The Wonders of Wetlands
If you’re searching for scenic places or areas, visiting wetlands probably won’t be high on your list. Wetlands are areas of land that are often saturated with water and they are quite an eyesore. Although they might not look very pretty, they play an important part in keeping the environment clean and suitable for plant and animal life. With the exception of Antarctica, wetlands occur naturally on every continent. There are many different types of wetlands on the Earth, including bogs, swamps, and marshes. Along with rainforests, they are among the most diverse places on the Earth. In addition to naturally-occurring wetlands, humans are creating artificial ones for a number of purposes related to water management. One of the main benefits of wetlands is that they can prevent floods. They do so by storing water temporarily and then slowly releasing it over time. Wetlands operate similarly to a sponge. When it rains heavily and water levels rise, they absorb the excess water. This prevents runoff from entering streams and keeping them from overflowing. Then, when water levels become low in the future, they will release it. In many cases, wetlands offer a much more affordable solutions than dams. However, it’s important to note that wetlands, like dams, don’t eliminate all dangers from flooding. In cases of extremely heavy rainfall, wetlands can fill up and any additional water will start to run off. Wetlands can also play a part in water purification. Agricultural practices, urban runoff, and sewage waste are a major cause of water pollution. Wetlands contain plants and organisms that can reduce this pollution by filtering out unwanted substances such as chemicals, and decomposing matter, as well as sediment. Wetlands have additional benefits for the environment as well. They can help to feed nearby fish populations by releasing vegetative matter to rivers. Also, many amphibians use wetlands as breeding grounds because it provides places for foraging and the shallow water they require for reproduction. Some birds also use wetlands for migration, as they can settle in trees and then raid the wetland’s waters for fish when they’re hungry. Although wetlands may not look pretty, it’s clear that they are capable of doing the dirty work required to keep our planet clean and ensure that the circle of life remains unbroken.

      Centuries ago, man discovered that removing moisture from food helped to preserve it, and that the easiest way to do this was to expose the food to sun and wind. In this way the North American Indians produced pemmican (dried meat ground into powder and made into cakes), the Scandinavians made stockfish and the Arabs dried dates and apricots.

      All foods contain water - cabbage and other leaf vegetables contain as much as 93% water, potatoes and other root vegetables 80%, lean meat 75% and fish anything from 80% to 60% depending on how fatty it is. If this water is removed, the activity of the bacteria which cause food to go bad is checked.

      Fruit is sun-dried in Asia Minor, Greece, Spain and other Mediterranean countries, and also in California, South Africa and Australia. The methods used vary, but in general the fruit is spread out on trays in drying yards in the hot sun. In order to prevent darkening, pears, peaches and apricots are exposed to the fumes of burning sulphur before drying. Plums for making prunes, and certain varieties of grapes for making raisins and currants, are dipped in an alkaline solution in order to crack the skins of the fruit slightly and remove their wax coating, so increasing the rate of drying.

      Nowadays most foods are dried mechanically; the conventional method of such dehydration is to put food in chambers through which hot air is blown at temperatures of about 110oC at entry to about 45oC at exit. This is the usual method for drying such things as vegetables, minced meat, and fish.

      Liquids such as milk, coffee, tea, soups and eggs may be dried by pouring them over a heated horizontal steel cylinder or by spraying them into a chamber through which a current of hot air passes. In the first case, the dried material is scraped off the roller as a thin film which is then broken up into small, though still relatively coarse flakes. In the second process it falls to the bottom of the chamber as a fine powder. Where recognizable pieces of meat and vegetables are required, as in soup, the ingredients are dried separately and then mixed.

      Dried foods take up less room and weigh less than the same food packed in cans or frozen, and they do not need to be stored in special conditions. For these reasons they are invaluable to climbers, explorers and soldiers in battle, who have little storage space. They are also popular with housewives because it takes so little time to cook them.

The final product of the process of drying liquids that uses the first method will be ______.

Is It Safe?
Fracking is a way of getting energy from the ground. First, a special liquid is put into the ground. This liquid cracks rocks under the ground. After the rocks are cracked, oil moves through the cracks. Then it is much easier to take the oil from the ground. Fracking was started in 1947. These days, we are doing more and more fracking. That is why everyone is suddenly talking about it. A lot of people say that fracking is a good way to get energy. There is some gas that is very difficult to take from the ground. If we didn’t use fracking, we would not be able to get this oil. They say that because the world need more energy, we have to use fracking. Also, it is said that fracking creates a lot of jobs. However, many people are against fracking. They say that fracking’s “special liquid” pollutes the ground, the water, and the air. People who live near fracking areas could have health problems. Moreover, fracking is very loud. In some countries, fracking is now illegal. The first country to make fracking illegal was France. They did that in 2011. In other countries like England, fracking is legal, but there are many rules that control it. Other countries are waiting to learn more about fracking before they decide whether or not to allow it. However, fracking is very big in the United States. The US is number one fracking country in the world. People who support fracking say that it can be very safe. They say that first, we need strong laws to make sure that fracking is always done safely. Second, they say that fracking needs safe methods and good technology. It is said by many that after we develop these things, fracking will be great for the whole world. However, other people want fracking to be illegal everywhere. They say that it will never be safe. We still don’t know enough about fracking. After we learn more about it, we can decide whether it is really a safe way to get energy or not.

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)

It is a characteristic of human nature that people like to get together and have fun, and people live during America's frontier days were no exception. However, because life was hard and the necessities of day-to-day living took up their time, it was common for recreation to be combined with activities necessary for survival. One example of such a form of recreation was logrolling. Many frontier areas were heavily wooded, and in order to settle an area it was necessary to move the trees. A settler could cut down the trees alone, but help was needed to move the cut trees. After a settler had cut a bunch of trees, he would then invite is neighbours over for a logrolling. A
logrolling is a community event where families got together for a combination of work and fun. The women would bring food and have a much needed and infrequent opportunity to relax and chat with friends, the children would play together exuberantly, and the men would hold lively competitions that involved rolling logs from place to place as quickly as possible. This was a day of fun for everyone involved, but as its foundation was the need to clear the land.

The main idea of the passage is that in America's frontier days     .

Are Human Beings Getting Smarter?
Do you think you are smarter than your parents or grandparents? According to James Flynn, a professor at a New Zealand university, you might be. Over the course of the last century, IQ test scores of people in some countries have got increasingly better - on average, three points better for every decade that has passed. This trend of improving scores is known as “the Flynn effect,” and scientists want to know what is behind it. IQ tests and other similar tests are designed to measure general intelligence rather than knowledge. Flynn knew that intelligence is partly inherited from our parents and partly the result of our environment and experiences, but the improvement in test scores was happening too quickly to be explained by heredity. So what happened in the 20th century that led to higher test scores? Scientists have proposed several explanations for the Flynn effect. Some suggest that the improved test scores simply reflect an increased exposure to tests in general. Because we take so many tests, we learn test-taking techniques that help us perform better. Others have pointed to better nutrition, which results in babies being born larger, healthier, and with more brain development than in the past. Another possible explanation is a change in educational styles - children are encouraged to discover things for themselves rather than just memorizing information. This could prepare people to do the kind of problem-solving that intelligence tests require. Flynn himself suggested that learning new technologies may have improved people’s problem-solving skills. This may be true for the first decade of his tests, when IQ scores in many countries increased. However, in recent years, IQ test scores in some countries have begun to decline. Data from Norway, the Netherlands, Australia, and Great Britain have shown that as these countries become more and more modern, IQ scores have begun to drop. While scientists aren’t sure what is causing this decline, they think technology is dramatically changing the way that we learn and get information. For example, people are now able to access all kinds of information easily using online resources like Google or Wikipedia. The danger is when they start to rely too much on these sources of information, and not do any thinking for themselves. Lifestyle changes that come with modem technology may also have a negative effect on intelligence, such as video games and television making people less social.  So while the world may have got smarter over the 20th century, improving technology and changing lifestyles may soon reverse that trend.

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:
Most people can remember a phone number for up to trirty seconds. When this short amount of time elapses, however, the numbers are eerased from the memory. How did the information get there in the first place? Information that makes its way to the short term memory (STM) does so via the sensory storage area. The brain has a filter which only allows atimuli that is of immediate interest to pass on to the STM, also known as the working memory.
There is much debate about the capacity an duration of the short term memory. The most accepted theory comes from George A.Miller, a cognitive psychologist who suggested that humans can remember approximately seven chunks of information. A chunk is defined as a meaningful unit of information, such as a word or nam rather than just a letter or number. Modern theorists suggest that one can increase the capacity of the short term memory by chunking or classifying similar information together. By organizing information, one can optimize the STM, and improve the chances of a memory being passed on to long term storage.
When making a conscious effort to memorize something, such as information for an exam, many people engage in “rote rehearsal”. By repeating something over and over again, one is able to keep a memory alive. Unfortunately, this type of memory maintenance only succeeds if there are no interruptions. As soon as a person stops rehearsing the information, it has the tendency to disappear. When a pen and paper are not handy, people often attempt to remember a phone number by repeating it aloud. If the doorbell rings or the dog barks to come in before a person has the opportunity to make a phone call, he will likely forget the number instantly. Therefore, rote rehearsal is not an efficient way to pass information from the short term to long term memory. A better way is to practice “elaborate rehearsal”. This involves assigning semantic meaning to a piece of information so that it can be filed along with other pre-existing long term memories.
Encoding information semantically also makes it more retrievable. Retrieving information can be done by rocognition or recall. Humans can easily recall memories that are stored in the long term memory and used often; however, if a memory seems to be forgotten, it may eventually be retrieved by prompting. The more cues a person is given (such as pictures), the more likely a memory can be retrieved. This is why multiple choise tests are often used for subjects that require a lot of memorization.

Space Tourism
If you are like most people, you probably dream of spending your next vacation sightseeing or relaxing in a tropical spot. But pretty soon, you may have the option of blasting into space and exploring the universe. It appears that space tourism may start to experience a boom that is sure to be out of this world. Since ancient times, humans have surely dreamed about visiting space. However, it was just a fantasy until 1961, when Soviet cosmonaut Yuri Gagarin became the first person to fly into space. Yet in the years following, only a few highly-trained Soviet and American astronauts managed to leave the Earth’s atmosphere. In the mid-1980s, the US began to relax some of its restrictions. In 1986, an engineer named Charles Walker became the first non-government employee to fly into space. A year later, an American teacher named Christa McAuliffe was chosen to be the first teacher in space. Unfortunately, the Space Shuttle she was on, The Challenger, crashed during takeoff, killing everyone on board. Space tourism got an unexpected boost from the collapse of the Soviet Union. With Russia’s space programme in dire need of money, it became open to offers for space tourism. In 1990, a Japanese reporter was allowed to fly with a Russian crew into space, but the trip would cost his employer $28 million. In the late 1990s, a private company, MirCorp, started organizing trips to space for wealthy individuals. Now, many other companies are trying to do the same. Still, most people who want to become space tourists face a major barrier: the price. Early space tourists have paid dozens of millions of dollars for a seven-to- ten-day stay outside the Earth. However, there are some indications that the price will come down in the near future. Some corporations are gearing up for this with big plans to make space a more hospitable place. The luxurious hotel chain Hilton has expressed interest in opening a space hotel in the next 15 to 20 years. Meanwhile, some experts believe that flights to and from the moon could become a common occurrence within a few decades. Hopefully someday soon we will all have the chance to get to know our solar system a little bit better.

Read the following passage and choose the best answer (A, B, C, D):
Cholera, a highly infectious disease, has resulted in millions of deaths time after time over centuries. It is caused by the bacterium Vibrio cholera, first isolated by Robert Koch in 1883. The organism enters the body through the digestive tract when contaminated food or water is ingested.The bacteria multiply in the digestive tract and establish infection. As they die, they release a potent toxin that leads to severe diarrhea and vomiting. This results in extreme dehydration, muscle cramps, kidney failure, collapse, and sometimes death. If the disease is treated promptly, death is less likely. In many countries, a common source of the organism is raw or poorly cooked seafood taken from contaminated waters. The disease is especially prevalent after a natural disaster or other destruction that results in a lack of fresh water. Sewer systems fail, and waste travels into rivers or streams; piped water is not available so people must take their drinking and cooking water from rivers or streams. Because people frequently develop communities along waterways, the disease can be spread easily from one community to the next community downstream, resulting in serious epidemics
