Mystery of TimeIf you can read a clock, you will know the time of day. But no one knows what time itself is. We cannot see it. We cannot touch it. Nor can we hear it. We know it only by the way we mark its passing. For all our success in measuring the tiniest parts of time, time remains one of the great mysteries.One way of thinking about time is to imagine a world without time. There would be no movement, as time and movement cannot be separated. A world without time could exist only as long as there were no changes. For time and change are linked. When something changes, you know time has passed. In the real world, changes never stop. Some changes happen only once in a while, like an eclipse of the moon (月蚀). Others happen repeatedly, like the rising and setting of the sun. People have always noted natural events that repeat themselves. When people began to count such events, they began to measure time.In early human history, the only changes that seemed to repeat themselves evenly were the movements of objects in the sky. The most easily seen result of these movements was the difference between light and darkness.The sun rose in the eastern sky, producing light. It moved over peoples heads and sank in the western sky, causing darkness. The appearance and disappearance of the sun was even and unfailing. The periods of light and darkness it created were the first accepted periods of time. We have named each period light and darkness of one day. People saw the sun rise higher in the sky during the summer than in winter. They counted the days that passed from the suns highest position until it returned to that position. They counted 365 days. We now know that is the time Earth takes to move once around the sun. We call this period of time a year. Early humans also noted changes in the moon. As it moved across the night sky, they must have wondered: Why did it look different every night? Why did it disappear? Where did it go?Even before they learned the answers to these questions, they developed a way to use the moons changing faces to tell time. The moon was full when its face was bright and round. They counted the number of times the sun appeared between full moons. They learned that this number always remained the same, about 29 suns. Twenty-nine suns equaled one moon. We now know this period of time as one month.Early people killed animals and gathered wild plants. They moved in groups from place to place in search of food. Then people learned to plant seeds and grow crops. They learned to raise animals. They found they no longer needed to move from one place to another to survive. As hunters, people did not need a way to measure time. As farmers, however, they had to plant crops in time to harvest them before winter. They had to know when the seasons would change. So they developed calendars.No one knows when the first calendar was developed. But it seems possible that it was based on the movement of the moon, or lunar (阴历的) months. When people started farming, the wise men of the groups became very important. They studied the sky. They gathered enough information to be able to say when the seasons would change. They announced proper time to plant crops.The measurement of time we use today was developed in ancient Babylonia 4,000 years ago. Babylonians believed the sun moved around the Earth every 365 days. They divided the trip into 12 equal parts, or months. Each month was 30 days. Then they divided each day into 24 equal parts, or hours. They divided each hour into 60 minutes, and each minute into 60 seconds.Humans have used many devices to measure time. The sundial (日晷) was one of the earliest and simplest among all these devices. A sundial measures the movement of the sun across the sky each day. It has a stick or other object that rises above a flat surface. The stick, blocking light from the sun, creates a shadow. As the sun moves, so does the shadow of the stick across the flat surface. Marks on the surface show the passing of hours and perhaps minutes.The sundial worked well only when the sun was shining. So other ways of measuring the passing of time were invented. One device was the hourglass. It used a thin stream of falling sand to measure time. The hourglass was shaped like the number eight: wide at the top and bottom but very thin in the middle. Then you turned the hourglass upside down. And it began to mark the passing of another hour.By the 1700s, people had developed clocks and watches with machine parts. And today, many of our clocks and watches are electronic.So we have devices to mark the passing of time. But what time is it now? Clocks in different parts of the world do not show the same time at the same time. This is because time on Earth is set by the suns position in the sky above us. We all have a 12 oclock noon each day. Noon is the time when the sun is highest in the sky. But when it is 12 oclock noon where I am, it may be 10 oclock at night where you are.As international communications and travel grew, it became clear we needed a way to establish a common time for all parts of the world.In 1884, an international conference divided the world into 24 time areas, or zones. Each zone represents one hour. Greenwich, England, was chosen as the starting point for the time zones. Twelve zones are west of Greenwich. Twelve are east. The time at Greenwich as measured by the sun is considered to be Universal Time. We also know it as Greenwich Mean Time.Some scientists say time is governed by the movement of matter. They say time flows forward because everything is expanding. Some say it will stop expanding some day and will begin to move in the opposite direction, to grow smaller. Some believe time will also begin to flow in the opposite direction, from the future to the past.Some scientists believe there is one reason why time only moves forward. It is a well-known scientific law: the second law of thermodynamics (热力学). That law says disorder increases with time. In fact, there are more conditions of disorder than of order. For example, there are many ways a glass can break into pieces. Disorder. But there is only one way the broken pieces can be organized to make a glass. Order. If time moved backward, the broken pieces could come together in a great many ways. Only one of these many ways, however, would re-form the glass. It is almost impossible to believe this would happen.Not all scientists believe time is governed by the second law of thermodynamics. They do not agree that time must always move forward. As long as they debate the nature of time, time will remain a mystery. 1. When people began counting the movement of natural events, they began to measure time. A. Y B. N C. NG 2.

You may not use any of the words more than once. Questions 1 to 10 are based on the following passage. How does a scientist go about cloning a sheep? First they acquire an egg cell of a sheep. Then they combine it with the nucleus of a cell containing the DNA of the sheep they are attempting to clone. This is the ribbon-like molecule that contains 1. pursuemultiplyproceedexpandprocessgeneratedexertbanningclaimintactmountinnocentaccelerategeneticregulate information. This molecule comes from the nucleus of any living cell, but it must be 2. pursuemultiplyproceedexpandprocessgeneratedexertbanningclaimintactmountinnocentaccelerategeneticregulate if you want to clone an animal.

Almost all scientists believe it would, and this is the issue that has 5. pursuemultiplyproceedexpandprocessgeneratedexertbanningclaimintactmountinnocentaccelerategeneticregulate so much debate. The creation of Dolly has caused many organizations to 6. pursuemultiplyproceedexpandprocessgeneratedexertbanningclaimintactmountinnocentaccelerategeneticregulate energetic protests.

There, many government leaders are arguing over legislation that would 7. pursuemultiplyproceedexpandprocessgeneratedexertbanningclaimintactmountinnocentaccelerategeneticregulate cloning of humans. They fear that the implications of cloning are too enormous to be fully understood at this time. Many are advising 8. pursuemultiplyproceedexpandprocessgeneratedexertbanningclaimintactmountinnocentaccelerategeneticregulate experiments on cloning altogether until we know more about the scientific and moral dilemmas we might face.

If artists fail to recreate their image over and over againthey risk facing criticisms of dullness; that they are not fashionable.This phenomenon applies especially to the female ranks. It is not enough for an artist to be beautiful and sexy. These characteristics too must be changed often, and remodeled to avoid being bogged down by a stereotype.One example of the rock n roll
