Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 36 to 42.
Environmental pollution is one of the impacts of human activities on the Earth. Pollution occurs when pollutants contaminate the natural surroundings; which brings about changes that affect our normal lifestyles adversely. Pollution disturbs our ecosystem and the balance in the environment. Pollution occurs in different forms; air, water, soil, radioactive, noise, heat/ thermal and light Let us discuss the causes and effects of air pollution on mankind and the environment as a whole.
Air pollution is the most prominent and dangerous form of pollution. It occurs due to many reasons. Excessive burning of fuel which is a necessity of our daily lives for cooking, driving and other industrial activities; releases a huge amount of chemical substances in the air every day; these pollute the air. Smoke from chimneys, factories, vehicles or burning of wood basically occurs due to coal burning; this releases sulphur dioxide into the air making it toxic.
The effects of air pollution are evident too. The increase in the amount of CO2 in the atmosphere leads to smog which can restrict sunlight from reaching the earth. Thus, preventing plants in the process of photosynthesis. Gases like sulfur dioxide (SO2) and nitrogen oxide (NO) can cause acid rain.
The decrease in quality of air leads to several respiratory problems including asthma or lung cancer. Chest pain, congestion, throat inflammation, cardiovascular disease, respiratory disease are some of diseases that can be caused by air pollution.
The emission of greenhouse gases particularly CO2 is leading to global warming. Every other day new industries are being set up, new vehicles come on roads and trees are cut to make way for new homes. All of them, in direct or indirect way lead to increase in CO2 in the environment. The increase in CO2 leads to melting of polar ice caps which increases the sea level and pose danger for the people living near coastal areas.
Ozone layer is the thin shield high up in the sky that stops ultra violet rays from reaching the earth. As a result of human activities, chemicals, such as chlorofluorocarbons (CFCs), were released into the atmosphere which contributed to the depletion of ozone layer.
Which of the following can be inferred from the passage?
A. The more modern our lives become, the more serious the pollution is
B. People can control air pollution soon in the future
C. Only air pollution is dangerous and has a negative impact on humans and the environment
D.
C
O
2
is the cause of the depletion of ozone layer
Choose the best answer (A, B, C or D).
1 unless most of us replace coal fuel with gas fuel ,we can hardly centrol air pollution
->Air pollution__can hardly be controlled if most of us don't replace coal fuel with gas fuel._________
2because the airport is located near our neighborhood ,we must suffer from noise pollution every day
->we wouldn't__suffer from noise pollution every day if the airport weren't located near our neighborhood.________
3 this ship pollutant especially oilspills ,is one of main causes of the ocean pollution Therefore, we need to reduce it
->If we____reduce theis ship pollutant especially oilspills, we can reduce ocean pollution______________________remarkably
4present, level of air pollution shown in the Air Quality.Index might surprise you
->If yoy check(checked)_???_____________
5thomas expects for a amount of money to movie to another place to stay away the noisy industrial zone
->If thomas moves to another place to stay away the noisy industrial zone, he will expect for an amount of money.
6Ice melting is considered as a redult of the global warminjg we cause
->we couldn't/won't have to wory about global warming if there weren't ice melting.
1 unless most of us replace coal fuel with gas fuel ,we can hardly control air pollution
->Air pollution can hardly be controlled unless most of us replace coal fuel with gas fuel.
2because the airport is located near our neighborhood ,we must suffer from noise pollution every day
->we wouldn't have suffered from noise pollution everyday if the air port hadn't located near our neighborhood.
3 this ship pollutant especially oilspills ,is one of main causes of the ocean pollution Therefore, we need to reduce it
->If we reduce this ship pollutant especially oilspills, the ocean pollution will reduce remarkably
4present, level of air pollution shown in the Air Quality.Index might surprise you
->If you check(checked)the level of air pollution at present by the Air Quality Index, you might be suprised.
