Exercise

    Exercise is a way of keeping the body healthy through being active. Another name for exercise is physical fitness. Most people exercise in their spare time. Sports are some of the most popular ways to get exercise.

    The two main kinds of exercise are aerobic exercise(有氧运动)and anaerobic exercise(无氧运动). Sports such as football and basketball are great forms of exercises. {#blank#}1{#/blank#}

    Aerobic exercise is energetic movement that lasts for a certain period of time.{#blank#}2{#/blank#} The lungs and the heart work harder to bring in extra oxygen. Swimming, cycling, running and rapid walking are good examples of aerobic exercise.

    Anaerobic exercise is a powerful burst of movement followed by a period of rest. During anaerobic exercise the muscles need more energy than the body can make with its supply of oxygen. After the exercise a person feels out of breath because the muscles have worked without oxygen.

    {#blank#}3{#/blank#} 

    Exercise affects every part of the body in positive ways. It improves balance and coordination(协调).{#blank#}4{#/blank#}Exercise strengthens the heart and increases the lungs' ability to take in oxygen.

    The history of writing instruments, with which humans have recorded and conveyed thoughts and feelings, is the history of civilization itself. This is how we know about our ancestors and their life.

    The handy sharpened-stone was adapted into the first writing instrument. Around 24,000 BC, the cave man started drawing pictures with the stone onto the walls of his cave. {#blank#}1{#/blank#} Walls at the Apollo site in Namibia are believed to be the oldest rock paintings to date.

    Before paper came along, people used clay or wax tablets on which they wrote with sharp objects such as metal sticks or bones. Around 6000 years ago, the Egyptians invented the first paperlike material called papyrus. The word "paper" actually comes from the word "papyrus".

    {#blank#}2{#/blank#} Bones or metal sticks were no longer useful as the papyrus could not be scratched. So the Egyptians created a reed-pen perfect for the papyrus. {#blank#}3{#/blank#} And thus, ancient Egyptians transformed bamboo stems (茎) into an early form of a fountain pen.

    Another writing instrument that remained active in history for a long period was the quill (鹅毛) pen. Introduced around 700 AD, the quill was a pen made from a bird feather. Goose feathers were most common. {#blank#}4{#/blank#} For making fine line drawings, crow feathers were the best.

    When writers had better inks and paper and handwriting had developed into both an art form and an everyday occurrence, man's inventive nature once again turned to improving the writing instrument. {#blank#}5{#/blank#}

A. Now something was needed to write upon the papyrus.

B. The papyrus became the most popular material at that time.

C. Swan feathers were of a high quality, being rare and most expensive.

D. Bamboo stems were better and much more expensive than goose feathers.

E. This led to the development of the modem fountain pen in the 19th century.

F. These were mostly the stems of grasses, especially from the bamboo plant.

G. These drawings showed events in daily life like the planting of crops or hunting victories.
