Unit 7: Pollution - Looking back and project

Thưa thầy/cô. Em có vấn đề chưa hiểu, em xin đặt câu hỏi như sau:
Đây là bài thi nói của em. Em mong thầy cô góp ý ạ. Em cảm ơn 1/Choose one of the type of pullution(air/water/soil pollution) and talk about its causes, effects and solutions. =>The type of pollution I choose is air pollution because it is one of the most concerning issues for our planet and mankind. There are many causes of air pollution such as wildfires, dust, and volcano eruptions. But mostly, our human actions cause pollution from things like power plants that burn fossil fuels, fertilizers and animal waste from farming, wood- stoves, driving cars, flying planes, and more. Regarding effects, firstly, people can suffer from many respiratory diseases. Second, people can't live long because of a lack of oxygen. And last, it will destroy the ozone layer and make it easier for the Sun's rays to penetrate the Earth. For solutions, I think we can use public transport, reduction of forest fires and smoking, plant trees, install pollution control devices, people need to raise their awareness, contribute to protecting the environment and protect us. 2/ Imagine you are awarded a scholarship to attend an English language course abroad. Which country ( America / Britain / Australia..) would you like to go to? Why? =>If I have a chance to attend an English language course abroad with scholarships, I would like to go to Australia. Because many reasons. Firstly, The Australian education system is considered one of the best education systems in the world, for both domestic and international students. Secondly, there are so many virtual living places here such as Sydney Opera House, a very popular place when we talk about Australia. Thirdly,, you know, I’m a food lover, and Australian cuisine is very diverse and suits my taste, especially Chicken Parmigiana. Finally, the people here are very friendly, funny, simple and generous. 3/ What preparations do you think should be made for a typhoon? =>I think before the typhoon, we have to do a lot to protect members of the family and our house. Firstly, we need to keep important documents in a safety deposit box or a bolted safe. Secondly, prepare an emergency kit such as extra batteries, non-perishable food, bottled water, cash, blankets, clothing and personal hygiene items. Thirdly, identify a shelter in your house. Fourthly, fill your car’s gas tank and charge your cell phone. Finally, trim large trees and shrubs and bring all outside patio furniture indoors. 4/ What type of communication do you like? Why ? =>My favorite type of communication is video chat for many reasons. Firstly, as we know, the number of people infected with COVID- 19 in Vietnam is always increasing day by day, we must limit going out as little as possible to protect ourselves, so video chatting is the best choice. Secondly, we can meet users from all over the world with different cultures and languages. Finally, can reduce a lot of costs and travel time. For these reasons, I choose video chatting is the best type of communication that I like.
