H:Why was it so bad then?
BD:Well,Britain was one of the first industrial countries and factories and homes used lots of coal.When burnt,the coal produced harmful emissions which created lots of smog.In London,they also called the smog a “pea soup” because it was as thick as soup.
H:That sounds terrible! What problems did it cause?
BD:Smog caused many health issues and killed many people.The worst case happened in London in 1952.Over a few days when the smog was particularly bad,4,000 deaths were recorded.It was necessary to take immediate action.The UK government ordered people not to burn coal in their homes and forced factories to move away from city centres.

BD:Smog is harmful to everyone,especially to children,old people and those with heart or lung problems.We have to reduce smog and improve air quality for everyone’s health and wellbeing.We should replace coal with cleaner forms of energy,and we need to use new energy-efficient vehicles.We have the technology,but we must use and develop it.

Part Ⅳ
2.Litter is a big issue in our local community. We must deal with it because it is bad for local wildlife and it makes our community look terrible.
This mostly occurs in our local park. It is caused by people dropping food wrappers from the nearby fast food restaurant.
So far, we make sure the park is cleaned every day. We have added more rubbish bins in the park to make it easier for people to dispose of this waste. We also spoke to the fast food restaurant and asked them to encourage people to dispose of their waste properly.
There is a plan to add more bins and signs to inform people about the need to dispose of waste properly. We have also asked the restaurant to provide help in cleaning up their waste.
The issue has been dealt with well, but more work is needed. It is hard to deal with these issues because there is a never-ending source of waste as people will always need to buy food. In the future, the best solution would be to find alternative ways of packaging.
Part Ⅴ
The world we live in is becoming more and more intolerable because of environmental destruction. Haze weather is a typical example that is affecting our life. Besides, forest destruction results in serious soil erosion.
Serious as the problem seems, we can come up with some measures to deal with it. First of all, the environmental protection should be strictly put into effect. What’s more, every citizen should realise the seriousness of the problem and make efforts together to protect the environment.
I believe we can make our world a better place.
