In 1971, Sue Coppard worked as a secretary in London. While she enjoyed city life, Sue also missed the countryside where she spent most of her time as a child. So she offered to help out on a farm, or more specifically, an organic farming programme organized by a nearby college. She got a few people to volunteer as well, and they spent the weekend doing “housework,” which involved clearing bushes and cleaning drains. Afterwards, the farm managers said they could come back anytime to help out. Sue put a small ad in a magazine, offering people the chance to volunteer at the organic farm. The volunteer programme grew quickly, and soon other organic farmers joined in, asking for people to help out. With so many people and farms involved, someone needed to organize the different groups. A few of the original volunteers started WWOOF (World Wide Opportunities on Organic Farms) to help volunteers and farmers find one another. Today, at least 50 different countries have WWOOF organizations, and many other countries have individual farms that participate in the movement. While WWOOF is still a weekend activity for some, it now welcomes travellers and people who visit to live and work on farms for longer periods of time. WWOOF volunteers can stay on a farm for weeks or even months at a time in exchange for hands-on farming and gardening experience. The work can be exhausting, but volunteers think it’s worth it. By working on farms, the volunteers interact with farmers and develop a love for the outdoors and organic farming. Many travellers now use WWOOFing as a way to visit new countries and experience new cultures. As travellers will discover, every WWOOF opportunity is a bit different. In Serbia, you can find Misa and Olja, a couple whose farm is known for its hard cheeses and for its bread made from homegrown grains. Finca Amiruca, a farm in Ecuador, teaches volunteers how to grow peanuts, plantains, and yucca. When volunteering in Japan, you may get to learn about growing rice. WWOOF is only one of the many unique volunteer opportunities available. Volunteering is something that anyone can do, and a wide variety of organizations accept or even welcome volunteers. So the next time you get the itch to be active on the weekend or on vacation, why not look for a good cause to spend your energy on?

Getting Curious about Curiosity’s Mission to Mars
The topic of space exploration reached a high point during the 1960s, as Soviets and Americans competed for dominance. Yet after the Soviets put the first man in space and Americans landed the first men on the moon, many people lost interest as nothing else could compare to these groundbreaking accomplishments. Recently, a robotic rover on a mission to Mars has generated massive interest the public. Curiosity is a robotic car-sized rover that is part of NASA’s long-term plan to learn more about the terrain and conditions on the Red Planet. One of its main goals was to determine whether or not it was possible for life to develop on Mars. Using mechanical arms, Curiosity can gather soil and rock samples from the ground and analyze them to determine their chemical composition. Since transporting around Mars was vital to the success of the mission, a lot of effort was put into Curiosity’s transportation abilities. Mars’ terrain is not smooth, so designers enabled Curiosity to roll over bumpy areas. Once Curiosity left the Earth, there would be no opportunities to repair it, so engineers also had to be spot on about Curiosity’s power solution. Therefore, they devised a system that can generate power internally from a radioisotope generator. Finally, to capture stunning pictures of Mars, Curiosity was equipped with several state-of-the-art cameras. The cameras also help the rover avoid hazards, navigate, and detect information about the atmosphere. After a 350-million-mile journey, Curiosity landed on Mars in 2012, an impressive 1.5 miles away from its initial target. Upon arrival, NASA’s website crashed due to an overload of visitors. People just couldn’t seem to get enough information on the mission. But the real thrills came in the weeks and months that followed, as people got their first real glimpse about what life was really like on Mars. The mission was originally supposed to last for two years, but scientists are now optimistic that it could continue for up to 15 years, depending on Curiosity’s condition. No matter what happens at this point, it is safe to say that Curiosity’s mission to Mars has been a smashing success.

The ubiquitous bar code, developed more than twenty years ago, is not a stagnant product. On the contrary, the technology has been improved so that it can be used more efficiently. Much less expensive than a computer chip, the bar code can hold more information than it had in the past by adding a second dimension to the structure. The bar code consists of a series of parallel vertical bars or lines of two different widths, although sometimes four widths are used, printed in black on a white background. Barcodes are used for entering data into a computer system. The bars represent the binary digits 0 and 1, just like basic computer language, and sequences of these digits can indicate the numbers from 0 to 9, which can then be read by an optical laser scanner and processed by a digital computer. Arabic numbers appear below the code. The traditional bar code has been used to monitor skiers at ski lifts and to determine price and perform inventory control on groceries, drugs, medical supplies, manufactured parts, and library books to name a few. The bar code used on grocery products, introduced in the 1970s, is called a universal product code (or UPC) and assigns each type of food or grocery product a unique code. The five digits on the left are assigned to a particular manufacturer or maker and the five digits on the right are used by that manufacturer to identify a specific type or mark of product. Traditional single dimension bar codes are not readily customizable because there is little extra space. The two-dimensional bar code, with an information density of 1,100 bytes, allows a considerably greater amount of information to be coded than does the traditional bar code, including customized information. [A] It also has built-in redundancy, meaning that the identical information is duplicated on the same code. [B] Therefore, if the code is damaged, it can still be read. [C] The technology even allows pictures or texts to be contained within the code, as well as bar code encryption. [D] The new technology dramatically reduces the errors of the single dimensional bar code and reduces the enormous costs that some companies have reported in the past.

Read the following passage and choose the best answer (A, B, C, D):
Although noise, commonly defined as unwanted sound, is a widely recognized form of pollution, it is very difficult to measure because the discomfort experienced by different individuals is highly subjective and, therefore, variable. Exposure to lower levels of noise may be slightly irritating, whereas exposure to higher levels may actually cause hearing loss. Particularly in congested urban areas, the noise produced as a by-product of our advancing technology causes physical and psychological harm, and detracts from the quality of life for those who are exposed to it.Unlike the eyes, which can be covered by the eyelids against strong light, the ear has no lid, and is, therefore, always open and vulnerable; noise penetrates without protection.Noise causes effects that the hearer cannot control and to which the body never becomes accustomed. Loud noises instinctively signal danger to any organism with a hearing mechanism, including human beings. In response, heartbeat and respiration accelerate, blood vessels constrict, the skin pales, and muscles tense. In fact, there is a general increase in functioning brought about by the flow of adrenaline released in response to fear, and some of these responses persist even longer than the noise, occasionally as long as thirty minutes after the sound has ceased.Because noise is unavoidable in a complex, industrial society, we are constantly responding in the same way that we would respond to danger. Recently, researchers have concluded that noise and our response may be much more than an annoyance. It may be a serious threat to physical and psychological health and well-being, causing damage not only to the ear and brain but also to the heart and stomach. We have long known that hearing loss is America’s number one nonfatal health problem, but now we are learning that some of us with heart disease and ulcers may be victims of noise as well. Fetuses exposed to noise tend to be overactive, they cry easily, and they are more sensitive to gastrointestinal problems after birth. In addition, the psychic effect of noise is very important. Nervousness, irritability, tension, and anxiety increase affecting the quality of rest during sleep, and the efficiency of activities during waking hours, as well as the way that we interact with each other.

Read the following passage and choose the best answer (A, B, C, D):
Although only a small percentage of the electromagnetic radiation that is emitted by the Sun is ultraviolet (UV) radiation, the amount that is emitted would be enough to cause severe damage to most forms of life on Earth were it all to reach the surface of the Earth. Fortunately, all of the Sun’s ultraviolet radiation does not reach the Earth because of a layer of oxygen, called the ozone layer encircling the Earth in the stratosphere at an altitude of about 15 miles above the Earth. The ozone layer absorbs much of the Sun’s ultraviolet radiation and prevents it from reaching the Earth. Ozone is a form of oxygen in which each molecule consists of three atoms (O3) instead of the two atoms (O2) usually found in an oxygen molecule. Ozone forms in the stratosphere in a process that is initiated by ultraviolet radiation from the Sun. UV radiation from the Sun splits oxygen molecules with two atoms into free oxygen atoms, and each of these unattached oxygen atoms then joins up with an oxygen molecule to form ozone. UV radiation is also capable of splitting up ozone molecules; thus, ozone is constantly forming, splitting, and reforming in the stratosphere. When UV radiation is absorbed during the process of ozone formation and reformation, it is unable to reach Earth and cause damage there. Recently, however, the ozone layer over parts of the Earth has been diminishing. Chief among the culprits in the case of the disappearing ozone, those that are really responsible, are the chlorofluorocarbons (CFCs). CFCs meander up from Earth into the stratosphere, where they break down and release chlorine. The released chlorine reacts with ozone in the stratosphere to form chlorine monoxide (ClO) and oxygen (O2). The chlorine then becomes free to go through the cycle over and over again. One chlorine atom can, in fact, destroy hundreds of thousands of ozone molecules in this repetitious cycle, and the effects of this destructive process are now becoming evident.

Inside a 4D Film
A lot of people think that 3D films are pretty cool. When you watch a 3D film, it sometimes feels like you can reach out and touch the things that you see. In the future, however, 3D might be replaced by something even more advanced: 4D. What you see in a 4D film is the same as what you see in a 3D film. The screen is the same, and the glasses are the same. 4D films are different because they don’t use 3D technology. People in the audience also feel physical things during the films. Let’s look at a few examples. Let’s say that you are watching a film about earthquakes. If you are watching a 4D film, maybe your seat will suddenly start to shake. It will feel like you are in the middle of an earthquake, but you are not. The 4D effects make your seat shake. Or perhaps during the film, one of the characters gives flowers to another character. The people in the cinema might suddenly smell flowers. The point of 4D films is to make people feel like they are in the film. When we watch films these days, we only use two senses: our sense of sight and our sense of hearing. If we use our other senses, the film might feel more real to us. 4D films already exist. The film Avatar was released everywhere in 3D, but in Korea and Hong Kong, it was also released in 4D. People who watched Avatar in 4D feel wind and rain. They also smelled smoke from the weapons in the film, and sometimes their seats moved. Will 4D replace 3D films? It is possible, but we can’t be sure yet. One problem with 4D films is that it is very expensive to show them in theaters. Before a theater shows a 4D film, it has to buy a lot of special equipment. However, 4 films are catching on. Other films shown in 4D include Shrek 4-D, and Iron Man 3.

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 following questions from 35 to 42. 
What is commonly called pepper in reality comes from two very different families of plants. Black and white pepper both come from the fruit of the Piper nigrum, a vine with fruits called peppercorns. The peppercorns turn from green to red as they ripen and finally blacken as they dry out. The dried-out peppercorns are ground to obtain black pepper. White pepper, which has a more subtle flavour than black pepper, comes from the same peppercorns as black pepper. To obtain white pepper, the outer hull of the peppercorn, the pericarp, is removed before the peppercorn is ground. Red and green pepper, on the other hand, come from a completely different family from black and white pepper. Red and green peppers are from the genus Capsicum. Plants of this type generally have tiny white flowers and fruit which can be any of a number of colours, shapes and sizes. These peppers range in flavour from very mild and sweet to the most incredibly burning taste imaginable. Bell peppers are the most mild, while habanros are the most burning. 
Christopher Columbus is responsible for the present-day confusion over what pepper is. The Piper nigrum variety of pepper was highly valued for centuries, and high demand for pepper by Europeans was a major cause of the fifteen-century push to locate ocean routes to the spice-growing regions of Asia. When Columbus arrived in the New World in 1492, he was particularly interested in finding black pepper because of the high price it would command in Europe. Columbus came across plants from the Capsicum family in use among people of the New World, and he incorrectly identified them as relatives of black pepper. Columbus introduced the spicy Capsicum chili peppers to Europeans on his return from the 1492 voyage, and traders later spread them to Asia and Africa. These Capsicum peppers have continued to be called peppers in spite of the fact that they are not related to the black and white pepper of the Piper nigrum family. 

It can be inferred from the passage that chili peppers originally came from ______.
