Plastics is the term commonly used to describe a wide range of synthetic or semi-
synthetic materials that are used in a huge and growing range of applications. Everywhere
you look, you will find plastics. We use plastic products to help make our lives cleaner,
easier, safer and more enjoyable. We find plastics in the clothes we wear, the houses we live
in, and the cars we travel in. The toys we play with, the televisions we watch, the computers
we use and the DVDs we watch all contain plastics.
Plastics are organic materials, just like wood, paper or wool. The raw materials used to
produce plastics are natural products such as cellulose, coal, natural gas, salt and, of course,
crude oil. Plastics have become the modern material of choice because they make it possible
to balance today’s needs with environmental concerns.
The term “plastic” is derived from the Greek word “plastikos”, meaning fit for moulding.
This refers to the material’s malleability, or plasticity during manufacture, which allows it to be
cast, pressed, or extruded into a variety of shapes - such as films, fibres, plates, tubes,
bottles, boxes, and much more.

Saving the Environment: One Home at a Time

Pollution can be seen not only throughout the world, but also in our own homes. It comes from household chemicals, the amount of water people use and the waste people produce and throw away. What can be done to stop this pollution? Surprisingly, a person can help save the environment by doing simple things.

First, we need to recycle, which allows products to be used over and over again. Recycling can also reduce the number of trees cut down to produce paper products. It takes very little effort. It is not hard to place plastic and glass bottles, aluminum cans and paper in a bin. Anyone can do it.

Second, we need to watch the amount of water used at home. It can be conserved by taking short showers instead of baths, repairing leaky faucets, using the dishwasher or washing machine only when fully loaded, or simply turning the faucet off while brushing your teeth.

Third, we need to reduce waste. We need to recycle whenever possible, but should also try to use this waste effectively. For example, grass clippings and food scraps can be made into compost for

plants. The average person produces 4.3 pounds of waste every day, but we can reduce that amount by recycling and reusing.

If we do our part in our own homes, we can help keep the planet from becoming more polluted.

1. Pollution is caused from the following sources except .

A. water in rivers B. water from households

C. wastes D. house chemicals

2. Recycling can help us .

A. never cut down trees B. produce more paper products

C. place garbage bins easily D. use products again and again

3. In order to save water, we can do all of the following things except .

A. fully use the washing machine

B. repair leaky faucets

C. take short showers instead of baths

D. turn the faucet off while brushing your teeth

4. Recycling helps to reduce waste because .

A. plants need to develop

B. waste can be recycled and reused

C. a person can do it in his home

D. an average man produces compost for plants

5. The word “It” in paragraph 2 refers to .

A. cutting down B. the number

C. recycling D. effort

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

7. Read the passage about some future predictions and answer the questions. Circle A, B, or C.

Dr Pearson, a futurologist believes in 2045 buildings will be made from concrete plastics and shape-changing materials that can heal themselves and the builders will have super-strength skeletons creating half-man, half-machine workers. There will be a need for new kinds of elevators using magnetic systems. 

By mid-century, buildings will be miles tall and some may be so large that their capacity enables them to function as small cities in their own right. As these buildings rise through the clouds, windows will be replaced by reality virtual screens so people can choose any view they like.  

However, lack of exposure to pathogens will cause more allergies. Due to health concerns, scents, candles, incense are also likely to be more strongly regulated, added Dr Pearson.

You may use the telephone every day but how much do you know about it? The telephone was invented by Alexander Bell in 1876. Bell was born in Scotland in 1847. Later he went to live in the US. Alexander Bell was always interested in sound. He wanted to be able to send sound through a wire. He had a workshop in his house in America and did many experiments there. One day, while he was doing an experiment in his workshop, he was careless and spilt some burning liquid onto his clothes. Talking into his telephone, Bell said: “Mr. Watson, I want you to come over here immediately, please.” His assistant, Watson, was in another room far away from the workshop. However, he heard Bell clearly on his own telephone. Quickly, he ran to Bell’s workshop. “Mr Bell, I heard every word you said!” Watson shouted excitedly. Bell finally succeeded. He had invented the first telephone. Later other inventors made better ones.
