阅读理解。

     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. Amazingly, 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 is

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 s 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.

1. 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

2. According to Paragraph 4, a successful person is one who is believed to ______.

A. be able to work without stress

B. be more talented than other people

C. be more important than anyone else

D. be busying working without time to rest

3. Some people feel guilty when taking time to rest because they ______.

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

4. What is the main idea of this passage?

A. We should balance work with rest.

B. The Sabbath gives us permission to rest.

C. It is silly for anyone to say "I am busy."

D. We should be available to our family and friends.
