Passage One
Can animals be made to work for us？ Some scientists think that one day animals may be trained to do a number of simple jobs that are now done by human beings.
They point out that at a circus， for example， we may see elephants， monkeys， dogs and other animals doing quite skillful things. Perhaps you have seen them on the television or in a film. If you watch closely， you may notice that the trainer always gives the animal a piece of candy or a piece of fruit as a reward. The scientists say that many different animals may be trained to do a number of simple jobs if they know they will get a reward for doing them.
Of course， as we know， dogs can be used to guard a house， and soldiers in both old and modem times have used geese to give warning by making a lot of noise when a stranger or an enemy comes near. But it may be possible to train animals to work in factories. In Russia， for example， pigeons which are birds with good eyesight， are being used to watch out for faults in small steel balls that are being made in one factory. When the pigeon sees a ball which looks different from others， it touches a steel plate with its beak. This turns on a light to warn people in the factory. At the same time a few seeds are given as a reward. It takes three to five weeks to train a pigeon to do this and one pigeon can inspect 3 000 to 4 000 balls an hour.
Apes have been used in America in helping to make cars， and scientists believe that these large monkeys may be one day gather crops and even drive trains.

根据以下内容回答题：
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
