46、根据以下内容回答46-65题：
It has been shown that children who smoke have certain characteristics.Compared with non.smokers they are more rebellious，their work becomes worse as they move up school，they are more likelv to leave school early，and are more often delinquent and sexually premature.Manv of these features can be summarized as anticipation of adulthood.
There are a number of factors which determine the onset of smoking，and these are largely psychological and social.They include availability of cigarettes，curiosity，rebelliousness，appearing tough，anticipation of aduhhood，social confidence，the example of parents and teachers，and smoking by friends and older brothers and sisters.
It should be much easier to prevent children from starting to smoke than to persuade adults on giving up the habit once established，but in fact this has proved very difficult.The example set up by people in authority，especially parents，health care workers，and teachers，is of Drime importanee.School rules should forbid smoking by children on the premises.This rule has been introduced at Summerhill School where I spent my school days.
There is,however，a risk of children smoking just to rebel against the rules，and even in those schools which have tried to enforce no smoking by physical punishment there is as much smoking as other schools.Nevertheless，banning smoking is probably on balance beneficial.Teachers should not smoke on school premises，at least not in front of childr‘en.
In the passage the author puts emphasis on__________ .
A.the effect of smoking among children
B.the reason why children start smoking
C.the difficulty in preventing.children from smoking
D.the measures to ban smoking among children
