BHave you ever walked into a room and felt relaxed？It could be because the walls were painted blue, a calm and peaceful color .Sometimes colors can affect our feelings and moods.Some colors can make us feel calm and peaceful.Blue is one of these.Wearing blue clothes or sleeping in a blue room is good for our mind and body, because this color makes a good feeling.Blue is also the color of sadness, so you may say you’re feeling blue when you are feeling sad.White is another calm color.You should wear white clothes if you are feeling nervous.White is also the color of purity(纯洁).Many women like to be in white on their wedding day.Green is the color of nature.It can give us more energy when we are feeling tired.Some colors can make you feel warm.These colors can give you a happy feeling.People who live in cold climates use warm colors in their homes like orange and yellow instead of white and blue.Orange shows joy.It can bring you success and cheer you up when you are feeling sad.Yellow is the color of the sun, so it can remind you of a warm, sunny day.Yellow is also the color of wisdom.Some people prefer this color when they study for exams.For example, they may use yellow school things.Red is one of the strong colors.Wearing red often makes us active.In short, we can try out different colors if we aren’t feeling our best.根据短文内容,选择最佳答案。 第 6 题 （ ）According to the passage, which color of the following can make you feel relaxed?A．Yellow.B．Orange.C．Red.D．White.

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.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.
