Why is it that flying to New York from London will leave you feeling less tired than flying to London from New York? The answer may be a clear case of biology not being able to keep up with technology. Deep inside the brain there is a "clock" that governs every aspect of the body's functioning: sleep and wake cycles, levels of alertness, performance, mood, hormone levels, digestion, body temperature and so on. It regulates all of these functions on a 24-hour basis and is called the circadian clock (from the Latin, circa "about" + dies "day").

This body clock programmes us to be sleepy twice a day, between 3-5 a.m and again between 3-5 p.m. Afternoon tea and siesta times are all cultural responses to our natural biological sleepiness in the afternoon. One of the major causes of the travelers' malady known as jet lag is the non-alignment of a person's internal body clock with clocks in the external world. Crossing different time zones confuses the circadian clock, which then has to adjust to the new time and patterns of light and activity. To make matters more complex, not all internal body functions adjust at the same rate. So your sleep/wake may adjust to a new time zone at one rate, while your temperature adjusts at a different pace. Your digestion may be on a different schedule altogether.

Though we live in a 24-hour day, the natural tendency of the body clock is to extend our day beyond 24 hours. It is contrary to our biological programming to shrink our day. That is why travelling in a westward direction is more body-clock friendly than flying east. NASA studies of long haul pilots showed that westward travel was associated with significantly better sleep quantity and quality than eastward flights. When flying west, you are "extending" your day, thus travelling in the natural direction of your internal clock. Flying eastward will involve "shrinking" or reducing your day and is in direct opposition to your internal clock's natural tendency.

One of the more common complaints of travelers is that their sleep becomes disrupted. There are many reasons for this: Changing time zones and schedules, changing light and activity levels, trying to sleep when your body clock is programmed to be awake, disruption of the internal circadian clock and working longer hours. Sleep loss, jet lag and fatigue can seriously affect our ability to function well. Judgment and decision-making can be reduced by 50%, attention by 75 percent, memory by 20 percent and communication by 30 percent. It is often suggested that you adjust your watch as soon as you board a plane, supposedly to try to help you adjust to your destination's schedule as soon as you arrive. But it can take the body clock several days to several weeks to fully adjust to a new time zone.

Explosions in the Sky
If you attend a major outdoor event in the evening, whether it is in Paris, Beijing, or New York City, there is a good chance that it will end in a sensational way. After all of the other activities have concluded, the sky will be lit up by a colourful firework display. Although the show may only last for a few minutes, during that time every eye will look on with amazement as they work their magic in the air. Fireworks were invented in the seventh century by the Chinese. They were quickly absorbed into the culture and became a part of many celebratory events and festivals. Eventually, emperors would organize large firework displays to entertain and impress their subjects. Fireworks didn’t become big in Europe until the mid-17th century. People became interested in fireworks after reading accounts from monks and travellers who saw them while in China. Once they did arrive, it was obvious they were there to stay. Fireworks were frequently paired with triumphant classical symphonies to celebrate the end of wars and other great victories. As time went on, the fireworks continued to evolve and get better in many ways. Fireworks now come in every colour imaginable. The colour comes from different chemicals that are placed inside of each firework. Thanks to modern technology, it is also possible to create firework arrangements in the shape of hearts, smiley faces, and even the planet Saturn. This is because of the way that the aerial shells, or casings, of fireworks are constructed. The cases are packed with exploding pellets and a piece of cardboard. The cardboard enables the designers to arrange the pellets in pattern or shape of the object of their choice. The first time this technology was used was in Washington DC, during a celebration to welcome home American troops who fought in the Gulf War. The visual aspect is only part of the reason fireworks are appealing. The sounds that fireworks make also add a healthy dose of excitement to the display. There are several noises that fireworks can make. The most common is the “bang” which sounds a lot like a gunshot. Fireworks can also crackle, hum, and whistle as they streak across the night sky. The world’s largest firework show was held in Kuwait in 2012. 77,282 fireworks exploded during the incredible 64-minute show. But with people’s love for fireworks at an all-time high, who knows how long that record will last?

Read the following passage and choose the best answer (A, B, C, D):
Some technological developments are the results of years of diligent work. Others are stumbled upon by accident. The discovery of X-rays is in the second category. In 1895, X-ray radiation was accidentally discovered by a physicist named Wilhelm Rontgen, while he was working in his lab. Rontgen discovery greatly advanced medical science. One night in 1895, Wilhelm Rontgen was working with an electric device called a Crookes tube. A Crookes tube is a glass tube with metal components inside it. When turned on, the tube produces a stream of electrons. Rontgen and other scientists observed a new form of energy escaping from the front end of the Crookes tube. Rontgen wanted to be the first to discover this new mysterious energy. To do this, he needed to make sure the tube was covered with black cardboard. This would make the room completely dark and allow him to better see this new form of energy. Rontgen was hoping to observe this new energy on a special screen that would be placed right in front of the Crookes tube. Amazingly, before the screen was placed near the Crookes tube, Rontgen already noticed the screen was glowing. He bought the screen closer, and the glow became brighter. (1) He then placed a book between the end of the tube and the screen-the glow was still there. (2) Rontgen realized that a new and different form of radiation must be causing the screen to glow. (3) As he didn't know what kind of radiation it was, he named it "X". (4) Rontgen soon started studying the new type of radiation. He designed experiments which allowed him to test how far X- rays could penetrate. He also had the bright idea of trying to take photographs with X-rays. One day, he tested his theories by asking his wife to put her hand between a photographic plate and a Crookes Tube. Sure enough, the resulting image of the bones in his wife's hand was the first ever X-ray photograph of the human body. After taking that first photograph, Rontgen understood how X-rays could benefit doctors and patients. He shared his discovery, and soon X-ray machines were appearing in hospitals. X-rays were very useful for medicine because they let doctors see a patient's bones. If a patient had a broken bone, it was made visible by the X-ray image. This let doctors know the right way to repair the fracture. Wilhelm Rontgen's accidental discovery has now been helping people for over one hundred years. Thanks to X-rays, broken bones can be repaired reliably and effectively. We should be grateful to Wilhelm Rontgen for making his discovery freely available and greatly advancing medical science. Because of this, we humans are able to live longer, healthier lives.

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:
Fish that live on the sea bottom benefit by being flat and hugging the contours. There are two very differcent types of flatfish and they have evolved in very separate ways. The skates ad rays, relatives of the rharks, have become flat in what might be called the obivious way. Their bodies have grown out sideways to form grat “wings”. They look as though they have been flattened but have remained symmetrical and “the right way up”. Conversely, fish such sas plaice, sole, and halibut have become flat in a different way. There are bony fish which have a marked tendency to be flattened in a vertical direction; they are much “taller” than they are wide. They use their whole, vertically flattened bodies as swimming surfaces, which undulat through the water as they move. Therefore, when their ancestors migrate to the seabed, they lay on one side than on their bellies. However, this raises the problem that one eye was always looking down into the sand and was effectively useless – In evolution this problem was soleved by the lower eye “moving” around the other side. We see this process off moving around enacted in the development of every young bony flatfish. It starts life swimming near the surface, and is symmetrical and vertically flattened, but then the skull starts to grow in a strange asymmetrical twisted fashion,, so that one eye, for instance the left, moves over the top of the head upwards, an old Picasso – like vision. Incidentally, some species of 20 flatfish settle on the right side, others on left, and others on either side.

It can be inferred from the passage that the early life of a flatfish is     .
