The Greatest Light Show on the Earth
If you are a fan of amazing visual displays, planetariums around the world offer some entertaining laser-light shows that are often accompanied by popular music. Yet if you want to see the world’s greatest light show, you won’t be able to catch it indoors. Instead, you will have to head to one of the Poles. In certain spots, you will be treated to colourful streaks of light dancing across the sky. This incredible display is the aurora borealis, and every year people from all corners of the globe flock to witness its wonders firsthand. The Aurora Borealis, or Northern Lights, got its official name in 1621. The name combines the name of the Roman goddess of the dawn, Aurora, and the Roman god of the north wind, Boreas. In ancient times, the aurora completely baffled people’s minds, as science was far more primitive than it is today. Nevertheless, they created many myths to explain them. The Vikings believed the lights were the reflection of dead maidens. The Scots thought they were supernatural beings battling in heaven. Meanwhile, Eskimos thought that the lights were dead souls, and when the colours changed, it was their attempt to contact living friends and relatives. It was not until 2008 that a team of scientists from ULCA finally concluded with certainty what the true cause of these dancing light is. The process begins when solar winds carry charged particles from the Sun through space and into the Earth’s atmosphere. When these charged particles enter the Earth’s atmosphere, they are magnetically attracted to the Earth’s poles. During their journey to these points, they come in contact with nitrogen and oxygen atoms in the sky. These collisions are what cause the aurora. The heights at which the collisions occur determine the colours of the individual lights. For example, when the solar winds collide with nitrogen at least than 96 kilometres above the Earth’s surface, the lights will be blue. If the same collision occurs above 96 kilometres, however, the light will be purple. Or, if the solar wind particles collide with oxygen, the colours produced will be either red or green. However, merely understanding how the aurora works does not do this phenomena justice. To truly appreciate the full splendor of the aurora, you will have to see this Natural Wonder of the World in person.

Getting Focused and Flexible with Yoga
In a small room, men and women are getting a great workout. However, there are no weights in this gym. The only piece of equipment is a small rubber mat. On it, they strike unusual poses which are held for minutes at a time. An instructor goes from student to student urging them to relax and breathe deeply, while inspecting their posture. In the end, through the art of yoga they hope to balance their body, mind, and spirit. Yoga originated in India over 2,000 over years ago. The first yogis weren’t looking to lose weight or get themselves in great shape. Instead, they practise yoga to help them achieve liberation. Yoga became an important part of Hindu culture, and it is mentioned in nearly all of the religion’s ancient scriptures. It wasn’t until the 19th century, however, that Westerners took notice of yoga. In the 1890s, Swami Vievekananda became the first yoga teacher to take on Western students when he toured the US and Europe. His lessons focused primarily on the spiritual aspects, and his speeches intrigued many intellectuals, but it would take some time before yoga would catch on with the masses. That didn’t happen until the 1980s when many Americans and Europeans embraced yoga during a worldwide exercise boom. Yet once it took hold, yoga has increased popularity year by year. It is estimated that over 20 million Americans now practice yoga regularly. A main reason why contemporary people are hooked on yoga is that it helps to relieve work-related stress. Students are taught to breathe slowly and deeply while concentrating on the present moment and letting go of the past. The challenging postures help to balance the negative effects people experience from sitting in chairs all day. The poses also help people to regain flexibility and improve circulation, which is particularly useful to the elderly. As yoga became commercialized in the West, many new branches were formed. Ashtanga yoga moves at a fairly quick pace, flowing from pose to pose, power yoga, on the other hand, offers workouts that are designed to increase strength. Another popular style, hot yoga, has students practise in hot environments to help them burn more calories. If you are thinking of studying yoga, try them all and let your heart decide which one is best for you.
3. The word “that” in paragraph 2 refers to __________

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.

The word “it” in paragraph 3 refers to     .

Don’t Handle with Care
People always go shopping for the latest and greatest gadgets. Speed, performance, and the latest functions are always key factors before making a purchase. Yet the most important factor of all, which often isn’t considered, is a product’s durability. After all, if a product breaks easily and can’t be repaired, the buyer will have wasted their investment. In other cases, weakly-designed product can cost someone their life. Thankfully, today’s inventors and engineers coming up with some incredible ways to ensure that many products can survive the most difficult situations. One area where durability is absolutely essential is in designing weaponry. In the industry, lapses in quality can lead to death. Designers of military vehicles have recently made great strides in creating some extra tough bulletproof vehicles. Researchers were inspired by the advances made with a similar technology, bulletproof vests. This equipment, which keeps police officers and soldiers protected from gunfire, has been continually upgraded as time has gone on. In order to get tougher, these vests have got lighter, so officers and soldiers can move more freely while working. Beautiful screens, a fast computer processor, and the latest software are probably the biggest concerns for most people shopping for new smartphones. Yet, since most mobiles will be subject to their fair share of bumps and bruises during their life cycle, durability should also be a major concern. A major breakthrough in recent years was the invention of Gorilla Glass. This technology not only prevents devices from breaking when dropped on hard surfaces, but it also makes them scratch-resistant as well. Gorilla Glass screens are given molten alkaline salt baths that produce a hard, compressed layer at the surface. Before a screen can crack, it will have to penetrate this rugged surface, which takes a large degree of force. Recently, another new technique called electrospinning was developed that could make future products even tougher to break. The process involves applying high voltage to a polymer to create a strand of nanofiber. Products designed with the material will be able to absorb more energy without breaking. Researchers are aiming to lighten up aircraft and potentially decrease the damage planes suffer in crashes. Hopefully, these advances are just the beginning. Although science has come a long way in helping manufacturers to create more durable products, the next century should surely bring some even more incredible improvements.

No More Polar Bears?
We all know that the Earth is getting warmer and warmer. This problem is called “global warming”. We also know that global warming is causing a lot of problems. Ocean levels are getting higher and higher. Because ocean levels are getting higher, storms are getting stronger and stronger. This list of problems goes on and on. Animals are suffering a lot because of global warming. Polar bears are suffering more than most animals. This is because polar bears live in the North Pole. In the North Pole, global warming is making ice melt. Polar bears hunt from large pieces of floating ice. They jump off the ice and hunt for food. Polar bears have to swim and find these floating pieces of ice. These days, they have to swim farther to find the floating ice. Many of them don’t have enough energy. They get too tired, and they die in the water. Polar bears are suffering because of other problems, too. Pollution makes their water dirty. Many countries go to the North Pole to look for oil and gas, and they damage the environment of the bears. In addition, when ships sail through the North Pole, they cause a lot of damage. Finally, people hunt and kill too many polar bears. However, melting ice is definitely the biggest problem. Right now, there are about 25,000 polar bears in the world. If global warming continues, there may be only about 12,000 in the year 2050. By the year 2080, that number might be much smaller. It is important to study polar bears. When we learn about polar bears, we also learn about the health of the North Pole. If polar bears are doing well, then the environment in the North Pole is probably healthy. If polar bears are suffering then there are probably serious problems in the North Pole. Right now, governments around the world are working to help polar bears. There are new laws that protect polar bears. However, if global warming continues to get worse, polar bears may disappear forever.

Strengthening Your Core
If there is one indication that someone is fit, it is a tight and lean stomach. Men and women alike hope that eating right and putting in hard work at the gym will earn them a perfect six-patch. Unfortunately, the opposite is also true. The rising popularity of fast food has led to an increase of obesity rates and waistlines around the globe. If someone is out of shape, you will notice the extra weight around their midsection. In both cases, a person’s core muscles seem to tell a lot about their fitness and eating habits. Many people associate the core with just the stomach area, but science actually defines it as our body without arms and legs. Although many people want a solid core to look good, the development of these muscles affects many areas of our lives. In athletics and general life for that matter, we all rely on our core muscles heavily to get things done. Studies have shown that athletes who build a powerful core foundation aren’t injured as much. Meanwhile, the benefits of your average Joe may be even greater. Ordinary people use their core muscles for nearly every task they do. This includes picking things up, sitting in a chair, or tying your shoes. Our core muscles provide stability, so we can keep our balance and easily move in any direction. If we neglect them, life can become much more difficult. As a result, we should always consider our core muscles when designing our workouts. However, if you have been sedentary for years, performing thousands of repetitions will probably get you injured. Instead, start off slowly and gradually build up your numbers. An excellent exercise for both beginners and advanced exercisers is the plank. You simply get in an extended pushup position as if you have just finished a rep. Maintain this position, but place the weight on your forearms instead of your hands. Then, hold the position as long as you can. You should feel your core muscles working hard to help your hands and support the weight of your body. In the beginning, you may only be able to hold it for a few seconds, but keep at it. The Guinness World Record for abdominal planking is three hours and seven minutes.

The Most Convenient Way to Shop
Do you do a lot of online shopping? For millions of people, it is a wonderful way to purchase the things they want without having to leave their homes. Online shopping is not very old. The first online shopping company was created in 1991. However, the idea of shopping from home has existed for a very long time. Many years ago, people shopped with mail-order catalogues. A catalogue is a very thin magazine that is full of advertisements, and then they mailed their order back to the company. A few weeks later, their product arrived. Because people ordered their products through the mail, they were called “mail-order” catalogues. After that, shopping television shows became popular. These TV shows introduced products to people watching at home. People who wanted to buy something called the company and placed the order. This is called home shopping. Now we have online shopping. Online shoppers go online and look at web sites. When they find something they want, they place an order with the web site. They usually pay with a credit card or with virtual currency. Online shopping is changing shopping. Millions of people buy things online every day. The biggest effect of online shopping is on stores. As more people buy things online, more stores are shutting down. After all, why should you go to a store if you can buy things from home? The main advantage of online shopping is convenience. You can buy almost anything from anywhere in the world, and a week later the product will be in your house. Also, other customers write reviews of products. You can read these reviews and decide whether or not you want to buy the product. The big disadvantages are the loss of jobs from store closing, and the fact that you can’t examine an item closely before you buy it. After online shopping, what do you think will come next?
