One morning a few years ago，Harvard President Neil Rudenstine overslept. For this busy man，it was a sort of alarm: after years of non-stop hard work，he might wear himself out and die an early death.
Only after a week's leave—during which he read novels, listened to music and walked with his wife on a beach—was Rudenstine able to return to work.
In our modern life, we have lost the rhythm between action and rest. Surprisingly, within this world there is a universal but silly saying:“I am so busy.”
We say this to one another as if our tireless efforts were a talent by nature and an ability to successfully deal with stress. The busier we are, the more important we seem to ourselves and, we imagine, to others. To be unavailable to our friends and family, and to be unable to find time to relax—this has become the model of a successful life.
Because we do not rest, we lose our way. We miss the guide telling us where to go, the food providing us with strength, the quiet giving us wisdom.
How have we allowed this to happen? I believe it is this: we have forgotten the Sabbath, the day of the week—for followers of some religions—for rest and praying. It is a day when we are not supposed to work, a time when we devote ourselves to enjoying and celebrating what is beautiful. It is a good time to bless our children and loved ones, give thanks, share meals，walk and sleep. It is a time for us to take a rest, to put our work aside, trusting that there are larger forces at work taking care of the world.
Rest is a spiritual and biological need；however，in our strong ambition to be successful and care for our many responsibilities，we may feel terribly guilty when we take time to rest. The Sabbath gives us permission to stop work. In fact, “Remember the Sabbath ”is more than simply permission to rest；it is a rule to obey and a principle to follow.
50. The “alarm” in the first paragraph refers to “______”.
　　A. a signal of stress                                  B. a warning of danger
　　C. a sign of age                                      D. a spread of disease

　　A. be able to work without stress　　            B. be more talented than other people
　　C. be more important than anyone else　　 D. be busy working without time to rest

　　A. think that taking a rest means lacking ambitions
　　B. fail to realize that rest is an essential part of life
　　C. fail to realize that religions force them to rest
　　D. think that taking a rest means being lazy
53. What is the main idea of this passage?
　　A. We should balance work with rest.
　　B. The Sabbath givers us permission to rest.
　　C. It is silly for anyone to say “I am so busy.”
　　D. We should be available to our family and friends.

　　The curtain on the 2008 US presidential election finally rose last month as Requblican Senator(参议员) John McCain and Democratic Senator Barack Obama were formally selected as candidates of the two major parties.This may be one of the hardest decisions voters have to make between two appealing candidates.The big question for voters,as they face both an economic downturn and international threats,is :who will they elect? A young first - term senator promising change and new ideas,or a longtime senator with strong military experience and a reputation as a maverick(特立独行的人)？
　　American voters have never seen a candidate quite like Obama.He has a white mother from the US and a black fater from Kenya who left the family when Obama was very young.He spent part of his youth in Indonesia.
　　However,McCain has a very different life story.
　　He grew up in a Navy family and was a daring pilot during the Vietnam War in the 1960s. When Obama was in kindergarten in Indonesia,McCain's plane was shot down over Ietenam and he became a prisoner of war.McCain could have been set free if he disowned America but he refused and so was held for five years.
　　"We need a president who is very,very old,"McCain joked at his age as many others do.If elected,he would be 72 when he takes office and the oldest man to step in.
　　So in the end,the election may depend on several factors that are hard to judge:Will Obama's race matter to a significant number of voters ? Will workingclass whites who tended to support his primary (党内初选) oponent,Hillary Clinton,vote for Obama? And perhaps most important of all,will uncertain voters be more attracted to Obama's vision or to McCain's experience?
　　Whatever happens,one thing is clear,however:Whoever walks into the White House on January 20,2009,will find huge challenges waiting for him in the Oval Office,both at home and abroad.
　　64.______makes the result of the election hard to predict.
　　　A.Whether working class whites care about Obama's inexperience
　　　B.The economic trouble the country now faces
　　　C.Who uncertain voters will finally decide to vote for
　　　D.McCain being too old to govern the country
　　65.The appeal in Obama as a presidential candidate lies in _________
　　　A.his multi - cultural background
　　　B.his belife in tradition
　　　C.his inexperience in politics
　　　D.his fantastic promises
　　66.The word "disown" in Paragraph 6 means closest to ______.
