选修9 Unit 1 Breaking records-Reading"THE ROAD IS ALWAYS AHEAD OF YOU"Ashrita Furman is a sportsman who likes the challenge of breaking Guinness records. Over the last 25 years, he has broken approximately 93 Guinness records. More than twenty of these he still holds, including the record for having the most records. But these records are not made in any conventional sport like swimming or soccer. Rather Ashrita attempts to break records in very imaginative events and in very interesting places.Recently, Ashrita achieved his dream of breaking a record in all seven continents, including hula hooping in Australia, pogo stick jumping under water in South America, and performing deep knee bends in a hot air balloon in North America.While these activities might seem childish and cause laughter rather than respect, in reality they require an enormous amount of strength and fitness as well as determination.Think about the fine neck adjustments needed to keep a full bottle of milk on your head while you are walking. You can stop to rest or eat but the bottle has to stay on your head.While Ashrita makes standing on top of a 75 cm Swiss ball look easy, it is not. It takes a lot of concentration and a great sense of balance to stay on it. You have to struggle to stay on top especially when your legs start shaking.And what about somersaulting along a road for 12 miles? Somersaulting is a tough event as you have to overcome dizziness, extreme tiredness and pain. You are permitted to rest for only five minutes in every hour of rolling but you are allowed to stop briefly to vomit.Covering a mile in the fastest time while doing gymnastically correct lunges is yet another event in which Ashrita is outstanding. Lunges are extremely hard on your legs. You start by standing and then you step forward with the fight foot while touching the left knee to the ground. Then you stand up again and step forward with the left foot while touching the fight knee to the ground. Imagine doing this for a mile!Yet this talented sportsman is not a natural athlete. As a child he was very unfit and was not at all interested in sports. However, he was fascinated by the Guinness Book of World Records.How Ashrita came to be a sportsman is an interesting story. As a teenager, he began searching for a deeper meaning in life. He studied Eastern religions and, aged 16, discovered an Indian meditation teacher called Sri Chinmoy who lived in his neighbourhood in New York City. Since that time in the early 1970s, Ashrita has been one of Sri Chinmoy's students. Sri Chinmoy says that it is just as important for people to develop their bodies as it is to develop their minds, hearts and spiritual selves. He believes that there is no limit to people's physical abilities.When Ashrita came third in a 24-hour bicycle marathon in New York's Central Park in 1978, he knew that he would one day get into the Guinness Book of World Records. He had been urged by his spiritual leader to enter the marathon even though he had done no training. So, when he won third place, he came to the understanding that his body was just an instrument of the spirit and that he seemed to be able to use his spirit to accomplish anything. From then on, Ashrita refused to accept any physical limitation.With this new confidence, Asharita broke his first Guinness record with 27,000 jumping jacks in 1979. The motivation to keep trying to break records comes through his devotion to Sri Chinmoy. Every time Ashrita tries to break a record, he reaches a point where he feels he cannot physically do any more. At that moment, he goes deep within himself and connects with his soul and his teacher.Ashrita always acknowledges his teacher in his record-breaking attempts.In fact, he often wears a T-shirt with Sri Chinmoy's words on the back. The words are:"There is only one perfect road. It is ahead of you, always ahead of you."FOCUS ON ...Lance ArmstrongDate of Birth: 8th September, 1971Country: USALance Armstrong's Guinness record for the fastest average speed at the Tour de France was set in 1999 with an average speed of 40.27 km/hr. In his teens he was a triathlete but at 16 he began to concentrate on cycling. He was an amateur cyclist before the 1992 Olympic Games but turned professional after he had competed in the Games. In the following few years, he won numerous titles, and by 1996 he had become the world's number one. However, in October 1996, he discovered he had cancer and had to leave cycling. Successfully fighting his illness, Armstrong officially returned to racing in 1998. In 1999 he won the Tour de France and in 2003 he achieved his goal of winning five Tours de France.Michellie JonesDate of Birth: 9th June, 1969Country: AustraliaIn 1988 Michellie Jones helped establish the multi-sport event, the triathlon, in Australia. After completing her teaching qualifications in 1990, she concentrated on the triathlon. In 1991, she finished third at the world championships. In 1992 and 1993, she was the International Triathlon Union World Champion. Since then, she has never finished lower than fourth in any of the world championships she has competed in. At the Sydney Olympics in 2000 she won the silver medal in the Women's Triathlon, the first time the event had been included in the Olympic Games. Recently, for the first time in 15 years, Jones was not selected as part of the national team and therefore did not compete in the 2004 Olympics in Athens.Fu MingxiaDate of Birth: 16th August, 1978Country: ChinaFu Mingxia first stood on top of the 10-metre diving platform at the age of nine. At 12 years old she won a Guinness Record when she became the youngest female to win the women's world title for platform diving at the World Championships in Australia in 1991. At the 1992 Barcelona Olympic Games, she took the gold medal in the women's 10-metre platform, becoming the youngest Olympic diving champion of all time. This was followed by great success at the 1996 Atlanta Olympic Games where she won gold for both the 10-metre platform and the three-metre springboard. This made her the first woman in Olympic diving history to win three gold medals. She retired from diving after Atlanta and went to study economics at university. While there she decided to make a comeback and went on to compete at the Sydney Olympic Games, where she won her fourth Olympic gold, again making Olympic history.Martin StrelDate of Birth: 1st October, 1954Country: SloveniaStrel was trained as a guitarist before he became a professional marathon swimmer in 1978. He has a passion for swimming the world's great rivers. In 2000, he was the first person ever to swim the entire length of the Danube River in Europe - a distance of 3,004 kilometres in 58 days. For this, he attained his first entry in the Guinness Book of World Records. Then in 2001 he broke the Guinness record for non-stop swimming - 504.5 kilometres in the Danube River in 84 hours and 10 minutes. Martin won his third entry in the Guinness Book of World Records in 2002 when he beat his own record for long distance swimming by swimming the length of the Mississippi River in North America in 68 days, a total of 3,797 kilometres. Then in 2003 he became the first man to have swum the whole 1,929 kilometres of the difficult Parana River in South America.In 2004, Strel again broke his own Guinness record by swimming the length of the dangerous Changjiang River (4,600 km), the third longest fiver in the world.选修9 Unit 2 Sailing the oceans-ReadingSRILING THE OCERNSWe may well wonder how seamen explored the oceans before latitude and longitude made it possible to plot a ship's position on a map. The voyages of travellers before the 17th century show that they were not at the mercy of the sea even though they did not have modern navigational aids. So how did they navigate so well? Read these pages from an encyclopedia.Page 1:Using nature to help Keeping alongside the coastlineThis seems to have been the first and most useful form of exploration which carried the minimum amount of risk.Using celestial bodiesNorth StarAt the North Pole the North Star is at its highest position in the sky, but at the equator it is along the horizon. So accomplished navigators were able to use it to plot their positions.SunOn a clear day especially during the summer the sailors could use the sun overhead at midday to navigate by. They can use the height of the sun to work out their latitude.CloudsSea captains observed the clouds over islands. There is a special cloud formation which indicates there is land close by.Using wildlifeSeaweedSailors often saw seaweed in the sea and could tell by the colour and smell how long it had been them. If it was fresh and smelled strongly,then the ship was close to land.BirdsSea birds could be used to show the way to land when it was nowhere to be seen. In the evening nesting birds return to land and their nests. So seamen could follow the birds to land even if they were offshore and in the open sea.Using the weatherFogFog gathers at sea as well as over streams or rivers. Seamen used it to help identify the position of a stream or river when they were close to land.WindsWise seamen used the winds to direct their sailing. They could accelerate the speed, but they could also be dangerous. So the Vikings would observe the winds before and during their outward or return journeys.Using the seaCertain tides and currents could be used by skillful sailors to carry ships to their destination.These skills helped sailors explore the seas and discover new lands. They increased their ability to navigate new seas when they used instruments.Page 2:Using navigational instruments to helpFinding longitudeThere was no secure method of measuring longitude until the 17th century when the British solved this theoretical problem. Nobody knew that the earth moved westwards 15 degrees every hour, but sailors did know an approximate method of calculating longitude using speed and time. An early method of measuring speed involved throwing a knotted rope tied to a log over the side of the ship. The rope was tied to a log which was then thrown into the sea. As the ship advanced through the water the knots were counted as they passed through a seaman's hands. The number of knots that were counted during a fixed period of time gave the speed of the ship in nautical miles per hour.Later, when seamen began to use the compass in the 12th century they could calculate longitude using complicated mathematical tables. The compass has a special magnetic pointer which always indicates the North Pole, so it is used to help find the direction that the ship needs to go. In this way the ship could set a straight course even in the middle of the ocean.Finding latitudeThe Bearing CircleIt was the first instrument to measure the sun's position. A seaman would measure the sun's shadow and compare it with the height of the sun at midday. Then he could tell if he was sailing on his correct rather than a random course.A Bearing CircleThe AstrolabeThe astrolabe, quadrant and sextant are all connected. They are developments of one another. The earliest, the astrolabe, was a special all-in-one tool for telling the position of the ship in relation to the sun and various stars which covered the whole sky. This gave the seamen the local time and allowed them to find their latitude at sea. However, it was awkward to use as one of the points of reference was the moving ship itself.The QuadrantThis was a more precise and simplified version of the astrolabe. It measured how high stars were above the horizon using a quarter circle rather than the full circle of the astrolabe.It was easier to handle because it was more portable. Its shortcoming was that it still used the moving ship as one of the fixed points of reference. As the ship rose and plunged in the waves, it was extremely difficult to be accurate with any reading.The sextantThe sextant was the updated version of the astrolabe and quadrant which reduced the tendency to make mistakes. It proved to be the most accurate and reliable of these early navigational instruments. It works by measuring the angle between two fixed objects outside the ship using two mirrors. This made the calculations more precise and easier to do.THE GREATEST NA VIGATIONAL JOURNEY:A LESSON IN SURVIV ALI am proud to have sailed with Captain Bligh on his journey of over 40 days through about 4,000miles in an open boat across the Pacific Ocean in 1789. Our outward voyage in the "Bounty" to Tahiti had been filled with the kind of incidents that I thought would be my stories when I returned home. But how wrong I was! On our departure from Tahiti, some of the crew took over the ship.They deposited the captain into a small boat to let him find his own way home. But who else was to go with him? Those of us on board the "Bounty" were caught in a dilemma. Was it better to risk certain death by sitting close together on a small, crowded open boat with very little food and water? Or should one stay on the "Bounty" with the crew and face certain death from the British Navy if caught? The drawback of staying on the ship seemed to grow as I thought about how wrong it was to treat Captain Bligh in this way. So I joined him in the small boat. As dusk fell, we seemed to face an uncertain future. We had no charts and the only instruments the captain was allowed to take with him were a compass and a quadrant.Once we were at sea, our routine every day was the same. At sunrise and sunset the captain measured our position using the quadrant and set the course using the compass. It was extremely difficult for us to get a correct reading from the quadrant as the boat moved constantly. The captain used a system called "dead reckoning". He knew there was land directly northwest of our original position. So his task was to make sure we stayed on that course. As you can see from the map wekept to a straight course pretty well. In addition, the captain kept us all busy reading the tables to work out our position. Although this took a great deal of time, it didn't matter. Time was, after all, what we had a lot of!Our daily food was shared equally among us all: one piece of bread and one cup of water. It was starvation quantities but the extreme lack of water was the hardest to cope with psychologically. Imagine all that water around you, but none of it was safe to drink because the salt in it would drive you mad! All the time the captain tried to preserve our good spirits by telling stories and talking hopefully about what we would do when we got back to England. We only half believed him.The tension in the boat got worse as the supply of food and water gradually disappeared. We could foresee that we would die if we could not reach land very soon and we sank gradually into a sleepy, half-alive state. The captain was as weak as the rest of us, but he was determined not to give up. He continued his navigational measurements every day. He kept us busy and tried to take our minds off our stomachs and our thirst. He kept us alive.You could not imagine a more disturbing sight than what we looked like when arriving in Timor over forty days after being set loose in our small boat. Our clothes were torn, we had fever and our faces showed the hardships we had suffered. But after a rest, some good meals and some new clothes, everything changed. We couldn't stop talking about our voyage and everybody wanted to hear about it. We were the heroes who had escaped the jaws of death by completing the greatest navigational feat of all time!选修9 Unit 3 Australia-ReadingGLIMPSES OF AUSTRALIAAUSTRALIACapital: Canberra Offcial name: Commonwealth of AustraliaArea: 7,686,850 km2 Population: 20 millionHighest point: Mount Kosciuszko, 2,228 metres above sea levelLowest point: Lake Eyre, 15 metres below sea levelAustralia is the only country that is also a continent. It is the sixth largest country in the world and is in the smallest continent - Oceania. It is a mainly dry country with only a few coastal areas that have adequate rainfall to support a large population. Approximately 80 of Australians live in the south-eastern coastal area, which includes Australia's two largest cities – Melbourne and Sydney. The centre of the continent, which is mainly desert and dry grassland, has few settlements.Australia is famous for its huge, open spaces, bright sunshine, enormous number of sheep and cattle and its unusual wildlife, which include kangaroos and koalas. Australia is a popular destination with tourists from all over the world who come to experience its unique ecology.Australia is made up of six states. Like the states in America, Australian states are autonomous in some areas of government. However, Australia has a federal government responsible for matters that affect people all over the country, such as defence, foreign policy and taxation. The federal parliament is located in Canberra.CITIZENSHIP CEREMONIES PLANNED AROUND AUSTRALIAOn 26 January, Australia Day, in over 200 locations across the nation , more than 9,000 people will become Australian citizens."By these citizenship ceremonies we welcome those who have come from overseas from many different cultural and social backgrounds into our communities and our nation," said the Minister for Citizenship and Multicultural Affairs. "Australia Day celebrations that include people from so many birthplaces are an excellent way to encourage tolerance, respect and friendship among all the people of Australia."Most citizenship ceremonies will be followed by displays of singing and dancing from manyof the migrants' homelands and the tasting of food from all over the world.Go by plane and see cloudsGo by TRAIN and see AustraliaEnjoy 3 nights on board the Indian-PacificOn this 4,352-km journey from Sydney to Perth via Adelaide you'll view some ot Australias unique scenery from the superb Blue Mountains to the treeless plains of the Nuliarbor.

There are also a range of short walks.Reading and discussingBefore you read the following text, read the title and look at the pictures. Discuss with a partner what you expect to read about in the text.AUSTRALIA’S DANGEROUS CREATURESAustralia is home to more than 170 different kinds of snake and 115 of these are poisonous. In fact, Australia has more kinds of venomous snake than any other country in the world. Luckily, the poison of most snakes can kill or paralyze only small creatures.A few varieties, however, can kill humans, so it is just as well that snakes are very shy and usually attack only if they are disturbed and feel threatened.There are also approximately 2,000 different kinds of spider in Australia and, like snakes, most have a poisonous bite. However, the majority have no effect on humans or cause only mild sickness.Only a few have venom that is powerful enough to kill a human being. While a small number of Australians are bitten by spiders each year, most recover without any medical treatment.The seas around Australia contain over 160 different kinds of shark, which vary in size fromjust 20 centimetres to over 14 metres. However, although they look dangerous because of their wide mouths and sharp teeth, all but two or three kinds are harmless to humans.Another potentially dangerous sea animal is the jellyfish. Most kinds of poisonous jellyfish can cause severe pain to anyone who touches them but the poison of the box jellyfish can actually kill a human, especially if that person has a weak heart. The tiniest amount of poison from a box jellyfish can kill in less than five minutes and it is probably the most poisonous animal in the world.There is one other dangerous animal in Australia worth mentioning, and that is the crocodile. Although two types of crocodile live in Australia, only the saltwater crocodile has been known to kill humans. This crocodile moves very quickly when it sees something it considers to be food, and from time to time a crocodile has snatched someone before he or she is even aware that the crocodile is there.You might think that with all these dangerous animals Australia is an unsafe place to live in or visit. However, this is far from the truth. There are no more than a handful of shark attacks each year and only three deaths have been reported in the last five years.Similarly, in the last three years there have been only two reported deaths from crocodile attacks. Since 1956, when an anti-venom treatment for redback spider bites was developed, there have been no deaths from redbacks, and since 1981 when a treatment was developed for funnelweb spider poison, there have been no deaths from this spider either. Treatments for jellyfish stings and s~aakebites have also been developed and in the last five years there have been only three deaths from jellyfish stings and about the same number from snakebites.选修9 Unit 4 Exploring plants-ReadingPLANT EXPLORATION IN THE 18TH AND 19TH CENTURIESThe plants in our gardens look so familiar that often we do not realize that many of them actually come from countries far away. Collecting "exotic" plants, as they are called, dates back to the earliest times. Many ancient civilisations saw the value of bringing back plants from distant lands. The first plant collecting expedition recorded in history was around 1500 BC when the Queen of Egypt sent ships away to gather plants, animals and other goods.However, it was not until the eighteenth and nineteenth centuries that the exploration of the botanical world began on a large scale. Europe had become interested in scientific discovery and the European middle classes took great interest in collecting new plants. Thisattraction to exotic plants grew as European nations, like the Netherlands, Britain and Spain, moved into other parts of the world like Asia and Australia. Brave young men took the opportunity of going on botanical expeditions, often facing many dangers including disease,near-starvation, severe environments and conflicts with the local people.An important group of collectors were Frencn Catholic missionaries who, by the middle of the 18th century, were beginning to set themselves up in China. One such missionary, Father d'Incarville, was sent to Beijing in the 1740s. He collected seeds of trees and bushes including those of the Tree of Heaven. Just before he died, he sent some Tree of Heaven seeds to England. They arrived in 1751 and plants from these seeds were grown throughout Europe and later, in 1784, the species was introduced in North America.Sir Joseph Banks was a very famous British plant collector, who accompanied James Cook on his first voyage from England to Oceania. The purpose of the trip for Banks was to record the plant and animal life they came across. He and his team collected examples whenever they went onto dry land. In 1769, Banks collected vast quantities of plants in the land now known as Australia. None of these plants had been recorded by Europeans before. Cook called the bay where the Endeavour hadanchored Botany Bay.Keeping plants alive during long land or sea voyages was an enormous challenge. Large numbers of seeds failed to grow after long sea voyages or trips across land between Asia and Europe. One plant explorer lost several years' work when his plants were mined with seawater.The world of plant exploration was completely changed with Dr Nathaniel Ward's invention of a tightly sealed portable glass container. This invention, called the Wardian case, allowed plants to be transported on long journeys. In 1833, Ward shipped two cases of British plants to Sydney, Australia. All the plants survived the six-month journey. In 1835, the cases made a return trip with some Australian species that had never been successfully transported before. After eight months at sea, they arrived safely in London.A British man called Robert Fortune was one of the earliest plant collectors to use Wardian cases. He made several trips to China between 1843 and 1859. At that time, there were restrictions on the movement of Europeans and so, in order to travel unnoticed, he developed his fluency in Chinese and dressed as a Chinese man, even shaving his head in the Chinese style. He experienced many adventures including huge thunderstorms in the Yellow Sea and pirates on the Yangtze River. Not only did Fortune introduce over 120 species of plants to Western gardens but he also shipped 20,000 tea plants from Shanghai to India, where a successful tea industry was established.The second half of the nineteenth century was a very important period of plant exploration. During this time many Catholic missionaries were sent to China from France. They valued the study of the natural sciences and many of the missionaries knew a lot about plants and animals. Their expeditions resulted in huge plant collections, which were sent back to France. One of the collectors was Father Farges, who collected 37 seeds from a tree that had appealed to him. This tree was later called the Dove Tree. He sent the seeds back to France in1897 but only one seed grew.Although the missionaries collected large numbers of soecimens. there was not enough material for growing particular species in Western gardens. However, European botanists were very excited with the knowledge that China had a vast variety of plants, so many plant collectors were sent on collecting trips to China. One of these collectors was E H Wilson who, in 1899, was able to collect a large quantity of seeds of the Dove Tree that Father Farges had discovered. Wilson and other plant collectors introduced many new plants to Western gardens.Reading and discussingBefore you read the text on page 38, have a quick glance at it. What is the text about? What do the pictures show you? What is the chart about?FLOWERS AND THEIR ANIMAIL POLLINATORSOver time, many flowering plants and their animal pollinators have evolved together. The plant needs the animal to pollinate it and the animal is rewarded with food called nectar when it visits the flowers. Pollen becomes attached to the animal during its visit to a flower and is then passed on to another plant's blossom on its next visit. So pollination takes place, therefore increasing the chances of the survival of the plant species.Through evolution, most flowers have adapted to attract specific types of pollinators. Bees, moths and butterflies are the most importantpollinators. Flies, wasps, beetles and other animals such as birds and bats are less common.The type of pollinator depends on the characteristics of the flower such as its colour, shape,。

英语课文高二Title: Global WarmingGlobal warming is one of the most serious problems facing the world today. It is caused by the increase in greenhouse gases, such as carbon dioxide and methane, in the atmosphere. These gases trap heat from the sun, causing the Earth's temperature to rise.The effects of global warming are already being felt. Climate change is causing more extreme weather conditions, such as heatwaves, floods, and droughts. This is having a significant impact on agriculture, wildlife, and human populations. melting glaciers and rising sea levels are also a cause for concern, as they could lead to flooding of coastal cities and islands.To combat global warming, it is essential that we take action to reduce greenhouse gas emissions. This includes using renewable energy sources, such as solar and wind power, and improving energy efficiency. We can also reduce our carbon footprint by driving less, using public transportation, and recycling.In conclusion, global warming is a major threat to our planet, but there are steps we can take to mitigate its effects. By working together, we can ensure a sustainable future for generations to come.New words and phrases:- greenhouse gases- carbon dioxide- methane- atmosphere- trap heat- Earth's temperature- climate change- extreme weather conditions- heatwaves- floods- droughts- melting glaciers- rising sea levels- flooding of coastal cities and islands- renewable energy sources- solar power- wind power- energy efficiency- carbon footprint- driving less- using public transportation - recycling- mitigation- sustainable future。

时间穿梭英语高二课文

时间穿梭英语高二课文English:The concept of time travel has long captured the human imagination, inspiring countless works of literature, film, and scientific exploration. From the ancient myths of time manipulation to the celebrated works of Wells and beyond, the idea of traveling through time has been a source of fascination and speculation. In modern physics, the possibility of time travel is a subject of theoretical study, although current scientific understanding suggests that it may not be achievable in reality. Theories such as the concept of wormholes and the bending of spacetime offer potential avenues for exploring the realm of time travel, but the practical challenges and ethical implications are vast. Despite the scientific and technological limitations, the idea of time travel continues to captivate our collective imaginations, reflecting our eternal curiosity about the mysteries of time and space.中文翻译:时间旅行的概念长久以来一直吸引着人类的想象力，启发了无数的文学作品、电影以及科学探索。

Can you name some places of interest in the world? Quite right. We have a lot of places of interest, the Great Wall, the WestLake, Zhang Jiajie, Jiuzaigou, Niagara Falls. Do you think it is necessary and important for man to protect the earth? Yes, of course. Have you ever thought that the earth is also very dirty, very ugly, I mean, not beautiful? Believe it or not, the earth is getting dirtier and dirtier. Look at the pictures on page 65, please －rivers have been polluted, rubbish is everywhere, factory chimneys have given off too much smoke causing a lot of acid rain all over the world, which has damaged not only crops, but also plants. Besides, man himself also has done a great deal of harm to the environment. Now, I'd like to ask you a few questions:1. If too many trees were cut down, what would happen? (Answer: 1. Soil lost. If too many trees were cut down, the environment would be greatly affected. The rich surface soil would be blown away by wind, or washed by rain down the hills and into rivers.)2. Silk Road once played an important part in foreign trade in China. But now it is covered with sand. What caused it? (2. Cutting trees and desert.)3. How many people are suffering from hunger?
