B.The three most famous Egyptian mummies.

C.Mummy and mummification.

D.A safe passage to the afterlife

AB. The reason why Egyptians made and gave up making mummies.

AC. Different ways to make mummies.

When you think of a mummy what comes to mind? Most of us usually picture an Egyptian mummy wrapped in bandages and buried deep inside a pyramid. While the Egyptian ones are the most famous, mummies have been found in many places throughout the world, from Greenland to China to the Andes Mountains of South America.

__1. ____

A mummy is the body of a person that has been preserved after death. Normally when we die, bacteria and other germs eat away at the soft tissues (such as skin and muscles) leaving only the bones behind. Since bacteria need water in order to grow, mummification usually happens if the body dries out quickly after death. The body may then be so well preserved that we can even tell how the dead person may have looked in life.

__2. ____

Mummies are made naturally or by embalming（以香油涂尸防腐）, which is any process that people use to help preserve a dead body. Mummies can be dried out by extreme cold, by the sun, by smoke, or using chemicals such as natron（氧化钠）. Some bodies become mummies because there were favorable natural conditions when they died. Others were preserved and buried with great care.

__3. ____

The ancient Egyptians believed that mummifying a person's body after death was essential to ensure a safe passage to the afterlife. Over time almost all Egyptians who could afford to became mummies when they died -- a total of about 70 million mummies in 3,000 years. By the 4th century AD, many Egyptians had become Christians and no longer believed that mummification was necessary for life after death. Eventually, the Egyptians gave up the art and science of making mummies.

__4. ____

So where did all the mummies go? Sadly, most were grabbed in ancient times by robbers looking for treasures wrapped up in the bandages. Countless mummies were also destroyed during the Middle Ages, when they were ground into powders to make supposedly magical pills. Later on, modern treasure hunters rushed into their tombs carelessly looking for artifacts and souvenirs. Even industry aided the destruction by using mummies' bandages to make paper or burning their bodies for fuel.

__5. ____

The best preserved mummies are those of the pharoahs and their relatives. These mummies tended to be more carefully embalmed and protected from harm. The mummies that have survived allow us to look back into the past and know something of the ancient Egyptians and their time. Three of the most famous Egyptians mummies are Tutankhamen, Seti I and Rameses II (Ramses the Great).

There must be a better way to teach our students __________value of __________life than just inviting an old professor to give a boring lecture.

We’ve all seen them: perfectly toned famous people on late-night television telling us that we too can develop rock-hard abdominal muscles（腹肌）. It’s easy! Just pay $149.99 for the Torso Track or $149.75 for the Ad-Doer and watch those unwanted inches leave your waist. Americans spend tens of million of dollars on various products to firm up their fat around the waist.

And did they work? Not necessarily. Independent studies have concluded that most of these products-no matter who approved them or how expensive they are-shape your midsection no better than old-fashioned stomach crunches（仰卧起坐）. Some can even cause injury-like the $518.99 Body Shaper-Q8SP, which left electrical burns on some researchers at the University of Wisconsin, La Crosse. Others, like the popular Ab-Doer, trpically burn less energy than a gentle walk, according to a study to be published in September by the American Council on Exercise.

The fact is that many Americans don’t have the biological makeup to develop an obvious abdominal muscles. They are either unable to get the necessary muscle mass or they can’t lose enough fat to make a difference. Even if the underlying muscles are well developed, and it takes to hide it is one-sixteenth of tan inch of fat. That’s enough to dismiss most healthy women as well as plenty of guys who do crunches every day.

So what works best? In its new study, the exercise experts researched on the results of the popular Ab-Doer. A lengthy TV advertisement promises that just 10 minutes a day performing such movements as “Body Boogies” and “Good Mornings” will “help form those muscles the fun and easy way without diets.” Steven Loy, professor at California State University, Northridge, tested the promise by measuring the electrical activity produced by the abdominal muscles during three Ab-Doer movements. He and his colleagues then compared the results with those produced during traditional exercises. They determined that the muscles were no more active, and in some cases less so, when exercisers were using the Ab-Doer.

Taking a broader approach, researchers at San Diego State University compared 13 abdominal exercises for their ability to develop the central abdominal muscles. They concluded, in a report published in May, that the most effective exercises kept turning the body and worked the muscles the entire time. Among the winners: the bicycle movements-so called because it looks as if you are riding a bike while lying flat on the floor-and exercises performed on the “Captain’s Chair”, a product typically found in gyms that helps hold the body in the air while you raise your legs up toward your chest. Researchers suggested that a varied routine of the different exercises could deliver the best results.
