Model 1
In the past twenty years，the amount of traffic onthe roads has greatly increased，and this has leadto many problems with traffic J ams and pollutionin inner city areas.Some countries have limitedthe use of cars in the inner city by charging feesor restricting the days on which people can driveint o the c i ty.This approach has some disadvantages.buton the whole it is a good solution to the problems of inner citytraffic.
Restricting car traffic in the city can make it very difficult forsome people to do their daily work.For example，movingquickly to meetings is very important for businessmen,and ifthey have no car,this will create problems for them.Inaddition,it is important for disabled people or for families withyoung children to access city services and they should be ableto drive their cars to the places where they need to go.Limiting the use of cars could create real inconvenience forsome citizens.
However,there are many advantages to this idea.Firstly，itgreatly reduces inner city pollution,both by reducing thenumber of cars and by encouraging the use of publictransport.This reduction in pollution benefits everyone wholives and works in the city.Secondly，it decreases trafficcongestion and makes it easier to move around the city.Thus，businessmenfind it quicker to get to their meetings and to visitother locations either by taxi or by bus or rail transport.（249words）

Recently，there has been a huge increase in the number of carson the roads.This has caused many problems with trafficcongestion in inner city areas.Some cities have tried to solvethis problem by building motorways underground or abovestreet level.This approach has some advantages but，ingeneral，it is not the best solution to the problems of inner citytraffic.
Elevated or underground motorway networks can reducecongestion by removing a lot of traffic from city streets.Thusit is much easier to travel around the city and quicker to getfrom one place to another.In addition,these new networks donot need to follow existing streets so they can take a moredirect route from one place to another,and this also makes iteasier to travel from place to place.
However，this approach has a lot of disadvantages.Firstly，itdoes nothing to reduce the number of cars in the city，and thismeans that it does not reduce pollution.In addition,it isdifficult to build motorway networks in an existing city.Consequently,it takes a long time and creates a lot ofcongestion while the new motorways are being built.Finally,the cars that come into the citv on these new networks have tocome back to street level once they reach their destination.Thismeansthattherewill stillbe alot of carsinthe city.（237words）

Model 3
Recently,the number of cars in the inner city has grownsignificantly，and this has led to many problems with parkingin inner city areas.Some countries have tried to solve thisproblem by building car parks around the inner city andproviding public transport to take people into the centralbusiness district.This approach has both advantages anddisadvantages for commuters.
Making car parks around the city can greatly reduce thenumber of cars in the city and make it much easier for peopleto travel long distances to work.They can drive their cars partway to work and then catch public transport to take them intothe inner city area.This avoids waiting in long traffic jams，and also reduces or eliminates parking problems.In addition,it could be cheaper for drivers to take public transport than topayhighinner cityparkingfees.
However，this plan needs to be carefully managed if it is goingto be effective.If many people use this system it could be agood idea，but if only a few people use it,it could be cosily toset up and not very effective in reducing congestion.
Therefore，public transport needs to be cheap，efficient andfast,so that it is quick and economical for drivers to get intothe city and to their workplaces.Secondly，there need to besufficient car parks on the outskirts of the city so thatbusinessmen and other commuters can easily find a park.
In conclusion,making car parks around the city has someadvantages for drivers，but it needs to be well planned andmanaged if it is to be effective.We all need to work together toreduce fossil fuel emissions and to make the inner city a morepleasant place to live and work.（302 words）
