The twentieth century saw greater changes than any century before : changes for the better , changes for the worse ; changes that brought a lot of benefits to human beings , changes that put man in danger . Many things caused the changes , but , in my opinion , the most important was the progress in science .
Scientific research in physics and biology has vastly broadened our views . It has given us a deeper knowledge of the structure of matter and of the universe ; it has brought us a better understanding of the nature of life and of its continuous development . Technology in the application of science has made big advances that have benefited us in nearly every part of life .
The continuation of such activitites in the twenty-first century will result in even greater advantages to human beings : in pure science―a wider and deeper knowledge in all fields of learning ; in applied science―a more reasonable sharing of material benefits , and better protection of the environment .
Sadly , however , there is another side to the picture . The creativity of science has been employed in doing damage to mankind . The application of science and technology to the development and production of weapons of mass destruction has created a real danger to the continued existence of the human race on this planet . We have seen this happen in the case of nuclear weapons . Although their actual use has so far occurred only in the Second World War , the number of nuclear weapons that were produced and made ready for use was so large that if the weapons had actually been used , the result could have been the ruin of the human race , as well as of many kinds of animals .
William Shakespeare said , “ The web of our life is of a mingled yarn(纱线), good and ill together .” The above brief review of the application of only one part of human activities—science seems to prove what Shakespeare said . But does it have to be so ? Must the ill always go together with the good ? Are we biologically programmed for war ?

Since my retirement(退休) from teaching music in 2001 , I have spent a good deal of time painting as an artist . I actually began drawing again in the summer of 1995 when my father died , so perhaps I was trying to recover from the loss of my father , or maybe it was just that it brought back memories of him . In any case , I drew pen and ink animals and landscapes(风景画) much influenced by Krenkel and St. John for five years .
For some strange reason , I had been waiting until my retirement to start doing watercolors again , but as soon as I walked out of the school door for the last time I picked up my brushes and rediscovered Andrew Wyeth , who quickly became my favorite artist . I had looked through all the art books I had on my shelves and found his watercolors to be the closest to how I thought good watercolors should look . So I painted landscapes around Minnesota for three years and tried out many other types of painting . However , watercolors remained my first choice , and I think I did my best work there , showing my paintings at a number of art exhibitions .
Art is now together with my piano playing and reading . There is a time of everything in my world , and it is wonderful to have some time doing what I want to do . As Confucius once said , “ At seventy I can follow my heart’s desire .”
1. What is the text mainly about ?
A. Learning to paint in later life . B. How to paint wathercolors .

4. How does the author probably feel about his life as an artist?

Not long ago , Richard Denniston found himself suffering the same pain that millions of other pet owners have faced . His little Scottish dog had a brain tumor（肿块）and would soon die. Like others who faced the problem before him , Denniston just wanted to end his pet’s suffering . However , he took one step further.
Deniston , an expert who studies animals , collected a tiny skin sample from the dog and took it to his laboratory at Louisiana State University. There he cultivated it and froze it in liquid nitrogen.
From that idea , Denniston started a new technology .Denniston’s company will save pet’s DNA ＄500，plus a monthly storage fee of Us ＄10, until cloning becomes a reality .
Thanks mostly to the contribution of a California multimillionaire , that day may not be so far off.
“It could happen extremely soon if everything went on well.”says Mark Westhusin , a professor leading a dog cloning team . Most experts put successful dog cloning a year to five years down the road . The cost is bound to be expensive at first , but it would eventually drop to a few thousand dollars.
Since Dolly , the sheep which was first cloned in 1997 ,cattle ,goats ,mice and monkeys have been cloned in labs . Pets are likely to be next.
“I really believe that the technology is going to become available for many species in the near future ,”Denniston says .

I know I should have told the headmaster at the time . That was my real 36 .
He had gone out of the study for some 37 , leaving me alone . In his absence I looked to see 38 was on his desk . In the 39 was a small piece of paper on which were written the 40 “English Writing Prize 1949 : History Is a Series of Biographies(人物传记)”.
A(n) 41 boy would have avoided looking at the title as soon as he saw the 42 . I did not . The subject of the English Writing Prize was kept a 43 until the start of the exam so I could not 44 reading it .
When the headmaster 45 , I was looking out of the window .
I should have told him what had 46 then . It would have been so 47 to say : “ I’m sorry but I 48 the title for the English Writing Prize on your desk . You’ll have to 49 it .”
The chance passed and I did not 50 it . I sat the exam the next day and I won . I didn’t 51 to cheat , but it was still cheating anyhow .
That was thirty eight years 52 when I was fifteen . I have never told anyone about it before , 53 have I tried to explain to myself why not .
The obvious explanation is that I could not admit I had seen the title 54 admitting that I had been looking at the things on his desk . 55 there must have been more behind it .
