问题     Fossil fuels (e.g. coal, oil, natural gas) are the main sources of energy in many countries, but in some countries the use of alternative sources of energy is encouraged. Is it a positive or negative development?
选项
答案     I think that the focus on alternative, renewable sources of energy in some countries is an excellent idea and that countries that concentrate on fossil fuels seriously need to consider what they are doing. In this essay I shall explain why.
    One simple point is that fossil fuels are bad for our environment. The use of fossil fuels leaves behind particles in the air which can cause breathing disorders and pollute the natural world. The environment is naturally able to deal with a certain amount of pollution, but humans are now so numerous and our use of fossil fuels is so vast that this has now become impossible. As a result, w’e are faced with choosing renewable forms of energy or destroying our natural environment.
    Another point is that fossil fuels will eventually run out. This is a simple matter of logic. It takes millions of years for fossil fuels to form, yet it takes us far less time to use them. The problem is that nobody is sure about exactly when fossil fuels will run out. This is largely due to the fact that we don’t know where it all is.
    Some people claim that we can start using alternative energy sources when the fossil fuels run out, but this is not a real option. When fossil fuels really start running out, there will almost certainly be wars over the remaining supply and, perhaps more importantly, we will need a good supply of fossil fuels to create the energy required to construct wind turbines, solar panels and other equipment that alternative energy requires.
    To conclude, it seems obvious to me that we need to start developing alternative energy oh a large scale now, rather than waiting.
