Piranhas on Parade
With the exception of whales and sharks, fish are generally considered to be harmless creatures. The thought of a small fish hurting anyone is almost laughable. However, piranhas are an exception to this rule. They frequently attack in groups and in some cases they can cause great bodily harm. Most piranhas are under 25 centimetres long, but don’t let their size fool you. Unlike most fish, they have two rows of razor-sharp teeth. Their triangular shape makes them perfect for puncturing and shredding whatever they bite. Although piranhas usually swim alone, they also hunt in school of 1,000 fish or more, which greatly multiplies the damage they are capable of. As small fry, they feed of vegetables and plankton until they can tolerate meat. In terms of flesh, they will eat any animals or fish that enters their territory when swimming in schools, even humans. In some cases, hungry piranhas will even go after each other if they are really desperate for a snack. However, the danger they present to humans is often exaggerated. In Hollywood films, piranhas are often portrayed as vicious destroyers who love to eat people. Some rumours even developed that schools of hungry piranhas will quickly kill and consume humans in a matter of seconds. In reality, the majority of these attacks only consist of a few painful, but non-life threatening bites to the person. However, that is not always the case. A recent attack on December 25, 2013 in Argentina left at least 60 people injured. Victims were wading in a river when a sudden attack began. Local police believe that some local debris left floating by fishermen brought the piranhas to the area. Many swimmers left the water with cuts all over their bodies, and a few even had to have their limbs amputated. Oddly enough, some people choose to keep piranhas in their home aquariums. However, piranhas can be tough to catch for this purpose because their sharp teeth can easily cut through fishing nets. Before buying one, be sure to check local laws as it is illegal to own them in many areas. Lawmakers often fear of the damage piranhas can cause to marine life if an owner decides to release them into a local stream.
2. Which of the following best matches the meaning of the word “puncturing” in paragraph 2?A. burying
B. hiding
C. filling
D. poking

Microwave Magic
The 20th century was a time in which many great inventions were created. Things like the automobile, computers, and the Internet truly changed the way we live forever. Yet, one handy invention that has made eating at home far more convenient is often overlooked. The invention of microwave allowed even the worst cooks in the world to prepare a meal in essentially no time at all. What is really fascinating about microwave ovens is that they were invented by accident. During World War II, British scientists discovered a device called a magnetron that can produce microwaves. They hoped it would help them quickly identify German planes that were intent on bombing their nation. However, it would be an American scientist named Percy Spencer who linked microwaves with cooking food. One day, Spencer brought a candy bar with him to work, and he stored it in his shirt pocket. While walking through a radar set, he noticed that the radar had somehow melted his treat. Afterwards, Spencer and his coworkers started to experiment with heating other things. They tried heating some popcorn kernels and it worked like a charm. Next, they tried to cook an egg with microwaves, but it literally blew up in their face. In 1945, the company that Spencer worked for, Raytheon, filed a patent for the technology and started working on ways to make microwave ovens more efficient. The first commercial microwave ovens hit the market, and an industry was born. In the first few years, things didn’t appear too promising. Early microwaves were quite expensive and they were big and chunky, so it was difficult to fit them in most kitchens. Yet, people did see the benefit an ease of being able to cook foods so quickly. Therefore, once manufacturers were able to shrink the device and bring down the price a bit, sales started to skyrocket. By 1986, approximately 25 percent of Americans had a microwave oven in their kitchen. Through the years, many people have questioned the safety and potential negative health effects of microwaves, fearing that the technology was a little too good to be true. Yet, some studies have shown that microwaving food actually helps it to retain more nutrients because of the short cooking times and minimal water required. However, it is essential to use microwave containers to avoid harmful chemicals from possibly leaking into your food. Microwave dishes may never be seen as gourmet cooking, but when you are in a hurry, nothing beats this method of cooking.
8. It can be inferred from the passage that when we use microwave ovens _________A. we need special containers
B. we consume a lot of energy
C. the food we cook has to have many nutrients
D. fewer people will use them in the near future

The LED Lighting Revolution
If you have picked up any electronics magazines recently, you have probably heard about LEDs; yet chances are, you probably don’t realize why they are so special. The truth is that these tiny light bulbs are helping to improve watches, remote controls, televisions, and a host of other projects. Diodes are components that enable energy to flow in one direction, while simultaneously blocking the current from the opposite direction. This is similar to how a valve works on a faucet. If electronic manufacturers require currents to flow in several directions, then multiple diodes will be included in the circuit design. With LEDs, every time a current passes through them, a light is emitted. LED is short for light-emitting diode. Although they have only recently waves in the past decade or so, early models have been around since 1962. There are several benefits that LEDs offer when compared to incandescent or fluorescent lighting. For starters, they have extremely long-life spans in the range of l00,000 hours even in the toughest conditions. They also require far less energy than power sources, which can save users money over the long run. Since LEDs don’t contain moving parts like other bulbs, they can withstand heavy impacts without getting damaged. Finally, they don’t require any _warm-up time_ so they instantly light up when switched on. The only drawback is that they are still a more expensive to purchase at the moment. LEDs were first used on digital clocks, but they have come a long way since then. They have certainly done a lot to improve TV technology. LED TVs have been a hit because they can be built extremely thin, yet also offer power-saving benefits. LED TVs also provide a wider range of colour, which allows for more lifelike and vivid images. In the future, organic LEDs, or OLEDs, will bring additional benefits for viewers. OLEDs are even more flexible than LEDs, so manufacturers will be able to create bent display screens and lights. Therefore, you will be able to roll up your living room TV set and pack it in your suitcase. In other words, LED and OLED technology will likely be lighting up your life for years to come.
8. The tone of the passage is ________A. negative
B. subjective

Therefore, you will be able to roll up your living room TV set and pack it in your suitcase. In other words, LED and OLED technology will likely be lighting up your life for years to come.
4. The word “_this_” in paragraph 2 refers to ________A. flowing in only one direction
B. working of a faucet
C. blocking the current
D. supplying energy

The LED Lighting Revolution
If you have picked up any electronics magazines recently, you have probably heard about LEDs; yet chances are, you probably don’t realize why they are so special. The truth is that these tiny light bulbs are helping to improve watches, remote controls, televisions, and a host of other projects. Diodes are components that enable energy to flow in one direction, while simultaneously blocking the current from the opposite direction. This is similar to how a valve works on a faucet. If electronic manufacturers require currents to flow in several directions, then multiple diodes will be included in the circuit design. With LEDs, every time a current passes through them, a light is emitted. LED is short for light-emitting diode. Although they have only recently waves in the past decade or so, early models have been around since 1962. There are several benefits that LEDs offer when compared to incandescent or fluorescent lighting. For starters, they have extremely long-life spans in the range of l00,000 hours even in the toughest conditions. They also require far less energy than power sources, which can save users money over the long run. Since LEDs don’t contain moving parts like other bulbs, they can withstand heavy impacts without getting damaged. Finally, they don’t require any _warm-up time_ so they instantly light up when switched on. The only drawback is that they are still a more expensive to purchase at the moment. LEDs were first used on digital clocks, but they have come a long way since then. They have certainly done a lot to improve TV technology.

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.
8. Which of the following can provide the better durability with the technique called electrospinning?A. High voltage
B. New material
C. A strand of nanofiber

Fighting Back against Bullying
It is often said that childhood is the most joyful period in a person’s life. This is supposed to be a time when children can focus on their studies and enjoy their free time with friends. However, these days more and more children are experiencing a stressful and miserable adolescence due to bullying. Bullying occurs when one student, or a group of students, uses aggression to harm another child and try to make them feel bad. This abuse can either be physical, such as pushing or beating another student, or it could take the form of mental abuse, such as taunting and teasing the student. Although it may seem harmless to some, studies show that bullying can greatly impact a child’s life and have long-lasting negative effects. People who have been bullied may experience self-esteem issues and start to lack confidence in almost everything they do. These traits can make it difficult to manage relationships and even cause them to have trouble holding down a steady job. One of the most harmful types of bullying that is on the rise is cyberbullying. The bullied student is targeted in cruel or threatening e-mails, instant messages, or hateful public posts about them. In many cases, bullies will post embarrassing pictures of the victim or spread nasty rumors about them through social media. In some tragic cases, children have even turned to suicide, feeling that they can’t deal with the humiliation. If you are being bullied by another student, you don’t have to accept it or suffer. There are some steps you can take to deal with the problem. At first, you may try to ignore the bully, as they will often lose interest in bothering you if you don’t react. If the bullying persists, however, you should tell a trusted adult as soon as possible. This could be a parent, a family friend, a teacher, a school guidance counselor, or even the school principal. Until recently, many teachers and school officials turned a blind eye to bullying, believing that the students would eventually sort it out by themselves. But this mindset has changed in recent years in light of some of the tragedies that have occurred. If for any reason you feel that your complaints are not being taken seriously, there are other groups available online who will help you deal with bullying. By dealing with bullying at an early stage, you can stop it before it gets much worse.
7. Nowadays, the community has ________A. taken notice of the problem of bullying more seriously

Until recently, many teachers and school officials turned a blind eye to bullying, believing that the students would eventually sort it out by themselves. But this mindset has changed in recent years in light of some of the tragedies that have occurred. If for any reason you feel that your complaints are not being taken seriously, there are other groups available online who will help you deal with bullying. By dealing with bullying at an early stage, you can stop it before it gets much worse.

Fighting Back against Bullying
It is often said that childhood is the most joyful period in a person’s life. This is supposed to be a time when children can focus on their studies and enjoy their free time with friends. However, these days more and more children are experiencing a stressful and miserable adolescence due to bullying. Bullying occurs when one student, or a group of students, uses aggression to harm another child and try to make them feel bad. This abuse can either be physical, such as pushing or beating another student, or it could take the form of mental abuse, such as taunting and teasing the student. Although it may seem harmless to some, studies show that bullying can greatly impact a child’s life and have long-lasting negative effects. People who have been bullied may experience self-esteem issues and start to lack confidence in almost everything they do. These traits can make it difficult to manage relationships and even cause them to have trouble holding down a steady job. One of the most harmful types of bullying that is on the rise is cyberbullying. The bullied student is targeted in cruel or threatening e-mails, instant messages, or hateful public posts about them. In many cases, bullies will post embarrassing pictures of the victim or spread nasty rumors about them through social media. In some tragic cases, children have even turned to suicide, feeling that they can’t deal with the humiliation. If you are being bullied by another student, you don’t have to accept it or suffer. There are some steps you can take to deal with the problem. At first, you may try to ignore the bully, as they will often lose interest in bothering you if you don’t react. If the bullying persists, however, you should tell a trusted adult as soon as possible. This could be a parent, a family friend, a teacher, a school guidance counselor, or even the school principal.

Incredible Shrinking Microchips
There is a popular old saying that “bigger is better”. Although this may be true in some regards, the exact opposite often applies in technology. As electronic components get smaller, it allows companies to manufacture tinier devices with more features. Thus began the never-ending quest to create the smallest microchips on the planet. Yet as these vital electronic components get smaller, they are also getting stronger and clever inventors are finding new ways in which to use them to do incredible things. Currently, the biggest limitation microchip producers face when trying to reduce chips’ size is the copper wires that provide electrical current throughout the chip. Although they can be made smaller, this can cause a whole host of problems such as melting and overheating. Thanks to the work of a few scientists from the UK though, this problem may soon be a thing of the past. Their solution is getting rid of the copper wiring altogether and using carbon nanotubes instead. Not only would this allow for smaller sizes but it would also increase the power that microchips can generate. In the end, this would translate into smaller and more powerful devices much to the delight of consumers all over the world. Corporate powerhouse Intel® has announced plans to create a line of tiny, low power chips that can be used in bracelets, smart watches, and other tiny devices. The chips will be called Intel® Quark, and they are being designed primarily to fit in biomedical devices. A key selling point to biomedical technology is that the devices have to be nonintrusive because people don’t want to carry around heavy equipment to monitor their health. If they can do this, Intel® will likely find several tablet and smartphone manufacturers who are willing to corporate Quark microchips into their devices. In a somewhat unusual project, researchers are working on a special microchip that will serve as miniature human organs in experiments. These “organ” chips could be used to test different medicines and study diseases. If realized, the technology could put an end to the use of lab mice and other animals for testing. Everyone from the largest pharmaceutical companies to the US military has shown interest in the project. Currently, the research team in charge of the project believes that within five years the organ chips will be used in practical research. It goes to show that thinking small often produces the biggest results.
8. Which of the following is NOT the benefit of the “organ” chips?A. To serve as miniature human organs in experiments
B. To be used to test different medicines and study diseases
C. To be likely useful in practical research
D. To put an end to the use of labs for testing medicines

The Rise of E-books
Over the past decade, e-books have revolutionized the way people consume written formation. It will probably come as no surprise the total global sales number continues to rise each year. There are several reasons why readers are buying more e-books. For starters, reading a lengths e-book in front of your computer isn't the most comfortable thing to do. But since tablet sales have exploded, readers can now relax and read their favourite e-books in bed from the beach. Many e-books are often sold at lower prices than traditional books. Since there is almost zero cost for producing e-books, some authors are offering their novels at lower prices. Another factor is convenience. In the past, keeping a large book collection meant setting aside a lot of extra space in one's home. With e-books, it is now possible for readers to carry a portable library, which contains thousands of books. To really understand e-book market though, it is important to keep up with national trends. Recent data suggests that the e-book market in the US and the UK have matured. In both of these countries, e-book sales account for roughly 20 percent of overall book sales. Although that percentage continues to increase, it is going up at a slower rate than in the past. The popularity of e-books has exploded in Russia. In one poll, 70 percent of Russians claim to have read at least one e-book. However, publishers are not too pleased with this new because approximately 92 percent of e-books in Russia are acquired illegally. In France, consumers don't appear to be loo keen on e-books at this time. Although in 2012, e-book sales comprised about 3 percent of the market, it is predicted that this number will increase at a very slow pace. Some French people believe that reading e-books on small screens is uncomfortable. Others say that the French are a cultural exception, as they like the feeling of holding a dusty old physical book. This demonstrates that no matter how popular e- books get, it is unlikely that traditional books will disappear any time soon.
7. What is the meaning of the last sentence of the passage?A. French people will change their minds about e-books.
B. Some people will continue to read traditional books.
C. It is just a matter of time before e-books disappear.
D. E-books won’t get popular in France until screens get bigger.
