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.

People have their own ways of saying things with their own special expressions. Some of these expressions are easy to understand. “As Easy as Falling off a Log (圆木)” is one such expression. It describes a job that does not take much effort. If you ever tried to walk on a falling tree log, you may understand what the expression means. It is easier to fall off the log than to stay on it.
There are several other expressions that mean the same thing. And their meaning is as easy to understand as falling off a log. One is “Easy as Pie.” Nothing is easier than eating a piece of sweet juicy pie, unless it is a piece of cake. “A Piece of Cake” is another expression that means something is extremely easy to do.
Another expression is “As Easy as Shooting Fish in a Barrel (桶)”. Clearly, fish in a barrel will be much easier to shoot than fish in a river. In fact, it would be as easy as falling off a log.
Sometimes, things that come to us easily also leave us just as easily. In fact, there is an expression “Easy Come Easy Go”. Another easy expression is “To Go Easy on a Person”. It means to treat a person kindly or gently, especially in a situation where you might be expected to be angry with him. A wife might ask her husband to go easy on their son, because the boy did not mean to destroy the toy. If you want to borrow some money to fix the car, you should look for a friend who is an “Easy Touch”. An easy touch or a soft touch is someone who is kind and helpful.
And there is one more expression that means do not worry or work too hard. Try to keep away from difficult situations. “Take it easy”, until we meet again.

A small boy at summer camp received a bag of cookies in the mail from his mother. He ate a few, and then put the rest under his bed. The next day, after lunch, he went to his tent to get a cookie. The box was gone.
That afternoon a camp leader saw another boy sitting behind a tree. He was eating the stolen cookies! “That young man,” he said to himself, “must be taught not to steal.”
He returned to the group and found the boy whose cookies had been stolen. “Billy,” he said, “I know who stole your cookies. Will you help me teach him a lesson?”
“Well, yes. But aren’t you going to punish him?” asked the puzzled boy.
“No, that would only make him hate you.” the leader explained. “I want you to call your mother. Ask her to send you another box of cookies.”
The boy did so and soon received another box of cookies. “Now,” said the leader, “the boy who stole your cookies is down by the lake. Go and share your cookies with him.”
“But he’s the thief!”
“I know, but try it—see what will happen.”
Half an hour later, the camp leader saw the two come up the hill, hand in hand. The boy who had stolen the cookies was trying to get the other to accept his toy knife. The other boy was just refusing the gift from his new friend. He said that a few cookies weren’t that important anyway.
