University researchers have taken samples from a preserved dodo specimen in an (46)         to uncover the extinct bird‟s family tree.

It was a flightless bird, bigger than a turkey. By 1681, all dodos had been (48)      by hungry sailors. The    solitaire, which looked a bit like a dodo, had gone the same way by 1800. By extracting short pieces of the dodo‟s DNA and (49)        these with the DNA of living birds, the scientists were able to deduce when the dodo evolved away from its relatives into a separate entity. The scientists can now (50)       assume that the dodo developed its distinctive appearance and features as a result of its geographical isolation. They are now convinced that it separated from the solitaire about 25 million years ago, long before Mauritius became an island.

   The countryside of Britain is well known for its beauty and many contrasts: its bare mountains and moorland, its lakes, rivers and woods, and its long, often wild coastline. Many of the most beautiful areas are national parks and are protected from development. When British people think of the countryside they think of farmland, as well as open spaces. They imagine cows or sheep in green fields enclosed by hedges or stone walls, and fields of wheat and barley. Most farmland is privately owned but is crossed by a network of public footpaths.

   Many people associate the countryside with peace and relaxation. They spend their free time walking or cycling there, or go to the country for a picnic or a pub lunch. In summer people go to fruit farms and pick strawberries and other fruit. Only a few people who live in the country work on farms. Many commute to work in towns. Many others dream of living in the country, where they believe they would have a better and healthier lifestyle.

   The countryside faces many threats. Some are associated with modern farming practices, and the use of chemicals harmful to plants and wildlife. Land is also needed for new houses. The green belt, an area of land around many cities, is under increasing pressure. Plans to build new roads are strongly opposed by organizations trying to protect the countryside. Protesters set up camps to prevent, or at least delay, the building work.

   America has many areas of wild and beautiful scenery, and there are many areas, especially in the West in states like Montana and Wyoming, where few people live. In the New England states, such as Vermont and New Hampshire, it is common to see small farms surrounded by hills and green areas. In Ohio, Indiana, Illinois and other Midwestern states, fields of corn or wheat reach to the horizon and there are many miles between towns.

   Only about 20% of Americans live outside cities and towns. Life may be difficult for people who live in the country. Services like hospitals and schools may be further away and going shopping can mean driving long distances. Some people even have to drive from their homes to the main road where their mail is left in a box. In spite of the disadvantages, many people who live in the country say that they like the safe, clean, attractive environment. But their children often move to a town or city as soon as they can.

   As in Britain, Americans like to go out to the country at weekends. Some people go on camping or fishing trips, others go hiking in national parks.

We can see from the passage that in the countryside of Britain ______.

In “Cerealizing America”, Scott Bruce and Bill Crawford remark that the cereal  industry uses 816 million pounds of sugar per year. Americans buy 2.7 billion  packages of breakfast cereal each year. If (1) _______ end to end, the empty  cereal boxes from one year's consumption would (2) _______ to the moon and back. One point three (1.3) million advertisements for cereal are broadcast on  American television every year at a(n) (3) _______ of $762 million for airtime.  Only automobile manufacturers spend more money on television advertising  than the makers of breakfast cereal. (4) _______ of the boxed cereals found in  supermarkets contain large amounts of sugar and some contain more than 50%  sugar. Cereal manufacturers are very clever in their marketing, making many  cereals appear much healthier than they really are by “fortifying” them with vitamins and minerals. Oh, (5) ______ – you now have vitamin-fortified sugar! Before you eat any cereal, read the ingredient list and see how (6) _______  sugar appears on the ingredient list. Then check the “Nutrition facts” panel. 
There are actually only a small handful of national commercially-branded cereals  that are made (7) _______ whole grains and are sugar-free. If you shop at a health  food store instead of your local supermarket, you (8) _______ to find a healthy,  whole grain, sugar-free (or very low sugar) cereal. But (9) _______! Some of the  health food store boxed cereals are sweetened with fruit juice or fructose.  Although this may be an improvement (10) _______ refined white sugar, this can  really skyrocket the calories.

Many of the most damaging and life-threaling types of weather-torrential rains, severe thunderstorms, and tornadoes-begin quickly, strike suddenly, and dissipate rapidly, devastating small regions while leaving neighboring areas untouched. One such event, a tornado, struck the northeastern section of Edmonton, Alberta, in July 1987. Total damages from the tornado exceeded $250 million, the highest ever for any Canadian storm. Conventional computer models of the atmosphere have limited value in predicting short-live local storms like the Edmonton tornado, because the available weather data are generally not detailed enough to allow computers to discern the subtle atmospheric changes that precede these storms. In most nations, for example, weather balloon observations are taken just once every twelve hours at locations typically separated by hundreds of miles. With such limited data, conventional forecasting models do a much better job predicting general weather conditions over large regions than they do forecasting specific local events.
Until recently, the observation-intensive approach needed for accurate, very short range forecasts, or “Nowcasts”, was not feasible. The cost of equipping and operating many thousands of conventional weather stations was prohibitively high, and the difficulties involved in rapidly collecting and processing the raw weather data from such a network were insurmountable. Fortunately, scientific and technological advances have overcome most of these problems. Radar systems, automated weather instruments, and satellites are all capable of making detailed, nearly continuous observation over large regions at a relatively low cost. Communications satellites can transmit data around the world cheaply and instantaneously, and modern computers can quickly compile and analyzing this large volume of weather information. Meteorologists and computer scientists now work together to design computer programs and video equipment capable of transforming raw weather data into words, symbols, and vivid graphic displays that forecasters can interpret easily and quickly. As meteorologists have begun using these new technologies in weather forecasting offices, Nowcasting is becoming a reality.

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.

When I saw her name on the screen, it took me right back to the moment she had moved away with her family ten years before. We had been such close friends at primary school. To begin with, she and I had not hit it off, perhaps because we were both timid. We had quickly got over that, though, and as time went on, we had become really good friends, until you almost never saw one of us without the other.

And now after so much time apart, there was her name. She had sent me a friend request. I knew she had been living abroad, and her profile picture showed her on the beach. I had been expecting her to look different after ten years. The girl in the photo was the same old Lauren, though.

Nowadays, it is easy to find old friends thanks to social networking sites. There are lots of stories about long lost friends getting back in touch after years apart. It was odd because I had been thinking about our friendship too and now here she was!

She told me about the place where she had been living for the past ten years, and I told her about things that had happened to me. Before long, the years melted away and we were the same two girls who had spent so much time together. Of course, true friends are loyal and listen to you when you are down. And they are the people you have fun with. But deep down, I realised that the truest friends are those you are most yourself with. And that is something that never changes. That is what Lauren and I learned that day, the day we realised our friendship was so precious and had never really ended in the first place.

The phrase “hit it off” in paragraph 1 mostly means _______.

Read the passage carefully, then choose the correct answer. 
A higher reading rate, with no loss of comprehension, will help you in other subjects as well as in English, and, the general principles apply to any language. Naturally, you will not read every book at the same speed. You would expect to read a newspaper, for example, much. more rapidly than physics or economics textbook — but you tan raise your average reading speed over the whole range of materials you wish to cover so that the percentage gained will be the same whatever kind of reading you are concerned with. 
The reading passages which follow are all of an average level of difficulty for your stage of instruction. They are all about five hundred words long. They are about topics of general interest which do not require a great deal of specialized knowledge. Thus they fall between the kind of reading you might find in your textbooks and the much less demanding kind you will find in a newspaper or light novel. If you read this kind of English, with understanding at four hundred words per minute, you might skim through a newspaper at perhaps 650 - 700 words per minute while with a difficult textbook you might drop to two hundred or two hundred and fifty. Perhaps you would like to know what reading speeds is common among native English-speaking university students and how those speeds can be improved. Tests in Minnesota, USA, for example, have shown that students without special training can read English of average difficulty, for example, Tolstoy's War and Peace in translation, at speed of between 240 and 250 words per minute with about seventy percent comprehension. Students in Minnesota claim that after twelve-half-hour lessons, once a week, the reading speed can be increased, with no loss of comprehension, to around five hundred words per minute.

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.

I’m standing on a sidewalk in the early morning. The great avenues of Paris are silent, and the shops are closed. Suddenly, a couple appeared from a hole in the sidewalk. Mud covers their boots. They place the iron cover over the hole and run down the street, smiling. The couple had been exploring the tunnels beneath the city.

When Romans occupied Paris, they cut down stone from deep within the earth to build their city. Later, the French used more stone to construct the Notre Dame Cathedral. This left huge underground tunnels upon which part of the city now. Once used for growing mushrooms and as a hiding place, today they are mostly forgotten, except by "cataphiles" - those who love to go down into the tunnels below Paris, even though it is actually not permitted.

In the 70s and 80s, it is easier to enter the tunnels because there were many more open entrances through forgotten doorways and into catacombs - rooms filled with bones. The bones had been moved into the tunnels to solve the problem crowded cemeteries. By the end of the 1980s, most of the entrances were shut and police regularly walked the tunnels. However, there are still cataphiles, like the couple I saw that morning, and for those who dare, the underground is an exciting place to meet, party, perform for each other or create art.

My own experience began beneath the old Paris opera house, where sewer workers showed me a 55-meter-long underground pond, a pond that actually had fish in it! Later, at France's national bank, officials guided me below to an amazing room filled with 2,600 tons of gold.

As cataphiles are the best guides, I then asked one of the cataphiles to give me a tour. Descending into the underground through a secret entrance beneath a bridge, we walked for hours through catacombs, and galleries of huge, bright paintings. The cataphile told me "Many people come down here to party, some to paint. Some people to destroy or to create or to explore. We do what we want, We don't have rules..."

If you want to prepare yourself for great achievement and have more to contribute to your education or your work, try reading more books. Pick up some of the interestingly informative books and search for well-researched material that can help you grow. 
We should encourage our children to read more books and spend less time watching TV. Some people have commented that this is inconsistent. "Why is the written word a superior way to get information than television?" That is an interesting point of view worth further exploration. Reading is a skill that is in much greater demand than the demand for watching TV. There are no jobs that require a person to be able to watch TV but reading is an integral part of many jobs. The written word is an incredibly flexible and efficient way of communication. You can write something down and, in no time, it can be sent to many different people. Not only that, we can digest vast amounts of information through reading in a very short time. A good reader can acquire more information in reading for two hours than someone watching TV can acquire in a full day. You are able to gain a lot of information quickly because you are a fast reader with good comprehension skills. It will save you massive amounts of time and you will be able to assimilate vast quantities of information.

   One day in 1924, five men who were camping in the Cascade Mountains of Washington saw a group of huge apelike creatures coming out of the woods. They hurried back to their cabin and locked themselves inside. While they were in, the creatures attacked them by throwing rocks against the walls of the cabin.

   After several hours, these strange hairy giants went back into the woods. After this incident the men returned to the town and told the people of their adventure. However, only a few people accepted their story. These were the people who remembered hearing tales about footprints of an animal that walked like a human being.

   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.

   Later many other people also found deep footprints in the same area. In spite of regular reports of sightings and footprints, most experts still do not believe that Bigfoot really exists.

   Telecommuting is a form of computer communication between employees’ homes and offices. For employees whose jobs involve sitting at a terminal or word processor entering data or typing reports, the location of the computer is of no consequence. If the machine can communicate over telephone lines, when the work is completed, employees can dial the office computer and transmit the material to their employers. A recent survey in USA Today estimates that there are approximately 8,7 million telecommuters. But although the numbers are rising annually, the trend does not appear to be as significant as predicted when Business Week published “The Portable

   Executive” as its cover story a few years ago. Why hasn’t telecommuting become more popular ?

   Clearly, change simply takes time. But in addition, there has been active resistance on the part of many managers. These executives claim that supervising the telecommuters in a large work force scattered across the country would be too difficult, or, at least, systems for managing them are not yet developed, thereby complicating the manager’s responsibilities.

   It is also true that employees who are given the option of telecommuting are reluctant to accept the opportunity. Most people feel that they need regular interaction with a group, and many are concerned that they will not have the same consideration for advancement if they are not more visible in the office setting. Some people feel that even when a space in their homes is set aside as a work area, they never really get away from the office.

The phrase “of no consequence” means ___________.

Poles Apart
Many are surprised to learn that Antarctica is nearly twice the size of the United States. The name Antarctica was coined to mean "opposite to the Arctic." It is just that in many ways. Antarctica is a high, ice-covered landmass. In the Arctic the landmasses are grouped around the ice-covered Arctic Ocean.
Largely because of this difference, the climate of the two areas is very different. Antarctica is the coldest area in the world. On the average it is about 30 degrees colder than the Arctic. At the South Pole, nearly 10.000 feet high, monthly mean temperatures run well below zero. Only in coastal regions do temperatures sometimes rise about freezing in the summer (December to March). In contrast, near the North Pole monthly mean temperatures often rise above freezing. 
At both poles, daily temperatures may drop far below the monthly mean. At the American South Pole Station, winter temperatures sometimes fall below -100 degrees Fahrenheit. Elsewhere, on higher parts of the south polar plateau, even lower temperatures are recorded.
A temperature of -127 degrees Fahrenheit was measured in August 1960. It is the world's record low temperature.
Partly because of this climatic difference, the land animals and plants of the two regions are very different. On the continent of Antarctica, there are very few plants. In the Arctic there are many plants. In some of the few ice-free areas of Antarctica, mosses, lichens, and algae are found. Penguins populate Antarctic coastlines but do not exist in the Arctic. The land animals of the Arctic are foxes, bears, reindeer, and lemmings. These animals are unknown in the Antarctic. Old rock layers show that this "oppositeness" between north and south extends far back into the early chapters of earth history.
Ice is the great feature of Antarctica. More than 4.5 million square miles of ice sheet cover the area. Great rivers of ice, called glaciers, push down the mountains. Antarctica is the storehouse of about 85 percent of the total world supply of ice. 
The icecap is very thick, averaging nearly 8,000 feet. At one spot, scientists have found the distance from the surface to the rock underneath the ice to be more than 13,000 feet.
If this great volume of ice were to melt, the volume of the world oceans would increase, and sea level would rise. Extreme atmospheric changes would have to take place for this to happen.
