The food we eat seems to have profound effects on our health. Although
science has made enormous steps in making food more fit to eat, it has , atthe
same time, made many foods unfit to eat. Some research has shown that perhaps
eighty percent of cancer is related to the diet as well, especially cancer the
colon . Different cultures are more prone to contract certain illnesses because
of the food that is characteristic in these cultures. That food related to
llness is not a new discovery. In 1945 , government researchers realized that
itrates and nitrites, commonly used to preserve color in meats, and other food
dditives, caused cancer. Yet, these carcinogenic additives remain in our food,
nd it becomes more difficult all the time to know which things on the pack ging
labels of processed food are helpful or harmful.The additives which we eat are
not all so direct. Farmers often give penicillin to beef and poultry, and
because of this, penicillin has been found in the milk of treated cows.
Sometimes similar drugs are administered to animals not for medicinal purposes,
but for financial reasons. The farmers are simply trying to fatten the animals
in order to obtain a higher price on the market. Although the Food and Drug
Administration (FDA) has tried repeatedly to controlthese procedures, the
practices continue.

If the old maxim that the customer is always right still has meaning, then the airlines that ply the world’s busiest air route between London and Paris have a flight on their hands.
The Eurostar train service linking the UK and French capitals via the Channel Tunnel is winning customers in increasing numbers. In late May, it carried its one millionth passenger, having run only a limited service between London, Paris and Brussels since November 1994, starting with two trains a day in each direction to Paris and Brussels. By 1997, the company believes that it will be carrying ten million passengers a year, and continue to grow from there.
From July, Eurostar steps its service to nine trains each way between London and Paris, and five between London and Brussels. Each train carries almost 800 passengers, 210 of them in first class.
The airlines estimate that they will initially lose around 15%-20% of their London-Paris traffic to the railways once Eurostar starts a full service later this year (1995), with 15 trains a day each way. A similar service will start to Brussels. The damage will be limited, however, the airlines believe, with passenger numbers returning to previous levels within two to three years.
In the short term, the damage caused by the 1 million people-levels traveling between London and Paris and Brussels on Eurostar trains means that some air services are already suffering. Some of the major carriers say that their passenger numbers are down by less than 5% and point to their rivals-Particularly Air France-as having suffered the problems. On the Brussels route, the railway company had less success, and the airlines report anything
from around a 5% drop to no visible decline in traffic.
The airlines’ optimism on returning traffic levels is based on historical precedent. British Midland, for example, points to its experience on Heathrow Leeds Bradford service which saw passenger numbers fold by 15% when British Rail electrified and modernized the railway line between London and Yorkshire. Two years later, travel had risen between the two destinations to the point where the airline was carrying record numbers of passengers.
1.British airlines confide in the fact that__.
A.they are more powerful than other European airlines.
B.their total loss won’t go beyond a drop of 5% passengers.
C.their traffic levels will return in 2-3 years.
D.traveling by rail can never catch up with traveling by air.
2.The author’s attitude towards the drop of passengers may be described
as__.

3.In the passage, British Rail (Para 6) is mentioned to__.
A.provide a comparison with Eurostar.
B.support the airlines’ optimism.

D.call for electrification and modernization of the railway.
4.The railway’s Brussels route is brought forth to show that__.
A.the Eurostar train service is not doing good business.
B.the airlines can well compete with the railway.
C.the Eurostar train service only caused little damage.
D.only some airlines, such as Air France, are suffering.
5.The passage is taken from the first of an essay, from which we may well
predict that in the following part the author is going to__.
A.praise the airlines’ clear-mindedness.
B.warn the airlines of high-speed rail services.
C.propose a reduction of London/Paris flights.
D.advise the airlines to follow British Midland as their model.
