综英教程4课后问题答案整理

UNIT1 1．Why does the speaker urge people to be patient? Because he understands that the war is long and tough. it is not to end in months but in years. he tells the people there that however long the war last, the final victory belongs to Britain. but at the same time he makes it clear that not everyday is an opportunity to take action. they have yet to wait and persevere. 2．why does the speaker advise the British people to treat triumph and disaster in the same way? Because he thinks that both triumph and disaster are deceptive in that people can make things out far worse than they really are when they are in triumph. what is the change in the widespread mood referred to in p5? When Britain came under the heavy air attacks by Germany .many other nations thought that Britain was finished. As the country stood the ordeal to their great surprise, those nations changed their view. 3．why does the speaker change darker into sterner? Because he has a strong conviction of victory. The 2terms have different implications. when used in the text to refer to the days of war, ”darker days” emphasizes the negative aspect of the event and shows the user’s pessimism.’ sterner days’ ,though identical in its reference ,suggests optimism and pride in having the chance to rise the challenge. 4．Do you think the speaker had achieved his purpose by the end of his speech? Yes, I do. By paying a visit to Harrow School and making a speech there, Churchill not only encouraged the audience of his speech but the British people in general to continue to fight rather than surrender to their enemy.
