Task 1: The diagram below describes how storm water is recycled in an Australian city.
The diagram provides a breakdown of stormwater harvesting in an unspecified Australian city. The initial impression from the diagram is that rainwater from drains undergoes various physical and chemical processes underground to become clean water which is stored and then reused on sunny days.
The process commences when stormwater runoff is collected from drains and then flows in pipes into an underground water recycling plant where it goes through four distinct treatment phases. Large wastes such as plastic and rubbish are discarded in the first phase, and smaller particles are later filtered out in the second phase. Microscopic impurities such as bacteria, viruses, molecules, and salt are then removed in the third and fourth phases.
Once purified, stormwater is chlorinated at 4mg/l, after which it is stored in a chamber. The process ends when the water, now safe for domestic use, is sent back to Australian households and reused on sunny days.
1. stormwater harvesting: tái sử dụng nước mưa
2. drain: cống
3. runoff: dòng chảy
4. distinct: riêng biệt
5. discard: loại bỏ
6. particle: phần tử
7. filter out: lọc ra
8. microscopic impurities: chất bẩn nhỏ không thể nhìn bằng mắt thường
Task 2: It is not necessary to travel to travel to other places to learn the culture of other people. We can learn just as much from books, films and the internet . Do you agree or disagree?
