【正文】 ant of rhyme. Step 2. Whilelistening Listen to the story (Part 1) and find the information about it. (When, where, who, what?) When: 18th century? (No, not mentioned) Where: on a ship Who: sailors / mariners What: One of the sailors kills a bird that brings good luck to the ship, by doing which he has brought bad luck and death to the sailors. Listen to part 1 for the second time and finish the following true or false questions. This poem was written by a British poet Samuel Taylor Coleridge in the 1700s. (T) In the poem, one of the sailors kills a fish under the ship. (F) It is believed that the animal he kills is one that brings good luck to the ship. (T) Other sailors are so frightened and angry that they kill the sailor. (F) The sailors are extremely thirsty but they can‘t drink the water in the sea, because it is too dirty. (F) Listen to part 1 for the third time and answer the following questions: Who tells the story in the poem? What does one of the sailors do? What do you think will happen next? Why are the other sailors frightened? Listen to part 2 and plete the following sentences. Finally they decide that he must die － _______ the mariner who _______ the bird. He must _____ _______ it all and will ______ by having to tell the story… _____ ______ on the ship, _________ on the ocean, the mariner suffers from _______and ______. His story _____, the ________ mariner says _________ and asks them to learn from his ___________. Keys: 1) except, shot。 2) live through, pay 3) Left alone, drifting, loneliness, fear。 4) told, ancient, farewell, sufferings Listen to part 2 again and answer the following questions: What happens to the sailors? What happens to the mariner? Why is the person telling the story? Who is the person actually? Step 3. Postlistening Reflection: What do you learn from this story? － Everything existing in the world has their own certain values, we should understand and respect them. Creation Work with partner and try to e up with a good, scary story like the one about the mariner. Step 4. Homework Think as many examples as possible to illustrate water properties. Period 3 Reading Teaching Aims and Demands: 1. To help the Ss learn some language knowledge, patterns and language items as well as science knowledge. 2. To develop the Ss‘ ability of reading prehension through reading activities. 3. To help the Ss understand why water is so important to us and what we can do to protect water. Teaching Difficult Point: 1. Understand each part of the passage. 2. To help improve Ss‘ municative skills by introducing the proper use of ―Modal verbs‖. Teaching Aids: A recorder, some slides Teaching Procedures: Step1: Lead in Ask some questions to make students get to know something about water. Step 2. Fast Reading Ss read the bold words in the passage and understand the structure of the passage. How many parts are there in the passage? Ss read and get the main ideas of each part. Part 1(para1): the properties of water。 Part2(Para2): chemical structure of waterH2O Part3(Para3): salinity the percentage of salt. Part4(Para4): Density Part5(Para5): heat capacity Part6(Para67) Ocean motion Step 3. Careful Reading Read the passage carefully and answer the following questions. 1. What are the properties of water? Water is polar. Water is liquid at room temperature. Water has a relatively high freezing point. Water has density 1, 000 kg/m3. Water has high heat capacity. … 2. What causes water to have such unique properties? － Its molecule form / chemical structure. 3. What is water molecule like? Chemical structure: two hydrogen atoms and one oxygen atom. Different parts of it: a slightly positive end and a slightly negative end, so it is polar. The function of it: it causes water to be able to dissolve both solids and gases, and that‘s why water can break down nutrients quickly. 4. Do pure water and salt water have the same chemical structure? Does pure water have salinity? Qs: 1) What‘s salinity? 2) What is sea / salt water? － A mixture of pure water, dissolved gases and solids. 3) How does salinity affect water? 4) How does it affect water‘s weight and freezing point? － The higher salinity water has, the heavier the water is. The higher salinity is, the lower the freezing point of water is. 5. Salinity also has something to do with the density of water. The higher salinity is, the higher density of water is. Qs: 1) What is density? 2) How is density measured? 3) Which is denser, water or oil? 4) What will happen when water and oil are in the same container? What does this phenomenon illustrate? － Oil floats on water. A less dense substance floats on a denser substance. 5) Does water in the same ocean have the same density? － No. Denser water sinks and pushes less dense water to the surface. 6. That‘s why the ocean water will never stop moving. Qs: 1) What does ocean motion mean? 2) How does ocean motion work? － Denser water sinks and pushes less dense water to the surface. Ocean motion helps move nutrients around and adds energy to the marine ecosystems. 3) What causes ocean motion? － Changes in salinity and temperature. 7. The temperature of the ocean water always keeps steady, making the ocean a safe and fortable habitat. Do you know why? － Water has a relatively high heat capacity. Qs: 1) What is heat capacity? 2) What‘s the function of heat capacity? － It determines how a substance absorbs and releases heat。 It keeps water temperature steady。 It keeps the earth‘s temperature steady.
