Unit 2 Sailing the oceans当今航海技术达到前所未有的水平，那么你知道古代一些有关航海方面的仪器吗？Sinan，the ancient Chinese passIt was invented by Zhang Heng in the Han Dynasty.It is madeup of a bronze foundation (青铜底盘) and magnetic spoon(磁勺)which is made of natural magnet，positioned right in the centerof the foundation.The handle of the spoon points to the south，while the other side points to the north.When the Sinan is in the still，the handle of the spoon points to the south because of the influence of the terrestrial magnetism (地磁)．AstrolabeIt has 17 stars listed as well as a map of the sky overhead(for 37 degrees) and the ecliptic (黄道)．The time of day or nightis on the outside edge with noon at the top of the Astrolabe andmidnight at the bottom.It es with a carrying chain，a pouch，and a book on its use.The reverse side has a sight for measuringthe elevations of the heavenly bodies.SextantThe sextant is a navigational instrument for measuring theangle between the horizon and some object in the sky.First a sailorlooks at the horizon through an eyepiece.At the see light fromthe sun or a star reflected off a small mirror on top of theinstrument，onto a second mirror and into the eyepiece.The navigator can then see two images，the horizon and the sun side by side.He can then measure the angle between them on a scale at the bottom of the instrument.The scale goes from 0 to 120 degrees.An earlier instrument，called a quadrant，measured in angle in the same way but it could only measure angles from 0 to 90 degrees.Nautical chartNautical charts are maps of the depth of the sea and thecurrents of the oceans.They provide modern sailors with routesthrough the seas，rather like roads through the countryside.Theinformation began to be collected in the nineteenth century andhas continued to be updated ever since.These charts were not available to Captain Bligh or Zheng He.两个诱思问题1．What is the theory of the Sinan invented by Zhang Heng?2．Why were the Nautical charts not able to be used by Captain Bligh or Zheng He?【答案】1．The influence of the terrestrial magnetism.2．Because the information began to be collected in the nineteenth century.Section ⅠReading (Warming Up, Prereading，Reading & prehending)Ⅰ.根据词性及英文释义写出单词的正确形式1．n．kindness；forgiveness2．n．activity of exploring3．adj.above one's head4．adj.at sea not far from land5．adj.made or done without any plan6．adj.difficult to use7．n．act of mentioning；act of looking at for information8．adj.light and that can be(easily) carried or moved【答案】 1.mercy 2.exploration 3.overhead4.offshore5.random6.awkward7.reference8.portableⅡ.短语填空may well；at the mercy of；work out；be close to；the number of；pare with；in relation to；rather than1．I prefer to walk there take a bus.2．The boat was the rapid river.3．This novel bee a classic.4． those who are suffering，we are better off.5．I believe that you can this problem by yourself.【答案】 1.rather than 2.at the mercy of3.may well4.pared with5.work outⅠ.阅读P12－13课文内容，从三个选项中选择最佳答案1．How many traditional methods used by seamen are mentioned in the passage?A．Four.

find new places within an already identified island or continent Explorer is someone who travels into or through a place in order to learn about it. Very often navigators are also explorers.
He (1371-1433) sailed from China to many places throughout South Pacific, Indian Ocean, Persian Gulf and distant Africa in seven epic voyages from 1405 to 1433, some 80 years before Columbus's voyages.
He (1728-1779) was the greatest Britain navigator. He enlisted in the Royal Navy in 1755. In 1768 he was promoted and sent to the Pacific where he surveyed Tahiti, New Zealand, and Australia. On his famous 2nd expedition (1772-75) he explored Antarctica. In 1776 in his third and final voyage, he explored the West coast of North America and discovered the Hawaiian Islands.

Unit 2 Sailing the oceansPart One: Teaching DesignPeriod 1: A sample lesson plan for reading(SAILING THE OCEANS)AimsTo help students read about sailing the oceansTo help students learn about the predicateProcedures■Warming up by leaning about navigatorWhat is a navigator?A navigator is the person onboard a ship responsible for the navigation of the vessel. On aircraft, the position may also be referred to as a flight officer. The navigator's responsibilities include planning the journey, advising the captain (or pilot) while en route, and ensuring that hazards or obstacles are avoided.What is exploration?Exploration is the act of searching or traveling for the purpose of discovery, e.g. of unknown regions, including space (space exploration), or oil, gas, coal, ores, water (also known as prospecting), or information.Exploration has existed as long as human beings, but its peak is seen as being during the Age of Exploration when European navigators travelled around the world.In scientific research, exploration is one of three purposes of research (the other two being description and explanation). Exploration is the attempt to develop an initial, rough understanding of some phenomenon.■Warming up by talking about Zheng He's Seven VoyagesIn July 11, 1405, the eunuch Zheng He of the Ming Dynasty royal court set out on his first overseas voyage.In the following 28 years, this navigator proceeded to carry out six more voyages, accompanied by a huge entourage of nearly 30,000 people. By traveling throughout Southeast Asia, and around the Indian Ocean tothe Red Sea and East Africa, he also landed at over thirty different nations.He was the earliest largest scale navigation in world history, coming more than halfa century earlier than Columbus'famous exploits...■Warming up by looking and listeningHello, class. Do you know this man? Yes, he is Marco Polo. Marco Polo (1254-1324), is probably the most famous Westerner traveled on the Silk Road. He excelled all the other travelers in his determination, his writing, and his influence. His journey through Asia lasted 24 years. He reached further than any of his predecessors, beyond Mongolia to China. He became a confidant of Kublai Khan (1214-1294). He traveled the whole of China and returned to tell the tale, which became the greatest travelogue.I. Pre-readingWhat are navigational instruments?●Navigational instruments were built in the age of exploration to guide the explorers to their destinations.●navigational instrument - an instrument used for navigating◇artificial horizon, flight indicator, gyro horizon - a navigational instrument based on a gyroscope; provides an artificial horizon for the pilot◇compass - navigational instrument for finding directions◇depth finder - navigational instrument used to measure the depth of a body of water (as by ultrasound or radar)◇inclinometer - an instrument showing the angle that an aircraft makes with the horizon◇instrument - a device that requires skill for proper use◇asdic, echo sounder, sonar - a measuring instrument that sends out an acoustic pulse in water and measures distances in terms of the time for the echo of the pulse to return; sonar is an acronym for sound navigation ranging;asdic is an acronym for anti-submarine detection investigation committeeII.

Closing down by reading more about sailing the oceansSailing the oceansFor thousands of years, people have been sailing across the oceans and around the world. Knowledge of ocean currents and wind patterns has allowed people to reliably reach their destinations even after crossing huge expanses of open ocean.In this photograph, a sailboat uses wind and currents to move among the islands of Micronesia. Before modern navigational techniques were developed, navigators in the South Pacific relied on stick charts to indicate island locations relative to winds andcurrents.Today, racing sailboats is a sport, and teams test their skills by racing around the world. Navigation now relies on satellites, but knowledge of wind patterns, ocean currents, and potential obstacles in unfamiliar waters is still essential for sailing.In this investigation, you'll plot a course for racing around the world in a sailboat. You'll explore some of the obstacles you might encounter on your route; then you'll have the opportunity to revise your route to improve your speed.。
