The Industrial Age and Employment
The industrial age has been the only period of human history in which most people's
work has taken the form of jobs.The industrial age may now be coming to an end,and
some of the changes in work patterns which it brought about may have to be reversed.This
seems a daunting(大胆的)thought. But, in fact, it could offer the prospect of a better
future for work.Universal employment,as its history shows,has not meant economic freedom.
Employment became widespread when the enclosures of the 17th and 18th centuries
made many people dependent on paid work by depriving(剥夺)them of the use of the
land,and thus of the means to provide a living for themselves.Then the factory system
destroyed the cottage industries and removed work from people's homes.Later,as
transport improved, first by rail and then by road, people commuted(乘车往返)longer
distances to their places of employment until,eventually,many people's work lost all
connection with their home lives and the places in which they lived.
Meanwhile,employment put women at a disadvantage.In pre-industrial times,men
and women had shared the productive work of the household and village community.Now it
became customary(惯例的)for the husband to go out to paid employment, leaving the
unpaid work of the home and family to his wife.Tax and benefit regulations still assume this
norm today,and restrict more flexible sharing of work roles between the sexes.
It was not only women whose work status suffered.As employment became the
dominant form of work,young people and old people were excluded-a problem now,as
more teenagers become frustrated at school and more retired people want to live active lives.
All this may now have to change.The time has certainly come to switch some efforts
and resources away from the utopian(乌托邦的)goal of creating jobs for all, to the urgent
practical task of helping many people to manage without full-time jobs.
The established work patterns may be changed with the closing of the industrial age.

[简答题]Sometimes I have thought it would be an excellent rule to live each day as if we should die tomorrow. Such an attitude would emphasize sharply the values of life. We should live each day with a gentleness, a vigor, and a keenness of appreciation which are often lost when time stretches before us in the constant panorama of more days and months and years to come. There are those, of course, who would adopt the Epicurean motto of "Eat, drink, and be merry", but most people would be chastened by the certainty of impending death.
In stories the doomed hero is usually saved at the last minute by some stroke of fortune, but almost always his sense of values is changed, he becomes more appreciative of the meaning of life and its permanent spiritual values. It has often been noted that those who live, or have lived, in the shadow of death bring a mellow sweetness to everything they do.
