rescued?Why?Suggested answers:1.The answers vary.2.Yes,they were finally rescued.Because the title of the text is“THE REWARD FOR PERSEVERANCE”,maybe that they were rescued is their reward.Activity 2Reading for detailed informationRead the text quickly and answer the questions.1.What did the men eat and drink on the island?2.What were the dangers of living on the island?3.How did the men stay in good spirits while waiting to be rescued?4.What do you think were the key reasons for their survival?Suggested answers:1.Their only food was the meat of the sea creatures and they drank the watermelt

kept them optimistic and helped them deal with their fears.2.I would have trusted Shackleton if I were one of the men.Shackleton was a famous captain, whose charm of personality, such as determination, commitment,courage and wisdom,deeply influenced people and people all had belief in him.So did I.StepⅠ Write an essay about Shackleton and Endurance.Activity1 Combining all the information from the text,discuss with your partner and write down the structure of the story.Suggested answers:paragraph 1:Summary of the whole story(who,what,when,where,why,how).paragraph 2:What I think about the characters in the story(struggles they faced,their actions and motives,my comments).paragraph 3:How the story made me feel and my overall impressions of theexpedition.Activity 2 Write the essay independentlyOne possible version:This story is about the 1914-1916 expedition by Ernest Shackleton to make the first land crossing of Antarctica.For this task he used the ship Endurance with a 28-man crew,including one stowaway.Shackleton is described as calm and brave and takes his crew’s safety very seriously.The rest of the crew are also brave,though a few are not very positive,and all were at times understandably worried and desperate about their situation.Overall though,they remained positive.This was helped by the good relationship Shackleton had with his crew who trusted him and knew he would do his best to save them.The crew faced great troubles once Endurance got stuck in the ice.Soon they had to abandon the ship and camp on the ice.They had to face the extreme weather and cold as well as the dangerous environment and all with limited supplies.All of this added to the mental challenge,so they had to maintain a positive state of mind.Shackleton’s motive was always to make sure his crew survived,and theirs was to last until he had found help.What I like most about this story is that although their expedition failed in achieving its goal,it was not the disaster it could have been.This was due to Shackleton’s perseverance in getting help and the crew’s bravery in surviving for so long.My impression of them is very positive as they must have struggled greatly in such a position of adversity.I felt very happy when I learnt that the whole crew survived.Activity3 Exchange the draft with a partner,evaluate and polish the draft according to the checklist.Activity4 Present and ShareAsk some students to present their works in front of the class and evaluate their advantages and disadvantages.StepⅠ Homework请同学们写出心目中一位大家较为熟悉的、克服困难后成功的名人,描述他/她遇到什么困难,是如何以乐观坚毅的态度应对人生的逆境和挫折的,对你的学习和生活有什么启发。
