For centuries, time was measured by the position of the sun with the use of sundials. Noon was recognized when the sun was the highest in the sky, and cities would set their clock by this apparent solar time, even though some cities would often be on a slightly different time. Daylight Saving Time (DST), sometimes called summer time, was instituted to make better use of daylight. Thus, clocks are set forward one hour in the spring to move an hour of daylight from the morning to the evening and then set back one hour in the fall to return to normal daylight.

   Benjamin Franklin first conceived the idea of daylight saving during his tenure as an American delegate in Paris in 1984 and wrote about it extensively in his essay, "An Economical Project." It is said that Franklin awoke early one morning and was surprised to see the sunlight at such an hour. Always the economist, Franklin believed the practice of moving the time could save on the use of candlelight, as candles were expensive at the time.

   In England, builder William Willett (1857–1915) became a strong supporter for Daylight Saving Time upon noticing blinds of many houses were closed on an early sunny morning. Willet believed everyone, including himself, would appreciate longer hours of light in the evenings. In 1909, Sir Robert Pearce introduced a bill in the House of Commons to make it obligatory to adjust the clocks. A bill was drafted and introduced into Parliament several times but met with great opposition, mostly from farmers. Eventually, in 1925, it was decided that summer time should begin on the day following the third Saturday in April and close after the first Saturday in October.

Is There Really a Generation Gap?

According to the results of a survey in USA WEEKEND Magazine, there isn’t really a generation gap. The magazine’s “Teens & Parents” survey shows that today’s generation of young people generally get along well with their parents and appreciate the way they’re being raised. Most feel that their parents understand them, and they believe their parents consider family as the No. 1 priority in their lives. Although more than a third of teens have something in their rooms they would like to keep secret from their parents, it is usually nothing more harmful than a diary or a CD.

Such results may seem surprising in the context of the violent events that people hear about in the media. Maybe because of the things they hear, parents worry that their own kids might get out of control once they reach the teenage years. However, the facts in the survey should make us feel better. The survey shows us that today’s teens are loving and sensible. They are certainly happier than the angry people in the teenage stereotypes we all know about. True, some teenagers are very angry, and we need to recognize their needs, but the great majority of teens are not like that at all.

In contrast to some stereotypes, most teens believe they must be understanding about differences among individuals. Many of them volunteer for community service with disadvantaged people. When they talk about themselves, their friends and their families, they sound positive and proud. Generally, these are very nice kids.

Is this spirit of harmony a change from the past? Only a generation ago, parent-child relations were described as the “generation gap”. Yet even then, things were not so bad. Most kids in the 1960s and 1970s shared their parents’ basic values.

Perhaps, however, it is true that American families are growing closer at the beginning of this new millennium. Perhaps there is less to fight about, and the dangers of drug abuse and other unacceptable behavior are now well known. Perhaps, compared to the impersonal world outside the home, a young person’s family is like a friendly shelter, not a prison. And perhaps parents are acting more like parents than they did 20 or 30 years ago.

According to the first paragraph, what did the survey find out about teenagers?

 The mineral particles found in soil range in size from microscopic clay particles to large boulders. The most abundant particles - sand, silt, and clay - are the focus of examination in studies of soil texture. Texture is the term used to describe the line composite sizes of particles in a soil sample, typically several representative handfuls . To measure soil texture, the sand, silt, and clay particles are sorted out by size and weight. The weights of each size are then expressed as a percentage of the sample weight.

   In the field, soil texture can be estimated by extracting a handful of sod and squeezing the damp soil into three basic shapes; (1) cast, a lump formed by squeezing a sample in a clenched fist; (2) thread, a pencil shape formed by rolling soil between the palms; and (3) ribbon, a flatfish shape formed by squeezing a small sample between the thumb and index finger. The behavioral characteristics of the soil when molded into each of these shapes, if they can be formed at all, provides the basis for a general textural classification. The behavior of the soil in the hand test is determined by the amount of clay in the sample. Clay particles are highly cohesive, and when dampened , behave as a plastic. Therefore the higher the clay content in a sample, the more refined and durable the shapes into which it can be molded

 It can be inferred from the passage that a soil sample with little or no clay in it ______.

We get great pleasure from reading. The more advanced a man is, the greater delight he will find in reading. The ordinary man may think that subjects like philosophy or science are very difficult and that if philosophers and scientists read these subjects, it is not for pleasure. But this is not true. The mathematician finds the same pleasure in his mathematics as the school boy in an adventure story. For both, it is a play of the imagination, a mental recreation and exercise.

   The pleasure derived from this activity is common to all kinds of reading. But different types of books give us different types of pleasure. First in order of popularity is novel-reading. Novels contain pictures of imaginary people in imaginary situations, and give us an opportunity of escaping into a new world very much like our world and yet different from it. Here we seem to live a new life, and the experience of this new life gives us a thrill of pleasure.

The word “derived” in paragraph 2 is closest in meaning to ______

A birthday party is a celebration that occurs to celebrate the birth of the person being honored. Birthday parties are celebrated in many cultures. While a child’s party is usually at home and consists of soft drinks and sweet food as well as some main courses, adults’ birthday parties in Western countries often take place in bars or nightclubs where a range of alcoholic beverages are consumed. 

In Western cultures, particularly in the United States, birthday parties are often accompanied by colorful decorations such as streamers and balloons. A birthday cake is often served with candles that are to be blown out after a “birthday wish” has been made. While the birthday cake is brought to the table, the song Happy Birthday to You is sung. Wealthy people or celebrities may hire an event management agency or a party service to organize a birthday party. 

The birthday cake has been an integral part of the birthday tradition in Western cultures since the middle of the 19th century.

The cake, or sometimes a pastry or dessert, is served to a person on his or her birthday, and is often decorated with small novelty candles, with the person’s name and a message of congratulations inscribed with icing. The phrase “Happy Birthday” did not appear on birthday cakes until the song Happy Birthday to You was popularized in the early 1900s.

Tradition holds that the person with the birthday may make a wish, which will come true if all the candles can be blown out in one breath.

Children’s birthday parties are celebrated ____.

The White House, the official home of the United States president, was not built in time for George Washington to live in it. It was begun in 1792 and was ready for its first inhabitants. President and Mrs.John Adams, who moved in on November 1, 1800. When the Adamses moved in, the White House was not yet complete, and the Adamses suffered many inconveniences; for example, the main staircase was incomplete, which hindered movement from floor to floor, and the future laundry yard was merely a pool of mud, so wet laundry was hung in the unfinished East Room to dry. Thomas Jefferson, the third president, improved the comfort of the White House in many respects and added new architectural features such as the terraces on the east and west ends.

   When the British forces burned the White House on August 24, 1814, President Madison was forced to leave.All the remained after the fire was the exterior walls, the interior was completely destroyed. It was not until December of 1817 that the following president, James Monroe, was able to move into a rebuilt residence. Since then, the White House has continued to be modified but has been continuously occupied by each succeeding U.S president.

 It can be inferred from the passage that John Adams was:

In full computer animation, complex mathematical formulas are used to produce the final sequences of pictures. These formulas operate on extensive databases of numbers that defines the objects in the pictures as they exist in mathematical space. The database consists of endpoints, and color and intensity information. Highly trained professionals are needed to produce such effects because animation that obtains high degrees of realism involves computer techniques from three-dimensional transformation, shading, and curvatures.

   High-tech computer animation for film involves very expensive computer systems along with special color terminals or frame buffers. The frame buffer is nothing more than a giant image memory for viewing a single frame. It temporarily holds the image for display on the screen.

At the factory he likes people to let him have his own way

Herman Melville, an American author best known today for his novel Moby Dick, was actually more popular during his lifetime for some of his other works. He traveled extensively and used the knowledge gained during his travels as the basis for his early novels. In 1837, at the age of eighteen, Melville signed as a cabin boy on a merchant ship that was to sail from his Massachusetts home to Liverpool, England. His experiences on this trip served as a basis for the novel Redburn (1849). In 1841 Melville set out on a whaling ship headed for the South Seas. After jumping ship in Tahiti, he wandered around the islands of Tahiti and Moorea. This South Sea island sojourn was a backdrop to the novel Omoo (1847). After three years away from home, Melville joined up with a U.S. naval frigate that was returning to the eastern United States around Cape Horn. The novel White-Jacket (1850) describes this lengthy voyage as a navy seaman. With the publication of these early adventure novels, Melville developed a strong and loyal following among readers eager for his tales of exotic places and situations. However, in 1851, with the publication of Moby Dick, Melville's popularity started to diminish. Moby Dick, on one level the saga of the hunt for the great white whale, was also a heavily symbolic allegory of the heroic struggle of man against the universe. The public was not ready for Melville's literary metamorphosis from romantic adventure to philosophical symbolism. It is ironic that the novel that served to diminish Melville's popularity during his lifetime is the one for which he is best known today.

How did the publication of Moby Dick affect Melville’s popularity?

      ARE TRADITIONAL WAYS OF LEARNING THE BEST?

Read about some alternative schools of thought…

One school in Hampshire, UK, offers 24-hour teaching. The children can decide when or if they come to school. The school is open from 7 a.m. to 10 p.m., for 364 days a year and provides online teaching throughout the night. The idea is that pupils don't have to come to school and they can decide when they want to study. Cheryl Heron, the head teacher, said “Some students learn better at night. Some students learn better in the morning.” Cheryl believes that if children are bored, they will not come to school. “Why must teaching only be conducted in a classroom? You can teach a child without him ever coming to school.”

Steiner schools encourage creativity and free thinking so children can study art, music and gardening as well as science and history. They don’t have to learn to read and write at an early age. At some Steiner schools the teachers can’t use textbooks. They talk to the children, who learn by listening. Every morning the children have to go to special music and movement classes called “eurhythmy”, which help them learn to concentrate. Very young children learn foreign languages through music and song. Another difference from traditional schools is that at Steiner schools you don't have to do any tests or exams.

A child learning music with the Suzuki method has to start as young as possible. Even two-year-old children can learn to play difficult pieces of classical music, often on the violin. They do this by watching and listening. They learn by copying, just like they learn their mother tongue. The child has to join in, but doesn't have to get it right. “They soon learn that they mustn't stop every time they make a mistake. They just carry on,” said one Suzuki trainer. The children have to practise for hours every day and they give performances once a week, so they learn quickly. “The parents must be involved too,” said the trainer, “or it just doesn't work.”

   Hummingbirds are small, often brightly colored birds of the family Trochilidae that live exclusively in the Americas. About 12 species are found in North America, but only the ruby-throated hummingbird breeds in eastern North America and is found from Nova Scotia to Florida. The greatest variety and number of species are found in South America. Another hummingbird species is found from southeastern Alaska to northern California.

   Many hummingbirds are minute. But even the giant hummingbird found in western South America, which is the largest known hummingbird, is only about 8 inches long and weighs about two-thirds of an ounce. The smallest species, the bee hummingbird of Cuba and the Isle of Pines, measures slightly more than 5.5 centimeters and weighs about two grams.

   Hummingbirds' bodies are compact, with strong muscles. They have wings shaped like blades. Unlike the wings of other birds, hummingbird wings connect to the body only at the shoulder joint, which allows them to fly not only forward but also straight up and down, sideways, and backward. Because of their unusual wings hummingbirds can also hover in front of flowers so they can suck nectar and find insects. The humming- bird's bill, adapted for securing nectar from certain types of flowers, is usually rather long and always slender, and it is curved slightly downward in many species.

   The hummingbird’s body feathers are sparse and more like scales than feathers. The unique character of the feathers produces brilliant and iridescent colors, resulting from the refraction of light by the feathers. Pigmentation of other feathers also contributes to the unique color and look. Male and female hummingbirds look alike in some species but different in most species; males of most species are extremely colorful.

   The rate at which a hummingbird beats its wings does not vary, regardless of whether it is flying forward, flying in another direction, or merely hovering. But the rate does vary with the size of the bird - the larger the bird, the lower the rate, ranging from 80 beats per second for the smallest species to 10 times per second for larger species. Researchers have not yet been able to record the speed of the wings of the bee humming-bird but imagine that they beat even faster. Most hummingbirds, especially the smaller species, emit scratchy, twittering, or squeaky sounds. The wings, and sometimes the tail feathers, often produce humming, hissing, or popping sounds, which apparently function much as do the songs of other birds.

According to the passage, what causes the unique color and look of hummingbirds?

Read the following passage and choose the best answer.

Becoming independent

Many young people strive to be independent. That means you are able to take care of yourself, and you don't have to rely on anyone else. However, to live independently, you need a number of life skills in order not to depend on your parents and older brothers or sisters. One of the most important skills is time management which can help you build your confidence and self-esteem. With good time management skills, you can perform your daily tasks, including your responsibilities at school and at home with pleasing results. Moreover, you will not feel stressed when exam dates are approaching. These skills can also help you act more independently and responsibly, get better grades at school, and have more time for your family and friends.

Developing time-management skills is not as challenging as you may think. Firstly, make a plan for things you need to do, including appointments and deadlines. Using a diary or apps on mobile devices will remind you of what you need to accomplish and when you need to accomplish it. Secondly, prioritize your activities. You need to decide which tasks are the most urgent and important and then, concentrate on these first. This way, you may not be at a loss to deal with too much work at the same time. Thirdly, develop routines because routines, when established, take less time for you to do your tasks.

Time management skills are not hard to develop; once you master them, you will find out that they are great keys to success and you can become independent.

 In the 1960s, The Beatles were probably the most famous pop group in the whole world. Since then, there have been a great many groups that have achieved enormous fame, so it is perhaps difficult now to imagine how sensational The Beatles were at that time. They were four boys from the north of England and none of them had any training in music. They started by performing and recording songs by black Americans and they had some success with these songs. Then they started writing their own songs and that was when they became really popular. The Beatles changed pop music. They were the first pop group to achieve great success from songs they had written themselves. After that it became common for groups and singers to write their own songs. The Beatles did not have a long career.

As Christmas evolved in the United States, new customs were adopted and many old ones were reworked. The legend of Santa Claus, for example, had origins in Europe and was brought by Dutch settlers to New York in the early 18th century. Traditionally, Santa Claus - from the Dutch Sinter Klaas - was depicted as a tall, dignified, religious figure riding a white horse through the air. Known as Saint Nicholas in Germany, he was usually accompanied by Black Peter, an elf who punished disobedient children. In North America he eventually developed into a fat, jolly old gentleman who had neither the religious attributes of Saint Nicholas nor the strict disciplinarian character of Black Peter.

Santa's transformation began in 1823, when a New York newspaper published the poem " A Visit from Saint Nicholas ", which Clemen Clark Moore had written to amuse his daughter. The poem introduced many Amercians to the story of a kindly saint who flew over housestops in a reindeer-drawn sleigh. Portraits and drawings of Santa Claus by American illustrator Thomas Nast further strengthened the legend during the second half of the 19th century. Living at the North Pole and assisted by elves, the modern Santa produced and delivered toys to all good children. By the late 19th century, he had become such a prominent figure of American folklore that in 1897, when Virginia O'Hanlon wrote to the New York Sun newspaper asking if Santa was real, she received a direct answer : " Yes, Virginia, there is a Santa Claus ".

   A rather surprising geographical feature of Antarctica is that a huge freshwater lake, one of the world’s largest and deepest, lies hidden there under four kilometers of ice. Now known as Lake Vostok, this huge body of water is located under the ice block that comprises Antarctica. The lake is able to exist in its unfrozen state beneath this block of ice because its waters are warmed by geothermal heat from the earth’s core. The thick glacier above Lake Vostok actually insulates it from the frigid temperatures on the surface.

   The lake was first discovered in the 1970s while a research team was conducting an aerial survey of the area. Radio waves from the survey equipment penetrated the ice and revealed a body of water of indeterminate size. It was not until much more recently that data collected by satellite made scientists aware of the tremendous size of the lake; the satellite-borne radar detected an extremely flat region where the ice remains level because it is floating on the water of the lake.

   The discovery of such a huge freshwater lake trapped under Antarctica is of interest to the scientific community because of the potential that the lake contains ancient microbes that have survived for thousands of years, unaffected by factors such as nuclear fallout and elevated ultraviolet light that have affected organisms in more exposed areas. The downside of the discovery, however, lies in the difficulty of conducting research on the lake in such a harsh climate and in the problems associated with obtaining uncontaminated samples from the lake without actually exposing the lake to contamination. Scientists are looking for possible ways to accomplish this.

 What is true of Lake Vostok?

 The five men, however, were not the first people to have seen these creatures called Bigfoot. Long before their experience, local Native Americans were certain that a race of apelike animals had been living in the neighboring mountain for centuries. They called these creatures Sasquatch.

   In 1958, workmen, who were building a road through the jungles of Northern California often found huge footprints in the earth around their camp.

   Then in 1967, Roger Patterson, a man who was interested in finding Bigfoot went into the Northern California jungles with a friend. While riding, they were suddenly thrown off from their horses. Patterson saw a tall apelike animal standing not far away. He managed to shoot seven rolls of film of the hairy creature before the animal disappeared in the hushes. when Patterson's film was shown to the public, not many people believed his story.

   In another incident, Richard Brown, a music teacher and also an experienced hunter spotted a similar creature. He saw the animal clearly through the telescopic lens of his rifle. He said the creature looked more like a human than an animal.

What did the five campers do when they saw a group of apelike creatures?
