Mastery of the English language? Many people think that just by attending a two or three-week course, they can become experts in the language. This is usually not the case. Those who are really good at the language have studied it for years, even decades. They read a lot and they learn everything they can about the language including the meanings of its words, its sentence structures and correct usage. Only after many grueling years of serious study have they become as good as they are. A great percentage of the success of such people depends on hard work not only just dreaming day and night…..
My first rigorous efforts in improving English listening, writing, reading and speaking skills is reading a lot of reading materials such as news paper, magazines, articles and others. By reading more, I can improve more in my vocabulary and indirectly I can get a new word power which I can apply in my English essay writing. By reading news paper, I not only get the latest news but on the same time I can improve my writing skill also. That is why I love to read news paper every day..
Listening to other people speaking can improve my listening and also speaking skills. When I listened to my friends spoke, I will try to catch up what they wanted to say. Besides, I also love to watch English movie. By watching the movie I can get new word while enjoying the movie..
In my pocket, I always bring along my small note book. If I know a new word, without wasting any time, I will take that small note book and jot down the word. If I do not know the meaning of the word, I will find it in the dictionary and copy the meaning. Then, I try to make a sentence to make me more understand the word and how to use the word correctly in my essay.
In my opinion, English language is the most beautiful I the universe.. When used in writing such as poetry, essays and literature, its incomparable beauty clearly shines through.. The language can describe events, scenes, people, moods, etc. so precisely that crystal-clear pictures are formed in the minds of readers or listeners.
With the beauty and other superior qualities of the English language,it is very easy to fall in love with it. And because of that, I will try my best to master this language by improving my weaknesses..

SATELLITE
A satellite, in today's world has many different applications in many fields. Although before artificial satellites were invented a satellite was known as the moon or other planets. The moon is a satellite of the earth, it orbits around the earth due to the gravitational forces of the bodies. However, today when people hear the word satellite they thing of man made objects orbiting around the earth. Which is true and in the rest of my paper I will tell you exactly what a satellite is.
What is a satellite ?
An artificial satellite is a man made object placed into orbit around the Earth for the purpose of scientific research, weather reports, or military reconnaissance. Scientific satellites are set into orbit to observe the space environment, the Earth, the Sun, stars and extra galactic objects. These satellites have retrieved a huge amount of information helpful to scientific research. Weather satellites are used every day for meteorological forecasts and in shipping. Also military satellites play a important role in today's modern military. Satellites are extremely important today. All artificial satellites have certain features in common. They all include radar systems, sensors like optical devices in observation satellites and receivers and transmitters in communication satellites. Solar cells are used to generate power for the satellites and in some cases ,nuclear power is used. All satellites need altitude-control equipment to keep the satellite in the desired orbit.( Grolier Encyclopedia). All this information should answer the question what is a satellite

The orbit of the satellite is achieved when it is given a horizontal velocity of 17,500 mph at sea level causing the Earth's surface to curve away and as fast as it curves away gravity pulls the object downward and at this point the satellite achieved orbit. As the altitude of the satellite increases, its velocity decreases and its period increases. The period of satellite is the time the satellite takes to make on revolution around the Earth. Satellites in later orbit are called synchronous satellites. If the satellite orbits in a equatorial plane, it is called geostationary which means it is always over the same place on earth at all times. This form of orbit is used in weather for reports of a certain area at all times.( Grolier Encyclopedia ) The orbit of a satellite is very scientific but not hard to understand.
Repairing a Satellite
Most people would think how can you repair a satellite when you are on earth at it is in orbit above you in space. the only possible way to repair satellites is to go into space and get them. That seems like a hard task almost impossible although it is hard today it is capable by space shuttle. The astronauts have to grab hold of the satellite by the arm in the shuttle then lock down the satellite in the shuttle's payload pay. The next step in the process would be to make a series of space walks by the astronauts to repair or in some cases replace malfunctioning systems.

The conclusion is this should have supplied you with information about the functions of a satellite. Which includes, the different orbits of a satellite and the results of a dead satellite. Also the difficulty of repairing a damage satellite. Almost every field is enhanced by the use of artificial satellites. Satellites have help improve our technology a great deal.

managing pressure
For many people, being part of the business world comes at a substantial personal cost: stress. “It’s a high stress job,” people often say, as if this testifies to the position’s prestige. For people whose ability to cope is at crisis point, however, stress is no longer a matter of bravado. For them, stress is a serious problem that can have far-reaching consequences. To avoid reaching this point, stress must be managed.
Know the Symptoms of Stress
It is important to be able to distinguish between pressure and stress. Pressure is motivating, stimulating, and energizing. But when pressure exceeds our ability to cope, stress is produced. Sustained high levels of stress can, at worst, result in illness, depression, or even nervous breakdown. However, there are a number of warning signs that can help you determine when your level of stress is bordering on dangerous.
Take a good look at your well-being. If you experience some of the following behavioral and physical symptoms on a frequent or near-constant basis, it can indicate that you have crossed the line between healthy pressure and harmful stress.
Behavioral symptoms
Constant irritability with people
Difficulty in making decisions
Loss of sense of humor
Suppressed anger
Difficulty concentrating
Inability to finish one task before rushing into another
Feeling the target of other people’s animosity
Feeling unable to cope
Physical symptoms
Lack of appetite
Craving for food when under pressure
Frequent indigestion or heartburn
Constipation or diarrhea
Insomnia
Tendency to sweat for no good reason
Nervous twitches or nail biting
Headaches
Cramps and muscle spasms

The visual arts are art forms that focus on the creation of works which are primarily visual in nature, such as painting, photography, printmaking, and filmmaking. Those that involve three-dimensional objects, such as sculpture and architecture, are called plastic arts. Many artistic disciplines (performing arts, language arts, and culinary arts) involve aspects of the visual arts as well as other types, so these definitions are not strict.
The current usage of the term "visual arts" includes fine arts as well as crafts, but this was not always the case. Before the Arts and Crafts movement in Britain and elsewhere at the turn of the 20th century, "visual artist" referred to a person working in the fine arts (such as painting, sculpture, or printmaking) and not the handicraft, craft, or applied art disciplines. The distinction was emphasized by artists of the Arts and Crafts movement who valued vernacular art forms as much as high forms. The movement contrasted with modernists who sought to withhold the high arts from the masses by keeping them esoteric Art schools made a distinction between the fine arts and the crafts in such a way that a craftsperson could not be considered a practitioner of art

DRAWING
Drawing is a means of making an image, using any of a wide variety of tools and techniques. It generally involves making marks on a surface by applying pressure from a tool, or moving a tool across a surface. Common tools are graphite pencils, pen and ink, inked brushes, wax colo pencils, crayons, charcoals, pastels, and markers. Digital tools which simulate the effects of these are also used. The main techniques used in drawing are: line drawing, hatching, crosshatching, random hatching, scribbling, stippling, and blending. An artist who excels in drawing is referred to as a draftsman
PRINTMAKING
Printmaking is creating for artistic purposes an image on a matrix which is then transferred to a two-dimensional (flat) surface by means of ink (or another form of pigmentation). Except in the case of a monotype, the same matrix can be used to produce many examples of the print. Historically, the major techniques (also called mediums) involved are woodcut, line engraving, etching, lithography, and screenprinting (serigraphy, silkscreening) but there are many others, including modern digital techniques. Normally the surface upon which the print is printed is paper, but there are exceptions, from cloth and vellum to modern materials. Prints in the Western tradition produced before about 1830 are known as old master prints. There are other major printmaking traditions, especially that of Japan .
PHOTOGRAPHY
Photograph is the process of making pictures by means of the action of light. Light patterns reflected or emitted from objects are recorded onto a sensitive medium or storage chip through a timed exposure. The process is done through mechanical, chemical or digital devices known as cameras.
The word comes from the Greek words φως phos ("light"), and γραφις graphis ("stylus", "paintbrush") or γραφη graphê, together meaning "drawing with light" or "representation by means of lines" or "drawing." Traditionally, the product of photography has been called a photograph. The term photo is an abbreviation; many people also call them pictures. In digital photography, the term image has begun to replace photograph

A camera is a device used to capture images, as still photographs or as sequences of moving images. The term as well as the modern-day camera evolved from the camera obscura, Latin for "dark chamber", an early mechanism for projecting images, in which an entire room functioned as a real-time imaging system. The camera obscura was first invented by the Iraqi scientist Alhazen and described in his Book of Optics (1011-1021).[1English scientists Robert Boyle and Robert Hooke later invented a portable camera obscura in 1665-1666.
Cameras may work with the light of the visible spectrum or with other portions of the electromagnetic spectrum. A camera generally consists of some kind of enclosed hollow, with an opening or aperture at one end for light to enter, and a recording or viewing surface for capturing the light at the other end. Most cameras have a lens positioned in front of the camera's opening to gather the incoming light and to focus the image, or part of the image, on the recording surface. The diameter of the aperture is often controlled by a diaphragm mechanism, but some cameras have a fixed-size aperture.
Traditional cameras capture light onto photographic film or photographic plate. Video and digital cameras use electronics, usually a charge coupled device (CCD) or sometimes a CMOS sensor to capture images which can be transferred or stored in tape or computer memory inside the camera for later playback or processing.
Cameras that capture many images in sequence are known as movie cameras or as ciné cameras in Europe; those designed for single images are still cameras. However these categories overlap, as still cameras are often used to capture moving images in special effects work and modern digital cameras are often able to trivially switch between still and motion recording modes. A video camera is a category of movie camera which captures images electronically (either using analogue or digital technology).
Stereo camera can take photographs that appear "three-dimensional" by taking two different photographs which are combined to create the illusion of depth in the composite image. Stereo cameras for making 3D prints or slides have two lenses side by side. Stereo cameras for making lenticular prints have 3, 4, 5, or even more lenses. Some film cameras feature date imprinting devices that can print a date on the negative itself.
what is film????~~
Film is a term that encompasses individual motion pictures, the field of film as an art form, and the motion picture industry. Films are produced by recording images from the world with cameras, or by creating images using animation techniques or special effects.
Films are cultural artifacts created by specific cultures, which reflect those cultures, and, in turn, affect them. Film is considered to be an important art form, a source of popular entertainment, and a powerful method for educating -or indoctrinating- citizens. The visual elements of cinema give motion pictures a universal power of communication; some movies have become popular worldwide attractions, by using dubbing or subtitles that translate the dialogue.
Traditional films are made up of a series of individual images called frames. When these images are shown rapidly in succession, a viewer has the illusion that motion is occurring. The viewer cannot see the flickering between frames due to an effect known as persistence of vision — whereby the eye retains a visual image for a fraction of a second after the source has been removed. Viewers perceive motion due to a psychological effect called beta movement.
The origin of the name "film" comes from the fact that photographic film (also called film stock) has historically been the primary medium for recording and displaying motion pictures. Many other terms exist for an individual motion picture, including picture, picture show, photo-play, flick, and most commonly, movie. Additional terms for the field in general include the big screen, the silver screen, the cinema, and the movie
ANIMATION..
Animation is the technique in which each frame of a film is produced individually, whether generated as a computer graphic, or by photographing a drawn image, or by repeatedly making small changes to a model unit (see claymation and stop motion), and then photographing the result with a special animation camera. When the frames are strung together and the resulting film is viewed at a speed of 16 or more frames per second, there is an illusion of continuous movement. Generating such a film is very labour intensive and tedious, though the development of computer animation has greatly sped up the process.
Because animation is very time-consuming and often very expensive to produce, the majority of animation for TV and movies comes from professional animation studios. However, the field of independent animation has existed at least since the 1950s, with animation being produced by independent studios (and sometimes by a single person). Several independent animation producers have gone on to enter the professional animation industry.
Limited animation is a way of increasing production and decreasing costs of animation by using "short cuts" in the animation process. This method was pioneered by UPA and popularized by Hanna-Barbera, and adapted by other studios as cartoons moved from movie theaters to television.
Although most animation studios are now using digital technologies in their productions, there is a specific style of animation that depends on film. Cameraless animation, made famous by moviemakers like Norman McLaren, Len Lye and Stan Brakhage, is painted and drawn directly onto pieces of film, and then run through a projector.
