IV. Read the following passage and choose the correct answer to each of the questions below.

   There are different ways to keep fit. One of the most important ways is by exercising. Exercising must be done regularly. The amount of exercise done each time is dependent on the free time that a person has. Exercises can be done from twenty minutes to an hour. Sometimes, daily five-minute exercises are just as effective.

   Exercising can take place both indoors and outdoors. Those who exercise indoors often do so in the comfort of gymnasiums. They train on equipment that has been specially designed for the different parts of the body. Sometimes, games can also be played indoors. Badminton courts and even some swimming pools are found indoors.

   There are many different types of outdoor exercises. These include tennis, cycling and even rock climbing. Most people enjoy outdoor activities because they like being in the Sun or are attracted to its sense of peace and quiet. Yet there are others who like the wind blowing against them.

Exercise 4: [●●○]

Animation traditionally is done by hand-drawing or painting successive frame of an object, each slightly different than the proceeding frame. In computer animation, although the computer may be the one to draw the different frames, in most cases the artist will draw the beginning and ending frames and the computer will produce the drawings between the first and the last drawing. This is generally referred to as computer-assisted animation, because the computer is more of a helper than an originator.

In full computer animation, complex mathematical formulas are used to produce the final sequences of pictures. These formulas operate on extensive databases of numbers that defines the objects in the pictures as they exist in mathematical space. The database consists of endpoints, and color and intensity information. Highly trained professionals are needed to produce such effects because animation that obtains high degrees of realism involves computer techniques from three-dimensional transformation, shading, and curvatures.

High-tech computer animation for film involves very expensive computer systems along with special color terminals or frame buffers. The frame buffer is nothing more than a giant image memory for viewing a single frame. It temporarily holds the image for display on the screen.

A camera can be used to film directly from the computer’s display screen, but for the highest quality images possible, expensive film recorders are used. The computer computers the positions and colors for the figures in the picture, and sends this information to the recorder, which captures it on film. Sometimes, however, the images are stored on a large magnetic disk before being sent to the recorder. Once this process is completed, it is replaced for the next frame. When the entire sequence has been recorded on the film, the film must be developed before the animation can be viewed. If the entire sequence does not seem right, the motions must be corrected, recomputed, redisplayed, and rerecorded. This approach can be very expensive and time – consuming. Often, computer-animation companies first do motion tests with simple computer-generated line drawings before selling their computers to the task of calculating the high-resolution, realistic-looking images.
