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.

Though called by sweet-sounding names like Firinga or Katrina, tropical cyclones are huge rotating storms 200 to 2,000 kilometers wide with winds that blow at speeds of more than 100 kilometers per hour (kph). Weather professionals know them as tropical cyclones, but they are called hurricanes in the Caribbean Sea, typhoons in the Pacific Ocean, and cyclones in the Indian Ocean. They occur in both the northern and southern hemispheres. Large ones have destroyed cities and killed hundreds of thousands of people.

Tropical cyclones begin over water that is warmer than 27 degrees Celsius (80 degrees Fahrenheit) slightly north or south of the earth’s equator. Warm, humid air full of water vapor moves upward. The earth's rotation causes the growing storm to start to rotate around its center (called the eye). At the certain height, the water vapor condenses, changing to liquid and releasing heat. The heat draws more air and water vapor upward, creating a cycle as air and water vapor rise and liquid water falls. If the cycle speeds up until winds reach 118 kilometers per hour, the storm qualifies as a tropical cyclone.

Most deaths in tropical cyclones are caused by storm surge. This is a rise in sea level, sometimes seven meters or more, caused by the storm pushing against the ocean's surface. Storm surge was to blame for the flooding of New Orleans in 2005. The storm surge of Cyclone Nargis in 2008 in Myanmar pushed seawater nearly four meters deep some 40 kilometers inland, resulting in many deaths.

According to the passage, tropical cyclones are called typhoons in________.

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.

Space Debris
Once something is considered rubbish, we want to throw it away and forget about it. Yet if we are not careful about where we store it, our garbage could come back to haunt us. On the Earth, poorly discarded garbage can cause land, water, and air pollution. And now, people are starting to learn that space debris can also cause a host of different problems. Space debris is defined as a collection of objects that orbit the Earth. Space debris can be classified into two categories. One is man-made rubbish, such as old satellites, rockets, and other machinery left in space after past missions. The other is natural objects, such as meteors that are traveling through space. If you think the man-made garbage doesn’t amount to much, guess again. Researchers estimate that there are over 20,000 pieces of large debris floating around in space and approximately 300,000 smaller pieces in orbit as well. Traveling at speeds of up to 17,500 miles per hour, these objects create a great degree of danger for any spaceships when they leave or return to the Earth. We are lucky to some degree that there haven’t been too many accidents caused by space debris as of yet. Still some incidents have occurred. In 1996, a French satellite was damaged after it crashed into debris from an old French rocket. Then in 2009, an old Russian satellite collided with a working US satellite. The end result was an additional 2,000 pieces of space junk that was added to the junk pile. As the current situation can only worsen, it is now up to the international community to cooperate and create a plan to deal with space debris. For starters, several nations have pledged to take more care with the items they discard in space to cut down on future debris. Researchers are working on devising a way to label space junk, so it can be avoided. Others have proposed more creative techniques to recapture the garbage and discard it on the Earth, or destroy it with lasers. The nightmare scenario that everyone fears is if the Kessler Syndrome starts to occur. This is when the density of garbage becomes so high that it sets off a chain reaction of collisions which would raise the probability of accidents even further. Although there is not a long-term solution in place for space debris, nations are starting to understand the seriousness of this problem.

Drawing a Line in the Sand
Artists are known to be a picky bunch. Over years of practice, they often develop a preference for certain materials. For instance, some sculptors will only work with marble, whereas some painters may insist on only using watercolour paints. Yet, only a select few have become masters working with a common material that you can find on any beach: sand. As children, we all made sand castles, but some skilled artists have taken this activity to the next level. They have created impressive, massive sand constructions in the shape of dragons, castles, and everything else you can imagine. A major benefit for many artists who build with sand is its simplicity. To get started, all you need is sand and water. However, mastering this medium takes years of practice and great attention to detail. For example, different tasks require different ratio of water to sand to get the job done. Deciding on the proper tools can also be complicated. Some artists prefer using buckets and shovels, while others are purists who refuse to use anything but their hands. Sand painting is another form of sand art. The practice dates back dozens of thousands of years and has been used by several different cultures. It involves spreading different coloured particles, which often come from crystals and rocks, onto a surface and then arranging them to make a picture. Interestingly enough, many sand paintings are designed to be temporary. Tibetan monks will spend days creating beautiful sand paintings which are blown away by winds shortly after they are finished. They view the natural destruction of their work as a symbol of impermanence in life. Meanwhile, Native Americans consider their temporary sand paintings as living creatures and they treat them with great respect while they exist. Recently, filmmakers have also discovered a way to work with sand by creating sand animation. Like other forms of animation, an artist will create one image and then capture it on camera. Then, they will make some subtle changes and then move on to the next frame and so on. After they have created and captured hundreds of images, the frames will be strung together. In the final product, it will appear as if the sand images are moving or changing shape. The next time you are at the beach, let your mind run free as you look at the shore. Who knows, you might get the urge to create some remarkable sand art of your own.
5. The term “impermanence” considered by Tibetan monks is based on the idea that ___________

Niagara Falls, one of the most famous North American natural wonders, has long been a popular tourist destination. Tourists today flock to see the two falls that actually constitute Niagara Falls: the 173-foot-high Horseshoe Falls on the Canadian side of the Niagara River in the Canadian province of Ontario and 182-foot-high American Falls on the U.S. side of the river in the state of New York. Approximately 85 percent of the water that goes over the falls actually goes over Horseshoe Falls, with the rest going over American Falls.
Most visitors come between April and October, and it is quite a popular activity to take a steamer out onto the river and right up to the base of the falls for a close-up view. It is also possible to get a spectacular view of the falls from the strategic locations along the Niagara River, such as Prospect Point of Table Rock, or from one of the four observation towers which have heights up to 500 feet.
Tourists have been visiting Niagara Falls in large numbers since the 1800’s; annual visitation now averages above 10 million visitors per year. Because of concern that all these tourists would inadvertently destroy the natural beauty of this scenic wonder, the State of New York in 1885 created Niagara Falls Park in order to protect the land surrounding American Falls.
A year later Canda created Queen Victoria Park on the Canadian side of the Niagara, around Horseshoe Falls. With the area surrounding the falls under the jurisdiction of government agencies, appropriate steps could be taken to preserve the pristine beauty of the area.
