Computer games have become more and more popular in many cities and towns．In order to get more money，a lot of small shops have been changed into computer game houses along the streets．These places are always crowded with people．People spend a lot of money playing computer games．Some people play in the computer game houses for hours and hours．For school boys，things are even worse．When school is over，they rush into the computer game houses near their school．Some of them aren't interested in their lessons any more．They spend all their free time in playing computer games．Sometimes they don't eat or sleep for several days．This is a serious problem．Something has to be done to stop it．But the most important thing is that young people must be far away from computer games．
1．In common with many countries，Britain has serious environmental problems．In 1952，more than 4，000 people died in London because of the smog．The governmentintroduced new laws to stop smog from coal fires and factories and thesituation improved a lot．
Today，London is much cleaner but there is a new problem：smog from cars．In December 1991，there was very little wind in London and pollution increased a lot．As a result，about 160 people died from pollution in just four days．
Part of the problem is the new"out of town"shopping centers．In the past，people often walked to shops near their home or went by bus．Now，many people drive to the new shopping centers．As a result，the small shops have disappeared and more people have to travel to do their shopping．
Critics（评论员） say that Britain needs better and cheaper public transport．Transportin Britain is very expensive．An early morning train trip from Glasgowto London（about 600km） can cost about 100 pounds，for example．A short 15-minute bus trip can cost over 1.00 pound．
Many people are trying to reduce the use of cars in Britain．Some cities now have special bicycle paths and many people cycle to work．Some people also travel to work together in one car to reduce the pollution and the cost．
