The earth is not the only【C1】______that travels around the sun. With it are eight other planets, fellow members of the sun's family.
Two of them are【C2】______while the other six【C3】______from the sun than the earth is. The farther they are, the longer【C4】______they【C5】______around the sun. People noticed long ago that these traveling bodies moved around in the sky【C6】______definite paths. It is a【C7】______called gravity that【C8】______them in their paths.
We know that every little bit of matter in the【C9】______pulls upon every other bit of mater. The pull between two bodies is【C10】______to the product of their masses. Because the sun is so large that pulls【C11】______the sun and the planets are thus great. If it【C12】______not for these pulls, the planets【C13】______off into space. In the same way【C14】______exists a pull between the earth and the moon, which keeps the moon【C15】______in its orbit around our planet, the earth. The gravity holds you to its surface, and pulls back to it the ball which you【C16】______into the air. Of course the ball also pulls【C17】______the larger earth, but the earth is so much larger that the pull【C18】______.
Now remember that large bodies exert a greater pull on any body than smaller ones which contain【C19】______material. But each object in the universe, no matter how small, pulls on all other objects【C20】______extent.

Pain is easier to endure if you know you can end it. Speakers at a session on pain at the British Association's psychology section have new evidence to support this idea for two common experiences of pain: in childbirth and at the dentist's. On the other side of the coin, their inability to control pain may explain why some people with continual pain have psychological problems as well.
Dr. J. Robinson found out about the phenomenon of self-controlled pain almost by accident. He was studying the effects of analgesics used to control pain during childbirth and as part of the experiment made it possible for women having their child to press a button which gave an automatic injection—instead of having all injections made by the doctor. Afterwards these women did not say that they had less pain than other women in childbirth, but they did use considerable less of the drug.
J. Atkins, a dental surgeon, has observed a similar phenomenon. As part of their efforts to make dentistry painless, Atkins and researchers at Aston University in Birmingham offered patients a switch they could flip to turn off the dentist's drill whenever they chose. But, after trying the switch on 50 patients Atkins gave up; none of the patients had ever flipped the switch.
Perhaps the extra endurance was because the Aston team also use other methods to make dentistry painless. Apparently few other dentists are so considerate. The end result, according to the Birmingham survey, is that British people avoid going to the dentist, with the consequence that almost 30% of people in England and Wales have lost all their teeth, and more than seven out of ten have lost at least six teeth. Less than half of the public pay regular visits to the dentist. To find out why, Atkins and psychologist Cumberbatch interviewed a sample of patients attending a dental hospital. The most common reason people gave for not having dental check-ups were fear and pain.
By using a little care and taking time to explain what will happen, Atkins feels, dentists could overcome these fears. There are techniques for giving injections without pain, and a "calm unhurried approach" to drilling can make that painless, too.
Sadly, few dentists seem to take much trouble with their patients. "I am not nervous when I go to the dentist, and I do not have any pronounced sympathy for those who are, " said one dentist. "I tend to take the point of view that they are being unreasonable at my expense."
The passage most possibly comes from______.
A．a medical textbook
B．a psychology textbook
C．a popular magazine
D．a serious magazine

Aristotle, the Greek philosopher, summed up the four chief qualities of money 2,000 years ago. It must be lasting and easy to recognize, to divide, and to carry about. When we think of money today, we picture it either as round, flat pieces of metal which we call coins, or as printed paper notes. But there are still parts of the world today where coins and notes are of no use .A traveler there might starve if he had none of the particular ‘ local money ’.
Among isolated peoples ,who are not often reached by traders from outside ,commerce usually means barter ,which is a direct exchange of goods .Perhaps it is fish for vegetables or meat for baskets .For this kind of simple trading, money is not needed ,but there is often something that everyone wants ,such as salt to flavor food, shells for necklaces ,or iron and copper to make into tools. These things — salt ,shells or metals — are still used as money in out-of-the-way parts of the world today.
Salt may seem rather a strange material to use as money ,but in countries where the food of the people is mainly vegetables ,it is often an absolute necessity .Cakes of salt ,stamped to show their value ,were used as money in Tibet until recent times, and they can still buy goods in parts of Africa.
Cowrie seashells have been used as money at some time or another over the greater part of the Old World. These were collected mainly from the beaches of the Maldive Islands in the Indian Ocean ,and were traded to India and China. In Africa ,cowries were traded right across the continent from East to West .Four or five thousand went for one Maria Theresa dollar ,an Australian silver coin which was once accepted as currency (货币) in many parts of Africa.
Metal was used as money in many parts of the world .Iron ,in lumps ,bars or rings is still used in many countries instead of money .It can either be exchanged for goods ,or made into tools or weapons. The early money of China ,apart from shells ,was of bronze ,often in flat ,round pieces with a hole in the middle ,called ‘ cash ’.The earliest of these are between three thousand and four thousand years old — older than the earliest coins of the eastern Mediterranean.
Nowadays ,coins and notes have supplanted nearly all the more picturesque forms of money ,and although in one or two of the more remote countries people still store it for future use ,primitive money will soon be found only in museums.
