the data in a memory chip location might look like this: 11001010 00010111 11110101 00101011. Machine language programming is such a tedious, time-consuming task that the time saved in running the program rarely justifies the days or weeks needed to write the program.
Assembly Language
One method programmers devised to shorten and simplify the process is called assembly language programming. By assigning a short (usually three letter) mnemonic code to each machine language command, assembly language programs could be written and-debugged-cleaned of logic and date errors-in a fraction of the time needed by machine language programmers. In assembly language, each mnemonic command and its symbolic operands equals one machine instruction. An assembler program translates the mnemonic opcodes (operation codes) and symbolic operands into binary language and executes the program. Assembly language is a type of low level computer programming language in which each statement corresponds directly to a single machine instruction. Assembly languages are, thus, specific to a given processor. After writing an assembly language program, the programmer must use the assembler language into machine code. Assembly language provides precise control of the computer, but assembly language programs written for one type of computer must be rewritten to operate on another type. Assembly language might be used instead of a high levcl language for any of three major reasons: speed, control, and preference. Programs written in assembly language usually run faster than those generated by a compiler; use of assembly language lets a programmer interact directly with the hardware (processor, memory, display, and input/output ports). Assembly language, however, can be used only with one type of CPU chip or microprocessor. Programmers who expended much time and effort to learn how to program one computer had to learn a new programming style each time they worked on another machine. What was needed was a shorthand method by which one symbolic statement could represent a sequence of many machine language instructions, and a way that would allow the same program to run on several types of machines. These needs led to the development of so-called high level languages.
High Level Languages
High level languages often use English-Iike words-for example, LIST, PRINT, OPEN, and so on-as commands that might stand for a sequence of tens or hundreds of machine language instructions. The commands are entered from the keyboard or from a program in memory or in a storage device, and they are interpreted by a program that translates them into machine language instructions.
Translator programs are of two kinds: interpreters and compilers. With an interpreter, programs that loop back to reexecute part of their instructions reinterpret the same instructions each time it appears, so interpreted programs run much more slowly than machine language programs. Compilers, by contrast, translate an entire program into machine language prior to execution, so such programs run as rapidly as though they were written directly in machine language.
American computer scientist Grace Hopper is credited with implementing the first commercially oriented computer language. After programming an experimental computer at Harvard University[1], she worked on the UNIVAC[2]I and II computers and developed a commercially usable high level programming language called FLOW MATIC to facilitate computer use in scientific applications. IBM[3]then developed a language that would simplify work involving complicated mathematical formulas. Begun in 1954 and completed in 1957, FORTRAN (FORmula TRANslator)[4]was the first comprehensive high level programming language that was widely used. In 1957, the Association for Computing Machinery[5]set out to develop a universal language that would correct some of FORTRAN' s perceived faults. A year later, they released ALGOL[6](ALGOrithmic Language), another scientifically oriented language; widely used in Europe in the 1960s and 1970s, it has since been superseded by newer languages, while FORTRAN continues to be used because of the huge investment in existing programs. COBOL[7](COmmon Business Oriented Language), a commercial and business programming language, concentrates on data organization and file handling and is widely used today in business.
BASIC[8](Beginners All-purpose Symbolic Instruction Code) was developed at Dartmouth College in the early 1960s for use by nonprofessional computer users. The language came into almost universal use with the microcomputer explosion of the 1970s and 1980s. Condemned as slow, inefficient, and inelegant by its detractors, BASIC is nevertheless simple to learn and easy to use. Because many early microcomputers were sold with BASIC built into the hardware (in ROM memory) the language rapidly came into widespread use. As a very simple example of a BASIC program, consider the addition of the numbers 1 and 2, and the display of the result. This is written as follows (the numerals 10-40 are line numbers):
10 A=1
20 B=2
30 C=A+B
40 PRINT C
Although hundreds of different computer languages and variants exist, several others deserve mention. PASCAL[9], originally designed as a teaching tool, is now one of the most popular microcomputer languages. LOGO was developed to introduce children to computers. C, a language Bell Laboratories designed in the 1970s, is widely used in developing systems programs, such as language translators. LISP[10]and PROLOG are widely used in artificial intelligence.
COBOL
COBOL, in computer science, acronym for COmmon Business-oriented language, is a verbose, English-like programming language developed between 1959 and 1961. Its establishment as a required language by the U. S. Department of Defense, its emphasis on data structures. and its English-like syntax (compared to those of FORTRAN and ALGOL) led to its widespread acceptance and usage, especially in business applications. Programs written in COBOL, which is a compiled language, are split into four divisions: Identification, Environment, Data, and Procedure. The Identification division specifies the name of the program and contains any other documentation the programmer wants to add. The Environment division specifies the computer(s) being used and the files used in the program for input and output. The Data division describes the data used in the program. The Procedure division contains the procedures that dictate the actions of the program.
C & C++
A widely used programming language, C was developed by Dennis Ritchie at Bell Laboratories in 1972; it was so named because its immediate predecessor was the B programming language. Although C is considered by many to be more a machine independent assembly language than a high level language, its close association with the UNIX[11]operating system, its enormous popularity, and its standardization by the American National Standards Institute (ANSl)[12]have made it perhaps the closest thing to a standard programming language in the microcomputer/workstation marketplace. C is a compiled language that contains a small set of built in functions that are machine dependent. The rest of the C functions are machine independent and are contained in libraries that can be accessed from C programs. C programs are composed of one or more functions defined by the programmer; thus, C is a structured programming language. C+ +, in computer science, is an object oriented version of the C programming language, developed by Bjarne Stroustrup in the early 1980s at Bell Laboratories and adopted by a number of vendors, including Apple Computer, Sun Microsystems, Borland International, and Microsoft Corporation.

Slang , informal, nonstandard words and phrases , generally have shorter lives than the expressions of ordinary colloquial speech. The former are typically formed by creative , often witty juxtapositions of words or images. Slang can be contrasted with jargon (technical language of occupational or other groups) and with argot or cant (secret vocabulary of underworld groups) , but the borderlines separating these categories from slang are extremely blurred , and some writers use the terms cant , argot , and jargon in a general way to include all the foregoing meanings.
Slang trends originate in subcultures within a society. Occupational groups (for example , loggers , police , medical professionals , and computer specialists) are prominent originators of both jargon and slang. Other groups creating slang include the armed forces , teenagers , racial minorities , ghetto residents , labor unions , citizen-band radiobroadcasters , sports groups , drug addicts , criminals , and even religious denominations (Episcopalians , for example , produced the term ‘spike' , meaning a High Church Anglican). Slang expressions
often embody attitudes and values of group members. They may thus contribute to a sense of group identity and may convey to the, listener information about the speaker' s background. Before an apt expression becomes slang , however , it must be widely adopted by members of the subculture. At this point slang and jargon overlap greatly. If the subculture has enough
contact with the mainstream culture , its figures of speech become slang expressions known to the whole of society. For example , cool cat (aloof , stylish person) , Mr. Charley (a white man) , The Man (the law) , and Uncle Tom (a meek black) all originated in the predominantly black Harlem district of New York City and have traveled far since their inception. Slang is thus generally not tied to any geographic region within a country.
A slang expression may suddenly become widely used and as quickly dated (skiddoo). It may become accepted as standard speech , either in its original slang meaning (bus , from omnibus) or with an altered , possibly tamed meaning (jazz , which originally had sexual connotations). Some expressions have persisted for centuries as slang (booze for alcoholic beverage). In the 20th century , mass media and rapid travel have sped up both the circulation and the demise of slang terms. Television and novels have turned criminal cant into slang (five grand for $5000). Changing social circumstances may stimulate the spread of slang. Drug-related expressions (such as pot and marijuana) were virtually a secret jargon in the 1940s; in the 1960s they were adopted by rebe11ious youth; and in the 1970s and '80s they were widely known.

Does this sound familiar？ You have probably read something like it in magazines or books, or seen it in a film. Why is it so popular？ One of the reasons is that it reflects the fears of many people; fear of the unknown fear of what is not understood or, at least, fear of something that is not completely understood.
The fact is that every day it seems that computers take control of another area of our lives. Some
factory jobs are now done by robots and the robots are controlled by computers. Our bank accounts are managed by computers. At the airport, our tickets are sold by a computer. Certainly, many of these operations are made more
efficient by computers, but our admiration is sometimes mixed with unsafe feelings. And this lack of safety is caused by the fact that we do not know how computers do these things, and we really don't know what they might do next. But we can find out how computers work, and once we understand them, we can use computers instead of worrying about being used by them. Today, there is a new generation of computer wizards who know exactly how computers get things done. These young men and women, usually university students, are happy to sit for hours, sometimes for days, designing programs, not eating, not sleeping, but discovering what can be done by these wonderful slaves which they have learned to control. These computer wizards have learned to use the computer and search for new tasks for their machines.
(1)、According to the passage, our present world is under the control of ______ .
A：mad scientists
B：men and women
C：the unknown fear
D：some super-inventions
(2)、The reason why many people are afraid of computers is that ______ .
A：they don't know anything about computers
B：they haven't really understood computers
C：there are so many computer games
D：computers are often down
(3)、The author mentions computer wizards in order to point out that ______ .
A：computers can be controlled by man
B：there should be more people devoted to computers
C：only young people are interested in computers
D：more time and energy is required to control computers
(4)、This passage is probably written to suggest that ______ .
A：some day computers can deal with all human problems
B：computers can be used in place of traveling to our jobs
C：people should not fear computers
D：computer technology will not meet people's needs in various situations
(5)、The author's attitude towards widely used computers is __.
A：positive
B：anxious
C：worried
D：serious
Like most wars,a trade war may bring about desired economic or political changes, but in the long run almost everyone suffers ,including those whom the trade war was meant to help.
An efficient carmaker, for example, may ask for limits of foreign imports, hoping to keep its price high without improving the quality of its products. In the end , however , other countries may retaliate with trade restrictions of their own. Consumers and businesses in both countries are then forced to buy poorly made and expensive domestic products. Trade restrictions might protect a few jobs in inefficient industries,but the whole economy often suffers by becoming less competitive in the international markets.
The most common tools for limiting imports of foreign goods and services are quotas, tariffs,and subsidies. When a country imposes a quota, it limits the quantity of certain foreign products that can be imported. A tariff is a tax placed on goods entering a country , raising the price of imported goods. A government can also use the taxpayers' money to provide a subsidy to local producers , making the price of local goods artificially lower than imported goods.
Trade barriers, like walls between feuding neighbors, are usually imposed unilaterally by one country acting on its own to limit the amount of foreign products available to local producer from foreign competition and allow them time to improve their products or lower their prices as long as they are protected from foreign competition by trade barriers.
Although trade restrictions are of dubious economic value, they have been shown to be effective in bringing about political or social change. The refusal of countries to trade and do business with South Africa, for example, was widely seen to be responsible for the decision to dismantle the system of apartheid. Trade blockades can be useful in forcing countries to change policies that violate human rights or international treaties, but as long as a sufficient number of countries join in the blockade to make it effective.
