Guide to answer

first. diesel vehicle (diesel engine vehicle)

2. melting of the Arctic (melting ice in the Arctic)

3. soot (soot, coal dust)

2. Task 2 Unit 3 Grade 12 Reading

Read the following article about soot pollution. Choose the appropriate heading (ad) for each paragraph. (Read the following article about coal dust pollution. Choose the appropriate title (ad) for each paragraph.)

a. Soot and global warming (Coal dust and global warming)

b. The effect of soot on human health (Effects of coal dust on human health)

c. The origin of soot (The origin of coal dust)

d. Ways to reduce soot emissions (How to reduce coal dust emissions)

Nowadays we know a lot about the link between carbon dioxide (C02) emissions and global warming. However, we seem to be unaware of one very dangerous pollutant, soot also called black carbon.

first.________

Soot comes from the incomplete combustion or coal, oil, wood and other fuels. In other words diesel engines, vehicle exhaust pipes, farming machines, construction equipment, or simply fires in grills, fireplaces, and stoves are potential sources of soot. It appears in our daily life and can easily affect every one of us.

2._______

Soot like all black things absorb sunlight and heats up the atmosphere. According to recent research, it is the second most damaging greenhouse gas after C02, and twice as harmful to the climate. Although black carbon remains in the atmosphere for no more than seven days it is particularly damaging to frozen areas. Soot emissions might be responsible for the quick melting of the Arctic. Controlling black carbon can help to slow down global warming.

3._______

Soot does not only have an impact on global warming and climate change, but is also unhealthy. A soot particle is very tiny – smaller than dust and mould, and about 1/30 the width of a human hair. It can easily go into our blood and lungs via the nose and throat. As a result, breathing in the tiny particles car cause asthma attacks, heart disease, bronchitis and many other respiratory illnesses.

4._______

Large quantities of man-made soon enter the atmosphere every year. The effects are most damaging regionally, especially in South and East Asia, Latin America and parts of Africa. In developing countries, reducing soot emissions can be achieved by replacing traditional stoves with clean, alternative fuel cookers and heaters. Installation of filters to remove black carbon from diesel vehicles can also reduce soot. Changing to electric or hydrogen vehicles will also reduce the impact on the environment.

In conclusion, reducing black carbon will have immediate benefits in slowing down global warming and the melting of the Arctic snow and ice. It would also prevent many soot-related deaths and illnesses.

Translation

Today we know a lot about the connection between Co2 emissions and global warming. However, we seem to be unaware of a very dangerous pollutant, coal dust, also known as black carbon.

first. Origin of coal dust.

Coal dust comes from the incomplete combustion of coal, oil, wood and other fuels. Among other sources such as, diesel engines, vehicle exhausts, agricultural machinery, construction equipment, or fires in ovens, fireplaces, and stoves are potential sources of han buijt. It shows up in our daily lives and can easily affect all of us.

2. Coal dust and global warming

Coal dust is like black things that absorb sunlight and heat up the atmosphere. According to recent research, it is the second most harmful greenhouse gas after CO2, and is twice as harmful to the atmosphere. Although black carbon stays in the air for no more than 7 days, it is particularly susceptible to freezing regions. Soot emissions may be responsible for melting Arctic ice. Controlling black carbon can help slow global warming.

3. Effects of coal dust on human health

Coal dust not only has an impact on global warming and climate change, but is also harmful to health. A very small particle of coal dust is smaller than dust and mold, and only 1/30 the width of a human hair. It can easily enter our bloodstream and lungs through the nose and throat. As a result, inhaling small particles can cause asthma, heart disease, bronchitis and many other respiratory ailments.

4. How to reduce coal dust emissions

Every year, a large amount of man-made coal dust enters the atmosphere. These effects are most damaging to certain regions, particularly Southeast Asia, Latin America and parts of Africa. In developing countries, coal dust reduction can be achieved by replacing traditional stoves with clean stoves and fireplaces. Installing filters to remove black carbon from diesel engines can also reduce coal dust. Changing to electric or hydrogen vehicles would reduce the impact on the environment.

In short, reducing black carbon would have immediate benefits in reducing global warming and the melting of Arctic snow and ice. It will also prevent many deaths and illnesses associated with coal dust.

4. Task 4 Unit 3 Grade 12 Reading

Discuss with a partner. Are soot emissions a problem in your community or in Vietnam in general? (Discuss with a friend. Is coal dust a problem in your community or in Vietnam in general?)

Guide to answer

Soot emissions are a problem in Vietnam in general. Because of some reasons: (Soot waste is a problem in Vietnam in general for a number of reasons)

5. Practice Task 1

Read the following text and choose the best answer for each question. (Read the text below and choose an answer for each question.)

If you want to make your school green, think beyond your classrooms. Here are some suggestions that are all easy and simple to follow, and can make a big difference in reducing your carbon footprint and creating a sustainable community.

One of the places where both teachers and students often spend some of their time is the library. An eco-friendly reading space is likely to create a favourable impression on library users, and bring some significant educational benefits. For example, you can install energy-saving products like fans instead of air-conditioners which consume a lot of energy. You can also use biodegradable dust cloths or old T-shirts to clean the environment. In addition, to raise public awareness, allocate a clearly visible space on the noticeboard for everyday green tips like ‘Let others reuse your book’.

Sporty students may prefer to spend more time in the swimming pool than in the library.

Therefore, keeping this place safe and green v also help to raise their environmental awarem Remember that chlorinated pool water may cause red eyes and itchy skin to some people if they spend much time in the pool. An ideal alternative would be a salt-water pool, which can be naturally clean and economical. In cas< warm water is required, think of solar heating save the environment as one pool with gas or electric heater may emit tons of carbon dioxide each year.

Finally, focus on the school gym, which is perhaps the most interactive and exciting pla for all school staff. Think of installing low-flov taps and showers to save gallons of water per minute and energy-saving lights to cut the cost of electricity. Moreover, make sure that tl airflow pathways are clear and free of mould, mildew and other allergens.

first. What do you think is the best title for the text? What do you think is the most suitable title for the text?

A. How to make your community green.

B. Ways to raise students’ awareness of being environmentally friendly.

C. How to make your school more sustainable.

2. For which of these places does the writer NOT offer any green suggestions?

A. Classrooms. B. Gymnasium. C. Thư viện.

3. Which energy-saving product is NOT mentioned in the text?

A. Fans. B. Solar heating. C. Energy-efficient windows.
