On December 14th 1911, he stood victoriously at the South Pole. He reached a goal that was the dream of many men. For the first time, human voices broke the awesome silence of the worlds southernmost point.Robert Falcon Scott was born at Outlands on June 6, 1868. He had a race with Roald Amunsden to the South Pole, and he and his four companions arrived one month later than Roald. But unfortunately, on their way back, all of them died of hunger and extremely cold.Look at the title and photos and guess the answers to these questions.(1) Which Pole did they race to?(The South Pole.)(2) When did they go?(1910-1911)(3 )Who reached the Pole first?(Amundsen)II Reading1.Read the text more carefully.

Scott failed because he and his men had to push the sledges themselves when the motor sledges broke down and the ponies had difficulties with the snow and the cold.)(2)What did Scotts expedition achieve?(They reached the Pole although they didnt win the race and they became heroes because of their courage. They collected rocks that proved Antarctica had once been covered by plants.)(3) Why did Scott and his men become heroes?(They became heroes because, although they died on the return journey, they showed remarkable courage all the time.)IV Language points1. expedition : 探险;远征;探险队go on an expedition 去探险make an expedition 远征，探险a polar expedition 极地探险队2. prepare V.prepare fore.g. Please prepare a table for dinner.Hope for the best and prepare for the worst.preparation n.in preparation for 为作准备They put chairs in the school hall in preparation for the concerts.Joe is training in preparation for the next football match.in preparation 在准备中Plans for selling the new product are now in preparation.3. wait for sb. / sth.
