“How did you do it, Dad ? How have you   21   not to take a drink for almost 20 years? ”It took me almost 20 years to have the  22  to even ask my father this very  23 question.

When Dad first 24  drinking, the whole family was on pins and needles  25  he got into a situation that, in the past, would have started him drinking again.For a few years we were  26  to bring it up for fear that the drinking would begin again.

“I had this little  27  that I would recite to myself  28  four to five times a day ” was Dad’s  29 to my 18-year-old unasked question.“The  30  were an instant relief and constant reminder to me that things were never so  31  that I could not handle them,”Dad said.And then he  32  the poem with me.The poem’s simple, yet profound (深奥的) words  33  became part of my daily routine as well.

About a month after this talk with my father,I  34  a gift in the mail from a friend of mine. It was a book of affirmations (断言) with one affirmation listed for each  35  of the year.

I 36  opened the book to the page of my birthday to see what words of wisdom this book had in store for me. 37  of disbelief and appreciation rolled down my face.There,on my birthday ,was the  38  poem that had helped my  39 for all these years! It is called The Sereniry Prayer.

God,give me the Serenity（平静）to accept the things I cannot change,the Courage to  40  the things I can,and the Wisdom to know the difference.

Not only did the students ask for changes in the list of required subjects，but they also demanded the right to choose their courses according to their own taste and future needs．No more fixed programs,no guidance from educators and professors．All they wanted was to get their degree as fast as possible and go to work．

Although the educators didn’t all agree；a majority recognized that time had indeed changed and that education should perhaps adapt itself to the realities of modern society．Colleges and universities revised their programs to include a large number of specialized courses in business，nursing，engineering，and other professional fields．In the 1960s they also added courses requested by the students because they considered them“relevant(相关的)”(Women Studies，Revolution，or Black History)or useful(glass blowing，infant care，slow running，or family life)．The students were granted the right to choose their courses as they wished．Many traditional subjects had to be dropped，including history and foreign languages；the liberal education courses that were still useful were often neglected(忽视)by the students，who didn’t feel like working hard to learn something that was not required for graduation．

Whether the revised programs have helped college graduates to find employment quickly is not clear．But after fifteen or twenty years of experimentation，they have raised a lot of criticism．Some of it comes from the graduates themselves,who discover that their practical knowledge is neither deep nor flexible(灵活的)．As soon as they progress to higher positions，they find that they need management training and more study in their own field．Besides，they feel disabled by their lack of general knowledge,for example，by their ignorance of the language and culture of the foreigners with whom they are doing business. Most of all they suffer from their inability to use English，their own language，easily and properly.

1.The students also demanded      ，besides a change of program.

2.What was the reaction of the colleges towards the students’demand?

3.Who is it that criticized the new system of education?

4.In the opinion of the critics，the main problems are      .

In only two decades Asian Americans have become the fastest-growing US minority．As their children began moving up through the nation’s schools，it became clear that a new kind of culture was coming out．Their achievements are made in the nation’s best universities，where mathematics，science and engineering departments have taken on a decidedly Asian character.This special liking for mathematics and science is partly explained by the fact that Asian-American students who began their education abroad arrived in the U.S. with a solid grounding in mathematics but little or no knowledge of English.They are also influenced by the promise of a good job after college．Asians feel there will be less unfair treatment in areas like mathematics and science because they will be judged more objectively(客观)．And the money spent on education is more immediately returned in something like engineering than with an arts degree．

Most Asian-American students owe their success to the influence of parents who are determined that their children should take full advantage of what the American educational system has to offer.An effective measure of parental attention is homework. Asian parents spend more time with their children than American parents do，and it helps．Many researchers also believe there is something in Asian culture，such as family value，the importance of education and so on that lead to their success.

Both explanations for academic success worry Asian Americans because of fears that they could cause the native Americans’unhappiness．Many can remember when Chinese,Japanese and Filipino immigrants(移民)were unequally treated because of social separation．Indeed，it was not until 1952 that laws were laid down giving all Asian immigrants the right to citizenship.

1.Few Asian-American students major in human sciences mainly because       .

2.Asian-Americans prefer something like engineering to an arts degree because________.

3.While making great achievements at college，Asian-American students________.

4.According to the passage，the major factors determining the success of Asian-Americans are   .

More and more scientific experiments prove that physical exercise can reduce the dangers of some illnesses in middle-aged persons．Exercise strengthens the heart muscle，reduces blood pressure and help to prevent muscles from changing into fat．Physical exercise is just as important for children．

Exercise and food affect growing speed in young lab animals．Baby mice start running as soon as they are big enough to use an exercise wheel in their cage．If  they get extra food and run a lot，they will grow as much as 1.5 times bigger than normal．

The same differences in growing speed might be found between active and inactive children．Physical exercise helps active children grow faster than inactive children．One experiment shows that the brains of the mice that had enough exercise weighed about 3％more than those of the mice that did not exercise The mice that exercised are much quicker to learn doing new exercise than the mice that did not exercise．

The results of the experiments suppose the theory that exercise can help babies learn to talk and walk sooner than expected．

The good effects of physical exercise are not limited to children and middle-aged people．Exercise continues to be an important part of our lives after we grow old．For example，people over 50 years old begin to lose calcium(钙) from their bones，which get weaker and can break easily．Physical exercise，however，helps to strengthen the bones and to prevent them from losing calcium．Of course，old people can take medicines to prevent themselves from suffering from losing calcium．But the medicines they take increase the chance of developing some kind of cancer(癌)．So physical exercise is a much safer treatment(治疗)．

1.From the passage we know that         .

2.Active children        than inactive children．

3.Why are the bones of old people easy to break according to the passage?

4.The passage tells people that       .
