Who hasn’t enjoyed eating peanuts? Did you know that although peanuts look like nuts and taste like nuts, they aren’t nuts at all? They belong to the pea family, so they are called peanuts. The peanut grows flowers above ground, but its “fruit” grows underground. It grows in more countries than most other “nuts”.
The peanut is a native South American plant. Scientists believe that it grew wild in Brazil long ago. They think that for several thousand years the early peoples of South America made it a part of their diet. These peoples were nomads who moved on when a natural food could no longer be found in one area. Along the way they probably let fall some peanuts, which got into the ground and grew. This is believed to be the way the plant reached the place where the Incas（印加人）lived. The Incas, from about 1100 to 1532, thought highly of peanuts. The peanuts were eaten in several forms and used as sacrificial offerings（祭品）to the Incan Sun God. Later in the 16^th century, European soldiers had brought peanuts to other parts of the world, including North America, Africa, Asia, Europe, and Pacific Islands.
Although peanuts were found native in South America, they are now grown in almost every country that has warm weather. India produces the most peanuts. China’s production is next, followed by the United States.
The peanut is special in more ways than one. It can be eaten raw, boiled, roasted, or fried. Hundreds of widely different products have been made from it. Carver, an American scientist, set himself the task of discovering new uses for eating and for many other products.
Peanuts are very highly nutritious and are also high in protein （蛋白质）. Americans use about seven-tenths of their protein in the form of meat. In India, where the poor can’t pay for meat or milk, peanut meal and peanut milk have been produced. These have been a great help to the poor.
New products are continually being made from peanuts, among them peanut cheese and a powder that becomes peanut butter when water is added. The fact is that peanuts are so healthy that they were used by astronauts. The unusual nut that isn’t a nut is one of nature’s most amazing gifts.

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.

1. 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.

2.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.

3.What’s the best title of the passage?

A. Your Eyes Knows                               B. Your Nose Knows  

C. Your Mouth Knows                             D. Your Tongue Knows
