小作文题目：
The diagrams below show the stages and equipment used in the cement-making process, and how cement is used to produce concrete for building purposes.
范文：
The diagram on the left illustrates the process by which cement is made whilst the diagram on the right shows us how concrete is made.
We can clearly see that the first stage in cement production is to put two substances –limestone and clay – through a crusher to create a powder. This powder then goes through a mixer and is then heated in a rotating heater. Once the powder has gone through the mixer and heater, it is ground and the cement is packed into bags.
The diagram on the right hand side tells us that concrete is a mixture of four ingredients in differing proportions. Cement makes up 15% of the mixture, water constitutes 10%, sand 25%, and gravel (i.e. small stones) 50%. These ingredients are mixed in a rotating concrete mixer to make concrete.
In summary, the production of cement and the production of concrete appear to be fairly simple processes
大作文题目：
Increasing the price of petrol is the best way to solve growing traffic and pollution problem. To what extent do you agree or disagree? What other measures do you think might be effective?
范文1——提高汽油价格不是解决日益增长的交通和污染问题的最佳方法
I disagree with the idea that increasing petrol prices is the best way to deal with traffic and pollution.
First of all, if petrol prices are increased, this will most likely lead to less petrol being used. This will make environmentalists happy, but it will also increase the cost of anything that uses petrol in its production or in transport – in other words, everything from plastic bags to computers. This is likely to lead to slower economic growth as less is bought and produced. Of course, there will be less traffic and there will be less pollution, but I do not think that the advantages of this outweigh the disadvantages.
I think that traffic problems can be dealt with by making drivers pay more to use certain roads at certain times. This has been very effective in London, where there is a charge for cars to use roads in the centre of London during working hours. As a result, traffic and pollution have decreased without harming the local economy.
Pollution could also be reduced by encouraging people to use energy more efficiently. The government could use and advertise campaign to show people that wasting energy by, for example, leaving electrical items on when they are not being used results in more pollution from electricity generation. In a similar way, the government could inform people about the financial benefits of insulating their homes.
To conclude, I believe that a rise in petrol prices would reduce pollution, but cause economic problems. Therefore, I think there are better alternative solutions available.
范文 2——提高汽油价格是解决日益增长的交通和污染问题的最佳方法
In this essay, I shall say why I believe that increasing petrol prices is the best way to reduce traffic and pollution problems and suggest other measures that might be effective.
If the price of petrol is increased, it is likely that people will try to use less of it. This should see a reduction in car use and therefore less pollution. Some people claim that this will have negative effects on the economy, but I disagree. People will almost certainly use less petrol in cases where using it is not very economic. For example, most drivers use their vehicles for short journeys which they could easily make on foot. It is these journeys that they are likely to stop making by car, not essential ones for their private lives or for work.
Another way of reducing traffic problems is to only allow certain cars to use the roads on given days. This method was used effectively in Beijing during the Olympic Games, reducing both traffic problems and pollution without any significant negative effects on the local economy. However, for a scheme like this to be successful, there needs to be a good public transport system.
Pollution can also be reduced by using other forms of energy generation. If we use these, we can make our economy better in the long term by investing in the technologies of the future. We will also improve the health of the population through having less pollution.
To summarise, I think that increasing petrol prices is the best way of reducing traffic and pollution problems and that there are other good ways of achieving this.。
