Ceremonial bathing（仪式性的沐浴）has existed for thousands of years and has many forms, one of which is the sauna. The Finns have perfected the steam bath,or sauna,which may be taken, usually in an enclosed room,by pouring water over hot rocks or as a dry heat bath.The Japanese, Greeks,Turks and Russians as well as Native Americans have forms of the sweat bath in their bathing rituals.Dry heat and steam baths had advocates in ancient Rome and pre-Columbian Americans used sweat lodges.
The earliest saunas were probably underground caves heated by a fire that naturally filled with smoke as chimney making was unknown at that time.A fire kept in a fire-pit would heat the rock walls of the cave.After reaching full heat,the smoke was let out of the cave and the stones would retain heat for several hours.A few people today say that the smoke sauna,"savusauna"is the only true sauna experience and that all saunas should have at least a background odor（气味）or smoke. Today most saunas use electric stoves,although gas and wood-burning stoves are available.
Saunas are relaxing and stress relieving. Those with muscle aches or arthritis（关节炎）may find that the heat relaxes muscles and relieves pain and inflammation（炎症）.Asthma patients find that the heat enlarges air passageways of the lung and facilitates breathing. Saunas do not cure the common cold but they may help to alleviate congestion（减轻胸闷感）and speed recovery time. The body's core temperature usually rises 1—2 degrees while in the sauna,thus imitating a slight fever. The sauna could be considered to follow the old saying"feed a cold,starve a fever".The regular use of a sauna may decrease the likelihood of getting a cold in the first place.
Sauna is good for your skin as the blood flow to the skin increases and sweating occurs.Adults sweat about 2 pounds of water per hour on average in a sauna. A good sweat removes dirt and grime （污垢；尘垢）from pores and gives the skin a healthy glow. The loss in water weight is temporary as the body's physiological mechanisms will quickly restore proper volumes.The cardiovascular system（心血管系统）gets a work out（运动，锻炼）as the heart must pump harder and faster to move blood to the surface for heat exchange.Heart rate may increase from 72 beats per minute on average to 100一150 beats per minute.
A normal heart can handle these stresses but those with heart trouble wishing to begin to use a sauna should seek a doctor's advice. The elderly and those with diabetes（糖尿病）should check with their doctor prior to beginning to take saunas.Pregnant women should not take saunas,particularly in the first three months. Indeed,everyone just starting out should take short sessions（做某事的一段时间）at first to become accustomed to this type of bath. Who are advised not to take a sauna?
A.Elderly people
B.Pregnant women
C.People with heart trouble
D.All of the above

A Very Slow Ride

The surface of the earth may seem very stable to you.But you might be amazed if you
knew some of the things that are going on under that surface.
The earth has an outer shell of rigid pieces called tectonic plates（地壳构造板块）.The
plates include both ocean floor and dry land.Some have whole continents on top of them.
The continents on top of the plates are just going along for a slow ride,moving only about
four inches per year. But even this small movement causes three types of big interactions.
One type is ocean ridges.These ridges develop in places where two plates are moving
away from each other. As the plates separate , hot magma（岩浆）flows up to fill the
space. New crust（地壳）builds up on the plate boundaries and causes ocean ridges.
These ridges form long mountain ranges,which only rise above the ocean surface in a few
places.
Another type of reaction-trenches-occurs between two plates that are moving toward
each other.As the plates meet,one bends downward and plunges underneath the other.
This forms deep ocean trenches.The Marianas Trench off Guam in the western Pacific
Ocean has a depth of more than 36,000 feet.This is the lowest point on the ocean floor.
If the leading edges of the two colliding plates carry continents,then the layers of rock in the
overriding plate crumple（变皱）and fold. A plate that carried what is now India collided with
the southern edge of the plate that carried Europe and most of Asia.This caused the
Himalayas,the world's highest mountains.
The third reaction is transform faults（转换断层）.These faults occur where two plates
that are traveling in opposite directions slide past each other.Severe earthquakes can
occur. The San Andreas Fault in California is a good example of this type of movement. This passage is mostly about
A.effects of movements of the earth's plates.
B.different types of continents.
C.the Marianas Trench.
D.transform faults.
