We know a computer is a machine that processes data(stored in main memory)into information, under control of a stored program. We also know that, internally, a computer is a binary machine; thus the data and the program instruictions must be stored in binary form. Characters are represented in(71). Numbers are stored as binary numbers, with each bit's positional value significant. A computer's main memory is divided into bytes, words or both(depending on the system), and each of these basic storage units is assigned an(72). Using this address, the processor can read or write selected bytes or words.

The processor consists of a clock, an instruction control unit, an arithmetic and logic unit, and registers. Once a program is stored in main memory, the processor can begin to execute it. During(73), the instruction control unit fetches an instruction from main memory; during(74), the arithmetic and logic unit executes it. Precisely timed electronic pulses generated by the clock drive this basic(75)

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.

Your title should reflect the thesis or central argument of your essay. Avoid repeating the topic as assigned(or selected).

Begin with a statement about the general topic and proceed to your particular thesis(论文) and approach to it. This structure will orient(使确定方向) your reader. Avoid giving a summary of what is to follow. Avoid writing about your essay; write only about your subject.(In other words, avoid such statements as: "In this section I shall discuss x" Simply discuss x.)

The middle section of the essay should be divided into carefully connected paragraphs, each consisting of four to eight sentences. Avoid overly long or short paragraphs. Each paragraph should contain one major point, and must be related logically and grammatically to the preceding and following ones. Use connecting words(such as: however, therefore, in addition, nevertheless, and so on) to ensure smooth and clear transitions(过渡) between points and paragraphs. Never apologize. Avoid too such statements as "in my opinion", since the entire essay is assumed to be your opinion—that is, an opinion based upon and supported by material from the texts.

Since the argument has built up to your strongest point, your conclusion should begin with what your argument proved—your thesis. A brief and reworded summary of your main points could follow for emphasis, but a plodding(单调乏味的) repetition should be avoided. End with an "opening outwards" to the general implications of your findings, remembering that the reader should be left with a feeling of your conviction, not your doubt or hesitation.

In the opening paragraph, you should avoid ______.

A．orienting your reader

B．discussing x

C．writing only about your subject

D．writing about your essay

These two main divisions are cultural anthropology and physical anthropology. Culture includes many things, such as art, religion, laws, and even furniture and movies.
