Unit 2 Language Welcome to the unit 学案（阅读热身）Emoticons or smileys explainedAn Emoticon (or Smiley) is a sequence of ordinary characters you can find on your computer keyboard. Emoticons are used in e-mail, chat, SMS（短信）and other forms of communication using computers. The most popular emoticons are the smiling faces (smileys or smilies) that people use to say “don't take what I just wrote too seriously”. If you don't see that it represents a smiling face, tip your head to the left and look at it again. The colon represents the eyes, the dash represents the nose, and the right parenthesis represents the mouth. Many people use MSN and Yahoo, for this reason I added a list with MSN and Yahoo emoticons. When using these during your chat session, they will be converted to real icons.Emoticons（情感符）Emoticons (emotional icons) are used to compensate for the inability to convey voice inflections, facial expressions, and bodily gestures in written communication. Some emoticons are better known as “smileys”. Emoticons can be very effective toward avoiding misinterpretation of the writer’s intents. While there are no standard definitions for the following emoticons, we have supplied their most usual meanings. Most emoticons will look like a face (eyes, nose, and mouth) when rotated 90 degree clockwise.:) or :-) Expresses happiness, sarcasm, or joke:( or :-( Expresses unhappiness:] or :-] Expresses jovial happiness:[ or :-[ Expresses despondent unhappiness:D or :-D Expresses jovial happiness:I or :-I Expresses indifference:-/ or :-\ Indicates undecided, confused, or skeptical. Also :/ or :\.:Q or :-Q Expresses confusion:S or :-S Expresses incoherence or loss of words:@ or :-@ Expresses shock or screaming:O or :-O Indicates surprise, yelling or realization of an error ("uh oh!")Acronyms（首字母缩略词）AAMOF as a matter of fact BBFN bye bye for nowBFN bye for now BTW by the wayBYKT but you knew that CMIIW correct me if I'm wrongEOL end of lecture FAQ frequently asked question(s)FITB fill in the blank FWIW for what it's worthFYI for your information HTH hope this helpsIAC in any case IAE in any eventICL in Christian love IMCO in my considered opinionIMHO in my humble opinion IMNSHO i n my not so humble opinionIMO in my opinion IOW in other wordsLOL lots of luck or laughing out loud MGB may God blessMHOTY my hat's off to you NRN no reply necessaryOIC oh, I see OTOH on the other handROF rolling on the floor ROFL rolling on the floor laughingROTFL rolling on the floor laughing RSN real soon nowSITD still in the dark TIA thanks in advanceTIC tongue in cheek TTYL talk to you laterTYVM thank you very much WYSIWYG what you see is what you get<G> Grinning<J> Joking<L> Laughing<S> Smiling<Y> YawningSign LanguageFor many years, no one could communicate with people who had been born without hearing. These deaf people were not able to use a spoken language.But, beginning in the 1700s, the deaf were taught a special language. Using this language, they could share thoughts and ideas with others. The language they used was a language without sound. It was a sign language.How did this sign language work? The deaf were taught to make certain movements using their hands, faces, and bodies. These movements stood for things and ideas. People might move their forefingers across their lips. This meant, “you are not telling the truth.”They might tap their chins (下巴) with three fingers. This meant “my uncle.”The deaf were also taught to use a finger alphabet. They used their fingers to make the letters of the alphabet. In this way, they spelled out words. Some deaf people could spell out words at a speed of 130 words per minute. Sign language and finger spelling are not used as much as they once were. Today, the deaf are taught to understand others by watching their lips. They are also taught how to speak.Introduction to BrailleLouis Braille invented "Braille", a world wide system of embossed type used by blind and partially sighted people for reading and writing. It has been adapted to almost every known language, from Albanian to Zulu.He died in 1852 and, for a while, it seemed as if this system would die with the inventor. Thankfully a few key people realised the importance of this invention. In 1868, Dr Thomas Armitage led a group of four blind men to found the British and Foreign Society for Improving the Embossed Literature of the Blind.This small band of friends grew and grew to become Royal National Institute of the Blind (RNIB). We are now the largest publisher of Braille in Europe. Our pioneering work helps anyone with a sight problem - not just with Braille, Talking Books and computer training, for example, but with imaginative and practical solutions to everyday challenges.Where does the story begin?Louis Braille was born in a small town near Paris in 1809. One day when Louis Braille was a small boy, he crept into his father's workshop to play. He had often seen his father making shoes and he decided he would like to try. He picked up an awl, a sharp, pointed tool used for making holes in leather. As he bent over, the awl slipped and pierced his eye, destroying it forever. Some time later his other eye became infected by the first and he lost his sight altogether. He was aged only 4, but still went on to become one of the most famous Frenchmen ever to live.Louis Braille's school yearsDespite his sight loss the young child attended the village school with his sighted friends fortwo years. Eventually it became clear that he would not be able to learn much more, largely because he could not read or write. Without an education it was likely that he would have to beg on the streets, like other blind people at that time.At the age of ten he was lucky enough to be sent to a school for blind boys in Paris, one of the first in the world. Conditions in the school were very harsh. The building was damp and unhealthy and discipline was severe. Pupils who misbehaved were beaten, locked up and given stale bread and water. In fact, this kind of discipline was common in all schools at that time. Life was harsh for nearly everyone and most sighted children left school at the age of 12 and went to work in factories or in mines.At the school in Paris the blind pupils were taught practical skills like chair caning and slipper making so that when they left the school they would be able to make a living. Once a week, after lunch, the boys were taken for a walk in the park, linked together by a long rope.They were also taught to read but not to write. The letters they read were raised above the surface of the page so that they could feel them with their fingertips. This form of writing was very difficult to read because it was very hard to tell the letters apart. The letters were printed by pressing copper wire into one side of the paper to make a raised shape on the other. Because each individual letter had to be made out of wire first and because the wire then had to be forced into the paper with a press blind people were unable to write anything for themselves.One day something happened that changed the lives of blind people forever. In 1821, a soldier named Charles Barbier visited Louis' school. He bought with him a system he had invented called "night writing". Night writing had originally been designed so that soldiers could pass instructions along trenches at night without having to talk and give their positions away. It consisted of twelve raised dots which could be combined to represent different sounds. Unfortunately it proved to be too complex for soldiers to master and was therefore rejected by the army.How did he develop Braille?The young Louis Braille quickly realised how useful this system of raised dots could be, provided it was simplified. Over the next few months he experimented with different systems until he found an ideal system using six dots. He continued to work on the scheme for several years after, developing separate codes for maths and music. In 1827 the first book in Braille was published.Even so, the new system did not catch on immediately. Sighted people did not understand how useful Braille could be and one head teacher at the school even banned the children from learning it. Fortunately this seemed to have the effect of encouraging the children even more and they took to learning it in secret. Eventually even sighted people began to realise the benefits of the new system.Not only could people with sight problems read Braille but they could also write it for themselves using a simple stylus to make the dots. For the first time blind and partially sighted people began to be truly independent and to take control of their own lives.What did he go on to do?Louis Braille eventually became a teacher in the school where he had been a student. He was admired and respected by his pupils but, unfortunately, he did not live to see his system widely adopted. He had always been plagued by ill health and in 1852, at the age of 43, he died from tuberculosis.In France itself, Louis Braille's achievement was finally recognised by the state. In 1952 his body was moved to Paris where it was buried in the Pantheon, the home of France's national heroes.Dance and communicationDistance InformationWith increasing distance the number of circuits (8's) per unit time decreases and the length and duration of the individual circuits increases. For example, for a goal at 100 meters it makes 10 short circuits in 15 seconds but at 3 km only 3 long circuits in the same time. The duration of the wagging part has the best correlation with distance. The distance is calculated based on the expenditure of energy on the flight towards the source (a head-wind increases it). Each recruited bee averages many dance circuits or even severaldances from different bees to calculate the distance.For each bee species a distance-frequency curve canbe plotted. It is remarkably precise, especially if thedistance is not close to their foraging range limit.Compass InformationIf the dance floor is horizontal (the least common casein Nature), the indication of direction is straight-forward: the wagging (straight) portion of the eight-figure dance points towards the food source (and in the same direction as the bee runs through it). But, what does the dancing bee use as compass to accurately point in the right direction? The bee reference is the direction of the sun. This can be demonstrated easily by covering the sky and using a lamp as an artificial sun: the direction of dancing will rotate, always maintaining the same angle with the lamp as the angle with the sun during direct flight towards the food.。

◆教学目标By the end of this section, students will be able to:1. watch the video and get the basic knowledge of three types of natural disasters;2. talk about other different types of natural disasters;3. share with peers the information of the natural disasters in history.◆教学建议1. Have students watch the video and finish the blank-filling exercise on page 15. Possible answera sudden shaking; hot gases; earth and rock2. Have students answer the two questions on page 15.Possible answer1. Another type of natural disaster that I know about is tsunamis. A tsunami isa series of huge waves, often caused by an earthquake or volcanic eruption. Tsunamis often damage buildings severely and they can be deadly to humans.The 2004 Indian Ocean Tsunami killed more than 200,000 people.2. Afghanistan Blizzard in 2008, the second worst blizzard in modern historywith regard to casualties, had an estimated death toll of more than 900 due to temperatures that fell below —30℃ with up to 180 centimetres of snow in the mountainous regions. Some were frozen to death, and some died when their vehicles were blocked by snowdrifts. It also claimed more than 100,000 sheepand goats and 315,000 cattle.3. Have students answer the following questions.(1) How many small earthquakes happen every year?Possible answerSeveral million small earthquakes happen every year.(2) What can the volcanic gas and ash cause?Possible answerThey can cause acid rain and even storms.(3) What are landslides often caused by?Possible answerHeavy rainfall, earthquakes, volcanic eruptions or other natural disasters. Sometimes human activities such as cutting down forests can also cause landslides. Video scriptNarrator: A natural disaster is a sudden natural event that causes great damage and suffering. It can happen anywhere, at any time. Let’s look at some examples.29 An earthquake is a sudden shaking of the earth’s surface, caused by the movement of plates underground. Earthquakes are most common where plates meet. Several million small earthquakes happen every year, but most do not cause any damage. Serious earthquakes, however, can destroy entire cities.When a terrible earthquake hit San Francisco in 1906, about 3,000 people diedand over 80 per cent of the city was destroyed.A volcanic eruption occurs when hot gases, volcanic ash and even rocks escape through a large opening at the top of a volcano. The gases and ash can causeacid rain and even storms. The hot liquid rock moving down the volcano burnseverything and anything in its way. The eruption of Mount St Helens in 1980 was the worst volcanic disaster in the history of the United States. It killed 57 people and about 7,000 large animals.A landslide happens when a large amount of earth and rock falls down a hill or mountain. Landslides are often caused by heavy rainfall, earthquakes, volcanic eruptions or other natural disasters. Sometimes they are also caused by human activities such as cutting down forests.Serious landslides can cause whole mountainsides to roll away. Villages or towns located in the path of such landslides can be completely destroyed. In 2014, a landslide in India killed at least 150 people.。
