The Great Energy Debate
Modern civilization is heavily dependent on energy. Without reliable power sources, we couldn’t operate machines, use transportation, communicate via Internet, or do many other things. Although everyone recognizes the importance of energy, deciding what kind of energy the world should use in the future is not a simple task. The two leading candidates for this role are green energy and nuclear energy. Currently, most of the energy we use is derived from fossil fuels. Although this energy source has got us this far, there are several problems with it. For starters, it is a finite resource which is quickly running out. Some analysts have even estimated that the Earth could run out of coal and oil within the next 50 years. Burning fossil fuels also creates large amount of pollution, which is harmful to the environment. Although fossil fuels still provide the majority of our power, governments are seeking better energy sources to use going forward. Green energy is one option that is becoming increasingly attractive. It includes technologies such as solar, wind, and hydro power. These are seen as clean sources of energy because they cause very little pollution. In addition, they are completely renewable, so there is no danger that it will run out. The major disadvantage with green energy sources is that they are not cheap. The other alternative is nuclear power. Like green energy, it is also a renewable source of power that will not run out, and it also doesn’t produce air pollution. In addition, nuclear power is more reliable than green energy, as it doesn’t depend on sunshine, rain, or wind to operate. The major issues with nuclear power are safety concerns and nuclear waste. Nuclear power plants create a considerable amount of nuclear waste which is extremely hazardous to people’s health. If they happen to have a meltdown, this could destroy the surrounding area for years to come. The recent nuclear disaster in Fukushima, Japan brought this reality into the spotlight once again. In response, Germany announced it would close down eight of its nuclear plants immediately, and close the rest by 2022. Meanwhile, other nations refuse to give up on nuclear power, stating that these disasters are rare. The debate of whether to use green or nuclear power will likely continue for some time. In the end, it is quite possible that both energy sources will be used to fuel our planet.

Make Home a Little Nicer
Some people think that if they don’t have a yard, they can’t keep a garden. Fortunately, that’s not true. For people who live in apartment buildings, there is another option: rooftop gardens. A rooftop garden is just a garden that you keep on your roof. Rooftop gardens are very popular in cities. Most building roofs go to waste – people don’t use that space for anything. Putting a garden on your roof is a nice way to turn an empty space into something that is pretty and relaxing. Rooftop gardens are not a new idea. About 2,600 years ago, people in Ancient Mesopotamia planted rooftop gardens. There were similar gardens in Ancient Rome and Ancient Egypt. These gardens had a very important purpose. Many ancient cities had walls. The enemy army usually tried to destroy the city’s food, so the people in the city kept their gardens on top of their walls. That way, they could continue to grow food. Today’s rooftop gardens don’t keep us alive, but they still have nice benefits. Plants absorb heat, so if there are a lot of them on a rooftop, they make the whole building cooler. As a result, people in the building use the air conditioning less which means they use less electricity. One study said that if every roof in Tokyo had a garden, the city would save more than one million dollars a day on electricity. Rooftop gardening is harder than regular gardening. Here are some tips. First of all, be safe. Build a fence around your garden. You don’t want the wind to blow plants off your roof! Also, remember that rooftop gardens get more sun. If you have a plant that shouldn’t get too much sun, remember to put it in the shade sometimes. There are many other things that you need to know before you start a rooftop garden. Do some research and then give it a try. You’ll make your little part of the city much nicer.

1. Why did people in ancient cities have rooftop gardens?

The Internet: Changing Everything
Let’s do a little experiment: Take five minutes, and find some information about Angola. How did you get your information? How much information were you able to get? Chances are, you probably just went online and typed the word “Angola”. You were probably able to find out all sorts of things. This experiment shows us how useful the Internet is. Over the last 20 years, the Internet has changed the way that we live, work, and study. The biggest change has been the way that we access information. Twenty years ago, you would have needed an encyclopedia to learn about Angola. If you had wanted information, you would have had to get out of your chair, open your encyclopedia, and look up the word “Angola”. Today all you need is about five seconds and you’ll have the exact same information. This technology makes work a lot faster and more efficient. It has also made information storage a lot easier and neater. Twenty years ago, offices had papers and files all over the place. If you wanted to find a file, you had to open a desk drawer and find the right piece of paper. Today, many of us keep our files in cloud storage. Cloud storage is a technology that lets people store files on the Internet. All you have to do is to sign into the site, and you can find all of your files in seconds. Another big change is communication. These days more and more people are working from home. People have “home offices”. They just do their work at their house and e-mail it to their company. It makes life a lot easier. Some people don’t like these changes. They say that life is too convenient these days, and it is making people lazy. However, most people think that even if this technology makes us a little easier, it still has more benefits than disadvantages. In the end, it doesn’t matter what we think. The Internet has changed all of our lives forever.

Read the following passage and choose the best answer (A, B, C, D):
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.

Clean and Popular
Wind power is a very clean source of energy. This is how wind power works. Wind makes windmills spin. When the windmills spin, they make electricity. Then we can use the electricity. Many people think that wind power is new, but that is not true. For thousands of years, people have used wind to sail boats and move water. We still do those things today, but these days we mostly use wind power to make electricity. Wind power is a very popular source of energy. Most people think that should use it more and more. First of all, it is clean. Windmills don’t pollute the environment at all. Second, we can use wind power forever. After all, we will always have wind. In addition, wind power is cheap, and it is getting even cheaper. A lot of people don’t understand wind power very well. They believe that there are problems with wind power, but many of those problems are not real. For example, some people say that windmills are dangerous for birds. That used to be true, but it isn’t true anymore. Old windmills killed birds because they spun very fast. New windmills spin slowly, and they aren’t dangerous for birds. However, there are real problems with windmills. One problem is that many people think windmills are very ugly. This is a problem for some people, because windmills are often in very pretty areas. Besides, wind doesn’t blow all the time, so we can’t use wind power all year round. Finally, windmills are noisy. Wind power is becoming more and more common. Right now, more than 80 countries use wind power. About 2.5 percent of the world’s power comes from the wind. For some countries, that number is a lot higher. Wind power gives Denmark more than 25 percent of its electricity.
