The Earth Day comes from the idea of a former US politician Gaylord Nelson. He was worried about the world pollution, and the health of plants and animals. In 1969, he decided that the world should have a special day to teach people about how to make environment better. His idea became popular and on 22 April 1970 the first Earth Day was celebrated. Since then, environmentalists have used the day to educate people about their roles in protecting our planet. Earth Day finally became a global celebration around the world. On this day, people come together to talk about global warming, protecting rare animals and saving energy sources. Question 19: The word “their” in the second paragraph refers to ______.

A: Dr. Nelson’s

B: politicians’

C: people’s

D: environmentalists’

1. Read the passage and complete the sentences. Circle A, B, or C.

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.

Rain forests cover less than six percent of the earth’s area, but they have 100,000 kinds of all the kinds of plants on the earth. Three-fourths of known kinds of plants and animals call the rain forest their home. Twenty percent of our different kinds of medicine comes from rain forests. The glues on an envelope and in shoes come from tropical plants. Rain forests provide materials for hundreds of other products.

Rain forests are also very important to the world’s climate. The Amazon rain forest alone receives about thirty to forty percent of the total rainfall on the earth and products about the same percentage of the world oxygen. Some scientists believe that the decreasing size of rain forests will affect the climate on the earth, making it uncomfortable or even dangerous for life.

Saving rain forests is an international problem. One country, or even a few countries, cannot solve the problem alone. The nations of the world must work together to find a solution before it is too late.

How many known kinds of plants and animals call the rain forests their home?

A. 4/3

B. 3/4

C. 40/3

D. 3/40

Plans grow(46) almost every part of the world. We see(47) plants as flowers, glass, and tree nearly every day. Plants grow high on moutaintops, far in the oceans, and in many deserts and(48) regions

Without plants, there could be not life on earth. Man could not live without air of food and so he could not live without plants. The oxygen in the air we breathe comes from plants. The food we eat also comes from plants or from animals that eat plants. We build houses and make many(49) products from lumber cut from trees. (50) of our clothing is made from the fitbers of the cotton plants.

Scientists belive there are more than 350,000 species of plants, but no one knowns for(51). Some of the smallest plants, called diatoms, can be seen only with a(52). A drop of the water may hould as many as 500 diatoms. The largest living things are the giant sequoia trees of California. Some of them stand more than 290 feet high and measure over 30 feet wide

Scientist(53) all living things into two main groups - plants and animals. It is usually easy to tell the two(54). Almost all kinds of plants stay in one place, but nearly all species of animals move about under their own power. Most plants make their own food from air, sunglight, and water. Animals cannot make their own food. The basic units of all life, called cells, are also different in plants and animals. Most plants have thick wall that(55) a material called cellulost. Animal cells dl not have this material.

Read the passage and check (ü) whether the following statements are true (T) or false (F).

Energy makes change; it does things for us. It moves cars along the road and boats over the water. It bakes a cake in the oven and keeps ice frozen in the freezer. It plays our favourite songs on the radio and lights our homes. Energy makes our bodies grow and allows our minds to think. Scientists define energy as the ability to do work. People have learned how to change energy from one from one form to another so that we can do work more easily and live more comfortably.

All forms of energy are stored in different ways, in the energy sources that we use every day. These sources are divided into two groups – renewable and nonrenewable. Renewable energy source is an energy source that can be replenished in a short period of time. Nonrenewable energy source is an energy source that we are using up and cannot recreate in a short period of time.

Renewable energy sources include solar energy, which comes from the Sun and can be turned into electricity and heat. Wind, geothermal energy from inside the Earth, biomass from plants, and hydropower and ocean energy from water are also renewable energy sources.

However, we get most of our energy from nonrenewable energy sources, which include the fossil fuels – oil, natural gas, and coal. They’re called fossil fuels because they were formed over millions and millions of years by the action of heat from the Earth’s core and pressure from rock and soil on the remains of dead plants and animals. Another nonrenewable energy source is the element uranium, whose atoms we split (through a process called nuclear fission) to create heat and ultimately electricity.

Question: Most of our energy we use every day comes from renewable energy sources.

A. True

B. False

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.

There are three valid arguments to support the preservation of endangered species. An aesthetic justification contends that biodiversity contributes to the quality of life because many of the endangered plants and animals are particularly appreciated for their unique physical beauty. The aesthetic role of nature in all its diverse forms is reflected in the art and literature of every culture, attaining symbolic status in the spiritual life of many groups. According to the proponents of the aesthetic argument, people need nature in all its diverse and beautiful forms as part of the experience of the world.

Another argument that has been put forward, especially by groups in the medical and pharmacological fields, is that of ecological self–interest. By preserving all species, we retain a balance of nature that is ultimately beneficial to humankind. Recent research on global ecosystems has been cited as evidence that every species contributes important or even essential functions that may be necessary to the survival of our own species. Some advocates of the ecological argument contend that important chemical compounds derived from rare plants may contain the key to a cure for one of the diseases currently threatening human beings. If we do not protect other species, then they cannot protect us.

Apart from human advantage in both the aesthetic and ecological arguments, the proponents of a moral justification contend that all species have the right to exist, a viewpoint stated in the United Nations World Charter for Nature, created in 1982. Furthermore, if humankind views itself as the stewards of all the creatures on Earth, then it is incumbent upon human beings to protect them, and to ensure the continued existence of all species. Moral justification has been extended by a movement called "deep ecology", the members of which rank the biosphere higher than people because the continuation of life depends on this larger perspective. To carry their argument to its logical conclusion, all choices must be made for the biosphere, not for people.
