About ten men in every hundred suffer from color blindness in some way．Women are luckier．Only about one in two hundred is affected in this matter．So some people say it is safer to be driven by women．

There are different forms of color blindness．]n some cases a man may not be able to see deep red．He may think that red，orange and yellow arc all shades（色调）of green．Sometimes a person cannot tell the difference between blue and green．In rare cases an unlucky man may see everything in shades of green--a strange world indeed．

Color blindness in humans is a strange thing to explain．In our eyes there are millions of very small things called “cones”．These help us to see in a bright light and to tell differences between colors．There are also millions of “rods”，but these are used for seeing when it is nearly dark．They show us shapes but no color．

Some insects have favorite colors．Mosquitoes（蚊子）like blue but do not like yellow．A red light will not attract insects，but a blue lamp will．In a similar way humans also have favorite colors．Yet we are lucky．With the aid of the cones in our eyes We can see many beautiful colors by day，and with the aid of the rods we can see shapes at night．One day we may even learn more about the invisible（看不见的）colors around us．

1．With the help of the cones，we can _________．

A．see in a weak light                                   B．tell different shapes

C．kill mosquitoes                                           D．tell orange from yellow

2．Why do some people say it is safer to be driven by women?

A．Women are more careful．

B．There are fewer color blind women．

C．All of them see everything in shades of green．

D．None of them has trouble in recognizing（识别）colors．

3．This passage is mainly about _________．

C．color blindness                                          D．the invisible colors around us

　　What's your favorite color? Do you like yellow, orange or red? If you do, you must be a person full of hopeful happy feeling about life. Do you like gray and blue? Then maybe you are quiet, and you would rather go after than go before. And sometimes you feel unhappy.

　　If you love green, you are strong-minded. You wish to do everything well and want other people to see you are successful. At least this is what psychologists tell us. They tell us that we don't choose our favorite colors as we grow up. If you happen to love brown, you did so as soon as you opened your eyes or at least as soon as you could see clearly.

　　A yellow room makes us feel happier and more comfortable than a dark green one; and a red dress brings warmth and gladness to the saddest winter day.

　　Light and bright colors make people not only happier but more active. It is a fact that factory workers work better, harder, and have fewer accidents when their machines are painted orange rather than black dark gray.

　　Remember, then, that if you feel low, you can always brighten your day or your life with a new shirt or a few colorful things.

　　Remember also that you will know your friends better when you find out what colors they like and dislike. And don't forget that anyone can guess a lot about your character when you choose something in different colors.

　　“Cool” is a word with many meanings. It means a little bit cold at first. As the world has changed, the word has got many different meanings.

　　“Cool” can be used to express(表达) feelings of interest in almost everything. When you see a famous car in the street, maybe you will say, “It's cool.” You may think, “He's so cool.” When you see your favorite football star.

　　We all enlarge the meanings of “cool”. You can use it to mean “new” or “surprising”, here is an interesting story. It shows the way the word is used. A teacher asked her students to write about the waterfall(瀑布) they had visited. One of her students just wrote, “It' so cool.” Maybe he thought it was the best way to show what he saw and felt.

　　But the story also shows some people do not have enough words. Without “cool”, they have no other words to show the same feeling. Can you think of any other words like “cool” with so many meanings? If you can, they are also very “cool”.
