in saying that the world is at a crossroad s cr eated by science and technology i know i am not the fir st . but mankind cannot afford to hesitate in indecision . t her e is only one choice for us . we must begin to move along the road to a better future for all the peoples of the wor ld and we must do this now .
by the end of the 20th century , the population of the world might have been doubled . in at tempting to ensur e food , clothing and a dignified standa rd of life for this enormous host of people we must use every weapon that science and technology can give u s . t her e ar e obvious difficulties for the less developed a reas in doing this — for example, lack of capital , dif ferences in social structur e and inadequate k nowledge .

电脑利弊
some people say that the computer is more of a menace than a blessing . what do you think ?
the compute r is a sign of the era , which has brought and is bringing about a t remendous change in our lifestyle . the view that cer tain people maintain that it is more of a menace than a blessing seems ridiculous and completely out of place in a world that has learnt to enjoy and use the computer .
before the invention of the computer , near ly everything was slow . data processing was slow, typing on the typewriter was tedious , accounting was done by hand . it was the computer that sped up all these daily office affair s and fr eed people from repeated drudge ries .
the probable r eason that the comp ute r is a menace is derived from the fact that there a re people who have lost their jobs because the computer has made them r edundant . true, a small portion of people may have lost their jobs because they cannot and will not u se the computer ; however , most companies and work units whe re compute rs have replaced people do not just retrench workers . in st ead , they go through elabor ate progr ammes to ret rain the staff .
another r eason for looking at the computer as a menace is perhaps due to the fact that it makes people waste time playing games . t his is a ridiculous accusation , as time could just as well be wasted watching silly tv programmes . in addition , playing games is interactive and is something that one chooses to do, it is not compulsory . therefore, to call the computer a menace is groundless .
to conclude , the above a re just par t of my a rgument , but i think i have made it clea r that the compute r is a bles sing instead of a menace . however , ther e is still enough space for counter- argument .
