Have you ever noticed that our machines are getting smaller? Cell phones, cameras, computers and everything else look smaller every year. One kind of new science involves machines that are smaller than we can imagine. The name of this science is nanotechnology. Nanotechnology means doing science, engineering, and technology at a very very small level. In other words, nanotechnology is the science of tiny things. But how tiny is the science of nanotechnology? In nanotechnology, scientists work with things that are the size of a nanometer. One meter has one billion nanometers. Here is another way to describe nanotechnology: it is the science of observing and controlling individual atoms and molecules. Nanotechnology is a new word, but the idea of studying atoms and molecules has existed for a long time. In 1959, an American scientist Richard Phillips Feynman gave a speech in which he claimed that we can see and control molecules and atoms. About ten years later, a Japanese professor came up with the term “nanotechnology”. Because nanotechnology is so new, we are only starting to understand how we can use it. Nanotechnology could be very useful in medicine. In the future, doctors may use nanotechnology to help with organ transplants. An organ transplant is the act of putting an organ into another person’s body. Scientists think that with nanotechnology, they might be able to make a person’s body accept a foreign organ. Nanotechnology might also help doctors fight infections, find diseases in patients, and deliver medicine to the right spot in patients’ bodies. Nanotechnology might also be useful in protecting the environment. It might be able to help us save energy, reduce waste, and keep water clean. For example, nanotechnology might be able to make some materials such as steel stronger. If we have stronger steel, we will be able to use it longer. That way, we can produce less steel and save our resources. Nanotechnology might be useful in so many ways. This science of studying tiny things could change the world.
1. Around what year did people start using the word “nanotechnology”?

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:
Glass is a remarkable substance made from the simplest raw materials. It can be colored or colorless, monochrome or polychrome, transparent, translucent, or opaque. It is lightweight impermeable to liquids, readily cleaned and reused, durable yet fragile, and often very beautiful. Glass can be decorated in multiple ways and its optical properties are exceptional. In all its myriad forms - as table ware, containers, in architecture and design - glass represents a major achievement in the history of technological developments.
Since the Bronze Age about 3,000 B.C., glass has been used for making various kinds of objects. It was first made from a mixture of silica, line and an alkali such as soda or potash, and these remained the basic ingredients of glass until the development of lead glass in the seventeenth century. When heated, the mixture becomes soft and malleable and can be formed by various techniques into a vast array of shapes and sizes. The homogeneous mass thus formed by melting then cools to create glass, but in contrast to most materials formed in this way (metals, for instance), glass lacks the crystalline structure normally associated with solids, and instead retains the random molecular structure of a liquid. In effect, as molten glass cools, it progressively stiffens until rigid, but does so without setting up a network of interlocking crystals customarily associated with that process. This is why glass shatters so easily when dealt a blow. Why glass deteriorates over time, especially when exposed to moisture, and why glassware must be slowly reheated and uniformly cooled after manufacture to release internal stresses induced by uneven cooling.
Another unusual feature of glass is the manner in which its viscosity changes as it turns from a cold substance into a hot, ductile liquid. Unlike metals that flow or "freeze" at specific temperatures glass progressively softens as the temperature rises, going through varying stages of malleability until it flows like a thick syrup. Each stage of malleability allows the glass to be manipulated into various forms, by different techniques, and if suddenly cooled the object retains the shape achieved at that point. Glass is thus amenable to a greater number of heat-forming techniques than most other materials.

Why does the author list the characteristics of glass in paragraph 1?

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:
There are three valid arguments to support the preservation of endangered species. Aesthetic justification contends that biodiversity contributes to the quality of life because many of the endangered plants and animals are particularly appreciated for their unique physical beauty. The aesthetic role of nature in all its diverse forms is reflected in the art and literature of every culture attaining symbolic status in the spiritual life of many groups. According to the proponents of the aesthetic argument, people need nature in all its diverse and beautiful forms as part of the experience of the world.
Another argument that has been put forward, especially by groups in the medical and pharmacological fields, is that of ecological self-interest. By preserving all species, we retain a balance of nature that is ultimately beneficial to humankind. Recent research on global ecosystems has been cited as evidence that every species contributes important or even essential functions that may be necessary to the survival of our own species. Some advocates of the ecological argument contend that important chemical compounds derived from rare plants may contain the key to a cure for one of the diseases currently threatening human beings. If we do not protect other species, then they cannot protect us.
Apart from human advantage in both the aesthetic and ecological arguments, the proponents of a moral justification contend that all species have the right to exist, a viewpoint stated in the United Nations World Charter for Nature, created in 1982. Furthermore, if humankind views itself as the stewards of all the creatures on Earth, then it is incumbent upon human beings to protect them, and to ensure the continued existence of all species. Moral justification has been extended by a movement called “deep ecology,” the members of which rank the biosphere higher than people because the continuation of life depends on this larger perspective. To carry their argument to its logical conclusion, all choices must be made for the biosphere, not for people.

Where in the passage does the author explain how rare species contribute to the health of the human species?

Read the following passage and choose the best answer (A, B, C, D):
For many American university students, the weeklong spring break holiday means an endless party on a sunny beach in Florida or Mexico. In Panama City Beach, Florida, a city with a permanent population of around 36,000, more than half a million university students arrive during the month of March to play and party, making it the number one spring break destination in the United States. A weeklong drinking binge is not for anyone, however, and a growing number of American university students have found a way to make spring break matter. For them, joining or leading a group of volunteers to travel locally or internationally and work to show problems such as poverty, homelessness, or environmental damage makes spring break a unique learning experience that university students can feel good about. Students who participate in alternative spring break projects find them very rewarding. While most university students have to get their degrees before they can start helping people, student volunteers are able to help people now. On the other hand, the accommodations are far from glamorous. Students often sleep on the floor of a school or spend the week camping in tents. But students only pay around $250 for meals and transportation, which is much less than some of their peers spend to travel to more traditional spring break hotspots. Alternative spring break trips appear to be growing in popularity at universities across the United States. Students cite a number of reason for participating. Some appreciate the opportunity to socialize and meet new friends. Others want to exercise their beliefs about people’s obligation to serve humanity and make the world a better place. Whatever their reason, these students have discovered something that gives them rich rewards along with a break from school work.

Read the following passage and choose the best answer (A, B, C, D):
Cities develop as a result of functions that they can perform. Some functions result directly from the a great city regardless of the disadvantageous ingenuity of the citizenry, but most functions activity. result from the needs of the local area and of the surrounding hinterland (the region that supplies goods to the city and to which the city furnishes services and other goods). Geographers often make a distinction between the situation and the site of a city. Situation refers to the general position in relation to the surrounding region, whereas site involves in physical characteristics of the specific location. Situation is normally much more important to the continuing prosperity of a city. If a city is well situated in regard to its hinterland, its development is much more likely to continue. Chicago, for example, possesses an almost unparalleled situation: it is located at the southern end of a huge lake that forces East-West transportation lines to be compressed into its vicinity, and at a meeting of significant land and water transport routes. It also overlooks what is one of the world's fiest large farming regions. These factors ensured that Chicago would become characteristics of the available site, such as being prone to floding during thunderstorm Similarly, it can be argued that much of New York City's importance stems from its early and continuing advantage of situation. Philadelphia and Boston both originated at about the same time as New York and shared New York's location at the Western end of one of the world's most important oceanic trade routes, but only New York possesses an easy-access functional connection (the Hudson-Mohawk lowland) to the vast Midwestern hinterland. This account does not alone explain New York's primacy, but it does include several important factors. Among the many aspects of situation that help to explain why some cities grow and others do not, original location on a navigable waterway seems particularly applicable. Of course, such characteristics as slope, drainage, power resources, river crossings, coastal shapes, and other physical characteristics help to determine city location, but such factors are normally more signifiant in early stages of city development than later.

Read the following passage and choose the best answer (A, B, C, D):
William Sydney Porter (1862-1910), who wrote under the pseudonym of O. Henry, was born in North Carolina. His only formal education was to attend his Aunt Lina’s school until the age of fifteen, where he developed his lifelong love of books. By 1881 he was a licensed pharmacist. However, within a year, on the recommendation of a medical colleague of his Father’s, Porter moved to La Salle County in Texas for two years herding sheep. During this time, Webster’s Unabridged Dictionary was his constant companion, and Porter gained a knowledge of ranch life that he later incorporated into many of his short stories. He then moved to Austin for three years, and during this time the first recorded use of his pseudonym appeared, allegedly derived from his habit of calling “Oh, Henry” to a family cat. In 1887, Porter married Athol Estes. He worked as a draftsman, then as a bank teller for the First National Bank. In 1894 Porter founded his own humor weekly, the “Rolling Stone”, a venture that failed within a year, and later wrote a column for the Houston Daily Post. In the meantime, the First National Bank was examined, and the subsequent indictment of 1886 stated that Porter had embezzled funds. Porter then fled to New Orleans, and later to Honduras, leaving his wife and child in Austin. He returned in 1897 because of his wife’s continued ill-health, however she died six months later. Then, in 1898 Porter was found guilty and sentenced to five years imprisonment in Ohio. At the age of thirty five, he entered prison as a defeated man; he had lost his job, his home, his wife, and finally his freedom. He emerged from prison three years later, reborn as O. Henry, the pseudonym he now used to hide his true identity. He wrote at least twelve stories in jail, and after re-gaining his freedom, went to New York City, where he published more than 300 stories and gained fame as America’s favorite short Story writer. Porter married again in 1907, but after months of poor health, he died in New York City at the age of forty-eight in 1910. O. Henry’s stories have been translated all over the world.

Helpful Home Remedies
When something is bothering us, it is natural to try and make it go away. We might head to the doctor or make a trip to the local pharmacy for medicine. Unfortunately, these methods can be time-consuming and expensive. But have no fear, because you might be able to whip up an effective home remedy with nothing more than a few simple ingredients from your cupboard. At one time or another, it seems everyone comes down with flu. Our temperature will rise, we may feel nauseous, and we will likely have a stuffy nose and a cough. Aside from taking it easy and getting plenty of rest, you can turn to chicken soup to make you feel better. Mothers from around the world have been making it for thousands of years for sick relatives. The hot soup warms you up and its flavorful smell helps to clear up your nose. It is often prepared with garlic, onions, and carrots which all provide vitamins that increase circulation and reduce inflammation. In addition, the liquid will keep you hydrated. Last but not least, it is usually delicious. Nothing drives people mad quite like getting the hiccups. If you are fortunate, they will only last for a few minutes. Yet in some cases, nothing seems to drive them away. Next time you have a bad case of the hiccups, try this sweet solution. Take a full teaspoon with sugar and swallow it down. The sugar is thought to change instructions to your nerves and get your throat muscles to relax. Just don’t overdo it, or else you might have to go to the dentist to get some cavities fixed. Headaches are another annoyance that we can do all without. If you get one, try this home remedy which doesn’t require taking any food or liquids at all. Instead, try putting a pencil in between your teeth. A major cause of headache is stress, and when we are anxious, we often tighten our jaws, which strains a muscle that connects to the temples of our head, and this action causes the pain. By placing a pencil in our mouths, we are giving our minds a signal to relax our jaw. This can reduce the intensity of headaches almost immediately. Just remember not to bite down, unless you are in the mood for a lead sandwich.

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.
6. What does the author think is the most likely energy solution for the future?
