ple pay nothing, and the percentage of tax grows greater as the taxpayer's income grows.

But countries with direct taxation nearly always have indirect taxation, too. 4. Many things being imported into the country, customers have to pay taxes or "duties".Of course, it is the men and women who buy these imported things in the shops who really have to pay the duties, in the form of higher prices. In some countries, too, there is a tax on things sold in the shops.

If the most necessary things are taxed, a lot of money is collected, but the poor people suffer most. If unnecessary things like jewels and fur coats are taxed, less money is obtained, but the tax is fairer, as the rich pay it.

5. Probably this last kind of indirect tax, together with a direct tax on incomes which is low for the poor and high for the rich, is the best arrangement Tax system is a two-way street. The more taxes we pay, the more profitable our nation becomes.

WHAT IS A COMPUTER?

1.The word “computer” comes from a Latin word which means to count. A computer is known to be a very specific kind of counting machine. To do different problems fast without using a computer is extremely difficult. By means of electric circuits it can find the answer to a very difficult and complicated problem in a few seconds.

2.Initially, the computer was designed as a tool to manipulate number and thus solve arithmetic problems. At present it is applicable for a great variety of tasks. Nowadays computers are considered to be complicated machines for doing arithmetic and logic. The computer proved to have become an important and powerful tool for collecting, recording, analysing and distributing tremendous masses of information.

3.There are different kinds of computers. They may be general-purpose computers as well as special-purpose ones. Special-purpose computers do only one job over again. Each specific application requires a specific computer. A special-purpose computer is built to solve one problem. General-purpose computers are able to do many different jobs.

4. Any computer is, architecturally, like any other computer. Regardless of their size or purpose most computer systems consist of three basic elements: the input-output ports, the memory hierarchy and the central processing unit. The memory hierarchy stores both the instructions (the program) and the data in the system. The CPU controls the operation of the entire system by issuing commands to other parts of the system and by acting on the responses. When required it reads information from the memory, interprets instructions, performs operations on the data according to the instructions, writes the results back into the memory and moves information between memory levels or through the input-output ports.

THE COMPUTER REVOLUTION

1.Without the computer space programs would be impossible and the 21st century would be impossible. More than any other single invention, perhaps even more than wheel, the computer offers a dazzling promise and an awful threat that it seems to change the direction and meaning of our lives.

2.Computers today are known to run our factories, to plan our cities, to teach our children, to predict tomorrow’s weather, and even to play chess, to write poetry or compose music.

3.In the new age of exploration the computer is solving in milliseconds the problems a generation of mathematicians would need years to solve without its help. The small, fifty-nine-pound computer is said to do one billion different space-maneuvering, navigation, and re-rentry problems. Translating the answer into simple numbers it tells the astronaut the attitude to which he must bring the spacecraft.

4.To simulate one or a million variants of the same theme is one of the computer’s greatest assets. The computer can do far more than simulate the mechanics of space flight; it can furnish accurate models of life itself.

5.With computer simulation you can have a series of problems in which you can figure out all the ramifications, all the permutations and combinations, and do it very quickly. You can get a computer model of a city and play out all the different effects, for example, the effects on industry locations, residential densities, and the like.

What can we do with computer simulation ?
