Money spent on
advertising is money spent as well as any I know of. It serves directly to
bring about a rapid sale of goods at reasonable prices, so setting up a firm
home market and making it possible to provide for export (出口) at good prices. By
drawing attention to new ideas it helps greatly to raise standards of living.
By helping to increase demand it causes an increased need for labour, and is therefore a nice way to fight
unemployment. It lowers the costs of many services: without advertisements
your daily newspaper would cost four times as much, the price of your
television program would need to be doubled, and travel by bus or subway
would cost more.
And
perhaps most important of all, advertising provides a promise of reasonable
value in the products and services you buy. Besides the fact that
twenty-seven Acts of Parliament(国会)govern the terms of advertising, no regular advertiser dare produce
anything that fails to live up to the promise of his advertisements. He might
fool some people for a little while through misleading advertising. He will
not do so for long, for the public has the good sense not to buy the poor
goods more than once. If you see product frequently advertised, it is the
proof I know that the product does what is promised for it, and that it has
good value.
Advertising
does more for the good of the public than any other force I can think of.
There
is one more point I feel I ought to touch on. Recently I heard a well-known
television person declared that he was against advertising because it
persuades rather than informs. He was telling us the real difference. Of
course advertising tries to persuade.
If
its message were nothing but information, that would be difficult to get more
people to buy, for even the choice of the colour of
a shirt is a bit persuasive (有说服力的)--advertising would be so boring that no one would pay any attention.
But perhaps that is what the well-known television person wants.

70. The writer thinks that the well-known TV person is
_____.
A. quite right in passing his judgment on advertising

71. In the writer's opinion, ________.
A. advertising can seldom bring material interest to man by providing
information

A new study says
one part of the human brain may become smaller as the result of a condition
known as jet lag. Jet lag results from flying long distances in an airplane.
People with jet lag may feel extremely tired for several days. They may also
have problems thinking clearly and remembering.
Recently a
researcher at the University of Bristol in Britain reported the findings of
his jet lag study, which involved twenty young women who worked for
international airlines. They had served passengers on airplanes for five
years. These flight attendants flew across many countries and at least seven
time zones. In the study, the flight attendants had different amounts of time
to recover from jet lag. Half the women spent five days or fewer in their
home areas between long flights The other half spent more than fourteen days
in their home areas.
The researcher took
some saliva from the women's mouths to measure levels of a hormone(荷尔蒙) that increases during stress (紧张). He tested them to see if they could remember where black spots
appeared on a computer screen. And he took pictures of their brains to
measure the size of the brain's temporal lobes (脑叶).
It was found that
the women who had less time between flights had smaller right temporal lobes.
This area of the brain deals with recognizing and remembering what is seen.
The same group performed worse and had slower reaction times on the visual
memory test. And their saliva samples showed higher levels of stress
hormones.
The researcher
believes the brain needs at least ten days to recover after a long trip. He
says airline workers told him their ability to remember got worse after
working on planes for about four years. Other studies have shown that
increased feelings of stress can cause a loss of cells in the part of the
brain that controls memory.
Scientists say more
tests are needed to study the effects of jet lag on the brain. They want to
find out if too much jet lag could permanently (永久性的) affect memory.
