Module 9 Unit 2 Sailing the oceansDiscuss1. How do you think seamen found their way before modern accurate methods of navigation were invented?Kept close to the shore, used nature such as the sun, wind, birds, tide, etc, to help them, and used some of the instruments including a compass, astrolabe, etc.2. Which do you think was easier to work out: latitude or longitude?Latitude, because it was used to measure how far you had traveled from land ona straight line. It was discovered a long time before longitude.3. Can you identify these early navigational instruments seamen used and explain how they are used?1) compass ( in ancient China)2) astrolabe3) sextant4) sea / nautical / marine chart4. Which ones do you think are still used today?Sea charts are still used today.ReadingComprehending1.

To measure the position of the shipC. To measure the speed of the shipD. To tell the time2) Why are speed and time important in working out the longitude of a ship?Speed and time are important in finding out the longitude of a ship because the earth moves fifteen degrees westwards every hour. If you know your direction, speed and time, you can work out the approximate longitude or changein your position in relation to the stars.3) Why is the position of the sun and various stars useful for working out latitude?The position of the sun and stars are useful for working out latitude because they are fixed points in the sky and their movements in relation to the earth are already known. So they can be used to measure a ship's position.2. Suppose you were a sea captain aiming to sail round Africa. Discuss in groups:1) What skills would you seek in your sailors?2) What problems would you anticipate for this journey?3. Read the passage again and use the information to analyze the navigational skills.Using nature1. To find the ship’s position at sea a sailor used the North Star and the sun.2.

A卷学业水平达标【说明】本试卷满分120分，考试时间100分钟Ⅰ.阅读理解(共15小题；每小题2分，满分30分)ASitting on the peaceful coast of the Galapagos Islands, Ecuador, watching the sun move quietly into the sea, you shouldn’t forget that Charles Darwin(1809～1882)arrived here in 1835.He stayed on the islands for five weeks, observing various animals.This finally inspired (启发) his famous work, On the Origin of Species.You can certainly follow Darwin’s footsteps and enjoy a trip from four to seven days to the islands.The islands are certainly a paradise (天堂) for wildlife, as there are no natural killers on the islands and the number of boats and visitors is under government control.Though you cannot walk freely as Darwin did about 200 years ago, each day is as impressive as it could be.The most wellknown animal of the Galapagos is the giant tortoise (巨型陆龟), which can be seen moving slowly around the highlands of Santa Cruz, the second largest island in the archipelago (群岛)．Some of these creatures are so old that they might have been seen in their youth by Darwin himself.Despite strict control over activities and timing, your stay on the Galapagos will be remembered as a chain of incomparable pictures: diving with sea lions that swim and play within inches of you; feeling small sharks touch your feet as you swim; and, most magically, seeing a whale and her baby surface with a great breath of air.Traveling between the islands and observing the wildlife that so inspired Darwin, you will feel as though you are getting a special view of an untouched world.At night you will sleep on board the ship, leaving the wildlife in complete occupation of the islands, which are as undisturbed now as they have been since the beginning of time.语篇解读：文章主要讲述了Galapagos Islands上的景点和人们游玩的感受。

So they can be used to measure a ship's position.（P13）III.
