Over the last 25 years, British
society has changed a great deal – or at least many parts of it
have. 1. . Ideas about social class – whether a person is “working - class” or “middle - class” – are one area in which changes have
been extremely slow.
In the past, the
working-class tended to be paid less than middle-class people. The typical
working man would collect his wages on Friday evening and then, it was widely
believed, having given his wife her "housekeeping", would go out and
squander(挥霍) the rest on beer and betting.
The old style of what a
middle-class man did with his money was perhaps nearer the truth. He was-and
still is-inclined (有意) to take a longer-term view. Not
only did he regard buying a house as a most important thing, but he also
considered the education of his children as extremely important. 2. . Only in very few cases did workers have the
opportunity (or
the education and training) to make such long-term
plans.
3. . In a large number of cases factory workers
earn as much as their middle – class supervisors (管理者). Improved social
security and laws have made it less necessary than before to worry about
"tomorrow". Working-class people seem slowly to be losing the feeling
of inferiority(自卑感). In fact there has been a growing
tendency in the past few years for the middle-classes to feel slightly ashamed
of their position.
4. .They generally tend to share very similar
tastes in music and clothes, they spend their money in having a good time, and
save for holidays or longer-term plans when necessary. There seems to be much
less difference than in precious generations. 5. . As long as this gap exists, there will
always be a possibility that new conflicts and jealousies will emerge, or
rather that the old conflicts will re-appear, but between different groups.
A. Nowadays, a
great deal has changed
B. Both of
these provided him and his family with security
C. As a
result, differences in life – styles and attitudes came into
existence
D. However, we
still have a wide gap between the well –
paid and the low - paid
E. In recent
years, the working – class people have begun to
design long – term plans
F. In some
ways, however, very little has changed, particularly where attitudes are
concerned
G.
The changes in both life–styles and attitudes are probably
most easily seen amongst younger people
