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

If you were asked what your body is made of, probably you would say that it is made of flesh(肉体) and bones and covered with skin. You also know something about the blood which flows through it, and that there is a very important part which we call the brain.
But the flesh and the bones make up the largest part of the body, and there is a good deal to be learned about them. You know the general appearance of both flesh and bone from the parts of animals which you see in the butcher’s shop.
Bone is hard, and of a white color; indeed, it looks more like a piece of wood or stone than a part of a living animal. But bone is a real part of the living body, and it grows and is nourished (滋养)just as the body is. If a man breaks the bone of his arm or his leg, it is firmly bound up, to prevent the broken parts from moving out of the proper places, and in time then bone grows together again and becomes quite strong.
The bones are fastened together by various kinds of joints(关节). They form the framework of the body, and give it strength to retain its proper shape. This framework is called the skeleton(骨架). Some animals, such as worms and slugs, have no skeleton; and others, such as shellfish, have a kind of hard covering or skeleton outside.
The most important part of the skeleton is the backbone. It is so important that naturalists divide all animals into two classes,--- those which have a backbone and those which have none. All the higher animals, including man, have a backbone, or vertebral column as it is called. They are therefore called vertebrate (脊椎的)animals. The others are called invertebrate animals.
1.What’s our body made of?
A. Flesh
B. Flesh and bones.
C. Flesh, bones and flood.
D. Flesh, bones, flood and brain.
2.Where can we see flesh and bones from the parts of animals?
A. In the bookshop. B In the butchers’ shop.
C. At home. D. In the shopping mall
3.Why should the bones bound up firmly if they were broken?
A.To make the bones strong
B. To protect our arms and legs
C. To fasten the joints.
D. To prevent the broken parts from moving out of the proper places.
4. From the passage, we know higher animals are called .
A. backbone B. human beings
C. vertebrate animals D. skeleton
