2.How long can human beings live?Most scientists who study old age think that the human body is (1)discovered to live no longer than 120years.However,110years is probably the longest that anyone could hope to live--if he or she is (2)completely healthy and lucky.Some scientists even say we can live as long as 130years!Yet,our cells simply cannot continue to reproduce (3)endlessly.They wear out,and as a result,we get old and (4)desperately die.Even though we can't live forever,we are living a (5)longer life than ever before.In 1900,the average American life span (寿命) was only 47years,but today it is 75years!
When does old age begin then?Sixty-five may be out-of-date as the (6)dividingline between middle age and old age.After all,many older people don't begin to experience physical and mental (7)declineuntil after age 75.
People are living longer because more people (8)enjoy childhood.Before modern medicine changed the laws of nature,many children died of common childhood (9)problems.Now that the chances of dying (10)enjoy are much lower,the chances of living long are much higher due to better diets and health care.
On the whole,our population is getting older.The(11)changes in our population will have lasting effects on our social development and our way of life.Some people fear such changes will be for the worse,while some see(12)chances,not disaster,many men and women in their"golden years"are healthy,still active,and young in (13)mind if not in age.
As the society grows old,we need the (14)permission of our older citizens.With long lives ahead of them,they need to (15)turn active and devoted.
