Cigars instead

Smoking one or two cigars a day doubles the risk of cancers of the lip，tongue，mouth and throat，according to a government study．
Daily cigars also increase the risk of lung cancer and cancer of the esophagus，and increase the risk of cancer of the larynx(voicebox) sixfold，say researchers at the National Cancer Institute in Bethesda，Maryland．
In addition，the report revealed that smoking three or four cigars a day increased the risk of oral cancer to 8.5 times the risk for nonsmokers and the risk of esophageal cancer by four times the risk of nonsmokers．

The health effects of smoking cigars is one of eight sections of the article“Cigars：Health Effects and Trends．”The researchers report that，compared with a cigarette，a large cigar emits up to 90 times as much carcinogenic tobacco．specific nitrosamines．
“This article provides clear and invaluable information about the disturbing increase0 in
cigar use and the significant public health consequences。for the country，”said Dr．Richard
Klausner，director of the National Cancer Institute，in a statement．
“The data are clear—the harmful substances and carcinogens in cigar smoke．1ike
cigarettes，are associated with。the increased risks of several kinds of cancers as well as heart and lung diseases，”he added．“In other words，cigars are not safe alternatives to cigarettes and may be addictive．”
“To those individuals who may be thinking about smoking cigars,our advice is—don’t．To those currently smoking cigars，quitting is the only way to eliminate completely the cancer，heart and lung disease risks，”warned Klausner．
According to a National Cancer Institute press release, there haven’t been any studies on the health effects on nonsmokers at cigar social events．but“…a significant body of evidence clearly demonstrates an increased lung cancer risk from secondhand smoke．’’

Some things we know about language

Many things about language are a mystery, and many will always remain SO．But some
things we do know．
First，we know that all human beings have a language of some sort．There is no race of men anywhere on earth so backward that it has no language，no set of speech sounds by which the people communicate with one mother．Furthermore，in historical times，there has never been a race of men without a language．
Second，there is no such thing as a primitive language．There are many people whose
cultures are undeveloped，who are，as we say，uncivilized, but the languages they speak are not primitive．In all known 1anguages we can see complexities that must have been tens of thousands of years in developing．
This has not always been well understood；indeed, the direct contrary has often been stated．Popular ideas of the 1anguage of the American Indians will illustrate．Many people have supposed that the Indians communicated in a very primitive system of noises．study has proved this to be nonsense．There are，or were，hundreds of American Indian languages，and a11 of them turn out to be very complicated and very old. They are certainly different from the languages that most of us are familiar with，but they are no more primitive five than English and Greek．
A third thing we know about language is that all languages are perfectly adequate．That is, each one is a perfect means of expressing the culture of the people who speak the language．
Finally, we know that language changes．It is natural and normal for language to change；
the only languages which do not change are the dead ones．This is easy to understand if we look backward in time．Change goes on in all aspects of language．Grammatical features change as do speech sounds，and changes in vocabulary are sometimes very extensive and may occur very rapidly．Vocabulary is the least stable part of any language．
词汇：
race／n．种族
primitive／adj．原始的
uncivilized／adj．不开化的，落后的
complexity／n．复杂性，复杂现象
nonsense／n．胡说，没有根据的话
extensive／adj．广泛的
vocabulary／n．词汇
