四、教具准备(Teaching aids):

五、教学步骤(Teaching step):

Step 1 Revision(复习)

1.复习英文歌"Good morning"进行师生问候。

2.用颜色图片复习前面要求"二会"的单词yellow, blue,black.

Step 2 Presentation (介绍新课)

1.学习句型What colour is ...? It's ....

(1)出示黄色香蕉图片，提问

T:What's this?

待学生用It's a banana.之后，老师接着引出新句型。

T:What colour is the banana?

老师提示学生用It's yellow.回答。

板书：yellow

(2)分别出示实物玩具：蓝色的飞机和黑色的小汽车，用同样的问题提问，加深学生对What colour is ...?的理解, 然后板书句子:What colour is the plane? It's blue.

提醒学生不要把It's blue说成It's a blue.

2.学习新单词red,green,brown,orange,white

(1)用上述方法分别出示红色的小汽车，棕色的小狗的图片，这一次让学生问老师答的形式引出新单词red,green,brown.

老师举起小汽车图片

(学生齐问) Ss:What's that?

T:It's a car.

Ss:What colour is the car?

T:It's red.

板书：red

（3） 学生拿出水彩笔，画出一棵绿色的大树。

教师举起图片，提问：“What color is it”

学生回答：“It’s a tree.What color is it?”

教师回答：“It’s green.”

板书：green

教师再举起一张森林被砍伐的图片，树木只剩下树桩，有的地方变成了沙漠，小鸟和野生动物无处生存。

教师问学生：“如果世界没有了绿色，那将会是什么样子？

生回答：世界将会变成一片沙漠。

野生动物们就会灭绝。

沙尘暴就会盛行

大气污染会更加严重。

教师总结：如果没有了树木，我们的世界就会变得死气沉沉，没有了生机。各种环境污染会更加严重。所以，从现在开始我们要保护树木，保护绿色。

同法教brown,并板书。 同时提醒学生注意这几个单词中的[r]是一个翘舌音，发音时舌头要翘起来。

(2)出示一个实物"橙"，提问

T:What's this?

Ss:It's an orange.

T:What colour is the orange? (请个别学生回答)

S:It's orange. (板书 orange,跟读)

老师补充一句：An orange is orange. 告诉学生orange 是一个多义词，以后将会学很多象这样的词。

(3)出示一个玩具绒毛猫，提问

T:Is this a black cat?

Ss:No,it isn't.

T:It's a white cat. (板书 white,跟读)

Step 3 Practice (操练)

单词练习：

1.打开书本，听Part A 的录音两遍，全班跟读。

2.看黑板的单词齐读、个别读。

3.游戏：

(1)对号入座

游戏方法：老师把八张颜色卡纸分别发到每一组的第一个同学，播放快速紧张的音乐，音乐开始，持卡片的同学马上把卡片往后传，音乐停止，卡片落在哪一个同学手中， 他马上要把该卡片贴到黑板上与卡片颜色一致的单词的右边， 最先完成而且答案又正确者，该组得１分。

(2)Bingo game

老师出示一个圆形转盘，（转盘由硬纸做成， 分底面两块，大小一样，底块的一面是由８个等分的、不同颜色的扇形构成，颜色的依次顺序按黑板板书的顺序；上面的一块是剪去八分之一扇形的白色圆，把两个圆重合，面块盖住底块， 底块只露出与面块被剪部分对应的颜色，制成两个圆都可以转的转盘）慢慢转动， 让学生看看里面的颜色。游戏开始，先让学生在练习本上用英语写下某一种或两种相邻的颜色名称，然后由全班同学一齐喊one,two,three,老师快速转动转盘的底面任意一块，突然停止， 看哪种颜色露出来，如果学生写的颜色与露出来的颜色一致，就马上说"Bingo", 他所在的小组得１分，这游戏玩三次。

句型练习：

用投影仪把Part B 的图打出来，盖住句子部分，把学生分成男女两组，用What colour is ...?It's ...进行问答，然后把句子部分也打开，听录音，跟读。 Step 4 Communication activity(交际活动)：

把学生分成四人小组，互相用Hello!Good morning!I'm...等打招呼、自我介绍后，一齐说Let's draw a fish/an apple...,然后各人开始画，并涂上颜色， 注意涂颜色时别让别人知道自己涂的是什么颜色，完成后，大家一齐把自己的画反放在桌面上，然后问What colour is the apple? 其他同学用It's...猜，猜对了轮到他问，其他同学猜。

Step 5 Sum up (小结):

让学生看黑板板书的内容总结这一节课所学的八种颜色的名称和询问或回答有关颜色的句子。

Step 6 Homework (布置作业)

抄写Part A 的单词，听Part A & B 的录音，并跟读。

附板书设计：

Unit Eight

What colour is the plane/car/...?

It's yellow.

It's blue.

It's black.

It's red.

It's green.

It's brown.

It's orange.

It's white.

课后反思：本课通过多种多样的学习方式，充分调动了学生的学习积极性。学单词的时候，利用实物教学，直观性强。在学习“green”的时候，我首先锻炼了学生的动手能力，让学生画了一棵树，然后再出示树木被砍的图片，让学生认识到绿

篇三：Colors 教案

篇四：Oracle DISPLAY COLOR终极解决方案

Checking monitor: must be configured to display at least 256 colors >>> Could not execute auto check for display colors using command /usr/openwin/bin/xdpyinfo. Check if the DISPLAY variable is set. Failed <<<<

解决 要点主要是要运行host +打通 接受控制；不是去安装啥补丁！安装啥包

如果碰到以上这个问题，就跟着下面的设置一定可以搞定！如果还是不能拿就是RP问题了。。。

1．先进入ROOT内：

su – root password:xxxxx

DISPLAY=:0.0; export DISPLAY

echo $DISPLAY

cd /usr/openwin/bin ./xhost

access control enabled, only authorized clients can connect

./xhost +

access control disabled, clients can connect from any host

2. 然后进入ORACLE su - oracle

$ DISPLAY=:0.0; export DISPLAY

$ echo $DISPLAY

:0.0

$ ls

doc response stage

install runInstaller welcome.html

$ ./runInstaller

怎么样，解决了吧！就是这么简单！！

如果包没安装请看我的另外一个文件！

篇五：Color

1.4 Color

Keeping the theme of the group in mind., a designer must incorporate in each garment a pleasing combination of all the elements of good design. These elements are color, fabrication, line, shape, and detail. One of them usually predominates in a design. These same ingredients are essential to every art form, but they alone are not a recipe for success, and they cannot substitute for experience. Fashion changes continually; there are no hard and fast rules.

Color can be the basis for a whole group or line. It is the first element to which consumers respond . People relate personally to color , usually either selecting or rejecting a garment because of its color appeal. Therefore, designers must consider their customers and provide colors that are both appealing and flattering.

People relate personally to color because it causes emotional responses, some of them based on events in their lives and on their culture. People in many agricultural countries, who have deep roots in folk traditions, have been exposed to different uses of color than people who live in business-oriented Western countries.

People connect certain colors with holidays and seasons. They expect to see the colors of autumn leaves in fall clothing,reds and greens for the winter holidays,the pastels of flowers in the spring. and refreshing white for the summer. All manufacturers include some of these colors in

their lines.

Color Selection

Every line should include a range of colors that appeals to a variety of customers. Within the line each group is usually formulated around a color plan consisting of as few as two colors or many colors. Color choices must reflect season. climate,and type of garment. Active sportswear, for example, employs much more vivid colors than spectator sportswear.

The line's color story should include some fashion colors selected from research provided by trade associations, fiber companies, or design report predictions. By basing a color story on these predictions. the designer is assured that the group will be in the mainstream of fashion. Sometimes the designer selects one or two colors from the predictions and then adds his or her own color choices to balance them. The group is then rounded out with staple colors such as neutrals, darks. white, or black. In any case. the color story must be meaningful, not just a group of unrelated colors. It might be all brights. or all muted. or a balance of darks and lights.color Relationships within a Garment.

Color Relationships within a Garment

There are several systems. all using measured scales, to guide in the selection of color combinations. Primary and secondary colors differ from one system to another. But looking at a rainbow will show you the basic

order of colors' relationship to one another.

The Brewster and Prang theories define red,yellow, and blue as the three primaries from which all other colors are derived. Mixing yellow and red paints creates orange; red and blue create purple; and blue and yellow create green the three secondary colors. Mixtures of primary and secondary colors create every color in between. The entire spectrum is often arranged into a color wheel to demonstrate the concept more clearly. However, the working fashion industry pays little attention to theories and systematic color relationships. basing selections instead on intuition and researched color forecasts.

There are no hard and fast rules for the use of colors. Rather. two colors are harmonious if they are used so that one color enhances the beauty of the other . Colors are now combined in many more unusual ways than ever before. Colors that used to be appropriate only for evening are now used also in sportswear. Ethnic influences on fashion have changed our view of color combinations, making us more receptive to new ideas. In addition. colors run in fashion cycles just as styles do. Color combinations that look right to us now will not work with the looks that are new a few years hence.

Guidelines for Possible Color Combinations Monochromatic or tonal color schemes employ varying values and intensities of one hue. (Mono means one and chroma means hue or

color. ) The resulting look is very refined. However, textural variety is needed to create interest.

Analogous colors lie next to each other on the color wheel and are related in hue. Used together, they present a rhythmic, exciting effect. An example is a combination of royal blue and turquoise (blue-green). blue being the common hue.

Complementary colors are opposite each other on the color wheel. The contrast makes both colors more intense. They may be used in equal amounts, or one color may merely accent the other. A Traditional complementary color scheme is the Christmas theme of red and green.

A triad is a combination of three colors equally distant on the color wheel. such as green. purple. and orange. This is a much more unusual color combination and is more difficult to achieve successfully. Illusions Created by Color

Color can also create illusions. For example. a garment in one color adds to the illusion of height. Warm. Light., or bright colors advance visually. making a design seem larger; cool or dark colors recede. causing the figure to look small or slender. Both intensity and value contrasts are frequently used to disguise figure problems.

Color and Fabric

Color is interpreted in the medium of fabric. If colors are chosen first. then prints are colored in the desired scheme and solids dyed to

match .sometimes,however,the fabric itself will inspire the color group.
