If I ask you to shut your eyes and gave you a piece of apple to eat, would you be able to tell me what it is just by tasting it? Of course, you could. Your tongue is covered with tiny “taste buds” which help you know what different foods taste like. Do you know that foods would taste different if you did not have a nose? This experiment shows how important your nose is when you taste things.
What You Need:
• a friend to help
• small pieces of any food like carrot, orange, banana
• small pieces of apple, raw(生的) potato, and onion
What You Do:
There are actually three different experiments. You and your friend should take turns to try them on each other.
Experiment 1:
Have your friend close her eyes and open her mouth.
Give her a piece of the food and ask her to taste it.
Then, ask her what she thinks it is. She will probably guess correctly.
Experiment 2:
While your friend has her eyes closed, give her a piece of the raw potato. At the same time, hold a piece of apple right under her nose. Ask her to eat the potato (but don’t call it by name) and tell you what she thinks it is. She will say it is a piece of apple!
Experiment 3: (for the brave)
Take a piece of raw onion. You don’t have to close your eyes this time. Squeeze your nose closed with your other hand so that no smells can get into your nose. Now take a nibble of the onion. Surprise! As long as you hold your nose, you will not be able to taste the onion.
The Science Secret
You already know the science secret. Your nose and your tongue work together to make food taste the way it does. Your tongue, however, can taste only certain flavors like salty, bitter, sour, and sweet. All of the other “tastes” are actually “smells,” and you need your nose to “taste” them. Oh, and you might use this science secret the next time you are told to eat something you don’t like the taste of. If you hold your nose while you eat it, you won’t “taste” it at all.According to this article, what could a reader know about food?
| A．People hold their noses to eat onions. |
| B．If you can smell potatoes, you will taste apples. |
| C．People need a sense of smell to taste some food. |
| D．If you close your eyes, food will taste better. |
What is the most likely reason Experiment 3 is called “for the brave”?
| A．You keep your eyes open. | B．You have to eat a raw onion. |
| C．You have to squeeze your nose. | D．You do the experiment alone. |
What’s the best title of the passage?
| A．Your Eyes Knows | B．Your Nose Knows |
| C．Your Mouth Knows | D．Your Tongue Knows |
Once upon a time， there was a king． He only had one leg and one eye，but he was very smart and kind． Everyone lived a happy and healthy life because of the king． One day， the king was walking through the palace hallway and saw the paintings of his ancestors（祖先）．He thought that one day his children would also walk in the same hallway and remember all the ancestors through these paintings．He wanted his children to remember him，too．So he invited many famous artists
to his palace．
All of the artists began to think about the king's physical disabilities（生理缺陷）． How could his painting be made very beautiful？It was not possible．They weren't sure what his painting would be like．So one by one， they all started to politely refuse to make a painting of the king．
But suddenly one artist raised his hand and said he would make a very nice painting of the king． The king became happy hearing that． Then the artist started painting． After a long time， the painting was ready．
When the artist showed the painting， everyone was shocked． In the painting， the king was sitting on a horse， on the one﹣leg side， holding his bow （弓箭） and aiming （瞄准） something with his one eye closed． The king was very happy and gave him lots of money．
As we all know， no one is perfect． So we should try to focus on （关注） others' advantages instead of their disadvantages． Just take an optimistic view （乐观的观点） of the event． Everyone can do a good job．
（1）What did the king see in the palace hallway？
（2）Why did the king invite artists to draw a painting of him？
（3）Was it an easy job or a hard job to draw a painting of the king．
（4）How did the king like the painting？

Do you think laughter can help you deal with pain？ Scientists from Britain did two experiments（实验）． The first was done in a lab． People wore special wristbands（腕带）． Some of them were asked to watch comedies while others watched serious programs． Then the scientists tightened（勒紧）the wristbands to see how much pain the people could feel．
The other test was done at an art festival． Some people watched a comedy show and others watched a drama（戏剧）． At the same time， they had to put their backs against the wall and keep their legs bent（弯曲的）just like sitting on a chair． They did this before and after the show．
Scientists found that just 15 minutes of laughter improves people's ability to stand pain by 10%．However， the serious programs and the drama didn't make a difference to pain at all．
The study found that the magic power of laughter comes from endorphins（内啡肽）． These are chemicals（化学物质）． They are produced by the human body． They make you feel less pain and can make people feel happier． Exercise can produce endorphins．Your muscles（肌肉）move in and out when you are laughing．Scientists believe that this makes your muscles tiring，so we start to produce endorphins．
Scientists also found that the only real and relaxing laughter works not just polite laughter．
Next time you have a headache，get together with a group of Mends，watch a funny movie and laugh．You will soon feel a lot better because laughter is the best medicine．

As the fifth of seven children， I went to the same public school as my three elder sisters and brother．Every year， each child from the third grade took part in an old school tradition﹣the plant sale held in early May， just before Mother's Day．
That year I was old enough to take part in it． I wanted to surprise my mother， but I didn't have any money． I told my elder sister about it and she gave me some money． When I arrived at the plant sale， I carefully chose my favorite． I watched each plant seriously to make sure that I could find the best geranium（天竺葵）． After school， with the help of my sister I bid it on the neighbor's porch（门廊）．On Mother's Day， I remember how bright my mother's eyes were and how alated she was at my gift．
