The fact that blind people can see things using other parts of their bodies apart from their eyes may help us to understand our feelings about color._________(46)_________(47)These discoveries have grown into a whole discipline of color psychology that now finds application in everything from fashion to interior decoration. Some of our preferences are clearly psychological.________(48)For primitive man,activity during the day meant hunting and attacking,which he soon saw as red,the color of blood and rage and the heat that came with passive defense and self-preservation._________(49)People exposed to bright red show an increase in respiration rate,heartbeat, and blood pressure;red is exciting._________(50)Because of its exciting connotations,red was chosen as the signal for danger,but closer analysis shows that a vivid yellow can produce a more basic state of alertness and alarm,so fire engines and ambulances in some advanced communities are now rushing around in bright yellow colors that stop the traffic dead.__________（49）A:Dark blue is the color of the night sky and therefore associated with passivity and calm, while yellow is a day color with associations of energy and incentive.B:Similar exposure to pure blue has exactly the opposite;it is a calming color.C:Color psychology is concerned with the effects of color on mood,emotion,behavior.D:Manufacturers have discovered by trial and error that sugar sells badly in green wrappings, that blue foods are considered unpalatable,and that cosmetics should never be packaged in brown.E:If they can sense color differences then perhaps we,too,are affected by color unconsciously.F:Experiments have shown that colors partly because of their physiological associations,also have a direct psychological effect.

第三篇Ways to Create Colors in a PhotographThere are two ways to create colors in a photograph.One method called additive,starts with three basic colors and adds them together to produce some other color. 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(a purplish pink);green and blue mix to produce cyan(a bluish green).When equal parts of all three of these primary-colored beams of light overlap（重叠）,the mixture appears white to the eye.In the subtractive process colors are produced when dye（染料）absorbs some wavelengths and so passes on only part of the spectrum.The subtractive primaries are cyan,magenta and yellow; these primaries or dyes absorb red,green and blue wavelengths respectively,thus subtracting them from white light. These dye colors are the complementary colors to the three additive primaries of red,green and blue.Properly combined,the subtractive primaries can 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.What does the passage mainly discuss?A: Recent developments in camera technology.B:How to make white light.C:The additive and subtractive methods of producing color.D:The discovery of the spectrum.

Verity Allen's New Show on Colors1 Different colors can affect us in many different ways;that's according to Verity Allen.In her new se- ries'Color me Healthy',Verity looks at the ways that colors can influence how hard we work and thechoices we make.They can even change our emotions and even influence how healthy we arc.2 "Have you ever noticed how people always use the same colors for the same things?" says Verity."Ourtoothpaste is always white or blue or maybe red.It'g never green.Why not?For some reason we think that blue and white is clean,while we think of green products as being a bit disgusting. It's the same for businesses.We respect a company which writes its name in blue or black,but we don't respect one that uses pink or orange.People who design new products can use these ideas to influence what we buy."3 During this four-pait series,Verity studies eight different colors,two colors in each program.Shemeets people who work in all teipects of the color industry,from people who design food packets to people who name the colors of lipsticks.4 Some of the people she meets clearly have very little scientific knowledge to support their ideas,such as the American"Color Doctor"who believes that serious diseases can be cured by,he use of colored lights. However,she also interviews real scientists who are studying the effects of green and red lights on mice,withsome surprising results.5 Overall,it's an interesting show,and anyone who watches it will probably find out something new.But because Verity goes out of her way to be polite to everyone she meets on the series,it's up to the viewers to make their own decisions about how much they should believe.Paragraph 5_______________A:The Same Colors for the Same ThingsB:Scientists' Surprising ResultsC:Verity's View on the Influence of ColorsD:Knowledge of the Interviewees on ColorsE:Studies in Verity's SeriesF:The Author 's Opinion About Verity's Shows
