Ocean Currents and the Turning of the Tide
If you take a seat at the beach and look out across the water, you’ll soon notice that oceans have a rhythm of their own. Throughout the course of the day, sea levels will rise and fall, and water will flow through routes and end up in different places. But how does it all work? One force at play is tides, which are the alternating water levels of the ocean. There are two major gravitational forces which cause tides: the sun and the moon. The moon’s force has a tugging effect on oceans which causes them to bulge outwards on opposite sides of the planet. Solar tides operate according to the same principles. However, they are only about 50 percent as strong due to the distance between the sun and the earth. As tides rise and fall, they create tidal currents. The strongest tidal currents occur at the height of both high and low tides. Unlike other currents, they do not flow in a continuous stream. Far from shore, tidal currents don’t have much of an effect. Yet when they pass through narrow area, like harbours and bays, tidal currents can displace plants, animals, and sediment. Although they may certainly shake things up, not all of the damage is negative. Tidal currents can spread fish eggs across long distances to assist fertilization, in addition to transporting key nutrients. Another category of currents is ocean currents. These currents occur near the top of the water, and are mainly powered by the wind. One example of these is coastal currents, which are those beachgoers encounter when going for a swim. One of the strongest and most well-known currents is the Gulf Stream, which brings warm water from the Gulf of Mexico all the way to Western Europe. Meanwhile, Deep Ocean currents are a powerful force in the depths of oceans. The strongest of these has been nicknamed the global conveyor belt, and it moves much slower than surface currents. Although we can’t see it in operation, it’s about 16 times as powerful as all the earth’s rivers put together. As the global conveyor belt pushes water around the planet, it carries nutrition and carbon dioxide to places that truly need them. In the end, although there are several currents working on oceans simultaneously, they each seem to perform a necessary function that creates balance for life in the sea.

A Picture Is Worth a Thousand Words
In 1826, a man named Joseph Nicephore Niepce went to the upstairs window of his home in France. He used a new invention called a camera to take the world’s first photograph of nature. Niepce’s photograph shows us the view from his window. However, it is very difficult to know that when you look at the picture. The image is not very clear at all. That doesn’t matter. On that day, Niepce changed the world forever. Photography first became very popular in the 1850s and 1860s. People liked it because it showed more details than other kinds of art. A painting or a statue might be more beautiful than a photograph, but a photograph can tell you a much clearer story. Many people believe that colour photographs didn’t exist until the 1920s, but that’s not true. The first colour photograph was taken in 1855. It shows a colourful ribbon. Before the 1920s, people didn’t often use colour photography because it was very complicated and expensive. Even after colour photography became easier and cheaper, many people still preferred black and white pictures. They felt that black and white had a more “classic photo” feeling. In the 1940s, colour photography finally replaced black and white. When we think of the history of photography, it is amazing to think of how easy it is to take pictures today. Many years ago, only professionals had cameras. These days, just about everybody has one. One of the biggest reasons for this change is the popularity of smartphones. Almost every modern smartphones. Almost every modern smartphone has a camera. These smartphone cameras are very easy to use and they also take very clear pictures. Most of them have a video function.  One thing that hasn’t changed is the importance of photography. These days, a picture can still create all kinds of feelings and emotions inside of us. There is a saying. “A picture is worth a thousand words.”

"The nuclear family, consisting of a mother, father, and their children, may be more an American ideal than an American reality. Of course, the so-called traditional American family was always more varied than we had been led to believe, reflecting the very different racial, ethnic, class, and religious customs among American groups.
 The most recent government statistics reveal that only about one third of all current American families fit the traditional mold and another third consists of married couples who either have no children or have none still living at home. Of the final one, about 20 percent of the total number of American households are single people, usually women over sixty-five years old. A small percentage, about 3 percent of the total, consists of unmarried people who choose to live together, and the rest, about 7 percent, are single, usually divorced parents, with at least one child. Today, these varied family types are typical, and therefore, normal. Apparently, many Americans are achieving supportive relationships in family forms other than the traditional one."

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?

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?

Read the following passage and choose the best answer (A, B, C, D):
Of all modern instruments, the violin is apparently one of the simplest. It consists in essence of a hollow, varnished wooden sound box, or resonator, and a long neck covered with a figerboard, along which four strings are stretched at high tension. The beauty of design, shape, and decoration is no accident: the proportions of the instrument are determined almost entirely by acoustical considerations. Its simplicity of appearance is deceptive. About 70 parts are involved in the construction of a violin. Its tone and its outstanding range of expressiveness make it an ideal solo instrument. No less important, however, is its role as an orchestral and chamber instrument. In combination with the larger and deeper- sounding members of the same family, the violins form the nucleus of the modern symphony orchestra. The violin has been in existence since about 1550. Its importance as an instrument in its own right dates from the early 1600s, when it fist became standard in Italian opera orchestras. Its stature as an orchestral instrument was raised further when in 1626 Louis XIII of France established at his court the orchestra known as Les vinq-quatre violons du Roy (The King's 24 Violins), which was to become widely famous later in the century. In its early history, the violin had a dull and rather quiet tone resulting from the fact that the strings were thick and were attached to the body of the instrument very loosely. During the eighteenth and nineteenth century, exciting technical changes were inspired by such composer-violinists as Vivaldi and Tartini. Their instrumental compositions demanded a fuller, clearer, and more brilliant tone that was produced by using thinner strings and a far higher string tension. Small changes had to be made to the violin's internal structure and to the figerboard so that they could withstand the extra strain. Accordingly, a higher standard of performance was achieved, in terms of both facility and interpretation. Left-hand technique was considerably elaborated, and new tigering patterns on the figerboard were developed for very high notes.
