Concepts of reading have changed substantially over the centuries. During the 1950’s, and 1960’s especially, increased attention has been devote (51) defining and describing the reading process. (52) specialists agree that reading (53) a complex organization of higher mental (54) , they disagree (55) the exact nature of the process. Some experts, who regard language primarily as a code using symbols to represent sounds, (56) reading as simply the decoding of symbols into the sounds they stand (57) . These authorities (58) that meaning, being concerned with thinking, must be taught independently of the decoding process. Others maintain that reading is inextricably related to thinking, and that a child who pronounces sounds without (59) their meaning is not truly reading. The reader, (60) some, is not just a person with a theoretical ability to read but one who (61) reads. Many adults, although they have the ability to read have never read a book in its entirety. By some experts they would not be (62) as readers. Clearly, the philosophy, objectives, methods and materials of reading will depend on the definition one uses. By the most inclusive and satisfactory definition, reading is the ability to (63) the sound-symbol code of the language, to interpret meaning for various purposes, at various rates, and at various levels of difficulty, and to do (64) widely and enthusiastically. (65) , reading is the interpretation of ideas through the use of symbols representing sounds and ideas.
A. of
B. about
C. for
D. with

Colors There are two ways to create colors in a photograph. One method, called additive, starts with three basis colors and adds them together to produce some other colors. The second method, called subtractive, starts with white light (a mixture of all colors in the spectrum) and, by taking away some or all other colors, leaves the one desired. In the additive method, separate colored lights combine to produce various other colors. The three additive primary colors are green, red and blue (each providing about one-third of the wavelengths in the total spectrum). Mixed in varying proportions, they can produce all colors. Green and red light mix to produce yellow; red and blue light mix to produce magenta; green and blue mix to produce cyan. When equal parts of all three of these primary-colored beams of light overlap, the mixture appears white to the eye. In the subtractive process, colors are produced when dye (as in paint or color photographic materials) absorbs some wavelengths and so passes on only part of the spectrum. The subtractive primaries are cyan (a bluish green), magents (a purplish pink), and yellow; these are the pigments or dyes that absorb red, green and blue wavelengths, respectively, thus subtracting them form white light. These dye colors are the complementary colors to the three additive primaries of red, green and blue. Properly combined the subtractive primaries and absorb all colors of light, producing black. But, mixed in varying proportions, they too can produce any color in the spectrum. Whether a particular color is obtained by adding colored lights together or by subtracting some light from the total spectrum, the result looks the same to the eye. The additive process was employed for early color photography. But the subtractive method, while requiring complex chemical techniques, has turned out to be more practical and is the basis of all modern color films. Which of the following is NOT a pair of additive and subtractive primary colors
A. Yellow and blue.
B. Magenta and green.
C. Black and white.
D. Cyan and red.
