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

Teeth are a key part of your body. Strong, healthy teeth help you chew all kinds of foods that help you grow. They help you speak clearly. That's why it's necessary to take great care of your teeth. The following suggestions help you have healthy teeth for life.

One is to brush your teeth at least twice a day, more often if possible. You'd better brush your teeth after every meal, especially a sweet snack, which is the best way to protect against tooth disease（疾病）. It's necessary to clean the front, back and top surfaces of all your teeth.

Another step you can take to protect your teeth is flossing. Floss is a thin thread（丝线）that moves between teeth to remove food that your toothbrush can't reach.

You should pay attention to what you eat. Eating foods that are high in sugar can lead to tooth disease. That's because bacteria that causes tooth disease loves sugar. You can eat fruits and vegetables instead, which are good for your body as well as your teeth.

Healthy teeth will always bring you happiness. Do you want to have white and healthy teeth? Please take care of your teeth!
