Part 2&3  A place you visited where the air was polluted答案及解析_雅思口语练习「新东方雅思官方网校」

There are a few key ways of improving the air quality in a place. Firstly, imposing stricter regulations on factories and industries that pollute – and actually punishing them for not installing the correct filter systems or complying with the regulations. Secondly, reducing the amount of cars on the roads, and replacing the use of private cars with an increased use of public transportation. This is something that takes time and investments, but is most certainly worth it, for the benefit of the health of the coming generations, too. 

No, not in terms of air not really. Because cities have a lot of traffic, a lot of people and lot of industry surrounding them usually. The country towns usually just have a very agrarian economy which isn’t so polluting. It’s the industrial areas which cause the majority of the pollution in my country. So, no the countryside is generally less polluted, although there are some country towns that have factories on the outskirts, and they pollute the water table and the rivers, and because they are out in the country they sometimes ignore the regulations and escape punishments, so this can lead them to being quite polluting, too. 

Many have indeed. In fact, there are laws against this kind of thing, which have been passed a long time ago. It’s enforcing the laws and regulations which is the difficult thing, to be honest. The country is huge, and there are many cities and towns that have factories and heavy industry, and checking them all regularly and ensuring they consistently comply with the regulations is easier said than done! Sometimes the factory owners will say they are complying and get everything in shape for the environmental health checks. Then as soon as the inspectors have left, they go back to their same polluting ways – mainly because it’s cheaper to pollute than the keep all the filtration systems up to date and in working order. But yes, they are forced to reduce emissions as much as they can be forced, most certainly. 

Yes, there is generally more pollution now than in the past, especially in terms of air, water, and soil contamination. Industrialization, urbanization, and the increased use of fossil fuels have significantly contributed to higher levels of pollution. Modern conveniences like cars, factories, and plastic products have added pollutants that were not as prevalent in earlier times. However, it's worth noting that awareness and efforts to combat pollution have also increased, with many governments and organizations working to reduce emissions and promote sustainability. Despite these efforts, the overall level of pollution remains a significant concern today.
