Eco-tourism aims to be the most sustainable, environmentally friendly kind of tourism possible. The term ‘eco-tourism’ has been used (2) _______ 1983 to refer to vacations that are spent in natural environments without disturbing or damaging natural habitats. Profits from this type

of tourism generally help support the local economy and (3) _______ projects. Quite often, eco-tourism is done in remote parts of our planet which not many tourists have ever seen before. Therefore, it is also a great way to experience new cultures and original lifestyles. Unfortunately, (4) _______ eco-tourism tries its best to keep the adverse impact on our environment to a minimum, chances are that the local wildlife will still be disturbed to a certain extent. Let’s look at Kenya, where trips on safari are usually in the morning. This is also the time when lions go hunting. However, the eco-tourists (5) _______ many other animals away, meaning that lions in the area have to hunt in the hot, tiring hours of the day.

SAVE OUR NATIONAL PARKS

Governments have different rules that (1)_________ various national parks in the world for many reasons, one of which is to conserve and improve their natural beauty, wildlife and cultural heritage. For example, the United States’ Yellowstone National Park is famous for its deep gorges, grand canyons, active geysers and amazing waterfalls. The Kruger National Park in South Africa is (2)__________ to magnificent wildlife. In Tanzania’s Serengeti National Park, you can see leopards, zebras, gazelles, wildebeests and beautiful acacia trees.

In reality, the preservation of different national parks in the world is becoming much more difficult than ever because of many natural reasons, one of which is global warming. The rising temperature has put many national parks (3)_________ serious danger over the past 100 years. For example, Glacier National Park in Montana, USA, has lost 40% of its glaciers since 1966. In other words, it has become smaller, and many local species have become endangered because they have (4)_________ their homes. Consequently, the park conservation has been in trouble since then. In some marine national parks, global warming has also caused the sea temperature to (5) _______and negatively affected miles of coral reef as well as thousands of types of fish. If we don’t reduce our carbon footprint or conserve our local environment, our homes and local wildlife can’t avoid the seriously harmful effects of global warming.

Exercise 2: 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 1 to 5.

Tourism will always have an impact on the places that people visit. Sometimes the impact is positive, but most of the time it is negative. For example, a large number of visitors in one destination can cause bad effects on the environment. The question is, how can we minimize the problems while still allowing people to travel and visit places?

The main goal of eco-tourism is to limit the bad impact of tourism on the environment and local people. The task is to encourage tourists to think about what they do when they visit an area. There are many key points. Tourists should not litter, should stay on the paths, should not interfere with wildlife and should respect local customs and traditions. Some people consider eco- tourism to be a double-edged sword that has both advantages and disadvantages. They argue that tourism requires infrastructure such as roads and airports. The more tourists visit a destination, the more of infrastructure is necessary so that the tourists can stay and benefit the local community financially. However, it’s difficult to avoid damaging the environment and develop local tourism at the same time. Eco-tourism can only develop in the right way if governments can deal with the negative effects and make sure that modern improvements benefit the local people and environment, not just the tourists.

In 2002, the United Nations General Assembly celebrated the International Year of Eco-tourism (IYE) to evaluate global eco-tourism experiences. More and more people have chosen eco- holidays over the past 20 years. Eco-tourism truly plays a key role in the tourism industry in many countries like Kenya, Costa Rica, Ecuador and Nepal.

‚ Conservation is the sensible use and protection of natural resources including plants, animals, mineral deposits, soils, clean water, clean air, and fossil fuels such as coal, petroleum, and natural gas to ensure an adequate supply for future generations.

Natural resources are grouped into two categories, renewable and nonrenewable. A renewable resource is one that may be replaced over time by natural processes, such as fish populations or natural vegetation, or is inexhaustible, such as solar energy. The goal of renewable resource conservation is to ensure that such resources are not consumed faster than they are replaced.

Nonrenewable resources are those in limited supply that cannot be replaced or can be replaced only over extremely long periods of time. Nonrenewable resources include fossil fuels and mineral deposits, such as iron ore and gold ore. Conservation activities for nonrenewable resources focus on maintaining an adequate supply of these resources well into the future.

1. What is the purpose of conservation mentioned in the passage?

A. To make use of natural resources

B. To ensure an adequate supply of natural resources for future generations.

C. To replace renewable resource

D. To maintain an adequate supply of water for future.

Exercise 3: Read the following passage, and decide the statements are true (T) or false (F).

Once there were lots of pandas in the mountain of Western China. Today they are becoming extinct. The reason is that they cannot find enough food. Pandas eat bamboo leaves. They do not like another food. The bamboo grows very slowly. It can take 10 years for a bamboo cane to grow from a seed to a big plant. Some types of bamboo have seeds every 60 years. Pandas must wait many years for their food to grow. While the bamboo is growing, pandas do not have enough leaves to eat.

Farmers are using more and more of the land on the mountain side to grow food for man. The farmers cut down the bamboo. Bamboo leaves become less plentiful. Pandas cannot find enough food to eat. They starve and die.

China and World Wildlife Fund (WWF) are trying to save the panda. In 1979 they began to set up special parks where pandas live. One such park is the Wolong Reserve in Sichuan. The Wolong Reserve has the highest number of pandas in the world. Scientists come here to study the panda’s eating and mating habits. By learning more about the panda’s habits, scientists can save it from extinction.

1. There are many pandas in China nowadays F

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 32 to 36.

Man and most animals need a constant supply of water to live. Farmers need water for their crops. Hydroelectric dams hold back needed water and provide power for homes and industries.

Trees and grass, and other plant life play an important part in the natural circulation of water, thus help conserve it. Without plants, most water would run off as soon as it falls, taking away valuable soil. Rapid runoff would cause frequent floods, and leave little water during dry seasons.

Nature has many ways of conserving and controlling water. But man often upsets the water balance in his desire to grow more crops. He drains ponds, swamps and wet land. He ploughs under the natural soil, cuts timber, and dredges and straightens streams. These changes reduce natural storage of water and speed runoff.

Water can be held on the land by planting vegetation. Forests and grass should be planted where there are natural growths. Dams built across rivers help hold back the water. Reservoirs behind the dams store water during wet seasons for use in dry seasons. Dams help prevent floods by controlling the flow of water.

Note: to dredge = to make a river deeper

32. What is the topic of the passage?

A. Water circulation B. Water conservation C. Controlling water D. Use of water

33. What is the consequence of having no plants on land?
