1. Warm-up
Work in pairs. Ask your partner these questions.
1. How can you keep your health?
2. How can you cure a cold without going to a doctor?
3. What troubles did you have if you had flu?
2. Reading
Task 1
Can you explain the meaning of the following idiom? Mark is a lazy-bones.
Bones are classified according to the shape: long, short, flat, irregular, sesamoid and sutural.
1. Long bones:
Bones that are longer than they are wide are called long bones. They consist of a long shaft
with two bulky ends or extremities. They are primarily compact bones but may have a large
amount of spongy bones at the ends or extremities. Long bones include bones of the thigh, the
leg, the arm, and the forearm, e.g. the femur, the tibia, the fibula, the humerus, the ulna and
the radius. They provide places for the attachment of large muscles.
2. Short bones:
Short bones are roughly cube shaped with vertical and horizontal dimensions approximately
equal. They consist primarily of spongy bones which are covered by a thin layer of compact
bones. Short bones are found in the hands and feet, they include the bones of the wrist and
the ankle.
3. Flat bones:
Flat bones are thin, flattened, usually curved and provide muscle attachments. They protect
internal organs. Examples include bones of the skull, the pelvis, the sternum and the scapulae
4. Irregular bones:
Irregular bones have complicated shapes. They are primarily spongy bones that are covered
with a thin layer of compact bones. Their shapes are due to the functions they fulfill within
the body, e.g. they comprise the vertebrae, the spinal column, the wrist, the ankle and some
facial bones.
Other types of bones according to the shape are:
5. Sesamoid bones:
Sesamoid bones develop in some tendons in locations where there is considerable pressure,
tension, friction or stress. They may form in the palms of the hands and the quality varies
considerably from person to person. Examples include the patella (kneecaps).

6. Sutural bones:
Sutural bones are classified by their location rather than by their shape, they are parts of
sutural joints between the cranial bones. The number of sutural bones are considerable and
therefore these are un-named bones.

4. Writing
Read the text below and write down a few sentences about healthy way of life.
Healthy and slim.
According to some scientists our body is programmed for 100-120 years of life. In spite of
this fact we are growing old and dying much sooner.
Being healthy, fit and having a slim figure are inseparable parts of one thing. If you live a
healthy way of life, you feel fit and you look well, your health and beauty shine in your hair,
skin, eyes, nails and in all your behaviour and appearance. We have learned a lot about
correctly balanced nutrition, we understand the importance of exercise and sports and thinking
positively.
To be healthy and slim, active till old age, to do the best for our bodies, to keep them in
harmony with natural principles. Not a fashion, not a diet, but a healthy programme for all life
long. Eating healthy food makes you slim, being slim and attractive makes you happy and
healthy.
