“If you want to see a thing well, reach out and touch it!”

　　That may seem a strange thing to say．But touching things can help you to see them better．

　　Your eyes can tell you that glass ball is round．But by holding it in your hands, you can feel how smooth(光滑的)and cool the ball is．You can feel how heavy the glass is．

　　When you feel all these about the ball, you really see it．

　　With your skin(皮肤)，you can feel better．For example, your fingers can tell the difference between two coins in your pocket．You can feel a little drop of water on the back of your hand, too．

　　You can even feel sounds against your skin．Have you ever wanted to know why some people like very loud music?They must like to feel the sounds of music．

　　All children soon learn what“Don't touch!”means．They hear it often．Yet most of us keep on touching things as we grow up．In shops, we touch things we might buy, such as tools, clothes and so on．To see something well, we have to touch it．

　　The bottoms(底部)of our feet can feel things, too．You know this when you walk on warm sand, cool grass or a bad floor．All feel different under your feet．

　　There are ways of learning to see well by feeling．

　　One way is to close your eyes and try to feel everything that is touching your skin．Feel the shoes on your feet, the clothes on your body, the air on your skin．At first, it is not easy to feel these things．You are too used to them!

　　Most museums are just for looking．But today some museums have some things to touch．Their signs say：

　　“Do touch!There you can feel every thing on show．

　　If you want to see better, reach out and touch．Then you'll really see!”

阅读理解。阅读下列材料，从A、B、C、D四个选项中选出最佳答案。

　　Different weather makes people feel different．It influences health, intelligence(智力)and feelings．

　　In August, it is very hot and wet in the southern part of the United States．People there have heart trouble and other kinds of health problems during this month．In the Northeast and the Middle West, it is very hot at some times and very cold at other times．People in these states have more heart trouble after the weather changes in February or March．

　　The weather can also influence intelligence．For example, in a 1983 report by scientists, IQ(智商)of a group students were very high when a very strong wind came, but after the strong wind, their IQ was 10％ below．The wind can help people have more intelligence．Very hot weather, on the other hand, can make it lower．Students in many schools of the United States often get worse on exams in the hot months of the year(July and August)．

　　Weather also has a strong influence on people's feelings．Winter may be a bad time for thin people．They usually feel cold during these months．They might feel unhappy during cold weather．But fat people may have a hard time in hot summer．At about 18℃, people become stronger．

　　Low air pressure may make people forgetful．People leave more bags on buses and in shops on low-pressure days．People feel best at a temperature of about 18℃．

　　Are you feeling sad, tired, forgetful, or unhappy today? It may be the weather's problem．

　　Have you ever walked into a room and felt relaxed? It could be because the walls painted blue, a calm and peaceful color．

　　Sometimes colors can affect(影响)our feelings and moods(情绪)．Some colors can make us feel calm and peaceful(安静的)．Blue is one of these．Wearing blue clothes or sleeping in a blue room is good for our mind and body, because this color gives us good feelings．Blue is also the color of sadness, so you may say “you’re feeling blue” when you’re feeling sad．White is another calm color．You should wear white clothes if you’re feeling nervous．White is also the color of purity(纯洁)．Many women like to be in white on their wedding(婚礼)day．Green is the color of nature．It can give us more energy(干劲，活力)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 weather use warm colors in their homes like orange and yellow instead of(代替)white and blue．

　　Orange shows joy(快乐)．It can bring you success and cheer you up(使……振奋)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(智慧)．Some people like this color when they study for exams．For example, they may use yellow paper．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．
