Tourism will always have an impact on the places visited. Sometimes the impact is good, but often it is negative. For example, if lots of people visit one place, then this can damage the environment. The question is - how can we minimize the problems without preventing people from travelling and visiting places? 

The main aim of ecotourism is to reduce the negative impact that tourism has on the environment and local people. The idea is to encourage tourists to think about what they do when they visit a place. 

It's great to talk about protecting the environment, but how do you actually do this? There are a number of key points. Tourists shouldn't drop litter, they should stay on the paths, they shouldn't interfere with wildlife and they should respect local customs and traditions. 

Some people see ecotourism as a contradiction. They say that any tourism needs infrastructure - roads, airports and hotels.The more tourists that visit a place, the more of these are needed and, by building more of these, you can't avoid damaging the environment. 

But, of course, things aren't so black and white. Living in a place of natural beauty doesn't mean that you shouldn't benefit from things like better roads. As long as the improvements benefit the local people and not just the tourists, and the local communities are consulted on plans and changes, then is there really a problem? 

In 2002 the United Nations celebrated the "International Year of Ecotourism". Over the past twenty years, more and more people have started taking eco-holidays. In countries such as Ecuador, Nepal, Costa Rica and Kenya, ecotourism represents a significant proportion of the tourist industry.

Exobiology is the study of life that originates from outside of Earth. As yet, of course, no such life forms have been found. Exobiologists, however, have done important work in the theoretical study of where life is most likely to evolve, and what those extrateưestrial life forms might be like. What sorts of planets are most likely to develop life? Most scientists agree that a habitable planet must be terrestrial, or rock-based, with liquid surface water and biogeochemical cycles that somewhat resemble Earth’s. Water is an important solvent involved in many biological processes. Biogeochemical cycles are the continuous movement and transformation of materials in the environment. These cycles include the circulation of elements and nutrients upon which life and the Earth’s climate depend. Since (as far as we know) all life is carbon-based, a stable carbon cycle is especially important. The habitable zone is the region around a star in which planets can develop life. Assuming the need for liquid surface water, it follows that most stars around the size of our sun will be able to sustain habitable zones for billions of years. Stars that are larger than the sun are much hotter and bum out more quickly; life there may not have enough time to evolve. Stars that are smaller than the sun have different problem. First of all, planets in their habitable zones will be so close to the star that they will be “tidally locked” – that is one side of the planet will always face the star in perpetual daylight with the other side in the perpetual night. Another possible obstacle to life on smaller stars is that they tend to vary in their luminosity, or brightness, due to flares and “star spots”. The variation can be large enough to have harmful effects on the ecosystem. Of course, not all stars of the right size will give rise to life; they also must have terrestrial planets with the right kind of orbits. Most solar systems have more than one planet, which influence each other’s orbits with their own gravity. Therefore, in order to have a stable system with no planets flying out into space, the orbits must be a good distance from one another. Interestingly, the amount of space needed is roughly the width of a star’s habitable zone. This means that for life to evolve, the largest possible number of life-supporting planets in any star’s habitable zone is two. Finally, not all planets meeting the above conditions will necessarily develop life. One major threat is large, frequent asteroid and comet impacts, which will wipe out life each time it tries to evolve. The case of Earth teaches that having large gas giants, such as Saturn and Jupiter,.in the outer part of the solar system can help keep a planet safe for life. Due to their strong gravitation, they tend to catch or deflect large objects before they can reach Earth.

Say Sayonara to Sushi?
There are few meals as nutritious as a plate of fresh fish. Whether eaten steamed or raw, fish provides our bodies with healthy fats and it tastes great, too. Yet for years, the fishing industry has practised overfishing, depleting the world’s oceans. It has been estimated that 85 percent of stocks worldwide have been diminished to a dangerous level. Statistics show that the average person consumes more than four times as much fish as someone from the 1950s. As the world’s population grows and more people are able to afford pricier foods, the problem will likely get worse. In truth, knowledge of the shortage of fish is not something new. Since the late 1980s, despite increased technology and a greater demand for fish, the total global catch has not increased. Eager to make a buck, some fishermen have resorted to illegal tactics to catch more fish and increase their income. They will violate regulations by fishing in waters that are supposed to be off-limits. To make matters worse, they often use mile-long drift nets which trap and kill large numbers of unwanted marine life for no reason at all. These practices only serve to destroy fishes’ habitats and speed up the rate of population decline. As a result of dwindling fish supplies, many nations are turning to farmed fish. About half of the fish sold today is derived from this practice. Supporters point out its efficiency and that it is more feasible to support populations in this manner than with land animals. However, there are still many hurdles to overcome. Many of the current farm fisheries are poorly run by their owners. Poor practices can lead to marine pollution, as waters can be filled with fish manure and extra feed that is not consumed. Some farmed fish have limited space, which causes disease. This in turn can lead to health issues for the people who consume the fish. Still, some regard fish farming as the way of the future. They suggest that with a few modifications, it would be possible to meet the growing demand for fish. Others have suggested more drastic measures, such as placing a ten-year ban on capturing some species, to deal with the shortage. These people argue that a decade would provide sufficient time for the fish population to replenish itself hack to healthy levels. Hopefully, nations can come together and agree upon an effective course of action before it is too late.

Read the following passage and choose the best answer (A, B, C, D):
The principal difference between urban growth in Europe and in the North American colonies was the slow evolution of cities in the former and their rapid growth in the latter. In Europe they grew over a period of centuries from town economies to their present urban structure. In North America, they started as wilderness communities and developed to mature urbanism in little more than a century. In the early colonial days in North America, small cities sprang up along the Atlantic Coastline, mostly in what are now New England and the Middle Atlantic states in the United States and in the lower Saint Lawrence valley in Canada. This was natural because these areas were nearest England and France, particularly England, from which most capital goods were imported. Merchandising establishments were, accordingly, advantageously located in port cities from which goods could be readily distributed to interior settlements. Here, too, were the favored locations for processing raw materials prior to export. Boston, Philadelphia, New York, Montreal, and other cities flurished, and as the colonies grew, these cities increased in importance. This was less true in the colonial South, where life centered around large farms, known as plantations, rather than around towns, as was the case in the areas further north along the Atlantic coastline. The local isolation and the economic self-sufticiency of the plantations were antagonistic to the development of the towns. The plantations maintained their independence because they were located on navigable streams and each had a wharf accessible to the small shipping of that day. In fact, one of the strongest factors in the selection of plantation land was the desire to have it front on a water highway. When the United States became an independent nation in 1776, it did not have a single city as large as 50,000 inhabitants, but by 1820 it had a city of more than 100,000 people, and by 1880 it had recorded a city of over one million. It was not until after 1823, after the mechanization of the spinning and weaving industries, that cities started drawing young people away from farms. Such migration was particularly rapid following the Civil War (1861 -1865)

Although he created the game of basketball at the YMCA in Springfield, Massachusetts, Dr. James A. Naismith was a Canadian. Working as a physical education instructor at the International YMCA, now Springfield College, Dr. Naismith noticed a lack of interest in exercise among students during the wintertime. The New England winters were fierce, and the students balked at participating in outdoor activities. Naismith determined that a fast-moving game that could be played indoors would fill a void after the baseball and football seasons had ended. First he attempted to adapt outdoor games such as soccer and rugby to indoor play, but he soon found them unsuitable for confined areas. Finally, he determined that he would have to invent a game. In December of 1891, Dr. Naismith hung two old peach baskets as either end of the gymnasium at the school, and, using a soccer ball and nine players on each side, organized the first basketball game. The early rules allowed three points for each basket and made running with the ball a violation. Every time a goal was made, someone had to climb a ladder to retrieve the ball. Nevertheless, the game became popular. In less than a year, basketball was being played in both the United States and Canada. Five years later, a championship tournament was staged in New York City, which was won by the Brooklyn Central YMCA. The teams had already been reduced to seven players, and five became standard in the 1897 season. When basketball was introduced as a demonstration sport in the 1904 Olympic Games in St. Louis, it quickly spread throughout the world. In 1906, a metal hoop was used for the first time to replace the basket, but the name basketball has remained.
2. When was the first demonstration game of basketball held during the Olympics?

Read the passage below carefully, and then choose the best answer:
It’s in Your Genes
Every human being has about 25,000 genes. Your genes are part of your DNA. They give your body instructions on how to develop. For example, if your genes tell your body to build long, thin fingers, then you will have long, thin fingers. Your genes come from your parents, and they decide everything about you. They decide your hair colour, your eye colour, your height, and so on. Genes are still a bit of a mystery to scientists, but they are learning new things about them all the time. One issue that people often debate is this: Do our genes influence our personalities? These days, most people agree that the answer to this question is yes. Recent studies have shown that genes especially influence our self-control and our sense of purpose. Your sense of purpose is your desire to have goals in your life. If a person really wants to accomplish something and do well in life, he or she has a sense of purpose. A person who does not care about goals has no sense of purpose. Although scientists agree that our genes influence our personalities, there is another question. How much do they influence us? Can we control ourselves, or do our genes control us? People everywhere are still debating this issue. So far, we don’t really have an answer. Genes also affect your health. If a gene has a problem, it is called a mutated gene. Some mutated genes can cause diseases. That is why if a person has a certain health problem, his or her child is more likely to have that same problem. The child also has the mutated gene. As scientists and doctors learn more about genes, they are also developing a new kind of medicine: gene therapy. Therapy is help for a mental or a physical problem. Gene therapy means fixing or replacing mutated genes. Scientists are still experimenting on gene therapy. It is possible that in the future, gene therapy will help doctors prevent and cure diseases that are caused by mutated genes.
